Noise caused by the cooling fan 4 major reasons
Noise generated by cooling fans can not be avoided, the source of the Wind is using the technology allows the fan to minimize the noise that regard,So noise is how to generate it?There are four points:
1、Cooling fan used by the bearing quality is not good, the current market is the best ball bearing is NMB bearing;
2、The fan blade's weight is not uniform, resulting in a shock;
3、The fan shape of the unreasonable design of wind resistance is too large;
4、Fan speed is too high.
