Tent fan that's out of the way.
The Cool Zephyr Window Fan is my choice for best tent fan. I have used the Cool Zephyr Ceiling Fan With Light (reviewed separately), and that's a decent fan. Now let me tell you why this one's better. 1. The window fan doesn't take up head-room. This is relevant for head-bonkin' reasons, and for gear storage. If you are planning to use a gear-loft/tent-attic the ceiling fan may get in the way. 2. It mounts on the window mesh of the tent, this keeps it out of the way, and it brings in fresh air. The ceiling fan may bring in fresh air, but I wouldn't count on it unless it's right under open mesh. 3. It's aim-able. You can pick which window to mount it in, and where in the window to mount it. This gives you some control over where it's blowing- like on you or not. 4. It can stand alone. It has a built in stand that can be use to place the fan elsewhere, like on a picnic table. 5. Air volume. This is purely subjective, but I think the window fan moves more air. There a couple things that are better about the ceiling fan. The ceiling fan uses 4D batteries that last 24-48 hours, while the window fan uses 6D batteries that last 20-40 hours. I've never run the batteries out, those are quoted figures, but they seem reasonable considering #5 above. The ceiling fan also has a light. An overhead light is a very nice thing to have in a tent, but I think the fan factors outweigh it.I recommend getting the window fan, and find another source for light, or get both.
