Abstract
A system and method for cooling components and a chassis in a portable information handling system includes a pressure barrier that divides the chassis into a plurality of zones, an evacuative fan in a first zone to generate airflow across components to cool the components and a hyperbaric fan in a second zone to increase air pressure in the second zone. The pressure barrier may provide thermal isolation, acoustic dampening and electromagnetic insulation. A controller communicatively coupled to the fans can operate each fan independently to cool components for improved performance and maintain a surface temperature of the chassis below a temperature for user comfort.
