You know, the CPU fan error usually pops up when you’re booting up your computer, not when you’re already using it.
So, it’s not like it will interrupt your Netflix binge or anything! The message might look a little different depending on your computer, but it’ll probably say something like:
- Error: CPU Fan Has Failed!
- CPU Fan Error”
Understanding the Causes of CPU Fan Errors in ASUS Motherboards on Startup – 4 Vital Steps!
when you see that ASUS CPU fan error pop up during startup, it’s a good thing in a way. It means that the motherboard’s safety feature is doing its job, ensuring everything stays calm and happy. But if those fans aren’t spinning like they should, it could spell trouble for your CPU’s temperature, which might end up damaging some of the internal hardware.
Now, let’s talk about what usually causes this error:
- CPU fan isn’t connected correctly: Sometimes, it’s as simple as ensuring the CPU fan is snugly connected to the motherboard’s cpu_fan header.
- Incorrect fan settings in BIOS: If the settings in the BIOS aren’t quite right, it can mess with the fan’s performance and trigger the error.
- Dust and debris: Dust bunnies and gunk can slow down the fan’s RPM (rotations per minute), causing it to struggle.
- Broken fan: If the fan is kaput and won’t spin, well, that’s a pretty clear-cut reason for the error.
- PC overheating: Of course, if your computer’s running hotter than a summer day in the desert, that can trigger the CPU fan error, too.

1. Move Your PC To a Cool Place:
First things first, if your computer is sitting in a spot where it’s soaking up all that heat from the sun or just generally getting too toasty, it might shut down on its own, even if the fan is doing its job. So, my advice? Give your computer a change of scenery. Pop it in a cooler room and keep it out of direct sunlight during the day.
2. Check Your CPU Fan:
While you’ve got your computer open, peek at those fans. Sometimes, they can get a bit wonky or decide to go on a little adventure out of position. Depending on the type of fan you’ve got, you might need to bust out a screwdriver or a bit of glue to get them firmly back in place.
3. Try Another CPU Fan Header:
If you’ve got more than one CPU fan slot on your motherboard, it’s worth giving another one a whirl. Sometimes, just switching things up a bit and plugging the fan into a different slot can magically make that CPU Fan Error In ASUS Motherboards disappear.
4. Check Your Connections:
One of the main reasons for this error is that something’s not quite right with the CPU fan connection. Either nothing’s plugged into the CPU_fan header, or it’s in the wrong spot altogether. Make sure the CPU fan is installed in the correct position on the motherboard, and don’t forget to tighten those screws for a snug fit. And hey, if you’re using a water cooler like the H100i or H100i V2 and you’re still getting that fan speed error, try connecting the Hydro pump to the AIO_PUMP header instead of the CHA_FAN.
5. Adjust the Fan Speed:
Is your CPU fan spinning at the right speed? Sometimes, the error message is a gentle nudge telling you that your fan’s RPM is a bit off. This can be especially tricky if you’re using NZXT or Corsair fans with lower revolution speeds. To tweak the fan speed lower limit, you’ll need to dive into your BIOS settings. Here’s how:
- Press F1, F10, or Delete key upon startup to enter BIOS.
- Navigate to the CPU fan settings in the Advanced Settings section (the exact location may vary depending on your motherboard model).
- Look for the setting that controls the CPU fan RPM alerts. The default value is usually around 600 RPM.
- Lower the default to a range between 300 RPM to 450 RPM.
- Save your changes, exit BIOS, and boot up your system.
6. Disable CPU Fan Speed Monitoring in ASUS BIOS:
Sometimes, the error message pops up even when your fans do their job just fine. Here’s how to fix it:
- Boot into your BIOS.
- Head over to the Advanced settings.
- Look for the Monitoring (or Monitor) section.
- Change the CPU Fan Speed setting to Ignore and confirm your changes.
7. Update the BIOS:
BIOS software glitches often cause CPU fan errors on ASUS motherboards. So, why not update it to the latest version? It does the trick and saves you a lot of headaches.
8. Check Fan Settings in Your BIOS:
If you’ve recently tinkered with your BIOS settings, that could be why you’re seeing that pesky fan error. Here’s what you can do to set things right:
- Open up your BIOS settings.
- Navigate to the Advanced Settings.
- Look for the Hardware Monitor section.
- Find the CPU Fan option.
- Ensure that the Active Heat Sink and Fan Duct are enabled with a fan and disable the Passive Heat Sink and Fan Duct without a Fan.
- Save your changes and exit BIOS.
9. Replace Your CPU’s Fan:

If you’ve tried everything and that error message still haunts you, it might be time to face the music and replace your CPU’s fan. Sometimes, software tweaks can’t fix hardware problems, and that’s okay. Grab yourself a new fan, swap it out for the old one, and you should be ready.
10. Clean Your CPU’s Fan:
Let’s face it, dust is the arch-nemesis of computer hardware. When it builds up inside your CPU’s fan, it can throw a wrench in the works by blocking those fins from spinning at their optimal speed. The solution? Regular cleaning sessions. Simply power down your PC, unplug the power cable, and grab some canned air. Give that fan an excellent blast to blow away all that pesky dust, and you’ll be amazed at how much smoother your system runs afterwards.
11. Try an Alternate CPU Fan Header:
Nowadays, most motherboards come equipped with multiple fan headers. If one seems to be on the fritz, why not give another one a shot? Simply plug your CPU fan into a different slot, and cross your fingers. It could be the magic fix you’ve been searching for to banish that pesky CPU fan error.
With a little elbow grease and some trial and error, I’m confident you’ll be able to tackle that CPU fan error head-on and get your system running smoothly again in no time. You’ve got this!
