I'm here to explain in detail how to clean it up.
Tools, brushes. Blowing equipment, such as air pump (no oil leakage) and computer-specific hair dryer. If you have an air compressor, use it.
Brush 1 times where you see it, and then clean it with a blower.
In the process of cleaning, if it is found that the cooling fan does not rotate smoothly, it is recommended to refuel.
If you don't want to bother, move to any computer company to clean up, and the cleaning cost is the highest in 20 yuan! I hope it helps you.
