How to apply cpu thermal grease, and what should be paid attention to when applying it


CPU thermal grease is a silicone grease-like material that can conduct heat quickly and dissipate, and this material will not cure after being applied or coated, which can ensure the power tubes, electric heating stacks and thyristors in electrical equipment. The contact surface between the heat dissipation facilities is mainly to play the role of heat dissipation, and can also achieve the characteristics of moisture-proof, corrosion-proof, and dust-proof, which can well protect the normal operation of the cup.


Steps to apply thermal grease

1. First, make sure that the cup or other contact surfaces are clean and free from dust and water.

2. Next, evenly coat the thermal grease on the CPU, which needs to be scraped off with a blade or a brush.

3. In the case of ensuring that the gap is filled, it is necessary to evenly coat the thermal conductive silicone grease, and the height should not exceed 3mm.


Precautions for smearing

1. Pay attention when applying thermal grease. Do not apply too much. Too much will affect heat dissipation. You only need to apply a thin layer. And when smearing, there should be no air bubbles or impurities, and it must be applied evenly, otherwise it will affect the heat dissipation performance of the CPU.

2. Before applying heat dissipation silicone grease, you need to know the conductivity of the brand heat dissipation silicone grease and whether it will corrode metal. If there is metal corrosion, it is not a good heat dissipation silicone grease.

3. Good thermal conductive silicone grease can achieve insulation and temperature resistance after being applied, especially it has no corrosion to metal. At present, the products of big brands can achieve this effect, such as TENSAN, which focuses on the research of thermal silicone grease and provides customized The heat dissipation silicone grease application solution has a wide range of uses and can be used in new energy, military industry, medical treatment, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.


It should be noted that when choosing thermal conductive silicone grease, it is best to choose the tube type, because the tube type is easy to operate and easy to construct, and it is easy to grasp the measurement when extruding during construction. Wipe it clean with a paper towel, otherwise it will contaminate the cup socket or the motherboard.
