When I turn on the computer, the fan hums. The computer is very noisy - what should I do? What you need to do to get rid of noise from the system unit

Read why your computer is noisy and what to do. All causes of strong noise from the power supply and system unit. Ways to fix it yourself.

Almost every desktop computer user has encountered a situation where extraneous noise is heard from the system unit. There may be several reasons for this. If the computer begins to make noise, then measures must be taken immediately. This may be a sign of a serious breakdown or cause the failure of the main components of the PC.

Determine where the noise is coming from in the computer?

First of all, find out why your computer is making noise. To do this, listen to it while working. Most often, users complain about noise in the evenings, since at this time it is heard more clearly. Extraneous sounds can occur for various reasons:

1. Features of the hard drive. Old full-size models made an unpleasant grinding noise when writing or reading files; if it is too distinct, then it’s time to check the performance of your storage device - after all, you don’t want it to fail at the most important moment for you. Modern solid-state drives operate silently; if you notice a grinding noise during their operation, you need to check the motherboard and power slot.
2. The graphics card can also become a source of noise, especially if you have installed a powerful option on your PC with a large cooler or even multiple fans. Most often, the cause is dust between the cooler blades or its design features.
3. The processor fan also accumulates dust; in addition, dirt can also be found on its axis, which leads to braking, grinding and other extraneous sounds. The number of revolutions of the cooler when dust accumulates also decreases, which leads to the computer freezing and reducing its operating speed.
4. Another fan that can make loud noise is located in the power supply. Some experts recommend changing the unit every 2-3 years. This procedure can give you confidence that your computer is fully functional.
5. The optical drive may make unpleasant sounds when reading a disc, which indicates a malfunction. If you notice them, then be prepared to abandon this device in favor of additional inputs for flash drives or replace it with a new one. The optical drive cannot be repaired. If you hear noise when there is no disk in the device, then you should look for it in another place; the drive starts working only after placing a storage device in it.
6. The appearance of dents, chips and cracks on circuit boards can also become a source of noise. Coolers force air inside the device, which causes the parts inside to whistle and rattle.
7. If you assemble the computer yourself, you need to carefully check the fastening of the parts. Insufficiently tightened bolts, lack of cable ties and vibration from computer operation lead to rattling.

These are the main reasons why extraneous noise occurs during computer operation. Now let's look at what you can do at home. Not all of these problems can be solved; sometimes you just need to change one of the component devices.

Is your computer noisy? Clean the cooler from dust!

The cooler located on the central processor attracts the maximum amount of dust. As a result, it begins to hum, crackle, and rotate several times slower. In advanced cases, the computer completely stops starting. This happens because the thermal paste dries out due to periodic overheating. It must be replaced during the cleaning process.

If your computer is under warranty, do not open the system unit yourself, but take it to an official service center.

Cleaning from dust is a paid procedure, but the craftsmen will restore all seals and if your hard drive, motherboard or other equipment breaks down, you can qualify for a warranty replacement or repair.

For out-of-warranty computers, you need to do the following:

1. Completely disconnect the computer.
2. Remove the side cover from the system unit.
3. Disconnect the fan from the motherboard, the connector is usually located next to the heatsink.
4. Remove the radiator and cooler together. To do this, you need to press a small lever located under it or on the side.
5. Use a small vacuum cleaner, hair dryer or cotton swabs to remove all dust from the cooler.
6. Thermal paste is smeared on the bottom of the radiator; if it looks like dried chewing gum, then you need to remove its remnants with a cotton pad and then apply a new one.
7. Reassemble in reverse order.

Thermal paste can be purchased at any PC component store; it is sold in small tubes. Do not use wet wipes to clean the radiator and cooler. Do this work only with dry improvised means - brushes, cotton swabs. Otherwise, a short circuit cannot be avoided. It is very good to blow out dust with air. It is best to use a vacuum cleaner that is not too powerful, for example, one designed for cleaning the interior of a car.

If necessary, if the computer fan makes noise after cleaning, you can disassemble the cooler and lubricate its axis with silicone. To do this, you need to peel off the sticker from the cooler, remove the small cap and drop a little lubricant into the opened hole. This only needs to be done if your computer is old. New PCs do not need to be completely disassembled.

How to clean the power supply

You should do the same if the computer power supply is noisy due to accumulated dust. You need to open the assembly, clean it and lubricate the cooler axis. In this case, you need to use the same available means. Just remember that old Soviet vacuum cleaners are not suitable for cleaning power supplies - they are capable of producing electrostatic charges that will destroy the circuit board of this unit.

Some power supplies cannot be disassembled; in this case, the unit must be replaced completely. If you find that the computer is noisy when turned on due to the power supply, then you need to carefully inspect it while it is running. Sometimes grilles are installed on the back, which are fastened with screws. Over time, the fastenings become loose and the fan blades can touch the grille. In this case, there are two options - remove it entirely or tighten the screws.

Checking the hard drive

There is another reason why your computer makes a lot of noise. Grinding and knocking noises when accessing a hard drive are only possible if you are using an old, bulky model. Nowadays such media are not installed on computers. Every year hard drives become more and more compact. Replace the old HDD with a solid state one.

You also need to check how well the media is secured inside the system unit. If necessary, tighten the screws and place a thin rubber gasket under the disc. Small media can be placed in the slots if you buy a special casing for them.

Checking the operation of the video card

Inspect the video card. It can also be a source of noise, but simple cleaning will not get rid of the problem. The video card is upside down, and it also has a small cooler. Due to the peculiarities of its placement, after dust enters, the axis of the component shifts.

In this case, disassemble and clean the cooler, lubricate the axle with silicone. Try to twist the cooler slightly to see where the axis has shifted. If the blades touch one of the walls of the housing, then you need to cut it down slightly. Some experts even recommend removing as much of the protective cover as possible for the cooler, while other experts believe that if such a breakdown occurs, you need to change the video card or look for a new fan that fits the size.

What else can you do if your computer is making a lot of noise?

If you find cracks and chips on the boards, or a broken optical disk, then you should not fix the problem yourself - in most cases, only replacing the damaged components can save you from extraneous noise.

Didn't all of the above help? And your computer is very noisy. What to do? In this case, all you have to do is upgrade your computer.

To do this you need to do:

1. Replace the air cooling system with a liquid one. This option is suitable for gamers who value high performance and trouble-free operation of their computer. It is also rational to use liquid cooling if you work on a PC, performing actions using programs that require high performance. You should not install a liquid system on a standard office computer or one that is used for listening to music or surfing the Internet. In this case, the costs of the system will not justify themselves.
2. If you decide to leave the system with air, then you should pick up modern silent coolers in a store that sells PC components. Before purchasing, pay attention to the information about the fan located on the sticker. It indicates the required current for the cooler to operate and the number of revolutions. Measure the diameter of the device to purchase an analogue that is suitable in size.
3. If there is no reason for the noise, you need to think about placing your PC components in a new case. Very often, people who assemble powerful systems based on a simple office box are faced with the fact that the finished machine is very noisy. This only means that the housing is not suitable for soundproofing characteristics. Replace it with a new one that can absorb vibration from operating equipment.

Remember that you can work peacefully only if you regularly monitor the cleanliness inside the system unit. If you are not confident in your abilities and are afraid that you will not be able to clean the coolers, you should bring your PC to a service center for preventive cleaning. This service is paid, but it is much cheaper than a new processor or video card.

Now you are not afraid of the situation when your computer is noisy. You know what to do in it. If you have any questions, you can ask them in the comments. Share information with friends, discuss.

Are you familiar with the situation when you hear extraneous noise from the system unit? This is not only unpleasant, but it is also always a warning that some part of the system unit may soon fail. You need to get rid of this phenomenon as soon as possible so that the coming sound does not irritate your ears, and the computer’s performance does not decrease due to increased wear of parts. Offering to understand in detail the problem, why the computer is noisy and what needs to be done to get rid of excess noise during its operation and return the computer to its original operating mode.

The main causes of computer noise

Computer noise is not as noticeable during the day as it is at night. Imagine that you need to work or just relax by watching a movie or browsing the Internet. Agree to do this accompanied by strange sounds emanating from the system unit, which is not entirely pleasant, and sometimes even irritating. Therefore, I will now talk about the main malfunctions that lead to the appearance of strange sounds from the computer system unit in the sequence of their possible appearances.

Hard drive problems

The cause of extraneous noise may be the operating characteristics of the hard drive. This often becomes noticeable when some information is copied and recorded. In this case, not only noise can occur, but also tapping and grinding. The occurrence of such sounds may indicate poor-quality material or wear of the mechanism, so noise may appear either immediately after purchasing a PC, or after its long and persistent use.

I would like to note that the hard drive can make some sounds in the form of crackling sounds from the first time it starts working. This applies to inexpensive or older models. High-quality expensive models operate quietly or almost silently.

There is no point in delaying the solution to such a problem (especially if the hard drive was working quietly before), because if the HDD drive stops working, you will irretrievably lose all documents and files stored on the computer. In order to avoid such an unpleasant situation, you need to carefully consider the choice of hard drive, pay attention to the advice of sellers and reviews of owners.

If you already own a noisy hard drive and there is no way to buy a new one, I suggest two ways to solve this problem:

1. Reliable fastening (fixation) of the disk in the system unit case using special soft gaskets. This will get rid of resonance and vibrations.
2. Reduced read head positioning speed (Automatic Acoustic Management or AAM for short), which creates a characteristic crackling sound. This can be done using the quietHDD program in the AAM Settings section. The program must be added to startup.

Video card

It is this device that always creates the maximum amount of noise (hum) in the room where the computer is installed. The reason is not the video card itself, but the cooler (fan), which serves to cool the board. Basically, it is quite small in size, but this is quite enough that it can become a source of loud and unpleasant noise. Modern powerful video cards are equipped not with one fan, but with two or even three, which can increase the noise many times over.

Most often, fans are made on bushings, and when dust gets into it, the bushing breaks. Because of this, the fan blades can reach the edges of the video card case. Getting rid of such a source of noise is not easy. The simplest solution would be to replace the cooler.

There is another way to solve this problem. To do this, you initially need to disconnect the video card from the motherboard, disassemble it in order to get to the cooler and lubricate it, which is very problematic. Please remember that this device is quite fragile and can be easily damaged. If you still manage to get to the axle, then you must first check it for integrity and then lubricate it with silicone oil. It perfectly prevents noise during operation.

If the axis has nevertheless shifted and during operation the fan blades rub against the edges of the housing, then the housing itself can be cut down or cut off. True, it should be noted that this will not look entirely aesthetically pleasing, but it will allow you to get rid of annoying noise without extra costs.

CPU fan

This reason is very common and creates a huge amount of inconvenience for users. The motherboard contains a processor, which is also often called the “stone”. So, a radiator with a cooler is additionally installed on it. This design is very bulky in appearance and at the same time collects dust well, which accumulates between them. A large layer of dust gradually increases and complicates the movement of the fan and creates noise. In addition, dust enters the axle, which causes a decrease in speed and a hum appears.

Solving this problem is quite simple. First of all, you need to disassemble the processor cooling system and clean the fan and radiator from dust. Then you need to disassemble the radiator itself and lubricate the axle with the same silicone oil. During assembly, make sure that the screws are well tightened to avoid vibration.

power unit

Experts recommend replacing this device every 2-3 years, since it is responsible for the safety of the entire computer. During this period of time, all internal parts of the block become dusty, since the block also contains a cooler, which serves to cool the parts. With the blown air, dust and debris particles get inside the device, which, as in the case of a video card and cooler, cause noise. However, in this case, the noise level is much higher, since the rotation speed and diameter of the fan are much larger, and not all computer equipment manufacturers care about creating a silent fan in the power supply.

You can get rid of the noise yourself by disassembling, cleaning and lubricating the fan. However, it should be taken into account that not all block models allow easy access to the content. You can also remove the protective grille near the fan, which will help reduce noise or eliminate it altogether.

In order to get rid of noise and be sure that the power supply is working properly, the best solution would be to purchase a new device to replace the old one.

Optical drive

In one of the least common situations that still occurs in practice, the cause of noise may not be the entire system unit of the computer, but only the optical drive, which is better known to users as “CD DVD ROM”. The reason for the noise in this case is the poor quality of the device. In this case, you need to be quite careful, since noise can only occur when the disk is in the device. If there is nothing in it, then there will be no noise.

If this particular device is the cause of the hum, we have to disappoint you, since it is practically beyond repair. It should be noted that they are not repaired even in warranty service centers, and in case of breakdown they are simply replaced with new ones. The best solution would be to completely abandon the use of such devices in favor of flash drives, which today are already very common and are used everywhere. In addition, with their help you can carry out all necessary operations, including even.

Any device or motherboard is cracked

Noise can arise for various reasons and this can occur not only due to manufacturing defects, clogging or defects in the operation of the cooler, but also for completely physical reasons. For example, the cause may be a crack on the motherboard, a crack in the video card case, or the presence of various debris in the system unit, etc. Due to the effect on the part of the air pumped by the coolers, whistling, rattling or other extraneous sounds may occur, which are usually not observed during normal operation of the system unit.

In order to establish the cause, it is necessary to check the contents for any defects that could arise as a result of an intentional or unintentional impact. For example, some PC users may hit the system unit out of anger while the computer freezes. As a result of such actions, all kinds of defects arise, including dents, chips, cracks, etc.

Fastening parts

If the computer is noisy or makes an unusual noise, you need to check all the fasteners inside it.

In order to carry out this check, you first need to open the unit cover. After this, tighten all the screws and screws that you can reach with a screwdriver (Phillips). You need to start with the motherboard, to which a large number of components are attached. If any of the blocks is poorly secured, during operation the motherboard begins to vibrate and at the same time touch the metal case of the system unit.

Then you should check the fastening of the video card and processor (especially the cooler). Next, you should pay attention to the mounting of the hard drive. If it does not have an anti-noise fixation that uses slotted gaskets or plastic holders, you can be sure that extraneous noise arises for this very reason due to poor fastening of the hard drive. In order to make the noise level significantly lower, you can lay a small layer of rubber between the metal fasteners. It will soften the vibration that occurs during operation, preventing it from spreading throughout the system unit. The optical drive needs to be secured in the same way. After this work is completed, check the power supply. Don't forget to tighten the mounting bolts and screws. If there are additional coolers in the system unit, then you need to check them too.

A very important point will be the correct installation of connecting wires and cables. All of them must be connected to each other with plastic ties (clamps) and laid so as not to touch the fans.

What needs to be done to get rid of noise from the system unit?

If the problem of extraneous noise does not lie in the components, but you do not want to hear the computer operating at all, you can take several actions that will allow you to almost completely get rid of the noise of the system unit.

Changing the cooling system

If you want to eliminate noise once and for all, you should radically change the cooling system, namely, replace it with a liquid one. When using this system, computer components are cooled not by fans, but by liquid using specialized pumps, heat sinks, sensors and other devices.

A liquid cooling system can almost completely eliminate noise, but the cost of such a system is quite high and amounts to about 500 (and in some cases more) US dollars. This is quite an expensive pleasure that not every PC user can afford.

In order to significantly reduce the noise level, sometimes it is enough to replace the system unit case. You can purchase a case with vibration and noise insulation, or make it yourself. Also think about whether the legs on which the system unit is located are capable of absorbing vibration well, for example, being rubberized.

One of the most acceptable ways is to replace coolers with modern, quieter ones. It should be noted that when carrying out this action, you should not waste time on trifles, otherwise there will be no noticeable effect.

You may need to install a more powerful fan that will not work at its maximum capacity, thereby creating noise or hum.

Regular PC cleaning

Regular cleaning of your computer is very important and beneficial for the system unit, so this operation should be carried out periodically (once every six months). This will save you from various problems, including the occurrence of various noises in the computer system unit.

I hope I explained to you in detail why the computer is noisy and what needs to be done to get rid of extraneous sounds. Take care of your computer and it will work properly for many years!

It should be remembered that this electronic-mechanical device, despite its high technology, has the ability to wear out, break, and become dirty. Such design changes in machines are usually accompanied by various sounds: rattling, humming, crackling. Most often, the sources of extra decibels in a computer or laptop are cooling system fans, hard drives and drives, as well as the system unit case.

If a brand new computer suddenly starts making noise, then most likely it has a manufacturing defect. In such cases, it is recommended to contact the seller and request that the problem be corrected. If you discover that your computer is noisy after the warranty period for its main components has expired, you will have to get rid of the excess sound from the system unit yourself. As a last resort, there are service centers in every city that can easily help you get rid of this trouble.

The main and most common problem on a computer is malfunctioning fans of the processor, power supply, video card, and case. In order to find the source, you need to remove the cover from the system unit and, in turn, for one second, stop the rotation of each fan with your hand.

If the culprit is found, then you should turn off the computer, disconnect it from the network and begin troubleshooting. To do this, you may need a screwdriver, an oil can, and possibly thermal paste.

First of all, you should clean the fan blades from any dust adhering to them. Dirt, with its weight, changes their center of gravity and aerodynamics, which leads to wear of the bearings and, as a result, rattling and noise.

Dust deposited on the CPU cooler heatsink interferes with heat transfer and leads to overheating. As a result, the cooler fan is forced to spin faster, providing sufficient cooling. Hence the extra buzz.

If there is reason to believe that the noise is coming from the bearings of the rotating elements, then you should lubricate them with special oil using an oil can.

When all measures to clean and cool the processor have been carried out, but have not given a positive result, you need to try replacing the thermal paste. Alternatively, accelerated rotation of the cooler fan may occur due to incorrect settings in the BIOS.

One of the computer functions is the operation of hard drives. The sounds produced by a hard drive can have two sources: the disk rotation mechanism and the positioning head for reading and writing information.

In the first case, it will not be possible to get rid of the noise, since the hard drive is most likely worn out. In the second case, you can adjust the speed of the heads using a special program downloaded from the manufacturer’s website, or, alternatively, using the AAMTool or MHDD utilities.

Other, more rare reasons why a computer is noisy are a malfunction in CD or DVD drives, poor fastening of these devices, or the use of dirty, stained CDs.

Disks in an optical drive rotating at maximum speed can make a lot of noise. To watch movies and play music, such speeds are not needed, so they can be limited using special utilities, for example, Nero.

Sometimes the culprit for a noisy computer can be the system unit case itself. Vibrations and vibrations transmitted from internal components to housing covers through loose or loose fasteners turn into rattling sounds. To eliminate resonance, you should secure the device more tightly to the body somewhere, place a rubber washer somewhere, and glue a noise-insulating, vibration-absorbing material somewhere.

It happens that your computer starts to make a lot of noise and it annoys you, in this article we will look at why the computer is noisy and how to remove computer noise

Why is my computer so noisy?

The main source of noise in the system unit is the cooling system, namely the fans.

How to make your computer quieter? Here are several ways to eliminate noise in the system unit:

Cleaning the system unit from dust

Your computer may not become louder immediately, but as soon as enough dust accumulates in it. Due to dust, the computer may not even turn on. Dust impairs heat dissipation from cooling system radiators and can even stop fans from rotating if there is too much dust.

It is best to clean the system unit outdoors using a compressor or a can of compressed air.

Adjusting fan speed via BIOS

In order to enter the computer's BIOS, you must immediately press the Delete key, or F2, after turning on the computer - depending on the motherboard manufacturer. In the computer BIOS, find one of the parameters that regulates the speed of coolers: SmartFan Function, CPU Smart Fan Control, CPU Smart Fan Target, CPU Q-Fan Control - the name of the parameter may vary, but the meaning does not change. The value of this parameter should be set to Enabled, Auto or, if possible, specify the temperature at which the cooler speed will increase. Keep in mind that the processor temperature should not exceed 60-70 degrees C.

In the same way, you can adjust the rotation speed of the system cooler (System Fan). Replacing fans

Replacing fans is necessary if, after turning on the computer, it hums, rumbles, or makes noise for a couple of minutes. Later the noise decreases. This is due to worn fan bushings. You can, of course, lubricate them, but, as a rule, this does not help for long.

You can significantly reduce noise by replacing the fans with larger coolers. The larger the fan, the slower its blades rotate, and therefore the quieter it is. For example, instead of an 80mm fan, try installing a 90mm or even 120mm fan. Unfortunately, if you have a power supply with an 80mm fan, the only way to reduce computer noise is by replacing the power supply.

Installing a liquid cooling system

Installing a liquid cooling system can provide you with complete peace of mind. But you need to immediately estimate that such systems are not cheap, and their installation must be done very carefully so that there are no problems with tightness and liquid leakage into the system unit.

And, of course, you should not reduce the noise of the computer by closing it in a desk drawer - this threatens it with overheating.

The system unit is noisy. What to do?

In general, the system unit may make noise initially, immediately after purchase, and there are objective reasons for this. It’s much worse if he started making noise literally out of the blue - there was a constant noise. Why is this happening? How to remove noise? This is discussed in today's article.

Buying a silent system unit

• Power supply fan.

• CPU fan.

• Fans in the system unit that serve for better cooling.

• The design of the system unit, which amplifies sounds.

Generally speaking, today components have become noticeably quieter than before, but they still produce sound. Moreover, there is no escape from it, but you can make sure that the computer makes as little extraneous noise as possible.

First of all, this is the body. It should be made of thick steel, which does not allow the metal to resonate. Inside there should be seats for hard drives and a floppy drive, with rubber dampers that significantly reduce vibrations.

Hard drives can create a lot of noise. For the operating system, you can safely use SSD drives, which do not make any sounds at all. As for the hard drive that will be used as a “file dump,” you can choose, for example, an external hard drive and connect it only when you need it. If you can’t do without a regular hard drive, then choose the model that makes the least noise. There are such on the market, you can read about them on computer forums.

But you can’t do without a fan for cooling. Fortunately, many of them are practically silent and only make themselves known under increased load. The same can be said about the power supply. In general, you shouldn’t skimp on buying a power supply - it’s better to buy products from a company that has been proven over the years. It may be a little more expensive, but you will get a high-quality and almost silent power supply.

In general, today there are no problems with assembling a silent system unit; you just shouldn’t buy the first components you see. It is better to scour the forums on this issue and choose quality components.

Software fault

Well, now let's move on to those cases when the computer starts to make noise literally out of the blue. While we won’t disassemble the system unit, let’s try to find the cause of the malfunction.

Many users do not install antivirus on their systems. But even if an antivirus is installed, this does not mean that the computer is completely protected from attacks from outside. It is quite possible that there is already a virus on your computer, and probably more than one. There are a great many viruses and they pursue different goals. Some of them completely load the processor (up to 100%). When this happens, the processor heats up. At this moment, the fan starts working hard to cool the processor. It is he who can create the very noise that you don’t like.

You can see what exactly is loading the processor so much using the task manager. The “Processes” tab displays processes, as well as the percentage of processor load.

If this is your case and something is loading the processor, use an antivirus and antivirus utilities, for example, Cureit from Dr.Web. If the treatment is successful, the noise from the fan will disappear.

When under load, video card coolers can make noise. This is normal, especially if you decide to play the latest game at maximum settings.

It's another matter when the video card starts to make noise even without running games or programs. Most likely the problem is one of the fans that cools the device. It is noteworthy that the fan itself may be working properly, but over time the cooler axis often shifts, as a result of which its blades begin to touch the case and cause an unpleasant sound.

In this case, you can change the fan itself, but this is not so easy because you will have to disassemble the video card. In some cases, it may be easier to lightly trim the edges of the blade if possible. Not very aesthetically pleasing, but practical.

HDD

I have already written about the noise coming from hard drives. Some models are so noisy to begin with that you even ask yourself if they are really in working order?

In this case, there are few options - either use SSD drives, or choose a case that is resistant to noise, or look for a hard drive that makes the least noise.

If the disk begins to “weep” after a certain period of operation, this may indirectly indicate wear of the mechanism. It is recommended to check the disk using special utilities and if it shows results that indicate a malfunction, you need to transfer the information to another source as quickly as possible before the hard drive gives up its life.

Hard drives can be repaired, but no one can tell you how long they will “live” after that.

CPU

If your CPU cooler is noisy due to something other than a software issue, it is likely clogged with dust and dirt. Cleaning the processor is not difficult, the main thing is to prepare. I talked in detail about how to clean the system unit and the processor in particular just a few days ago. Let me remind you that cotton swabs and a paint brush are best for cleaning the processor, and a vacuum cleaner will come in handy to collect dust. Just do not forget to turn off the computer itself, including from the outlet.

power unit

As in other cases, the power supply cooler tends to make unnecessary sounds, including due to accumulated dust. To clean the power supply, it must be disconnected from the motherboard and disassembled. The activity is not the most interesting, but for some it is difficult, so if you are afraid that you will not be able to assemble the device, it is better not to disassemble it yourself, but trust the professionals.

Do not forget that many power supply models themselves are very noisy.

And another important moment. All fans can make noise due to lack of lubrication. This applies to all coolers. Lubricating the fans is not a problem, you just need to choose the right composition and not overdo it.

Fastening parts

And also look at how the parts are secured inside your system unit. For example, hard drives must be in their designated cages. Also tighten any bolts and screws you see. Check the power supply too - it's a large device that can resonate a lot if not secured correctly.

Pay special attention to the side covers of the system unit; they are also secured with bolts.

The computer started making noise, what should I do?

It is impossible to work at a computer for a long time when it is very noisy. The noise also irritates others, especially at night. Let's see what you can do about your computer if it has become terribly noisy.

The following components can produce noise:

Fans

They are also coolers, installed on power supplies, processors, video cards, and simply in the case to lower the overall temperature of the system unit.

Fans start to make a lot of noise when they are malfunctioning or operating at maximum speed.

The fan runs at maximum speed when it cannot cope with cooling. Therefore, it is necessary to check whether the radiators on the processor and video card are clogged with dust. You may need to replace the thermal paste if your computer is many years old. Perhaps the computer is having difficulty coping with the load placed on it and more powerful components are needed.

You shouldn’t simply reduce the fan speed using programs or settings in the BIOS without having enough experience to do so. Otherwise, the computer will work quietly, but will soon burn out. You can set the fan control in the BIOS to automatic mode. Then the speed will be adjusted depending on the temperature.

Before lowering the fan speed, you must install additional fans in the case and lower their speed too. Then, with the same level of cooling, the computer will be quieter. You need at least two additional fans to install in the case. One works to blow air into the front part of the case, and the other works to blow air into the rear part of the case.

The fan speed can be reduced using special regulators. There are cheap options when each regulator is connected to one fan. It’s also more expensive when a special panel with regulators and a screen for monitoring cooler speed and temperature is installed on the front of the system unit. Fans are connected to this panel inside the system unit.

Expensive fan models are quieter and last longer. Larger fans are less noisy. You can install a radiator with cooling pipes on the processor. Then the cooling will improve and the fan will spin slower. And on processor models that are not prone to strong heating, you can completely disable the cooler. But this occurs mainly on “thin” workstations and media centers.

After lowering the fan speed, you need to make sure that the cooling is working effectively enough. You need to monitor the temperature of the components. If the temperature does not rise, especially under load. Then everything was done correctly.

Fans may be noisy due to foreign objects getting into the fan. For example, wires when they are poorly secured and are located next to rotating blades.

HDD

They can make quite loud sounds when operating. Especially when they start to fail. Therefore, if your hard drive starts to run louder than usual, then you should check its technical condition with special programs, such as CrystalDiskInfo, and make backup copies of important data.

Different models of hard drives can operate at different volumes, and it is also possible to control the noise emitted using programs on some models. But this reduces the performance of the drive. You can also replace the hard drive with an SSD drive if finances allow. But SSD drives are silent and faster.

It often happens that after some time the computer system unit begins to make a lot of noise, although in general it works properly and fully copes with the tasks assigned to it. There can be quite a few reasons for this, and they can be both software and completely “hardware” in nature. We will try to highlight the most common cases of this malfunction and teach you how to fix them.

Software fault

The first thing you need to do before disassembling your PC is to rule out a software malfunction. After all, if your PC is actively processing any task, it will heat up and, accordingly, the cooler speed will increase and create noise.

After the spread of cryptocurrencies (Bitcoin, Litecoin, etc.) and various “farms” that mine them over the network, so-called miner viruses began to spread. That is, using the power of your computer, some particularly enterprising person earns money (coins). Depending on the settings of this virus, your video card or processor will be loaded at 25, 50, 75, 100 percent, or any other arbitrary figure. Moreover, the miner can disguise itself as any other program or system library. It is worth noting that not everyone will be able to detect such programs and consider them a threat, which makes it difficult to find such malware.

In order to check whether this is your case or not, you need to open the task manager in the processes tab and sort them by CPU load percentage. If your “System inactivity” takes up about 97-99% when your PC is idle, then most likely this is not your case, but if any process is actively loading your PC, then you should determine its location and “Google” its name - perhaps , it is he who is this “malware”.

Dust on fans or their failure

Dusty, poorly functioning fans can also cause PC noise. In addition, if their axle becomes loose over time or at least one blade breaks, this will also cause unpleasant noise.

If the blades break, they must be replaced separately or purchased a completely new fan. If they are working, but have collected a lot of dust, then it is necessary to remove it by cleaning (either remove the blades and wash, or clean with a brush and cotton swabs). Also, don’t forget to check if dust has collected on the video card and processor fans.

Hard drive noise

Another source of noise can be. Either over time or due to a manufacturing defect, it can make unpleasant sounds during operation. Unfortunately, this behavior is quite often a harbinger of imminent hard drive failure. Therefore, we recommend that you first save to a flash drive, burn to discs, transfer the most important information for you to another hard drive, and then go to the nearest computer store for a new hard drive.

However, unpleasant sounds can also be produced by a fully working hard drive that will last for many more years. This can happen due to improper installation or loose fasteners. This oversight can be corrected with a simple screwdriver, so before you run to the store, determine which of these two cases is yours.

Power supply cooler

If all of the above does not apply to your case, then you should check the serviceability of the power supply cooler. Yes, there is also a cooling fan there, and according to statistics, it fails first, starting to make an unpleasant noise.

You should disassemble the power supply and inspect it. You need to clean it from dust and lubricate the axle. In most cases, this should remove all noise. If this does not help, then most likely you will need to either take the power supply in for repair or buy a new one.

That's all, following these tips, you can easily eliminate unpleasant noise when your computer is running. Of course, this is not the most exhaustive list of problems, but in most cases problems arise precisely because of the above.
