At CES 2026, Nvidia unveiled a new data center cooling system, claiming to eliminate water usage within facilities. This innovation, launched alongside its next-generation Rubin AI data center processor, could solve one of AI's biggest environmental challenges, according to 24/7 Wall St. and TechCrunch. The explosive growth of AI data centers exacerbates global water scarcity, yet Nvidia's new closed-loop system promises to end water consumption for cooling within these facilities. Traditional data centers demand immense water, a practice now unsustainable.
Nvidia is not just an AI hardware leader; it is becoming a crucial enabler of sustainable AI infrastructure. This new system could set a new industry standard for data center design. Companies neglecting similar closed-loop cooling solutions will likely face mounting regulatory pressure and public backlash as AI's water footprint becomes an undeniable environmental liability.
How Nvidia's Closed-Loop System Works
Nvidia's new DSX AI factory architecture employs a closed-loop liquid cooling system. This system recirculates coolant without evaporation, reducing reliance on traditional cooling infrastructure, reports 24/7 Wall St.. The coolant, a mixture of three-quarters water and one-quarter propylene glycol, operates effectively at temperatures up to 115 degrees Fahrenheit (45°C), according to Gizmodo. This warm-water approach allows facilities to use outside air for cooling, significantly cutting power consumption and water usage. A top Nvidia executive believes this next-generation AI infrastructure could largely address data center water concerns, Axios notes.
This innovative design conserves water and boosts energy efficiency by leveraging ambient conditions and specialized coolant. Operating at 45°C (115°F) redefines data center heat management, positioning Nvidia to lead in energy-efficient AI infrastructure.
