I get huge value out of running a fan at night. It helps me to be able to adjust temperature much more quickly when putting a foot or leg out of the covers, and as a bonus, the white noise can be nice.
I linked my favorite desk fan, the "Vornado Zippi Small Personal Fan" — I love the small size, the fabric blades, and the interesting mounting options (e.g. hanging upside down off the edge of a shelf).
But a standing fan is maybe more convenient at the end of the bed. e.g. Seville Classics UltraSlimline 40 in. Oscillating with Steel Intake Grill Tower Fan
