New fanless cooling technology enhances energy efficiency for AI workloads by achieving a 90% reduction in cooling power consumption

• New HPE fanless cooler cuts server blade power consumption by 37%
• The system uses direct liquid cooling, perfect for AI technologies
• The architecture is designed to be scalable dependent on business needs

Hewlett-Packard Enterprise (HPE) recently hosted its AI Day 2024 event, introducing the industry’s first 100% fanless direct liquid cooling architecture.

As artificial intelligence (AI) technologies continue to evolve, power consumption in next-generation accelerators has increased, surpassing the capabilities of traditional air-cooling methods.

Organizations running large-scale AI workloads are now searching for more efficient solutions to manage their infrastructure’s energy demands, and hPE has pioneered direct liquid cooling technology, which has become one of the most effective methods for cooling high-performance AI systems. This approach has allowed HPE to deliver seven of the top 10 most energy-efficient supercomputers on the Green500 list.

100% fanless direct liquid cooling addresses cooling challenges in AI systems

The new cooling system is designed to improve efficiency in several key areas, with HPE saying the fanless architecture reduces cooling power consumption by 90% compared to traditional air-cooling systems and offers significant environmental and financial advantages.

The system is built on four core elements. First, the system uses a comprehensive cooling design featuring an 8-element system that cools the GPU, CPU, server blade, local storage, network fabric, rack, cluster, and coolant distribution unit (CDU).

The second element is that the fanless cooler also offers high-density performance that supports compact configurations backed by rigorous…
