Guess I could have worded that better. But my own impression from reading at a number of eu sites is that many are more interested in noise reduction that O/C. "MANY" not all. And prehaps my impression is wrong at that. The tidy case point that Gerwin made is a good one, and one I hadn't given much thought to.
As to larger pumps. When multiple blocks & or pelts are involved I do think they can lower temps. But would be interested in reading the results of that mans tests if you could post a link & it's in english. A even those like myself, who like the larger pumps have to admit that they only give diminishing returns for the added costs. Im many cases it isn't really cost effective at all, just a search for the extreme limits of water cooling.

About the oc/quiet: I think you can get the impression that eus are more interested in quiet than in ocing because there are some major (well, relatively) manufacturers in Europe, mainly in Germany, that manufacture well designed, but rather expensive watercool equipment. The market for that kind of expensive stuff probably exists of people who are not so much tinkering with their computer to get that last Mhz out of it, but who want a quiet and trouble free computer. That's why they are willing to spend money on it to get tested and tried stuff that doesn't look like it's homemade. Ocers may be more inclined to do it all themselves, be creative and make their own waterblocks, and take some trouble for granted. Those (German) manufacturers also host messageboards that became communities for watercool enthousiasts, and we eus keep reffering to them on Procool and other message boards. But you know I don't like speculating without testing the conclusion afterwards, so about flowrate:
Unfortunately, this guy(Henrik Reimers), only writes in German, but I give you the link anyway, and I have attached the diagramm, and some explaination:
http://www.henrik-reimers.de/kuehlung
Reimers has a setup with a waterblock, three pumps that are switched to alter the flowrate. There is a measuring device in the loop (I wish he was my neighbour
)to measure flow rate, and the water is kept at a steady temperature.
When varying the flowrate between 32l/h to 72l/h, the temperatures of the cpu vary no more than 1 C, the highest value not necessarily appearing at the highest flowrate. Given how hard it is to keep the watertemp steady and to measure cpu temps, he puts the variance down to the measuring, with which I must agree.
Later in his article, he does the same with a radiator, with the same results.
I also must agree with you that it can be just nice to do everything to get your flowrate up, and that those fat tubes look impressive in a case. But I rather keep my case tidy with narrow tubes, helping airflow and keep my temps down that way.
