From the current issue of Home Power magazine:
"Making the Most of Your Ceiling Fan"
http://www.homepower.com/articles/home-efficiency/electricity/making-most-your-ceiling-fan
The temperature of the motor was far higher than anything
else in the room, including windows exposed to direct sunlight.
Not only was the fan not cooling the people who weren’t in
the room, but it was also working as a little space heater.

Is this a joke article? He lists some useful info and then draws faulty
conclusions. I think the lead in line is a perfect example...

A ceiling fan can heat up to about 100°F when running

Wow! 100°F!!! That is pretty much nothing. The incandescent light
bulb in the same fixture is thousands of degrees and likely puts off
more heat. I think the case for the fan heating the room is a bit
overstated. More useful would have been a simple statement of the
wattage of the fan. The comparison to the windows is totally absurd.
They let in direct radiant heat from the outside. I can assure you than
nearly any window in your house lets in more heat in the summer than the
fan puts off. The temperature of the glass has no bearing on the heat
coming in through the window.
