Sometimes you may find that your laptop fan runs loudly, and you can’t focus on the thing you are working on. Usually, it is caused by two factors.

  1. Dust: Even though your laptop is compact, it is still prone to accumulation of dust. The clogged dust can do harm to your laptop’s system which causes it to run hot and noisy.
  2. Overheating: The cooling fan running at a fast and the non-stop rate could be another reason why your laptop fan is so noisy. It’s firing up or working harder than usual when it needs to get rid of heat or when it’s under the extreme workload.

Here are 4 ways to fix the noisy laptop fan.

Dust and debris can easily and quickly accumulate on and around a laptop fan. You’ll need to dust the laptop cooling system at least once a year to prevent any damage or degradation. You can try this when your laptop is too noisy.

Step 1: Power off your laptop and remove the cord that goes into the wall outlet.

Step 2: To protect yourself, you need to put on an anti-static wrist-strap or touch an unpainted metal surface to discharge any static electricity.

Tip: Anti-static wrist straps can be purchased at electronics stores.

Step 3: Remove the laptop battery.

Step 4: Find the fan blades from the airway vents and place a toothpick or cotton swab between two fan blades to hold the fan in place.

Step 5: Attach the plastic tube to the nozzle of the compressed can.

Tip: You can purchase a can of compressed air in the electronics section of almost any major department store.

Step 6: Wipe any dust or debris off the surface of the laptop.

Then you can place the battery back into the laptop and lock it in place. Reconnect power on the computer, and your laptop should run quieter and stay cooler longer.

Warning: Do not touch the compressed air sprayed from the can with your hands or any part of your body, as it can cause frostbite.
