5 ways to reduce laptop cooling fan noise

The noisy laptop cooling fan is extremely uncomfortable and can signal potential problems with your device. Whether dusty, overloaded by background processes or difficulties due to the old ingredients, you can reduce the noise of the fan on the laptop with the following useful tips.

Turn off unnecessary background processes

When your CPU or GPU is active, the cooling fan in the laptop will rotate to cool the components and prevent the Thermal Throttling or the potential damage. This is absolutely normal in tasks that require a lot like playing games or editing videos, so you don't need to worry in those cases.

However, unnecessary background processes can increase the load on the laptop, causing the fan to work more than necessary. To solve this problem, you can start by identifying and closing any process you do not need.

If you have a Windows laptop, you can close the background processes not as necessary as Task Manager, where you can control any applications that can occupy too much resources. You can do the same on the Macbook using Activity Monitor. Linux users can also use some tips to turn off malicious processes.

Use software to adjust the fan curve

If the laptop cooling fan is still loud, you can adjust the fan speed manually by a third party application, but remember that this comes with disadvantages. Because the fan curve is reduced affecting the cooling capacity of the laptop, you may face Thermal Throttling in CPU or GPU. Your device deliberately slow down to avoid overheating, protect the hardware from damage.

Software should only be used to adjust the laptop fan curve if you do not use laptops for activities that require heavy handling, such as video editing, output, etc. Used for light activities such as email checking and editing documents, adjusting the laptop fan curve to reduce the noise of the cooling fan is an appropriate choice.

There are many fan control applications for laptops running Windows, but compatibility may vary significantly between manufacturers, because some laptops have fans that cannot be manually adjusted. Some devices, especially gaming laptops, also allows you to control the fan curve directly from BIOS, so you should check there before switching to third -party applications.

If you are using a Macbook, you can adjust the fan curve with MACS Fan Control, while for Linux laptop, you can manage the fan speed with the fancontrol utility.

Laptop cooling fan hygiene

If your laptop cooling fan is constantly running, that means the laptop is constantly hot. Dust and hair accumulated are inevitable and only reduces the airflow, tying a laptop cooling fan to run more often. The decreasing air flow means poor heat dissipation, so you will need to clean the craft laptop to improve the air flow, thereby improving the ability to cool down.

Warning: If your laptop is still within the warranty period, the opening of the device can cause warranty loss (including after -sales expansion warranty like AppleCare). Moreover, you can damage the components if you do not know what you are doing. So, be careful or consult a friend who is a bit more experienced.

To clean the laptop cooling fan, you will need a compressed air, a broom, a screwdriver and patience to open your laptop. Although the possibility of damage is very low, you should also wear antistatic bracelets to prevent not damage any component.

After opening the laptop, clean the fan, especially if they are dusty. Use short pneumatic streams to blow away the dust and brush the rotor to remove all remaining debris. During implementation, take advantage of the opportunity to clean the vents and radiators. If you encounter stubborn sediments that cannot be removed, a small amount of Isopropyl alcohol may help. Just make sure that area is completely dry before connecting the laptop to the power source.

Replace laptop cooling fan

If the laptop cooling fan suddenly emits an unusual sound and a loud cramp or a loud sound, it is having a problem. The first step is to clean the fan and remove all fan debris. If the problem continues, you may need to replace the laptop fan.

The incident may be due to the axle in the fan. The solution to this problem is almost always changing the fan. Although the axle can be repaired, it may take more time than buying and installing a replacement fan.

The replacement of a new fan is not difficult, but it is not an easy task for anyone who is not used to repairing laptops. Although the basic principle is still the same on all laptops, models from different manufacturers will have different implementation processes.

Finding a replacement fan for specific laptop models can also be difficult and in some rare cases, your only option may be to bring the device to the First Service Center.

Glue is a special compound applied between CPUs or GPUs and radiators. It fills small gaps, ensuring better contact and helping to transfer heat from the processor more effectively.

If you have an old laptop used a lot, thermal glue may have been dry, making the heat transfusion worse. Although the replacement of thermal glue can be helpful, you should only do it if you are confident to work with the components inside the laptop and have done the same thing before. If not, take the device to the repair shop and let the experts handle.

After applying the new thermal glue, you will see your laptop cooling better, helping the fan run smoothly.

If the above steps are not effective or you are uncomfortable when opening the laptop, it is best to bring the device to the service center. For MacBook, you can schedule an appointment at Genius Bar, while for Windows or Linux laptops, you will need to contact the manufacturer because of the different repair policy depending on the brand.

Before repairing, you should consult the price first. You can find a better price at a reliable third -party repair store, although the results may be different, especially if you have a MacBook, because it is difficult to find an alternative component.
