I have two rigs mining but this is my main one:
Two 5870's. One is overclocked at 1120/500 → 469 MHash/s. The other has a minimal overclock (900/600) → 376 MHash/s.
Serious question: Why do you have so much radiator surface area? Do you need that much area to dump the heat? Is your water temperature running near ambient temps? Did you have to add more radiators because your delta was getting too large? I ask because back in the day when I designed my own water cooling system (before you could buy them in a box) I was able to get away with a radiator about 250mm x 120mm.Two 5870's.
