How to Apply Thermal Conductive Silicone Grease to Computer CPU

The hot summer is coming. Is the computer automatically shut down for no reason? Hurry up and do the "heatstroke prevention" work for the computer. Coat your beloved computer CPU with heat conductive silicone grease (heat dissipation paste) "Thermal Conductive Silicone Grease" may not be a very noticeable object to many friends, but it is a link between CPU and radiator to transfer heat. If the method is not used in the installation and smearing process, the CPU temperature will probably remain high and even burn down. Therefore, the application of silicone grease is very important. Graphic CPU Coated with Thermal Conductive Silicone Grease (Heat Dissipation Paste) Influence of Silicone Grease Coating Thickness on Heat Dissipation Usage of Heat Dissipation Silicone Theoretically, the thinner the thermal conductive silicone grease layer is, the better it is on the premise of ensuring the gap between CPU/GPU and radiator surface. After all, no matter how good the thermal conductivity is, the silicone grease is no better than copper and aluminum. As mentioned earlier when talking about the parameter of thermal conductivity, the thermal conductivity of copper is about 100 times higher than that of high-grade thermal silicone grease. In fact, many people are afraid of not enough silicone grease and apply n more silicone grease. what will be the result? Let's do a simple test, using (Arctic Alumina Silicone Grease) Arctic aluminum, apply appropriate amount at one time, apply more at one time intentionally, and test the CPU temperature of 28 degrees at room temperature under two conditions). Use the temperature and pressure test of Master Lu's software to test. It can make CPU operate under high load and record the temperature change curve. After the test, the silicone grease on the CPU surface (appropriate amount of silicone grease) and the application method of the heat dissipation silicone gel Under the condition of appropriate amount of silicone grease, CPU temperature fluctuates between 61-62℃ Silicon grease on CPU surface after test (more silicon grease) In the case of a large amount of silicone grease, the CPU temperature fluctuates between 63-64℃. It can be found that the thickness of the silicone grease layer still has an obvious effect on heat dissipation. From this test, there is a gap of 2℃ between the two, which is larger than we imagined. There is still no very standard statement on how to apply the heat-conducting silicone grease, but there is a rule that the key to applying is to be uniform, bubble-free, impurity-free and as thin as possible. Use method of heat dissipation silica gel At present, there are two main ways of smearing: one is to squeeze a little silicone grease on the center of CPU/GPU and other surfaces, and then squeeze the silicone grease evenly by the pressure of the radiator; the other is to evenly smear the silicone grease on the CPU/GPU and other surfaces. Obviously, the first method is suitable for heat sources with smaller surface area, and the second method is more suitable for CPU/GPU with larger surface area, such as (Intel Core 2 series processors). However, the second method is easy to smear with impurities and may generate bubbles. Many thermally conductive silicone grease products are supplied with scrapers or rubber sleeves for easy smearing.
