Micro Cooling Fan Wear

"Micro Cooling Fan" fan "the eccentric" is the primary reason is the big noise loud noise loud noise primary reason is the primary reason is the primary cause loud noises. The center of gravity in the axial fan blades, when the job is very smooth, the sound is very small, but with the usual use of wear, a certain error occurs, the focus of the blades is not formed, "the eccentric" in the axis, such "Micro Cooling Fan"change up to the equivalent of one oscillator (oscillator is the motor shaft plus a partial pain round), followed by the use of time becomes longer, the fan bearings gradually wear, stir aggravate noise becomes large. Motor damage: "Micro Cooling Fan" is an easy-to-consuming component, which depicts life after reaching the motor or motor damp several internal short circuit, overload, power surges can lead to motor damage there, such problems attributed to the normal appearance, namely the replacement fan It can handle.
