Those fans arn't really made to do that job, though depending on your container size, a few of them WILL get it done nicely. Just 1 is testing it IMO. What you really want is a centrifugal fan; 300+CFM, and made to overcome static pressure; loud and overkill mostly. The most well respect brand for quietness is Can-Fan.

But only 8GPUs you should be fine without that. Keep your gpu box as small as you can, another duct booster and you should be fine.

The fans I linked are 500 CFM per fan...

I realize that. But the cost is effecting the profits.
This fan (70W 334CFM) for $146 http://www.amazon.com/Can-Fan-Inline-6-Inch-Minute/dp/B004C2IWIE
This fan (138W 392CFM) for $124.99 http://www.thehydrosource.com/can-fan-inline-fans.html

Really though at that point might as well look at http://www.iaqsource.com/product.php?p=panasonic_fv-40nlf1&product=111092&utm_source=amazon-pads&utm_medium=cpc for $200.

Anyways I'm going to try and get by with these $30 6" duct fans. If that won't pull enough hot air out then I'll look to bigger setups but will consider price. I'll know by the end of this week.
