I ran it in the stryofoam a few times . Because the fan was so strong and Jessshan told me not to run it without the fan. I just couldnt control humidity in there. It would blow the whole pan dry in a day.
those fans do wipe out the pans granny, but they are like that so they send the heat around, most people set up a 5gal type system above that feeds that pan so they dont have to keep filling it all the time.
