I'll tack this on here, seeing as there are two or three DCII 570 threads on the front page

Did that on 20 loops followed by 25 loops a couple minutes later with almost the same score. Perfectly stable, max temp was 58C, but it spent most of the time at 56C. Idle is at 37C. My fan profile has a 1:1 ratio from 45 to 60C with 45=45% too.
Just like to stress here, my case (Aerocool VX-R) isn't nearly a "good" airflow case, especially without the bottom intake fan mounted (insane dust with it mounted).
P.S. Smartdoctor is wholly inferior to Afterburner, shame that you can't adjust the DCII voltage in afterburner. That said, anyone know if there are issues using SmartDoctor to do the overclocking (voltage/core/memory) and then afterburner for fan control? Obviously I'd close afterburner anytime I made OC adjustments in Smartdoctor and Smartdoctor would have the fan set to "auto".
P.S.S. Holy **** watching the benchmark show a 3.5 million poly count at times. No wonder this game used to be impossible to run.
