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.
