Error with the CPU Fan! To continue with the startup, press F1! or Error: The CPU Fan Is Broken!
Users of ASUS and American Megatrends motherboards may get the problem at the starting of their Windows PC or laptop.
When a CPU fan issue occurs, the computer usually shuts down. This warning indicates that the CPU may be overheating. However, in certain instances, even though the fan is operating, the CPU fan error occurs.
We will explain what this issue is, why it occurs, and how to quickly repair it once and for all in this post.
How Does the CPU Fan Error Show Up?
The ASUS fan issue usually occurs at startup or during bootup. The error message may change from time to time, but you will always see this text.
- “Error: The CPU fan has shut down!”
- “CPU Fan Error” is a term used to describe a problem with
What Causes ASUS CPU Fan Startup Errors?
This error indicates that the motherboard’s safety function is operational. If the fans aren’t spinning correctly, the CPU temperature may rise, potentially damaging internal components.
This error is caused by the most frequent reason.
- The CPU fan is not correctly linked to the motherboard’s cpu fan header.
- Incorrect BIOS fan settings.
- The fan RPM was slowed by dust and debris.
- The fan is permanently broken.
How to Resolve the CPU Fan Error During Boot/Startup
Because this issue may be caused by hardware or software, the solutions will vary depending on the user.
Users of the Corsair or NZXT Kraken AIO CPU cooler connect the incorrect pump header in the motherboard by accident. As a result, you’ll get this error message.
1. Verify that the CPU fan is properly connected.
This fan issue occurs on Asus and Megatrends motherboards because the cpu fan header is either disconnected or inserted into the incorrect header.
- Please double-check that the CPU FAN is placed in the correct location on the motherboard and tighten the screws.
- If you’re using a water cooler, such as the H100i or H100i V2, and the fan speed issue persists, connect the hydero pump to the AIO PUMP connector (rather than the CHA FAN header).
- Make sure the CPU FAN cable is connected to the CPU FAN connection rather than the CHA FAN.
Fix 2: Lower the CPU Fan Speed Limit
Is the CPU fan spinning at the correct RPM? In most cases, the Asus fan error indicates that the fan is underperforming in terms of RPM.
The system may not be able to properly identify users who are using a NZXT, Corsair fan with a lower rotation speed.
In the BIOS, set the “CPU Fan Speed Low Limit” to 200 RPM.
Follow these procedures to modify the lower fan speed limit:
- Upon starting, press F1, F10, or Delete to enter BIOS.
- Go to Advanced Settings and find the CPU fan settings. (Depending on the model of your motherboard, this section may differ.)
- The CPU fan RPM notifications are controlled by a setting. 600 RPM should be the default setting (Revolutions Per Minute).
- Reduce the default RPM from 300 to 450 and save the modifications.
- Exit the BIOS and restart the computer.
3. In the ASUS BIOS, disable CPU Fan Speed Monitoring.
If the CPU fan problem appears but the fan is operational, you may turn off the alert. Take the following steps:
- Enter the BIOS.
- Go to the Advanced options described before.
- In the Monitoring (Monitor) section, look for the Monitoring (Monitor) section.
- Ignore the CPU Fan Speed and Confirm the adjustments.
4. Update the BIOS
The most common cause of fan problem on ASUS and Megatrends is a faulty BIOS program. You’re set to go if you just upgrade the BIOS to the most recent version.
5. In the BIOS, check the fan settings.
If you’ve recently updated your BIOS settings, this may be the source of the Asus fan problem.
- BIOS should be opened.
- Advanced Options should be selected.
- Select the Hardware Monitor option.
- The CPU Fan option may be found there.
- Active Heat Sink and Fan Duct with Fan should be enabled.
- Passive Heat Sink and Fan Duct without Fan should be disabled.
- Exit BIOS after saving your modifications.
Replace the CPU fan, if necessary.
If the message still appears on the Asus motherboard when it boots up, it may be a hardware issue. You’ll need to purchase a new CPU fan to replace the damaged one.

Fix #7: Ensure that the CPU Fan is in good working order.
The enemy of computer hardware is dust. When dust accumulates within, it prevents the fins from rotating at their optimal pace.
The CPu fans should be cleaned on a regular basis. To do so, switch off the computer, disconnect the power cord, and blow the dust away with canned air.
If one fan header fails, modern motherboards feature several fan headers. If it doesn’t work, try connecting the fan into a different slot. This may help with the CPU fan issue.
The asus cpu fan error but fan spinning is a problem that many Asus users have been having. There are several fixes to fix the issue, including updating the BIOS and replacing the CPU fan.
