That seems like a great idea. Currently Vents don't seem to do anything at all with this mod enabled. If they would well-mix the air on one or both sides of the vent in a small radius, that would restore their functionality and be thermatic.

Adding floor and ceiling fans would be great too.

Vents do work, but they work quite slowly. Same also applies to heat coming from Dub's Bad Hygiene radiators. So yeah fans would be very helpful

I'm really liking this idea -- especially if wall vents that had fans in them could push air from hot rooms to cool ones, etc. We could invent forced-air central heat systems! :D
