Smoke coming out of the intakes.

You turned the A/C on to get the coolant temp down? Wouldn't that have the reverse effect? When you say 1 o'clock you mean inching towards 250? I've never had mine go much past the '8' (just left of noon on the clock dial) even while sitting on a hot/humid day in traffic for an hour with the A/C going. The secondary(?) fans turn on by themselves regardless if my A/C is on.

Wow. Seriously? Mine always danced around the 0. Even with three big ass radiators now, I still dance around 0 (but I also have a bigger engine now).

I also live in Arizona where temperatures are excess of 110, but yea.

I think he turned his AC on to get his fans running, but if the ECU worked, the fans should turn on automatically.

when I'm in stop in go traffic, a lot of that idling in neutral, which is terrible for the engine, I rarely hear those fans go on by themselves right away. My thinking was that the AC speeds it up.
