How to properly install copper laptop gaskets. How to choose thermal paste and what will it get you? Without knowing the parameters

Overheating of internal parts is dangerous for any equipment. This is especially true for PCs and laptops, in which processors and video cards are often coated with special thermal paste. Thermal pads are often installed. They fill the space between the heatsink of the cooler and the chip, which also helps to improve heat transfer. At the same time, many users have a question: "What is better - thermal paste or thermal pad?" Let's try to figure it out.

First, let's talk about thermal paste. It is a multicomponent thick-like (sticky and plastic) substance with high thermal conductivity. It contains various synthetic or mineral oils, metal powders, oxides, etc. Thermal grease is the most common material that is used to properly cool electronics.

As for the functions of thermal paste, they are as follows:

Filling the void between the processor / video card and the cooler radiator (due to which an important part may overheat);
Providing heat transfer from the processor to the cooling system.

The disadvantage of thermal paste is that during operation it dries up and loses its properties. Therefore, it is advisable to replace it for prophylaxis at least once every 6-12 months. Unfortunately, many users ignore this. As a result, their PC or laptop crashes due to overheating.

However, despite all this, computer manufacturers continue to actively use thermal grease to protect processors and video cards from overheating. Although now there are many other thermal interfaces. For example, the most popular alternative to thermal paste is thermal pad.

What is thermal pad?

On the Internet, you can find a variety of names for this thermal interface - thermo gum, chewing gum, hot melt glue, thermal rubber, etc. The thermal pad is also used to cool important PC parts, which are characterized by high temperature operating conditions. What is it? In fact, it is a thin elastic sheet consisting of a base and a filler (graphite or ceramic).

At the same time, the modern market offers several types of thermal pads at once. They differ from each other as follows:

thermal conductivity;
thickness (as a rule, it varies from 0.5 mm to 5 mm);
"Design" (we are talking about the fact that the thermal pad can be single-layer or double-layer, as well as have both one and two adhesive surfaces);
material (rubber, silicone, copper, ceramics, aluminum; there are also home-made options - for example, from a bandage impregnated with thermal paste).

So if you decide to put a thermal pad or just change the old one to a new one, then be sure to take into account its thickness, thermal conductivity coefficient, and other characteristics.

Also pay attention to the production date. If the thermal pad was released more than a year ago, then you should not use it.

What should you choose?

Let's try to answer the question, which is better for a laptop or PC? Thermal paste or thermal pad? Let's analyze the points:

Let's start with the fact that in terms of its effectiveness, the thermal pad is inferior to paste, if the distance between the part and the cooling system is minimal. For example, literally 0.2-0.3 mm. If the distance is close to 1 mm, then thermal paste cannot be used. Otherwise, overheating is ensured.
The thermal pad shows itself well if it is used in devices where the seats of the chip and the cooling radiator are removed from each other (more than 0.5 mm). After all, if we take thermal paste here, then there will be no sense from it. Due to the thick layer, a very low heat dissipation rate will appear. The processor or video card will start to get very hot.
Replacing a thermal pad is often easier than applying a new thermal paste, which requires both cleaning from the old paste, and a thin uniform layer, and even special tools... However, replacing the thermal pad on a processor or video card is not always easy. It is necessary to select it correctly in size, take into account the thickness, the degree of compression (it should not be more than 70%, otherwise, due to strong deformation, it will lose most of its heat-conducting properties) and many others. dr.
Price. This criterion will not allow us to find out which is better. Since the cost of thermal paste and thermal pad is about the same. The cheapest options for such thermal interfaces will cost you 100-150 rubles. However, we do not recommend saving. It is advisable to choose products whose cost exceeds 300 rubles.
Life time. Much depends on the quality of the thermal paste or thermal pad. Although, on average, the latter serves a little more. True, if for some reason you need to remove the cooler radiator from the video card or chip, then you will have to change both the thermal paste and the thermal pad.
On average, in terms of thermal conductivity, thermal pads are inferior to thermal pastes, the best samples of which have indicators at the level of 8-10 W / mK. Thermal pads cannot have such values. They have a lower thermal conductivity coefficient. On the other hand, there are also thermal pastes with a thermal conductivity of 1-2 W / mK. In most cases, they will already be inferior to thermal pads.

It turns out that each option has its pros and cons. Therefore, it is impossible to say unequivocally which is better and which is worse. Experts recommend the following:

For laptops and netbooks, use a thermal pad. They argue that the processor and video chip in such devices get hotter. Apart from this, a laptop or netbook generally does not stand in one place. They take him with them to work, study or visit, which means that he is often shaken. In such conditions, a good and high-quality thermal pad will be more practical and reliable. Therefore, it is better to choose it instead of thermal paste.
PC owners should give preference to thermal pastes. Indeed, on most models, the gap between the processor and the cooler heatsink is minimal. It is difficult to fit even a thin aluminum or copper plate here.

Remember! If you change the thermal interface yourself (for the same laptop), then the thickness of the new thermal pad should be slightly larger (about half a millimeter) than the previous one. The fact is that during operation it shrinks a little. In addition, if you are not sure how thick the thermal pad is suitable for your PC or laptop model, then take 1 mm. This is the most common and standard gap between a heatsink and a chip for many devices from a wide variety of manufacturers.

Can thermal paste be replaced with a thermal pad (and vice versa)?

In theory, replacing the thermal paste with a thermal pad is possible. True, in practice this is not always recommended. This is explained by the fact that in most cases, replacing thermal paste with a thermal pad and vice versa leads to an increase in the temperature of the processor or video card. Why? Let's break it down with a few examples:

If you remove the thermal pad and apply paste instead, it is likely that the heatsink of the cooler will no longer fit snugly against the processor, or graphics adapter... The fact is that most thermal pads are much thicker than the acceptable thermal paste layer. Air will begin to enter this free space, which does not conduct heat well, contributing to overheating of the device.
If, on the contrary, instead of thermal paste, install a thermal pad, then the pressure on the springs and bolts that hold the entire structure of the cooling system will increase. That is why it can fail at all or work unstable.

Therefore, it is not recommended to change the thermal paste to a thermal pad or vice versa. Use the same thermal interface as before. That is, if the manufacturer has applied thermal paste between the processor and the cooler, do the same, giving preference to this heat-conducting substance. It's not worth the risk.

Remember not to apply thermal paste to the thermal pad or vice versa. Such a "neighborhood" will only have a negative impact and worsen thermal conductivity. What is the threat? Failure of the video card, breakdown of the motherboard or processor.

We have already written above that if you are not sure which gasket to take on your processor or video card model, then give preference to a product with a thickness of 1 mm. This is the standard gap between the chip and the cooler heatsink on most devices.
It is also not scary if the thermal pad is thicker. For example, 1 mm instead of 0.5 mm. But only on condition that bolts are used as fastening, which will press the radiator tightly enough. As a result, you will get the same 0.5 mm at the junction. So if we are talking about replacing the thermal pad, it is better to take a thicker one than a thinner one.
In no case should you save money both when choosing thermal paste and gaskets. Too much depends on this material. In addition, due to the use of low-quality thermal interfaces, you can "get" to repair or replace expensive components.
Despite the good thermal conductivity of copper gaskets, they must be applied with care. The fact is that copper does not differ in ductility and flexibility. Therefore, if the surface of the radiator is uneven, then a gap may appear between it and the processor or video card, into which air can enter. All this will lead to excessive heating of the part.

One of the reasons for electronic chips malfunctioning is overheating. It leads not only to errors in the operation of equipment, but also to the degradation of elements, significantly reducing their service life.

The use of cooling radiators helps to avoid overheating of the video card or processor. But for normal heat transfer from the chip to the radiator, the empty air space between them is necessarily filled with a thermal interface - a layer of substance characterized by high thermal conductivity. Air has low thermal conductivity - 0.022 W / m * K, and, for example, thermal paste KPT-8 - 0.7 W / m * K.

Thermal paste

Heat transferring paste is thick, similar in consistency to toothpaste, multicomponent substance. It contains various mineral, synthetic and metal components. It is the most common material for proper cooling of any electronics.

The paste has several functions:

Fills micro gaps between the chip and the heatsink.
Improves heat transfer parameters.

Thermal pad

The thermal spacer is a plate of heat-conducting material that is placed between the heating element and the cooling system.

Gaskets differ by:

Thermal conductivity.
Material (ceramic, silicone, rubber, metal such as copper or aluminum)
Thickness (0.5 to 5 mm)
The number of layers or adhesive surfaces.

It is not worth buying, much less using gaskets produced a year or more ago.

What common

Price. The price of thermal paste and thermal pad of the same class is approximately the same. The main thing is not to save money, but to take the product that is most suitable for your laptop. Otherwise, the saved hundred rubles can result in expensive repairs, both of individual computer components and of the entire device.
Replacing one interface with another. Not recommended. Usually, this action leads to a minimum increase in the temperature of the chip. For example, the entire processor cooling design can be designed for a certain distance between the chip and the cooler. If the system was initially in equilibrium using a thermal pad, then replacing it with thermal paste will lead not only to a worse fit between the heatsink and the processor, but also to loosening of the cooling system mounts.
Possibility of simultaneous use. In most cases this action does not make sense, since it leads to a deterioration in thermal conductivity. The only option for the simultaneous use of thermal pad and heat transfer paste is when the pad is metal plate... Then the paste is needed to fill the gaps between the plate, chip, radiator.

Differences

Life time. Depends on the quality of the thermal interface. But on average, pads live slightly longer than pastes. If for any reason it was necessary to remove the cooling system from a chip or video card, then any thermal interface must be replaced.
Thermal conductivity. In most cases, pastes have a higher thermal conductivity than gaskets. The best representatives of thermal pastes have thermal conductivity from 10-19 W / m * K and up to 80 W / m * K in the case of pastes based on liquid metal. Thermal pads have lower coefficients - 6-8 W / m * K. Therefore, it is better to use thermal grease with top-end processors or video cards.
Ease of use... Replacing the thermal pad is much easier than replacing thermal grease. It is enough to remove the old thermal interface, make the necessary measurements, cut it off, and then glue the new one. The gasket can be cut to a comfortable shape or glued in two layers. Unlike paste, it does not get dirty. To replace the paste, you need not only a pre-cleaned surface, but also often additional tools - a plastic card or a brush. Also, from the first try, it is more difficult for an inexperienced user to determine the right amount of paste.

What and when to use

Gaskets and pastes can be both bad and good quality, and therefore it is incorrect to compare a good gasket with a bad paste, and vice versa.

If we compare interfaces of the same quality, then a thermal pad is most often suitable for a laptop. But it must be with high thermal conductivity, since due to the design features, the processor and video card in a laptop get hotter than in a PC. Due to its shock-absorbing properties, a good gasket softens the harsh operating conditions of the device: constant transfers from place to place, shaking and vibration, change of position from horizontal to vertical.

An important factor when choosing a thermal interface is the distance between the heat generating component and the heat removal device. For example, if the gap between the processor and the heatsink does not exceed 0.3 mm, then pasta is the best option. But already at 0.5 mm and more, its efficiency decreases. Firstly, a too thick layer of paste conducts heat worse, and secondly, it can spread over the surface of the board. All this can lead to breakdown - fire. In this case, the use of a thermal pad becomes optimal.

The use of thermal spacers is also justified when only one radiator is used to remove heat from the cooled elements. Usually, the chips on the board have different heights, and the spacer, due to the compressibility, is able to smooth out this difference. Thus, normal heat dissipation is ensured for all elements. Heat-conducting paste in this situation is not only ineffective, but even harmful.

Do not contradict the intention of the manufacturer. If the laptop originally uses thermal grease, do not replace it with a gasket, and vice versa.

In order for the laptop to serve for a long time, you must remember to regularly change all of its thermal interfaces. It is also useful to know the operating temperatures of the main vital parts of the device, because the correct temperature regime is the key to a long, trouble-free service of the device. And programs such as Everest or Aida 64.

The thermal interface in the cooling of PC components and other electronics plays no less, and sometimes even a greater role than the type, size and design features of the cooling system itself. The use of a poor-quality thermal interface can negate all efforts to reduce temperatures (a typical and most striking example is central processors, in which thermal paste is located not only ON the heat spreader cover, but also directly UNDER it).

But the opposite is also true: an effective thermal interface is able to "bring down" the temperature of the cooled element, playing from one or two to a dozen degrees, which will extend the life of the device, exclude possible malfunctions due to overheating and reduce the noise emitted by the cooling system.

That is why it is not worth saving on the thermal interface, as well as approaching its choice according to the principle "I take the first thing I come across". Thermal paste is far from the most expensive commodity, but the viability of much more important components depends on it.

What should you look for when choosing?

Thermal interface type

In the CSN catalog, in addition to traditional plastic thermal interfaces, other varieties are presented that have their own purpose and their specific application. Before choosing a specific composition, you should decide what exactly you are going to cool, and in what way.

Liquid metal. It can be presented both in direct liquid form and in the form of gaskets, which must be heated and melted between the cooling system and the cooled element before use. In both cases, this type of thermal interface has the best thermal conductivity, and also feels great at near-zero and sub-zero temperatures, which makes it an excellent option for extreme overclocking.

The disadvantages of liquid metal are not only its high cost. First of all, it is an extremely aggressive composition - for example, ZhM cannot be used with aluminum coolers , as aluminum under its influence dissolves in the most natural way. For the same reason, the LM can easily make the processor cover unusable, which will deprive the owner of the CPU of the warranty. In addition, liquid metal is conductive, and its use on crystals without a heat-distribution cover - for example, on graphics chips of video cards - is not recommended.

Thermal pads... Flexible and versatile thermal interface designed for cooling those units where too high efficiency is not required. Unlike liquid metal, it is an electrical insulator, which allows you to cover both the cooled element and the board space around it with a gasket without unnecessary meticulousness. A typical example is cooling VRM video cards and motherboards equipped with a suitable radiator.

The main advantage of a thermal pad is its elasticity and the ability to fill any voids, while retaining the ability to conduct heat. This property is extremely important if the cooled elements are at different heights - for example, the memory chips of a video card relative to the graphics chip - or have a complex relief.
But it is impossible to use thermal spacers on the CPU or GPU - their efficiency is too low to provide proper cooling to these nodes.

Thermal paste as it is - the composition is almost universal. It does not conduct heat as efficiently as liquid metal and requires minimal clearance between the element being cooled and the cooling system for efficient heat transfer. But at the same time, it does not conduct current (the exception here is pastes with metal particles) and is many times superior to thermal pads in terms of efficiency.

Accordingly, thermal paste in its traditional sense can be used almost anywhere. The only question remains in choosing an interface with suitable characteristics.

Hot glue differs from thermal paste in that it retains plasticity only for a limited time after application to the surface. Subsequently, the glue sets and forms an extremely strong bond that can support the weight of the radiator or other element without additional fixation. As a result, hot melt glue is ideal, for example, for fixing VRM radiators of motherboards and video cards, where screw fastening of the corresponding elements is not initially provided.
The disadvantage of hot melt glue is quite obvious: the fixing strength does not make it easy to dismantle the radiator from the cooled element. Moreover: during the removal process there is a considerable risk of tearing the element off the board. Therefore, use a hot melt adhesive for the CPU and GPUs also not recommended.

Efficiency

Unfortunately, the most important parameter of the thermal interface cannot be found either in store catalogs or on the websites of manufacturing companies. Some, of course, are inclined to associate the efficiency of the thermal interface with such a parameter as thermal conductivity- all manufacturers just indicate it.

However, in reality this is not entirely true. As tests on real iron show, it is far from always that a paste with a higher thermal conductivity is more effective than a paste with a lower thermal conductivity. Often, one and a half or even a twofold difference in the passport parameters ultimately results in practically the same temperature results.

It is necessary to choose thermal paste according to one criterion: the results that it demonstrates in professional reviews from reputable publications. As a rule, there is ensured both uniformity of testing conditions and a competent methodology for conducting tests, which makes it possible to call the results obtained as reliable.

Having on hand a database of results demonstrated by different pastes on the same gland under the same conditions, it will be possible to make a reasoned and rational choice. For example, if a certain CPU when using paste A, it warmed up only to 84 degrees, and with paste B - up to as much as 96 degrees - it is immediately clear who is better here. If, when using pastes A, B and C, the temperature is the same, but the price and dispensed volume of pastes differ significantly, choose the most profitable option.

Package

Paradoxically, but yes - this is also very important point... Typically, thermal grease (and other interfaces) are sold in more quantities than are needed for a single use. This is convenient if you do not want to go to the store every time you change the processor cooler or clean the laptop, but the issue of storing the thermal interface is automatically raised.

V sachets either small quantities of thermal grease (1 gram) or thermal pads are offered. In both cases, this is not the most convenient option - the remains of the thermal paste "in the fresh air" will quickly dry out, and the impregnation will evaporate from the thermal pads. Therefore, when purchasing such a package, you should immediately calculate the amount of thermal interface you need, or take care of its storage.

Jars, bottles and tubes- a more reliable option, thermal paste in such packages can retain its properties for literally years, without drying out or decomposing into components. The only drawback of such packaging is not very convenient dosage and application.

Syringe- ideal, and therefore the most common option. It is hermetically sealed, but in addition, it is extremely convenient for dosing and applying the paste to the cooled surface.

The volume of thermal paste and the number of thermal pads

It is also an important factor, since the final purchase price and issues of further storage of the thermal interface depend on it. So, if you just need to carry out a one-time prophylaxis of your PC, laptop or other device - 1-2 grams thermal paste and one thermal spacers are enough for this. It would be better even to purchase a smaller amount of thermal interface, but choose a composition with better characteristics.

And do not convince yourself that you are taking the thermal interface "in reserve". Firstly, when you need this very "stock" - the paste bought ahead of time may already dry out from improper storage. Secondly, it is not at all a fact that by that time you will not have changed the hardware for a new one, which, due to its novelty, simply does not need maintenance.

The opposite situation: if you have a home electronics repair service, or you service devices that are very different from laptops and PCs in size and the number of heating elements, it is better to buy large volumes at once. An extra trip to the store in the midst of repairs can bring down all the deadlines, and even if the thermal interface runs out in the midst of preventive maintenance at a remote facility, where there are basically no stores, the consequences will be much more vivid and impressive.

Minimum and maximum operating temperature

Owners of ordinary "home" hardware, of course, should not worry about these parameters. An ordinary home PC or laptop with a probability of 99% will not see subzero temperatures, and prolonged heating above 100 degrees usually means that you will not have to go to the store for a new thermal paste.

But fans of extreme overclocking should pay attention to minimum temperature, in which the thermal interface retains its properties. At temperatures below zero, most thermal pastes freeze through and stop performing their tasks, which threatens, at least, with the loss of the planned record. So the passport -80 or -100 - for refrigeration systems based on freon, and - 200 degrees - for liquid nitrogen are simply required.

However, it is worth paying attention to the minimum operating temperature of the thermal interface for engineers who service various electronics operating "in the fresh air." We still live in a northern country, and -40 in winter is not uncommon even for the middle zone, let alone for the Arctic. Of course, you can save on the thermal interface, but after all, someone will then have to do unscheduled preventive repairs in not the best weather conditions ...

Maximum working temperature- a parameter that is important in the event that the paste is applied to an element that has nothing to do with a PC and similar electronics. For example, the temperature of a powerful LED, cooled by a radiator, can easily go beyond 150 degrees, and for a well-loaded transistor, even 200 degrees. And it's not bad at all to have thermal paste, which in such conditions will not dry out and turn into stone during the entire passport service life.

Criteria and choices

Thermal interfaces offered in the stores of the DNS / Technopoint network can be sorted as follows:

Liquid metals and pastes with a high metal content are suitable for extreme overclocking enthusiasts struggling for every degree and megahertz. These interfaces must be used with great care, but when used correctly, they give excellent results.

Thermal pads (except for metal options! ) are necessary for cooling such PC elements as power circuits of video cards and motherboards, memory chips (both on video cards and on modules random access memory equipped with radiators) and hard drives... In addition, they will find their application wherever it is required to cool elements of complex shape and relief, but not too high cooling efficiency is required.

Hot glue useful if you intend to install a heatsink on an element for which there is no common heatsink, and there are no mounting holes on the board that allow screw fastening. The strength of the hot melt adhesive is sufficient to hold the heatsink (or vice versa - the cooled element on the heatsink) without additional fixation.

The range of thermal pastes in BPS includes heat-conducting compounds different types and types: from budget thermal greases, not having great efficiency, but supplied in large volumes, up to top lineups that exhibit ultra-high efficiency and are capable of operating in low temperatures. There are, of course, and "universal" options, at the same time affordable and showing, if not record-breaking, but very good results.

With the onset of heat, the computer becomes louder and the struggle for degrees begins. How to reduce computer noise with your own hands? How to make good thermal pads yourself? In this article, the author has given tests of homemade thermal pads and standard ones that were installed from the very beginning. The result is worthy of attention.

Introduction

- an integral part of any video card with a standard turbine type CO. It is installed between the contact areas of the intensely heated area (video memory, GPU) and the heatsink for better heat dissipation.

In this article I will tell you how you can at home make and install thermal pad not inferior in performance to factory ones.

For robots we need:

Ruler
Thermal paste (It is desirable that there was a 2nd. Viscous and thinner)
Medical bandage (preferably with a small mesh size)
Napkins
Scissors
Screwdrivers (One for unscrewing, the other for stacking and tamping thermal paste)
Clean and spacious desktop 🙂 With the latter, homemade problems
Pliers
Metal scissors
Plate of copper, aluminum (The thickness is selected in each case individually. In my case, I used the thicknesses: copper - 0.8 mm, aluminum - 1mm)
Any material for polishing surfaces

A patient

For experiment, I used MSI NX8800GTS-T2D320E-HD-OC.

There are 23 thermal pads installed in the CRM of this card. The memory chips use 10 thermal pads, and we will change them.

Manufacturing and replacement of thermal pads

Owners of turbine-type cards, when smearing thermal paste on the GPU, often face the problem of the thermal pads falling off or breaking apart. This can be caused by a poor-quality thermal pad, user curvature, or simply the thermal pad is becoming obsolete.

The thermal pad installed in this card is a medium viscosity thermal paste secured with two thin bandages at the top and bottom of the plate. We will be doing something like a factory thermal pad.

First you need to remove the factory thermal pads. After that, wipe it well and remove the remnants of thermal pads (if any) from the memory and from the CO radiator.

Then you need to measure the area of contact between memory and CO. Then, according to your measurements, cut a suitable piece from the bandage. You need to cut it with a margin of 5mm both in height and in width, since when the bandage is lubricated with thermal paste, the bandage will tighten a little.

We will lubricate the cut off bandages with thermal paste. For this I used KPT-8 thermal paste. You need to do this very gently, you need to apply force in moderation so as not to break the bandage.

This is what a potential thermal pad looks like:

Thermal paste should not be overdone, try to smear in moderation. Why can't you just put thermal paste between memory and CO? Because when heated, the thermal paste can flow or spread, which is not good, and the bandage gives the thermal paste a certain strength and viscosity, albeit at a slight damage to heat transfer, however, this is not as critical for memory as for a GPU / CPU. Although, as the tests will show further, the new thermal pads will win ~ 5 degrees over the factory ones.

Before applying oiled bandages, lubricate the memory sections and the memory itself. thin layer thermal paste, this will slightly improve the "friendship" of the contact area with the bandage. Here it is advisable to use not viscous, but liquid thermal paste. It will serve as glue between the bandage and the contact area.

When the thermal pad is in place, cut off the excess bandages with scissors. Then tamp them well with a thin screwdriver.

We cling the CO into place, and we can say that we are done!

Many of you will say that homemade thermal pads lose to factory thermal pads. I have tested with a thermocouple.

Testing

The temperature in the room where the testing was carried out was at the level of 24-25 degrees. Card without mods and overclocking. The frequencies of the card are 576/1350/1674 for GPU / shader domain / memory, respectively. The CO turbine was spun up by 100%, which is ~ 2900 rpm.

The temperature in the rest mode was taken 10 minutes after the intensive load of the card. GPU Caps Viewer in both cases. Temperature recorded: Riva Tuner V2.24. In idle mode, the GPU temperature was 54 degrees, in load mode, the GPU temperature was 75 degrees.

Here's a test bench:

Intel Core 2 Duo E6750 3.5Ghz (444 * 8, Vcore 1.36)
ASUS P5B Deluxe rev 1.2 (BIOS 1215)
Thermalright Ultra 120 eXtreme + Noctua 2 * NF-P12
Thermaltake Extrime Spirit 2
2Gb Corsair XMS2 6400C4 888Mhz (4-4-4-12) V2.2
MSI GeForce 8800 GTS 320MB
Gainward 9500GT PhysX
Seagate 250GB SATA, WD 500GB SATA 2
Case: Raidmax Smilodon

Photo of the test bench:

I put a straw of thermocouple between the memory itself and the thermal pad, this is how I get the approximate data.

Temperature regimes

As you can see from the graphs, the advantage is on the side of homemade thermal pads.

Homemade thermal pads not only are in no way inferior to the thermal pads that come with the video card's CO, but also gain a few degrees. The replacement process is not difficult. All you need to do this is straight overclocking hands, a bit of ingenuity and, of course, time.

Aluminum and copper

In my case, I did not use metal scissors since I do not have them. When buying copper and aluminum, I cut the layers I needed.

We measure the area of the contact area of memory and CO. After that, we cut out suitable plates from the metal.

The plates should be as flat and clean as possible to better heat conductivity.

We glue a polished and even plate onto the memory chips, having previously greased the chips with thermal grease.

I cut copper and aluminum into one plate, and not separately into pieces for each chip, because I had some difficulties in mounting the CO, but this will not negatively affect the efficiency. When slicing copper / aluminum plates, it is important to cover the entire area of the memory chip without leaving any empty area. It is also worth lubricating the sections of contact with the plates with thermal grease on the CO.
We hook the CO into place, and we can say that we are done!

Testing

I didn’t put it between the plate and the heatsink because the GPU temperature was 75 and I would measure the heatsink temperature.
