If you’re dealing with a particular issue involving your processor fan, whereas your computer starts normally but the CPU fan does not, we can help you out.

The PC suddenly stopping after it’s been turned on is an outcome to your processor fan not working. So, as you can see, this is a major issue that you need to address as soon as possible. We will present you 4 simple ways of doing so.

Why your CPU fan won’t spin

There are 3 main reasons why your CPU fan is not spinning properly: the fan is clogged with dust, wires might get stuck in the fan or the fan does not get enough energy supply to spin.

Getting rid of these 3 causes might get your CPU fan up and running again.

What to do if your processor fan is not running

  1. Restart your computer
  2. Clean your fan
  3. Repair or replace your power supply unit
  4. Replace your fan and motherboard

1. Restart your computer

As simple as it sounds, restarting your computer might be the fix for your issue. If you already did that, check our next solution.

2. Clean your fan

Cleaning your fan is not an easy task if you haven’t done it before. Try asking for a specialist’s help, as this is a very high precision task. Not knowing how to properly do it could bring irreparable damage to your CPU and computer.

The specialist will also check if you have any wires that are preventing the fan from spinning.

3. Repair or replace your power supply unit

As you might have guessed by now, if your power supply does not work, your fan will not spin. So before replacing your motherboard or CPU, try replacing your power supply first.

This solution usually works if your computer is already making beeping noises or shuts down suddenly.

Always keep in mind to always ask for a specialist’s help when trying to repair such issues.

4. Replace your fan and motherboard

If nothing works, you should definitely consider replacing your fan. If this does not work, the only thing left to do is to replace the motherboard.

If you don’t know what motherboard to buy, check out the options listed in the following guides:

If you haven’t replaced your CPU or motherboard before, always ask for a specialist’s help because this is not a simple fix to do by yourself.

We hope this helps you out.
