What is the easiest way to clean the dust of my PC's CPU fan?

remove it, wash it, dry it, then reinstall it. don’t forget to clean the heat conducting paste from it and the cpu and apply new paste when you reinstall it.

DRY IT

that is for the cooler, not the fan, for that, remove it and clean it with a cloth.

Dust will definitely cause problems in your computer and it should be cleaned our regularly.

#1. Always unplug the power cable before opening your computer. Make sure that you touch something metal on your case before anything else so if you have any static electricity, you discharge it safely on the case metal instead of on your expensive electronics.

Get some compressed air and blow out the dust. Be careful not to inhale the dust because it’s not good for you at all.

If you want to clean your fan particularly, you can use a q tip with a little alcohol.

Pulling the cpu fan off your processor and cleaning it manually would be a good option if you are comfortable with that process. If you’ve never done that before, I might not recommend that first.

Remove fan , attack it with a cotton swab and blow , then insert fan and yay clean fan . Also attach a hoover to the area and suck everything out .

But how do I remove the fan?

@archaeopteryx Get a can of compressed air. That will help a lot.

When you open your pc you will see .

Power supply fans : You need to open using screw driver
Mother board : Two clips either side of the fan
Extra fan : 3 pin connector .
You could just hoover the dust when you have blasted it with the swab ( Q -tip)

I use compressed air as well. It makes a huge mess, which I then vacuum up.
