Next Step...?
Who knows, I guess the next logical step for adding to this system would be a reservoir to increase the water capacity of the system which would help maintain a lower residual water temperature.
What's next for me? Well I'd like to take a look at a phase cooling system, but I'll be saving pennies for a while to get there. That's the great advantage with WaterCooling, it has two prongs to it's appeal. One is you can run quietly, or on the other hand you can strap a huge radiator and lots of fans to it and get nearer room temperature for your CPU.
