  - 'fancontrol-ng' is a clone of fancontrol that can handle errors on resume
    from suspend instead of setting fans to maximum speed and quitting;
    in general it doesn't handle everything the original does

+   and nmcli that are painfully lacking it
 
 Don't expect them to work under any OS that isn't Linux.
