They all have 4 positions: off, 1, 2, and 3.

That correlates to off, too slow to do anything, slow, and medium. There is no such thing as high from the 911 evaporator fan compared to other cars but you can buy faster spinning aftermarket fan motors that take some evaporator box modification to install from Griffiths and Retro air. Those motor upgrades only install in the top half of late 70's and early '80's evaporator boxes though.

Griffiths also sells a nice continuos fan speed switch controller that deletes the resistor pack in the passenger side return duct that removes some airflow restriction and lets you choose your own medium fan speeds.
