Abstract
Detecting failure of a fan of an IHS, including comparing a sound pressure level of an environment noise associated with an environment of the IHS with a threshold; determining, based on the comparing, that the sound pressure level of the environment noise is less than the threshold, and in response: increasing a magnitude of RPM of the fan to correspond to a sound pressure level of a fan noise greater than the sound pressure level of the environmental noise; analyzing a frequency spectrum of the fan noise; determining, based on the analyzing, whether the frequency spectrum of the fan noise includes discrete tones at one or more harmonic frequencies of the fan at the RPM; determining that the frequency spectrum of the fan noise includes discrete tones at one or more harmonic frequencies of the fan at the RPM, and perform an action that is in response to such determination.
