Question Case cable confusion assistance please

[finwizz]

Using a be quiet dark base 900 pro rev 2 case with Asus Rog Strix X570-E motherboard.

The case has a cable from the PCB Panel Box at the back of the case (runs LCD, fans etc) and has a cable coming off it which has, what looks like, a 4 pin "fan connector". The manual states " PWM connector to the motherboard". I am confused as to where on the motherboard this one goes. I have a CHA_Fan1, CHA_Fan2 and an extra CPU Fan connector. Does it connect to one of these please?

There is also a spare motherboard AIO pump connector which I am not using.

Yes you would connect to Fan1 or Fan2. The pump connector is probably a constant voltage so you don't want to use that. If you want the LEDs to change with the CPU temp, you could probably use the extra CPU fan connector. I would probably use the one that is closest.
