Today, I just built my first ever PC. And I'm having problems with the case fans that the case originally came with installed. My case is a Montech AIR 903 Max. It comes with ARGB fans. I turned it on and every other fan or cooling system in the PC works except for the case fans. RGB doesn't work on them either. They don't light up and they don't turn on to spin. The manual doesn't explain further on any of the cables and connectors for these fans and I don't know what to do. To anyone else with the same case, is there something I missed when I did cable management/PSU work?
