The main function of thermal conductive silicone grease is to fill the gap between the contact surface between the CPU chip and the heat sink to conduct heat conduction work; before applying the silicone grease, use high-purity isoamyl alcohol or acetone and a lint-free cloth to contact the chip and the heat sink. Wipe clean, remove the original silicone grease, squeeze an appropriate amount of silicone grease in the center area of the chip, and use a plastic scraper or bank card or bus card to evenly apply the silicone grease to the entire chip. Under the premise of filling the gap, the thinner the better, the more coating is not beneficial, but it will affect the heat transfer efficiency; finally, press the heat sink lightly to the CPU to fix it to complete the operation.
