Thermal/Mechanical Reference Design
The 2U+ CEK Intel reference thermal solution is designed to meet the Thermal Profile A
for the Dual-Core Intel Xeon Processor 5160. From Table 2-6, the three-sigma
(mean+3sigma) performance of the thermal solution is computed to be 0.236°C/W and
the processor local ambient temperature (T
LA
) for this thermal solution is 40°C. Hence,
the Thermal Profile equation for this thermal solution is calculated as:
Equation 2-10.y = 0.236x + 40
where,
y = Processor T
CASE
value (°C)
x = Processor power value (W)
Figure 2-19 below shows the comparison of this reference thermal solution’s Thermal
Profile to the Dual-Core Intel
®
Xeon
®
Processor 5160 Thermal Profile A specification.
The 2U+ CEK solution meets the Thermal Profile A with a 1.3°C margin at the lower
end (P
_PROFILE_MIN
) and 1.1°C margin at the upper end (TDP). By designing to Thermal
Profile A, it is ensured that no measurable performance loss due to TCC activation is
observed under the given environmental conditions.
