Nvidia announces a data-center cooling approach it describes as “100% liquid cooling,” designed to drastically reduce water consumption used for facility cooling. According to the company, conventional cooling-tower setups can require about 2.6 million gallons of water per megawatt per year. Nvidia says its liquid-cooling architecture can bring that figure close to zero, potentially cutting cooling-related water use by up to 100% in suitable environmental conditions.
The technology centers on moving cooling away from water-heavy evaporative systems and toward liquid-based cooling methods for data-center components. Nvidia positions the design as a way to lower both dependence on cooling water and the overall water footprint of data centers, while maintaining cooling performance needed to run high-performance computing hardware.
The claims are presented in terms of estimated water-use reductions rather than measured results from a specific deployment in the articles provided. Nvidia’s announcement focuses on how the architecture could perform under favourable climates and compares the projected water use against standard cooling-tower baselines.
