Context Before
On the liquid side, the TCS circulates coolant to the cold plates at roughly 40C and returns it at a higher temperature, while the CDU transfers that heat into the facility water loop, which can enter the CDU at approximately 37C.
Evidence
So 45C cooling is not entirely new.
Context After
Even with this capability, most operators deploying Blackwell are still designing for 20-30C water temperatures. As a rough approximation, current Blackwell inlet temperatures are around room temperature, with outlet temperatures in the 40-50C range. Only a small number of operators have removed chillers from the loop in favor of highly optimized economizer designs where climate permits.
② Atomic Claim
因此，45°C cooling 並不是完全新的概念。
