At this point the Zalman CNPS9500 bowed out. It was able to prime the Opteron 146 up to 2.90 Ghz but was unable to maintain prime stability any further while using the CNPS9500 - consider this that it was a closed case environment. We've seen results showing the Zalman CNPS9500 excelling on an open bench, I don't consider an open bench environment a computer - it needs to be in a closed case for me to really accept cooling figures..
