I tried clocking it up to those settings with ATI Tray Tools, and the fan suddently went from silent to loud as hell, and then my system froze and my monitors turned off, so I quickly hit the reset button. What the heck is going on here? I've also noticed that during the 3DMark06 tests, the fan never makes any noise, so I'd assume that it's not clocking the speeds up only during active 3d rendering.
