Whats the dia of the one you want.

Ive practically lived in Miami my whole life. LOVE THE FISHING down there...

I also have run crab traps. In the winter we would go for pink shrimp with a light and a dip net. Now i am living in Tennessee miss that so much. I have the prototype/example to the 8 cubic foot wire trap.

I agree about using computer fans. I have used many of those fans to cool a lot of stuff and to move air around. I used to put resistors in series to bring the voltage down but it is better to use a speed controller.

I found this fan at this place where I have bought a lot of stuff before. This fan pushes 200 CFM and they consume 23 watts. That is a very large amount of air. The rating of the average 120 mm computer fan is around 80 CFM or less. You wouldn't need as many of them to do what you want to do.

As for a fan controller, here is a good one, I bought one of these and I use it to control the speed of a large fan that cools a large rectifier bank. This fan controller can control about nine of those fans.

MPJA has the same fan as the Surplus Center for $7.95 instead of $5.95.

JW, I'm looking at diameters from 8" to 14"

Magnet Juice, funny, I already bookmarked that same fan. I found an old one similar to it in my box of junk and use it wired to 6 volts to cool my inverter

Could pair this with a small 100 watt inverter https://www.walmart.com/ip/Honeywell-TurboForce-Power-3-Speed-Air-Circulator-HT-900-Black/10980207?athcpid=10980207&athpgid=athenaItemPage&athcgid=collection&athznid=829495215_collection&athieid=v0&athstid=CS020&athguid=b9015b50-c13-16d2c3817ec978&athancid=null&athena=true I use that fan to move air for when I am heating with the corn stove and to move cold air into the living room from the kitchen AC unit. Run it on low and it moves a lot of air almost silently! Yes you lose some energy in inverter losses.

These are some of the quietesr fans available.  The 9" fans are near your specs, but its pretty low CFM.  $20.00 each

If moving air is more important than quietness, this is 1250CFM for the 10". $33/pair
