Zusammenfassung:This invention relates generally to a heat dissipation system and method for an integrated circuit assembly, and more particularly to a system and method of dissipating heat from an integrated circuit device. A heat dissipation system and method for extracting heat from an integrated circuit device includes, in one example embodiment, a thermally conductive base plate. The heat dissipation system and method further includes an array of substantially parallel fin structures having top and bottom portions. The thermally conductive base plate is attached to the array such that the thermally conductive base plate is in close proximity to the bottom portion. The top and bottom portions extend outwardly from the thermally conductive base plate. The top portion of the array further extends laterally beyond the bottom portion of the array. The top and bottom portions of the array are of sufficient size so as to allow components on a motherboard to encroach around the integrated circuit device.
