My laptop fan makes a lot of noise

Laptops, unlike desktops, have less ventilation due to their designs. Therefore, it is important to regularly check the fans, in order to keep the computer at an adequate temperature. If the equipment begins to generate too much noise, there may be a problem with them and they should be checked.


Doing a simple internet search for “my computer makes a lot of noise”, you will probably find that the component that causes it is, generally, the fan or fans that are responsible for cooling the board and its components.

If you want to know why the HP laptop fan makes a lot of noise or learn how to clean the ASUS laptop fan, for example, we invite you to consider the information contained in this space, since we offer you several tools with which you could minimize or disappear completely the problem.

Most common reasons causing excessive laptop noise

The causes or reasons why the noise of the fan in a laptop exceeds the comfortable levels for the user can be separated into two categories, which we will review below to help you more easily identify what is causing the problem:

in hardware

As mentioned above, in most cases, the ventilation system is the cause of noise in a laptop, since the revolutions at which the fans work can be more or less intense, depending on the capacity of each fan. equipment.

However, a computer with a lot of ventilation sometimes also has its disadvantages, since they allow more dirt to enter, thus covering the grilles, fan blades and other elements of the motherboard. This situation can lead to various inconveniences, including excessive noise.

in software

In laptops, ventilation plays a fundamental role, which is why many have software dedicated to constantly analyzing the temperature of key parts such as the processor and graphics card, allowing the status of each to be known in real time.

When the equipment is working excessively, these parts heat up and, in turn, activate alarms in the computer system, sending the order to the fans to work more intensely.

How to reduce the noise level on a laptop

Cleaning the inside of your laptop is one of the most direct and effective methods to reduce laptop fan noise; since, in most cases, the accumulation of dirt is one of the reasons that generate annoying noises.


take off the lid

The first step in cleaning your computer’s fans is to remove the bottom case cover, depending on your PC model. For this you must find and remove all the screws that are in sight, and even check if there is any under the security and warranty labels.

When removing them, you will notice that the lid loosens and with the help of a plastic trowel or your own nails, carefully lift it to unlock the tabs that hold it.

Disconnect components

Whether your laptop has a small, medium, or large fan, it will always be connected to the computer’s motherboard, so you’ll need to carefully pull the cable out, making sure not to pull on the bracket, but on the plastic connector. If it is very small, you can help yourself with plastic tweezers that do not conduct electricity.

In addition to disconnecting the fans, you must also remove the cables from the Wi-Fi antenna and the battery, RAM memory and hard drive, either HDD or SSD, as security measures, to avoid damage or short circuits to the board.

Uninstall the heatsink

One of the most notable elements when you remove the cover of the computer is the heatsink, which will have a kind of bronze-colored tubes that circulate through certain areas of the plate. This part is responsible for cooling the processor and graphics card, preventing them from reaching dangerous levels.

Here, you should also find the fan of the laptop completing the ventilation circuit and you will have to locate the screws that hold the support casing to the heat sink, to remove them and be able to remove the fan. This will allow you to handle it more easily, as well as being able to access all the nooks and crannies where there is accumulated dust.

Clean the fans

You can clean the laptop fans with the help of a brush to remove dust, although you can also use swabs dipped in alcohol if you want to make them shine. In addition, another quite useful tool is compressed air bottles, since you can activate them near the grids and expel dirt particles with pressure.

However, even if you have the best pressure washer at home, the application of water, detergent or combinations to clean the laptop fan is not recommended at all, as it could damage the motor and render it unusable by causing a short circuit.


Mounting the sink

When you have finished cleaning the fans, you will have to mount the heatsink again, but first, make sure to apply a new dose of thermal paste to both the processor and the graphics card, after having completely removed the remains of the previous one.


Finishing the cleanup

To finish, plug each component back into place and blow a few blasts of compressed air into the corners, to blow out any leftover particles inside.

If the problem is software:

On the other hand, if you suspect that the noise problem on your PC due to the fans is due to a software problem, you can access the Task Manager by pressing the Ctrl + Alt + Del keys, and thus verify if there is any program that is consuming too many resources and, as a consequence, making the team work excessively.

You can check this by taking a look at the Performance tab, where you will be shown detailed information about the operation of each essential piece of hardware.
