Lenovo Neptune Powers the World's Greenest and Most Efficient HPC & AI Systems, Delivering up to 40% Lower Energy Use

• Lenovo ranks #1 on the Top500 Supercomputers and Green500 lists
• Neptune systems deliver up to 100% heat removal achieving 1.1 PUE
• Warm-water cooling operates up to ~45 °C, eliminating chilled-water requirements

SYDNEY, Nov. 27, 2025 /PRNewswire/ -- Lenovo today announced expansion of its Neptune liquid cooling technology across its data center portfolio, advancing sustainable infrastructure for the age of AI. Designed to address the rising compute and energy demands of modern data centers, Lenovo Neptune enables servers to operate with about 40% lower power than air-cooled systems, ensuring consistent performance while lowering environmental impact.

Lenovo continues to strengthen its leadership in energy-efficient computing. As of November 2025, Lenovo ranks #1 on both the Top500 and Green500 lists, powered significantly by Neptune-enabled supercomputers that deliver world-class performance with industry-leading sustainability.

A Cooling Approach for the AI Era

The IDC & Lenovo CIO Playbook 2025 highlights improving sustainability as a top business priority. As organizations accelerate AI adoption, data centers are facing unprecedented thermal and performance pressures due to soaring compute density and energy use. Traditional air cooling is no longer sufficient to manage the heat generated by modern AI systems.

Lenovo's Neptune Direct Water-Cooling (DWC) technology addresses these challenges by circulating warm water directly to system nodes to remove heat from CPUs, GPUs, and memory. Unlike chilled-water systems that operate at around 18 °C, Neptune allows coolant temperatures up to ~45 °C, eliminating chiller requirements, reducing reliance on air-handling units, and ensuring a stable thermal envelope for AI and HPC workloads.

Built on more than a decade of innovation and hundreds of patents, the sixth-generation Neptune systems feature advanced water-based cooling architectures designed to support higher rack densities and enable efficient operations without specialized air conditioning. The new vertical liquid-cooling chassis delivers accelerated computing in a compact, 100% liquid-cooled system, eliminating the need for power-hungry fans and lowering energy use across the data center.
