Cleaning Your Laptop Fan with a Hair Dryer?

Overheating laptops is annoying and can cause damage to the device’s CPU if they go too long without proper cooling. It might sound odd, but you can use your hair dryer to clean the dust that has accumulated inside the fan of your laptop or desktop computer, keeping it running smoothly and avoiding overheating.

Follow this simple guide to learn how to clean your laptop fans using only a hair dryer and not a screwdriver or any other tool, so you won’t have to worry about damaging your computer or voiding its warranty.

Can I use a hair dryer to clean a laptop fan?

Yes, you can. But not everyone will recommend it. The only reason why we can’t do it is that the hair dryer blows heat, so if you don’t know how to do it, you may damage your laptop. Because the air from a hair dryer is hot, you could damage the motherboard in your laptop if you get the hair dryer too close to the laptop. You should be careful and do it gently.

And there are so many other ways that are better than using a hair dryer to clean your laptop fan. For example, use a vacuum cleaner or compressed air. These methods are much more effective and they won’t damage your device at all.

However, if you want to clean your laptop fan with a hair dryer, make sure that you follow these steps: Turn off your computer and unplug it from the wall outlet and remove the laptop cover so you can get access to the fans.

Blowing the fan with the cover on can move the dust clog to a different place in the laptop where you can’t get blow it away so it’s advisable to remove the laptop cover to get access to the fan.

Put on some protective gear like glasses or goggles. Blow dust from the fans with the hair dryer but make sure the dryer is at least 10inches away from the laptop so you don’t heat up some of the components and damage the laptop.

Also, if you want to clean your laptop or computer fans, you can use rubbing, a paper towel, and a q-tip, just to be on the safer side.

Just put a small amount of rubbing alcohol on a paper towel and wipe down all of the fans inside your computer case. You should make sure that all fans are completely dry before powering up again.

Another way to clean out dust is by using compressed air cans. Many companies sell them at office supply stores, but they can also be purchased online as well. Just hold the nozzle a few inches away from each fan and let loose. When using compressed air cans, always wear safety glasses to protect your eyes from any flying debris.

Make sure you’re standing over a sink or outside when cleaning your computer fans. You don’t want those little hairs getting into places where they shouldn’t be.

The bottom line: Use an air compressor or canned air instead of a hair dryer to keep your laptop clean. Not only will it save you money (canned air costs about $3), but it won’t void your warranty like blowing warm air around would (your warranty is voided if you open up your computer though).

A little caution before cleaning your fan with a hairdryer

  • Make sure that your computer is completely switched off and unplugged. Use it at very low heat for about ten seconds and then switch it off quickly.

  • Now check if there are any wet patches on the inside of your machine or if there are any strange smells coming out of it.

  • If everything looks fine, then go ahead and start it up again. You should also check whether your machine has cooled down properly before switching it back on. If all goes well, then congratulations.

You can now pat yourself on your back for being both an eco-friendly and green user as well as an innovative do-it-yourselfer who came up with a cost-effective solution to cleaning his/her own hardware.

How often should you clean laptop fan?

Obviously, you should clean your computer’s internal components on a regular basis, but you may be surprised by how often most people need to have their fans cleaned.

The answer really depends on a variety of factors: where and how often you use your laptop, how dusty your environment is, what type of materials your keyboard and case are made out of (plastic or metal), etc.

If it’s been several months since you cleaned it last, then yes, it might be time for another cleaning. However, if you keep your computer in a relatively dust-free environment and use it daily, there’s no reason to worry about getting rid of excess dirt buildup. Just wipe down its exterior with a damp cloth every few weeks and call it good.

As you probably know, computers generate heat as they work, and that heat needs to escape so that everything doesn’t overheat. While some newer laptops feature sealed designs that limit cooling airflow (to improve battery life), most laptops still feature vents around their cases through which air flows in order to dissipate heat.

This is accomplished via a small fan attached to an internal heatsink, which pulls cool air into one side of the device and pushes hot air out of the other side. This process occurs continuously while your computer is running, when it works properly, you shouldn’t even notice anything going on inside your machine.

But what happens when things go wrong? Well, usually nothing too drastic, but sometimes overheating can cause system crashes or slowdowns due to excessive resource usage.

In addition, dirty fans can make a lot of noise and reduce overall performance. So, obviously, it’s important to make sure your computer stays cool.

How Do You Know When It’s Time To Clean Your Laptop Fan?

There are two ways to tell whether or not your fan needs cleaning: observation and temperature monitoring. In terms of observation, you want to check your laptop regularly for any signs of dirt buildup around its vent openings. If you see dust collecting around these areas, it’s time to open up your laptop and get rid of it.

Another thing to look out for is unusual noises coming from your computer when it’s under load. Fans tend to get louder as they collect more debris, so listen closely if you hear something new coming from your machine.

Finally, you can monitor your CPU temperatures using software like SpeedFan or CoreTemp. If your CPU gets too hot, try cleaning out your fan first before doing anything else, it could save you from calling in an expert.


Hair Dryers are great tools, they can be used to do many different things. However, I would not recommend using a hair dryer on your laptops because it will damage them and possibly void your warranty as well. The proper way of cleaning out your laptop’s heating element is with compressed air or by removing it and cleaning it with an anti-static brush.
