I can't imagine -any- hushbox would not need ventilation running whenever the projector is running (they put out a LOT of heat). Thus it makes more sense to turn the fan on whenever the projector is on, no?
Maybe you're trying to kick in some higher output backup fans if it gets too hot? In that case, I'm sure hooking a thermometer to a relay could be easily done, but I'm not into that sort of stuff so I couldn't give you any part numbers, sorry.
