Mechanical Interface to the Reference Attach Mechanism
The attach mechanism component from the reference design can be used by other 3
rd
party cooling solutions. The attach mechanism consists of:
•
A metal attach clip that interfaces with the heatsink core, see Appendix G,
Figure 7-48 and Figure 7-49 for the component drawings.
Figure 7-48 and Figure 7-49 for the component drawings.
•
Four plastic fasteners, see Appendix G, Figure 7-50, Figure 7-51, Figure 7-52 and
Figure 7-53 for the component drawings.
Figure 7-53 for the component drawings.
The clip is assembled to heatsink during copper core insertion, and is meant to be
trapped between the core shoulder and the extrusion as shown in Figure 6-6.

The mechanical interface with the reference attach mechanism is defined in Figure 6-7
and Figure 6-8. 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:
include:
•
Heatsink/fan mass ≤ 550 g (that is, total assembly mass, including clip and
fasteners < 595 g
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
