Light movers w/ air cooled hoods HEAT PROBLEM

i am about to set up 2x600 watt lights on a single light mover with a multiple lamp kit thing. they are air cooled hoods, so i was wondering what the easiest way to set up a fan to exhaust the hot air from them would be. should i get a tandem carrier to travel with the mover, or have a stationary fan on the wall, or even attach an inline fan to one end of each hood? Is there any way to put up a small PC axial fan or inline duct booster fan in/on the vent holes of the hood? any response would be appreciated. thanks.
