If you’re an Asus desktop user, you might have encountered a “CPU Fan Error” message during startup. This error message indicates that the computer’s BIOS cannot detect the CPU fan’s functioning. It’s a common issue; fortunately, it’s easy to fix. This post’ll guide you through the steps to fix the Asus CPU Fan Error.

What Causes Asus CPU Fan Error? Before we delve into the solutions, let’s understand the reasons behind the Asus CPU Fan Error.

Dust build-up – One of the most common causes of the Asus CPU Fan Error is dust build-up in the fan. Over time, dust accumulates inside the computer, clogging the fan and preventing it from spinning.
Loose connection – Another reason for the CPU Fan Error could be a loose connection between the fan and the motherboard. The motherboard may not detect the fan’s functioning if the connection is not secure.
Faulty fan – In some cases, the CPU fan may be faulty or damaged, causing the BIOS to fail to detect it.

Now that we’ve understood the possible causes, let’s move on to the solutions.

Solution 1 CPU Fan Error:

Clean the CPU Fan As mentioned earlier, dust build-up in the CPU fan can cause the Asus CPU Fan Error. Cleaning the fan is the easiest solution to this problem. Here’s how you can clean your CPU fan:

Please turn off your computer/PC and unplug it from the power source.
Open the computer case and locate the CPU fan.
Use compressed air to blow out the dust from the fan. Hold the can upright to prevent moisture from entering the fan.
You can also use a soft brush to clean the fan blades.
Once you’ve cleaned the fan, plug it back in and restart your computer.

Please turn off your computer/PC and unplug it from the power source.
Open the computer case and locate the fan’s connection to the motherboard.
Ensure the fan’s power cable is securely connected to the motherboard’s CPU fan header. You can also try disconnecting and reconnecting the cable to ensure a secure connection.
Once you’ve checked and secured the connection, plug your computer back in and restart it.

Please turn off your computer/PC and unplug it from the power source.
Open the computer case and locate the CPU fan.
Disconnect the fan’s power cable from the motherboard’s CPU fan header.
Remove the fan from the heatsink by unscrewing it.
Replace the old fan with a new one, matching the fan’s size and power requirements with the previous fan.
Secure the new fan in place by screwing it onto the heatsink.
Reconnect the fan’s power cable to the motherboard’s CPU fan header.
Once you’ve replaced the fan, plug your computer back in and restart it.

Conclusion:
