How To Clean Laptop Fan? Tips New 2022

One of the most important – yet often overlooked – components of a laptop is its fan. Over time, dust and dirt can accumulate on the fan, causing it to work less efficiently and eventually leading to overheating. In this article, we will show you how to clean laptop fan in a few simple steps.

Laptop fans can become clogged with dust and debris, which can cause the fan to overheat and eventually fail. Cleaning the laptop fan is a simple process that can be done with a few household items.

There are a few ways to clean a laptop fan. The most common is to use a compressed air canister. Another way is to use a vacuum cleaner with the hose attachment

What Makes a Laptop Fan Dusty?

Dust is a common problem with laptop fans. They inhale all the dirt from the air, resulting in a construct of gunk – gross.

While you may believe that just a little dirt won’t hurt, accumulated dust throughout laptop fans could indeed prevent proper airflow, resulting in overheating and the potential for your CPU as well as GPU to be cooked.

1. If You Can Open Your Laptop

The majority of laptops, particularly newer models, are not designed to be kept open by one’s users. This is a significant issue. On a desktop PC, you’d turn it off, open the case, blow it out with compressed air, and then close it. A laptop could be dusted in the same way if there was only a way of opening it up and getting into it.

You may be able to access these same internals of your laptop by unscrewing a bottom panel (or several bottom panels). Confirm your laptop’s handbook or go online to find a special “service manual” for your laptop prototype. Turn it off, change the battery, and disassemble the panel to access the laptop’s inner workings.

What Makes a Laptop Fan Dusty?

After it’s opened, move the laptop to a location where it won’t become dusty, such as your garage or outside. Blow out the insides of your computer using compressed air from a can. Make careful to blow the dust out of the laptop’s casing rather than merely pushing it about within.

You may, for example, direct more of the blow at your laptop’s vents, causing dust to be blown through the vents and out of the computer. When pushing air just at fans inside the laptop, take care not to harm them by spinning them too fast. Blow brief bursts of philosophy at the fans from a variety of angles.

There’s a reason we advocate compressed air, often known as canned air. Utilize an air compressor instead of a compressed air can if you don’t want to use suction, and be extremely careful when you do.

Replace the panel, connect to the battery, and turn on the laptop when you’re finished. It will run more relaxed, and its fans will turn on less frequently.

2. If You Can’t Open Your Laptop

You can still try to get rid of some dust, even if your laptop isn’t accessible. Take the laptop to a place where you aren’t afraid of getting dusty. Dust is not something you want on your desk or bed.

A can of compressed air is all you need to get the cooling vents of your laptop working properly. Could you give them a few quick blasts of air? The atmosphere should knock some dust off the laptop’s vents. Although you won’t remove all of the dust from the computer, it will at least stop it from plugging up any fans or vents. Although this is not the best way to dust a laptop, it might be all you have.

This is a dangerous practice. You could cause the cooling fan’s speed to increase if you direct compressed air at it. Do not aim your compressed air at the fan with a prolonged blast. To avoid spinning the fan too fast, you should blow air in short bursts.

If your laptop is experiencing severe heart problems and you cannot fix it yourself, the manufacturer may help you. They should help you if your computer is still under warranty.
