Nvidia cools AI servers with 45°C water, no fans needed
Nvidia's latest AI servers use hot liquid cooling, with water entering at 45°C and exiting at 55°C, eliminating fans entirely. The approach handles higher thermal loads from next-gen GPUs while reducing energy consumption. It marks a shift from traditional cooling methods in data centers.
Meridian48 take
Hot-water cooling sounds counterintuitive but could be a practical solution for the rising heat density of AI hardware, though real-world efficiency and reliability remain to be proven at scale.
