I want to install a Nepton 240M in my XAF XB EVO. I thought I would have to remove the fans I have now and use only the ones on the radiator. Now this push-pull setup is interesting but I am not sure I understand it. Does it mean the case fans on the front pull fresh air inside the case while the radiator fans push hot air outside ? It seems to me that the fans would just be "fighting" each other, restricting the flow and keeping the hot air in this area where the radiator is. And I am also wondering about noise. I think 2 pairs of 120mm fans blowing against each other must be generating noise. So what would be the best setup ? Push-Pull or just 1 set of fans ?
