The world of technology observed a spate of some marvels last week at the GITEX 2025, and one of the most notable innovations showcased there was Hewlett Packard Enterprise's (HPE) Cray supercomputing systems, believed to be the primary equipment for the world's fastest supercomputers.
The system features a unique 100% fanless direct liquid cooling architecture and will power some of the world's most powerful supercomputers, including El Capitan.
The incredible side of the story is that this innovative cooling method has been the key component in helping HPE develop several top-performing supercomputers on the Green500 list, which ranks the most energy-efficient systems globally.
While modern-day next-generation accelerators have substantially improved efficiency, the rising use of artificial intelligence (AI) has reportedly led to increased power consumption.
The world-class cooling system comes amid a surge in power demand, which is now more than the limits of traditional cooling methods, and organisations managing large AI workloads are required to adopt more efficient operational strategies.
Given that, HPE is leading the industry with its direct liquid cooling solutions, recognised as the most effective way to cool advanced AI systems.
The 100% fanless direct liquid cooling architecture improves energy and cost efficiency for AI deployments operating at large scale, while reducing cooling power requirements, lowering utility costs, cutting carbon emissions, and minimising data centre noise.
