I've had no trouble with Sturmey Archer 3 speeds at any temps.
I've commuted on my SRAM Spectro 7 speed and SRAM Torpedo 3 speed at -10° F. without problem in the past three winters. Over 25 years ago I commuted in temperatures as cold as -15° F. on a S-A S5 hub; also with no problem (outside of getting cold toes and learning about the disadvantage of metal zippers at such a cold temperature.)
