Most computer gamers know that before installing the CPU cooler, you need to apply a thin layer of thermal grease evenly between the CPU and the radiator base, so as to obtain better thermal conductivity. Moreover, when the computer has been used for a long time, it is necessary to check whether the silicone grease is dry when cleaning the dust. Generally, it needs to be reapplied to improve the cooling capacity of the CPU.

Are there any other things besides silicone grease for cooling accessories? Today we are going to give a popular science to novice players. Reprinted from Computer Pepsi.com Reprinted from Computer Pepsi Network Reprinted from Computer Pepsi Network Silicone grease is used to fill the gap and reduce the thermal resistance between the processor and the heat sink. Reprinted from Computer Pepsi Network Reprinted from Computer Pepsi Network The grease only needs to be evenly applied in a thin layer. Too much or too little will affect the heat dissipation effect. For details, see: How to apply silicone grease to the CPU to dissipate heat best? Comparison of CPU smearing methods of silicone grease reprinted from the computer Pepsi network. We know that the top cover of the processor and the bottom of the radiator are made of metal (usually copper or aluminum alloy), and no matter how perfect the manufacturing process is, it cannot guarantee their performance. The surface is absolutely flat and smooth, which will leave a tiny gap when the two are in direct contact. In addition, if the player is not installing the radiator flat when installing the radiator, it will also cause the bottom of the radiator to be warped and a gap will appear (very Small gaps may not have much effect, if the radiator base is too crooked, it will have to be reinstalled). It is because of these gaps that there is a small amount of air between the processor and the heat sink base, and the air can seriously affect the thermal conductivity. Therefore, we need to fill these gaps with a filler, and silicone grease is the best choice for cost performance and applicability. However, don't think that the more silicone grease is applied, the better. In fact, the thermal conductivity of silicone grease (W/m·K, also known as thermal conductivity) is between 0.8 and 8, which is similar to the thermal conductivity of copper 377. The gap is very different, so it can only be used to fill the gap, and too much coating is a burden for heat dissipation.
