Been messing about with custom fan settings for my 470's, set a profile in afterburner of 65% fan speed at 70c, temps at 66-64c ono in game, (bfbc2). 70-66c in heaven. They normally top out at 80-77c ono on auto fan setting. Noise is actually pretty mild, not a problem at all when gaming as i wear noise cancelling headphones. Am i right in thinking that auto fan should also be enabled in afterburner as well as the user defined setting. Cards are clocked at 751/1502/1674 on stock voltage of 0.987.
