My first proper cable managment... kind of. Also there are 3 intake fans on front+bottom and a single exhaust at the back. Makes sense? AllTheCases.com/Fractal-Design-Define-R3
I have the same case and fan setup. More in than out is better, because that produces a positive pressure, making air escape from every hole. If you have more air out than in, the opposite happens, and dust gets in more easily.
