Thermal and Mechanical Design Guidelines

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,  

7-49 for the component drawings. 

 

Four plastic fasteners, see 

Appendix G, Figure 

7-50, 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 

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: 

 

Heatsink/fan mass ≤ 550 g (i.e., total assembly mass, including 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
