With the promotion of computer performance, power consumption of CPU is increasing constantly. Due to technology improvement, the power consumption has been alleviated, but because of the enhancement of graphics performance, CPU power consumption is proportional to its performance. Therefore it is still a worthy of our attention that the power consumption is too large to result in higher temperature. Now there has been a very high degree of concern about the heat dissipation problem, however, the majority of consumers simply consider big CPU radiator can solve the dissipation problem. In fact, this idea is very one-side because except for CPU and heat radiator,
thermal grease is also very significant and cannot be ignored in the aspects of solving CPU heat dissipation problems.
For many people, thermal grease may not be very striking thing, but it is a very significant link between CPU and
radiator. If the way of installing and smearing is not correct, it will lead the temperature of CPU to increase and can even result in the device damage. Thus it is very important to smear thermal grease correctly. There are two main ways, as shown in the following figures: one is that a little grease is squeezed in the center of CPU/GPU surface, and then it is extruded evenly by a radiator; the other one is that the thermal grease is smeared on the surface of CPU/GPU by a finger. The first method is suitable for a relatively small surface area and the second one is more suitable for a larger area.
