7.3 Mechanical 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
®
6321ESB ICH thermal solution are shown in Figure 10.
When using heatsinks that extend beyond the Intel® 6321ESB I/O Controller Hub
reference heatsink envelope shown in Figure 10, any motherboard components placed
between the heatsink and motherboard cannot exceed 2.46 mm (0.10 in.) in height.
