New 6th-Gen Lenovo Neptune™ Liquid Cooling Powers the Era of AI

Boost AI and HPC performance with Lenovo Neptune™ Liquid Cooling. With over a decade of liquid-cooling expertise and more than 40 patents, we leverage our experience in large-scale supercomputing and AI to help organizations deploy high-performance AI at any scale.

Learn more about how Lenovo is bringing you faster, easier and more powerful Al.

Overview

New high-performance applications using AI technology require more system power than ever, increasing energy demands. Lenovo 6th Generation Neptune™ Liquid Cooling tackles this problem by using liquid to remove heat, which is much more efficient than traditional air cooling and provides maximum performance while dramatically improving energy efficiency.

For customers who need maximum AI and HPC performance but don’t have liquid cooling infrastructure, we partner with leading colocation companies to offer Neptune™-ready infrastructure for private AI workloads.

Lenovo Neptune™ Liquid Cooling is HPCwire’s Best HPC Server Product or Technology for 2023, one of HPCwire’s Top 5 New Products or Technologies to Watch in 2023, CRN’s 2024 Best Green Energy Product of the Year, winner of the 2024 SEAL Sustainable Product Award.

Neptune's holistic approach to liquid cooling goes beyond simply cooling the CPUs. It includes:

  • Direct warm water cooling of entire systems for maximum performance and efficiency, turning waste heat into value by allowing hot water reuse in the facility
  • Direct water cooling of individual system components, available throughout our mainstream ThinkSystem portfolio
  • Liquid-assisted cooling for the benefits of liquid in an air-cooled system
  • Rack-level rear door water cooling
  • Energy Aware Runtime (EAR) and XClarity Energy Manager software to optimize performance and power

Solutions

Meet Lenovo’s Neptune cooling technologies

Direct water cooling

Direct water cooling

With full systems and core systems available, direct water cooling removes heat from key components – including power supplies – for completely fanless operation.
Liquid-assisted cooling

Liquid-assisted cooling

With either a thermal transfer module (TTM) or liquid-to-air heat exchanger (L2A), traditional air-cooled systems benefit from liquid cooling with specially designed heat handling, without added plumbing.
Rack water cooling

Rack water cooling

Keep heat down in the rack with either a rear-door heat exchanger (RDHX) or in-rack cooling distribution units (CDU).
Energy Aware Runtime & XClarity software

Energy Aware Runtime & XClarity software

By optimizing power states, turning off unused components, and routing workloads to the most efficient resources, our software helps deliver optimal performance at a low level of energy consumption.
