    • Features and Benefits

      Lenovo Neptune™ technology

      The ThinkSystem SD665 V3 with Lenovo Neptune Direct liquid cooling 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.

      Lenovo Neptune™ technology

      Greater performance, density

      The ThinkSystem SD665 V3 is powered by dual 4th Generation AMD EPYC™ Processors. Because of Neptune™ liquid cooling technology, it can run CPUs up to 400W in a compact, 1/2U form-factor, compared to 165-205W CPUs for air-cooled 1/2U systems. A single rack of ThinkSystem SD665 V3 servers can deliver more than half a Petaflop of HPC compute power without using accelerators.

      Greater performance, density

      Quiet efficiency

      Because water cooling keeps the components cooler, the ThinkSystem SD665 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.
