Silver Swan S Vintage is our 2nd Vornado purchase (first being a model 660 for our bedroom which is truly whisper quiet at low speed and we absolutely we love!). Our satisfaction with model 660 moved us to look for a more decorative style Vornado model for our living room (14 ft x 14 ft), daytime use, quietness not as important.
We like the metal workmanship of Swan S Vintage, it’s a pleasing decorative piece in room.  We purchased knowing it’s noise level is slightly higher than 660.  I only operate at low speed and it’s noise level is reasonable quiet at low speed (mild white noise), classic tone of this style metal blade fan.  Oscillating mode, (though I rarely use), has been pleasantly quiet without any mechanical noise from components.  Though only owned for 1 month, I don’t see any reason not to expect years of good performance.
