It is found that many customers care about the noise of the cooling fan when they choose the cooling fan. The quieter the fan is, the more acceptable it is. Too much noise will easily affect people's normal life. What are the main factors of the noise of the cooling fan?

The greater the air volume of the cooling fan, the greater the noise. Another point is that it has a great relationship with the bearing. When the oil bearing starts to use, it will not find much noise. In the later stage, when the lubricating oil dries up, the noise of the fan will become more and more loud. The fan with double ball bearing is quieter, and there will be no too much noise in the later use, It has longer service life than oil and is more silent. Double ball bearings are more expensive than oil-bearing ones. When selecting cooling fans, you can choose bearings according to their own products.
