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 E8500 chipset NB thermal solution are shown in Figure 7-2.

When using heatsinks that extend beyond the NB reference heatsink envelope shown in Figure 7-2, any motherboard components placed between the heatsink and motherboard cannot exceed

4.14 mm (0.16 in.) in height.
