How to clean a cpu fan
Shut down your pc and turn the power off.
Remove the power cords from the rear of the tower and disconnect them from their power source.
Place the tower on top of an anti-static mat that has been laid on top of a table.
OPTIONS:
- Unscrew the screws holding the tower in place. These screws may not work immediately because you may need to cut some threads that may interfere with the screw.
- You may also wear an antistatic wristband that is connected to an electrical ground, like a metal plumbing fixture. You'll need to use the antistatic devices because static discharge from the floor or from your body could damage data stored on the computer.
- Make sure to remove the connections between the wires to make sure they are completely free of any metal tension. Place the tower through the x-bolt hole on one of the battery terminals.
- You will find this mat where you will place the fan into place. Turning off the main power source will help prevent friction, which is likely to occur when testing out your motherboard.

answer: You may also wear an antistatic wristband that is connected to an electrical ground, like a metal plumbing fixture. You'll need to use the antistatic devices because static discharge from the floor or from your body could damage data stored on the computer.
