NVIDIA's Rubin AI Servers Use 45°C Liquid Cooling for Greater Energy Efficiency
By
Josh Parker
Summary
NVIDIA's new Rubin generation AI servers achieve 100% liquid cooling with coolant running at up to 45°C (113°F) — hotter than a typical hot tub. This counterintuitive higher temperature threshold enables greater energy efficiency by reducing the energy needed for cooling. The system uses a closed-loop liquid cooling design with no fans, covering every chip and networking component. This represents a significant efficiency leap in data center infrastructure for AI workloads.

· 3 pulledThe Rubin generation of NVIDIA AI infrastructure is the world's first to achieve 100% liquid cooling — every chip, every networking component, cooled entirely by liquid in a closed loop with no fans anywhere in the system.
That higher temperature limit is precisely what makes them more energy efficient.
