I have had good results with a couple of copper coolers. One is made by Galaxy, the gnx80 I think. Also the Thermaltake volcano 10+ did really well. I haven't been pleased at all with stock coolers, orbs or coolermaster. My next AMD cooler for my 2500 barton will be the SLK 900a with a Panaflo 92 mm fan and an adjustable fan speed controller. LIke you, I'm looking for quiet. My volcano 9 ain't it!!
