Abstract: An anchor base for a heat sink for an IC chipset is formed basically in a rectangular frame comprising: two lateral plates respectively formed at the bottom of two opposite lateral stiles of the rectangular frame, each of the two opposite lateral plates having a respective snap barb at its lower portion; a longitudinal resilient rod bridging the other two opposite lateral stiles of the rectangular frame, wherein two ends of the longitudinal resilient rod are extended downwardly to form a pair of protruding rods which are no shorter than the height of the lateral plates; a shorter resilient rod crossing the longitudinal resilient rod; wherein a protrusion is formed at the bottom of each of two ends of the shorter resilient rod. Thus, an anchor base for a heat sink can be made without any extra perforation or cutting steps.

Abstract: A heat sink dissipater includes a retaining device and a heat dissipater. A plurality of fins and a plurality of pads or recesses are integrally formed on the top surface of the heat dissipater. A plurality of resilient legs extend inward from the sides of the retaining device. Retaining edges are also formed on two sides of the retaining device. The resilient legs fall into the gaps between the fins when the retaining device is positioned on the heat dissipater to secure a CPU assembly. In an orientation, the legs are placed on the pads or recesses of the heat dissipater and in an orthogonal orientation, the legs are placed directly on the top surface of the heat dissipater. Therefore, CPU assemblies of different thickness can be accommodated by rotating the retaining device or the heat dissipater 90 degrees.
