I would center it (not above the bed).

If ceiling fans were for looks, I doubt many people would have them. The remodelers centered mine over the foot of the bed and I wish they'd centered it over the center of the bed. In summer I need all the air movement I can get from that fan pointed directly at me and not at my feet.

i would center it over your bed (photo 1). your bed placement is reasonable, anyone would put it there. might as well get full value of the fan.

i can recommend the minka aire pancake, we have one and it's great.

What did you decide and how is it working for you?
