That would suggest, that forced air (via fan) with the aid of a shield, is more effective with heat dissipation in this application. I would love to go myth busters style on this one.
By keeping the shield in place, all of the latent heat would still be atmospherically present in it's operating environment. Obliviously the goal is to remove as much heat from fixture as possible to prolong the life of the bulbs and ballast. I just cannot see a small PC fan outputting enough CFM's to be more effective with heat removal then simply removing the shield (which I don't wouldn't suggest) and allowing the heat to escape in an open atmosphere...
Tony are you open to product testing LOL.
