  • Go to its Settings and then go to its Advanced Settings and find the Monitor section.
  • Change the CPU Fan Speed to ignore and confirm changes.
  • Boot into Windows now and this should get rid of the error messages.

Method #3: Check your hardware

  • Check that your fans are properly connected or not.
  • Also, check whether your motherboard is properly connected to the fans or not.
  • If you see dust around the fans then remove it. You can use compressed air cans for this procedure.
  • Spin the fans manually and see if they are spinning normally or not.
  • Reapply thermal paste to avoid overheating issues.

You may take professional help for this method because it might not be possible for you to check for hardware defects if there are any.

Method #4: Troubleshooting hardware problems

If you feel that there are hardware problems in your PC that are causing the CPU Fan Error then make sure to diagnose which part of the PC is giving you issues.

  • Turn off your computer and unscrew the computer and go to the section where the fans are attached to the motherboard.

Note: These steps should be done only if you have experience doing the same. You should take professional help if this is not an area of expertise for you.

  • Make sure all the cables to the fan are connected and that there are no loose connections. Try replacing the cables as well.
  • Watch the fans spinning when you turn on the PC and see if the spinning movement is normal or not.
  • If the fan is spinning even after you have connected a new cable, it means that your fan is damaged and needs to be replaced.

If everything is correct with your fans then it might be due to a software issue which we will troubleshoot down below.
