I am considering water cooling or some other form of quite cooling. I have a Antec P180 with 4800 Athlon. Temps of the CPU are rather high, but not too bad. My main concern is the fan on the GPU. All the other fans are pretty quiet. Use the Zalman 7700cu on the processor. I would like for the system to be quiter when under load. Especially the GPU fan. Thinking about water cooling the GPU and processor. I have plenty of room behind the desk for a radiator out of the system. What are the best components reguardless of price for cooling the CPU and GPU. Thought about leaving the case fans running because they are quiet. Chipset has heatsink, no fan. Board is Asus A8N-SLI Premium. Have system overclocked to 2640 mhz limited by cpu temp of 68 degrees under sustained load. Should be able to go higher with watercooling.
