Abstract

An information handling system includes a powered hardware processor and a memory device. The information handling system includes an ion emitter/collector blower cooling system including an ion emitter/collector blower having an ion emitter and an ion collector, the ion emitter/collector blower being operatively coupled to a fan and located between the fan and an exhaust vent formed in a top edge of the chassis of the information handling system. An ionic driving circuit is operatively coupled to the ion emitter via a high voltage to ionize gases at the ion emitter/collector blower to create charged ions that generate an airflow to and through the ion collector. The information handling system also includes an air intake vent located at the fan in the chassis so that the airflow is brought into the chassis via the fan, through the fan and ion emitter/collector blower, and out of the air exhaust vent.
