Hmm, made this silly design here a while ago and discarded it right away. Found it recently tho and it made me wonder how this would perform... Haven't got high hopes, no jet impingement or anything
Its a four inlet

single outlet design, and I've been trying to create turbulence around the pins (red square) right over the die, using a circular waterflow.
I'm fearing there might be stagnant water right under the inlet
As base, maybe an pin based 1u heatsink would do (if I can find one).
What do you blokes think of it?
