Lenovo Neptune™ technology

The ThinkSystem SD650 V3 with Lenovo Neptune™ Direct Water Cooling (DWC) technology utilizes warm-water cooling (up to 50⁰C) to remove heat from the CPUs, memory, I/O, local storage, and voltage regulators. Because water provides superior heat removal compared to air, the critical components all operate at lower temperatures, delivering greater performance and density in quiet, energy efficient system.

Greater performance, density

The ThinkSystem SD650 V3 is powered by dual 5th Gen Intel® Xeon®Platinum processor CPUs. Because of Neptune™ liquid cooling technology, it can run CPUs up to 385W in a compact, 1/2U form-factor, compared to 165-205W CPUs for air-cooled 1/2U systems. A single rack of ThinkSystem SD650 V3 servers can deliver more than half a Petaflop of HPC compute power without using accelerators.

Quiet efficiency

Because water cooling keeps the components cooler, the ThinkSystem SD650 V3 does not have fans, which are a major consumer of energy. Customers who have implemented Neptune™ DWC systems have estimated up to 40% savings on energy costs from hardware and software optimization. Removing the system fans eliminates the fan noise, providing nearly silent operation.
