It's understandable that some of the most prominet users in this forum simply lost interest in this subject. They have reached a "plateau" in their own aspirations as far as WC is concerned.
No more the need to prove something.
That doesn't imply there isn't any room for big improvements.
Some threads tried to debate certains aspects of this alleged necessity of a evolution in the WC market (e.g. BillA:"do we need a "low end" cooling section?"; Joe:"How safe is water cooling these days"; "US VS German systems-advantages/disadvantages"), the focus on the eternal question of reliability, tubing permeation, etc.
What happened is that the die hard users in Procooling still can't accept the manufacturers "invasion" of their little feud or playground.
Instead of voicing coeherently their concerns /suggestions, the topic of debate soon was adulterated and no one could reach a valid conclusion, and so stagnation overcame.Why bother?

So far what is still the best WC example of this industry? - the Apple G5 (with some leaking problems).
Look what happened with the radiator/silence debate here in Procooling.
Something new was developed.
To me one of the worst byproducts of the Watercooling market is the modding scene, where WC products are designed and targeted with no real contribution to a system security/reliability.

Everyone still wants everything at the same time - sort of a hybrid Porsche. Is it feasible?Perhaps, but not with this mentality.
