Thermal/Mechanical Reference Design
28 64-bit Intel® Xeon™ Processor with 2MB L2 Cache Thermal/Mechanical Design Guidelines
If other custom heatsinks are intended for use with the 64-bit Intel Xeon Processor with 2MB L2
Cache, they must support the following interface control requirements to be compatible with the
reference mechanical components:
• Requirement 1: Heatsink assembly must stay within the volumetric keep-in.
• Requirement 2: Maximum mass and center of gravity.
Current maximum heatsink mass is 1000 grams [2.2 lbs] and the maximum center of gravity 38.1
mm [1.5 in.] above the bottom of the heatsink base.
• Requirement 3: Maximum and minimum compressive load.
Any custom thermal solution design should meet the loading specification as documented within
this document, and should refer to the datasheet for specific details on package loading
specifications.
