15kW dissipated over that area isn't particularly challenging for an industrial water cooler - within reason, you can just keep cranking up the flow rate. What'd scare me is power delivery, because they've probably got >10,000 amps going to the die.

- Dylan16807 3y agoDoing it with all that water needing to get everywhere is definitely a feat. But the power itself isn't too bad. A square millimeter of wire can comfortably carry 20 amps, and you can scale that up pretty straightforwardly. It looks like each of those 84 rectangles has to deal with 240 amps and has multiple square centimeters of contact with the voltage regulator card above it.
