To learn how to apply thermal grease, you need only two things: a little free time and an Internet connection. There are many articles on this topic on the global Web. They are written by everyone who is not lazy - from venerable computer gurus to beginners who want to assert themselves in this way.
Moreover, the question of how to apply thermal grease is nothing complicated. Even with insufficient accuracy, nothing terrible will happen. Except that the temperatures will be higher than they could be. Although, of course, if you spread such a paste on the motherboard as butter on the bread, then nothing good will come of it. Speaking of sloppiness, we mean reasonable limits., , , . , . , . , . , , .

It follows that to increase the efficiency of heat dissipation, it is necessary to eliminate all defects in surface treatment: they should be perfectly even, parallel, and the vector of the pressing force would be an exact perpendicular. However, instead of performing such meticulous work in production, a different solution is used. A viscous mass is applied between the surfaces, which compensates for processing defects due to fluidity. In fact, we are talking about an intermediate thermal interface with a high coefficient of thermal conductivity. The best thermal grease should have the following properties:- transfer heat no worse than the material of the radiator;
- be liquid, but not spread out;
- have the ability to "stick" to surfaces.
It is easy to understand that thermal paste manufacturers compromise by trying to combine the opposite properties in the product. Very often, the composition of the pastes is kept secret, so it is difficult to verify the statements of manufacturers. For example, Zalman thermal paste, in which zinc oxide is the base , dissipates 1.2 W / m * K, while the Soviet KPT-8 is only 0.7 units. However, knowing how to apply thermal grease correctly, it is possible to achieve quite acceptable heat sink efficiency.. . . , (-, , ). . , .
