# Nvidia's New Data Centers Run Hotter Than Expected Aiming to reduce water consumption to zero with liquid cooling technology. - **Source:** [SlashGear](https://www.slashgear.com) - **Published:** 2026-07-22 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/5d468ce7-d18d-4ca9-80f4-b714d6a4c403 ## The Environmental Cost of Data Centers Hyperscale data centers consume increasing amounts of energy and water as they grow. Traditional cooling methods rely on open-loop evaporation, leading to significant water loss. New technologies are being developed to reduce water consumption. ## Nvidia's Closed-Loop Solution Nvidia introduced a 100% liquid cooling technology with its new DSX AI platform. This system operates at temperatures up to 45°C and nearly eliminates water consumption. The coolant mixture consists of water and propylene glycol. ## Energy Savings with Passive Radiators In Nvidia's system, the liquid is directed to passive radiators after leaving the racks. These radiators dissipate heat, reducing the need for mechanical cooling. However, the effectiveness of this method depends on geographical conditions. ## High Power Consumption Makes It Necessary Nvidia's new Vera Rubin architecture consumes 2,300 watts per GPU, making air cooling impractical. Full liquid cooling becomes a necessity to meet this high power demand. ## The Reality of Water Footprint Data centers' water consumption isn't limited to cooling. Fossil fuel power plants used for electricity generation also consume vast amounts of water. Nvidia's solution reduces water use within data centers but doesn't eliminate the overall impact. ## A Step Toward Sustainable AI Nvidia's innovation is a significant step toward reducing the environmental impact of the AI industry. However, more comprehensive solutions are needed, including energy production and other factors. Green technologies will become standard in future data centers. ## Sources covering this story - https://www.slashgear.com/2218409/why-nvidia-data-centers-run-at-high-temperatures/ — --- _Summary written by Brifing from the original reporting.
