40 Thermal/Mechanical Design Guide
6.2 Heatsink Thermal Solution Assembly
The reference thermal solution for the processor is an active fan solution similar to the
prior designs for the Intel® Pentium® 4 and Intel® Core™2 Duo processors. The
design uses a copper core with an aluminum extrusion. It attaches to the motherboard
with a fastener design reused from the RCBFH3 and RCFH4. The clip design is new to
span the larger size of the LGA1366. The thermal solution assembly requires no
assembly prior to installation on a motherboard. Figure 6-1 shows the reference
thermal solution assembly in an exploded view.
The first step in assembling the thermal solution is to verify the fasteners are aligned to
the mounting holes on the motherboard. The fasteners are pressed firmly to lock the
thermal solution to the motherboard.
