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.

Evidence

In 2024, HPE announced an industrial cooling system based on full liquid cooling

Context After

, and similar approaches have long been used before in HPC.

② Atomic Claim

2024 年，HPE 發布以 full liquid cooling 為基礎的 industrial cooling system。
