Abstract:
1. A method for managing a fan system in an information handling system (IHS), the method comprising: providing a fan system comprising: identifying a first critical range of fan speeds at which a tonality exceeds a predetermined tonality threshold, the predetermined tonality threshold being one of a plurality of tonalities of airborne noise produced by the fan system; identifying a second critical range of fan speeds at which a hard drive throughput falls below a predetermined hard drive throughput threshold based on fan vibrations; generating a system fan speed request; adjusting the first fan speed to avoid the first critical range and the second critical range when the system fan speed request falls within the first critical range or the second critical range; managing the second fan speed to avoid the first critical range and the second critical range; and adjusting the system fan speed to meet the system fan speed request.
