For $10 you can get a magnetic mount from Amazon that clips to any vent. I've considered getting one for the summer months, where the direct sun on my dash top mount causes my phone to get uncomfortably hot. Putting it directly in the a/c air stream would work well, I bet, though it might block the air from reaching a hot occupant somewhat. I didn't do it yet because the vent placement in gen1 means I wouldn't be able to see the screen very wheel due to it being blocked by the steering wheel in that location. But if your concern is more cooling than screen visibility, it would be a decent solution.
