Context Before

Vera Rubin will be able to operate at a 45C inlet temperature, but Blackwell is already capable of operating with inlet water temperatures above 40C. Major system vendors such as Lenovo and HPE have also been discussing 100% liquid-cooled architectures operating at 45C since early 2025. In 2024, HPE announced an industrial cooling system based on full liquid cooling, and similar approaches have long been used before in HPC.

Evidence

Lenovo discussed the next generation of its Neptune liquid solution at the 2025 OCP Summit, which is fully liquid-cooled

Context After
