How much cfu is really needed?

[knives]

hi,
i was wondering how much airflow is really needed? i am looking for a quiet setup for my computer, and planning on 4 case fans (2 in and 2 out, 80mm, cheiftec dragon case).
most quiet fans have low cfu usage.

how should i look for a good fan setup? how many total cfus should my case contain? i would like to keep it as cold as i can.

any hints?

First-off, its CFM (Cubic-Feet per Minute) of air... And if you're looking for a quiet solution, you can always go for some quiet Panaflo or Papst fans (try <A HREF="http://www.highspeedpc.com" target="_new">http://www.highspeedpc.com</A>). the best you'll get is about 35cfm to ~27db, and if you've got 2xfront and 2xrear you're fine as for airflow. If you want to go a little higher, check out some of the Sunons available (all over, just use a search-engine). They offer some ~40cfm solutions at about 33db. Add a fan controller (like Vantec's Nexus) and you can either control it all manually with knobs, or have it all temperature regulated (the fan speed btw).

Ahhh! It's 2003 and wait, whats this!? My computer didn't blow up! ... Well damn, there goes my new Athlon @ 333FSB and my inssurance claim... heheheh
