Think gentle air circulation. Not cooling. The fans don't "cool" anything. Just aids the natural convection currents that happen in a refrigerator without any fan. There's probably no right or wrong flow direction.
Camco sells battery operated toy like fans for pennies. These run on batteries for ~10 days at a time. Anything more uses unnecessary power draw and to some extent, heat (from fan motors).
