Thermal conductive silicone grease, also known as heat dissipation paste, is a paste made by special silicone oil as base oil, new metal oxide as filler, with a variety of functional additives, and processed by a specific process. Colors vary in appearance from material to material.

        Thermal conductive silicone grease has good thermal conductivity, temperature resistance and insulation properties. It is an ideal medium material for heat-resistant devices, and has stable performance. It will not produce corrosive gases in use and will not affect the metal contacted. On the computer, it is usually applied on CPU and graphics card for auxiliary heat dissipation.

        Thermal conductive silicone grease can be bought online, pay attention to the need to buy CPU with thermal conductive silicone grease, not cured, do not buy a cured, that adhesion will not erase, smear a thin layer of it.

        Thermal conductive silicone grease is packed in toothpaste tube. It looks similar to toothpaste. The main difference is that fillers filled with thermal conductive silicone grease are different. The thermal conductivity of fillers filled with thermal conductive silicone grease can be 1.5-3.0; ordinary toothpaste filled with aluminium hydroxide, thermal conductivity is 0.2-0.3, so it can not be used for heat dissipation.

        Accurately speaking, the computer CPU is coated with silicone grease rather than silica gel, which is used to assist the CPU to heat, so it is not recommended to use other substances instead.

        CPU silicone grease is generally changed once a year, some poor silicone grease life is short, only a few months, so more frequent replacement, the best choice is high-end silicone grease, not only thermal conductivity, but also long life.
