Yeah, cnu had told me to do that in another thread. It was the only way I could Riva to let me access anything.
I DO have crazy fan-age right now (5 Antec TRICOOL on high)... although I doubt that would account for 30+C change...
Well, I wouldn't worry too much. Just set your fan speed to at least 75%, then OC away.
Talking about fan crazy, I have 9 x 120mm fans in my case.
