Nothing

I have disabled the fan.

None. It is unlikely to happen but made more likely by those who prepare for it and then mouth-off about it.

It is the scheiße-stirrers who are the real problem.

When the shite hits the fan, I open my umbrella.

I'm gonna write a letter to the international space station to ask if I can join them and slowly starve to death.

None whatsoever. Seems like something crazies enjoy fantasizing about.
