Dell PowerEdge M610 Manual técnico
Thermal control also detects and responds to hardware configuration. Thermal management
adjusts cooling according to what the system really needs, and draws lower fan power draw and
generates lower acoustical noise levels than those without such controls.
Environmental specifications: The optimized thermal management makes the PowerEdge M520
reliable under a wide range of operating environments as shown in Table 23. When operating
above 30°C ambient, performance impacts may be seen. For more information see the
PowerEdge M520 Systems Owner's Manual
The acoustical performance of the PowerEdge M520 is reflected in Table 15. The addition of some
components can cause an increase in fan speed and acoustical output. Contributors to acoustical
output can include:
The system thermal profile selected in BIOS (for example, Power optimized DAPC or
Performance optimized)
Number of installed processors
Population of modular, non-homogenous modular deployment
Impedance of blanks
