1U Alternative Heatsink
Thermal/Mechanical Design
Intel has also developed an 1U alternative reference heatsink design for the
volumetrically constrained form factor and targeted for the rack-optimized and ultra
dense SKUs. This alternative heatsink design meets the thermal profile specifications of
the Quad-Core Intel® Xeon® Processor E5400 Series and offers the advantages of
weight reduction and cost savings in using this alternative 1U heatsink.

Component Overview
The alternative 1U reference heatsink is an extruded aluminum heatsink and shares the
same volumetric footprint as the 1U CEK heatsink. It reuses Intel 1U CEK Captive
standoff/screws, Thermal Interface Material (TIM) and Spring.
