A computer system or other electronic system includes a plurality of cooling fans configured to operate in parallel. The cooling fans are operated in a manner to decrease the operating time of a fan. The cooling fans can alternate in operation. Thus, operating time is more equally divided between the two cooling fans and the hours of operation and number of rotations of the fans is more nearly equal. In an embodiment to reduce noise, two fans run at a lower speed instead of one fan at a higher speed. In an embodiment, a fan operates with a reduced speed which maintains a desired operating temperature. In an embodiment a thermal table is stored in BIOS (basic/input output system).
