Nvidia says its AI data center design runs hotter to use a lot less water Nvidia claims its new liquid-cooled data center design for its Rubin generation servers can reduce water usage to “near zero” by operating servers at higher temperatures, up to 113 degrees Fahrenheit. This approach captures heat directly at the chip and uses liquid loops to efficiently reject heat, achieving up to a 100 percent reduction in water use compared to conventional cooling systems. While this addresses water and power consumption, it does not cover all concerns like construction or power generation needs.

• Nvidia’s Rubin generation reference design for AI data centers uses 100 percent liquid cooling.
• The design claims to eliminate massive amounts of power usage and “pretty much all water usage.”
• Servers are run hotter, up to 113 degrees Fahrenheit (45 degrees Celsius), for efficiency gains.
• Heat is captured directly at the chip and transported through liquid loops.
• Water use is reduced from approximately 2.6 million gallons per megawatt per year to near zero.
• The design does not address all concerns, such as construction and power generation requirements. Continue reading https://www.theverge.com/tech/954139/nvidia-data-centers-rubin-liquid-cooling
