Laptop fan noise is a problem that many people have to deal with when they are using a laptop. So, what should you do if you discover that your laptop fan is making a loud noise? What is the source of the excessive noise coming from my laptop fan?

In order to establish whether the fan noise is normal, the first step is to examine the fan itself. Nowadays, laptop fans are developed with sophisticated temperature control, which means that the fan speed is adjusted according to the amount of heat being generated. As a result, if you are running a huge game or software, you will notice that the fan sound will become extremely loud. This is normal, and the change in sound will have no effect on the usual operation of the laptop. The computer may generally be used properly as long as it does not have issues with automatic power off and restart, as well as crashes and other issues.

If you put your hand in the cooling vent of the notebook and find that the volume of air leaving the vent is extremely small, this is a sign of an abnormal situation. If the fan makes an obvious collision sound with the blades or if the fan rotates extremely quickly, this is a sign of an abnormal situation.

3 ways to fix your laptop fan noise issue

Method 1: Change the system settings

If there is a physical problem with the fan on a recent laptop, and the fan sound is louder even when the laptop is not running a huge game or programme, it is possible that the problem is caused by the system. You may want to double-check it first. Take a look at how much CPU is being used. Check to see whether everything is in working order before attempting the following way to reduce fan noise by adjusting the system settings:

Take Windows 10 as an example, and the following steps will show you how to adjust the plan settings.

Go to Start > Settings > System> Power & Sleep > Additional power settings in Windows 10 to find out how to achieve this.

Method 2: Clean the fan

As a result, if the fan is making an unnatural noise or making a loud noise and the air volume is little, the fan is most likely clogged with dust, or even inhaling sundries, which results in a low heat dissipation efficiency of the fan, especially for a laptop that has never been cleaned before.

In this circumstance, we typically need to clear the dust from the fan, heatsink, and air vents, as well as remove the dust from the fan. Of course, if you are unable to remove the dust, you can take your laptop to a repair shop where it will be thoroughly cleaned. The sound of the laptop’s fan should be much reduced when it has been cleaned.

Method 3: Replace the fan

You should not just clean the fan on a laptop that has been in use for more than a year, according to my recommendations. Even after cleaning, the heat dissipation performance of the old fan is inferior to that of the new one, so I recommend that you replace it with a newer model.

By using the three ways described above, you should be able to greatly minimize the noise produced by your laptop fan. However, it should be noted that if you need to clean or replace the laptop cooling fan, you will need to reapply new thermal grease to the CPU and GPU.

If you don’t have any previous expertise with fan replacement, I recommend that you take your fan to a repair shop for replacement. If you are using an Ultrabook, replacing the fan is a straightforward process. To replace the fan or clear the dust, you only need to unscrew the back cover of the fan.
