Many products, are required to cooling fan more silent, if there is no sound better, then, how to choose the cooling fan manufacturer to do more silent?

1. The voltage can be designed lower, such as 5V, 12V, because the same size of the cooling fan, low-voltage design, the speed can be made lower, the operation of the sound is smaller!

2. Larger size design, smaller speed design, quieter sound.

3. The use of double ball bearings can keep the cooling fan working quietly for a long time, and it is not easy to appear abnormal sound.
