A ventilation unit (10) for operative arrangement within an electronic apparatus. This unit has: an exterior side (18) having a first exhaust port (32) separated from, and located in stacked relationship with, a second exhaust port (34); and a first (22) and second (24) powered air mover, each having an intake side (25, 26) oriented at an angle greater than zero degrees from the exterior side. The first powered air mover intake side (25) is in communication with the first exhaust port (32). One powered air mover can be located closer to the exterior side than the other. Gas, such as air, removed from the electronic apparatus can be drawn in through an intake side (26) of the second powered air mover (24), then directed through a duct cover (40) before it flows between a covered side (27) of the first powered air mover (22) and a support member (12) side of the unit. The angle of orientation is preferably between twenty and one hundred degrees. Additional powered air movers can be accommodated, each with a respective exhaust port. Also, a ventilation unit (10) with an exterior side (18) having first (32) and second (34) exhaust ports; the exterior side (18) being adjacent a support member side (12) to which a second powered air mover (24) has been secured. A first powered air mover (22) is included in communication with the first exhaust port (32). The first powered air mover (22) can have a first covered side (27) opposite an intake side (25). Gas drawn in through an intake side (26) of the second powered air mover (24) flows between the first covered side (27) and the support member side (12) before exiting the second exhaust port (34). Additionally, a method of venting thermal energy generated within an electronic apparatus through an exterior side (18) of a ventilation unit (10) operating within the apparatus. This method comprises the steps of drawing air in through a first intake side (25) of a first powered air mover (22) and out a first exhaust port (32) of the exterior side (18), separately from drawing air in through a second intake side (26) of a second powered air mover (24) and out a second exhaust port (34) of the exterior side (18) located in stacked relationship with the first exhaust port (32).
