As several others have said, use 140mm whenever possible. You'll either get more airflow for the same noise, or less noise for the same airflow.
I notice your case also has a top fan slot. If you can, I suggest you use a rear INTAKE and put some top exhaust in there. You'll get fantastic cooling that way. And if you're using silent fans with PWM from be quiet! or Noctua, you'll barely hear the fans anyway.
Here on Youtube, someone tested temperatures with a variety of different fan configurations, some with positive pressure, some with negative, and some with neutral. He found that negative pressure - where every single fan is exhaust, and not a single fan is intake - gives the best overall temperatures, but of course, it promotes dust. Of all the positive pressure setups, the best temperatures were obtained using REAR INTAKE and top exhaust. I took some screenshots from the video and combined them into one image.
(I say "overall temperatures" because each setup has tradeoffs. For example, #1 has the best CPU temperature but almost the worst GPU and motherboard temperature. Meanwhile, #3 has the best VGA but the worst CPU. Overall, #4 is the best in terms of temperatures, while #2 is second-best. But #2 is positive pressure, so it will reduce dust.)
Of course, this assumes your CPU heatsink either blows towards the top, or towards the motherboard. If your CPU blows to the rear, then having a rear intake will just create turbulence and dead zones.
