People say you cant use those fans for grow boxes.. But i use two standard 120mm 12v fans, one for intake and one for extraction and my grow room temps are at about 20-25c. It just how welll you have it set up, make sure you have an intake at the bottom and a extraction at the top, with a large fan (or two or three pc fans) blowing directly at the bulb above your canopy. Try to get an airflow going in one direction too, rather than several fans blowing against eachother.
If you're worried about smell however... i'd deffinitly get a standard inline fan as they have the power to suck through a carbon filter, you can pick them up on ebay quite cheaply.
Also your plant got fried purely because of how close it was to the bulb, if it was 8-10 inches lower it probably would have been ok, even with high grow room temps. The plant can withstand a few days of high heat, but with an uncovered bulb they get very very hot, especially with nothing blowing on it.
You got any seeds about to germinate soon?
