NVIDIA's Rubin AI Servers Ditch Fans Entirely, Slash Data Center Cooling Costs by Millions with 100% Liquid Cooling
Summary
NVIDIA's next-gen Rubin AI servers eliminate fans entirely with 100% liquid cooling, running at 45°C to enable chiller-free operation, slashing hyperscale data center cooling costs by over $4 million annually while reducing facility water consumption by up to 100%.
Key Points
- NVIDIA's Rubin generation AI servers introduce 100% liquid cooling, running coolant at up to 45°C with zero fans, eliminating the traditional hot aisle/cold aisle air-cooling model used in data centers.
- The 45°C liquid-cooling system enables chiller-less operation using outdoor dry coolers in favorable climates, reducing facility water consumption by up to 100% and saving hyperscale data centers over $4 million annually in cooling-related costs.
- The closed-loop liquid cooling design, using a 75% water and 25% propylene glycol mixture, captures heat directly at the chip, increases rack density, and sets a new industry standard as all cloud providers building on the Rubin platform adopt the transition.
