If that is true how come I can pass my hand right through the flame of a candle and not get burnt?Originally posted by fat bob
I don't see how this can be true. With any hot object sitting in front of a fan, increasing the fan speed will increase the transfer of heat from the object to the surrounding air. It's just basic thermodynamics that heat transfer increases with the temperature difference between the air and the object. When air moves more slowly across the object, the air heats up more and the heat transfer slows down. But maybe I'm missing something.Originally posted by Jim Davis
Running the blower too fast would also make the furnace less efficient because the air doesn't make enough contact with the heat exchanger to absorb any heat.

Why does an A/C freeze up if you run the fan too fast?
