You can use custom labels and ignore inputs without setting this option if
you can figure out their names (see which `*_label` contains builtin label).
## CONFIGURATION VIA SYSFS
### `pwm[1-8]`
Gets/sets PWM duty cycle or DC value that defines fan speed. Which unit is used
depends on what was configured by firmware.
Accepted values: `0`-`255` (slowest to full speed).
Writing to this file changes fan control to manual mode.
Example:
```
# slow down a fan as much as possible (will stop it if the fan supports zero RPM mode)
echo 0 > pwm6
# fix a fan at around half its speed (actual behaviour depends on the fan)
echo 128 > pwm6
# full speed
echo 255 > pwm6
```
