Checking if Fans Are Working on a Laptop
If you don’t know how to check if the fans are working on your laptop, our following 3 step-by-step methods will help you accomplish this task easily.
Method #1: Listening to the Sound
Most of the time, you can check if your laptop fans are working how they are supposed to be by hearing their whirring sound in the following way.
- Turn on your laptop.
- Run a resource-heavy app.
- Put your ears closer to the fan vent (the location of the fan vent can vary with the laptop model).
- Listen to the sound of your fans to check if they are working.
It might take 10 to 20 seconds for your fans to make the functional noise after running a resource-heavy program, so wait patiently to hear the sound.
Method #2: Feeling the Air
If you can’t hear a sound, you can also check if your laptop fans are working by feeling the pressure of the air coming out of the fan vents in the following way.
- Turn on your laptop.
- Locate the fan side vents on your laptop.
- Place your hand or a piece of paper in front of the vents.
- Launch a resource-demanding program.
Your laptop fans work fine if the paper is slightly moved or blown by the air from the vent or you feel faint, warm air on your hands.
Method #3: Using Third-Party Software
With these steps, you can also check the operational status of your laptop fans and much more using third-party software.
- Open a browser of your choice on your laptop and head to the SpeedFan website.
- Click the “Download” link to download the program on your PC.
- Click the downloaded file to install the SpeedFan software on your computer using on-screen prompts.
- Open SpeedFan.
- Check the fans and their speed below “CPU Usage” on the main interfaces to ensure they are working on your laptop.

How To Increase the Fan Speed on a Laptop
If your laptop fans work slower than your preference, try the following methods to increase their speed.
Method #1: Using the Control Panel
To increase the speed of slow-working fans, open the Control Panel on your Windows laptop and follow these steps.

In the “Power Options” pop-up window, scroll and locate “Process power management”. Next, click the “+” beside it to expand the option, click “+” next to “System cooling policy”, and select “Active” on the “On battery” and “Plugged in” options.
Click “Apply” and then “OK” to make the changes and increase the fan speed on your laptop.
Method #2: Using BIOS Setup Utility
Most laptops allow users to change the fan’s speed if they are working too slowly in the BIOS menu using these steps.
- Shut down your laptop and turn it on again.
- Press either the F10, F2, F1, or Del keys, based on your laptop’s model, to enter the BIOS setup utility.
