Help Me find a good fan layout

I have a CM Storm Scout 2 Advanced case and was wondering what would be a nice layout of fans for air flow and cooling, i plan to buy 5 Corsair AF120 Blue LED fans.

The layout i had in mind was putting 2 fans on the side under the window to pull cool air into the system then i would have two fans in the front of the case to push the hot air out of the front because my PC would be on my desk so i can see inside the window and i didn't want hot air shooting out the side right at me. Would this be a good fan layout for cooling, i would also put a fan on the back and didn't know if that should be push or pull?

I don't know if this matters but i also planned on mounting a H100i on the top of the case, it kind of sticks out halfway on this case and i like how it looks, plus it would allow me to overclock my CPU to around 4.3ghz.

Update: Would it be good if i did the 2 fans on the side pulling air into my case, the 2 fans on the front pulling air into the case and 1 fan in the back pushing the hot air out?

I cant do any air coming out of the top because i plan on mounting a H100i in the top of the case with its fans on pull for easy cleaning.

best thing i found was running like prime for 10 mins, checking temps, moving my fans around, running again for the same amount of time, checking temps and see what worked best in my case and not what someone who doesn't have my pc says would work better. oddly enough, what works best for me is my rad's blowing in, front fans blowing in, bottom fan blowing in and just my back fan, psu and gpu blowing out. Might not work for you but that's what testing did for me.

Basic cooling concept:

Cool air in the front, hot air out the back, and optionally top.
If you need more, side fan blowing in.

Who doesn't love huskies?

On topic, the CM Storm Scout comes with 3 fans already yeah? And you want to add 5 more? That is an awful lot of fans, and probably more hassle than its worth (lots of wires and you'll probably need a pretty high spec fan controller to run it)

As for layout, I'd stick to conventional wisdom - Front+sides+bottom=intake, Rear+top = Exhaust.
The main reason for this is that most of your very hot components (CPU+graphics card) are right next to the back of the case.

A lot of those fans aren't going to be doing an awful lot. In all the testing I've seen, they show diminishing returns from every fan added after you have an intake and exhaust set up. The main exception to this is if you run a multiple graphics card setup and can install fans above the graphics cards to supply them with cool air.

+1 for the air in front/side, out back/top wisdom (But always cool air in over the water rad)
5 fans is going to sound more like a hovercraft than a gaming rig. Three fans will be plenty.

No i was just going to replace them with 5 of the Corsair AF120 Blue LED quiet editions so that it would be quieter and look nicer.

They are the quiet edition fans so they wont be noisy.

The only issue i have with that is that i will be running a H100i with the radiator mounted halfway out of the top of the case, i plan on mounting those fans in pull that way i can clean it without having to remove them.

Quiet does not mean silent. Usually, the more fans = more noise. In some cases, more = better airflow so they can run slower. But you'll have to test it specifically to see.

I usually subscribe to "less is more". Only add fans if absolutely necessary.

Ok i guess i will have to wait till Christmas so i can get my Fans and H100i, i will try out of couple of the solutions that people gave me and some of my own ideas and see which runs the best. On a side note what is a good test to run in prime95 to test my airflow and cooling over 10 minutes?

I have heard them on full speed and they are really silent. Adding 2 more wont affect their noise because they are so quiet.
