Well there, yourself. I already stated :
"The electric motor on the fan will generate a small amount of added heat for the room air."
Heat/thermal energy transfer that would not exist if the fan were turned off.
Of course, the incremental amounts of heat and energy we are discussing are trivially insignificant - which is what old farts do!
