How many fans should I have for an OC'ed case?

[BillStuck]

sorry I'm an OC'ing n00b. I am trying to decide between 4 80mm fans or 2 120's. I want it to be as quiet as possible but keep it cool enough. There are so many fan choices with different CFM ratings. I have no idea how much air movement is enough and don't want to have to buy better fans later.

Any advice you can give? 4 80mm fans vs 2120mm fans and what CFM rating they should have? I hear panaflo are good but i dunno

I'm going crazy for the past week shopping for a new case, and from what I've read, 120mm is the way to go. I believe as one person put it, 2x120mm undervolted is the better than 4x80mm. My first choice would be the Chenbro Genie/Genie Junior. It has 120mm exhaust, 120mm intake, and 80mm hd fan. It's not available in many places, and it's somewhat expensive for me (over $100). Then there's the Antec SLK2700AMB, which has 120mm exhaust, 120mm intake, and that should be fine anyway. There's my 2 cents.

thats the Antec i'm looking at too. I plan to overclock an XP2100+ if that matters.

Also the fan choice is another thing. There are tons of 120mm fans with different CFM vs noise and I have no idea how much CFM air movement is enough.

I have 4 panaflo's in my case and it is pretty quite except for my psu fans. I am debating whether or not to switch those out with L1a's. My case temps stay below 28c.

thanks cat. Where can i see these L1A's newegg and mwave don't seem to have much selection. Maybe they have a 120mm version. I like your temps.
