well... sorry to say, ive never had that "burning" effect that i see in your pictures. But i WILL say that in my experience, too much wind = bad.
My plant has a desk fan blowing on it from the top (about as big as yours) and the all the leaves in the path of the wind are curling down the sides.
Once i changed the position of the fan and turned it down, the leaves slowly started to open up again.
