The 9600 Pro core runs very cool at stock cooling. Why would you want to invest such $ on an already cool running core? If you want to eek the last mhz out of the 9600 core why not try a better HSF unit first?
Well my original idea was as little fans/noise as possible. I didnt however know that it ran cool in stock form. I'm just looking to max it out and figured I'd go ahead and throw water on it. How high have people got it on air cooling?
I think theres one made by Vantec called the Iceburg. Google search it at Vantec's sight. I've read good reviews about it and I believe SVC sells it. If you don't believe me about the 9600 Pro running cool, stick your finger behind the GPU after palying a strenuous game. On some of the older Nvidia cards this was an invitation to scorch one's finger. On your ATI card you'll be quite pleased with the results.
