My situation: I am building my first own PC. I choose a really nice case however reviews said that it doesnt have great airflow (MetallicGear Neo Qube). I am thinking about getting an aio water cooler for my cpu (the be quiet! Pure Loop 360mm or 280mm) and want to know about the possibility of changing the fans with RGB fans. These would either be the be quiet! Light WIngs PWM High-Speed, the corsair LL Series or the Lian Li Uni Fan, I still have to decide. (I know about the dimensions having to fit, 3 * 120mm fans for the pure loop 360mm or 2 * 140mm fans for the pure loop 280mm.
My questions: Will the rgb work? Will the fans be plugged into somewhere in the aio or in the motherboard? What is the minimum air flow i should have on the fans for them to do their job at the radiator properly? And just to be sure the aio water cooling systems arrive already assembled, right? Is it even worth it? Also what kind of maintenance is there to do?
ANY ADVICE, opinions, things to consider, experience is appreciated. I am doing this for the first time and dont want to mess it up. So anything is gladly appreciated
