Its never actually going to be even.
What I was going for, on my block anyway, was to use the natural property of water following the path of least resistance, to aid cooling.
What I figured was that the centre of the block, right over the middle of the core, in my block anyway, had very very little floe resistance, eg, 3mm between inlet and outlet.
As the grooves get bigger, and longer, the flow resistance increases, as does the distance the water has to travel to get out.
if you're cooling an area the size of a CPU core, this is very significant, you want a lot of flow over the core, but less over the mop-up areas, around the core.
The design, without forcing the water, allows this to happen naturally.
With a TEC, you ahve to use a HUGE area, and I don't think the same principals apply.
In my eyes, this is not a TEC block, by any means, the original Maze1 would be a better bet.
