Thermopaste KPT-8: description and characteristics. KPT-8 - heat conducting paste

As you know, computers and laptops with a longvery hot. And the most vulnerable parts are just the processor and video card. In this regard, all manufacturers are trying to provide the most maximum cooling for these two elements. And when assembling the processor, no conscientious manufacturer can do without the use of such a substance as thermal paste.

In general this part is used not only forconveyor for the manufacture of PC components and laptops, but also mandatory for repairing the processor for better thermal conductivity. And today we will talk about what has the thermal paste KPT-8 characteristics and how to correctly apply it.

What it is?

The thermopaste is a multicomponentan element that is in a flexible plastic state. In its properties, it serves as a good thermal conductor, so it is often used to reduce the temperature resistance between the touching surfaces of computer parts. In other words, the thermal paste KPT-8 fills all the irregularities of the radiator and processor, thereby reducing their heating (by several degrees).

It should be noted that this cavity can externallyseem absolutely flat. But this is not so. If you look closely (preferably through specialized tools), you can see a lot of depressions and microcracks. They create a certain air cushion during operation, which prevents the normal removal of heat. As a result, the processor overheats and fails. To prevent this from happening, all existing microcracks are sealed with special thermal paste KPT-8. The removal of heat to the radiator - this is the key task that this substance performs.

Thermopaste KPT-8: reviews and features

Outwardly it is a homogeneous substancewhite color with a thermal conductivity of the order of 0.7-0.95 W / mx K. In this case, its specific electrical resistance level is 1014 Ohm (sometimes this figure may be slightly higher than the specified rate). The operating temperature at which the thermal paste does not lose its properties is from minus 60 to plus 300 degrees Celsius. Thus, KPT-8 (reviews also note this point) provides excellent thermal conductivity under any CPU or graphics card load.

About the cost

It should be noted that this thermal paste canTo be sold both in a tube, and in a small jar. As for the cost, 10-gram jar KPT-8 costs about 55 rubles. For a tube it is necessary to lay out approximately in 2 times more, as its weight makes 18 grammes.

Thermal paste KPT-8 and 20-kilogram buckets are also sold, however, there is simply no point in purchasing them. For the processor it is sufficient to use only a few grams of the substance.

How correctly to put KPT-8 on the surface of the processor? Nuances

Just note that for this you do not need to havespecial skills and expensive tools. The main thing is to remember that the layer of thermal paste must be applied in such a way that the surface of the radiator and the processor fit tightly to each other. In other words, the paste should fill only the cavities and microcracks. All the rest of the space should not be handled by it.

How to start work?

First we need to clean the surfacemicrocircuits from the remains of the old thermal paste. You can do this with a regular soft cloth. Alternatively, you can take a jar of ethyl alcohol and handle the surface of the parts. In the latter case, it is better to use cotton buds.

By the way, these are not the only examples of howYou can clean the surface of the processor from the remains of the old thermal paste. There is another effective method. He is in the use of ordinary clerical rubber bands. With it, it is possible to effectively clean the old layer of paste from the metal surface of the element. However, for this you need to have very strong fingers. Despite the physical complexity of this method, the method with an elastic band is the most safe for the processor itself and the radiator.

Next, we remove the remnants of thermal paste from the soleplateradiator cooler. Everything, now the processor is completely freed from the old paste. But do not rush to put a new one on it. First, you need to rub the "zero" layer of thermal paste into these two surfaces (that is, remove it after the preliminary application). So the substance will remain only in the right places - hollows and microcracks.

Now go to the main stage - the application. Gently squeeze a little of the thermal paste from the tube on the main chip. Many computer programmers recommend applying it diagonally crosswise. In this way, you will achieve the best lubrication of the elements along the entire perimeter of the surfaces. Remember that the layer of thermal paste should be very even and, most importantly, thin (even slightly translucent). Distribute the product on the surface of the metal evenly very simply - just hold the elements with a plastic card. Do not make a centimeter layer between the processor and the radiator, using the principle "the more, the better." All this will only exacerbate the quality of conductivity and heat dissipation from the processor to the radiator. As a result, you simply overheat and burn an expensive item that will no longer be subject to any restoration.

The final stage

After the layer of thermal grease is evenly distributeddistributed over the surface, and the excess will be removed, you can safely fix the radiator over the processor and press it with the locking locks. Everything, on this whole repair is over. As you can see, everything is very simple and not too difficult (except for the trouble with the removal of the old layer of paste). And most importantly - now your computer will be less exposed to various overheats and certainly will not fail because of unnecessary overload.

So, we found out what thethermal paste KPT-8 and how to apply it correctly on the metal surface of the processor and radiator. Remember that overheating of the processor can certainly lead to its failure. Take care of your computer and apply the thermal paste correctly.
