Occasionally, your Asus will display the CPU fan error message on boot even when your fan is functioning. It’s a feature added to safeguard your motherboard from overheating.
You can disable the safeguard feature but only after ruling out all other causes of CPU fan failure.
Don’t disable the safeguard if your CPU fan is genuinely failing. If you do, the CPU and motherboard will continue overheating, leading to severe damage.
To disable CPU fan error Asus, boot in BIOS, select monitor, and open fan speed monitor. This will grant you access to all fans in your Asus PC.
You can select the fan you wish to disable monitoring. Once you select the fan, you’ll get the option to ignore or monitor. Choose the former to disable the annoying CPU fan error message.
Reboot your PC to confirm if the error message is still appearing.
5 Methods to Disable CPU Fan Error Asus
If disabling CPU monitoring doesn’t solve your error problem or reduce overheating issue, try these alternatives:
Check that Fan is Connected Properly
A poor CPU fan connection can trigger the error notification. You’ll need to remove some screws to access the fan and check that it’s on the right side.
The screws securing it in place should also be tight.
Clean CPU Fan
If you started with the first step, you’ll still have your CPU fan open.
Instead of closing it after confirming that everything is installed correctly, clean the fan to remove dust and dirt buildup. Use canned or compressed air for this.
Update BIOS
You’ll rarely need to update BIOS unless in instances such as this. Updating BIOS can fix the CPU fan error Asus. However, before updating the BIOS, check if the current version is up to date.
You can check BIOS version by typing ‘cmd’ in the search bar. Open Command Prompt app, type ‘wmic bios get smbiosbiosversion,’ and hit enter. Check the version and update if necessary.
How do you update BIOS? Visit the manufacturer’s website and search for current BIOS versions in the Support or Download section. Download your preferred version and unzip it.
Open the readme file to read the update instructions and other recommendations. You’ll probably need a BIOS-flashing tool or update it from a USB file.
If it’s the BIOS-flashing option, check the readme file for recommendation and follow the instructions as detailed in the manual.
Lower Fan RPM
Occasionally, your CPU fan will display errors because it’s underperforming. Boot into BIOS to access speed settings by restarting your computer and pressing F2, F12, or F10 as it powers up.
Select CPU fan settings to access the advanced setting menu. Once here, look for CPU fan control and lower the default RPM.
For example, if the default RPM is 600, you can lower it to 300 or 200 RPM. Save the changes and exit BIOS. Boot your PC and confirm that the error is disabled.
Replace the Fan
If all attempts to disable the CPU fan error fail, you can replace it. Your CPU fan is likely faulty, and changing its settings won’t resolve anything.
You can update BIOS settings or lower RPM as much as you’d like, but neither will fix damaged hardware.
Try connecting a functioning CPU fan to check whether it’s a hardware issue. If it runs, replace your current CPU fan.
Can You Disable CPU Fan?
Can you completely disable the fan if the CPU fan error becomes annoying? Yes, completely disabling the fan is possible.
However, if you do, brace yourself for expensive repairs. The CPU fan is needed to cool the CPU; thus, operating your PC without the fan will turn it into a sauna.
The PC will gradually overheat, and since it lacks CPU safeguards, the temperatures will rise above 80 degrees Celsius and fry internal components.
If the heat doesn’t damage the components, it’ll degrade and reduce their lifespans. Disabling the fan is a pointless endeavour with high risks.
But if you insist, access BIOS settings to turn off the fan. Navigate to the system monitor section and select CPU fan. Use the plus or minus keys to alter CPU fan status to disabled.
Save, exit setup, and boot PC.
Final Thoughts
Typically, when your PC displays the CPU fan error, it will shut down immediately. This is a CPU safeguard aimed at protecting internal components from overheating.
Therefore, instead of attempting to disable the error, focus on solutions.
Your PC is notifying you that the CPU is malfunctioning. Your first thoughts should revolve around CPU fan error causes and remedies.
Don’t attempt to disable the message without understanding the trigger.
The error message could be notifying you of impending damage; thus, disabling the error and fan at your own risk.
Alternatively, consult a specialist for diagnostics and repairs. It’s likely cheaper than replacing internal components such as CPU and motherboard.
