Does a fan spinning at infinite speed move any air?

Impossible scenario. Cenrefugal force would also be infinite, meaning no material would be strong enough to do that.

Simple answer, yes, yes it does... even one not spinning at infinite speed/at a stand still/0rpm moves air

Now, had the question been does it blow/circulate air... thats a different story, but as for the 'move' question, all objects move air out of their way... the objects mass takes its place

Would any matter moving at infinite speed (faster than light then?) remain matter or convert to pure energy?

Would need to be a circular singularity like you might find in a black hole and the moving air would be the least of our problems?

Hypothetical infinities and rigid mechanical systems gonna get confusing real quick. Why don't you just define an upper limit for the fan speed?
Well he said infinite so I would assume it's the speed of light. So the upper limit will be
299 792 458 m / s.
