The server has the following acoustic noise emissions declaration:
  • Sound power level (LWAd)
    • Idling:
      • Min: 5.4 Bel
      • Typical: 5.4 Bel
      • Max: 5.5 Bel
    • Operating:
      • Min: 5.7 Bel

Note
  • These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296. The operating profile is represented by 80% CPU TDP or 70%/30% storage read/write or 100% GPU workload.
  • The declared acoustic sound levels are based on the specified configurations, which may change depending on configuration/conditions.
    • Min: 1x 80W CPU, 2x 16GB RDIMMs, 1GbE I/O module board, 1 x NVMe M.2 boot drive , 2x SATA SSDs, 2x NVMe M.2 data drives, DC power module board (PMB), no dust filter, rear-to-front fan direction
    • Typical: 1x 80W CPU, 4x 16GB RDIMMs, 10/25GbE I/O module board, 1 x NVMe M.2 boot drive, 1x NVIDIA A2 GPU, 4x NVMe M.2 data drives, no dust filter, DC power module board (PMB), rear-to-front fan direction

  • Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employee's location in relation to the equipment. Further, compliance with such government regulations depends on a variety of additional factors, including the duration of employees' exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations.
Acoustic modes

ThinkEdge SE360 V2 supports three acoustic modes with different acoustic performance.

  • Disabled: The server operates at default fan speeds.

  • Mode 1: The operation of system fans is optimized to lower the overall noise level of the server.

    • Mode 1 supports ambient temperature lower than 35°C.

    • In Mode 1, the server operates with sound pressure level of 50 dBA at 25°C.

    • Performance degradation may occur at heavy workloads.

  • Mode 2: The operation of system fans is optimized to lower the overall noise level of the server further than Mode 1.

    • Mode 2 supports configurations with 4-core or 8-core processor at ambient temperature lower than 35°C.

    • In Mode 2, the server operates with sound pressure level of 45 dBA at 25°C.

    • Performance degradation may occur at heavy workloads.

To change the acoustic mode, enter the Setup Utility and go to System settings > Operating Modes > Acoustic mode.
