Enclosure Fan Speed Control
123
This hardware setting provides full voltage to the fans for maximum operational
speed, which is greater than the maximum speed set by the automatic software
control. This configuration is normally used when fan speed noises are not an
issue, and the ambient operating temperature is at or above 30°C (86°F), thus
ensuring that maximum available cooling is being provided.

The jumpers JP1 and JP2 are by default are offset which enables the use of the
automatic fan speed control. The jumper JP1 controls Fan 0 and JP2 controls Fan 1.
Placing the included jumper on both pins of each jumper will override the
automatic setting and set the fans to maximum power.
