Yes. It cooks faster with the fan. Btw, it's also referred to as a "convection" oven as opposed to a "conventional" oven. Air fryers are just small convection ovens.
Actually, air fryers suck in on top of the tray and it comes back from below while a convection oven just creates some turbulences in there.
The difference is that the air fryer removes all the steam that comes off the food, reducing time to crisp up significantly.
It’s blown out the slits (mine has it at the back)
Since the air is so hot and it is so little water you can’t see the steam directly but a mirror will fog when put there
