Okay, I have some more hard data from the results I've been gathering for a water-block review.

For the Eheim 1048 & 1250, my block is seeing indistinguishable performance difference. The 1048 pushes 4.2lpm through the block, the 1250 6.3lpm. With a high pressure high-flow Pondmaster 4200, there's 10lpm being pushed through the block.

For all of those pumps, my block is at least a 4C clear lead over any other block I'm using (Maze 3, Cyclone 3 [Swiftech copy which performs exactly like a Swiftech], Cyclone 4, Cyclone 5) for bare CPUs (AthlonXP, Duron), and 2C for P4's with the IHS, for a CPU pushing out >75W of actual heat, in relative terms, that's a >20% improvement. I'm sorry if 20%+ doesn't seem like a big jump to you. To me it is.

ie. the same benefit is seen across a wide variation of flow rates and pumps.

The radiator just sets the water temperature that enters the block. Changing the radiator has the same effect (for all intents and purposes) on all blocks. The only effect changing a radiator can have on block performance is if it's radically restrictive.

ie. yes - there can, is and does exist ways to design blocks for better performance in almost all commonly used circumstances (I haven't yet tested for <0.5gpm, or >3gpm).

I'm just getting frustrated at your continuing attempts to play down the importance of water-block design when there's clearly a long way to go ahead of what the current market blocks give.

It may seem I'm trying to boast here about my achievements, but unless I come up with something factual to counter your statements, then any contradiction to your statements would be merely speculation, as yours are.

I have solid proof that you can do better.

Do you have solid proof that you can not?

This is what's frustrating me.
