In an information handling system, positions of a plurality of mechanical structures may be configured to be controlled to selectively direct airflow cooled by first heat-rejecting media and a thermoelectric cooler between flowing through the first exhaust plenum and flowing proximate to the one or more information handling resources and selectively direct airflow heated by the second heat-rejecting media and the thermoelectric cooler between flowing through the second exhaust plenum and flowing proximate to the one or more information handling resources.
