Running mid-range gaming builds with 1 fan? Exhausting out front?

[SingingThroughTheStorm]

So I finally jumped on picking up a Fractal Core 1000 and paid $37 for it.
It will probably be holding an i3-2100 and a 6850, but in the future chances are it will have an i5 + 7850.

I would like to know what would be the best use of cooling for the PC in terms of being minimal in sound.
It comes with a 120mm fan, which only operates as an intake by their setup. Would that be sufficient alone?
The thought of flipping the included fan to exhaust through the front crossed my mind.

Would running a single fan as intake suffice for a build that consists of generally low power parts,
or would the fan running as a front exhaust be preferred? Or would adding an additional fan be better?

If you have more fans you can move the same amount of air with them running slower and making less noise. Also, a front exhaust is generally a bad idea.

How about running just a single front intake giving the case positive air pressure?
I could also run a second 120mm as exhaust on the side panel, then having the front intake and side exhaust.
I would go with a more common front pull and rear push fan setup, but the 92mm fan size is an odd one, and I don't want to pick up another fan. :lol:

Well, with power-efficient components and no overclocking, it should work alright with one case fan.
