Which brings us back to the original challenge.

Can a waterblock at low-flow rates (~1-1.5LPM), as would be typical of a system coupled with 6-7mm or ¼" ID tubing, and, using with a low-powered quiet pump (<1.5mH2O peak pressure, <10LPM peak flow) provide block-level performance that is within 0.02C/W of a 6+LPM flow rate system, as is typical of a ½" ID system when using a well powered pump (>3.0mH2O peak pressure, >10LPM peak flow rate).

Well, at least that is what I'd like to see proven before I would start to hold any weight in these "engineering vs brute-force" arguments.

Of course I would still stick a strong pump and at least 3/8" ID tubing on the "low flow" system just to remove those artificial limitations and perhaps get back that lost 0.02C/W, but that is just my personal focus.

This is all tangential to my own waterblock work though. I personally sit in the middle of the argument in belief, although I do chase bleeding edge overclocks for fun.
