>How do you cool it?
I've wondered whether little micro-filament heat pipes sandwiched right into the chips might be possible, all plumbed into a heat exchanger on the side of the die that can be directly cooled, facilitating the extraction of heat from deep within the stacked chips.

- Arrath 4y agoInteresting, thank you! Direct water cooling huh. With channels right in the silicon I imagine water purity is just that much more important. God help you if the water gets gunked up with disintegrating gasket material[0] and blocks some of those channels off, or even worse, conductive stuff.

- Coffeewine 4y agoI don't know about production chips with such things integrated, but it's certainly been tried. The below article is from 2008. https://www.eetimes.com/ibm-git-demo-3d-die-with-microchannel-cooling/ https://www.eetimes.com/ibm-git-demo-3d-die-with-microchanne...
