Dust is among the most common causes of laptop fan noise.

That’s because dust is often compressed into your fan by the action of spinning blades and then flung through the air, providing an excellent opportunity to accumulate in hard-to-reach places inside your computer.

As dust accumulation, it can block your laptop’s fan blades. This will make the fan work harder and make more noise.

To make sure that your laptop is always in perfect condition, try to clean the fan. You should do this at least once a year.

The good part is that you don’t need to purchase any fancy equipment.

You can use the screwdriver to remove your laptop’s case and prepare it for a thorough clean. 

To fix this problem you can follow these steps:

Firstly you have to switch off your laptop.

Flip the laptop to its backside and remove its battery. There, you will find the screws. Remove them and carefully lift off the cover from your laptop.

Look for dirt in different places: below space between keyboard and screen, around fans on top of the motherboard.

If any dirt is found there, clean it with a cloth.

It may be difficult to spot dust inside your CPU fan which can cause noise issues too, but fortunately, that’s even easier to fix than cleaning other parts of the laptop.

With the help of a small screwdriver just remove the back cooling panel from one side (right or left) and then use a compressed air sprayer to blow through all fan blades.

This way dust particles should get blown away so they won’t accumulate again after resuming operation.

Be careful not to open a laptop’s fan too much or you might damage the fins.

If your laptop is still noisy after this troubleshooting, then it may require a replacement, or it’s better You should take it to someone who knows how to fix this.

Elevate Your Laptop To fix Laptop's buzzing noise

You can fix a loud laptop fan by elevating it.

Place a book or something else under your laptop to elevate the bottom of the device.

This would allow air to circulate beneath it, reducing heat buildup in what is likely causing the laptop fan noise.

-The only problem with this fix is that you’ll need some sort of elevation each time you want to use your computer on different surfaces, such as an office desk versus a coffee table.”

You can also buy elevation tools that will fit on top of your laptop and allow it to be used at a variety of heights.

-One popular brand is Lap Desk, which has an adjustable height from about 15 inches to 27 inches high.”

Even if you don’t have any noisy fans, consider buying an elevation tool to prevent it in the future.

If you hear some grinding noises coming from the fans, it could be because of a buildup of dust. You will also notice the fan emitting hot air. A quick fix to this problem is getting an additional cooler for your laptop and placing it below the one currently in use.

Laptop coolers counter the hot air coming out of the loud laptop fan. You would notice a decrease in noise.

The laptop cooler must be placed under the fan. You will see a grill at the bottom of the laptop. The opening on this grill is where you want to place your standalone laptop cooler.

Now your computer should work better because you have fans that are working. People with laptops should get coolers for their computers to protect them in the future.

 6. Replace the Thermal Paste 

Fixing noisy laptop fan: Replace the Thermal Paste

One of the most common fixes for noisy laptop fans is changing out the thermal paste.

Simply put, thermal paste fills in all those little crevices that are not filled by your CPU and heatsink.

Its job is to help conduct heat more evenly from one component to another as well as fill up any gaps so you can have a better transfer rate between them.

If it dries out or deteriorates over time then it will cause an increase in noise due to less contact with both components.

This means they aren’t transferring heat efficiently which could be heating up other parts on your computers like the motherboard and RAM modules too!

This quick fix may save you some money down the line if your computer is already loud.

if you have never done this before, it’s about as easy as using toothpaste.

The only “tricky” part is ensuring you have the right amount of thermal paste on hand for a new installation.

If you’re still having problems, then your next move may be to get a professional to do it for you.. 

Other Multiple Methods to fix noisy laptop fans 

To keep your laptop running optimally, there are many ways to fix a noisy fan.

There is no reason you can’t do all of the things listed to fix a noisy laptop fan.

An easy way would be closing all programs that may contribute to the noise and elevating it so air can circulate better.

Getting malware is also an option for optimum maintenance of the machine which will prevent future problems down the line.

In general, keep your machine running well now and in the future, you have to perform each and every method.

if non of the above fix helps you then the replacement fan would be a good choice, but most laptops can be fixed through these hacks, if you have an old laptop then you can go for a replacement of the fan.

Fix Hard Drive Failure 

If none of the above fixes work for you then it means the noise is coming from the hard drive, or it could be a sign of hard drive failure.

if this is the case then it’s important to back up all data immediately and replace the hard drive.

The grinding, whirring, and clicking sounds could sign of the hard drive on its last legs, so it’s important to act fast.

You should never delay a possible hardware replacement if you are hearing these kinds of noises and have no other fixes available.

Final thoughts

Noisy laptop fan is a common issue for many computer users. There are several steps you can take to fix this problem.

The first thing is to let your machine sit on a flat hard surface and not keep it in the same position all day long.

Then clean the internal components with compressed air or an appropriate vacuum cleaner attachment if necessary.

You should also allow any running processes to finish before turning off your computer by using CTRL+ALT+DEL.

These can be causing background noise that will remain when you turn off the device.

Lastly, always run reliable antivirus software so that you don’t have malware slowing down your laptop while simultaneously creating more sounds from inside of it.
