Wedges of sound absorbing material are located at an open end of a plenum with the points of the wedges directed into the plenum toward a blower. Each wedge extends across the opening of the plenum. The wedges are slightly spaced apart at their wide ends and their sloping faces are curved to form venturies for the air from the blower. The venturies give the air a high velocity that is suitable for cooling circuit components such as memory cards.
