Nvidia Is Cooling Its Supercomputers With Hot Water — And It's More Efficient Than Anything Before It Nvidia's Vera Rubin chips use 45°C water instead of cold water to cool AI data centers. No chillers needed. Closed loop. Near zero water waste. Cooling currently eats up to 35% of all AI data center electricity. Jensen Huang called it so incredibly efficient. If this is the kind of AI breakthrough you want to see more of, follow for more. #Nvidia #AIEnergy #DataCenter #JensenHuang #TechNews
