How to Clean A Laptop Fan? – 4 Easy Methods

Laptop fans remove heat from sensitive parts on the motherboard, such as the CPU. They are, however, prone to get clogged with dust and debris from the atmosphere when they suck air in. This will result in overheating. Keep reading to learn how to clean a laptop fan.

Dust and soil fragments can be blown away from the fan assembly with a can of compressed air. A portable dust blower with relatively low pressure can also be used to produce the same results. If you don’t have any of these things, a soft fabric, cotton balls, or cotton swabs may be used to clean them.

Of course, the amount of debris on the fan will make the cleaning process more difficult. To enter deeply entrenched dirt and soil, a complete fan disassembly may be needed in some cases.

How to Clean A Laptop Fan?

To clean the fan thoroughly, you’ll need to open up the laptop. A basic Philips head screwdriver can be used to loosen several of the screws.

Others have a single body. The bottom cover must be carefully removed from the chassis at this stage.

A clean work surface is important, and a method for arranging the screws you extract is also helpful.

Remove the fan from its mount when the laptop is open to clean it separately from the rest of the components. To do that, unscrew it and then unplug the cord from the motherboard.

Following the disassembly, there are four different methods to clean a laptop fan:

  1. Compressed Air / Air Blower
  2. Laptop Cleaning Brush Kit
  3. Soft Cloth / Cotton Balls
  4. Rubbing Alcohol

Compressed air in a can is ideal for electronic use. No moisture will damage the electrical components because it’s dry air. Furthermore, the strain is closely regulated to avoid damage to your system.

You will point the nozzle of compressed air at the part of the fan you want to vacuum. Short blasts of air can then be used and attempt and dislodge the dust and dirt from the fan.

With a hand-held dust blower, you will get the same results. Use just the ones designed for cleaning delicate electrical components.

Advantages

Compressed air is more suitable for difficult-to-reach areas. Furthermore, since it is under heat, it is suitable for dislodging even larger dust clumps and delivering a more detailed clean without causing the fan to be disassembled.

You can save compressed air cans and use them again the next time you decide to clean your fan. When they run out, many hardware shops sell them at a fair price.

Caution

It’s important to understand how to clean a laptop fan properly with compressed air. Since they use so much air pressure, some dust blowers are not suitable for fragile electrical components. As a result, using them on your laptop fan can result in injury.

It’s also worth noting that compressed air can often worsen the problem by catching dust particles in the fan. As a consequence, it’s important to double-check the fan to make sure it’s as clean as you require.

There are different sizes and types of brushes available for cleaning different parts of the PC. Using brushes is an excellent alternative to compressed air. In order to clean the laptop fan with brushes, you have to first choose the right brush.

Since a fan is not as delicate as a motherboard or other electronic circuits, you can use slightly harder brushes.

Make sure you clean the rim as well as each blade. If the cable connector has accumulated dust, make sure to clean that as well.

Advantages

If you do not have a compressed air can or an air blower lying around, then you can employ this method. You can even use a spare toothbrush, however, if the toothbrush has hard fibers, then make sure you are very gentle with the cleaning processor.

Caution

Using a brush that is too rough will cause the electronics to be affected. Cleaning the fan blades and rims should not be a problem, but when cleaning fragile electronics with a brush, make sure to use a gentle one and apply very light pressure.

Without the use of compressed air, here’s how to clean a laptop fan. You’ll need a soft, clean cloth for this. You may also use cotton balls or cotton swabs, but be careful not to leave any fabric fibers behind.

When ready, rub the dust off the fan, making sure to reach all the surfaces. This means that even the surface under the blade needs to be accounted for.

Cotton swabs are used in this phase. You can fit them between the fan blades or around it to get to the hard-to-reach areas if they’re small enough. Any portions of the fan can need to be disassembled.

Advantages

This system makes use of items you may already have on hand. As a result, it is much less expensive in the long term, because you can handle it yourself.

Caution

When wiping down the fan blades, softly keeping them down to prevent them from spinning on their axis. This should make the job a little easier.

It is important that you should not use undue force when doing so, since you do not want to harm the fan unintentionally. Too much strain on such a fragile part can be catastrophic.

4. Clean A Laptop Fan Using Rubbing Alcohol

Sale
91% Isopropyl Alcohol 32 fl oz Bottle (2 Bottles)

When you have caked dirt on your laptop fan, rubbing alcohol like isopropyl (IPA) will help. To remove dirt, dab a little alcohol on a clean piece of cloth and gently rub the area.

It is recommended that you use the purest form of isopropyl on your electrical parts, and you should have no difficulty doing so if the purity is 90 percent or better, as it vaporizes easily after application.

It can also be used on electrical parts because if the fan’s controller board is dirty, you can use it to clean it.

Advantages

IPA evaporates fast and leaves no residues. As such, it’s great for electrical components. It can be used to remove anything from dust to greasy smudges on the fan.

Caution

First and foremost, make sure that all of the isopropyl has dried up before reinstalling the fan. It’s also worth noting that the alcohol, as well as the vapors, are flammable, so keep the gadget turned off and away from any open flames while using it.

Although IPA can be used on metallic parts of the fan assembly, it can cause unintended reactions on certain plastics, so don’t use too many on the plastic fan blades.

How To Clean A Laptop Fan Without Compressed Air

If you don’t have access to an air compressor or a can of compressed air, you can use a soft cloth and rubbing alcohol instead.

To use the rubbing alcohol, you must first clean the rigid and bulky dust from the fans. Compressed air can assist with dust removal, but you can also use a soft brush to softly clean the fan before using rubbing alcohol or a soft cloth to properly clean it.

Final Thoughts

Knowing how to clean a laptop fan is a great ability to have if you want to keep your machine running smoothly.

This can be done with a can of compressed air. You should also go to the manual road and brush the dirt away with a warm dry rag. If necessary, rubbing alcohol (isopropyl) may be applied to the piece of fabric to remove stubborn stains.

Be gentle when cleaning the fan, and make sure to separate it from the rest of the motherboard to make your job simpler. The laptop should also be turned off during the operation.
