Which 80mm case fans?
 

Hi people,

I am planning on buying me some (2) case fans as a replacement for my old and noisy (80mm) antec casefans. The case I'm going to use is an Antec SX830. Now the parts I'll put in my case:

- Athlon64 3000+ S939
- Asus A8N-SLI Deluxe
- Corsair TWINX1024-3200C2
- Leadtek GeForce 6600GT
- 120 GB Seagate Barracuda 7200.7 SATA with NCQ
- Plextor 504A
- Floppy drive
- OCZ PowerStream 520 Watt

Now the question is which fans do I need? How "powerful" do they have to be to cool my system? I want silent ones. But I can't make up my mind on which papst fans to get. Another problem I am facing is that the fan holders of my antec case are 80x80x80x32mm and all these "nice and silent" papst fans are 80x80x25mm. They'll probably fit but I don't know if they'll be stable.

Can someone help me out here? ;-)
