Amazon Web Services Unveils Custom Cooling Solution for Next-Gen Nvidia GPUs in AI Infrastructure

AWS Innovates to Cool Next-Gen AI Hardware

Amazon Web Services (AWS) has unveiled a groundbreaking solution to address the cooling challenges posed by the latest generation of NVIDIA GPUs used in artificial intelligence workloads. The company's custom-designed In-Row Heat Exchanger (IRHX) represents a significant advancement in managing the thermal output of high-density GPU configurations 1

As the AI boom accelerates, the demand for more powerful GPUs has led to increased energy consumption and heat generation. NVIDIA's latest GPUs, particularly the GB200 NVL72 system which packs 72 Blackwell GPUs into a single rack, require innovative cooling solutions beyond traditional air cooling methods 1

Dave Brown, VP of Compute and Machine Learning Services at AWS, explained that commercially available cooling equipment was insufficient for their needs:

"They would take up too much data center floor space or increase water usage substantially. And while some of these solutions could work for lower volumes at other providers, they simply wouldn't be enough liquid-cooling capacity to support our scale." 1

AWS's Innovative Solution

Rather than constructing entirely new liquid-cooled data centers, which would have been time-consuming and costly, AWS engineers developed the IRHX. This solution can be integrated into both existing and new data centers, providing the necessary cooling capacity without requiring a complete infrastructure overhaul 2
