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

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 
The overall volumetric keep in zone encapsulates the processor, socket, and the entire 
thermal/mechanical enabling solution.
