After you’ve gone through these methods to fix your laptop, you should end up with a quiet and sound system. 

Why is my laptop fan so loud?

Dust and Dirt Build Up

One of the most common causes of a noisy laptop fan is dust. This causes damage to your laptop in diverse ways. Some include; obstruction to the laptop fans leading to loud noises, and also affecting vital hardware.

The processor of your laptop is a major part so it is advisable to clean your system frequently to also dust build up in those areas. With time debris and dust accumulate around the cooling system.

This can be a hindrance to airflow, can also cause laptop overheating and abnormal fan operation.

Also, laptop making grinding noise can be a result of dust close to the CPU fan, which will cause the fan to be less effective.

Software Issues

Fan noise can also be triggered by issues related to software problems.

Microsoft can bring out an update that may not be optimized and can cause issues in your system. This will increase the speed of your fan as your computer tries to keep the temperature under control, and this can make your laptop fan loud but not hot. 

Clogged Air Vents

The loud noise generated by your new laptop fan can also be a result of the failure of your computer to run efficiently and clogged air vents. The air vent can be blocked by anything. 

Accumulation of dust around and on the fan blades will lead to the laptop making a buzzing sound and freezes. Use a damp rag to remove debris and dust on the fan blades.

Also, if there is an obstruction to the fan, the blades might be hitting that obstruction, thereby causing the noise. 

Faulty Cooling Fans

At some point, your cooling fans may become weak and significantly reduce ineffectiveness. As you continue to use them, they begin to wear out, until they eventually die out.

You won’t be able to run your laptop on a bad fan, so if your laptop fan is damaged, it has to be replaced. 

If you are familiar with computer repairs, taking the faulty fans out wouldn’t be so difficult.

But remember that the moment you perform personal repairs on your computer, the warranty is void. It’s only valid when the repair is carried out by a certified professional. 

10 ways to Fix Laptop Fan Noise

1. Change Your System’s Settings

When there are no intensive tasks or games running in a new laptop system, and your fan still sounds loud, then the problem is from the system.

Thoroughly inspect your CPU usage. After a proper check and you can’t find any fault, you have to change your system’s settings to reduce the noise.

On a Windows 10 system, go to START. Click on Settings, and then to System. After that, move to Power & Sleep, and open Additional Power Settings. Click on Change Plan Settings. Locate the Change Advanced Power Settings and click on it. Press the Processor Power Management, and click on System Cooling Policy in the Menu. Select Passive; change the System Cooling Policy from Active to Passive. Then click on the OK option. 

2. Clean The Fans

When your fan sounds abnormal or produces loud noise, and you have a reduced air volume, then your fan has too much dust settled on it or it can also be due to inhalation of sundries, which can lead to a very low heat dissipation fan efficiency.

Most especially when you’ve never cleaned your laptop system before. 

To fix this situation, you have to remove the built-up dust from your fans and heat sink.

If you don’t know how to wipe off the dust on your own, it’s best you take It to the nearest repair shop for proper maintenance. 

The wrong cleaning approach can damage other components, and you don’t want to add other problems to the list.

Once your laptop fans have been well cleaned, the sound produced from the fans should now be very low.

3. Replace Your Cooling Fans

If your laptop is more than four years old, then cleaning might not be sufficient enough to stop the noise as the heat dissipation efficiency is not good enough for the system to function as it should.

We won’t advise cleaning as the only solution to a loud fan above three years old. In this case, you might have to change your laptop’s cooling fans.

Do not try replacing your laptop fans on your own, if you do not have the necessary know-how.

We always suggest that persons in this category should go to the repair shop for the right repair.

But if you own an ultrabook then replacing or cleaning your cooling fan shouldn’t be an issue. You just have to take off the cover at the back, and once you’ve gotten that out, the rest should be easy. 

When replacing the laptop fan, apply thermal grease to avoid complications on your GPU and CPU.

Still, if you do not understand this procedure it is better to take your laptop to the repair shop than risk destroying the fan altogether.

4. Create More Room For Your Laptop To Cool Down

Most persons use their laptops without thinking of the amount of heat dissipation and airflow in the system until they keep the laptop on their laps.

The air vents of most laptops are under the system, so your laptop will definitely get hotter whenever you put it on your laps, and that is because your laps are blocking the fan vents. 

By placing your laptop on your laps, the heat generated within the system will not be able to be transferred out, leading to heat buildup and that can increase your fan noise due to overworking. It might even damage your fans. 

A quick solution is to avoid placing your laptop surfaces that won’t provide their base room for airflow.

You can opt-in for laptop stands, check our article on the best laptop stands to get the right one for your needs.

When your laptop base has enough room for airflow, your fan won’t have to work extra hard and it will prevent your system from overheating.

5. Get Rid Of Viruses And Malware

Viruses and Malwares are usual disturbances that can cause complications in your laptop. Although Macbooks are highly immune to these types of afflictions, you might still experience malware infections. 

If you can’t spot out the reason for the loud fan noise from your computer, then it is most likely a virus or malware problem.

This problem can stop your system from functioning effectively.

It can cause your laptop to begin running irrelevant processes continuously, and this can increase your laptop temperature, which will in turn increase the fan speed level. 

The most appropriate way of handling viruses and malware from occurring now, or in the future is to equip your laptop with good antivirus software.

There is free and effective antivirus software that will diagnose your system after scanning, and also remove a certain amount of the viruses.

You might have to pay for the unlimited version to get the whole thing out of your system, but it’s worth it.

6. Clean Your Air Vents

Unclogging your air vents is a good place to begin fixing fan noise issues in your laptop.

Plus, it is so easy, cheap and it is most times the reason why laptops begin to produce so much noise.

A laptop system has two vents, one of the vents is to allow inflow of cool air, while another one is to allow hot air escape. 

If any of these vents gets clogged, then your fan will have to work extra.

You can easily spot your vents by looking around the base of your laptop. If you notice the accumulation of dust in those areas, then you have a problem. 

You must wipe off the vent holes with a towel or cloth, or you can use a dust removal spray to get rid of them.

Also, inspect the surface your laptop rests on, it’s also possible that the fan vents are blocked. Avoid putting laptops on soft surfaces.

7. Get A Laptop Cooling Pad

Although this might be an expensive option, you also have to consider the fact that it is very effective.

Overheating is a common problem with laptop systems, typically with modern systems, so manufacturers use the coolers to make up for the insufficient in-built cooling fan. 

The laptop coolers ensure your laptop gets a constant and sufficient airflow running into the system, rapidly cooling your internal components.

This also means far less work for your in-built fans, so they don’t have to work that much. 

Be careful, there are a lot of laptop cooling pads in the market.

It’s important you get the perfect one for your system, and to get that you have to check our guide on the best laptop cooling pads to select from the best coolers out there.

8. End All Irrelevant Processes

You can open your Task Manager, and see just how many background processes are running in the background. You might not be able to determine what most of them are being used for.

However, some processes are essential to keep your system functional, do not tamper with those. But there are others that are so unnecessary, and while they are on, your battery power goes down the drain. 

Too many processes give your system a higher workload, and that spikes up to its temperature, causing your fans to run faster and louder.

You can close those irrelevant processes through your Task Manager.

Unnecessary processes can be related to internet browsers, games, and video and music players.

Ending these processes will relieve your system of a significant amount of workload, and this will also reduce the stress on your fan.

You should now have a quieter fan operation. 

9. Swap Your Old Laptop For A New One

It’s no secret that modern laptops run on better and newer technology, and also operate quieter than old laptops.

You can try using several processes or methods to make your old laptop run quietly, but it can never be as quiet as a new modern laptop.

If you’ve used your laptop for more than a four-year period of time, and it produces so much noise now, then it’s time you swap it for a newer system.

You can head down to your computer or electronic store to check out some new laptops, and see how they sound. You will be amazed at how low the fan noise is. 

Changing your old laptop for a new one can be a high investment, it’s best you explore other options to get your fan noise down before going ahead to replace the laptop.
