Abstract
Airflow in a computer chassis may be enhanced or reduced to affect cooling of heat generating devices using an ionic air moving device. A plurality of ionic air moving devices enhance or reduce airflow through a plurality of fluidically parallel airflow zones of the computer chassis in an airflow direction established by a nonionic air moving device. Each ionic air moving device comprises an ion emitter electrode disposed a spaced distance from a collector electrode, wherein a controller independently controls an electrical potential between the emitter and collector electrodes of each ionic air moving device for affecting the rate of airflow through one or more of the plurality of airflow zones.
