Thank you, but I think it will not be enough: my other system is a
PowerMac11,2 (-> pm112) whereas I did the test on a PowerMac7,3.

I guess you should add also pm72, pm81, pm121, pm91.

According to C file comments, PowerMac7,3 is managed by pm72:
windfarm_pm72.c
/*
 * Windfarm PowerMac thermal control.
 * Control loops for PowerMac7,2 and 7,3
...
Regards,
Laurent
