Nvidia moves to liquid cooling with next-generation DGX servers

Future DGX systems will not only be more powerful, but also more efficient thanks to the use of liquid cooling.

Here's What We Know

This solution is the answer to the computing power and energy efficiency requirements of artificial intelligence. The transition to liquid cooling opens up new opportunities to further improve performance and ensure stable operation of servers under high loads.

The new liquid-cooled DGX servers are expected to be launched shortly.

Currently, large data centres still predominantly use air cooling for their servers, including the current generation of Nvidia's DGX servers, but with the advent of new technologies and the increased power consumption of new GPUs, such as the upcoming Nvidia Blackwell models, the need for liquid cooling is becoming apparent.

Dell's claims of up to 1000W consumption for Blackwell GPUs, and even mentions of 1400W, really open up a new level of cooling requirements. With these figures, it's already difficult to provide effective air cooling. Processors with 2000W of power could become a reality.
