# Nvidia Advances Water-Efficient Data Center Cooling

Nvidia’s Rubin-generation reference design circulates liquid at 45°C (113°F) across rack chips and networking components, allowing dry coolers to bring data-center cooling water use close to zero in favorable climates. The design points to potential demand for liquid-cooling equipment and retrofit work, but it is not a government solicitation or contract award. Hotter locations may still need backup chillers, while older facilities may require substantial piping and power-delivery upgrades.

- Procurement teams evaluating data-center expansions or upgrades can assess liquid-cooling and dry-cooler specifications alongside facility climate and water-use goals.
- Contractors and equipment manufacturers may find retrofit opportunities, although legacy piping and power-delivery constraints could materially affect project scope and cost.
- Organizations should account for backup chiller needs in hot climates; the design’s near-zero water-use potential is climate-dependent.
