"Micro Cooling Fan" noise: the fan rotor assumptions change physical centroid and inertia of the rotor shaft in the middle are not on the same axis, it would constitute a rotor imbalance. Physical centroid and the shaft of the rotor inertia ratio of middle distance interval is called the eccentric rotor does not balance constitute the eccentric distance, when the rotor change because the effect of centrifugal force effect force attack on a shaft mount constituted oscillation, and the oscillation via base way transfer to the various parts of machinery.
"Micro Cooling Fan" the use of life expectancy: life expectancy using fan means trouble-free operation time radiator product of the normal operation, the use of high-quality products in general life expectancy can reach tens of thousands of hours. In price and functionality similar situation, the selection of the number of life-long use of the product was significantly better safeguard our investment. "Micro Cooling Fan" by a number of life: motor life expectancy, use of the environment, power supply and other aspects of the elements of the composition.
