First time pc builder here, recently bought a B450M Steel Legend motherboard and a NZXT H500 ATX Midtower case (both by recommendation). The first chassis fan port works just fine but the other two at the bottom of the motherboard dont seem to power the other fan. I have the cpu fan and the top fan hooked up and running, the one to the side is also hooked up but just isnt working. The fans and cables work just fine so to my knowledge it must be the ports. Id rather my first build not have a 2 out of 3 functionality rate so anything to help would be very appreciated!
