ok, so if I had to rebuild this rig from scratch I would use 2 X 480mm radiators, instead of the 360mm radiators that I did use. the reason that I would use 480mm radiators is because, 2 X 480mm radiators is enough space to cool a CPU, and video card, while overclocked, and under a heavy load. while a system with 2 X 360mm radiators on it, if the system is overclocked, and under a heavy load, the water will heat up. so, for me the ideal conditions on a water loop, is being able to have a 1C to 2C delta T, while the system is under a heavy load. this system when finished, will be able to do that, as long as I do not overclock any of the hardware.
