What is the right way to cool a 51.2T NPO switch? A Celestica ITherm 2023 paper answers: cold-plate liquid cooling at 2 LPM leaves margin for both the ASIC and the OEs. The real bottleneck is not the 835W ASIC but the 16 optical engines capped at a 70°C case temperature.

Celestica grew revenue 62% and EPS 83% YoY with a record operating margin, raising full-year guidance for the second time. The real signal: OpenAI custom rack orders surfaced, AMD Helios scale-up became a multi-billion-dollar pipeline, and 2027 growth is set to be even faster.
