In my experience, it is THM2 which triggers the fan under normal use
conditions, not THM0. Some kernels (e.g. 2.6.11rc4) do not let the fan go off
when THM2/trip_points is reached, hence your experience. Check that point,
because otherwise your motherboard might suffer a bit !

it does work provided that the linked patch has been applied. Alternatively, I
have attached a patched rsparser.c (it should replace
drivers/pnp/pnpacpi/rsparser.c)
Note that in fact with acpi. the sound card must be activated irrespective of
whether quick boot is enabled.
Thanks for the infos
