Ok. Thanks. I will CC.

No. This isn't the same problem I have. He uses the 4-pin connector. I
only use two case fans on normal 3-pin connectors which are controllable
by Speedfan under Windows.

Good point. I'm so stupid. I do a sudo echo "0" > pwm1. So echo "0" is
executed as root but the file writing not. Ok as root it works. I can
write something into actually pwm4 and the fan stops.
But pwmconfig does not work either. It says:
------------------------------------------------------------
Found the following PWM controls:
hwmon0/device/pwm1
hwmon0/device/pwm1_enable stuck to 1
Failed to set pwmhwmon0/device/pwm1 to full speed
Something's wrong, check your fans!
------------------------------------------------------------
And if I try a echo "0" > pwm1_enable I get "bash: echo: write error:
Invalid argument". echo "2" works. So I think this is one for you.
Best Regards and thanks for help
Alex
