14 PowerEdge 14th generation (14G) acoustical performance and dependencies | Document ID | version (optional)
4 PowerEdge T340 acoustics
Dell EMC PowerEdge T340 is a tower server appropriate for typical environment. However, lower acoustical
output is attainable with proper hardware or software configurations. For example, the minimum configuration
of T340 is quiet enough for a quieter office environment.
T340 Acoustical performance data
Acoustical performance for two configurations are provided: typical and feature rich. Table 5 contains a
summary of the configuration and acoustical performance of the PE T340. Each configuration has been
tested according to Dell EMC acoustical standards for tower servers.
PowerEdge T340 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.
 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.
Methods to reduce acoustical output of the T340
Although the T340 is designed for use in typical office environment, some users may prefer a quieter output.
Dell EMC suggests the following. It is important to note that in most cases, the baseline idle fan speed of the
system cannot be lowered without changing the configuration of the system, and in some cases, even a
configuration change may not reduce idle fan speeds.
 Reduce Ambient Temperature. Lowering the ambient temperature allows the system to cool
components more efficiently than at higher ambient temperatures.
 Optimize Third Party PCI Card Options.
 Replace Third Party PCI Cards with similar Dell Supported Temperature PCI Controlled Cards, if
available. Dell EMC works diligently with card vendors to validate and develop PCI cards to meet Dell
EMC’s exacting standards for thermal performance.
 HDD Quantity. An incremental reduction in acoustical output may be gained by reducing the quantity
of HDDs.
