I don't see a problem, but perhaps someone else will. But things really depend on the fans and size of the setup. You want air to linger a little in the container, but you want fresh air to be abundant as well and it works by simple math. Fans are measured, among other things, in Cfm (cubic feet per minute). Now in order to measure the cubic feet of your container, multiply the length, by the width, by the height and that will give you how many cubic feet you're dealing with. Then just find out how many Cfm your fans are pumping out. Also, do you have a thermostat checking the temp. of the intake air? Once you know these things people can really help you out.
