Description
The Lenovo ThinkSystem SR650 V4 Compute Complex Neptune Core Module is a direct water-cooling (DWC) upgrade that liquid-cools the processors, memory, and voltage regulators of the SR650 V4 server as a combined "compute complex." Using an open-loop water cooling design connected to a coolant distribution unit, the module is capable of removing more than 80% of the heat generated by these components directly from the server, resulting in significant power savings at the data center level.
This module is well suited for SR650 V4 deployments that prioritize thermal efficiency and reduced operating costs, allowing server fans and facility cooling systems to handle a smaller share of the overall thermal load.
