How to Test Your Laptop Fans

How do you check if your laptop fan is working? There are a few simple tests you can run. Here’s how to test your laptop fans and ensure they function properly.

  1. Check the air vents. The first thing you’ll want to do is take a look at the air vents on your laptop. If dust or debris is blocking the vents, this can impede airflow and cause your fan to work harder than it needs to. Cleaning the air vents will help ensure that your fan can operate properly.
  2. Listen for fan noise. Another way to check if your laptop’s fan is working is to listen to it. If you hear the fan running, this is a good sign that it’s functioning properly.
  3. Feel for airflow. Another way to test your laptop fan is to feel for airflow coming from the air vents. The fan is working if you can feel a strong flow of air.
  4. Check the fan speed. If your laptop has a fan control setting in the BIOS, you can check the fan speed to ensure that it’s running at the proper rate.
  5. Run a system diagnostic. Finally, if you’re still unsure whether your laptop’s fan is working correctly, you can run a system diagnostic. Doing so will test components in your laptop, including the fan, to ensure they’re functioning correctly.
