I actually read it a really long time ago, but I just read it again. Let's review how my scenario is like that which allegedly causes fan death:
* I do not open any windows. Ever.
* My fan does not oscillate (it is a ceiling fan).
* I sleep directly under it.
* I have it on all the time.
* We face extreme heat. This is Arizona. It's well over 100 F all summer long, often closer to 110 F. That means 40+ C most of the time, for you metric users.
* The humidity is usually low, so if it kills you via evaporating all your sweat, these conditions should dry you out faster than anything else.
I have done this all summer every summer for some 15 years now. I am still alive. Heat stroke can kill you. "Fan death" will not.
