my temps are a little high, around 88....I have a vortex 800 fan venting air out of the room, which is 16x16x10...do I need more fan? i'm running 4000 wts of light, mostly electonic...Would I be better off using the fan to air cool the lights? If so, should it push or pull the air thru them, and can they be hooked up sequentially? Thx in advance...
