Fan overkill? Or just right? (O.C.)

[Knyteguy]

Ok, since I just figured out my build, (i7-920) I need to figure out a way to cool it. I'm using a cooler master stacker 830 case, which has room for 9 120mm fans. Now, one thing I'm worried about is my PSU. It's only 650w, and I really don't know how far that will go with the 920, and a radeon 5870 + some fans.

Here's what I'm looking at though:
Cooler master 120mm Red LED, 90CFM 19db x4
Silverstone 120mm 114 CFM 39.5db @ max, x2
PCI-E cooling fan, exhaust
Sunbeam 4-fan controller
Fan filters x4

I'm also looking at one of these bad boys, but the sound could be completely awful so I dunno:
1st PC Corp. 252.85 CFM, 66.5db

This is pretty much the overkill one I was thinking about. I guess it'll hover over carpet n all that jazz. This also shows me there's a good opening in the market for computer sound dampening foam.

mmmm overkill??

to me personally its not enough...

those fans arent that great with exagerated specs...

Hmm, have any recommendations? Those Silverstone fans are pretty nice from what I see. I originally had 6 of those. I can't afford water cooling unfortunately, and it's still a little confusing technically at this point in time. Plus I can be clumsy and I would hate to leak some water or something like that.

open air fans? meaning they going on the case?

Or u need fans for your heat sink?

The two requirement are different.

The first one, you probably want something relatively quiet with decient CFMs.

The other u want something with high static.
Usually these arent very quiet unless u downvolt them.
