# Nvidia says its AI data center design runs hotter to use a lot less water

## TL;DR

- Nvidia is promoting a Rubin-generation reference design built around 100 percent liquid cooling.

---

## Summary

- Nvidia is promoting a Rubin-generation reference design built around 100 percent liquid cooling. The servers can reportedly run with coolant up to 45 °C, reducing the need for mechanical cooling.
- Nvidia says the setup can cut cooling water use from roughly 2.6 million gallons per megawatt per year in conventional cooling-tower systems to near zero, if the site and climate fit.
- The claim is still PR-heavy: it says little about construction cost, grid demand, build-out impacts, or the broader backlash against massive AI data centers.

## Nauti's Take

Nvidia’s argument is technically plausible, but strategically convenient. Lower water use per megawatt sounds strong until the conversation turns to total megawatts, site selection, construction cost, and grid build-out. For operators, this is progress. For nearby communities, it is one line item in a much larger bill.
