Nice. It makes sense.
In either case, with a horizontal orientation, all the force is being exerted onto one small point so seems it would have to be a pretty cheap fan for the up or down orientation to make a significant difference in the life of the fan.
Exactly. I have a $2 fan that works as well as any other sleeve bearing fan. The difference was the markup.
