How to Quiet a Laptop Fan
Laptop computer fans need to be cleaned to reduce noise. (laptop computer image by Photoeyes from

A laptop computer has up to four separate fans to keep the central processing unit (CPU) from overheating and damaging internal parts. Over time, debris and dust can accumulate on the fan, making it noisy. It is important to remove the build-up on the fan as soon as possible so the fan does not overheat. Adding an oil or a lubricant to the fan can quiet the fan noise.

Skill level:

Things you need

  • Phillips screwdriver
  • Specialised computer vacuum
  • Lint-free cloth
  • Lightweight silicone lubricant

  1. 1

    Power off the laptop as usual and unplug the computer from the electrical socket. Turn the computer so it is upside down. Take out the screws from the bottom panel with a Phillips screwdriver. Pull off the panel from the laptop.

  2. 2

    Blast off dust or debris from the computer fan with a special computer vacuum. Take as much dust off as you can. Wipe off any stubborn particles with a lint-free cloth. Avoid bumping the motherboard or you could harm it.

  3. 3

    Push the panel back into place and line up the openings in the panel with the screw holes. Insert the screws into the holes and tighten with a screwdriver. Flip the computer over so it is right-side up. Plug the cord into the outlet and reboot the computer. Check the fan noise. If it is still quite noisy, then move on to the next section.

  1. 1

    Shut down the computer as you typically would. Pull the cord out of the outlet. Turn the computer over so it is upside down. Remove the screws in the bottom cover with a Phillips screwdriver and take off the cover. Purchase a silicone lubricant to use on the fan to quiet the noise.

  2. 2

    Leave one drop of silicone lubricant on the base of the fan or section holding the fan in place. Spread the lubricant around the base with your index finger.

  3. 3

    Slide the bottom panel back into the opening and tighten the screws with a Phillips screwdriver. Power up the computer and check the fan noise. If it is still noisy, place one more drop of lubricant on the fan base.

Tips and warnings

  • Avoid using a regular vacuum on the laptop and use a vacuum specifically designed for a computer. Normal vacuums have static electricity and could ruin the computer's internal parts.
  • If you cannot use a special vacuum, use a can of compressed air to clean the fan. Position the can straight up and spray the air into the fan or liquid could spray out.
