Context Before
Beyond the redesigned fanless front chassis and the 100% liquid-cooled compute tray, the most notable point in the Vera Rubin cooling architecture discussion was Jensen’s comment on coolant/water warm temperatures and the use of chillers.
Evidence
For many, the statement that Vera Rubin can operate with 45C inlet temperatures, potentially avoiding mechanical compressor-based chillers, was viewed as a major surprise for much of the cooling supplier ecosystem.
Context After
We instead view this as a continuation of existing trends.
② Atomic Claim
對許多人而言，Vera Rubin 可在 45°C inlet temperature 運行、因此可能避開 mechanical compressor-based chillers 的說法，對 cooling supplier ecosystem 是一大意外。
