Internal Front Fan (Control Settings)

Some PCI Express cards produce substantial heat and must be cooled properly to eliminate over heating problem.
One Fan is located in the front of the enclosure to provide cooling required for the hottest PCI Express Cards. Some
graphics cards GPU's require these fans to be at full capacity to prevent over-heating.
As safety measure, Magma provides ROBEN-3 with the fan functioning at full speed (MAX). However, noise is a
concern for many applications. For noise sensitive applications, we have provided this Thermistor setting (THERM) to
help alleviate fan noise in situations when a low heat producing card is installed in Magma Roben-3.
By default, the fan will run at maximum speed when the DIP Switch is to MAX that control fan speed. When setting
to Thermistor (THERM), the fan speed is controlled by the temperature inside the enclosure. Thermally controlled
fans will run at maximum speed when the Thermistor senses temperature at or above an upper limit. Fans will run
at minimum speed if the temperature is at or below lower limit.
To set the FAN (speed) locate the red DIP switch SW500 on the expansion board. MAX = Fan runs at fast mode.
THERM = Fan is set to Thermistor controlled.
The DIP switch SW500 controls the front fan of the Roben 3 expansion unit.
