How To Clean Laptop Fan At Home?

This section will cover the ways to clean a laptop fan properly. You can follow the steps to avoid making a mess.

External Cleaning Method

It will not be possible to clean an old laptop thoroughly. But for a new laptop under warranty, this method is quite suitable.

There are two holes in the cooling system of any laptop. One draws cold air into the case, and the other pushes out overheated air.

You can find the inlet grille at the bottom of the laptop. On the side of the body, there is an opening for a hot air mixture outlet. How to clean laptop fans at home?

We recommend cleaning the outlet using compressed air. To do this, you need to turn off the laptop before opening it at an angle of 45°. Then, place it on its side on a table or any other stable surface.

Pass the vacuum cleaner tube without a nozzle several times over the ventilation opening for 2-3 minutes. This period will be quite enough to clean the dust from the ventilation grill.

On the other hand, you must clean the inlet by blowing out dust particles under high pressure of clean air. In this case, using compressed air may be most reasonable.

In addition, you must carefully push a long-nose nozzle through the holes of the ventilation grill and press. High-pressure air will start rotating the fan blades, thereby automatically cleaning them.

Why do you need to do that? You will need to unscrew the bolts and remove parts during cleaning your laptop. If you cannot remember, subsequently, the purpose of any of them, look at the recorded video.

Don’t be lazy! You can make it a lot easier for yourself in the future. So let’s get started.

What You Will Need?

  • Phillips screwdriver of suitable size;
  • Container for collecting bolts;
  • Camcorder to avoid incidental situations;
  • Vacuum cleaner and compressed air can;
  • Sterile gloves, soft brushes, cotton swabs;
  • Machine oil.

Unscrew All The Screws On The Bottom Of The Device

How To Process It?

  1. Unplug the laptop and remove the battery.
  2. Using a screwdriver counterclockwise, unscrew all the screws on the bottom of the device.
  3. Conduct a thorough inspection of the internal contents and locate the cooler and heatsink. Visually, any housewife will identify the fan – a device with blades in a square frame. The radiator looks like a box with small grilles.
  4. Unfasten the internal bolts and remove the fan, having previously disconnected it from the power cable.
  5. Using a spray can treat all microcircuits more carefully.
  6. Wipe the cooler cell and plastic parts with a cotton swab moistened with distilled water.

Note: Never use alcohol! It very quickly destroys contacts and puts expensive parts out of order. Do not remove or wash the blades in the water.

  1. Lubricate the rotor with oil if desired. There is a distinctive hole in the cooler for this. It is quite easy to extract it. Place one drop of oil in the hole and twist the blades clockwise for a while to distribute it evenly.
  2. Dry and put the laptop back.

  Using A Spray Can Treat All Microcircuits More Carefully

It is better to carry out cleaning with the simultaneous replacement of thermal paste in a service center.

You may use a cotton swab slightly moistened with alcohol to clean the keyboard buttons. It will help prevent large amounts of dirt from getting inside the case.

Cleaning Tip: Software Can Help

Do not be surprised at what we have just said. You can clear up the mess inside the case without disassembling the laptop fans.

The essence of the method is that a specially downloaded utility accelerates the cooler to unimaginable speeds and knocks the dust off the fan in this way.

This method will help for not too dirty laptops. The program can not remove the layer of dust that has hardened from time to time.

Be careful not to download unknown programs from the worldwide network. We recommend using SpeedFan.

How Often Do You Need To Clean A Laptop Fan?

The laptop’s cooling fan helps protect against the power loss and the circuit of the circuit. After 2-3 years, the laptop may have dust inside the fan. If it’s not possible to clean a laptop fan, then don’t take it anymore.

Periodic self-cleaning of the cooler from dust is a precaution and can extend the processor’s operation several years. Besides, once every 15-20 months, you should take your laptop to a service center for more thorough cleaning inside the case.

Why Do You Need To Clean A Laptop Fan?

The fan in the laptop aims to cool all the main systems of the device during operation. It draws in cold air from the surrounding area, thereby reducing the temperature of the operating parts of the laptop.

The lack of a direct airflow can cause:

  • Melting and failure of the video card;
  • Overheating of the device processor;
  • Solder parts to each other;
  • The spontaneous shutdown of the laptop.

Replacing a microcircuit or any other part will always cost significantly more and more trouble than cleaning the fan of the device. If there is increased noise generation in the cooler, strong device heating during operation and constant shutdown, remove dust from laptop fans immediately.

  Accumulated Dust Prevents Your Laptop From Working Properly

Possible Problems After Cleaning

In some cases, due to inexperience or in a hurry, it is possible to assemble the device back incorrectly. The laptop may not turn on or crack at startup. Don’t panic!

Most likely, you have moved some parts during cleaning, and the fan blades are touching the wires. A few inches difference can be critical and affect laptop performance.

In this case, disassemble the laptop again and reassemble it carefully. The most important sign that you did everything right is the quiet operation of the laptop and more responsiveness to all user commands.


We have covered the simplest ways on how to clean laptop fan. As you can see, there is nothing difficult in cleaning the laptop fans from dust. You just have to do it on time.
