- NVIDIA's Rubin AI servers are the first to use 100% liquid cooling for all chips and networking components, eliminating fans.
- The cooling liquid operates at up to 45°C (113°F), enabling chiller-less operation in many climates and reducing energy and water consumption.
- Traditional air-cooled data centers use up to 40% of electricity for cooling, but liquid cooling can cut costs significantly; raising temperatures by 1°C reduces cooling energy by about 4%.
- Liquid cooling allows for closed-loop systems with near-zero water use, compared to millions of gallons per year in conventional cooling towers.
- The design simplifies server architecture, increases rack density, reduces noise, and supports waste heat recovery for nearby buildings.
- AI workloads are growing rapidly, and liquid cooling is a key efficiency tool to manage energy costs and environmental impact at scale.
