The fan is just to push the cold air out - the amount of airflow doesn't give much cooling effect.

Yes, with >10x the power consumption, you can have somewhat better cooling than a fan.

>you *die within hours at best*.
There is now clothes available that insulate well enough that you won't die no matter how cold it is, even right in a blizzard, but those are inconvenient.

In a properly insulated building, you won't die within hours with decently warm clothes.
