Not enough info really. Do you have a crawl space under your house? Definitely don't vent outside. The cops have thermals that can see that heat plume coming out of the house. If you have central air, that'll help. But I don't see how you're going to cool 2400W of heat with two little 6" fans. It's a good start, but you've got to find a place to evacuate the heat. Don't get a window A/C! You'll likely have light leaks, odor seeping out, and your CO2 will also be sucked out of the room along with the air. If you do SOG, you might get that many plants under a couple lights, but it's really pushing it. You probably need more like four lights. And you might consider LEDs if you can't get the heat down. I had two 1000W HPS in my basement, and replacing them with LEDs was the only way I could get the heat down. In a basement no less....
