I plan to use 6 fans. 2 in the top, 2 in the front and 2 in the rear. Most likely 140mm's in the top and the other 4 will be 120mm's. I wanted to know in what direction should the air flow for the ideally lowest temperatures? I'm aware that hot air needs to flow out of the case while cool air flows in but what is the best way to go about that? Also, is there a better fan set up than the one I plan to use? I'm open to all suggestions. All of the fans are by Corsair and I did order a fan controller as well. Much appreciated - Alex

Your parts are not unusually hot; I think you could go with the supplied stock fans.
A 200mm front intake fan that has a filter will keep dust out of your pc and provide plenty of cooling air.
Whatever comes in will exit someplace.
If you have escess exhaust capability, they will draw in unfiltered air from many openings destroying the positive pressure airflow.
The case comes with a fan controller.
I suggest you try out the stock fans first and see if you really need more.
It is easy to add fans later. No need to add expense and noise prematurely.

Yeah that is a fine setup. Air should flow in from the front of the case (and the bottom if you were to put a fan down there, which you dont need). The air will be heated by the components and should be pushed out the back and the top of the case.

Ah, thank you for noting that. I hadn't noticed the included controller because the case was suggested to me by someone else. I'll set the extra to the side for when I eventually change the case. I wasn't sure if I'd need the extra fans but I was told that stock fans aren't good for any build and that I should upgrade them right out of the gate. I'll use the stock fans first. It saves me a bit of unscrewing anyway.

Also thank you guys. I'm glad I asked before screwing that up. Front fans bring air in, rear fans push air out, and top fans also push air out. Do you recommend a specific brand for the 200mm filtered fan by any chance? If not I can look around and read some reviews.
