Neptune™ enables performance without compromise.

Boost AI and HPC performance with Lenovo Neptune™ Liquid Cooling.

The Lenovo difference.

With over a decade of liquid-cooling expertise and more than 40 patents, Lenovo leverages its experience in large-scale supercomputing and AI to help organisations deploy high-performance AI at any scale.

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 the mainstream ThinkSystem portfolio.
Liquid-assisted cooling for the benefits of liquid in an air-cooled system.
Rack-level rear door water cooling.

Lenovo Neptune^TM enables performance without compromise.

Solutions

Meet Lenovo’s Neptune cooling technologies

Rack water cooling

Keep heat down in the rack with either a rear-door heat exchanger (RDHX) or in-rack cooling distribution units (CDU).

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

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.

Energy Aware Runtime & XClarity software

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