Aron,
The template shouldn't be the cause, unless it has it's own caching system built in. Can you let me know if the Fan box shows properly when a user is logged into the front-end?
In general though, if disabling the System - Cache plugin fixes the problem, it definitely narrows it down to a caching issue.. we just need to figure out what caching extension, template, or feature is improperly caching.
Thanks,
Alex
