Dell PowerEdge VRTX Acoustics and Thermals Executive summary Thermals and acoustics are key design areas of the Dell™ PowerEdge™ VRTX. Although delivery to the acoustical sensitivity of an open office layout is the primary focus of this white paper, several other thermal and acoustical design features are also discussed.

Dell PowerEdge VRTX Acoustics and Thermals • TurboBoost mode: Acoustical levels can be kept low during operating modes when TurboBoost mode is turned off (in BIOS) for the processor. Operating modes can increase ~5 dBA (~50% louder) when TurboBoost mode is turned on. • HDDs: Are a distant second in noise generation. However, the following will further reduce the acoustical signature after the above has been pursued. Spindle speed of HDDs is most closely tied with noise.

Dell PowerEdge VRTX Acoustics and Thermals cooling is needed. Examples of this situation include high levels of server utilization or stress and high ambient temperatures. Fan offset options The PowerEdge VRTX system supports six hot-swappable cooling fans that provide cooling to the storage and I/O components within the enclosure. The fan offset option allows the user to increase airflow delivery to those components when required.
Dell PowerEdge VRTX Acoustics and Thermals Conclusion Dell PowerEdge VRTX is designed for open-office layout acoustics. Several design features, however, allow its acoustics and cooling to be modulated for specific use cases and particular environments. Options provided to users include an Enhanced Acoustics option, configurations, Enhanced Cooling Mode, and fan offsets. Their use and resultant values are described in this white paper.
