This article mainly shows you "what to do if the fan noise of the notebook computer is too loud". The content is simple and clear. I hope it can help you solve your doubts. Here, let the editor lead you to study and learn the article "what to do if the fan noise of the laptop computer is too loud?"

The reason for the high noise of laptop fans:

1, the use time is too long, the fan coil is aging, lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The fan accumulates too much dust or the fixing screw is loose, which leads to the position shift.

4. the problem of power supply.

Notebook fan loud sound solution:

1. Remove the dust

In general, newly bought fans always have less noise and become significantly larger after a period of use. In fact, dust is one of the important reasons for the rise in fan noise, because all-pervasive dust can always get into an incompletely airtight chassis. When the CPU fan rotates at high speed, the whirlpool effect makes it easy for dust to attach to the fan. There is no doubt that it is necessary to remove and clean the CPU fan at this time, and when cleaning the dust, we should pay attention to the gap between the back of the fan and the heat sink, which is the easiest to forget.

2. Add lubricating oil

For oil bearing fans, it is common for motor drive shafts to become inflexible after working for a long time. For this reason, it is recommended that you add lubricating oil in this position and recommend mechanical lubricating oil or gasoline engine oil. Of course, you must be careful not to let it spill when adding lubricating oil.

3. Reduce vibration

In addition, the vibration problem also needs our attention. Usually, the high-speed rotating fan will collide with the heat sink at high frequency. If the fan and the heat sink are stable and suitable, the vibration and noise caused by the collision can be greatly reduced. For example, holding a high-speed rotating CPU fan in your hand, the noise is much less than that fixed on the heat sink, because the soft hand absorbs a lot of vibration. According to this principle, adding a soft gasket (such as leather and rubber) with a thickness of 1mm to 2mm between the four corners of the fan and the radiator can effectively reduce the noise caused by the vibration of the fan and the radiator.
