A100 based on the GA100 AMPERE graphic processor is the precursor of the accelerator of the H100 Hopper data processing centers. The new option with liquid cooling is based on the A100 PCIE model, released in June last year. This is not an option for SXM, which is used for HGX/DGX A100 systems.
Although there is nothing unusual in liquid cooling in the graphic processor for the data processing center, this model seems to be a smooth NVIDIA design with tubes on the rear panel, next to an 8-pin power connector.
It should be noted that liquid cooling for A100 accelerators is already widespread, except that it requires manual replacement of a passive two -slope cooler. Passive cooling may not be ideal for workstation systems, where a sufficient air flow is required. This is probably why NVIDIA chose the A100 SXM option for its DGX A100 station, using complex cooling with a refrigerant.
