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. Only a small number of operators, such as Firmus, have removed chillers from the loop (even with systems like GB200) in favor of highly optimized economizer designs where climate permits. Avoiding the compression step in mechanical cooling can deliver meaningful energy efficiency gains.
Evidence
Now, how does Nvidia cool this heat monster, given that Vera Rubin’s power consumption and heat generation is roughly double that of Blackwell?

② Atomic Claim
問題是：在 Vera Rubin power consumption 與 heat generation 約為 Blackwell 兩倍的情況下，Nvidia 要如何冷卻這個高熱負載系統？
