PWM values range from 0 (off) to 255 (full speed). Fan speed may be set to maximum when the temperature sensor associated with the PWM control exceeds temp#_max. +At Tmin - hysteresis the PWM output can either be off (0% duty cycle) or at the +minimum (i.e. auto_point1_pwm). This behaviour can be configured using the +pwm[1-*]_stall_disable sysfs attribute. A value of 0 means the fans will shut +off. A value of 1 means the fans will run at auto_point1_pwm. + Notes ----- |
