CPU thermal conductivity Silicone grease using method

As the heart of the computer, the calorific value of the CPU is quite alarming. General CPU through thermal conductivity silicone grease will heat into the radiator, so as to achieve the purpose of cooling. CPU heat is too high, the system will occur blue screen, panic, restart and so on, so the thermal conductivity of the CPU becomes particularly important. So how do we go about using thermal grease?

It is best to apply thermal grease between the heatsink and the CPU when installing the cooling fan. The role of silicone grease is not only the heat produced by the CPU quickly and evenly passed to the heat sink, in many cases, silicone grease can also increase the heat sink not too flat under the surface of the heat contact with the CPU.

and silicone grease has a certain viscosity, in the fixed heat sink metal shrapnel slightly aging loose, you can to a certain extent so that the heatsink will not be separated from the CPU surface to maintain the performance of the cooling fan.

Effect of thickness of silicone grease on heat dissipation

Theoretically speaking, in the guarantee can fill the CPU/GPU and radiator surface gap, the thermal conductivity of silicone grease layer is thinner the better, after all, in terms of thermal conductivity, the better silicone grease than copper and aluminum metal materials. In front of the thermal conductivity of this parameter said, the copper thermal conductivity is high-grade thermal conductivity of silicone grease about a hundredfold.

How should heat conduction silicone grease apply?

Thermal grease should be how to smear, there is no very standard argument, but there is a rule, the key is to apply evenly, no bubbles, no impurities, as thin as possible.

Now there are two main ways to apply, one is in the CPU/GPU and other surface center squeeze a bit of silicone grease, and then rely on the radiator pressure to squeeze the silicone grease evenly, the other way is to evenly apply the silicone grease on the CPU/GPU surface. Obviously the first method is suitable for a small surface area heat source, the second method is more suitable for the larger surface area of the CPU/GPU, such as the Intel Core 2 series processor, but the second method is easy to get impurities, also may produce bubbles, a lot of thermal grease products are shipped with a scraper or plastic sleeve to facilitate smear
