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.
