i've tried rivatuner - and i doesn't make that same noise as atitool does. but there are limited fan options in rivatuner, so i cant control the fan as much as i'd like.
i've checked "Do not change PWM base frequency" thing aswell. Nothing seems to get rid of the noise other than uninstalling atitool, or stopping the fan. any ideas?
Edit: don't know if it matters but, Im using cataclyst 5.6
