How to replace thermal paste: simple instructions that will extend the life of your PC. How to change thermal paste on an asus laptop. How to correctly change thermal paste on a laptop How to change thermal paste on a laptop

Despite its small dimensions, the processor is, one might say, the heart personal computer and it should work properly. But, performing hundreds of operations per second, the processor is very heats up because of which it can fail, simply by burning out. It is to prevent such a situation and need thermoplastic, which is an additional cooling element.

So, thermoplastic is substance, which is applied thin layer on the processor for better heat dissipation.

Most of cooling takes over cooler And ventilation, since they are capable of cooling even the hottest processor in less than 15 seconds, and thermoplastic is needed only for improvements coupling of the cooling element with the device.

Many users ask the question: Why change the paste at all? Over time, its layer dries up and it performs its functions less and less effectively. As you already understand, the absence of a protective layer leads to overheating, which in turn will cause unstable work myself operating system(OS is trying limit performance in order to lower temperature of the hardware of the personal computer), and also tries to protect the entire hardware of the PC, since the processor, along with other elements, can burn out. Therefore, periodically, but still recommended replace thermal paste.

In addition, you need to choose the right pasta. The best products with heat-dissipating elements (for example, silver), which several times improve the process of heat exchange between PC elements. When applying such a paste, you get a thin layer of the substance itself and an additional layer of silver, which removes heat.

How to apply thermal paste correctly

High-quality cooling directly depends on the correct application of the paste. The slightest flaws will significantly reduce the cooling efficiency of even the most powerful system. Basic principles are:

Not worth it remove the radiator after installation to check whether the thermal paste is evenly distributed. Thus, you will disrupt the adhesion of the surfaces and will have to start the process all over again, completely removing the already applied layer.

Replacing thermal paste on the processor

Before you start replacing the paste, you must purchase it. Costs about 150 rubles per tube. Well, now, you can get started:

Changing thermal paste on the video card

The essence of replacing the paste on a video card is as follows:

Replacing thermal paste on a laptop

Replacing thermal paste on a laptop with almost nothing no different in replacement on a personal computer. The only thing worth noting is that the hardware elements on the laptop will be placed differently (the type of arrangement of the elements depends directly on the laptop model and manufacturer). But, as a rule, each element of the device is located in a special cell and is easy to get for subsequent processing.

It is safe to say that any laptop owner has at least once wondered: “Why is the laptop so noisy?” Indeed, now even a child knows that there are electronic boards inside a computer and laptop. But the operation of the electronics is absolutely silent!

In fact, everything is simple - it is not the electronic components that make noise, but the systems active cooling, removing heat from the heating elements of the laptop. During operation, the metal fins of radiators and fan blades become covered with a layer of dust, which significantly worsens temperature regime. Logic circuits increase the speed of rotation of the fan blades (hence the increase, but even this does not provide effective heat removal - the laptop requires an immediate revision. It would seem that it is enough to clean the cooling systems and the laptop will work like new. Unfortunately, as with everything, there are some peculiarities, without knowledge of which, self-cleaning may not bring the desired results. One of them is replacing the thermal paste in the laptop.

Thermal paste is a special plastic mixture, a thin layer of which is applied as an intermediate thermal interface between the heating element and the metal radiator. Her distinctive feature is high thermal conductivity, that is, in fact, its presence does not impair the transfer of heat from the microcircuits to the radiators. Thanks to the use of thermal paste, it is possible to neutralize the influence of possible errors in the processing of contacting surfaces: when applied, it fills all irregularities, thereby ensuring ideal contact and heat transfer. on a laptop is to update the factory thermal paste with a new one. The internal structure of a personal computer and a laptop are similar, so thermal paste for a laptop and thermal paste for a computer are one and the same. Manufacturers offer a wide selection of thermal pastes, the composition of which is usually kept secret. Here are just a few of them: the usual Soviet-era paste KPT-8 based on an organic silicon compound; Silver from Gigabyte with silver particles; Arctic Silver with ceramic inclusions, which retains its characteristics even at sub-zero temperatures (the favorite thermal paste of overclockers), etc.

Replacing the thermal paste in a laptop is necessary if cleaning the cooling system from dust does not improve performance. It is impossible to definitely indicate what temperature is normal, because it depends on a number of factors: the design features of the laptop, its internal components, the type of programs, and operating conditions. The need to update the thermal paste can be determined by an indirect sign: the laptop makes a lot of noise and heats up even in “light” programs, such as browsing the Internet or reading texts. In this case, replacing the thermal paste in your laptop can help.

Any service center will be happy to take on this work, because its cost is quite high. If you are short on funds or want to repair your own electronic assistant, then you should first make sure that the laptop is running out. The fact is that opening the case yourself will void the warranty. So, replacing thermal paste in a laptop begins with removing the bottom cover of the case, which provides access to the cooling system. We carefully examine the internal structure: many modern laptops use heat pipes, so you should dismantle them without haste. Usually no difficulties arise; the main thing is to remember the original location. After removing the locks (if any) and unscrewing the screws, remove the heat pipe. A little effort may be required, as due to constant heating, the factory thermal paste dries out and sticks the chips to the radiators. Remove the old thermal paste and apply a thin layer of new in its place. Then we assemble everything in reverse order.

If you don’t take care of your equipment, sooner or later it will break down, everyone knows about it. A laptop is no exception: after some time it needs to be cleaned, dust removed and internal components put in order, otherwise the device will begin to overheat and slow down. What should be the proper way to clean a laptop and replace thermal paste? Let's take a closer look.

Along with scheduled cleaning, preventative maintenance of the cooling system is carried out.

Cooling methods

There are several methods to reduce the heating of a video card. The most popular is the purchase of a special stand. According to experts, it does not help matters much - the temperature drops by 2-4 degrees at most. Another method is to update the video card firmware (BIOS). Only specialists are allowed to use this option, because in the absence of certain knowledge, the video chip can be permanently disabled.

An alternative to the methods described above is replacing the thermal paste between the heatsink and the chip. With the help of a special substance you can reduce the temperature to 11 degrees!

The purpose of thermal paste is to conduct heat between the heatsink and the chip, compensating for the unevenness of both surfaces.

Preparing for replacement

To replace thermal paste correctly, you will need the following materials:

stationery knife;
thermal paste. You can purchase KPT-8, it is considered the cheapest. There is no significant difference in the choice of brand, the quality does not change much. You can buy thermal paste at almost any computer store;
toilet paper or napkins. The processor and chip will need to be cleaned. In addition, napkins can be used to wipe your hands.

Execution steps

The first step is to unscrew and remove the back cover of the device. It is important to understand that this will void your laptop's warranty. Disconnect the device from the power supply, remove the battery and unscrew the bolts. Try not to lose the bolts so that after the procedure you can return everything to its place.

Removing the cover, you will see all the “insides” of the laptop. What interests us most is the video card. In most cases, developers screw it with 4 bolts, pressing it to the radiator. Unscrew the bolts and carefully pull this component out of the connector.

The next step is to clean the chip and heatsink from old thermal paste. Experienced users say that if thermal paste is applied incorrectly, the opposite effect can be achieved. As you can see, this is not a case where you can’t spoil the porridge with honey. The product must be applied to a previously cleaned, degreased surface (use a utility knife to remove old material).

If you want to do everything correctly, do not overdo it with the amount of thermal paste. For application, you can use any available product. Computer parts stores may offer a special spatula, but in practice you can do it with your finger. The product is applied exclusively to the chip, and the layer must be quite thin. It is advisable to rub it evenly over the surface, without going beyond the edges of this element.

To prevent devices from overheating, it is advisable to get rid of dust accumulated inside during use. Gently brush the parts of the laptop to remove dust. It is this that is the main enemy of technology: by getting into cracks and corners, it prevents the coolers from spinning and cooling the device.

Reassemble the laptop in reverse order:

screw the video card back to the radiator;
install the back cover;
connect the device to power.

A couple of days ago I decided to change the thermal paste in my laptop, and there were several prerequisites for this:
1st last time The thermal paste was replaced more than a year ago,
2nd in critical operating modes, the processor temperature reached 100 0 C.

Despite the fact that I know the maximum permissible temperature of my processor - it is 105 0C, I did not wait until it starts to turn off, reduce operating frequencies, or simply burn out.

The first thing I would like to say to those who are going to change the thermal paste on their own is to think about whether it’s worth it, that’s what I mean - replacing thermal paste is not the most difficult process, but disassembling a laptop is another matter - if a person is not sure, what does he do or, as they say, “your hands don’t grow from there” - it’s better to give it to specialists, it will come out cheaper

As for desktop PCs, things are simpler there. Of course, crooked hands and heads can do something bad, but the probability is much less. Enough preface - let's get started.

1. Before disassembling the laptop, I went online and found a video showing how my laptop was disassembled. On at the moment The vast majority of models are freely available, so this should not be a problem.

2.After I knew exactly what to disassemble and why, I got to work. In this matter, the main thing is not to rush, carefully, slowly and everything will work out for you. A few tips - put bolts and other parts of the laptop in different places, so that when the time comes to assemble, you don’t end up with one big pile of parts and different bolts, and you just don’t remember what goes where and why! But put thermal paste either on the battery or in the sun - why? The higher its temperature, the easier and more evenly it will be applied to the surface of the processor. By the time you disassemble your laptop or computer, it will already be warm enough.

3. Disconnect all connectors and cables very carefully, there is no need to put any effort there, everything can be removed quite easily.

4. In order to clean the cooler, you will most likely have to remove it. Often it comes complete with a cooling system. There is one point here: the cooling system bolts must be unscrewed sequentially, from larger to smaller numbers, for example: 6,5,4,3….. The thermal paste may have dried a little to the surface of the processor and video card, so you need to carefully disconnect the cooling system from the laptop.

5. Clean the cooling system. A brush and a vacuum cleaner are best for this. My laptop was used in fairly harsh conditions, but it always worked in clean rooms and only on clean surfaces, and even this is enough for the cooling system to be covered in dust.

6. After the entire system has been removed, it is necessary to clean the surface on the processor and cooling radiator. It is best to use cotton wool and alcohol; you can carefully remove the layer of old paste with a plastic card, but in no case with metal objects - you can damage the processor!!! It is necessary to clean until the surface becomes perfectly clean and smooth.

7.Now we apply a layer of new thermal paste, it should be quite thin and uniform, no thicker than 0.5 mm. (ideally even less, but this is quite difficult to achieve). You should not apply one large drop in the middle of the area, and then press it down by tightening the bolts on the radiator - with this installation method (if the thermal paste is thick) you will not get a uniform layer.

8.Next, put the cooling radiator in place and tighten the bolts, now in the correct sequence, i.e. 1,2,3,4,5...... You are putting the entire laptop back together, the main thing is not to break anything and do not forget to connect all the contacts and cables. That's probably all, nothing complicated.

If the laptop is many years old, or for some reason the CPU begins to heat up very quickly to a critical temperature under light load, then this is a serious reason to check the condition of the thermal paste. This material is present between the processor itself and the device that removes the heat generated during operation - a radiator, complete with a cooler.

What is thermal paste

Thermal paste is a special multicomponent composition with high thermal conductivity. It is much higher than that of air, which allows thermal paste to cool the CPU extremely effectively - which is exactly what it is needed for. Its use is necessary to maintain normal temperature conditions during PC operation.

The composition is applied when assembling a computer. Its disadvantage is that with very long use it begins to lose its properties necessary for normal operation processor. Which, accordingly, leads to the need to replace it. When choosing paste for your CPU in a store, you should choose products from well-known brands.

Choosing pasta

Today, specialized stores offer the composition of the type in question from the most different manufacturers. Choosing the best one among all this variety is quite difficult.

In terms of their performance characteristics, all of the above products are similar, only the price differs, as well as the quantity in one package. When tested on identical equipment, the results of all formulations are practically the same.

Thermal paste of domestic origin called AlSil-3 and KPT-8 is especially easy to apply. Its advantage is that its consistency is liquid enough to be evenly distributed over the surface, and also viscous enough not to spread. Removing it is simple: just wipe it over the surface with a dry cloth. Therefore, the choice should be made on these compounds.

General information on replacement

Replacing the type of composition in question involves completely disassembling the computer. Which, accordingly, entails a complete loss of warranty: free repairs at the service center will not be possible. Therefore, if problems arise in the operation of the CPU, you should not immediately disassemble the PC case. Maybe, the best option will take your laptop to a specialized service center.

It is important to remember that some pastes are made on the basis of metal chips, which are a good conductor. Therefore, it is necessary to carry out the replacement as carefully as possible, preferably using a thin plastic card, without smearing it on the tracks and electronic components. Short circuit may lead to failure of the motherboard or other important details PC.

Changing thermal paste on a laptop processor

Replacing the heat dissipation composition on the computer CPU should be done as carefully as possible. Since there is always a chance of damaging something with one careless movement. This will lead to quite unpleasant consequences. It is necessary to prepare everything you need in advance.

Video: Thermal paste test

What is needed

To carry out the operation in question, the following items and materials will be required:

thermal paste;
dry soft cloth or rag;
stationery knife;
Phillips screwdriver with a thin tip;
slotted screwdriver;
thermal paste;
vacuum cleaner or fan.

All of the items listed above must be prepared in advance. Since it is advisable not to interrupt the process of disassembling the laptop. If the implementer this operation does not carry out repairs professionally, there is always a possibility of forgetting the sequence of its implementation. As a result, extra bolts and parts may remain, which is extremely undesirable.

It is very important to choose a soft napkin. It will be needed to remove old material and carefully remove excess new material. The use of wipes with abrasive properties is excluded. The presence of scratches will make heat dissipation ineffective. You should also avoid using rags that have a large number of pellets and other large particles - they also impair heat transfer.

Disassembly

Replacing thermal paste on a laptop processor begins with disassembling the computer case. This stage is the least responsible, but the longest. And yet, when implementing it, you must be as careful and careful as possible.

First of all, it is necessary to thoroughly clean the device from dust and other foreign matter that accumulates inside the case over time.

This is done as follows:

Cleaning surfaces

It is very important to remove the old one before using new thermal paste. Since its presence can significantly reduce thermal conductivity. This will negatively affect the operation of the laptop. Removal is carried out with a regular napkin if the remaining composition is sufficiently liquid.

If for some reason it is not possible to clean the surface of the radiator and chip with a napkin, you can use other methods:

using a screwdriver;
using an eraser;
alcohol

The use of a screwdriver is highly undesirable, since there is always a possibility that it will come off and damage any of the “insides” of the PC - this is unacceptable. This cleaning method should be used only in particularly difficult situations and only when removing paste from the radiator.

A much simpler and safer method is to dissolve heavily hardened paste with alcohol. It is only important to perform this action extremely carefully. After performing such an operation, it is necessary to thoroughly dry the motherboard and other surfaces where liquid could somehow get into.

A regular stationery eraser like Koh-I-Nor, white, will make it possible to cope even with very old and dense paste.

Applying paste

The paste should be applied in an even layer, its thickness measured only a few microns. A high-quality composition of this type must have good viscosity - this will allow it to take the required shape. Application must be made with a clean plastic card or something similar.

Under no circumstances should you apply the paste with your finger: even on clean hands there is always some amount of oil. It has very poor thermal conductivity; its presence can negatively affect the temperature of the CPU.

The action in question is performed in two stages:

Ultimately, the already applied layer should have as smooth a surface as possible.

Assembly

It is very important to correctly install the cooling radiator, which receives heat from the heated central processor. Upon contact, you must ensure that the thermal paste is not squeezed out - this happens when applying an excessively thick layer.

It is important to avoid getting various foreign objects, especially those that conduct electricity, into the housing.

Next, you should carefully reinstall all previously removed parts, observing the sequence. All bolts should be carefully tightened, but not overtightened - this can lead to damage to the housing, which is extremely undesirable.

You can find out what thermal paste is needed for a specific processor on the manufacturer’s website. Most often, specific recommendations are given there for replacement, as well as for choosing the composition. All kinds of tests and tests are carried out in production. This allows engineers to recommend a specific brand of thermal paste.

The presence of lumps and other foreign inclusions in the layer applied to the surface of the CPU and radiator must be completely eliminated. Otherwise, this may lead to the formation of air layers, which will definitely impair thermal conductivity. If they are available, it is better to replace the material used with some other one.

Using high-quality material as a layer between the CPU chip and the cooling system allows you to extend its service life and ensure normal temperature conditions. This opens up great opportunities for overclocking. Monitoring the condition of the thermal paste is mandatory, because if it dries out, the CPU may simply fail.

This happened a little less than two...

When the thermal paste dries out, the user is faced with incorrect operation of the computer. Basically, these are device freezes, unauthorized shutdowns, and noticeable heating of the case. The reason is that thermal paste, which has lost its properties, begins to weakly transfer heat from the microcircuit operating under load to the cooling plate. Orders for paste replacement are accepted around the clock by phone or via the website. The operator will tell you how much it costs to replace the laptop’s thermal paste and fill out a request for a courier or technician to come out. Which employee will respond to the call depends on the computer problems encountered by the customer.

Instructions for replacing laptop thermal paste

To apply thermal paste, you will need certain skills because this seemingly simple process has a number of nuances, failure to comply with which can cause harm to the device. So, what does a user who orders a thermal paste replacement get from our service center:

free delivery of a faulty computer is carried out before and after repair, and when it is only necessary to replace the paste, the technician will come to the customer’s home and thereby save the client time;
during disassembly of the computer, cables and case fastenings will not be damaged, and the central processor or socket itself will not be damaged as a result of unprofessional actions (which often happens when trying to apply the paste yourself);
Removing dried paste is a procedure during which both the processor and the radiator can be damaged, but the client does not have to worry about the quality of the result because our service employs professionals;
thermal paste is applied in a thin layer, and failure to comply with this rule is a common mistake - as a result, the heat transfer from the working processor to the radiator deteriorates and the computer overheats;

Replacing the thermal paste in a laptop is a common activity that will help maintain its performance and service life.

Oddly enough, overheating and ventilation problems are the most common problems, which, in turn, will limit the functionality of your computer. So, in order not to experience all these consequences on your own laptop, you should do one of the following:

disassemble the device, remove the motherboard, clean the case, etc. Dust constantly gets on important elements, causing serious problems with heat transfer inside the laptop. You can get more information about cleaning your laptop from dust by reading the article ""
Buy a cooling pad at a computer store. This device will provide additional cooling.
look deeper and check the thermal paste on the processor. Replacing the thermal paste in a laptop is another effective measure that can affect performance.

Today I will tell you how to properly change the thermal paste in a laptop without damaging its vital parts.

Attention! It should be remembered that assembling and disassembling the laptop case will deprive you of warranty benefits from the manufacturer. Thus, service centers will not repair your “patient” for free. You will perform all these manipulations at your own peril and risk. And if you have never dealt with such equipment, then it is better to trust specialists or friends who have enough knowledge in this area.

What will you need?

As you may have guessed, without thermal paste, our operation will not even begin. One tube of this paste costs about $10. The Titan Nano Grease brand performed well. If you decide to buy thermal paste on the regular electronics market, then be careful or visit a specialized store. Remember that such places are full of fakes, including domestic brands, for example KPT8 (the original KPT 8 thermal paste is very good). Replacing thermal paste in a laptop should be done with trusted brands, since “cheap” names, or even worse, fakes, may not be intended for their purposes at all. (I learned from my own experience)

And of course, you will need to disassemble the case. To do this, arm yourself with a screwdriver and dry wipes in order to simultaneously clean the board from dust.

Let's start the operation.

Before disassembling the case, do not forget to remove the battery and disconnect the power supply. I also recommend covering the desktop with some kind of cloth so as not to damage the plastic cover with scratches. When unscrewing the bolts, be careful, do not forget to make sure that not a single screw is left on the body. Otherwise, the plastic may crack and the body will break. Well, if you don’t know how to disassemble your particular model, then use the help of Google or Yandex. can also be provided in the technical manual.

After you have removed the housing cover, you need to find. Laptop thermal paste is replaced there.

Using a pre-prepared cloth or dry wipes, clean the radiator of dried thermal paste. The paste must also be removed from the chips. Don't be alarmed if the hardened paste resists your efforts. You can get rid of it using plastic card. In this case, you must be extremely careful, try not to damage the microcircuits.
