An air cooled electronic system within an enclosure simultaneously provides different levels of cooling in response to the individual cooling needs of the various electronic components. In one embodiment, electronic system includes a plenum that has an inlet and a plurality of outlets with the inlet receiving air from outside the enclosure. A rate of airflow at the respective plenum outlets varies as a function of a static air pressure behind the plenum outlets and a shape of the respective outlets, the static air pressure being a function of the shape of a cavity within the plenum. The system also includes a plurality of air ducts respectively coupled to the plurality of plenum outlets, with each air duct having a length and an outlet characterized by an outlet size. A first one of the air ducts has an outlet that is disposed proximate a first subset of the electronic components and a second one of the air ducts has an outlet that is disposed proximate a second subset of the electronic components. The electronic system further includes a blower arrangement disposed within the enclosure that draws external air and blows the air into the plenum.
