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.

Evidence

Major system vendors such as Lenovo and HPE have also been discussing 100% liquid-cooled architectures operating at 45C since early 2025.

Context After

In 2024, HPE announced an industrial cooling system based on full liquid cooling, and similar approaches have long been used before in HPC.

② Atomic Claim

Lenovo、HPE 等 major system vendors 自 2025 年初起，也一直在討論以 45°C 運行的 100% liquid-cooled architectures。
