Nowhere does it state that the user visible diode is the one that control THERMTRIP. If it was, then the XBitLabs THERMTRIP test would've shutdown at 135C, rather than the indicated 94C.

Which is the same as I always have been saying about the user visible diode: "Numb and Dumb" - it doesn't reflect the actual peak CPU temperature.

A third diode perhaps? Or perhaps, and more likely, a second thermal trip sensor (ie. THERMTRIP) calibrated to 135C and driven by the same thermal diode that drives the PROCHOT trip sensor, which in turn drives the Control Circuit.
