In this article, we will discuss the top techniques to fix a loud laptop fan.

Why Does the Laptop Fan Make Noise?

Laptop Fan Make Noise

The fan is the loudest component in a laptop. It spins continuously to cool the laptop system. When the system overheats, the fan turns faster hence making more noise.

Normally, some laptops are louder compared to others. However, if your computer noise suddenly increases, then there could be a problem with your laptop. Changes in hardware or software could cause the noise change.

The following are common reasons why your fan will make more noise.


When your laptop overheats, it’s cooled down by the fan. Therefore, the fan spins very fast to circulate fresh air from outside. The air is circulated through the laptop system and carries the heat away.

This process makes more noise in the fan as compared to when the fan is functioning normally. When the laptop has overheated, it spins very fast to supply more air to the laptop.

Dirty Fans

The fan is inside the laptop. Time over time, dust and other debris get stuck on the fan. Most of this dirt is sucked together with the air to cool down the laptop.

Dirt on the fan makes it heavy. It becomes difficult for the fan to spin with ease. The fan efficiency is also reduced. As a result, the laptop begins overheating. When the laptop overheats, the fan spins with a loud noise.

Blocked Vents

Laptops vents are for letting air in and out. There are two vents on the laptop. The inlet and outlet vents. Inlet vent brings in the fresh air inside your laptop. On the other end, the outlet vent takes heated air from the laptop. When one of these vents are blocked, the fan makes a lot of noise.

laptop Blocked Vents

For example, when the inlet vent is closed, the fan will strain to have enough air in the laptop. As a result, it will make more noise. On the other end, the fan will strain to remove hot air when the outlet vent is closed. When the fan can’t extract or supply enough air into the laptop, the whole system shuts down.

Therefore, avoid using your laptop on soft surfaces or laps. This will reduce the airflow hence trigger your fan to spin faster than normal.

Hard Drive Failure

Sometimes the noise in your laptop could come from the hard drive. If you notice the noise coming from your laptop is in the area near the drive back up your data quickly. This could be clicking, grinding, or whirring sound.

The noise is as a result of mechanical components inside the hard disk. As a result, the hard drive becomes noisier. The solution to this problem is to remove the hard drive and replace it with a new model disk.

When the hard drive fails, it also strains other laptop components like the fan hence making more noise.

Damaged Laptop Fan

Damaged Laptop Fan

If your fan is making some screeching or funny noise, then it could be defective. The fan could have been broken or not installed correctly.

This could have happened when someone tried to clean the fan. You could have damaged the fan if you used a dust blower to clean the fan.

A broken fan will make more noise. Also, the loose fan will make excess noise since it’s not well fixed in your laptop.

Strained Resources

Every laptop has its capacity. If you run your computer beyond its ability, it will start overheating. For example, if your laptop has a low processor and memory, some programs cannot run through it.

If you try running these programs, your laptop becomes slow and overheats. The program overworks the memory and the processor. They, in turn, strain the whole system. Hence, overheating your machine. As a result, the strain triggers the fan to run fast to cool down the laptop.

Heavy Software’s Running at the Background

Sometimes everything can be okay with your laptop. A clean fan, unblocked vents, and everything else perfect. But at the same time, you may hear laptop noises. If this is happening to your laptop, worry not.

There could be some software’s installed on your computer that keeps running.

Some of these software’s could be malware. Computer malware runs in a computer without authorisation. Therefore, your laptop will be working even though you don’t see any operation.

Quick and Easy Ways to Fix the Laptop Fan Noise

The following are techniques to fix with laptop fan noise;

1. Unblock the Vents

Check your inlet and outlet vents. In most laptops’ inlet vents are located beneath the laptop. The outlet vents usually are on the sides. Check if either of the vents is blocked.

Remove anything that is blocking the vent. If you have placed the laptop on soft material like cloth or coach, lift it. Place it on a hard surface. Your laps will also block the vents.

If after placing the laptop on a solid surface still makes some noise go ahead and raise it. Probably the rubber pads underneath your laptop are worn out. If they are worn it out, mean the hard surface can block the vents too.

Ensure nothing blocks air from getting or out of your laptop.

2. Clean the Fan

Clean the laptop Fan

If your fan is making more noise than is supposed to be making, it could be dirt. The first option is to clean it.

The best way to clean the fan is to open the laptop. Pull the fan outside. Then use a soft material to wipe all dust and debris on the fan. This technique will remove all the dust and dirt stuck on the laptop fan.

However, do not try this if you don’t have experience in servicing laptops. Alternatively, get a professional technician to clean it for you. Cleaning laptop won’t cost much. If you try to open it yourself, you might damage your entire laptop.

Also, if you use your laptop for a very long time, get cooler. As you work, your fun will start getting slower hence triggering the noise.

Laptop Cooler pad

The laptop coolers suck the hot air before your fan starts making noise.

There are two types of coolers; baseplates and clip coolers. Baseplates are most common. You just place your laptop on top of them, just like you put the laptop on a desk. The clip cooler, on the other end, it’s clipped directly to the outlet vents to suck the hot air out.

Therefore, if your laptop is noisy, or work for long hours, get cooler. Buy one on Amazon and say goodbye to laptop noises.

Therefore, go ahead and fix all the software issues. Ensure you only install programs that can be supported by your laptop. Also, remember to close all applications that are not in use.

8. Combine Different Techniques
