41 PowerEdge 14th generation (14G) acoustical performance and dependencies | Document ID | version (optional)
14 PowerEdge FC640 acoustics
Dell EMC PowerEdge FC640 is a blade server appropriate for data center environment.
Table 14 summarizes the sound power, sound pressure level, and prominent tone performance of the FC640
in a 23±2°C environment.
Acoustical performance
To capture the breadth of potential customer specifications and deployments, the FC640 has been tested in
FX chassis with different configurations. Table 14 summarizes the configuration and acoustical performance
of the PE FC640. Each configuration has been tested according to Dell EMC acoustical standards for rack-
mounted servers.
PowerEdge FC640 acoustical dependencies
 Ambient Temperature. For a similar workload fan speeds (and thus, acoustical noise) may increase
as ambient temperature increases. Please note there is ambient temperature restriction for FC640,
defined in DPN: 2P9GM.
 High Wattage CPU. High-power (TDP) CPU cards may result in higher acoustical noise output.
 NVMe SSD. NVMe SSD consumes more power than other SATA/ SAS drives. It requires higher fan
speeds for cooling, and thus increased acoustical output is expected.
 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.
