7.3Mechanical Design Envelope

While each design may have unique mechanical volume and height restrictions or implementation requirements, the height, width, and depth constraints typically placed on the Intel 5000 Series chipset MCH thermal solution are shown in Figure 7-2.

When using heatsinks that extend beyond the chipset MCH reference heatsink envelope shown in Section 7.2 any motherboard components placed between the heatsink and motherboard cannot exceed 2 mm (0.07 in.) in height.
