I see thats pretty much as expected.

This is clearly a case for jet impingement if there ever there was one. heff for that is 120 W some area (centimeters squared??).

My plan for ultra cheap mass market wter block was to use my local uni, maker of the worlds smallest holes to make a simple holed plate for jet impingement, sub milimeter. The key thing with jets is the smaller they are the better as cooling scales with size (relative area gets smaller per jet but relative velocities increase much faster). The jets need to be desinged to provide a good cross flow (flow across other jets to help them cool). If done right the numbers in papers i have read indicated it could just about beat current blocks.

Because of the method of manufacture though it should be cheap.
