I'm trying to add a second cooling fan to my ants (push-pull)
I have some coolmaster jetflow 120 fans (12V 0,4A), but when plug-ins them in in the free 4pin connector on the secon board nothing happens, do I have to enabled the second fan somehow or am I doping something wrong?

Likely doing something wrong, but I haven't tried it with a 4-pin setup.  

What wire is on top?  If done correctly it should be:
Black (top)
Red
Yellow
Blue (bottom)

All black wires(what ever happend to colorcoding these days...)

On the fan it says:

+black
-black
FG black
PWM black

PWM should be on the bottom.  If disconnected, it will run the fan at full speed.  If connected, the fan speed is determined by the firmware.
