"PROCHOT# and THERMTRIP#
Processors assert PROCHOT# when activating a thermal control
circuit that can automatically throttle processor clock speed.
When the junction temperature exceeds a critical threshold, the
processor asserts THERMTRIP#. Upon a THERMTRIP# trigger,
Intel processors attempt to stop internal clocks and halt program
execution to reduce internal temperature and avoid processor
damage"
I get that THERMTRIP is based on a "junction" temperature and PROCHOT is clearly activated by the sensor reading near the ALU from previous readings.
