So they will definitely consume less power than a fan for removing a unit of heat from a home. Same with a heat pump vs electric heater. The heat pump uses less energy.
Fans do not remove heat. Fans actually add heat into a home. Unless if the fan is placed by an open window and it pulls in cooler air inside.

Which is how many people use a fan, when it's hot out I open the windows in the evening and use 2 window fans to pull in the cool air, then close up the house in the morning to keep it cool. I haven't done the math on the COP, but I'm pretty sure it's much better than running the AC. A fan in a room may not remove heat from the room but it can make it much more comfortable at a higher temperature, reducing the need to run AC.
