Maybe I have a lemon, but I can hear the spring ticking (rubbing against something) when I turn the cube. It's not loud, but it's there if you pay attention.
For me personally, RS3 feels sandy or slightly rough when I turn it. I guess it is a sign that it needs lube. (FWIW, MF3RS also has the same spring sound). I prefer YLM over RS3 because it is smoother.
