I remember those too, mine was on a T-bird with zalman heatsink with the delta 60mm fan 7K+ rpm, damn jet engine!That's what I'm hoping for.. I had an Opteron 165 (1.8Ghz) which I believe I was able to overclock to around 2.8Ghz or just under. I was using one of those jet engine sounding coolers though, with a Delta 60mm (7000rpm) fan I think... No fan curves, just full throttle all the timeObscenely loud.
