# A simple script to control fan speeds on Dell generation 12 PowerEdge servers.
# If the inlet temperature is above $TEMP_THRESHOLD C enable iDRAC dynamic control and exit program.
# If inlet temp is below $TEMP_THRESHOLD C set fan control to manual and set fan speed to predetermined value.
# The tower servers T320, T420 & T620 inlet temperature sensor is after the HDDs so temperature will
# be higher than the ambient temperature.
