Thermal Specifications and Design Considerations

Datasheet
Note:
Intel recommends both Intel Thermal Monitors be enabled.
When PROCHOT# is driven by an external agent, if only TM1 is enabled on both cores,
then both processor cores will have their core clocks modulated. If TM2 is enabled on
both cores, then both processor core will enter the lowest programmed TM2
performance state.
One application is the thermal protection of voltage regulators (VR). System designers
can create a circuit to monitor the VR temperature and activate the TCC when the
temperature limit of the VR is reached. By asserting PROCHOT# (pulled-low) and
activating the TCC, the VR can cool down as a result of reduced processor power
consumption. Bi-directional PROCHOT# can allow VR thermal designs to target
maximum sustained current instead of maximum current. Systems should still provide
proper cooling for the VR, and rely on bi-directional PROCHOT# only as a backup in
case of system cooling failure. The system thermal design should allow the power
delivery circuitry to operate within its temperature specification even while the
processor is operating at its TDP. With a properly designed and characterized thermal
solution, it is anticipated that bi-directional PROCHOT# would only be asserted for very
short periods of time when running the most power intensive applications. An under-
designed thermal solution that is not able to prevent excessive assertion of PROCHOT#
in the anticipated ambient environment may cause a noticeable performance loss.
