You guys have sparked my interest with these ideas
I could simply use a "T" for distributing the flow from the pump to the radiators, using the perpendicular fitting for the GPU-line as the flow along that fitting will be more restricted.
Then I add another fitting to the air-trap so I have another incoming line.. seems like little work
About my temperatures, when I run my CPU at default (1333@1.75), I idle at 14-16 degrees (Celcius) above ambient, which I don't find that bad. The problem is that I'm very close to the point where my current radiator runs out of steam - it can't dissipate much more heat without raising the water temperature significantly..
