Key notes
You can add a variety ofcooling fansto your PC casing, but the CPU fan is essential and irreplaceable.
That’s why it’s hard to ignore the CPU fan error on thebootthat some users keep getting. Thaterrorusually points to a malfunction of the CPU fan or underperforming RPM.
We have a few tips on resolving theerrorwithout too much hustle. Check them out below.
Why does my BIOS say CPU fan error?
An error that occurs at startup caused by the central processing unit (CPU) fan is frequently the result of physical damage to the fan itself, faulty settings, or external circumstances that cause the computer to overheat and force the fan to spin at speeds that are exceptionally high.
Alternatively, errors with the computer’s central processing unit (CPU) fan might be brought on by dirt or other debris that obstructs the device’s air vents.
How do I fix CPU fan speed error?
Before moving on to more complex solutions, make sure to do the following:
1. Update BIOS
It’s more likely to work out CPU fan error on boot by accessing your BIOS and update the firmware of your Windows PC.
-
Download the newest BIOS version from your motherboard manufacturer’s website and copy it onto anUSB flash drive.
-
Open theStart Menuthen click thePowerbutton. Hold theShiftkey and choose theRestartoption.
-
You should see several options available. ChooseTroubleshootfollowed byAdvanced options.
-
SelectUEFI Firmware Settings.
-
Click theRestartbutton and your computer should now boot to BIOS.
-
Once you enter BIOS, look for theBIOS updateoption and select it.
-
Now you need to choose the BIOS update file from yourUSB flash driveand wait while your BIOS updates.

2. Lower the default fan RPM in BIOS
3. Disable CPU Fan speed monitoring in BIOS
After that, the CPU fan pressF1error should be gone. However, if the issue persists, take your PC for diagnostics and repair.
4. Try another CPU fan header
In some cases, your PC might have more than one CPU fan header. If you face the CPU fan error, it might be because the header you are using is faulty.
The best thing to do in this case is to try another header. Also, ensure the fan is connected to the correct location (i.e., the fan header).
5. Check other fans
Sometimes, you need to verify if your CPU fan is working well. To do this, you need to try other fans compatible with your PC.
Just make sure you connect it to the header and that the area is well-ventilated.
6. Replace the CPU fan
If the fixes above fail to solve the CPU fan error, you might need to go for broke and replace the fan. This is especially true if you tested your PC with other fans, and they worked without error.
The only thing you need to take care of is the compatibility of the fan with your PC and that you get the connection right.
What will happen if the CPU fan fails?
Central processing units that have dead fans willoverheat. When a computer’s central processing unit (CPU) gets too hot, there are normally built-in safeguards that will either shut it down or slow it down to prevent it from exploding.
However, suppose the computer protections fail or don’t kick in quickly enough. In that case, the central processing unit (CPU) could reach temperatures above its maximum operating temperature and burn out.
