Most Asus mobos have Q-FAN settings in the BIOS screen; you can use automatic management to let the hardware control the fan, the driver does not interfere with that (and if it does then it's a bug). > Ok.

In term of Q-FAN profiles: yes, but I still haven't managed to make it work (the interface is there though).
