How to Repair the CPU Fan Error Technically in BIOS

Understand the Meaning of CPU Fan Error; You may have experienced the CPU (Central Processing Unit) fan error notification on your computer. It is a general error that arrives when you turn on your system. It is an alert message that appears when the PC or laptop shuts down automatically due to excessive heating. Also, it occurs when the CPU fan cannot cool off other PC components.

It is troublesome when the PC shuts down immediately due to improper functioning of the CPU fan. However, the forced closing down of PC indicates it is safe and secure. Still, failure of CPU fans leads to extreme heating of computer that can cause lasting wear and tear of computer parts.

Various Causes of CPU Fan Glitch

There are many causes for CPU fan error alerts. The general thing that can cause CPU fan failure is dirt particles. Filth gets collected in the PC or laptop that avert the heatsink metal to function suitably. Consequently, it gets problematic for the system to air-cool resulting in the CPU fan glitch.

Besides, a damaged or inaccurately attached CPU fan is a further reason for CPU fan error notifications. Luckily, you have the option to repair the CPU fan error without the support of a PC repair person.

How does the CPU Fan Error Flashes?

Usually, the CPU fan error flashes when you initiate or boot the computer. This alert does not emerge when the Windows PC function normally. You may notice the CPU fan error notifications in the ways given below:

  • CPU Fan Error (Generic)
  • Error: CPU Fan Has Failed (ASUS)
  • CPU fan speed error detected. (American Megatrends)
  • CPU fan error, Please check! (MSI)
  • System Fan (90B) (Compaq/HP)

Methods to Repair the CPU Fan Error Using BIOS Utility

  1. At first, trigger BIOS utility.
  2. Next, pick the Monitor option.
  3. Under Monitor, choose the Fan Speed Monitor option.
  4. Press N/A —> Ignore —> Exit.
  5. Finally, press on the Save option to confirm BIOS modifications.

Note: Make changes in the BIOS setup only if you are assured that the CPU fan is functioning accurately. Otherwise, bear in mind that applying these modifications may impact your system’s power to notice CPU fan failures and unnecessary heating of components.

Final Thoughts on Repair the CPU Fan Error

We expect that the implication, causes, message arrival, and methods of fixing the CPU fan failure technically via BIOS are coherent to you. Therefore, use the preceding techniques to settle CPU fan error notification. If the above tricks do not work, try cleaning or replacing the CPU fan.
