Professional manufacturing and production of radiator cooling fans, condenser fans and fan motors, etc.

How to design a cooling fan, can achieve prevent noise

A lot of people in the use of a cooling fan, often someone feedback that there will be noise, but the cooling fan, is a special production technology for processing, the main way of improvement is the following:

the cooling fan bearings, USES is auto bearing, compared with the ordinary bearing, it really can reduce a lot of noise; Also, by improving the cooling fan blade rotation balance issue, when the blade balance coefficient do is smaller, it has better balance, then the cooling fan is more stable when using, also reduces the noise generated.
