I would like to get positive pressure and from what I can see in my case ( Define R5 ) I can't mount a 280mm rad Corsair 115i AIO on the top, the only place it will fit is on the front, no biggie. After reading and watching videos on if it being on the front matters or not and I'm settled with it. Anyway, I want to know if I can put 2x 140mm SP fans on the outer most part of the case pulling, with that can I put 2x 140mm AF fans on the other side of the rad pull air through the rad with the other two SP fans pulling air into the system? Or do I need to get 2 more SP fans to put on the side of the rad. Mainly wondering if it would make a difference if I used either AF or SP fans for the 2nd set of fans on the other side of the rad. This all being the done with a 140mm AF fan is in the back of the case pulling air out.
