Blackwell deployments are systems, not loose GPUs. Cooling selection must align with the exact OEM rack, cold plates, manifold, CDU duty, facility-water envelope, and support agreement.
Reference-architecture suppliers
Vertiv has published a 142 kW GB300 NVL72 power-and-cooling architecture. Schneider Electric and Motivair, Trane and LiquidStack, and other integrated suppliers position portfolios around high-density AI factories.
Direct-liquid specialists
CoolIT publicly maps CHx2000 capacity to GB200 NVL72 racks. Accelsius and ZutaCore focus on two-phase direct-to-chip approaches, while specialist cold-plate companies work through server-OEM qualification.
Qualification rule
Use the current server OEM configuration and warranty as the controlling source. A supplier's general Blackwell claim does not qualify every rack, GPU generation, or facility condition.
