Abstract
A variable height fan of an information handling system includes a first fan having a first hub and a first plurality of fan blades. A second fan impeller includes a second hub and a second plurality of fan blades. The first hub slides along the second hub as the variable height fan transitions between an expanded position and a collapsed position. Interior edges of the first hub are in physical communication with exterior edges of the second hub, and the second fan impeller drives the first fan impeller through the physical communication between the interior edges of the first hub and the exterior edges of the second hub.
