43 PowerEdge 14th generation (14G) acoustical performance and dependencies | Document ID | version (optional)
15 PowerEdge C6420 acoustics
Dell EMC PowerEdge C6420 is a rack-mount server appropriate for unattended data center environment.
Table 15 summarizes the sound power, sound pressure level, and prominent tone performance of the C6420
in a 23±2°C environment.
Acoustical performance
The C6420 acoustics has been characterized in two typical configurations. Table 15 summarizes the
configuration and acoustical performance of the PE C6420. Each configuration has been tested according to
Dell EMC acoustical standards for rack-mounted servers.
PowerEdge C6420 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 C6420,
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.
