I would say that it depends on the temperature of your tank... The cooling fan "throws" the hot air from your pendant/canopy and into the room so that your tank does not get overheated... If you don't have a problem maintaining a lower temperature in your tank, then you don't need to have your cooling fan on... Hope this helps...
