Looking good!! What kind of temps are you looking at on load? Very curious about setups with the GPU temp pumping heat into the CPU; unless you have yours set up in reverse (CPU -> GPU). Somewhat hard to tell the flow.
Loop goes Pump-Gpu-Cpu-240rad-240rad-res-pump.
Under full artificial load (cpu, fpu, cache, gpu, ram) all at 100%, the CPU package levels out at about 68C and the GPU at about 48C (but very slowly creeps up due to cpu temp heating the water). I can run this almost infinitely.
That said, this is w/ cpu @ 3.85GHz, VGA at 2114 core and about 10,900MHz on yhe memory (iirc. Not home now).
Simply gaming/streaming, etc. The CPU package and GPU rarely ever exceeds 44C
