to run fan only when internal temperature in the drive is in the range 35 °C (95 °F) to ap-
proximately 55 °C (131 °F). The fan runs at low speed below 35 °C (95 °F), and at full speed at approxi-
mately 55 °C (131 °F).
[1]
On 50%
The fan always runs at 50% speed or above. The fan runs at 50% speed at 35 °C (95 °F), and at full speed at
approximately 55 °C (131 °F).
[2]
On 75%
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).
[3]
On 100%
The fan always runs at 100% speed.

Auto (Low
temp env.)
This option is the same as
[0] Auto
, but with special considerations around and below 0 °C (32 °F). In op-
tion
[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
.
