How To Fix CPU Fan Error In Asus Motherboard

The computer you have is probably your pride and joy, but it’s not perfect. There are always some little things that need fixing here and there. But what do you do when your motherboard fan isn’t working?

Recently my motherboard broke, and I was running out of options to fix it. So I researched the internet and found out how to fix CPU Fan Error on Asus Motherboard!

How to Fix CPU Fan Error in Asus Motherboard

If you’re experiencing problems with your CPU fan, you can do a few things to try and fix the issue. 

First, make sure that the power supply is working properly. If the power supply is fine, check to see if any of the connectors on the motherboard or CPU are loose.

Once you’ve determined that nothing is wrong with the hardware, try resetting the BIOS to default settings. This will clear out any old configurations and should help get your fan running properly again.

What Causes Fan Error in ASUS Motherboard

ASUS motherboards are well known for their overclocking capabilities and overall performance. However, some users have experienced fan errors on their ASUS motherboards due to how ASUS’s fan controller works.

This issue can occur when the user attempts to overclock their CPU or when they install an aftermarket cooler.

When these drastic changes are made to the motherboard’s cooling system, it can cause the fan controller to malfunction. This results in a high-frequency spin of the CPU fan, which can cause noise and, ultimately, a Fan Error.

You can do several things to try and fix your Fan Error on an ASUS motherboard.

First, check to ensure that your CPU is properly seated in your motherboard’s socket and that there is no obstruction between the heatsink and processor. If these steps don’t work, you may need to replace your motherboard or processor.

How to Solve CPU Fan Error on ASUS Motherboard

ASUS motherboards have a feature that allows you to check and see if your CPU fan is working. To do this, open the BIOS by pressing the DEL key during startup and then go to the Advanced tab.

You will find a CPU Fan Test item under the Hardware Monitor section. By clicking on it, you will be taken to a screen where you can select one of three options: Check Status, Check Current Status or Clear All. 

If your motherboard has an attached graphics card, make sure it’s powered off before checking the status of your CPU fan.

The graphics card uses a lot of power and could interfere with the motherboard’s ability to detect whether or not your CPU fan is working properly.

To check the status of your CPU fan, click on Check Status. This will take you to a screen where you can see information about your CPU fans, such as speed and voltage. 

If your motherboard doesn’t have an attached graphics card, or if you want to clear all of the information on the screen, including the status of your CPU fan, click on Clear All.

What Happens if You Don’t Fix the Error?

If you don’t fix the CPU fan error in the Asus motherboard, the computer will not be able to function and may even crash. Here’s what you need to do:

  1. When you first notice the fan error, power off your computer and disconnect all cables.
  2. Remove the motherboard cover (if applicable) and locate the CPU Fan header.
  3. Using a flathead screwdriver, remove the four screws that hold down the header-cover assembly.
  4. Carefully pull up the header-cover assembly and disconnect both connectors from the CPU Fan header. The connector should come free easily if it is properly connected. If it is not connected properly, gently push down on one side of the connector while pulling up on the other until it slides out of its socket.
  5. Verify that both connectors are correctly disconnected by looking at them from different angles; if they are not connected properly, reattach them using a new set of screws and connector clips (depending on which type of connector is being used).
  6. Reinstall the header-cover assembly by replacing four screws and reconnecting both connectors to their respective sockets on the CPU Fan header.

Common Mistakes That Cause a CPU Fan Error

A CPU fan error is usually caused by one of the following:

1. Insufficient cooling – Ensure your motherboard has enough cooling and the fan is running at full speed. If the CPU is overclocked, make sure it is properly cooled first.

2. Dirty or incorrectly installed heatsink or fan – Clean it with a mild soap and water solution and dry it off completely before installing it again. Also, ensure the contact surfaces between the CPU and heatsink are clean.

3. Damaged or malfunctioning motherboard – If you have replaced your motherboard, install it properly to avoid any damage to the CPU or other components on the motherboard.

Frequently Asked Questions

What are the causes of CPU fan errors on Asus motherboards?

Asus motherboards use a variety of sensors and hardware to monitor CPU temperature and activity. If one or more of these sensors become corrupted, the motherboard may interpret this as an abnormally high CPU temperature, which may cause the fan to run continuously at full speed. In some cases, this may also result in a fan error message being displayed on the screen.

How can I fix the CPU fan error on an Asus motherboard?

The first step is to determine which sensor is causing the problem. If it’s one of the three main temperature sensors, then simply replacing that sensor should fix the issue. However, in many cases, only one or two of these sensors are likely faulty, so you’ll need to try other fixes before resorting to replacement.

Conclusion

CPU fan error is one of the most common issues plaguing Asus motherboards. If you’re experiencing this problem, don’t panic — there are a few things you can do to try and fix it.

In this article, we have gone over some of the most common causes of CPU fan error on Asus motherboards and offer a few solutions. Hopefully, by following these steps, you can get your motherboard up and running without having to send it in for repairs or replacement.
