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. 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.
Evidence
With less temperature differential, you need higher water/coolant flow to remove the same amount of heat.
Context After
In Blackwell reference architectures, the ceiling temperature is around 65C.
② Atomic Claim
當 temperature differential 較小時，要移除相同熱量，就需要更高的 water/coolant flow。
