Thermal Specifications and Design Considerations
temperature within the 100°C (maximum) specification. If the platform thermal
solution is not able to maintain the processor junction temperature within the
maximum specification, the system must initiate an orderly shutdown to prevent
damage. If the processor enters one of the above low power states with PROCHOT#
already asserted, PROCHOT# will remain asserted until the processor exits the Low
Power state and the processor junction temperature drops below the thermal trip point.
If automatic mode is disabled, the processor will be operating out of specification.
Regardless of enabling the automatic or On-Demand modes, in the event of a
catastrophic cooling failure, the processor will automatically shut down when the silicon
has reached a temperature of approximately 125°C. At this point the FSB signal
THERMTRIP# will go active. THERMTRIP# activation is independent of processor
activity and does not generate any bus cycles. When THERMTRIP# is asserted, the
processor core voltage must be shut down within a time specified in Chapter 3.
