There's an image on their website[1], pretty huge water pumps.
"To solve the 70-year-old problem of wafer-scale, we needed not only to yield a big chip, but to invent new mechanisms for powering, packaging, and cooling it.
The traditional method of powering a chip from its edges creates too much dissipation at a large chip’s center. To prevent this, CS-2’s innovative design delivers power perpendicularly to each core.
To uniformly cool the entire wafer, pumps inside CS-2 move water across the back of the WSE-2, then into a heat exchanger where the internal water is cooled by either cold datacenter water or air."
