Heat Is the New AI Bottleneck

AI data centers are hitting hard physical limits — not just from chips or power supply, but from heat.

Modern AI GPU racks now draw 120 kW+, far beyond what traditional air cooling was designed to handle. Air can only move so much heat per cubic meter. Once racks cross ~50 kW, physics starts winning: chips overheat, throttle, or fail — not because the hardware broke, but because the cooling medium hit its ceiling.
