My experience FWIW with box fans: we have many (dozens) in our
facility (inadequate AC) and all are Chinese. Many have gummed-up
over the years and they will sit and either start going after they
have heated the lube or just hum. I haven't had one smoke or over-
heat. Bath room exhaust fans seize and over-heat. Many of these box
fans are very low HP and can be stopped (jammed) and not over-heat.
