View Full Version : Trying to get fancontrol working

Hello,

I've just recently had some success at getting the "cpuspeed" module and demon setup and running, and have got my CPU stepping up and down (depending on the activity) between 1GHz and 2.2. So all is well in that department.

But, I am having some trouble getting the fans to behave. My system is an AMD Athlon 64 3500+ (Socket 939) CPU on an ASUS A8V (Vanilla) board.

When I run "pwmconfig" it gives me the following (rather bizarre) output. I would greatly appreciate any help you guys can offer so I can enjoy some peace and quiet with these fans!! I've no real idea about what the heck a pwm output is, but I would assume that the default fans shipped with my CPU would have the right connections ???

[root@localhost ~]# pwmconfig
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following PWM controls:
9191-0290/pwm1
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: 2327 RPM
9191-0290/fan3_input current speed: 2070 RPM

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!
Hit return to continue:

Testing pwm control 9191-0290/pwm1 ...

No correlations were detected.
There is either no fan connected to the output of 9191-0290/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)

Did you see/hear a fan stopping during the above test (n)?

Testing is complete.
Please verify that all fans have returned to their normal speed.

The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? n

By the way, I should add that I am using Fedora Core 4, kernel 2.6.15-1.1833_FC4
