This blog post will guide you through the steps to test a laptop cooling fan and ensure that it’s working correctly to avoid frustrating computer crashes and prolong the life of your device. Get ready to keep calm under pressure!

To test your laptop’s cooling fan, shut down the machine and unplug the power cord. Remove the battery if there is one installed. Open the laptop case and locate the fan. It is a large white object mounted on a metal frame. If it’s not already attached, unscrew the fan blade from its mounting disk and hold it up to your laptop so that you can see the blades.

If your Laptop Cooling Fan has a heat pipe, you’ll also see a black pipe running from the CPU to the fan. Reconnect the power cord, replace the battery if there is one, and turn on the machine. Watch as the fan starts spinning immediately. Check to see how loud it is by pressing your ear up against it. The fan should be spinning at a moderate speed, with no more than a whisper coming from it. If it’s too loud, you can try tightening or loosening one of the screws holding the mounting disk.

To test your laptop cooling fan, you will need the following:

  • A digital multimeter
  • A laptop
  • Cooling Fan Test Board (available online)
  • Large plastic zip bag
  • A piece of cardboard or wood
  • Tape measure or ruler
  • Screwdriver or any large flathead screwdriver

First, you’ll need to remove the laptop’s battery. Then, unplug the power cord and remove any external storage devices. Next, open the laptop case. There are usually two screws that hold the fan in place; remove them. Next, use a flashlight to see if there is an orange or green light on the fan motor. If there is no light, the fan is not working, and you’ll need to replace it. If there is an orange or green light, the fan is working but needs to be replaced.

  • Start by unplugging all the cables from the laptop and the Cooling Fan Test Board. Leave the power cord plugged in, however. You may need to troubleshoot that separately if there are still power supply issues. 
  • Open up the laptop case and locate the cooling fan(s). The fan on most laptops is located on the computer case’s front right side (or left side). On some older laptops, the fan may be located on top rather than below or on the front right side. Check if an obstruction prevents air from entering or exiting the cooling fan (s). If so, remove any obstructions with a tape measure or ruler before continuing

How to Test a Laptop Cooling Fan

Testing a laptop cooling fan is essential to keeping your computer running smoothly. By testing the fan, you can determine if it is malfunctioning and needs replacing. There are two ways to test a laptop cooling fan: by physically checking the fan’s temperature or using a thermal sensor.

If your laptop is overheating, you may need to replace the cooling fan. Testing the fan is an easy way to determine if it’s causing the problem.

To test a cooling fan, turn on your laptop and let it idle for about five minutes. While the laptop is idling, press and hold down the power button until you see a message that says, “Click to enter setup.” Release the power button and wait five more seconds. You should see a blue screen with a cursor in the upper-left corner. Type “alt + F2” and hit Enter.

This will open a command prompt window. At the command prompt, type status” and hit Enter. This will show you the status of your cooling fan. If you have a low-speed or no cooling fan, this will show as 0% or not set, respectively. If your cooling fan is not working, it will show as 100%. If your laptop is overheating because of a faulty cooling fan, you must replace it.

To check the temperature of the laptop cooling fan, physically open up the computer and look at the fan’s temperature. If it is too hot, there is a problem with the cooling fan that needs to be replaced. To use a thermal sensor, first, take off any obstructions from around the cooling fan (if there are any). Then place the thermal sensor on top of the laptop near the fan. The sensor will give you an accurate reading of how much heat is being generated by the fans.

If your laptop is not cooling well, it may be because of a faulty cooling fan. A cooling fan helps circulate air to the computer’s processor and other hot components to keep them cooler. To test if your fan is working, first turn off the power to the laptop and disconnect all cables from the computer.

Next, open the laptop case and locate the cooling fan. If it is not spinning, replace the fan with a new one. Reattach all cables and turn on the power to the laptop. The fan should now start spinning quickly and correctly. If it doesn’t, there is likely a problem with the fan or your computer’s cooling system.

Troubleshooting a Laptop Cooling Fan

If you are having problems with your laptop cooling fan, there are a few things you can do to test and determine if the fan is working correctly. The first step is to unplug the power adapter and ensure no electricity is going to the laptop. Then, check if the fan starts when you plug in the power adapter again. If it does not, the fan may be defective and need replacing.

If your laptop is not cooling correctly, there are a few things you can do to troubleshoot the issue. First, check to see if your laptop has a cooling fan. If it does not, you will need to purchase and install one. Second, make sure that the laptop is plugged in and turned on. Third, try different positions for the laptop on your lap or desk. Finally, try cleaning the fan and heat sink with a damp cloth.

If the fan does start up when plugged in, check to see if it is spinning properly by opening up the laptop case and pointing a light towards the fan. Ensure that the light is shining directly on the fan blade and not reflecting off anything else in the case. If it is not spinning at a proper speed, then you will need to replace the fan.

What to do if the fan fails

If the laptop cooling fan fails, you can test it to determine if it is defective. To test a laptop cooling fan, remove it from the laptop and blow it from a short distance away. If the fan starts spinning, the fan is defective and needs to be replaced. If the fan does not start spinning when blown into, the fan may need to be replaced, but there is no definite way to know for sure.


Testing your laptop cooling fan is essential to ensuring that your computer stays cool and operates at its best. By checking the fan status, you can determine if there is a problem with the cooling system and take appropriate action to remedy it.
