How often should the notebook be replaced with heat dissipation silicone

First of all, the commonly used heat dissipation silicone grease.

It is non-volatile.

Yes, as long as the quality of the silicone grease is okay and the application is scientific, there is basically no need to consider changing the silicone grease. If you are using silicone grease that has poor thermal conductivity or is easy to dry, it can basically be replaced once a year. The circumstances that need to be replaced may be:

1. Under normal conditions at room temperature, the fan speed peaks and the CPU temperature is too high; 2. When the CPU or heat dissipation module has been replaced; 3. Disassemble the heat dissipation module by yourself and find that the silicone grease is obviously solid. To put it simply, as long as the silicone grease is not dry, there is no need to replace it, which needs to look at the quality of the silicone grease used to judge how long it will take to replace, and it is recommended to disassemble the machine in the official after-sales service, so as not to affect the normal warranty of the whole machine.

1. Common sense: The heat dissipation material commonly used in general CPUs becomes silicone grease, and there is a difference between silicone and silicone grease; The heat dissipation grease is generally changed when cleaning the dust, because it is not possible to disassemble the machine frequently.

2. Replacement frequency: depending on the situation, according to the heat dissipation of the computer, the use of the environment is dusty, and it may take half a year to clean the dust and replace the silicone grease, but in general, it is enough to replace it once a year.

Good heat dissipation grease does not need to be replaced, and good heat dissipation grease will not dry. Poor heat dissipation grease is recommended to be replaced once every 1-2 years.

Changing the silicone grease is when cleaning the ash, if you simply use a small brush to clean the ash, the silicone grease does not need to be changed without damage. If the ash is completely cleaned, the heat sink needs to be replaced with silicone grease, and the replacement of silicone grease is related to the cleaning of hardware such as your CPU (generally 1-2 years of ash cleaning, desktops are generally once a year, if the CPU temperature is not high, do not need to clean the ash). Knights generally don't have to worry too much about changing silicone grease now.

According to your own computer it! I haven't changed it in four years, so there's no need to change it if it's not bad.

Change it every year or so.

If you don't use it often, it can take a longer time. The main function of the silicone grease of the laptop is to cooperate with the CPU and heat pipes to complete the heat dissipation function.

Because long-term heat dissipation will gradually dry out the silicone grease, and the heat dissipation effect will gradually decrease, it still needs to be replaced, and the specific time can be based on your usage habits.

Operating temperature of thermal grease:

Generally, it is not more than 200, the high temperature can reach 300 shots, and the low temperature is generally about -60.

Thermal grease is a highly thermally conductive insulating silicone material that almost never cures and can remain in the same condition as a grease for a long time at temperatures ranging from -50 to +230. It has excellent electrical insulation and excellent thermal conductivity.
