ABSTRACT:
A method and apparatus for substantially preventing recirculation of heated air from an exhaust outlet of an expansion card to an air inlet of the expansion card, wherein the air inlet and exhaust outlet are both on the same end of the chassis. The apparatus comprises a chassis with a chassis fan, a motherboard within the chassis having an expansion card connector, and an expansion card in communication with the expansion card connector and secured to the front end of the chassis. The expansion card also includes a card fan configured to move cooling air through the air inlet to the exhaust outlet. An air duct redirects the hot air from the exhaust outlet to prevent recirculation into the expansion card and causes the heated air to exit through the chassis fan. The air duct may include a longitudinal segment through a computer module and a lateral segment selectively securable over the exhaust outlet.
