fan speed signal from only one fan can be monitored, but the other fans run at the same voltage. Such a
configuration is especially useful if many fans need to be connected to a cooling array. For example, three
radiator fans can be connected to one channel. Bundling of radiator fans also comes in very handy if large
radiators such as the Mora or Phobya Nova (9 fans each). The maximum permissible number of connected
fans depends on the power consumption of the fans. Up to 18W of power may be drawn from an individual
channel passiv cooled..We propose to use an aktiv fan. The power consumption of a standard 120mm fan is
approximately 2.5 to 3.6W. Before connecting multiple fans please check the maximum power draw of the
fans. Should the 10W per channel not suffice, an active cooling system of the driver components can
increase the maximum power output up to 38W. Regarding this please consult the appendix.
The last three channels (3-Pin) are unregulated for the pumps / flow sensors, as these are controlled
separately by the software. Theoretically it is also possible to connect a fan, but the channels are unable to
detect it as such, resulting in constant 12V operation of the connected fan. The 3 channels for pumps / flow
sensors aren’t necessarily compatible with the according components. This means that in some cases it is
e.g. necessary to connect a 3-Pin plug to the pump / flow sensor. Please check in advance if the pump is
suitable for the limitations of the Alphacool Heatmaster 2 (18W per channel). On the 3 channels the 12V DC
voltage from the PSU is simply passed through, hence additional voltage adjustments are not possible. If you
wish to control the speed of your pump, this is possible with an analogue adaptor which is connected parallel
to the 6 fan channels. This allows a pump to be connected and controlled in speed e.g. according to a
measured temperature. Such analogue adaptors will be available soon. The following products can be
connected to the pump / flow sensor channels:
