Thermal Specifications and Design Considerations
The EP80579 requires a thermal solution that maintains the maximum case
temperature defined in Table 50-1, “EP80579 Thermal Design Power (TDP) and
Maximum Case Temperature Specifications (TC-MAX)” . Any attempt to operate outside
these operating limits may result in permanent damage to the processor and
potentially other components in the system. As processor technology changes, thermal
management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable long-term system
operation. A complete thermal solution includes both component-level and system-
level thermal management features. Refer to the Intel^® EP80579 Integrated Processor
product line Thermal Design Guide for a thorough treatment of thermal design
considerations.
To allow for the optimal operation and long-term reliability of Intel^® architecture-based
systems, the system/processor thermal solution must be designed such that the
processor remains within the minimum and maximum case temperature (T_C-MAX)
specifications at the corresponding Thermal Design Power (TDP) value listed in
Table 50-1. Thermal solutions that are not designed to provide this level of thermal
capability may affect the long-term reliability of the processor and the system. The
case temperature is defined at the geometric top center of the Integrated Heat
Spreader (IHS).
The EP80579 monitors die temperature using athermal sensor.The thermal sensor
(described in Section 50.2, “Thermal Sensor”) must be used to determine when the
maximum specified component temperature has been reached. The on-die thermal
sensor is designed 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 50.2, “Thermal Sensor”. In all
cases, the thermal sensor feature must be enabled for the processor to remain within
the operating limits.
