Thermal Metrology
The minimum and maximum case temperatures (T
CASE
) are specified in
Table 6-2
,
Table 6-4
,
Table 6-5
, and
Table 6-7
, and
Table 6-9
and
Table 6-11
are measured at the
geometric top center of the processor integrated heat spreader (IHS).
Figure 6-6
illustrates the location where T

temperature measurements should be made. For
detailed guidelines on temperature measurement methodology, refer to the Quad-Core
Intel® Xeon® Processor 5400 Series Thermal/Mechanical Design Guidelines (TMDG).

Thermal Monitor Features
Quad-Core Intel® Xeon® Processor 5400 Series provides two thermal monitor
features, Intel® Thermal Monitor 1 and Intel® Thermal Monitor 2. The Intel® Thermal
Monitor 1 and Intel® Thermal Monitor 2 must both be enabled in BIOS for the
processor to be operating within specifications. When both are enabled, Intel® Thermal
Monitor 2 will be activated first and Intel® Thermal Monitor 1 will be added if Intel®
Thermal Monitor 2 is not effective.
6.2.1.1
Intel® Thermal Monitor 1
The Intel® Thermal Monitor 1 feature helps control the processor temperature by
activating the Thermal Control Circuit (TCC) when the processor silicon reaches its
maximum operating temperature. The TCC reduces processor power consumption as
