Thermal Specifications and
Design Considerations
The processor requires a thermal solution to maintain temperatures within operating
limits as set forth in Section Thermal Specifications. Any attempt to operate the
processor 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.

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 and system level thermal
management features. Component level thermal solutions include active or passive
heatsink attached to the exposed processor die. The solution should make firm contact
to the die while maintaining processor mechanical specifications such as pressure. A
typical system level thermal solution may consist of a system fan used to evacuate or
pull air through the system. Alternatively, the processor may be in a fan-less system,
but would likely still use a multi-component heat spreader. Note that trading of thermal
solutions also involves trading performance.

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 within the minimum and maximum junction temperature (Tj)
specifications at the corresponding thermal design power (TDP) value listed in
systems, the system/processor thermal solution should be designed such that the
processor remains within the minimum and maximum junction temperature (Tj)
specifications at the corresponding thermal design power (TDP) value listed in
. Thermal solutions not designed to provide this level of thermal capability may affect
the long-term reliability of the processor and system.
The maximum junction temperature is defined by an activation of the processor
Thermal Monitor. Refer to
Thermal Monitor. Refer to
for more details. Analysis indicates that real
applications are unlikely to cause the processor to consume the theoretical maximum
power dissipation for sustained time periods. Intel recommends that complete thermal
solution designs target the TDP indicated in
power dissipation for sustained time periods. Intel recommends that complete thermal
solution designs target the TDP indicated in
instead of the maximum
processor power consumption. The Intel Thermal Monitor feature 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
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
. In all cases the Intel Thermal Monitor feature
must be enabled for the processor to remain within specification.
