Nathan,

As an amateur overclocker (hehehe), I think it's safe to say that it's 
not the number of fan that matters, but what kind are they and how are 
they directed.

Usually, there are a couple of rules of thumb

1. The bigger the fan, the more air it moves at the same rpm. 120 mm fan 
moves more air at the same speed than 80 mm fans. Thus, most 120 mm fan 
usually have lower speed than regular fans, and that makes the noise 
lower (both in frequency (hertz rating) and in decibel).

2. Fan positioning matters. At least have one intake and one outtake 
fans for case. A side fan can be added to cool the expansion slot areas, 
particularly Video cards (High end video cards creates as much heat as 
high end cpus nowadays).

3. Reduce the number of clutter inside your case. Buy round cables for 
your IDE cables. If not, slice them up vertically and then bundle and 
tie them.

4. If you are talking about CPU Heatsink/Fan, consider buying 
aftermarket Heatsink from Zalman. In terms of size, they are huge (I 
mean.. size of an ashtray huge), but since they use bigger fan, they 
don't create as much noise (see rule #1). I heard good things regarding 
Zalman CNPS7000 AlCu heatsink.

If you want, you can go for the "big brother" Zalman CNPS7700 AlCu
http://www.zalman.co.kr/eng/product/view.asp?idx=146&code=005

If Zalman is too pricy, you can get another aftermarket Heatsink that is 
known to be good and quiet. Look at Anandtech's Case and Cooling forum 
at http://forums.anandtech.com for suggestions. Heatsinks need not be 
pricy to be good and silent. My $10 Speeze Falcon Rock beats Thermaltake 
Volcano series in terms of cooling power, silence, and cost in cooling 
my old overclocked AXP 1700+

5. Buy a fan controller system to control the speed of your fans. It may 
be a bit expensive but it looks cool and it's useful.

6. If all else fails, consider water cooling :)

Hope these suggestions helps.
