How To Mount A Cooling Fan Inside Your Computer

Things You’ll Need:

CPU cooling fan
Anti-ESD (Electrostatic Discharge) wrist strap
Can of compressed air
Phillips screwdriver


1.  First, locate a static free and uncarpeted area to work. Unplug the power cords that are connected to your computer and electrical outlet.

2.  Wear an anti-ESD wrist strap to prevent an electrostatic discharge. Next, use a Phillips screwdriver to remove any screws that are attached to the computer case. If there aren’t any screws holding the cover in place, you may need to search for a latch, then press down on it to open your computer.

3.  Remove the old CPU cooling fan from your computer. Disconnect the fan power supply connector from your motherboard. Unlatch the clamping mechanism for the fan and lift it off of the heatsink. Before you perform the next step, use a can of compressed air to remove any dirt or dust build up from the heatsink.

4.  Mount the new CPU cooling fan. Align the fan over the heatsink and CPU processor on your motherboard. The base of the cooling fan normally has several mounting posts that you will need to line up with the mounting holes on the motherboard. Press down on each post until it snaps or securely locks the fan into place.

5.  Connect the cooling fan power supply cable. Line up the fan’s power supply connector with the motherboard and snap it into place.

6. Test the new cooling fan after you have installed it. Power on your computer to ensure that the fan is working properly.

7.  Close your computer case. Replace the cover and re-tighten any screws that you previously removed from the case.


At least once a month, clean in and around the cooling fan to help keep your computer from developing thermal heating problems. Always use a can of compressed air to remove dirt and dust build up.

If the cooling fan begins to malfunction, and the temperature inside your computer becomes really hot, don’t keep it powered on. Shut down your computer, so that you can determine what is causing the problem. Otherwise, you may permanently damage the components on the motherboard.
