Earlier this year, Nvidia announced that it had made some new developments in relation to water usage around data centers. It claimed that its Blackwell data center hardware “boosts water efficiency by over 300x,” with the hardware now liquid-cooled to lower temperatures, namely, to use less water. Nvidia also detailed in June 2026 that it is actually managing to cool its hardware with 45 degree Celsius (113 Fahrenheit) liquid, using the closed-loop systems that the latest hardware incorporates to shave off even more water usage by the data center racks.
The closed-loop design means that once the water goes in, it will rarely need to be refilled, with the water inside constantly recycled through the system. On paper, and in certain working data centers, this has seen the amount of water used by the cooling reduced. Future data centers using Nvidia’s hardware will also have closed-loop designs at the start. However, that doesn’t mean that Nvidia has solved…
