Why are my case fans not working?

Causes of a case fan not spinning may include dust or debris accumulation, physical damage to the fan, incorrect connections or software issues, and a malfunctioning power supply.

There can be several reasons why the case fans won't turn on. Here are a few things you can try to troubleshoot the issue:

1. Check the connections: Make sure that the case fans are properly connected to the motherboard, and that the power cables are securely connected to the PSU.

2. Dust and debris: Dust and debris can accumulate on the fan blades and prevent them from spinning. Try cleaning the fans with compressed air or a soft brush.

3. Fan controller: Some cases come with built- in fan controllers, which can be used to adjust the fan speed. If your case has a fan controller, make sure it is properly configured.

4 Test the fans: If you have any spare fans or can borrow from other systems, you can test if the issue is with the fans or something else.

5. BIOS settings: Check the BIOS settings to see if the fan control is enabled or disabled.

If none of these steps help, it is possible that the fans or the motherboard might be faulty. In this case, you may need to get professional help to diagnose and fix the issue.

If the case fans are not turning on and there are no lights or fan movement, there are a few things you can check:
  1. Power supply: Make sure that the power supply is turned on and providing power to the computer. Check that the power cable is securely plugged into the wall outlet and the power supply unit (PSU) at the back of the computer.
  2. Fan connections: Check that the case fans are properly connected to the motherboard or fan controller. Make sure that the fan cables are securely plugged into the correct fan headers on the motherboard or fan controller. You can also try disconnecting and reconnecting the fan cables to ensure a good connection.
  3. Fan settings: Check the BIOS settings to make sure that the fans are set to "Auto" or "Enabled". If the fans are set to "Disabled" or "Manual", they will not turn on. You can also try changing the fan settings to "Full Speed" to see if that helps.
  4. Fan controller: If your computer has a fan controller, make sure that it is properly connected and configured. Check the manual for the fan controller to ensure that it is set up correctly.
  5. Faulty fans: If none of the above solutions work, it's possible that the fans themselves are faulty. Try testing the fans on another system to see if they work. If they don't work, you may need to replace the fans.

If you're still having trouble, it may be helpful to consult with a computer technician who can diagnose the issue more accurately
