I presume per rack? Can you imagine something radiating that much energy into a space in your home?

  I guess because I have actually set foot in a data center I don't imagine literally every product in my home.

  It's mandatory liquid cooling, so it's meant to be attached to a specialized liquid cooling loop that gets the heat outside the building. This is far beyond the practical maximums of like 10 to 15kW per 44U cabinet front to rear air cooling for 'regular' rackmount server stuff.

    Indeed. You need 45 to 60 liters per second of cooling water flowing over a Cerebras wafer every minute to keep it under 90C. And that’s assuming the water leaves at 90C… More realistically, you need much more cooling water.

      CS-3 used 100 liters of water with a cold plate (https://www.brownstoneresearch.com/bleeding-edge/ai-infrastructure-investment-continues-to-increase/ https://www.brownstoneresearch.com/bleeding-edge/ai-infrastr...). But you can also use refrigerants with a cold plate (https://eng.umd.edu/engineering-ai-public-good/cooling-data-centers-safer-two-phase-fluids https://eng.umd.edu/engineering-ai-public-good/cooling-data-...) or dielectric fluid in total immersion. Until they find a more power-efficient design, my guess is total immersion will come back in style.
