Dust Removal from Electrical Box Fans
Step one.
Check the dust condition of the dust cover and
fan blades of the electrical box fan.
Timely cleaning the dust of the cooling fan helps to
improve the working environment of the motherboard
and prevent the drive from overheating and
out-of-step phenomenon.
Step two:
Remove the dust cover. Insert and gently pull
out the dust cover from the four corners of the dust
cover
Step three:
Remove dust from the dust cover and fans. Use
an air gun to remove the dust from the sponge in the
dust cover, and blow clean the fan (note that the
pressure should not be too high when blowing the
fan, so as not to damage the fan. You can limit the
rotation of the fan).
