The knowledge points of this article "how to reduce the noise of computer fans" are not quite understood by most people, so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to reduce the noise of computer fans" article.

What should I do when the sound of the notebook fan is big and sometimes small?

When the notebook is in use, the sound is loud and sometimes small, and many people are worried about whether there is something wrong with it. In fact, if it rings every other time, it is normal. It is mainly because the heat dissipation of the notebook is not good, so the CPU fan will make a noise. But if it is a very short interval and continuous sound (about 2 minutes in an average of 3 or 4 times), it is not normal, this may be a problem with the video card driver, large heat dissipation, need to be dealt with. Notebook fan sound is a very common problem, as long as the normal use of computers for 2 years, all will appear, if the use of environmental dust more time will be in advance, generally speaking, the most important thing is the accumulation of dust, but there is also a coil aging and lack of oil, which requires everyone to check and rule out their own computers, if they really do not know how to deal with, you can find maintenance center personnel for help.

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.

The above is about the content of this article on "how to reduce the noise of computer fans". I believe we all have a certain understanding.
