You need to vent at the top and bottom... At the botton you can put in a 8" fan, at the top you can use Dundas insulated 4" conduit and an inline fan to move air from the top of your room over to an exhaust outside. It looks like you're in a garage, so there should be some venting around going outside. Here's a couple of links:

Good luck with your room man...
The S3's are all venting out of the enclosure. The only problem is they cannot pull enough air into the room. A simple whole in the wall will suffice to fix the problem.
Also, to the OP, your insulation will still be very beneficial to keep the radiating heat from coming through the walls. It just would have taken some extra math to learn that 16 S3's have more CFM than your window AC can move. Who knows....Maybe just removing the window barriers next to the AC would be best.
I agree with this. get an AC that will push more air than your S3's combined
The overall misunderstanding is in how an AC system works. The AC unit is not pulling the hot air from inside the room to the outside. What it is doing is a fan is pulling ambient temp air from inside your room, and moving that air across a coil that is cooler than the ambient air. The colder coil absorbes some of the heat energy and removes some of the moisture via the beer can affect. The ambient temp room air that has gone through the coil gives up some of it's heat into the coil, and left some of it's moisture condensed on the coil and is returned to the room drier and 8-15 degrees cooler than it started. That particular AC is a closed system and doesn't move any air from inside the room to the outdoors, or from the outdoors to the inside of the room. The hot air you feel coming out of the AC on the outside is the "heat energy" collected from the inside air through the cooling coil. On the outside, another fan blows the outside ambient temp air across the now hot coil, pulling some of the heat from the coil then recirculates the reduced temp coolant back to the inside to soak up more heat energy from the ambient inside air. I found a good video that illustrates how it works on youtube. http://www.youtube.com/watch?v=6OU7WHgJ_cY
Air from inside the room is blown across the cooling coil, then back into the room, this keeps the pressure of the room static or unchanged.
Now with the miners doing what they do, how you currently have them configured, is attempting to pull cooler air from inside the room through the heat sinks, picking up heat energy, and exhausting that warmer air outside the sealed room. With no air being let into the room (not through the AC as previously assumed) and all of those miners trying to pull air out of the room...creates a vacuum or negative pressure zone, that's why the door slams shut since it opens to the outside of the room which is now a positive pressure area relative to the lower pressure inside the room. If that door was hinged on the other side of the jam and swung into the room, the miners would be sucking the door open when pulling air into the room. Your concept is pretty good, however, you should try sealing the miners inside the room entirely. Seal off all the exhaust holes, and mount the miners vertically so they are sucking cooler air up from the floor since colder air sinks, and exhausts out the top as hot hair naturally wants to rise away from cooler air. Then your room will be back to a static pressure area, where the cooler air coming out of the AC unit sinks to the floor, gets pulled up through the miners heat sinks and the warmer air naturally wants to rise out of the miners. In this fashion, your using the miners fans to help the already natural convection current, of cooler air down, and warmer air up. I have my miners running in a small room, the ambient temp of the room about waist/chest high is 78-80F. I have my miners mounted vertically, pulling in the air from down by the floor ~74F, (2-3 degrees cooler than midzone), when it comes out of the miners, its much warmer ~94F(warmer than midzone) and rises to the ceiling where it's apx. ~82F. If you mount 3 digital thermometers in your room, you see the thermocline, or temp difference between the floor, mid, and ceiling height. Give it a shot...your miners will never run cooler unless you put em in a freezer.
Yes my current have same temperature, from some pictures I have seen of heatsinks removed I noticed very bad application of the paste. I don't expect too much from the assembly line.
