Okay, chose the ignore feature in the main bios. Shut it all down and disconnected the fans, re-connected to the CHA_Fan2 and rebooted. Immediate cpu error on the fan connector. So shut it all down and re-connected back to the cpu terminal. pretty annoying since I'd like to drive that particular set of fans with using the TC in the coolant loop. I guess the other option would be to connect the case fans at the back to the cpu since they are running at a static speed and not pwm.
