What is the Best Way to Determine If a CPU Fan is Not Spinning?

The CPU fan is an important component that helps keep your computer cool and prevents overheating. However, if your cpu fan seems to be stuck or stationary, it can be a big problem as it will stop circulating air inside the case and may result in a CPU overheating. In this article, we will explore some of the possible reasons why your cpu fan may not be spinning and provide some simple troubleshooting tips to help you resolve it.

Among the most common reasons why your CPU fan may not be spinning is because its power cable has become disconnected from the motherboard. This can happen if it wasn’t properly connected during installation or if the cable has simply come loose over time.

Another common reason is that the fan is obstructed by dust, which can cause it to slow down or even stop working. To fix this, first make sure the fan is clean and free of dust. You can blow it out with a blast of compressed air or use a vacuum cleaner to remove any dust particles that might be obstructing the blades.

You should also make sure that the CPU fan connector is plugged into the correct header on the motherboard. The CPU fan connector is usually labeled as “CPU Fan” or “CPU_FAN” and should never be plugged into a different header that’s marked as “CPU Optional,” “Pump Fan,” or “CHA FAN.” Additionally, if you have your fan set to run at a specific speed through the BIOS settings, it’s important to ensure that the BIOS has been updated to the latest version.
