Direct-to-chip cold plate

Cold plate on the package, air for the balance of the node.

Why this part

A partial commitment: liquid on the processors and accelerators, air for everything else. Summit and Sierra are built this way. It is the pragmatic option when the hot components are a minority of the node, and it stops being enough once memory, network adapters and voltage regulators are themselves substantial heat sources, which is roughly what happened by 2022.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
