Context Before
So 45C cooling is not entirely new. 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.
Evidence
Only a small number of operators have removed chillers from the loop in favor of highly optimized economizer designs where climate permits.
Context After
Avoiding the compression step in mechanical cooling can deliver meaningful energy efficiency gains.
② Atomic Claim
只有少數 operators 在 climate 條件允許時，以高度最佳化的 economizer design 取代 loop 中的 chillers。
