Fans, heatsinks and hot aisles — sufficient until ~40 kW per rack.
您正在查看一条技术记录：AI 硬件的一个基础构件——它的功能、谁来制造，以及哪些芯片和系统使用它。
Traditional data centers move heat with server fans, hot/cold aisle containment and CRAH units. Air remains fine for storage, CPUs and inference cards, but at Blackwell-class densities the physics stop working: a 120 kW rack would need hurricane-grade airflow. Air's era at the AI frontier ended with Hopper.
