When cooling down a hot room, is it better to point a fan out to get rid of the hot air, or point the fan in to input cold air?

If there's only one channel for the air to flow, they would both accomplish the same thing. You're not creating a vacuum when you turn a fan outside; an equivalent amount of air is coming into the room.

If the fan is low to the ground, in and pointing up
Better to aim it along a wall to get air circulating. It'll create a current that moves air in and out of the room.

fan blowing out
if the fan motor produces any heat it won't have to move through the room to exit
Otherwise there isn't much difference other than convenience

Two windows and both or get central air, poorfag.
Fans don't input or output temperatures.
They move air around.
This has a cooling effect, but cool air isn't "sucked" into it and spat out, and "warmer air" isn't suck into and blown out.

Point the fan in so that it pushes the air with moisture out.

Outgoing hot air fan, because it decreases the temperature and pressure simultaneously, so the effect is consistent on both sides of the ideal gas equation pv=nrt.
The cold air input increases the pressure, so the temperature might stay the same, depending on the temperature gradient and windspeed of the fan.

OP here. I am using a fan to move the cold outside air in or move the hot inside air out. I'm aware fans don't generate hot or cold air.
Assuming the fan is place next to an open window with cool air outside, blowing inward would be most effective. If you blow outward you're just moving warm air elsewhere in the house into your room whereas blowing inward brings in cool air.
blow it out your ass

>Not creating a vacuum to get optimal coldness
vent top outward with fan, lower passive
fan pointed at you best feeling while overheating, then you get cold and it's annoying
can't win

if you have only 1 opening (window or door) you're not going to move much air into or out of the room.
