Lenovo announces hybrid liquid-cooling system: Neptune

Water cooling for enterprise servers is slowly creeping in from the fringes to the mainstream of data center use as vendors and end users alike realize the limitations of air cooling. With increased compute density, fans just don’t cut it anymore, and water cooling is far more efficient.

Several vendors have adapted their cabinets to accommodate water-cooling systems, and now Lenovo is the latest to get religion on the subject with Neptune, a series of technologies for the data center. The company announced the new system at the International Supercomputing Conference (ISC) in Frankfurt, Germany.
