That one's interesting in part because South Korea mostly doesn't get that hot. (Summer highs seem to be mid-80s Fahrenheit.) Looking at climate data for the country, I was struck by how similar it is to upper Missouri. Saint Louis is about as humid, but a bit hotter on average. Which would make me suspect that if "fan death" was a thing, we'd be seeing it in a band of US States that're similarly hot and humid. Speculative difference would be if air conditioning is really uncommon in South Korea, but presumably we could even that out by comparing to poorer people in the US.
