Mine does 960's with Alpha, previously 930's with fan included with Duron. Really wanted to get to 1GHz, but refuses to let me get that high. Voltage is upped to 1.85v. Temperature is usually around the 45-50 range, 48-54 range during hot days. I have one intake, one outtake 80 mm fan for case, Antec KS282 along with Abit KT7-RAID.
