These tend to be pretty loud, but they do seem to have what it takes to move air. I think they can be gotten at Home Depot; as long as you don't mess it up, it can always go back. If it's an easier fit or a better solutuion--go for it. But please be sure to report back!
Though I would be remiss if I didn't remind you that the Vantec Tornado moves the same amount of air, in a smaller package, is quieter, and cheaper--you can get two of them for $25: http://www.ultimatepccooling.com/vato80fan.html

I borrowed this really sweet adustable power supply last week and was toying with all kinds of fan speeds and timed on/off cycles. For me, any time the fan wasn't on, I'd get stratification and dead air spaces. The coffin itself is a cold sink, even with a good layer of insulation--it's the weakest link in our design.
If the fan is cycling on and off then the in-coffin temps are varying, then the compressor needs to work that much harder on the next cycle.
With the fan on full time, the compressor goes through more
cycles but they are shorter
in duration. Then there's always the cost of another Love controller
One of those and I am halfway to a new fermentation cab
The noise is there, and I work all day about 10 feet from it...it's tolerable.
