How Often Do You Change Silicone Grease

How often should the notebook computer's CPU cooling silicone grease be changed? I believe this is a topic that many friends who like to install DIY are more concerned about, because once the CPU temperature is too high, it will affect the performance of the computer to some extent, and if it is serious, it will reduce the life of the computer. Sheen divides the following according to the thermal grease applied to the computer CPU in the computer industry:

Ordinary silicone grease: After disassembling, it can be found that the silicone grease has dried out, and its thermal conductivity is relatively ordinary. Generally, it can only reduce the CPU 3-4 ℃, the average price is 1-2 yuan / gram; within one year, the CPU needs to be re- Apply once

Industrial-grade silicone grease: This kind of silicone grease is commonly used in electronic equipment. It is a thermal grease manufacturer that has reached a cooperation with electronic equipment manufacturers. The average price per gram is within 5-10 yuan. The temperature of the CPU can be reduced by 6-8 ° C. Replace Time is 2 ~ 3 years;

Imported metal silicone grease: According to Xiaobian's understanding, there are usually many foreign brands, and its thermal conductivity is also very good. It can reduce the temperature of the CPU by about 10 ~ 12 ℃, but the price is generally hundreds of yuan per gram. The replacement time is generally about 3-5 years.

PS: When the temperature of the CPU is low, the effect of different silicone greases on the cooling of the CPU cannot be accurately measured. In contrast, the higher the temperature of the computer CPU, the more it can see the thermal conductivity of a thermal grease.
