The more charts I see the more sense it makes to me (again I could be wrong) that we use a common rad and fans. This will also have the effect of eliminating noise levels from the debate...

Well by now it should be clear that if you reduce restrictions (which WILL increase flow) that radiator and waterblock performance WILL improve. Now the magnitude of that improvement is going to depend greatly on the parts that you are using in the total kit.
The original question (and still the most interesting one imo) is whether one can design a kit with 6mm tubing and quiet, low pressure pumps that cools NEARLY as well as one with larger tubing and higher pressure pumps. That is what has been claimed by many of the Europeans in essense, right? You said yourself earlier that you were only a degree or two off from the highest performance. Now there are a few ways your statement could be true:
1) It could be that the radiator you are using is so much more effective that your water temperatures are much closer to room temperature than with the radiators the "high flow guys" use.
2) It could be that the waterblocks you are using are so much more effective than "high flow" offerings that your CPU stays closer to water temp at 1-1.5LPM with that block than a "high flow" wb can achieve even at 8-10LPM.
3) "1-2C off from Best performance" could merely be referring to "with the same waterblocks and radiators" and not referring to "with any available watercooling parts". This could well be true; there is not more than a degree or so difference in the Innovatek Rev3 at 0.5GPM and at 2GPM; one would expect blocks destined for 6mm tubing loops to have thick baseplates and not respond especially well to raising flow rates.
I think testing the complete kits is a far more interesting approach to getting at how tradeoffs made in the name of convenience and noise affect performance.
Is it also reasonable for me to test my own personal cooling loop first off? It's nothing special really (FedCo 2-342, Laing D4, 2 Panaflo M1As, 1/2" Clearflex, LR Cascade). It is plumbed properly though and is IMO a pretty good example of what performance is possible if one has an eye to limiting flow resistance everywhere except the wb (where it's very useful).

you should delist the first rad article and sub the ThermoChill review.

No way I am delisting OCers article 481. That treatise (though it DESPERATELY needs the revised graphs) completely changed the way I thought about wcing and testing and put several observations I had already made in my piddling into the proper scientific context. If it weren't for that article I'd probably be...
more productive at work?
more connected with wife?
hmm left-handed compliments taste the bestest I am told
