How to Fix Laptop Fan Making Loud Noise? Laptop fan noise is a problem that many users face while using a laptop. So when you find that your laptop fan is making a loud noise, how to fix it? Why is my laptop fan so loud?
The first step is to determine whether the fan noise is a normal sound. Today’s laptop fans are designed with intelligent temperature control, ie they adjust the fan speed according to the heat. So you will find that when you run a big game or software, the fan sound will be very loud, this sound change is normal, and this change will not affect the normal operation of the laptop. As long as the computer does not automatically shut down, restart, crash or other problems occur, it can be used normally.
But there is a case that the fan makes an abnormal scratching sound when rotating, that is, there is a clear banging sound of the fan blades or the sound of the fan is very loud, but you put your hand into the laptop’s cooling vent and find that the outlet The amount of air is very small, so this situation is unusual.
3 Ways to Fix Your Laptop Fan Noise Problem
Method 1: Change System Settings
For new laptops, if there is a physical problem with the fan, if the fan is loud without running large games or software, it may be caused by the system. You can check first. Take a look at CPU usage. If all is well, try the following method to reduce fan noise by changing system settings.
To change the scheme settings, you can do as follows, take Windows 10 as an example
1. Windows 10: Go to Start > Settings > System > Power & sleep > Additional power settings
2. Click on “Change Plan Settings”
3. Click on “Change advanced power settings”
4. Click “CPU Power Management”, then click “System Cooling Policy” in the drop-down menu, then click “Enabled”, change “Enabled” to “Disabled”, and click OK.
Here the setup is complete. You will now find that the fan noise should have reduced considerably.
Method 2: Clean the Fan
If the fan noise is abnormal or the sound is loud, and the air volume is low, this situation is usually a lot of dust on the fan, or even breathing in all kinds of things, resulting in the fan Having low heat dissipation efficiency, especially for laptops that have 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, no matter if you can’t clean the dust, you can go to the repair shop to clean your laptop. Once the laptop is clean, the sound of the fan should be fairly quiet.
Method 3: Replace the Fan
If your laptop has been in use for more than a year, I would not recommend cleaning the fan alone. 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.
Using the above three methods, you can significantly reduce the noise of your laptop fan, but it should be noted that if you need to clean or replace the laptop fan, you will need a new one on the CPU and GPU. Thermal grease should be applied.
If you have no experience with fan replacement, I suggest you go to a repair shop to have the fan replaced. If you’re using an Ultrabook, it’s pretty easy to replace the fan. You only need to remove the bottom cover to replace the fan or clean the dust.
