just incase someone has problems turning off cool & quiet. if it wont turn off after you turn it off in the BIOS. if your overclocking with asus AI booster. on Ai booster clic on display tuning panel and there is a button on the right side that says enable Qfan that gets enabled when you turn on cool & quiet and even if you disable C&Q in the BIOS it doesn't always turn this button off. hope this is understandable & helps someone..
