Claim Text:
1. An information handling system comprising: a chassis; a processor disposed in the chassis and processing information; memory disposed in the chassis and in communication with the processor to store the information; a cooling fan disposed in the chassis to generate a cooling air flow over the processor; a vibration detector disposed at the cooling fan to detect vibration of the cooling fan; and a vibration source integrated into the cooling fan and in communication with the vibration detector, the vibration source creating a vibration without creating a cooling airflow, the vibration canceling at least a portion of the cooling fan vibration detected by the vibration detector, the vibration source creating a vibration having an amplitude of less than a detected vibration of the cooling fan so that the resolution of the cooling fan vibration and the vibration source vibration provides a reduced adjusted vibration, the vibration source initiating vibration based upon a cooling fan motor position and direct current voltage, the generated vibration subsequently adjusted based upon detected vibration.
