To be able to control your fan and do more sophisticated stuff we need to set some parameters on load time of the module.
Set the following content in the file

# cat fan status: enabled speed: 3051 level: 5 commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))

# echo "level full-speed" > fan
