- Lenovo ranks #1 on the Top500 Supercomputers and Green500 lists
- Neptune programs ship as much as 100% warmth elimination reaching 1.1 PUE
- Heat-water cooling operates as much as ~45 °C, eliminating chilled-water necessities
SYDNEY, Nov. 27, 2025 /PRNewswire/ — Lenovo right now introduced growth of its Neptune liquid cooling expertise throughout its knowledge middle portfolio, advancing sustainable infrastructure for the age of AI. Designed to deal with the rising compute and vitality calls for of contemporary knowledge facilities, Lenovo Neptune permits servers to function with about 40% decrease energy than air-cooled programs, guaranteeing constant efficiency whereas decreasing environmental influence.
Lenovo continues to strengthen its management in energy-efficient computing. As of November 2025, Lenovo ranks #1 on each the Top500 and Green500 lists, powered considerably by Neptune-enabled supercomputers that ship world-class efficiency with industry-leading sustainability.
A Cooling Strategy for the AI Period
The IDC & Lenovo CIO Playbook 2025 highlights bettering sustainability as a prime enterprise precedence. As organizations speed up AI adoption, knowledge facilities are dealing with unprecedented thermal and efficiency pressures attributable to hovering compute density and vitality use. Conventional air cooling is not adequate to handle the warmth generated by fashionable AI programs.
Lenovo’s Neptune Direct Water-Cooling (DWC) expertise addresses these challenges by circulating heat water on to system nodes to take away warmth from CPUs, GPUs, and reminiscence. Not like chilled-water programs that function at round 18 °C, Neptune permits coolant temperatures as much as ~45 °C, eliminating chiller necessities, decreasing reliance on air-handling items, and guaranteeing a steady thermal envelope for AI and HPC workloads.
Constructed on greater than a decade of innovation and lots of of patents, the sixth-generation Neptune programs characteristic superior water-based cooling architectures designed to assist increased rack densities and allow environment friendly operations with out specialised air con. The brand new vertical liquid-cooling chassis delivers accelerated computing in a compact, 100% liquid-cooled system, eliminating the necessity for power-hungry followers and decreasing vitality use throughout the information middle.
Advancing Lenovo’s Web-Zero Imaginative and prescient
Lenovo is progressing on its mission to attain net-zero carbon emission by 2050 (validated by Science Based mostly Targets initiative (SBTi)), advancing long-term emissions discount via renewable vitality adoption, environment friendly product design, and extra sustainable knowledge middle operations. Neptune expertise is integral to this journey, providing tangible reductions in knowledge middle energy consumption and enabling prospects to progress towards their sustainability objectives with out compromising on AI efficiency.
Assembly World Demand for Sustainable Knowledge Infrastructure
Pushed by hovering demand for AI, cloud, and superior digital companies, knowledge facilities throughout Asia Pacific are increasing quickly – and so is their want for energy. Electrical energy consumption within the area is predicted to rise from 320 terawatt-hours in 2024 to 780 terawatt-hours by 2030.
“Throughout Asia Pacific, organizations are on the lookout for AI infrastructure that isn’t solely highly effective but additionally basically extra vitality environment friendly. Neptune provides our prospects that benefit. Our management on the Top500 and Green500 rankings demonstrates the real-world influence of those improvements. As AI scales, options that mix efficiency with accountable vitality use will outline the subsequent period of digital development, and that’s precisely what Lenovo is delivering,” stated Kumar Mitra, Government Director, Lenovo Infrastructure Options Group (ISG), Central Asia Pacific and Australia & New Zealand.
Sustainable Efficiency at Scale
Lenovo continues to advance sustainable AI-ready infrastructure via its Neptune ecosystem, which integrates Direct-to-Node warm-water cooling, Rear Door Warmth Exchangers, and Thermal Switch Modules right into a extremely environment friendly, closed-loop design. Heat coolant flows via precision chilly plates on key parts, rising by about 10–15 °C earlier than transferring warmth via a separate facility loop for reuse, eradicating the necessity for chilled water whereas sustaining steady efficiency. Mixed with Lenovo’s ThinkSystem and ThinkAgile servers, Neptune helps prospects decrease energy consumption and TCO whereas supporting dependable, high-density AI and HPC workloads.
Lenovo’s ThinkSystem SR780a powered by Lenovo Neptune, reveals how warm-water cooling delivers actual effectivity advantages. The system has achieved a Energy Utilization Effectiveness (PUE) of 1.1, a milestone in knowledge middle effectivity. PUE signifies how a lot of energy is used for computing versus cooling. An ideal rating is 1.0. A PUE of 1.1 means 0.1 watts are spent on cooling, a degree that could be very troublesome to attain with air-cooled programs.
Lenovo is already driving measurable influence for a few of the world’s most demanding workloads. For instance, at DreamWorks Animation, Neptune-powered HPC programs delivered a 20% enhance in efficiency whereas decreasing cooling necessities. The expertise can also be trusted throughout Asia Pacific by main meteorological businesses in Korea and Malaysia, in addition to universities, analysis organizations, and digital content material creators. Its broad adoption underscores Neptune’s skill to assist various, high-density AI and HPC workloads effectively and reliably.
The expertise is already deployed in a number of of the world’s most energy-efficient supercomputers, reinforcing Lenovo’s place as a frontrunner in accountable computing. Neptune is a key enabler of Lenovo’s broader aim of serving to prospects construct AI-ready infrastructure that’s each highly effective and environmentally accountable.
