pwmconfig: CPU fan no longer spins down

[Craig Hagerman]

Hi,

I have an Asus A8V Deluxe motherboard with Cool 'n' Quiet. Both the
cool and the quiet bit were working fine until recently. I had
installed lm-sensors, run pwmconfig etc (as per
http://ubuntuguide.org/wiki/Dapper). The CPU fan would be off most of
the time and everything was fine. Both of the (2) case fans were
connected to the power supply and not effected or controled by
pwmconfig.

Last weekend I bought a new case fan and attached it to the
motherboard connector. A while after I restarted I noticed that the
CPU fan was no longer spinning down. sensors reports that is is
spinning slower than full speed (could be, I can't be sure) but it
doesn't shut off. Sometimes sensors says that the CPU fan is off, but
it never is.

I reasoned that maybe the fancontrol or pwm or sensors.conf or
something related had to be reconfigured so I set everything up from
start again (as in the dapper guide above).

The problem is that pwmconfig no longer sets things up. It doesn't
spin down the CPU fan (nor the case fan) and doesn't seem to see it. I
shut down, disconnected the new fan from the motherboard, put
everythign back as it was and restarted. But pwmconfig STILL can't see
or spin down the CPU fan. I am getting very frustrated. Before my
machine was pretty quiet and I really want to get back to that level
at least. This has me pulling my hair out. I have shutdown and
restarted multiple times, and tried adjusting different settings (div
number on the fan for example) and nothing has any effect. Anyone else
have this kind of problem?

Craig

Found the following PWM controls:

   9191-0290/pwm2
   9191-0290/pwm3

Found the following fan sensors:
   9191-0290/fan1_input     current speed: 0 ... skipping!
   9191-0290/fan2_input     current speed: 3879 RPM

...
Testing pwm control 9191-0290/pwm2 ...
  9191-0290/fan2_input ... speed was 3879 now 3835
    no correlation

No correlations were detected.
There is either no fan connected to the output of 9191-0290/pwm2,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors.
