If all else fails try these simple fixes to fix your CPU fan. Hopefully one of them will work for you! If not read on to learn how to solve this problem!
Fixing a cpu fan that won’t spin
If you’ve ever had problems with a CPU fan it’s likely the fan itself isn’t spinning properly. This happens because CPU fans don’t produce a lot of torque and they can get blocked by the wiring that runs through the motor. To fix this problem you can cut the wiring and secure it with epoxy. If the problem persists you should check the rest of the cooling system.
First make sure that the CPU fan is supplying enough power to run. You can test this by removing it from the computer and comparing it to a known-working fan. To make sure that the fan is functioning properly you need to check its terminals to see if there are any wires coiled up inside. If the fan is still not spinning you may need to replace the motherboard or CPU.
Checking if your PSU is old or bad
To check whether your power supply is old or bad you should open your computer case and check the inside of the power connector. Check the plugs for broken or loose metal connections as well as the insulation of the cable. If you suspect the plugs are bad use a multimeter to measure the voltage. If you see any of these signs you should replace the power supply. Before performing the test keep in mind that working close to high voltage electricity can be dangerous.
The power supply can be a sign of other problems. If it fails to deliver enough power your system will not boot up. In some cases it may be overheating or misaligning the driver slots. If you notice this problem after your PC is completely shut down the first thing to do is to switch off your computer and check the power supply. In case you’re not able to switch off your PC you can unplug the power supply and plug it into a surge protector. You can also try other power cables. If the problem persists listen to the computer for a whirring noise.
Checking if your CPU fan is faulty
If your CPU fan is not working properly then your computer is probably overheating. If you don’t hear any noises while turning on your computer then this is a sure sign that your CPU fan is faulty. A faulty CPU fan should make a sound when your computer is overheating but if the fan doesn’t then your CPU may be faulty. To check if your CPU fan is faulty use a computer inspection tool to check its internals.
First open the BIOS and verify that the CPU fan is properly connected. If it is you should press F10 to open your BIOS settings. You should find a section that focuses on fan control. Usually you can find this under Advanced Settings. Look for Q-Fan control. If this option is not enabled then click OK and exit. If you still get an error message then your CPU fan is damaged.
Getting a new CPU fan
If your CPU fan doesn’t spin you can test its operation by inserting a test device into the case of your PC. Putting some machine oil on the fan’s axis may fix the problem. If that fails you can try to re-set your BIOS. The Esc key and the F9 button will open the BIOS settings. If neither of those works it may be time to replace the motherboard.
Another common reason why your CPU fan isn’t spinning is due to dust buildup. As a result it may slow down the speed of your CPU and cause the fan to malfunction. To avoid this clean the fan on your computer and it should continue to spin normally. Alternatively the CPU bearing could be clogged. This happens to most people every one to two years. CPU fans can also become overworked and stop spinning.
