Looking for a cooling fan source

[Hack]

I am currently trying to rework my controller box to hold my xylotex board and power supply and I am looking for a fan to cool the thing. I don't want to mess with a bunch of PC sized fans and would like to only install one with adequate CFM.

Any Recomendations as to what the proper size (CFM) is? Any good sources? What can i do to help control dust entering it? Filter material of some sort? Will this decrease the CFM?

I prefer a 24 volt fan so I can just hook it up to the power supply. Controller box size is about 11 1/2" x 11 1/2" x 3" if that helps. It also has a few holes in it to help with airflow, but otherwise is fully enclosed.

Thanks all.

Well anything above 34 CFM is probably not useful unless you provide more exits for the air....you could get a fan that will work with a higher static pressure...well it's actually more of a blower. Mouser.com and they are about $13 new.

Here is a site with a lot of technical information and a large selection of fans, which might be of interest.
