Lenovo is pushing its Neptune direct water-cooling across more servers to cut data center power by about 40 percent versus air cooling while supporting dense CPU/GPU AI and HPC racks.
The warm-water design (up to ~45 °C) removes chillers, enables PUE near 1.1, and targets regions like APAC where AI-driven electricity demand is set to more than double by 2030.
Lenovo is doubling down on liquid-cooled, AI-ready infrastructure as a practical path to higher GPU density and lower operating cost, making the source worth a full scan for data center planners.
