How to Fix Laptop Fan Making Loud Noise

Laptop fan noise is an issue that many users have to face when using a laptop. So, when you find your laptop fan making a loud noise, how to fix it? Why is my laptop fan so loud?

The first step is to determine if the fan sound is a normal sound. Today’s laptop fans are designed with intelligent temperature control, that is, adjust the fan speed according to the heat. So you will find that when you run a large game or software, the sound of the fan will be very loud. The change of this sound is normal, and this change will not affect the normal operation of the laptop. As long as the computer does not have automatic power off, restart, crash, or other issues, it can generally be used normally.

But there is a case that the fan has an abnormal scratching sound when it is rotating. That is, the obvious collision sound of the fan blades or the fan sound is very fast, but you put your hand in the notebook’s cooling vent and find that the outlet air volume is very small, so this situation is abnormal.

3 ways to fix your laptop fan noise issue

Method 1: Change the system settings

For a newer laptop, if there is a physical problem with the fan. If the fan sound is louder without running the large game or the software, then it may be caused by the system. You can check it first. Take a look at the CPU usage. If everything is fine, try the following to reduce the fan noise by changing the system settings.

Method 2: Clean the fan

If the fan is abnormal or loud and has a low airflow, this is usually the case with too much dust or even sucking in debris on the fan, resulting in low heat dissipation efficiency of the fan, especially for a laptop that has never been cleaned before.

For this situation, we usually need to clean the dust from the fan and heatsink and remove the dust from the air vents. Of course, it doesn’t matter if you can’t clear the dust. You can go to the repair shop to clean your laptop. After the laptop is cleared, the sound of the fan should be much smaller.

Method 3: Replace the fan

If your laptop has been in use for more than a year, I don’t recommend that you only clean the fan. Even after cleaning, its heat dissipation performance is not as good as the new one, so I suggest you replace it with a new one.

Through the above three methods, you should be able to significantly reduce your laptop fan noise, but if you need to clean or replace the laptop fan, you need to apply new thermal grease to the CPU and GPU.

If you don’t have experience in replacing fans, I suggest you go to a repair shop. If you use an ultrabook, replacing the fan is very simple. You only need to remove the bottom cover to replace the fan or clean the dust.
