Ok, I won't argue with you, but how much flow did took to do that, (that was probably that center inlet, two outlet block right), but still did you test at the same condition with the same copper block and see the difference of just few degrees?
And that large chanell, small chanell labeling for block is just not good. It's all in the basic equation for heat transport it consist of heat conductivity (material properties) and heat transfer (preasure,temperature, velocity properties of the tested fluid, and shape and quality of the surface properties). So with large chanell you get at the same pump output better flow-> higher velocity ->better heat transfer so that part of the equation become more important for total heat transport then the part of heat conductivity , that's what makes you think that aluminium is better, but never the less cooper in same condition would still be better but the difference would be smaller, then in second case with small chanells where water flow would drop, and material properties (heat conductivity) begins to be more important in that equation, because it comes to heat spreading effect through the fins and whole block and here is copper supperior to AL.
I can't put it any simpler I have enough trouble explaining this from my language to english.
But to the utabintarbo main point, do you also argue my take on that, do you think that designing top AL block would result that the same Cu block would be top? This certanly won't be the case
