Did I? I don't think so, thats how you see it from your point in your corner. You and me too just don't have the Overview to judge this...

many (most ?, all ?) of your observations are valid in a literal sense, and most are probably irrelevant wrt the wb's performance
- I say probably because I do not have data

But I have, look at page one, i posted a link to fluidus measurements there.

all this foolish babble about testing and flow rates, is it difficult to control and measure the flow rate on a test bench ?
-> only if one has a Mickey Mouse setup
so any wb can indeed be tested at any flow rate (if used with the appropriate connectors - as in those provided by its mfgr)

yes its difficult, because some blocks come without any barbs and some come with. and flowrate measurements are difficult because of doifferent restrictions of the blocks. You can ask pHaestus why you can't compare the maze4 and the cascade in the one diagramm, then he'll tell you why its difficult (or just read the articla about the maze4).
Another thing is the overall performance of a watercoolingkit. When you only measure the performance of the block with a highflow, you have forgotten the heat that the pumps dissipates to the water and the radsize...

opinions about wbs w/o data, even if based on good science, are only opinions
opinions about wb performance w/o data are always bullshit

this from someone who does know something about testing

Thats why i included w/o data and based my opinions on that. I know you know something about testing , i do read through international forums and your are a well known person BillA.

NO condescension involved, davidzo that was an excellent post

thx BillaA


@snowwie:
The maze4 indeed is a very different thing, but not the maze1-3 and other spiral/mazelike blocks.
The very interesting and good about the withe water was its exceptional good scaling at that time. That was because the higher flow was directly used against the boundary layer. In a block like a maze1 or even the MCW5000, it don't changes a much because the boundary layer stays still nearly the same, while the flow in the middle of the channels gets more (where we don't wanna have it)
an austrian company, Zern invented somes sort of Polytop back in the days of the mazelike blocks, to press the water against the walls of the channels and not to flow through the middle. That was one simple solution and there where other solutions to lower the boundary layer, but jets actually are much more efficient to make the increased flow usable to combat the boundary layer - and thats what makes a good block today, the thin boundary layer.
@The mcW462B is the type of block, which we germans call "Gleitschichtkühler", which means boundarylayer-cooler. The Innovatek flatflow is another example. Both are exapmples for designs which also scaled nicely like the Zerns from Austria, but not with jets like today.
