The heat is a function of the ballasts, not the bulbs -- also the light
table construction. If you use digital ballasts, no heat, or none to speak
of, and if your "box" is open on 2 sides, heat should not/may not (mine is
not) be a problem... In my experience a fan is just more noise, wind &
clutter.
