Thermal Specifications
To allow for the optimal operation and long-term reliability of Intel processor-based systems, the
system/processor thermal solution should be designed such that the processor remains between the
minimum and maximum case temperature (TC) specifications when operating at or below the
Thermal Design Power (TDP) value listed per frequency in Table 42. Thermal solutions not
designed to provide this level of thermal capability may affect the long-term reliability of the
processor and system. For more details on thermal solution design, please refer to the appropriate
processor thermal design guidelines.
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 periods of time. Intel recommends that complete thermal solution designs
target the Thermal Design Power (TDP) indicated in Table 42 instead of the maximum processor
power consumption. The Thermal Monitor feature is intended to help protect the processor in the
unlikely event that an application exceeds the TDP recommendation for a sustained period of time.
For more details on the usage of this feature, refer to Section 6.3. To ensure maximum flexibility
for future requirements, systems should be designed to the Flexible Motherboard Guidelines
(FMB), even if a processor with a lower thermal dissipation is currently planned. In all cases, the
Thermal Monitor feature must be enabled for the processor to remain within specification
NOTE:
1. Intel recommends that thermal solutions be designed utilizing the Thermal Design Power values. Refer to the
Intel Xeon Processor Thermal Design Guidelines
.
2. TDP values are specified at the point on Vcc_max loadline corresponding to Icc_TDP.
3. Systems must be designed to ensure that the processor is not subjected to any static Vcc and Icc
combination wherein Vcc exceeds Vcc_max at specified Icc. Please refer to the loadline specifications in
Chapter 2.0.
