How to Disable a CPU Fan Error


Most computers have a fan to cool the central processing unit and prevent it from overheating. If this fan stops working, the computer can display an error to inform you of the problem. This warning will also sometimes appear if you are using a nonstandard CPU fan. The system detects this fan as abnormal or fails to detect it at all. If this happens, you can turn off the error warning from within the BIOS menu.

  • Start or restart your computer.

  • Load the BIOS menu by holding down the appropriate key as your computer starts up. Refer to the machine's manual to find the specific key. It is normally "Delete," "Esc" or one of the function keys, such as "F1."

  • Navigate around the BIOS menu using the arrow keys and select options using the "Enter" key. You can use the "Esc" key to return to the previous screen at any point.

  • Locate the "CPU Fan Warning" option. This will normally be under "PC Health Status," but the exact location may vary depending on your machine.

  • Switch this option to "Disabled" by selecting it and then changing it using the arrow keys.

  • Press "F10" to save the settings and exit the BIOS menu. Your computer will continue loading and you should no longer see the CPU fan error.
