Stupid question: could you literally just put a grid of coolant tubes through a cube processor? Think like the shape of control rods for a nuclear reactor. Power supply is also tricky with a cube chip, but could you electrify the coolant flowing through the tubes? Half of the tubes positive, half negative. So the tubes through the cube double up thermal and electrical conductance. EDIT: stupid idea #2: what if you also used peltier cooling to route heat out of hot spots?

You could. Tighter cooling integration for denser ICs is an area of active research but is something that needs to be economical at scale to matter. If a rack full of flat chips does more work per dollar than a complicated-to-manufacture 3d-stacked coolant-permeable IC, there's not a very strong argument for building them. Peltiers are inefficient as all hell and not likely to be part of such a tightly integrated solution.
