Hello, I was wondering, do GPUs usually reach 80%-100% fan speed while playing games for a long time at high settings? I want to buy a GTX 465 and unlock it if possible (if it has the chips) into a GTX 470 (I know Gtx 460 is better than a gtx 465 in many ways) but on a video I saw gtx 465 at 80%-100% fan speed it makes a very loud noise on its reference cooler.
