Innovation Hotter Than Warm Water: 45°C Technology That Cools Massive AI Equipment

NVIDIA's next-generation AI infrastructure, the Rubin platform, is the world's first to adopt 100% Liquid Cooling. Every chip and networking component within the system is cooled via a fanless, closed-loop liquid system.

The core of this technology lies in its ability to operate coolant at temperatures up to 45°C. While traditional data centers have relied on massive amounts of power and water for cooling, high-temperature liquid cooling offers the following benefits.

• Improved Energy Efficiency: By raising the cooling temperature, power consumption used for cooling is dramatically reduced.
• Zero Water Consumption: The Dry-cooler-based closed-loop design almost completely eliminates water loss from evaporation.
• Reduced Operating Costs: For a 50MW hyperscale facility, this can enable savings of over $4 million annually.

In the past, there was a perception that keeping data centers cold was efficient, but the latest silicon processors are designed to withstand high internal heat. NVIDIA's DSX reference design leverages this high-temperature liquid cooling to present a new industry standard that innovatively reduces energy and water usage in data centers.
