I tried ati tray tool a long time ago and remember not liking it that much. with my x800gto ati tool overclocked great and set the fan like I wanted. I just tried ati tool .27c and the fan control and monitoing is all over the place. It said my fan was 0% much of the time which I doubt or at least hope it wasn't.
Anyway, I have a 790fx board coming and will try AMD overdrive and see what happens. thanks
