I haven't used a fan to cool myself off (I don't do this for a living), but as a birthday gift my family bought me this fan back in Feb.
Here's a pic:
It moves a lot of air, you can easily adjust where you want it to blow with its pivot design, and it has 2 accessory outlets if you want to run other devices.
You can pick it up at any Sam's Club for $50 or $60? It's come in handy many times around the house and it helps speed the interior dry time. In fact, I have it running upstairs right now because my father-in-law had an accident and whoever built this house years ago thought it was a smart idea to install carpet in the bathroom.
