Here is one that the designers on Houzz suggest. You do not have to put it directly over the bed. Place it where it will catch and accentuate any natural airflow in the room.

The website hansenwholesale.com has good ratings and recommendations for ceiling fans.

This one (link below), also made by Minka Aire, is more expensive-- but we ended up buying two of these-- one in the bedroom. The cost is absolutely worth it. Not only are they really beautiful, but it is the quietest ceiling fan (3 speeds) I've ever had. After putting up with those rotating ones that make noise and get all wobbly and squeaky-- this one is super quiet and worth every penny. It's made in such a way that it actually circulates air more efficiently. I like the three bladed fans. This also has a good light-- though you don't have to install the light if you don't want it. We're thinking of getting a third one. You can adjust the length of the rod, so that it fits pretty close to the ceiling, for shorter ceilings. I'm telling you, it's worth the extra cost-- and, even though you don't want a fashion statement-- it is quite beautiful-- a work of art on its own-- plus doing a spectacular job of circulating air. And if you're gonna stick a fan on the ceiling, it may as well be as beautiful as a ceiling light would be. http://www.lampsplus.com/products/58-inch-minka-aire-artemis-mahogany-finish-ceiling-fan__70579.html

Thanks! It's nice when there is consensus ... love the second one (more expensive one) but it is too large.... will go with the first .
