Sounds perfectly normal. The fans come when they are supposed to (223). They also run anytime the A/C is on. Not sure about the smoke. Where is it coming from?

Sound like partially condensed water vapor - fog, basically

By "air grid" I assume you mean the cabin A/C vents? I have seen what Tateos describes, but only on very rare occasions (very hot & humid). I can't think of much else if it has no smell to it.
