Little update:
Because I wasn't able to controll my four case fans with an external fan controllor (clatter noise) I ordered a PWM signal splitter.
My case fans are all PWM controlled, that means that you can't controll them by reducing the voltage. PWM fans always need 12V and get a pulsed signal from the 4th pin on the mainboard.
Because my mainboard only has one real PWM port (CPU_FAN) I had to use a splitter, which is forwarding the signal to multiple fans.
So yesterday I installed a "Akasa FLEXA FP5". This cable gets the 12V directly from the power supply and forwards the PWM signal to 5 fans. Now my mainbaord can controll the CPU and all four case fans.
In the BIOS I set the PWM controll to a very low signal increase by increasing CPU temperature.
