Well, this has been mentioned before. I think I should note that when I touch this block, it is not hot. That is, when I touch the block as close to the core as possible, I cannot sense a temperature difference. This tells me two things. First, I'm doing a pretty good job of transferring the heat to the water. Second, a larger base will probably have little to no effect on cooling.
I don't understand why people think that a thicker base will spread the heat quicker. This is backwards. A thinner base will spread out heat faster than a thicker base. This is so, because the heat input is constant. This makes the base (at the die) hotter, due to the smaller temperature gradient through the copper. Heat will move through mass faster when there is a greater temperature difference between the center and the edges. If thicker was better than all the air cooled heatsinks would have thick fins.
In any case, moving heat through copper is exactly what I *don't* want. I want to move the heat to the water.

Why in that direction?
The original idea was to create breaks to the flow, to add turbulence to the water. If I change the direction, I won't get any turbulence.
