Airflow - Need Help!

[Windows10Home]

I'm building my system soon, and wondered where to put the fans. I'm getting a Define S, and a 280mm watercooler. I am also getting a Corsair AF140 quiet. I was thinking of putting the AF140 in the front, (Don't like ModuVent) but I wondered if I should put it at the top or the bottom of the front. I am going to put the radiator in front also, so... should I put the fan on top or bottom?

(The other specs are in my signature)

Exhaust blowing out the top. Intake anywhere else if you want.

Isn't one fan at the back enough?

Not if you really want to keep your system cool.

What's the best positions then?

You can do that, but it'll end up as 3 intake vs 1 exhaust.

 

I would have 2 intake in the bottom, 2 exhaust on top.

So the air stream would grab the GPU's exhaust and radiator's exhaust and toss it out the top.

The warm air will rise up and not come back into the system.

There is only 1 intake at the bottom

Ah then one of them can be put on the side or rear.

There is 1 in the back, 1 bottom, 3 top and 3 in front (fan positions
