1. An information handling system comprising:
a hardware processor;
a memory device;
a power management unit (PMU) to provide power to the processor and memory device;
an ion emitter/collector blower cooling system including an ion emitter and an ion collector housed within an ion emitter/collector blower housing, the ion emitter/collector blower system being placed at a location within a chassis of the information handling system vertically lower than the hardware processor in the chassis;
an ionic driving circuit operatively coupled to the ion emitter via a high voltage to ionize gases within the ion emitter/collector blower housing and create charged ions that generate an airflow along a voltage field to and through an ion collector; and
an air inlet vent located below the ion emitter/collector blower cooling system and formed in a back surface of the chassis of the information handling system and an air exhaust vent located at an upper exhaust vent location above the ion collector within the chassis of the information handling system so that the airflow is brought into the chassis of the information handling system via the ion emitter/collector cooling system and out of the air exhaust vent where a location of the air inlet vent relative to the upper exhaust vent location of the air exhaust vent in the chassis of the information handling system in a vertical orientation provides convection-enhanced airflow with the ion emitter/collector blower cooling system.
