           Specifies the fan we want to use.
           On anything other than a Thinkpad you'll probably
           use some PWM control file in /sys/class/hwmon.
-          Remember that fan levels range from 0 to 255 and that
-          they're just a number, not including the word "level"
-          as seen below.
           A sysfs fan would be specified like this:
             pwm_fan /sys/class/hwmon/hwmon2/device/pwm1
