Question Case fans not spinning and RGB not lighting up at all

[Finnlovesrocks]

So my CPU fans seem to work fine, but none of my CHA fans (I guess those are the 4 case fans, sorry completely new to building) are spinning. The RGB on my board and the RGB on the case fans are also not lighting up. I plugged the 3A (5v) into the ADD_Gen2_1 slot and tried the ADD Gen2_3 slot but nothing. I have a Montech air903 max and an ASUS z790 P-wifi. Sorry if this isn't enough info or doesn't explain the problems, but Im concerned the fans aren't working at all. At first I thought maybe they don't activate unless they need to, but since I lack experience I don't know if that's the case or I've failed to set up the power and mobo correctly. I also would just like to get the RGB set up because that's a nice added touch and I don't know what I'm doing wrong.
