NVIDIA data center hardware is being cooled with water 'hotter than a hot tub'
NVIDIA is reshaping data center cooling with its latest Rubin architecture, utilizing liquid coolant at temperatures exceeding typical benchmarks. The technology absorbs the heat efficiently, allowing for significant reductions in energy and water usage, as well as decreasing noise levels associated with traditional cooling methods. This innovation could pave the way for quieter and more sustainable data centers, although existing facilities may not directly benefit from these advances.
