Hello, I am purchasing a Corsair 400r and I was wondering, what is the best fan layout for this bad boy. Should I replace the stock fans with aftermarket ones? Also, should I use the top 2 fans for exhaust, or intake?. I am thinking as of now, use the back, 2 tops for exhaust, and the 2 front, 2 sides, and 1 bottom (if i have space with my psu) as intake. Also, I am purchasing a Intel Core i5 3570K, 16GB Corsair Vengeance 1600MHz RAM, a WD Caviar Black 1TB, 1 Corsair Force GT 240GB SSD, a Optical drive, and a Galaxy GTX 670 GC (OC'ed). My friends say that 850W has enough head room for OCing, and possibly SLI in the future. But for now, is 750W, or even 650W enough? For SLI in the future, would I need a 850W. Also, I might OC the RAM, CPU, and possibly GPU in the future so it keeps up with demanding games.

Thanks for the help.

i found the corsair fans on my 400r too loud and replaced them. make the front fans intake, top and back exhaust. play around with side fans as they can often increase temps. frankly i just closed off my side panel to hold in noise.

a quality 550w+ PSU is enough for a single GTX 670, for SLI look for a quality 750w+ PSU.

Thanks you for the reply, I see what you mean about the side fans increasing temps, did you replace the front fans also? I might put the HDD fans if I have enough GPU headroom. What fans should I purchase? 140MM or 120MM?

Will those be loud in you opinion?

I might put the extra money toward a cougar or a corsair, they are supposed to be very quiet. On your 400R, did you put 140MM or 120MM fans?
