1U Alternative Heatsink Thermal/Mechanical Design
x = Processor power value (W)
Figure A-3 below shows the comparison of this reference thermal solution’s Thermal
Profile to the Quad-Core Intel® Xeon® Processor E5400 Series Thermal Profile
specification. The 1U alternative solution meets the Thermal Profile with 0.5°C margin
at the upper end (TDP). By designing to Thermal Profile, it is ensured that no
measurable performance loss due to TCC activation is observed under the given
environmental conditions.
