Nvidia Pushes Coolant to 45 Degrees, Trading a Cooling Problem for a Power Dividend

Warm-water, single-phase cooling (the coolant stays liquid) across the Vera Rubin generation lets data centers shed heat using dry coolers for much of the year, reducing the largest use of electricity in a facility that is not the computing itself.

Nvidia detailed cooling for its newest AI servers that runs the working liquid at up to 45 degrees Celsius, with coolant entering a fully liquid-cooled chip at 45 degrees and leaving at roughly 55 after absorbing the heat. The company says…
