Power specifications are defined at all VID values found in Table 7 -3 . The processor
may be delivered under multiple VIDs for each frequency. Implementation of a
specified thermal profile should result in virtually no TCC activation. Failure to comply
with the specified thermal profile will result in increased probability of TCC activation
and may incur measurable performance loss. Refer to the
Intel® Xeon® Processor
E5-1600 v2/E5-2600 v2/E5-4600 v2 Product Families Thermal/Mechanical Design
Guide for system and environmental implementation details.
Each case temperature thermal profile is unique to each TDP and core count
combination. These T
CASE
profiles are fully defined by the simple linear equation:
T
CASE
= PSI
CA
* P + T
LA
Where:
PSI
CA
is the Case-to-Ambient thermal resistance of the processor thermal solution.
T
LA
is the Local Ambient nominal temperature.
P is the processor power dissipation.
The Short-Term thermal profile provides for a 15°C rise of temperature above the
nominal profile due to scenarios such as fan failure or A/C failure. Short-term
excursions to higher ambient operating temperatures are strictly limited 96 hours per
instance, 360 hours per year, and a maximum of 15 instances per year as intended by
NEBS Level 3.
T
LA-ST
designates the Local Ambient temperature for Short-Term operation.
Ta b l e 5 - 3 provides the
PSI
CA
and T
LA
parameters that define T
CASE
thermal profile for
each TDP/Core count combination. Figure 5-3 illustrates the general form of the
resulting linear graph resulting from
T
CASE
= PSI
CA
* P + T
LA
.
