Intel® 6321ESB ICH—Reference Thermal Solution

7.5Torsional Clip Heatsink Thermal Solution Assembly

The reference thermal solution for the Intel® 6321ESB ICH component is a passive heatsink with thermal interface. It is attached using a clip with each end hooked through an anchor soldered to the board. Figure 12 shows the reference thermal solution assembly and associated components. The torsional clip and the clip retention anchor are the same as the one used on the Intel® E7500/E7501/E7505 and 3100 chipset reference thermal solutions.

Full mechanical drawings of the thermal solution assembly and the heatsink clip are provided in Appendix B, “Mechanical Drawings”. Appendix A, “Thermal Solution Component Suppliers” contains vendor information for each thermal solution component.
