Hello,
I use lm-sensors version 2.9.2-5ubuntu3 (I am on the last stable Ubunutu 6.06).
My chipset is a Winbond W83697HF and my mobo is a MSI K8T Neo-FIS2R (MS-6702).
I have the same problem :
Testing pwm control 9191-0290/pwm1 ...
9191-0290/fan1_input ... speed was 2636 now 0
It appears that fan 9191-0290/fan1_input
is controlled by pwm 9191-0290/pwm1
Would you like to generate a detailed correlation (y)?
Would you like to generate a graphical plot using gnuplot (y)?
PWM 255 FAN 2678
PWM 245 FAN 2596
PWM 235 FAN 2596
PWM 225 FAN 2596
PWM 215 FAN 2636
PWM 205 FAN 2596
[...]
PWM 65 FAN 2636
PWM 55 FAN 2556
PWM 45 FAN 2556
PWM 35 FAN 2596
PWM 25 FAN 2556
PWM 15 FAN 2556
PWM 5 FAN 2518
Hit return to continue...
However, I'm sure the fan is controllable in speed because under Windows (only
:( ), MSI provides a software (CoreCenter) that works perfectly (in "thermal"
or "speed cruise", speed regulated between 1500 and 2600 rpm). Still under
windows XP, I tested SpeedFan and I had the same problem than with pwmconfig.
The only way I succeeded in reducing the speed was to low the clock of PWM
clock frequency, which you propose.
I am relatively a beginner with linux (for 4 months only). Can fancontrol use
the pwm clock frequency to regulate fan speed ? Or could you explain how to do
what you propose ?
It seems to me that Ticket #1419 talks about this parameter PWMCLK but I didn't
see it in sensors.conf.
I didn't know if I had to respond to you or to the mailing-list, excuse me I am
mistaken.
Thanks for your help,
