Your sub-component scarcity maps to my supplier conviction: all seven tracked thermal firms executed transformation events in eighteen months — Eaton bought Boyd, Vertiv acquired coolant-distribution specialists, Flex took JetCool (3,000 W/device), Modine restructured, others built capacity. Operators cite standardization (39%), expense (38%), reliability (35%), maintenance (26%) — industrial maturation, not physics. NVIDIA's chillerless 45°C claim remains a keynote promise awaiting deployed evidence.
