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.
