Context Before

Rack Level Infrastructure: Thermal

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. For many (for Mr. Market more broadly!) 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. We instead view this as a continuation of existing trends.

Evidence

Blackwell is already capable of operating with inlet water temperatures above 40C (see for example Supermicro’s DLC-2 system)

Context After

② Atomic Claim

Blackwell 已能在 40°C 以上 inlet water temperature 運作,例如 Supermicro DLC-2 system。
