how to fix a noisy laptop fan

It’s getting on your nerves again! You are just typing on your laptop, but its fan is too noisy once again. How many times a day does laptop fan noise bug you?​


Sometimes, it takes you by surprise when it just suddenly goes super loud unexpectedly because it is as if there is a bomb in there. If you have asked yourself many times ‘why is my laptop fan so loud’ or if someone has asked you ‘why is your laptop fan loud’, this post is certainly a perfect one for you.

Why Is My Laptop Fan So Loud?

An unbearably loud laptop fan is a sign that your laptop is always hot. A fan will always spin faster and more often when there is more heat to disperse.


There are many reasons why your laptop is becoming this way. In most cases they are easy to solve and will not take a lot of effort for you to deal with. Here under are some issues that may be causing the noise. There are several culprits to consider.

Age of the Laptop

Sometimes, your laptop will get too loud because of its age. The older a laptop is, the more susceptible it is to becoming too loud.


The reason is some parts within the computer itself become loose and worn out. You may have to seek professional help to determine what needs changing or just buy a new laptop all together if it is already too old.

Build Up of Dust and Hair

Dust and hair, yes your hair, can get sucked into the fan vents. When there is a lot of those built up into your unit, then air flow is reduced.


The consequence of this is poor heat dissipation, which means your laptop fan is working extra hard, and therefore, a lot more noisy.

Presence of Malware

Another reason your laptop is too loud could be Malware. The presence of this disruptive component has been a known culprit for making your machine too noisy because it is running several programs behind the scenes.

Processes, Tabs, and Programs Not in Use

This is often true for many people. They leave processes, tabs, and programs running in the background. If these aren’t properly closed, they can still affect your computer’s efficiency and productivity, which will eventually cause your laptop to work more and create more heat causing the laptop fan to work harder as well.

Laptop Fan Loud Effects

Never underestimate the effects of a loud laptop fan. If your laptop fan is too loud, the primary concern is that your laptop is overheating. An overheated laptop means that its processor slows down and operates with much lesser efficiency.


This is a generally an issue, when it comes to bigger gaming laptops.


The motherboard of your laptop can also be affected. This is the skeleton framework for your PC because all of the laptop’s important components like the processor, memory, fans, and wiring are all interconnected to the motherboard. If your laptop is prone to overheating, which is seen in the loud fan noise, then you could end up frying the motherboard.


On top of that, a laptop that is frequently hot can harm the lithium ion battery that comes built-in with the computer. The added heat increases the chemical reaction within the components of the battery, which reduces its life and the amount of time it stays charged. Prolonged exposure to heat makes your battery unstable, which could also damage your laptop in the long run.

How to Fix Laptop Fan Noise

Before you consider giving up on your laptop, there are some quick fixes that you can do to reduce the noise level. You can also use these same strategies to ensure that your newer laptop will not succumb to the same problems. After all, prevention is better than cure.


Check out the details below because these are the most effective ways of dealing with laptop fan issues.

Get Rid of Dust, Hair, and Other Debris

Since the most common culprit of a noisy laptop is dust, hair, and other debris, you may have to end up opening the machine to get to clean the cooler. Typically, dust, hair, and debris accumulated over time will cause the fan blades to not work properly, hence the increased noise.


There should be a routine cleaning of its cooler, twice a year would be most ideal, so you can blow out the dust, hair, and other particles that get stuck onto the fan so that it will continue to work properly. If you are frightened to do this yourself, leave it to the professional. If your laptop is under warranty, don’t do this on your own as it can void the warranty.


If you are pretty daring, you can this yourself because all you really need is a screwdriver. Make sure the laptop is off and unplugged. Flip it on its backside and take out the batteries. Find the air vent and unscrew the panel. You will see that fan underneath and begin blowing dust out of it.


If you see hair and other debris, then gently take them out. This will result in a quieter laptop fan and a faster working laptop.


While you are at it, make sure to clean your laptops' keyboard as well.

Search and Destroy Malware

Malware is deadly for any laptop, especially if you don’t have any anti-virus.


Malware is a culprit for slowing down your computer and raise its temperature because it is not performing properly. This will result in your laptop being a lot louder while performing even simple procedures.


Since most of the viruses are working incognito, it will be impossible for you to notice them without an anti-virus. If you don’t have an anti-virus program, it is time to get one for your laptop. There is no excuse not to have one installed because there are many free ones online, with possible premium upgrades for better protection.


Once you deal with the viruses, your laptop will be able to run applications and processes a lot easier. It will reduce your laptop’s effort, which equates to less heat.


Along with all of this, there will also be a reduction in noise.

Close Processes, Tabs, and Programs

Leaving all of this open and silently waiting in the background takes up or eats a certain portion of your laptop’s processor and ram memory. Even if you’re not tinkering with them, they keep your laptop’s main parts occupied, making your laptop work a lot harder than it should.


A lot of open processes, tabs, and programs will lead to some unwanted overheating, which will make your fan go on overdrive. If you want to reduce the noise, go to your task manager and kill those operations that you have neglected to close.


You can also set up your PC in such a way that opening Chrome or Safari will not open a new process for every single tab. It is possible to fix the browser setting to create only a single process for multiple tabs browsing the same site. This saves your laptop from unwanted load.

Use an Added Cooler

To cool your laptop a lot faster and much better, you can opt to add an additional cooler, which has been created specifically for this purpose. This will certainly work wonders in preventing your laptop form overheating. It will also stop your laptop fans from making too much noise.


This is fairly easy to do and you will just usually have to place this underneath your laptop to get things to work. With the addition of these cooling fans, your laptop performance will improve drastically for the better.

This additional laptop cooler is an absolute must-have for those who work with highly complex processes on their machines.

Think of a Software Solution

Majority of the laptops produced these days will allow you to control the fan speed with a third-party software.


This way, you can monitor the speed of the fan at various times, so you won’t be caught off guard by the loud noises. You can choose to increase the speed of the fan during those moments when you will be working heavily on your PC.


Aside from fan data, these apps can also help you gain insight on your laptop’s other internal data, so it’s not bad at all. Windows users can consider SpeedFan, while Mac users can try smcFanControl.

Literally Lift your Laptop

Simply elevating the laptop from the surface will help with your issues. The cooling fans are in the bottom, so if they are already on overdrive, it is best to leave a bit of space underneath your laptop. You can prop it up with a book to create a gap, so that fan can blow a lot more cool air into your laptop. This will reduce the noise and heat immediately.

Bottom Line

The aforementioned details are quick fixes and also preventive measures to ensure that your laptop remains in good condition.


If you’ve done everything you possibly can to mitigate the noise and it is still not working properly, a trip to a professional may be in order.


However, before you decide on replacement parts, calculate all the costs including labor, downtime, and spare parts before paying for anything. You might be surprised that it would be a lot cheaper to just get a new laptop if the damage in your PC is too severe.


If all fails, and your laptop is unbearably loud, invest in a new one.
