How to Clean the Fan on a Laptop

By Jackie Bailey

To clean your laptop cooling fan, angle a can of compressed air into the cooling vent. Use short bursts of air to remove dust.

Things You'll Need

  • ScrewdriversCotton swabs

Clean the fan on your laptop by spraying the cooling vents with a can of compressed air. You can also take the bottom vent panel off of your laptop and access the fan directly. Either method will help prevent overheating, which can cause a slow laptop or a quick death of it entirely.

Cleaning the Vents With Compressed Air

Step 1

Place your laptop on a clean surface that you don't mind getting dirty.

Tip

Make sure the surface is clean so no added dust gets into the cooling vents and onto the fan.

Step 2

Locate all air vents on the bottom of the laptop. There are side vents, back vents, and vents on the bottom of the laptop. Cooling vents are identified by the copper or black fins inside the vents.

Step 3

Angle the can of compressed air into all of the vents and spray the vents with short bursts of air.

Warning

Never spray compressed air straight into the cooling vents. The pressure from the compressed air can cause the fan to spin fast enough to break it.

Taking the Bottom Panel Off to Clean the Fan

Step 1

Place your laptop on a clean surface that you don't mind getting dirty.

Step 2

Turn your computer off and disconnect the power cord. Turn your laptop over and remove the battery.

Step 3

Locate the removable panel on the under side of the laptop. Remove all of the screws that hold the panel in place. The panel is now easily removed.

Step 4

After the vent panel is removed, you can access the cooling fan. Using the can of compressed air, blow the dust off the fan with short bursts of air.

Warning

Use caution when removing the dust from the fan. If the fan spins too fast from the air pressure, it can break.

Step 5

Replace the panel back on to the laptop and tighten the screws. After the panel is reassembled, attach the battery and power up your laptop.
