I know the Q-Fan works. But I wanted exactly the ability to control
it from software (a-la fanspeed).  Here, due to the way my machine
is built, the fan isn't needed most of the time (there's a large
air duct inside that covers large CPU heatsink, hdd, northbridge
heatsink and the PSU, that gets use of natural airflow), but it's
used when the temperature grows.  So that most of the time, the
system is 100% quiet, and only when I run something that uses much
power it starts heating slowly, until a fan gets turned on.  That
to say, the built-in q-fan profile isn't sufficient ;)  And yes,
I'm such a crazy fan-noise-hater, and all the components of this
system are choosen to satisfy this my craziness, including many
parts that I made myself (airduct, noise-dampering matherials
inside the case, fan mounting and placement and so on).

Oh, so it's basically boils down to Silent/Optimal/Normal choices
as in the BIOS settings, right?  I mean, still no pwm_* controls
as it87 offers?..

Thanks!
