9 Custom Cooling Fan Options for Dell EMC PowerEdge Servers
How options can be combined with MFS and Offset set simultaneously
If Low Offset and 40% MFS are applied, Fan Speed follows the red dotted line based on Inlet Ambient.
2.4 Maximum exhaust temperature limit
This option allows the system fans speeds to be regulated to prevent the system exhaust air temperature
from exceeding the chosen threshold. Two important things to note regarding this option:
• Maintaining the wanted exhaust temperature cannot be guaranteed under all conditions. For
example, if a system with a rich configuration of components is operating under full utilization and in a
high ambient temperature environment, the system might not have enough cooling headroom to
maintain a low exhaust temperature. The default value is 70°C (158°F) and is maintained under all
conditions.
• It is also possible that there may not be any changes to fan speed because of this setting if the
system configuration, inlet ambient conditions, and server workload do not result in higher exhaust
ambient temperatures than the wanted setting.
