Antec CS600...two fans or four?

[Redshirt #24]

I've had this damn case sitting behind the loveseat in my living room for three months now, and I finally picked up a pair of 80mm Vantec Stealth fans to shove in there (I'd prefer a local cheap source for some really well-regarded fans like Yate Loons, but hey) so I can finally move the system out of its godawful SuperMicro server case. The question is probably slightly stupid, but hey: since I'm not doing anything really extreme with my rig, should I be generally okay with two case fans--one intake, one exhaust--or should I take these back and get some cheap sleeve-bearing fans to max the thing out?

One in back and one in front is all I have ever needed. Depends on how much air the fans move. If they are low rpm then you may want to use all four. Try just two and if the temps are good then that's all you need.
