Abstract
An apparatus for predicting fan wear-out and impending failure and a method of manufacturing the same. One embodiment provides for (1) a lookup table containing expected fan speeds at given duty cycles; and (2) a processor for comparing a measured fan speed at a given duty cycle with an expected fan speed at the given duty cycle, the processor generating a predicted fan wear-out and impending failure.
