An adjustable duct system for guiding air flow is disclosed that includes an adjustable duct for guiding air flow. The adjustable duct comprises a perimeter wall that defines an air passage for the air flow, with the perimeter wall defining an entrance opening at the entry of the duct for receiving a flow of air and an exit opening at the exit of the duct for exhausting the flow of air. The perimeter wall includes a bottom wall portion, a top wall portion spaced from the bottom wall portion, and a pair of side wall portions extending between the top and bottom wall portions. The system also includes a movable flap for adjusting an effective area of the exit opening of the perimeter wall to adjust to different sizes of components to be cooled by the air flow.
