I maybe wrong but AFAIK, 3-pin fans cannot be controller by ACPI (only
PWM, that is, 4-pin fans can). Anyway, you can use an external fan
regulator which allows you to put the fan rpm at fixed speed or you can
buy a silent (low speed) fan.

I think ACPI can cotrol 3-pin fans too -- *if* such support is built
into the motherboard. You probably just have to install some particular
package, such as lm-sensors or fancontrol or a dedicated kernel module?
I regret not being able to be more specific, but it's been some time
since I've tackled the fan controllers on my boxes. I was under the
impression actually that ACPI fan control worked out-of-the-box on
Debian, but memory may be failing me (and I don't mean RAM).

I think fans can be /sensed/, i.e. RPM, but not /regulated/. Three pin
fans are +12v, ground, and sense. (Or is it +5v? Anyway...)

Hmm, I had an Asus motherboard that had 4 fan connectors on the
motherboard, all 3 pin. And it could regulate 2 of the 4 fans.

All right. So it depends on the MB. What about OP's MB?

I guess that's for him to find out? Reading the user -- or service &
maintenance -- guide would be a good first step IMHO. Unless some list
member has hands-on experience with that particular MB and can confirm
whether fan control is implemented or not.

lm_sensors provides that ability _but_ I think you still need 4-pin fans
or you can get undesired results:

http://www.lm-sensors.org/wiki/man/fancontrol

What I use is a "fixed" regulator (external) for controlling the micro
fan speed. Dunno if "fancontrol" can also do it that way :-?

I avoid using PWM fans, for computer case or heatsink. I prefer to stick
with 3-pin and manually control them to get a silent PC. In fact, most of
the fans in the case are unregulated but of those called "quiet" (min.18/
max.25dB) so I don't have to bother about them.

It would seem that the fancontrol package is meant for manually
tweaking the fans -- something I wouldn't reccommend and something I
don't use myself. As already stated on this list a while ago, fan
control (just as thermal shutdown) is best left to the hardware. Trying
to override it with user settings may lead to unwanted results.

You're right about the fancontrol package -- according to its manpage,
it apparently only deals with pwm fans. Many "el cheapo" fans are
voltage-regulated though, and IME many motherboards with 3-pin headers
have provisions for regulating the voltage (and, consequently, the fan
speed) of at least some of those headers. That said, without the
motherboard's manual, our guesswork can only be academic.

Howdy!

I'm a bit late with answer, but had to go to work.
The case is el cheapo and had slim fan without any control. I got
new, but that one was "fat" and I had to change the place for it.
The whole case and components are never hot, even warm. During
stream session the server is not in the sight or at ear distance
to make annoyance. It is only a matter of proving it might be
better.
The very box is not my first choice and comes as "make it cheap
as possible". Another variant was:
www.fit-pc.com/web/
This small box is not easy to find and is expensive compared to
atom node. Anyway, since the server fulfills it's job, I'm sure
I will keep it on the hidden place and have it up when needed,
not 24/7 as I'd use fit-pc.
Thank you all for respond and insight at acpi for atom.
Best regards

Zoran

Actually it was an Abit AX8.
