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 is unable to detect the CPU fan’s functioning. It’s a common issue, and fortunately, it’s easy to fix. In this post, we’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 first understand the reasons behind the Asus CPU Fan Error.

1. 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.
2. Loose connection – Another reason for the CPU Fan Error could be a loose connection between the fan and the motherboard. If the connection is not secure, the motherboard may not detect the fan’s functioning.
