Not entirely.
If I rename w83627hf.ko to something else and reboot, the fans stop.
Then I rename w83627hf.ko back to its original name and do modprobe
(without stuff in modprobe.conf) and the fans stay still.
I rmmod w83627hf and then try with the reset=1 parameter.
Only then the fans start spinning.

Depending on the cause, yes.
See my description, also without the w83627hf driver the fans stop. (!?)

Is it part of fedora startup scripts? I will do a grep.

2.6.18.1, self compiled. I can mail you my config.

Not that I am aware. I only enabled sensors drivers for historical
reasons or for this new board.

Will try that later.
