Mechanical Specifications
This section documents the mechanical specifications of the boxed processor passive heatsink and
the PWT.
Proper clearance is required around the heatsink to ensure proper installation of the processor and
unimpeded airflow for proper cooling.
7.2.1
Boxed Processor Heatsink Dimensions
The boxed processor is shipped with an unattached passive heatsink. Clearance is required around
the heatsink to ensure unimpeded airflow for proper cooling. The physical space requirements and
dimensions for the boxed processor with assembled heatsink are shown in
Figure 26 (Multiple
Views). The airflow requirements for the boxed processor heatsink must also be taken into
consideration when designing new baseboards and chassis. The airflow requirements are detailed

Boxed Processor Heatsink Weight
this document along with the Intel XeonTM Processor Family Thermal Design Guidelines for
details on the processor weight and heatsink requirements.
7.2.3
Boxed Processor Retention Mechanism and Heatsink Supports
The boxed processor requires processor retention solution to secure the processor, the baseboard,
and the chassis. The retention solution contains one retention mechanisms and two retention clips
per processor. The boxed processor ships with retention mechanism, cooling solution retention
clips, and direct chassis attach screws.Baseboards and chassis designed for use by system integra-
tors should include holes that are in proper alignment with each other to support the boxed proces-
sor. Refer to the Server System Infrastructure Specification (SSI-EEB) at http://www.ssiforum.org
for details on the hole locations. Please refer to the “Boxed integration notes” at http://sup-
port.intel.com/support/processors/xeon for retention mechanism installation instructions. Retention
mechanism clips must interface with the boxed processor heatsink area shown in Detail A in
FigureThe retention mechanism that ships with the boxed processor is different than the reference solu-
tion from Intel. Please refer to
Figure 24 below, which contains the dimensions for the reference
solution. Please refer to
Figure 25 for the retention mechanism that ships with the boxed processor.
