CPU Cooling Fan Installation

The CPU cooling fan does a vital job in your computer. It draws the heat away and stops the possibility of the unit overheating, allowing it to run properly. Without it the computer would quickly become too hot and shut down. A CPU cooling fan needs to be cleaned, and periodically it needs to be replaced. It’s a simple job, one that even people who don’t work on computers can do.

Step 1 - When to Replace

The first question is when to renew the CPU cooling fan. If the fan starts to become noisy then you know you need to replace it. Similarly, if your computer keeps shutting down then working again for a short while when cool again, the CPU cooling fan is at fault. Don’t keep using the computer if this happens. There’s a grave risk of seriously damaging the machine and possibly losing all the data you have on it (always back up all your data).

Step 2 - Type of Fan

There’s no single CPU cooling fan that will fit all computers. You need to know the make and model of your desktop computer first. Selecting the right fan for your unit is important. A fan that’s too small will struggle and burn out quickly. One that’s too big will use too much power. Research the right fan online and buy it at the best price. A new fan is cheap and works hard.

Step 3 - Remove Old Fan

Turn off the computer. Remove the power cord and the cords for all devices from the tower. Place the computer where it can easily be worked on and unscrew the side panel that gives access to the interior.

The old CPU cooling fan will be located on the processor. It’s a square metal unit; you’ll be able to spot it from the shape of the new fan. It will either be held in place by clips or screws. If the CPU cooling fan is held in place by screw, unscrew them gently and keep the screws safe. Lift off the fan. If held in by clips, open them and remove the fan. There could also be a combination of screws and clips; it depends on the make and model of computer.

Step 4 - Installation

Some computers use a thermal paste or thermal pad where the fan joins the processor. If so, put in place before installing the CPU cooling fan. Spread the paste very lightly. Put the new fan in place and tighten down.

Remove the fan again to make sure that the thermal paste has spread enough so that all parts of the fan that touch the processor are in contact with the paste. Install the fan again and tighten down. Put the side panel back in place and screw down. Re-attach all the cords and boot up the computer to make sure that the new CPU cooling fan works correctly. It should be virtually silent.
