Support for the hwmon > class was added relatively recently (2.10.2). Thanks. I used 2.10.0. After installing lm-sensors 2.10.4 without modifying my driver, run pwmconfig, the result is: Found the following devices: hwmon0/device is w83l786ng 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! Did I miss something? Why it can't detect my fans? Thank you. > -- > Jean Delvare > BR, Dave.
