Can the CPU not be coated with thermal grease? Is it important?


Thermal grease has a good effect in heat dissipation. It is used in many electrical appliances and is very popular in the manufacturing industry. In order to cater to market demand, different brands and specifications of thermal grease are divided into different fields of use. There are also universal thermal greases. , this type of thermally conductive silicone grease can be used in a variety of electrical appliances, such as CPUs, LEDs, routers, sensors, etc.

I would like to ask, can the CPU not be coated with thermal grease?

The CPU must not be coated with thermal grease because there are gaps between the CPU and the radiator. These gaps may be visible to the naked eye, but there is a lot of air in these gaps. Air is a non-conductor and the CPU cannot fully contact the radiator. Thermal conductivity will cause the heat energy to be unable to be transmitted.

Although thermal grease is a thermally conductive material, its main function is to fill the gap so that the CPU and the radiator are in full contact. There is no gap between the two, so that the heat energy can be transferred out in time without causing heat accumulation and burning the CPU.

Why does the CPU still burn after applying thermal grease?

The CPU has a good heat dissipation effect after applying thermal grease, but sometimes burnout occurs. The main reason is that the thermal grease contains metallic silver powder. Although this type of thermal grease has good thermal conductivity, it has poor insulation properties. Worse, the overflowing silicone grease can easily contaminate surrounding relays, causing contamination of the relays, causing electrical short circuits and even burns. The current brands of thermal grease not only have good thermal conductivity but also have insulation properties. For example, TENSAN focuses on the research of thermal grease and provides customized thermal grease application solutions. It has a wide range of uses and can be used in new energy, military industry, and medical treatment. , aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

Thermal conductive silicone grease is of great importance in the field of electrical appliance manufacturing. It is an irreplaceable product. As long as electrical appliances need to dissipate heat, thermal conductive silicone grease can be applied. Since it is used in a wide range of areas, the product shelf life has been upgraded during production. The general warranty period For 3 years, there will be no problems as long as it is stored properly.
