Patent ID: 8027160

Claim:
A system for removing heat from an electronic component associated with an information handling system, the electronic component having a hotspot, the system comprising: a mass providing a heat sink to the electronic component; a set of extended surfaces for transferring heat from the mass; the set of extended surfaces defining a primary flow direction for a cooling fluid; a first subset of the set of extended surfaces having a first length measured in the primary flow direction; a second subset of the set of extended surfaces having a second length measured in the primary flow direction; each of the first and second subsets of extended surfaces including one or more extended surfaces; and the second subset of extended surfaces disposed closer to the hotspot of the electronic component than any other subset of the set of extended surfaces; wherein the second length is less than the first length such that a flow rate of the cooling fluid through the second subset of extended surfaces is greater than a flow rate of the cooling fluid through the first subset of extended surfaces.
