Why do ultra-thin 2006 cooling fans often have noise problems?

by:TOCH     2021-03-26
For ultra-thin cooling fans, mainly 6mm and 7mm thick, such as 2006, 2507, 3006, 3007, 4006, 4007, etc., users complain most about noise. Why is the thinner cooling fan more prone to noise problems? ? The thinner the cooling fan, the thinner the bearing and the smaller the contact area between the bearing and the shaft core. The high-speed rotating fan blade drives the shaft core to rotate and rubs against the bearing. If the bearing is rougher, the precision is not enough. The greater the noise when the bearing rubs against the shaft core. In order to solve such ultra-thin 2006 cooling fans, after one year of negotiations, we introduced bearings from Hitachi, a Japanese company, and after more than half a year of reliability tests, we finally solved the noise problem of this type of cooling fans.
