Recently, many of my friends have asked me a question: why is my laptop fan so loud? Generally speaking, the newly laptop fan is less noisy and will become larger after one or two years of use. This post provides some tips to solve the noise of notebook fans.
Part 1: Why is the fan so loud on laptop
In terms of power saving and noise reduction, the notebook generally only starts to rotate when the temperature reaches the predetermined value of the BIOS. And often it is not full operation, it is divided into several speeds to run, when the temperature is lower than the predetermined value, it will automatically stop running. After using the laptop for a period, it will produce noise, which is especially noticeable when the notebook is overloaded.
When the laptop is turned on, the fan will be turned on for hardware self-test, so maybe laptop making noise when switched on.
Most of the biggest noise comes from the notebook cooling fan. When the notebook is used for a long time or the working environment is dusty, a large amount of dust accumulates inside the fan. When the fan rotates, due to the blockage of dust, not only the laptop fan sounds loud, but sometimes the floc will entangle the fan blades and the fan will not work properly.
Laptop fans should be cleaned regularly to avoid damage to other hardware due to excessive temperatures.
Part 2: How to fix the laptop fan making noise
1. Clean dust
Dust is one of the important causes of fan noise. In general, new computer fans are always less noisy, and will become significantly larger after a longer period of use, especially in computers with more dusty work environment.
When the CPU fan rotates, the vortex effect makes it easy for dust to adhere to the fan.
At this point, we removed the fan and it was necessary to clean it with a hair dryer and a small brush.
Note: The crack between the back of the fan and the heat sink is the easiest place to forget. Don't forget to clean it when you are dusting.

2. Add lubricant
For oil-impregnated bearing fans, the motor drive shaft becomes inflexible after along period of work causes making noise sound when the fan running.
It is recommended that you add lubricants at the bearing locations. Be careful when adding lubricants. Don't add too much.
Add lubricant to your laptop fan:
1.Remove the fan blade from the fan and clean the fan.
2.Apply lubricant to the reel motor and the fan blades.
3.Fasten the fan blades. After handling the fan, it is best to clean the heatsink and the silicone grease on the CPU (graphics card) and add new silicone grease.
3. Reduce vibration
After the above two methods of the laptop fan noise problem has not been solved. It is necessary to consider the fan vibration problem, usually the high-speed rotating fan will have a high-frequency collision with the heat sink. If the fan and the heat sink are then properly stabilized, the vibration noise generated by the collision can be greatly reduced.
Check that the fan screws are secure.
Foam sponges are used to reduce vibration and check if the foam sponge is still there. If not, it is recommended to replace the new laptop fan.
4. Buy an external cooling fan
The notebook cooler is a very convenient component to use, and a board plus a fan helps maximize the use of airflow to cool the laptop motherboard.
They also have variable wind speeds, temperature sensors and built-in USB hubs. If you're using a laptop on your desktop or other static location, playing demanding 3D games, rendering video the cooler is the ideal choice.
It can temporarily solve the problem of fan noise and overheat.
5. Kill the process
