You might wonder why you should bother cleaning a dust-clogged laptop fan. After all, it’s already open. Well, it turns out that even though the fan is open, it’s still sealed from the outside environment. That means that dust particles can enter through the vents and accumulate inside the fan.

How Often Should a Laptop Fan Be Cleaned?

A quick blast every two weeks should be enough to keep a laptop cool and running at full speed if using compressed air. You can also blow out dust and debris with canned air.

Make sure to only take things apart from your dirty laptop if they’re absolutely necessary. This lessens the risk of damaging anything when you’re putting everything back together again.

What Are Some Common Indications That You Should Clean Your Laptop Fan?

When you notice your computer fan spinning at full speed and it’s still emitting excessive heat, there are a few possibilities why it’s not cooling down. Dust can get into the fan blades and slow them down.

Try turning off all unnecessary programs so they don’t take up too much processing power. Adjusting the brightness of laptop screens also helps in avoiding overworking them.

A laptop on bedding may also cause too much heat thereby overworking your fans. This will also affect the computer’s internal components so place your laptop on a cooling pad instead.

What Are the Advantages of Cleaning Your Laptop Fan?

The fan is a critical component of a computer because it is the cooling mechanism that prevents overheating. It pushes cool air over the internal parts of the computer, making sure that they are cool, and extending their lifespan.

Keeping your computer clean helps keep it cool for longer and avoids excessive heat buildup. This means that you can get the most out of your laptop’s capabilities.

Tech experts also say that regularly cleaning off the accumulated debris on the exhaust vents of your computer increases its fan cooling efficiency by up to 20%.


How Can I Determine Whether The Fan In My Laptop Is About To Die?

If the laptop is quiet and if you don’t feel any airflow, the fan might be damaged. If you can feel the fan working hard through the sound that it makes and you can only see gentle airflow coming out of the vents, then the fan could be blocked.

These are the common signs that your laptop’s fan is on its way to being damaged or is already broken.

Can I Activate The Laptop Fan Manually?

Here are the steps:

  1. Go to More power options > Change plan settings > Change Advanced power settings.
  2. Check for the System Cooling Policy option only if your laptop has built-in heat sensors.

Other steps may also be the following:

Search for the “Smart Fan” option on your computer and select it. You can then use choose to either disable or enable it. If disabled, the fan will run at full speed even without getting prompts from your computer.

Can I Clean My Laptop With A Hair Dryer?

Should you use a hair dryer, prepare for irreversible damage.

Can I Use A Vacuum To Clean The Fan On My Laptop?

There are some reviews that say hand-held vacuum cleaners can help remove dirt from your laptop fan.

Dust, dirt, or little bits of stuff you don’t want in your computer can collect in the air vents. Left alone, they’ll pile up and make your computer run hotter. That means it might shut itself off to prevent overheating.

Luckily, cleaning out those vents is easy, and only takes a couple of minutes.
