NVIDIA’s Ali Heydari on the AI Revolution

We’re back! And we’ve gone big for the first episode of season 3! Today, Ali Heydari, Director of Data Center Cooling and Infrastructure at NVIDIA, joins hosts Charlie Jelen and Dan Gentry to unpack how AI “factories” are reshaping data center design and why Ali thinks the AI revolution is the biggest change to the our lives since the industrial revolution. Ali explains why geometry (not thermodynamics) pushed the move from air to liquid, why NVIDIA standardized on PG25 for direct-to-chip cooling, and how digital twins in Nvidia’s Omniverse help right-size everything from chillers to dry coolers. We also dig into the tradeoffs between higher loop temps and rack density, and why cross-industry collaboration matters more than ever.We also have:HVAC Headlines: Why Legionella is a serious risk of poorly maintained HVAC equipment and how to avoid it, plus, why prices are soaring in the country’s largest grid region.Stat of the Day: Can you guess which states lost the most power in 2024?We want your hot takes and questions!
