    I haven’t upgraded my Quad yet to 3.16 but I might try running it off the update first and see how the fans behave.

    I tried MOS 3.15 and 3.14 booted from USB and all is the same - fans stays on low RPM, while CPU temp rises above 70°C.

    According to cyfm, Mac Mini fans are controlled with uPMU controller automatically, without management from MorphOS.
    When I see Powermac G5 diagram, it looks like the fans are controlled via SMU (System Management Unit).
    Are MorphOS involved here with control or not and all is automatic ?

    And is it useful to reset the SMU?

    Because temperature regulation for me now works with MacOSX and not works with MorphOS. And worked for me with MorphOS a year before or so.
    It is strange.
