Possibly a faulty rad fan sensor or relay / wiring or it has been wired up that way for whatever reason .This shows you the set up , should help you .

If rad fan is running all the time the engine will struggle to reach operating temp and could affect mpg.Apart from the power it's using it will eventually wear out due to over use .
