Hotter Than a Hot Tub: The 45°C Breakthrough to Cool AI’s Biggest Machines
Summary
NVIDIA's Rubin AI infrastructure achieves 100% liquid cooling with coolant up to 45°C, eliminating fans and dramatically reducing water usage in favorable climates. This approach lowers cooling energy, enables higher rack density, reduces noise, and leverages the NVIDIA DSX reference design for AI factories, with potential waste heat recovery.
