Nvidia's Rubin liquid cooling uses 113°F low-temperature coolant to achieve near-zero water consumption and significant data center energy cost reductions.

NVIDIA has introduced Rubin liquid cooling technology for its smart servers, which operates using 113°F low-temperature coolant. The system is engineered to achieve near-zero water consumption while delivering significant reductions in data center energy costs.

The innovation addresses two critical pain points in AI infrastructure operations: escalating power consumption and water usage in large-scale deployments. By enabling efficient heat dissipation at lower temperatures with minimal water draw, the Rubin system reduces the operational overhead that typically constrains data center expansion and profitability.

For the AI buildout, this represents a meaningful step toward more sustainable and cost-effective infrastructure scaling. As demand for GPU capacity continues to drive data center proliferation, thermal management breakthroughs that cut energy expenditure and water dependency make deployment economics more favorable—particularly important as colocation and power availability become increasingly constrained in key markets.
