Microsoft responds, highlighting its liquid cooling heat exchanger as a closed-loop system that enhances cooling in existing data centers while supporting AI and hyperscale workloads. Experts note trade-offs between air cooling, water cooling, and hybrid approaches, with concerns about energy use and water consumption. Nvidia's Blackwell installation for OpenAI uses two GB200 NVL72 racks with 72 GPUs each, showcasing the push to scale AI infrastructure. Microsoft says it aims to be carbon negative, water positive, and zero waste by 2030, and has pursued breakthroughs in on-chip cooling and zero-water designs for future data centers.
