Nvidia announces liquid cooling system that promises to reduce electricity consumption and cut water use by up to 100%
Summary
Nvidia has announced a liquid cooling system for data centers that aims to dramatically reduce electricity consumption and water use, potentially up to 100%. The system uses a closed-loop coolant with 75% water and 25% propylene glycol, operating at around 113°F (45°C) and exhausting heat at about 131°F (55°C), enabling the use of outdoor dry coolers in many climates. While this approach promises significant efficiency gains, the article notes sustainability challenges and considerations for deployment in varying ambient conditions.
