At GITEX 2025, Hewlett Packard Enterprise (HPE) is highlighting its Cray supercomputing systems, which feature a fully fanless direct liquid cooling architecture. This technology is currently powering El Capitan, the world’s most powerful supercomputer.
HPE’s liquid cooling innovation has played a key role in delivering several systems ranked on the Green500 list, which evaluates the most energy-efficient supercomputers globally.
As artificial intelligence (AI) adoption continues to grow, so does the power demand of next-generation accelerators. According to HPE, traditional air-based cooling methods are becoming less effective for handling these intensive workloads.
The direct liquid cooling approach developed by HPE is designed to improve energy efficiency and reduce operational costs in large-scale AI deployments. It also supports higher server cabinet density while using only half the physical space of traditional systems.
The company notes that this cooling method reduces utility consumption, carbon emissions, and data center fan noise, offering a practical solution for organizations running AI at scale.
