How to fix the CPU fan speed error

Every computer, desktop or laptop has at least one follower. The fan keeps the computer cool and is preset to run automatically when the system heats up. There is a temperature threshold that stimulates the fan when it crosses.

CPU fan speed error

CPU fans turn on automatically when you press a system. The temperature settings do not apply until you tap the desktop. While your system is on the boot device or on the BIOS screen, the fan will continue to keep the system cool. If you go to BIOS or you are on the boot device and you see CPU fan speed error, try the solutions below.

1. Change fan speed from BIOS

Fan speed is not always accessible but in some cases, you can change from BIOS.

  1. Boot the system into BIOS.
  2. Look for the hardware tab or anything related to hardware configuration.
  3. Adjust the speed of the fan or the temperature it excites.
  4. Save the change.

2. Change fan speed on Windows 10

You can try changing the fan speed from Windows 10 if you do not have the option to do so in BIOS.

  1. Download and install an app called HWiNFO.
  2. Run the app.
  3. Click on the fan icon at the bottom.
  4. In the window that opens, click Set manual next to a fan.
  5. Set a temperature to activate the fan.
  6. Set the minimum and maximum speed.
  7. Apply the change.
  8. Restart the system.

3. Check hardware

The fan is hardware and like any other hardware, it can be damaged. If you know your way around a laptop or desk, you can open it and find out if something is wrong eg loose string.

You should also consider looking at a professional. There may be a problem with the temperature sensor. The temperature sensor measures the temperature of a system and makes the fan run. If damaged, the fan can run when it is not needed or may not run when it should.


The fan will not run games, make noise, or process tasks but will keep the system temperature stable, and prevent hardware damage. If you are getting a fan error, you should pay attention to it and make sure it is fixed. Your computer may shut down if it gets too hot but that scan may not work on all systems, and may fail if the temperature sensor is damaged.
