Car is overheating while on idle

What is your question?

I have a 2011 Honda Accord EX-L V6. My car has been overheating, it overheats when on idle when the A/C is on. When I drive normally it doesn’t overheat because the gush of wind flowing through the radiator is what’s keeping it cool. Only when I idle for a few minutes or stay put for a few minutes while stuck in traffic. I understand that the A/C puts on more load onto the engine, but I don’t get why it over heats. First mechanic thought it was the Fans so I’ve replaced both, but issue still seems to persist. Second mechanic thought it was just my condenser & radiator fins were dirty and clogged so we cleaned it, but problem still exists…. What can be the issue? I’ve inspected my car when it starts overheating the radiator cooling fan doesn’t engage when overheating while engine is overheating. The fans work since both of them turned on a few mins of cold starting my car in the morning. I’m not sure what else could be causing my car to overheat.

What makes this problem better or worse?

When A/C is on
