How To Fix Loud Laptop Fan Noise | 8 Ways To Approach

How To Fix Loud Laptop Fan Noise

Quiet environments are the most preferable for work.

We’ve all been to those days when our laptop irritates us through the noise coming from its fans.

So I was using an Asus laptop from 1 year & its fans used to make a lot of noise. I used to get very frustrated with it which resulted in losing my focus.

I wasn’t willing to buy a new laptop back then, so I thought of fixing the problem myself.

Here I’ll discuss the things that I implemented to fix the loud laptop’s fan noise quickly.

I’ll make sure to explain everything in layman terms so that anyone can easily apply these to their laptop.

Recently I bought a new laptop from Lenovo as I wasn’t convinced with the performance of the previous laptop and the loud noise was just painful to the ears.

Clean your laptop & eliminate the dust

We are starting things with the very basics.

We know dust is everywhere. No matter how clean your surroundings are, dust travels through the air. So, if you have a window or some opening, then the chances are that you’ll encounter dust in some or the other way.

Now all laptops have vents at the bottom from where they pass the heat.

All the dust can quickly enter there which can partially choke out your fans.

The solution to this is straightforward.

You can use an air blower and try to blow all the dust present inside of fans. However, blowing from outside won’t take out all of the dirt. If you want to make it perfectly clean, then you need to open the laptop from behind.

Back of the laptop can be opened with the help of a screwdriver. After opening, clean all the dust with the help of a brush.

Use a thin brush to easily clean the fans from inside as thick brush would make the task much more difficult.

After cleaning the fans and inside of the laptop thoroughly, place all the things back to their place. Do this task in a closed room and with concentration as a little mistake can mess up with your laptop.

You would immediately feel the effects of it after cleaning. It would make the fans comparatively much quieter.

It’s easy to implement, and the results are good as well. It worked for me so it would work for you as well.

Control your fan with software

It’s not always necessary to play with the hardware of your laptop to make it quiet; Software too can give very significant results.
Sometimes even better than the hardware.

Now, this step is dependant on whether your laptop company allows you to take control of the fans.

However, this can be done quickly with the help of solutions like SpeedFan. It allows you to control the speed of your fans and troubleshoot all the problems soon with it.

A lot of laptops tends to make a lot of sounds even when they’re sitting idle. Here you can install applications like this and lower the speed of the fan as it is entirely unnecessary. It can also give you a little boost in the battery life while making the sound coming from the fans much less.

In my testing, this turned out to be the best way to reduce the noise of the fans. It allows the user to get all the access to them so we can choose the fan speed according to our needs.

I won’t recommend reducing the fan speed while you’re doing some power consuming. It usually results in less efficiency and more thermal throttling.

It’s a must-use solution from my side to fix the noise problem of fans. Just be aware of when & how to use.

Change coolant or add an extra fan

The number one reason behind the fan running faster, which eventually makes all the noise is thermal throttling.

Heat triggers both the laptop’s software and hardware and makes the fan run faster to make the temperature go down. In the process, a lot of energy is used, creating noise as a byproduct.

An easy fix to this is replacing the coolant of your laptop’s processor.

With time the conduction power of the coolant fades away, so it’s much better to replace it with a fresh one every 6-7 months.

We may think of it as a small thing, but it makes a big difference.

Another thing that you can add is an extra fan at the bottom.

It would help the heat to dissipate much faster, which would signal the fans to run at a slower speed.

If you want to fix your fan’s noise problem to perfection, then you should take this action.

It is a cheap DIY fix as you can easily get a coolant for somewhere around 10$ from Amazon and it’s not even time-consuming as well, Implement this when you open your laptop’s back to clean the fans.

It’s a win-win situation for you.

Uninstall Malware & unnecessary applications

A lot of times we install applications that we actually don’t need and later on forget to remove them from our system.

Applications that tend to run in the background consume memory and power, and if you’re very careless with these things, then the chances are that you have a lot of malware installed.

The worst part is you don’t even know about them.

The quickest solution is to go to your installed applications list and remove all the apps that are unnecessary that you don’t use.

Also, go to the task manager > startup section in your Windows and disable all the high impacting apps on startup.

Disable Startup Apps

It is a crucial step as when these type of power-consuming apps run in the background, and the processor has to do more work, including the typical tasks that you perform.

These apps make the temperature of your laptop go up, thus, increasing the speed of your fans which later on makes noise.

The solution is pretty simple, but the fruits are delightful.

For MAC – Reset SMC & PRAM

Most of the software fixes above were for Windows users.

If you’re a MAC user and you’re facing problems with fan noise, then an easy fix for you is to reset your SMC & PRAM.

SMC is a system management controller which controls a bunch of hardware including cooling fans in Intel-based Macs.

Resetting it could instantly fix the noise problem as it’s the main component organizing the fan’s hardware.

Another solution is the PRAM.

PRAM consists of the configuration of your apple device. New generations devices come with NVRAM while older one uses PRAM.

Anyways it’s the same thing.

If you figured out that the problem with your fans is software related then resetting PRAM would fix the problem for the most part.

Here are the steps to reset the PRAM/NVRAM on MAC:

  • Completely shut down your laptop.
  • Turn it back on by pressing the power button.
  • Now press Command, Option, P, and R keys simultaneously before the grey screen appears.
  • Hold the keys until you hear a sound for the second time and then release them.
  • Done.

This process is only for MAC users, so please do not try this on any other devices.

It will help you decrease fan noise.

Use Laptop in a cold environment

Surroundings play a considerable role.

If you consistently use the laptop in a hot environment, It will heat the hardware which would make the fans run much faster, creating noise that everyone hates.

It is always advisable to use your laptop in cool surroundings if you want the least amount of noise from the fans.

The logic behind this is that if the laptop has an overall low temperature, then it would run all the things efficiently and will not heat up. It will make the fans run at a much slower pace, hence, creating less noise.

In my case, my surrounding very often hot, so I used to go and sit beside an air conditioner to drop the temperature of my machine.

Best Season to use?
Winters are probably the best season to use laptops as you don’t have to care about the temperature. Mother nature has got it figured out for you.

Although, it may not seem like a great thing to do considering the efforts it takes.

Once you compare both of them, you’ll understand how significant changes it brings to the table.

Close Processes running in the background

Killing al the processes that you’re not using in the real-time would take off the load from the system and make it run much faster at a cold temperature. 

It would indirectly make your laptop much quieter & more functional. 

I usually did this every 2 hours or so, and the results were big enough to notice. 

There’s no doubt that everyone has a lot of apps running in the background that are never used.

They’re unnecessarily creating a cluster in the memory. 

Clean Extra Processes in the background

Clearing them from memory is the best thing that you can do to your laptop. 

It is not a very complicated task to do. Anyone can do it. 

  1. Go to the task manager (type it in the search bar) and open it.
  2. Now examine all the processes that are running and clear out the ones that are not in use.
  3. That’s it.

Easy, free, and useful.

Lift up your laptop while using

Fans run faster when e they’re not given enough room to pass the heat.

Most of the people, including me, use their laptops on their laps which doesn’t allow the heat to pass.

It is the leading cause of thermal throttling.

What does the laptop do when it thermally throttles?
Yes, it increases the fan’s speed.

You should lift the laptop from the back for the heat to dissipate in the air.

Even the slightest space would do the job.

For a moment, you would encounter with an increase in the noise levels as the space between the fans and desk creates minimal echo and bounces back the sound.

As the heat starts to go away, the sound will decrease, and the laptop will become silent.

Get it diagnosed in a hardware shop

If you’ve applied all the things mentioned as of now and still the fan is generating a significant noise, then you should get it checked by a technician.
