My apologies. The language barrier is somewhat difficult to bridge. A number of your statements appeared to be quite sarcastic to a native English-speaking person. The internet often makes it difficult to interpret the meaning of people's statements, let alone when dealing with translating between different languages.
Indeed, I feel that some people in the USA have gone too far with large and powerful pumps, and noisy fans on their poorly matching radiators. Too much effort is spent on solving the cooling problem with brute force.
At Overclocker's Australia a
recent poll seemed to show that many Australian's who water-cool have a desire for a system that really is not that different to what the Europeans are trying to achieve. Perhaps the only real differences between the two is the preferred size of the tubing, although I feel that in time and with some good testing it will be shown that 3/8" ID tubing can perform almost as well (within 0.2C) of a 1/2" ID system even when given a pump like the fairly strong MCP600.
I would much rather see a quiet and efficiently set up cooling system. I believe that such a system sits roughly midway between the very low flow efforts of some of the European setups and the excessively powerful USA setups.
