HPE Unveils the World’s Fastest Supercomputer at GITEX 2025

At GITEX 2025, Hewlett Packard Enterprise (HPE) is turning heads with the showcase of its Cray supercomputing systems, which feature a groundbreaking 100% fanless direct liquid cooling architecture.

This cutting-edge technology powers some of the world’s fastest and most efficient systems, including the renowned El Capitan supercomputer.

It has also played a pivotal role in helping HPE secure top positions on the Green500 list, which ranks the globe’s most energy-efficient supercomputers.

While next-generation accelerators have enhanced performance and efficiency, the rapid rise of AI workloads has led to a surge in power consumption outpacing the limits of traditional cooling systems.

As a result, organizations handling large-scale AI operations are being pushed to adopt smarter, more sustainable infrastructure strategies.

Positioning itself at the forefront of this transformation, HPE continues to lead the industry with its direct liquid cooling technology, recognized as one of the most effective and energy-efficient cooling methods for advanced, next-gen AI systems.

The 100% fanless direct liquid cooling system architecture significantly improves the energy and cost efficiency of large-scale AI deployments.

This leads to substantial reductions in cooling power, utility costs, carbon emissions, and data center fan noise.

Additionally, systems utilizing this architecture can support higher server cabinet density, requiring only half the floor space.
