The folks at Nuvoton are actually quite nice and sent me a copy.
I browsed through it, specifically the fan control section, but I don't see
what might be different to the current implementation. Of course it would help
to have a copy of the W83667HG datasheet to be able to compare .. I'll see
if I can get that one as well.
