1. Silicone grease has poor thermal conductivity and is prone to drying, so it is best to replace it within a year.

2. Some radiators come with it, and this one can be replaced once or twice.

3. Even better, around 20-50 yuan. The quality of this silicone grease can be called excellent, it may not dry out for about 3-5 years, and it can also ensure better thermal conductivity.

4. The best option is liquid metal, which costs around 50-100 yuan per use. Liquid metal can be used for a long time without the need for replacement.

The above is a detailed explanation of how often CPU silicone grease should be replaced, hoping to help everyone.

Strictly speaking, thermal conductive silicone grease is just one type of silicone grease, in addition to insulating silicone grease, lubricating silicone grease, optical transparent silicone grease, etc. Silicone grease is known as the MSG in industry and has a wide range of applications in electrical insulation, lubrication, demolding, rust prevention, corrosion prevention, waterproofing and shock resistance.
