Thermal/Mechanical Reference Design 2 Thermal/Mechanical Reference Design This chapter describes the thermal/mechanical reference design for Quad-Core Intel® Xeon® Processor 5400 Series. Both Quad-Core Intel® Xeon® Processor X5400 Series and Quad-Core Intel® Xeon® Processor E5400 Series are targeted for the full range of form factors (2U, 2U+ and 1U). The Quad-Core Intel® Xeon® Processor X5482 sku is an ultra performance version of the Quad-Core Intel® Xeon® Processor 5400 Series with 150W

Thermal/Mechanical Reference Design The package includes an integrated heat spreader (IHS). The IHS transfers the non- uniform heat from the die to the top of the IHS, out of which the heat flux is more uniform and spreads over a larger surface area (not the entire IHS area). This allows more efficient heat transfer out of the package to an attached cooling device. The IHS is designed to be the interface for contacting a heatsink. Details can be found in the Quad-Core Intel® Xeon® Processor

Thermal/Mechanical Reference Design A potential mechanical solution for heavy heatsinks is the direct attachment of the heatsink to the chassis pan. In this case, the strength of the chassis pan can be utilized rather than solely relying on the baseboard strength. In addition to the general guidelines given above, contact with the baseboard surfaces should be minimized during installation in order to avoid any damage to the baseboard. The Intel reference design for Quad-Core Intel® Xeon® Pr

Please refer to the Quad-Core Intel® Xeon® Processor 5400 Series Datasheet for further details on TM and TM2. PROCHOT# is designed to assert at or a few degrees higher than maximum T (as CASE specified by the thermal profile) when dissipating TDP power, and can not be interpreted as an indication of processor case temperature. This temperature delta accounts fo
