Fan death

"Fan death is a South Korean urban legend which states that an electric fan, if left running overnight in a closed room, can cause the death of those inside (by suffocation, poisoning, or hypothermia). Fans manufactured and sold in Korea are equipped with a timer switch that turns them off after a set number of minutes, which users are frequently urged to set when going to sleep with a fan on."

I've heard of this before. To be fair, we have some erroneous beliefs here in the West, such as the belief that coldness or a draft can give you the cold or flu. Both of these are caused by pathogens.

Is there any truth to this?
