Abstract
Dual operation centrifugal fan apparatus and methods of operating same that may be used, for example, to cool the internal heat-generating components of an information handling system or other device. The dual operation centrifugal fan apparatus may be implemented in one embodiment as a self-cleaning blower apparatus that is operated in a first normal cooling direction to dissipate heat from internal components of an information handling system, and operated in second cleaning direction to reverse airflow and expel accumulated dust from the interior of the information handling system.
