The Cooler Master Silencio FP120 PWM seems to be a great option.

44 CFM airflow, 14dBA noise level and a $10 price tag.
Just ordered a pair and will see how they perform once I get them ^_^
wow, that pair seems nice, but couldn't find them in my country!
Another thing I didn't comment: My case is a Cooler Master Silencio 352, with sound dampening panels.
Would it be better to use a pair of fans focused on static pressure or airflow?
I agree with anotherdrew.
This excellent explanation by Linus might help you understand more, and decide for yourself ^_^
For a sound dampened case I would personally prefer an SP fan over an AF. But choosing a fan that is well rounded off between SP and AF is never a bad idea. As per the general opinion, it is said that SP fans usually perform well as replacements to AF fans (but NOT the other way around).
Best of luck to you!
