Abstract:
1. A method for reducing vibration in an electronic system comprising at least one fan for cooling the electronic system and at least one memory disc drive that is susceptible to performance degradation around a resonant frequency of the at least one memory disc drive, said method comprising: determining the resonant frequency of the at least one memory disc drive; measuring a temperature of the electronic system at run time; determining a desired operational frequency of the at least one fan based upon the measured temperature of the electronic system; determining whether the desired operational frequency of the at least one fan is the resonant frequency of the at least one memory disc drive; and operating the at least one fan at a frequency other than the desired operational frequency in response to a determination that the desired operational frequency is the resonant frequency of the at least one memory disc drive during run time of the electronic system.
