Abstract: A method is provided for optimizing fan speed control of a computer system that includes a fan unit, a temperature sensor, a control unit to control operation of the fan unit, and a disk storage unit. A forbidden range corresponding to a range for a fan speed is determined based on a relationship between fan speed and vibration of the disk storage unit. An optimized fan control table is generated based on a reference table relating to a relationship between ambient temperature and fan speed. The optimized fan control table is generated by making a part of the ambient temperature values in the reference table change to corresponding to a predetermined fan speed not smaller than a fan speed value corresponding to an upper limit of the forbidden range.
