How should I set up the air flow in my gaming PC with 3 fans?

Slightly new to PC building, had my PC for a little while now and the stock case fans were extremely loud, so I bought two Corsair AF140's and one SF120.

I made a small diagram on paint to show how I have placed them, but what sort of push/pull configuration (I don't even know if that's the right term) should I use?

The reds are the two 140's, the blue is the single 120, I have no other fan slots to add more fans, these are the only 3, I also have a GPU (AMD 6870) with the fan pointing downwards like every other card. I've been told by a friend to make fan 2 blow on to my CPU cooler (an Arctic Freezer Pro 7), and make fan 3 blow out, while fan 1 should also be an intake fan, is that a good setup? I'm hoping someone on here can give me some more guidance, cheers.

I would have fan 2 venting the rising heat out of the case, not pushing hot air from the cpu down towards the graphics card. I would also have the small fan venting and the front fan blowing in,but only if it has a filter over it. If you keep the unit 25cm off the floor it would help if there is no filter.

Oh, sorry, had no idea that would be necessary. The case is an Aerocool 6th element, and the mother board is an MSI 970A-G46.

use the front one af 140mm as intake you could had to the side panel lower part another sf 120 mm as intake then use the other af 140 mm as outake on top and the other sf 120 mm on the back also exaust this will give a great air flow and bring fresh air under the gpu .
