on the implemented fan. If the fan generates a speedometer-signal this
value represents the minimum rpm (percentage-value) of the determined
maximum rpm. If the fan does not generate a speedometer signal, this
value defines the minimum output power in percent. If you use a fan
without a speedometer signal you should determine the minimum value,
via the “manual regulation”, at which the fan is guaranteed to start and
use this value as the “minimal output” for the fan. Default value is 35 %.

Allows the switching between a linear and a progressive speed-curve in
the temperature-controlled operation or activates regulation via a tar-
get-temperature.
"Linear" and "progressive": linear means that the fan is regulated propor-
tionally between the start-up temperature and the full load temperature,
while at progressive regulation the speed-curve is dependent on the
temperature. With climbing temperatures the speed-curve begins shal-
low but climbs steeper as the full load temperature is reached.
Opposite to the linear regulation, the fan performance in progressive
regulation is mobilized only in the upper temperature area and a quieter
operating sound is made possible at a lower heat load. However at
higher temperatures the full load of the fans is still reached rather
quickly.
Sensor parameters used: "start-up threshold", "full load threshold" and
"hysteresis"
"Fixed": the fan is regulated so that the target temperature is held con-
stant if possible. For this purpose the sensor parameter "target tempera-
ture" is used.
Sensor parameters used: "start-up threshold", "full load threshold", “con-
troller delay”, “controller factor” and "hysteresis"

Here you can adjust whether the fan is regulated via the rpm-signal
(„active“) or via the output power („inactive“).
When connecting a fan to the external fan connector of the PC interface
board, please note that not all fans generate a rpm signal and deacti-
vate this option if the fan does not provide a rpm signal. With some fans
