Air cooling for Carbide Air 540: keep stock or upgrade fans?

[btech]

Hello, all!

I am currently using a Corsair Carbide Air 540 because I want to stick with air cooling over liquid, I love the cable management, and I think it just looks great.

Presently, I am running a 2 way SLI setup of 4GB GTX 770 FTWs and I'm looking to move to 3-way SLI with the same cards. I purchased a Cooler Master Hyper 212 EVO as well because I plan on OCing my processor to try and keep up.

What I'm wondering is:
1.)Are the stock case fans on the Corsair Air 540 good enough? If not, what are upgrade options that will have a significant impact on the temperatures?
2.) Should I get a new 120MM fan for the Hyper 212 EVO?
2.) What ratio of input to exhaust fans should I put on the case? Aside from the stock fans, I have a single Cooler Master R4-S4S-10AK-GP fan mounted near the back to form 2 front input : 1 top and 1 rear exhaust.

Green colored LEDs might be nice if I can somehow get SHODAN etched into the side pane, but I'm fine even with colorless!

Thank you for reading my post, and I would appreciate any input.

It really depends. If you want some nice fans for your system, I recommend Bequiet's Silentwings fans. They are uber-silent and sift through air very well. For the heat sink, that's if you don't like the ordinary fans on it, I recommend Corsair's Static Pressure SP120 fans. They really work well with heat sinks and with 2 on the heat sink, makes the heat sink almost unstoppable, in cooling terms.

Depends on the noise/heat you like your computer at.

I don't mind noise at all because I wear a headset. I'm more concerned with what will keep a 3-way SLI at low to mid 80s, even lower if possible, since that's what my 2-way SLI running at now.

And, if it can't be done, then it can't be done; I'm basically just looking for the "best" 140mm fans for the performance/value that will produce a noticeable improvement over the stock fans.

I recommend Noctua NF-F12's they are silent and move a lot of air
