I`m considering sending back to Logi anyway, as I`ve got a duff microswitch, but I can`t say the excess noise is much of a problem. Yes it is louder turning left than right, but there`s no "feeling/grinding" change in either the turn or the FFB for me, whether it`s set to 360/900 or whatever. The only time it`s really a bother to me is at 4 in the morning, when the girlfriend`s asleep 2 foot away, and I hit either T3/4 at SO Sprint 2 (the quick left/right) or FE Gold/Black - T2/3 (same). That`s when I get that noise noticeably on both turns.
I still wouldn`t consider giving this thing up at all, I love it. It`s precise, stable, I`ve been deliberately looking for the slightest microscopic off-axis wobble or misalignment from the steering/pedals, but it hasn`t happened (it`s pretty close tolerance metal parts, not bendy-ass plastic)
Yes, the noise can be annoying at occasional times, but I know several people with M$ sidewinders, or DFP`s, that suffer much louder noise all the time, so it isn`t that much of a deal to me. YMMV.
Cheers.
