Thermal/Mechanical Reference Design

2.5.4Assembly 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

2.5.4.1Geometric 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.
