PowerEdge R240 acoustics
Dell EMC PowerEdge R240 is a rack-mount server appropriate for attended data center environment. However, lower acoustical
output is attainable with proper hardware or software configurations. For example, the minimum configuration of PowerEdge R240 is
quiet enough for typical office environment. The list below are the PowerEdge R240's acoustical dependencies:
• Ambient Temperature : For a similar workload fan speeds (and thus, acoustical noise) may increase as ambient temperature
increases.
• High Wattage CPU : High-power (TDP) CPU parts may result in higher acoustical noise output.
• Rear Drives : When rear drives are installed in R340, fan speed may increase for cooling the drives, and hence both idle and
operating acoustical outputs may be higher.
• System Thermal Profile Selected in BIOS : The default setting is “Power Optimized (DAPC)”, which generally means lower fan
speed and acoustics. If “Performance Optimized” is selected, fan speed and acoustical noise may increase.
The PowerEdge R240 acoustical performance is characterized for 3 configurations: Minimum, Typical and Feature Rich. The
following tables summarizes the configuration and acoustical performance of the PowerEdge R240. Each configuration has been
tested according to Dell EMC acoustical standards for rack-mounted servers.
