Acoustic modes
ThinkEdge SE450 supports three acoustic modes with different acoustic performance.
Disabled: The server operates at default fan speeds.
Mode 1: The server operates with sound pressure level of 45 dBA at 25°C or lower ambient temperature with proper configuration.
Mode 2: The server operates with sound pressure level of 40 dBA at 25°C or lower ambient temperature with proper configuration.
To change the acoustic mode, enter the Setup Utility and go to System settings > Operating Modes > Acoustic mode.
The acoustic modes are designed to run with an ambient temperature of no more than 35°C. Above 35°C, the acoustic mode will be exited to prevent the system from overheating. Once the ambient temperature returns to below 35°C, the acoustic mode will be re-enabled automatically.
Throttling might momentarily occur when acoustic mode is enabled.
See the following information for the components that are recommended in the acoustic modes.
Note
When one of the components listed as "not recommended" is installed, system fan speed will impact acoustic performance. However, if the not-recommended component is lightly loaded, it may still be possible to run the server in the acoustic mode and lower the system noise.
