Sorry for my self talk but I solved my problem. To run am mix of 5V and 24V fans i used the following solution.
- Set the "V FAN" jumper to the V_FAN;VIN position
- Connect the 24V fans normaly
- Connect the black alias ground wire to the minus pin of the chosen fan port
!Do not connect the red alias puls wire to the fan port, with great probability you will destroy our fan and/or the board - Connect the red wire instead to the free 5V pin of the before described "V FAN" pinout area
Now you are able to control all fans from full power to switch off
Maybe a mod can take my description and put it into the wiki, maybe its more easy to find there
