Context Before
Now, how does Nvidia cool this heat monster, given that Vera Rubin’s power consumption and heat generation is roughly double that of Blackwell? Before answering, it is worth adding another consideration.
Evidence
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.
Context After
With less temperature differential, you need higher water/coolant flow to remove the same amount of heat. In Blackwell reference architectures, the ceiling temperature is around 65C.
② Atomic Claim
較高的 inlet temperature 雖能提升 energy efficiency，但當 inlet temperature 接近 maximum outlet temperature、delta-T 收窄時，cooling 會變得更困難。
