Thermal Specifications
power at which T_CASE, calculated from the thermal profile, corresponds to the lowest possible
value of Tcontrol. This point is associated with the Tcontrol value (see Section 7.2.7). However,
because Tcontrol represents a diode temperature, it is necessary to define the associated case
temperature. This is T_{CASE_MAX} @ P_{CONTROL_BASE}. Please see Section 7.2.7 and the Processor
Thermal/Mechanical Design Guidelines for proper usage of the Tcontrol specification.
The case temperature is defined at the geometric top center of the processor IHS. Analysis
indicates that real applications are unlikely to cause the processor to consume maximum power
dissipation for sustained time periods. Intel recommends that complete thermal solution designs
target the TDP indicated in Table 7-1, instead of the maximum processor power consumption. The
Thermal Monitor feature is intended to help protect the processor in the event that an application
exceeds the TDP recommendation for a sustained time period. For more details on this feature,
refer to Section 7.2. To ensure maximum flexibility for future requirements, systems should be
designed to the Flexible Motherboard (FMB) guidelines, even if a processor with a lower thermal
dissipation is currently planned. Thermal Monitor or Thermal Monitor 2 feature must be
enabled for the processor to remain within specification.

NOTE:
1. Thermal Design Power (TDP) should be used for processor thermal solution design targets. The TDP is not
the maximum power that the processor can dissipate. TDP is measured at maximum T_CASE.
2. FMB, or Flexible Motherboard, guidelines provide a design target for meeting future thermal requirements.
See Section 2.10.1 for further information on FMB.
3. Maximum Power is the maximum thermal power that can be dissipated by the processor through the
integrated heat spreader. Maximum Power is measured at maximum T_CASE.
