I think it is unreasonable. They require restriction to do what they do. Turbulence in any form causes restriction, and turbulence in any form helps cooling. Good waterblocks use lots of turbulence in good places, and thus restrict lots relatively. You're sacrificing the (usual) end for a (usual) means.

yea, but he should mod the SlitEdge,
remove the internal fins so it will flow more

Hmmm - at ~1.5PSI @ 1gpm, the new block is obviously far from being desirable.

Is there a picture how the BeCooling SlitEdge looks from inside?

I just realized how easy that could be made into a Lumpy Channel style block!

Thanks for the photos.

Anyway, I understand the need of turbulence and surface for an efficient heat transfer.
But why cant the block be designed to cause turbulence without narrowing the total intersection surface that the water has to overcome at any given time.

An 1/2" ID tube has an intersection of 127 mm^2
My system uses this intersection surface in every place ( fittings ID, tubing ID, pump ID ), even the radiator allows the water to find its way through so there is always the minimum of 127 mm^2 the water has to overcome at any time...

SO, ideally, the w-block too would have a total inner intersection surface of at least 127 mm^2.
The point? Thats my idea of an unrestricted flow path.

I think you should explore that last thought some more If I understand you correctly, you are more interested in how much flow you get than you are in performance? The best blocks ATM are restrictive, for good reason, they perform better. Why? Because the point of restriction creates velocity over the die area. Your analogy to me is like someone going to a car dealer and saying, "I want a car with 500 HP, I don't care how fast it is but it MUST have 500 HP." The dealer shows you a car with 300 HP that smokes the car with 500 HP. You insist, "I must have a car with 500 HP." But sir...

why not ask for the best performing setup with the lowest noise level as well?

a bit to learn about fluid dynamics, you do have.

Um, what?
Do you really think that total cross-sectional area has everything to do with flow?
DO you think that one opening of 127mm^2 will flow the same as 100 tiny pipes, each with a 1.27mm^2 opening? Or 1000 even tinier pipes of .127mm^2 sized openings?
Think about it.

Think about it.

It's hard to describe what I want in my own language, let alone in another...

Of course a lot of tiny pipes restrict flow alot more then one big pipe. But thats another kind of flow restriction and is in my thought less restrictive, then pushing water through some tiny-winy holes with, lets say, 90% less cross-section area to create the jet effect...
90% less cross-section area for water to go through against, lets assume, 15% less area.
There's bound to be a difference.

I'll make one last effort:
I just don't understand the facination with "flow"...
who cares?
If a block flows half what another block does, with the same pump, yet keeps the processor 2 degrees cooler, which one is preferable????

I guess I am a hopeless case

To counter that thought:

If its just 2 degrees weaker then the high performance block, I'll take the block with half the restriction right away

to what point ?
how is lower performance better ?

ah yes, because it flows more
is this a water fountain ?

Exactly. Just what is it that is hoped to be gained by having a lower restriction weaker performing block?

What is the need for this low restriction? It has to be something other than performance based. Are we watering the garden or something?

I don't get it- why would you take the lower performing block?
it doesn't make sense, its just flow
or are you talking about boasting rights

Boasting rights?


There isnt really a scientific reason for such a design. But wouldnt such blocks allow efficient cooling with smaller pumps, leaving more "head" for longer cooling routes with more waterblocks and without stressing the system?
