This reminds me of a social studies teacher I had all the way back in like 1993. It was hot in the classroom and students would make paper fans and fan themselves. The teacher told us that the motion actually generates more heat and makes you hotter. He was right technically of course - 30 students waving something will probably heat up a windowless classroom a degree or two - but it still felt much better to have the air movement. The room I'm in now does get hot, and a fan pointing inward with one closed window doesn't help me feel more comfortable, but if I open 2 windows and have a fan pointing outward to create a current, it's great. Fans can blow hot air in an enclosed space and be unhelpful.
