How to disassemble the host and clean the CPU fan? You'd better make way.

Quite simply, cleaning the cpu fan requires a Phillips screwdriver, a soft brush, toilet paper and pure alcohol. It is recommended not to remove it for cleaning, because it needs to be daubed with thermal conductive paste, that is, silicone grease. If it must be removed, prepare a small bag of hot compress. The steps are as follows: open the main cover → remove the fan with a universal Phillips screwdriver (remember to twist four screws diagonally when removing) → clean the dust with a soft brush, and wipe it with alcohol if it is difficult to clean. Then wipe the dust at the cpu of the motherboard with soft toilet paper. Remember to wipe off the white thermal paste → finally, apply a little thermal paste you bought on the cpu, not too much, just the size of your little finger nail, and then install a fan, which is also twisted obliquely. Finally, just cover the host, and the whole process can't be powered on! (pure hands! )
