Thermal/Mechanical Reference Design
2.5.4 Assembly Overview of the Intel Reference Thermal
Mechanical Design
The reference design heatsinks that meet the Quad-Core Intel® Xeon® Processor 5400
Series thermal performance targets are called the Common Enabling Kit (CEK)
heatsinks, and are available in 1U, 2U, & 2U+ form factors. Each CEK consists of the
following components:
• Heatsink (with captive standoff and screws)
• Thermal Interface Material (TIM)
•CEK Spring
2.5.4.1 Geometric Envelope
The baseboard keepout zones on the primary and secondary sides and height
restrictions under the enabling component region are shown in detail in Appendix B.
The overall volumetric keep in zone encapsulates the processor, socket, and the entire
thermal/mechanical enabling solution.
