How To Disable CPU Fan Error Asus: A Complete Guide For Users

How To Disable CPU Fan Error Asus

The CPU fan error on Asus motherboards can be a frustrating issue that impacts the performance and stability of your computer. When your system detects a problem with the CPU fan’s operation, it often triggers an error message and may even prevent your computer from booting up. In this article, we will guide you through disabling the CPU fan error on Asus motherboards. We’ll explore the root causes of this issue, provide troubleshooting steps, and offer valuable insights on ensuring your CPU remains adequately cooled while addressing the error effectively. Don’t let the CPU fan error disrupt your computing experience; let’s start resolving it.

How To Disable CPU Fan Error Asus?

Access the BIOS Setup

Begin by restarting your computer. During the boot-up process, you need to enter the BIOS setup. The key to access the BIOS varies based on your motherboard model but is commonly one of the following: Delete, F2, or F12. Refer to your motherboard’s manual or watch for on-screen instructions to determine the correct key for your system.

Navigate to the Advanced Tab

Once you’ve entered the BIOS setup, you’ll typically find various tabs and menus. Navigate to the “Advanced” or “Monitor” tab. Remember that the naming and structure of these tabs can vary depending on your motherboard’s specific BIOS version.

Locate the CPU Fan Settings

Within the “Advanced” or “Monitor” tab, search for the section that deals with fan settings or hardware monitoring. Under this section, you should encounter options related to CPU fan control and alerts.

Adjust Fan Speed Control

Look for the setting that allows you to control the CPU fan speed. This setting might be labeled “CPU Fan Speed Control,” “CPU Q-Fan Control,” or something similar. It’s usually set to “Automatic” by default. Change this setting to “Ignore” or “Disabled.” This adjustment informs the BIOS to stop monitoring the CPU fan’s speed.

Disable CPU Fan Error Alert

In the same section where you adjusted the fan speed control, there should be an option related to CPU fan error alerts. Disable this option to prevent the motherboard from generating error messages concerning the CPU fan. The name of this option can vary but often includes terms like “CPU Fan Error Alert” or “CPU Fan Error Warning.”

Save and Exit

After making these changes, you must save your BIOS settings and exit. The key combination or process to do this may vary slightly between motherboards, but you’ll generally find it by pressing the F10 key or following on-screen prompts. Saving and exiting will apply your changes and reboot your computer.

Monitor CPU Temperature

With the CPU fan error alert disabled, it’s vital to keep a close eye on your CPU’s temperature. When the BIOS no longer controls the fan speed, it becomes your responsibility to ensure the CPU stays adequately cooled. You can use monitoring software like HWMonitor or Asus’s AI Suite to monitor your CPU’s temperature and adjust fan settings.

Consider Long-Term Solutions

While disabling the CPU fan error alert resolves the immediate issue, it’s a temporary fix. It’s essential to address the root cause of the problem. If your CPU fan isn’t functioning correctly or not providing sufficient cooling, consider replacing the fan or upgrading to a more efficient cooling solution for improved long-term performance and system reliability.

What Causes The CPU Fan Error On Asus Motherboards?

The “CPU fan error” on Asus motherboards typically occurs when the motherboard’s BIOS (Basic Input/Output System) detects an issue with the CPU (Central Processing Unit) fan or the CPU cooling system. Several factors can trigger this error:

Disconnected or Malfunctioning Fan: If the CPU fan is not correctly connected to the motherboard or fails, the BIOS may not receive the expected signals from the fan, leading to the error.

Fan Speed Below Threshold: Some motherboards are configured to monitor the CPU fan’s speed. If the fan speed falls below a predefined threshold, the BIOS may assume a problem and trigger the error. This could happen if the fan is dirty, obstructed, or malfunctioning.

BIOS Settings: Incorrect BIOS settings related to fan control can also cause the CPU fan error. For example, if the BIOS is set to monitor the CPU fan but the fan is not present, or if the BIOS is set to control the fan speed and the fan is not responding as expected, an error can occur.

Firmware Bugs: In some cases, firmware bugs or issues in the motherboard’s BIOS can trigger false CPU fan errors. Updating the motherboard’s BIOS to the latest version can sometimes resolve such issues.

Wiring and Connections: Problems with the wiring or connections between the CPU fan and the motherboard can also lead to errors. A loose or damaged connector can prevent the fan from sending the necessary signals to the motherboard.

Faulty Temperature Sensors: Some motherboards use temperature sensors to gauge CPU temperature and adjust fan speed accordingly. If these sensors malfunction or report inaccurate readings, it can lead to fan errors.

Inadequate Cooling: If the CPU fan and cooling system cannot cool the CPU adequately, it may trigger the error as a safety measure. This can happen if the thermal paste between the CPU and the heat sink is improperly applied or if the heat sink itself needs to be fixed.

Final Words

The “CPU fan error” on Asus motherboards is a common issue that arises due to various factors, including disconnected or malfunctioning fans, incorrect BIOS settings, firmware bugs, and more. It’s a critical error as it can lead to overheating and system instability. While disabling the CPU fan error alert may provide a temporary solution to allow your computer to boot, it’s crucial to address the underlying problem for long-term system health. Regularly monitor your CPU temperature using reliable software, maintain proper cooling components, and consider seeking professional help if necessary.


What is a CPU fan error on Asus motherboards?

A CPU fan error on Asus motherboards is an error message that appears during the computer’s boot-up process when the motherboard detects a problem with the CPU (Central Processing Unit) fan or the CPU cooling system.

Why is it important to address the CPU fan error?

It’s essential to address the CPU fan error because it indicates a potential issue with the cooling system. Ignoring the error can lead to overheating, which may cause damage to the CPU and lead to system instability or crashes.

How can I access the BIOS setup on my Asus motherboard?

To access the BIOS setup, restart your computer and press a specific key during the boot-up process. Standard keys for accessing the BIOS include Delete, F2, or F12. The exact key can vary depending on your motherboard model.
