The desired fan speeds (or PWM duty cycles) are written -through the I2C interface. The outputs drive "4-wire" fans directly, -or can be used to modulate the fan's power terminals using an external -pass transistor. - -Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%) -monitoring and control of fan RPM as well as detection of fan failure. -Six pins are dedicated tachometer inputs. Any of the six PWM outputs can -also be configured to serve as tachometer inputs. - - -Sysfs entries -------------- - -fan[1-12]_input RO fan tachometer speed in RPM -fan[1-12]_fault RO fan experienced fault -fan[1-6]_target RW desired fan speed in RPM -pwm[1-6]_enable RW regulator mode, 0=disabled, 1=manual mode, 2=rpm mode -pwm[1-6] RW fan target duty cycle (0-255) |
