uhm... ok. i guess all them darn fluid dynamics classes I took didn't help much. let's see what you wrote again: there is turbulence over the core, u admit that... good. then, when using a pelt, you want even heat transfer throughout the block, right. that's why there is evenly distributed turbulent bends on the outer diameter and a relatively thick base plate...
saying this block will perform like a maze3 is garbage, it already is 7 degrees K cooler than my old maze3 during preliminary testing, even at higher than normal voltages.
also, regarding flow. I modeled my whole system, and the actual bottleneck with over 80 percent of the preassure drop is my D-tek customs radiator, not the block
Voila
also, I kept "machinability" in mind when designing this block... u seemingly haven't done that in your fantastic design! Getting that milled on an EDM is going to set you back hundreds, if not thousands... My block took about 30 minutes milling time on a computer controlled 3 axis machine...
