The mechanical interface with the reference attach mechanism is defined in Figure 22
and
Figure 23. Complying with the mechanical interface parameters is critical to
generating a heatsink preload compliant with the minimum preload requirement given
in Section 2.1.2.2.
Additional requirements for the reference attach mechanism (clip and fasteners)
include:
• Total assembly mass, including heatsink/fan mass (≤ 550 g), clip and fasteners
< 595 g
• Whole assembly center of gravity ≤ 25.4 mm, measured from the top of the IHS
⎯ Whole assembly = Heatsink + Fan + Attach clip + Fasteners
