I just noticed this was a poll.

Anyway I am refusing to vote simply because I don't know the answer even though I have done it. From my experience the die area is to small. The heat is to concentrated and not enough surface area for water to absorb the heat. Especially with waters low thermal conductivity. Copper spreads the heat out so water has more surface area to pick it up. The only way I can figure to make direct die more efficient is simply more flow.

Much like a radiator. The faster you can push water through it the more heat it will dissipate. Problem is the faster you make the water go the more heat gets added into the water by friction and the faster pump.

Until I see irrefutable evidence I have to go with my experience and say a good water block will beat out direct die cooling. I can't say for 100% sure though.
