Acoustical noise emissions
The server has the following acoustic noise emissions declaration:
• Sound power level (L
WAd
– Idling: 4.6 Bel (Typical), 5.1 Bel (Max.)
– Operating 1: 4.6 Bel (Typical), 5.1 Bel (Max.)
– Operating 2: 4.8 Bel (Typical), 5.1 Bel (Max.)
• Sound pressure level (L
– Idling: 30.5 dBA (Typical), 35.9 dBA (Max.)
– Operating 1: 30.5 dBA (Typical), 35.9 dBA (Max.)
– Operating 2: 33.2 dBA (Typical), 35.9 dBA (Max.)
Notes:
• These sound levels were measured in controlled acoustical environments according to procedures specified by
ISO7779 and are reported in accordance with ISO 9296.
• Idle mode is the steady state in which the server is powered on but not operating any intended function. Operating
mode 1 is 70% CPU TDP. Operating mode 2 is 100% CPU TDP.
• The declared acoustic sound levels are based on the following configurations, which may change depending on
configuration/conditions.
– Typical: 1x 80W CPU, 1x 16GB DIMM, 2x HDD, 1x 800W GW PSU
– Max: 1x 95W CPU, 2x 32GB DIMM, 2x HDD , 1x 9350-8i RAID,1x 10G NIC, 2x 800W GW PSU
• 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.
Ambient temperature management
Adjust ambient temperature when specific configuration is applied:
• Keep ambient temperature to 45°C or lower when a 60W (or lower) TDP CPU and an 80W heat sink are installed.
• Keep ambient temperature to 40°C or lower when a 70W (or lower) TDP CPU and an 80W heat sink are installed.
• Keep ambient temperature to 35°C or lower when one of the following is installed:
– 95W (or lower) TDP CPU and a 95W heat sink.
– 80W (or lower) TDP CPU and an 80W heat sink.
– GPUs, M.2 drives (480GB or below), U.2 drives, U.3 drives, and 25GbE Ethernet adapters.
• Keep ambient temperature to 30°C or lower when an M.2 drive 960GB is installed.
