Abstract
A method of operating an apparatus for use with a computer, including a power source, a system board, and a heat sink. The method includes operating a fan reversing control card, which is coupled to the system board, to generate normal and reverse cycle rotation signals in predetermined intervals, and controlling a fan, which is coupled to the fan reversing control card, by receiving the normal and reverse cycle rotation signals, and operating in normal and reverse cycles in which the fan rotates in first and second directions, respectively. The method further includes installing the fan within the computer sufficiently proximate to the heat transfer surfaces such that the first and second directional rotations of the fan generate air flows in first and second directions with respect to the heat transfer surfaces, respectively.
