Need help with configuration

[dididan2000]

I have a Corsair SPEC-02 case. It has room for two fans in the front, two on top, and one rear fan. The two in the front are fine. It's the top ones and rear one I need help with. I got a Corsair H75 CPU cooler. It comes with two fans. Each is installed on both sides of the cooler. Now I have it installed like that but since I do, I can't fit two fans on top and could only fit one. What I'm asking is this: Should I have two fans on top with one fan for the cooler in the rear, or have one fan on top with two fans for the cooler in the rear which I have right now? The reason I'm asking is that I'm worried that dust will start to sit on top of my power supply if I don't have a fan on top there to "block" the dust. Yet again I'm overclocking my CPU so two fans for the cooler would provide for lower temps. I don't know help please. Thanks!

One fan in the top is fine. For the dust it's going to get in anyhow even if you added another top fan.

What do you think of the air flow? Like would it be better to have the other set up with the duel fans on top? I have my front and top fans as intake, and my rear fans with the cooler as exhaust.

Don[t use the top as intake.
Front bottom side Intake, top back exhaust, that is almost always the way to set up case fans.

So I have my two front fans as intake, my bottom as intake, my top as intake, and my rear as exhaust. Why should the top fan be exhaust?
