Description
The fan always runs at 75% speed or above. The fan runs at 75%
speed at 35 °C (95 °F), and at full speed at approximately 55 °C
(131 °F).
The fan always runs at 100% speed.
This option is the same as [0] Auto, but with special
considerations around and below 0 °C (32 °F). In option [0] Auto
there is a risk that the fan starts running around 0 °C as the drive
detects a sensor fault and thus protects the drive while reporting
warning 66, Heat sink Temperature Low. Option [4] Auto (Low temp
env.) can be used in very cold environments and prevents the
negative effects of this further cooling and avoids warning 66,
Heat sink Temperature Low.
