Context Before

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?

Context After

Before answering, it is worth adding another consideration. Warmer inlet temperatures, while improving energy efficiency, can make cooling more challenging as inlet temperatures approach the maximum outlet temperature and the delta-T tightens.

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？
