I had a few ideas which might improve the performance of the Cascade block.

1)Enchanged inlet:

instead of injecting the water in the shape of a circle, I'd do it rectangular (the shape of the core in other words).
I'd use an "Adapter"(upper part of the block adapts the round fitting (from the water inlet) to a rectangular opening (to inject the water on the core).
You can compare it with a fan shroud.
(I think the less steep it is, the better the water gets divided over the jets)

2)Enchanged outlet:

First of all, dual outlets. (to get the water away better, and to do it more balanced)
Second, "preparing the shape of the waterflow to enter the outlet. This means I would change how the bottom area near the outlet.
It 'll be more clear when viewing these pictures: (it are drawings of a block that never made it, but the idea of enchanging the path to the outlet still makes sense to me)

3)Getting the water away better + higher "outlet flow"

I am aware that, when looking in the holes with the jets, the exit velocity should be smaller then the inlet velocity. (I believe this is to have a good pressure, to smash the boundary layer)
That is in fact determined mostly by the cup diameter I think. So I think this could be a nice improvement to make.

1) classic cascade: the water getting out of the cups meets the outer water getting out: chaos.
2) enchanged cascade: the water gets away nicely.

4)Much deeper cups (and longer cups). For the simple reason that when using a deeper cup the 2nd cooling effect is better (the water travelling upwards passes more copper)
Although it would make the block cost more, for just a very small performance increase.

5)Enchanged jets:

1)enchanged outer surface to create turbulence: some "obstacles" on the outer side of the jet. Lets say if you put tiny little rings over the jet.
This would create some turbulence, so the water would hit the copper better (2nd cooling effect)
2)echanged underside of jets to improve waterflow: very little detail.

Enchaning the jets like 1) and 2) would probably be very hard and with a very little performance gain (?), but it came in my mind, so why not put it with the others... ;-)
