Jeff,

It doesn't push out much air or heat AT ALL. It pulls from bottom to top. You can see the blades go around but it is MUCH slower than a typical fan. The air that comes out is warm, not hot at all. I can't even hear the thing run at arm's length. Like the turtle slow and steady. I didn't think it would work seeing how weak it was but it seemed to work. Not sold on it yet as it is only one week in but I have high hopes on this one.
