How to upgrade the computer processor radiator mounting system. What to do if the radiator is removed from the processor How to remove the cooler from the processor. Correct Actions

Computer equipment, like any modern electronic devices, requires, although minimal, regular maintenance. If dust on the motherboard or in the power supply can cause short-circuiting of adjacent tracks and failure of the entire computer, then dirt and dust accumulating on the surface of the fan leads to its weight and, as a result, to a decrease in rotation speed and a decrease in air flow. This very often leads to overheating of all computer components and causes freezes and crashes (with minor contamination) and even failure of important system components (if the fan is not cleaned in a timely manner). The load on the bushings (bearings) of the fan itself also increases and the service life of this work is significantly reduced. Therefore, it is necessary to monitor the cleanliness of the fan surface and promptly remove dust. The need for such a procedure is indicated by loud sounds from the system unit (or from the laptop case), especially when turned on.

We have prepared step-by-step instructions in which we will tell you how to disassemble and clean dust from coolers installed in a computer or laptop. But if you are not confident in your abilities, technical experts can do this.

How to clean a computer fan

For this purpose you need to prepare:

• tweezers;
• sharp scalpel or thin knife;
• cotton swabs and brush;
• alcohol;
• silicone grease (if you don’t have it, you can use a “spindle”).

It is also advisable to have a can of compressed air or a vacuum cleaner, with the tube connected in the opposite direction - for blowing. And of course, a screwdriver for disassembling the computer and removing the fans.

Before you begin disassembling your computer, you must disconnect it from the power supply by disconnecting the power cord from the system unit. It is also recommended to remove the connectors from other system elements (monitor, local network, additional audio and video devices). In this case, it is necessary to remember or sketch the existing diagram of mutual connections to facilitate assembly.

The first step in cleaning the fans is to provide access to the inside of the system unit. To do this, remove the side cover, having previously unscrewed the fastening screws with a screwdriver. At the next stage, you can use a vacuum cleaner to carefully blow away dust from the internal surfaces and components of the system unit, which will make working with the fans easier. After this, we visually find all the fans inside and begin cleaning them.

In most cases, the system unit has several types of air blowers: a processor cooler, one or more fans inside the case, cooling propellers on the video adapter, and a fan on the power supply. Depending on the purpose and installation location, cleaning has its own characteristics.

How to remove the cooler on the processor, power supply and video card

When cleaning the processor cooling system, extreme care must be taken to avoid damaging the chip and its surrounding components. There are several options for attaching the fan to the radiator of the processor unit: with latches, using a bolted connection, and non-removable structures. In the latter case, you can only perform surface cleaning and blowing out dust. If the cooler is secured with latches, just use a flat screwdriver to bend them a little and pull the fan out of the so-called “locks”. When bolted, it is enough to disassemble the structure with a screwdriver. After this, disconnect the cable from the socket on the motherboard, remembering its correct location.

To remove and prepare the power supply fan for cleaning, you must completely dismantle the power supply, first disconnecting all connectors from the motherboard, hard drives and other components. After this, use a screwdriver to unscrew the fastening bolts located on the back of the “system unit”. After removing the power supply, you must carefully remove the cover from it (attached with special screws), providing access to the cooler.

To access the video adapter fan, it is best to remove it from the PCI connector and start disassembling and cleaning it on the table. The remaining fans located on the walls of the system unit can be removed without any problems, since they are secured to the case with bolts or special easily removable clamps. Before maintenance, they must also be disconnected from the power connectors.

How to disassemble and lubricate a fan in a computer

Despite the fact that upon quick inspection the fan appears to be non-separable, it is quite easy to disassemble. To do this you need:

1. using a thin knife or scalpel, pry and remove the rubber plug, which is usually located under the label;
2. remove the retaining ring;
3. Carefully insert the tip of the knife into the stopper slot and lift one of the sides of the ring;
4. remove the special rubber plugs that protect the internal mechanism of the device from oil.

After this, you can proceed directly to cleaning. For this:

1. The two parts of the fan are disconnected. The one that contains “electronics” is wiped with a dry cloth or cotton swab or blown with a powerful air stream (from a can of compressed air or a vacuum cleaner). The other part can be washed with running water;
2. at the next stage, use a cotton swab dipped in alcohol to remove the remaining old grease and dirt;
3. after this, it is necessary to treat the internal parts with silicone oil or, in its absence, with a “spindle”, dipping a cotton swab into the liquid. The lubricant must be rubbed evenly over the surface of the mechanism, avoiding its contact with the electronic coils. Lubrication will protect the mechanism from moisture, overheating and many other problems;

How to assemble a cooler

As always, assembly should be performed in reverse order:

1. put the impeller on the “electronics”;
2. place both rubber plugs on the rod one by one;
3. install the retaining ring holding the top of the blade part in place;
4. close the mechanism with a plug;
5. Reinstall the fan and connect it back to the circuit.

After this, you need to connect the previously removed connectors and, after checking the correct connection, turn on the computer. If everything is done correctly, you will immediately feel the result - your computer will become much quieter.

How to clean a laptop fan

Laptops are even more compact devices with high component density. At the same time, to get to the cooler, it is necessary to remove some components, which is quite difficult for an untrained person and it is best to entrust cleaning the fan to a specialist. But if you are confident in your abilities, you can try to clean the dust without removing the fan itself. To do this, you need to remove the back cover of the laptop by unscrewing several screws. Depending on the design, it may be necessary to remove some more parts.

After gaining access to the fan, you need to carefully clean its blades and housing from dust with a brush or cotton swabs. More thorough cleaning can be done using a can of compressed air or a vacuum cleaner. In this case, you must act carefully so as not to damage the heat pipes that remove heat from the laptop components. All work is necessary with the power supply disconnected from the network and the battery disconnected.

Removing dust from a laptop by removing the cooling system will be discussed in detail in one of the following articles. And recently we wrote.

How to remove a cooler from a processor— a cooler is a combination of a fan and a radiator that performs the function of air cooling the central processor in a computer. If the cooler malfunctions, the processor will quickly heat up from the power it produces, and as a result it may fail. Therefore, each user needs to be able to do it correctly, without damaging anything.

general information

Modern computers have several categories of coolers with different mounting systems. Here is a list of them:

Fixation with screws. In this case, the cooler is attached to the heatsink using special screws with a slot for a small screwdriver.

Fastening using a special locking mechanism installed on the base of the radiator. Equipment fastened in this way can be easily removed and installed. When removing it, you just need to move the latches a little to the side.

Another design of the fastening mechanism is made using a groove. Removing the cooler is also quite easy; you just need to move the lever to the side. In some fastening designs, a special clip is provided for operating with a lever, which is included with the cooler. You can also use a screwdriver.

There are types of coolers that are made monolithically with a radiator, and many do not know how to remove the cooler from the processor. In this case, you will need to remove the radiator along with the fan. As a rule, the option to dismantle this component becomes clear upon first inspection.

We advise you to perform all these actions in a free area, where you can freely manipulate the body. Don’t forget, before starting work inside the system unit, be sure to disconnect the wire from the mains power outlet! If you plan to repair a laptop, then in addition to disconnecting the power cord, you also need to remove the battery.

Instructions for performing step-by-step actions

In the case when you are doing work on a personal computer, it is advisable to position the system unit case in a horizontal plane. Since it is more convenient to work in this position and eliminates the possibility of components accidentally falling out of the slots. Be sure to remove all accumulated dust inside the case!

Now the sequence of steps when dismantling the cooler:

The first step is to disconnect the power supply wire from the fan. To do this, carefully remove the wire from the corresponding connector. In some models it is absent, since the supply voltage is supplied to the connector into which the radiator and cooler are installed.

Next, we dismantle the radiator along with the fan. Use a screwdriver to loosen the screws and set them aside. After removing the screws, grab the radiator with one hand and lightly move it left and right, and then remove the heat sink along with the fan upwards. If the fastening is made using a lever or latches, then just move them to the side and remove the radiator.

When the radiator cannot be removed, it is most likely that the heat-conducting paste on the processor has dried out due to high temperature and formed a kind of scale. It is this scale that prevents the radiator from freely separating from the processor. In order not to forcibly tear out the heatsink, but to remove it in a more gentle way, for this you need to warm the junction of the heatsink with the processor thoroughly with a hairdryer.

How to remove the cooler from the processor. Correct actions.

During the operation of a computer, a large amount of dust accumulates on its internal parts. Several operating fans (for example, on a processor, video card) ensure that dust gets into the most inaccessible places. To check the condition of the processor, update the thermal paste, or simply clean out dust, you must first remove the fan from the processor.

You will need

• Computer, small Phillips screwdriver

Instructions

The cooler is a special fan that sucks in cold air and passes it through the radiator to the processor, thereby cooling it. Without a cooler, the processor may overheat, so if it breaks, it must be replaced as soon as possible. Also, for any manipulation with the processor, the cooler and radiator will have to be removed for a while.

Today there are several types of coolers that are attached and removed in different ways. Here is their list:

Depending on the type of fastening, you may need a screwdriver with the required cross-section. Some coolers come soldered together with radiators, therefore, then you will have to disconnect the radiator. Before working with PC components, you need to disconnect it from the network, and if you have a laptop, you additionally need to remove the battery.

Step-by-step instruction

If you are working with a regular computer, then it is advisable to place the system unit in a horizontal position in order to avoid accidental “falling out” of components from the motherboard. It is also recommended to clean your computer from dust.

Follow these steps to remove the cooler:

If the cooler is soldered together with the radiator, then do the same thing, but only with the radiator. If you can't get it off, there's a risk that the thermal paste underneath has dried out. To remove the radiator you will have to heat it up. For these purposes, you can use a regular hair dryer.

As you can see, to dismantle the cooler you do not need to have any in-depth knowledge of PC design. Before turning on the computer, be sure to reinstall the cooling system.

The computer overheats, you decide to change the thermal paste. OK. but it was not there!

This article will tell you how to properly and safely remove the cooler from the processor. Trying to tear off a fan stuck to the CPU has a high chance of damaging the “heart” of your computer. How to avoid this? I'll try to describe the correct algorithm and possible situations, let's go.

How to remove a fan from a processor: algorithm of actions.

1. The computer must be completely disconnected from the network before starting. This is understandable, another matter: is it worth waiting for it to cool completely?

Allow the radiator to cool - opinions differ.

On the one hand, this is true: the CPU can heat up to 90 degrees, you will burn your hands. But at high temperatures, the thermal paste that is located between the processor and the fan more pliable; in other words, in a dry state, the process of removing the cooler can become a real problem. But this does not work for all types of thermal pastes. It won’t work with KPT-8: it’s pasty at any temperature.

I advise you to remove the fan when the radiator has not yet completely cooled down. When you touch it, your hand will feel warm, but not hot.

2. Turn off the power to the cooler.

To do this, pull the plug strictly vertically.

Any loosening is unacceptable. You will break the needle.

3. Remove the fan mount.

The type of fastener depends on the motherboard and each specific device. Some computers use brackets, others use latches of some kind. At first, this seems like a problem, but in fact it’s nothing too complicated.

If there are bolts, they should be unscrewed against clockwise.

4. Above was the prelude, now let's do the action itself. When everything is disconnected, pull out the cooler with the radiator. And then they will come. PROBLEMS.

There is a 90% chance that the CPU is literally stuck to the cooling. Because of thermal paste. Be extremely careful: shake it up and down, left and right, clockwise, etc. Gradually increase strength and amplitude. It is forbidden to rush or immediately show excessive efforts.

Don't be surprised or scared if you pull the processor out of its original socket along with the cooling.

P.S. turning on a computer without a fan will kill the processor. With a guarantee and a control shot. Do not do it this way. Also, don’t be lazy before assembling, good luck!
