GPU racks are stalling on cold-plate and CDU capacity, not chip supply
tengyanAI · x · 2026-07-23
The real bottleneck for GPU rack deployments is increasingly cold-plate and CDU capacity, not chip supply.
The post argues that:
- GPUs may arrive on time, but racks still sit idle waiting for cooling qualification
- hyperscale retrofits for direct liquid cooling take quarters, not one procurement cycle
- that delay gives vendors like Vertiv pricing power
- Eaton’s Boyd Thermal business is reportedly benefiting as backlog has doubled in six months
