How to Make a Laptop Fan Quieter

Dust and debris can easily and quickly accumulate on and around a laptop fan, causing it to run less effectively. A clogged fan can cause your laptop to overheat, which can potentially damage your computer's motherboard. If your fan frequently emits a loud whirring noise, even when you are not running memory-intensive applications, then cleaning the fan is your best bet for a quieter laptop.

Step 1

Power off your laptop and remove the AC adapter (the cord that goes into the wall outlet). Close your laptop's lid and turn the computer over so the bottom is facing upright.

Step 2

Put on an anti-static wrist-strap or touch an unpainted metal surface to discharge any static electricity. Anti-static wrist straps can be purchased at electronics stores.

Step 3

Release the lever or levers holding your laptop's battery in place, then pull the battery free with your hands and set it aside.

Step 4

Shine a flashlight into the airway vents on your computer to locate the fan blades. Place a toothpick or cotton swab in between two of the fan blades to hold the fan in place.

Step 5

Attach the thin rubber or plastic tube that was included with your can of compressed air to the nozzle of the can. Angle the can so the tube is directly above the fan vent. Do not hold the can upside down, and do not shake the can.

Step 6

Spray around the fan blades to expel any air and debris from the vents. Depending on your laptop's model, you may also need to spray vents on the side of the laptop.

Step 7

Wipe any dust or debris off the surface of the laptop.

Place the battery back into the laptop and lock it in place. Reconnect the AC adapter and power on the computer. Not only should the fan run quieter, but the laptop should stay cooler longer.


  • Do not spray your hands or any other part of your body with the can of compressed air, as it can cause frostbite.
  • Do not spray the compressed air in between the vents without first securing the fan with a toothpick or cotton swab. The compressed air can cause the blades to spin too fast, damaging the fan.


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