#How long is the lifespan of the silicone grease inside the CPU?
As long as the CPU silicone grease does not dry out, there is no need to replace it. Generally, the drying time is about 1 to 5 years depending on the quality, so please judge how long it takes to replace it depending on the quality of the silicone grease used. .
1. The worst ones cost a few yuan for a small jar. This kind of silicone grease has poor thermal conductivity and dries easily. It is best to replace it within a year.
2. The better thing is that some radiators come with it, which can be replaced every 1-2 years.
3. The better ones are around 20-50 yuan. The quality of this silicone grease can be said to be excellent. It may not be dry in about 3-5 years, and it can still be compared. Good thermal conductivity.
4. The best one is liquid metal, which costs about 50-100 yuan per use. Liquid metal can be used for a long time and does not need to be replaced.
Extended information
Thermal conductive silicone grease, commonly known as heat dissipation paste, uses organic silicone as the main raw material, and adds heat-resistant and excellent thermal conductivity. Material, made of thermally conductive silicone grease compound. It is used for heat conduction and heat dissipation of electronic components such as power amplifiers, transistors, electron tubes, and CPUs, thereby ensuring the stability of the electrical performance of electronic instruments and meters.
Thermal conductive silicone grease is a kind of material used to fill the gap between the CPU and the heat sink. This material is also called thermal interface material. Its function is to conduct the heat emitted by the CPU to the heat sink to keep the CPU temperature at a stable level, prevent the CPU from being damaged due to poor heat dissipation, and extend the service life.
In heat dissipation and thermal conduction applications, even two planes with very smooth surfaces will have gaps when they contact each other. The air in these gaps is a poor conductor of heat and will hinder the conduction of heat to the heat sink. . Thermal conductive silicone grease is a material that can fill these gaps and make heat conduction smoother and faster.
