So it clearly appears that the fan in disengaged mode can't keep the CPU under the first thermal trip level of 75 degrees C.

1. In this scenario, the first thermal trip level is basically saying "start using passive cooling strategies to keep CPU cool". This implies throttling back the CPU, for example CPU freq scaling or P-state limiting.

2. This *clearly* indicates that something is broken at the hardware level as I have pointed out numerous times.

Summary:

Even with fan running in disengaged mode the fan cannot get the machine below the passive trip zone level.
Hardware is clearly broken.
Not a software fix issue.
Won't Fix.
