ABSTRACT:
A system, fan controller and method for enhanced alert notification. Embodiments provide an effective mechanism for utilizing system fans to create alert tones or messages, where fan speed differentials may be adjusted to alter the frequency of the fan interference sounds. As such, existing hardware can be used to reduce cost by producing audible alerts which may be heard above ambient noise in a room with one or more electronic systems. Further, the frequency of the interference sounds may be altered to more clearly identify one or more systems to which a fault pertains.
