Neptune™ enables performance without compromise

Smarter doesn’t sacrifice energy efficiency for higher performance. Lenovo has led the world in liquid cooling technology for more than a decade.


System overheating issues cause shutdowns, slower performance, and data loss if allowed to accumulate. Lenovo Neptune™ tackles this problem by using liquid to remove heat, which is much more efficient than traditional air cooling.

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

  • Rack rear door water cooling
  • Direct water cooling to each node
  • Liquid-assisted cooling for the benefits of liquid in an air-cooled system
  • Energy Aware Runtime (EAR) and XClarity Energy Manager software to optimize performance and power

Why choose Lenovo for liquid cooling technology?

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).
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.
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.
