All the heatsinks where a 140mm fan makes sense on, are very similar to the Archon in that regard: Silver Arrow SBE, True Spirit 140, Phanteks 14PE, Noctua D14, Prolimatech Geneses, NZXT HAvik 140, ...)
I don't know, i have still around 10x TY-140 laying around here, and all of them made a more or less audible bearing noise at low rpms, and i'm talking bearing noise in open air. Maybe it's just the difference in perception...
listen to the samples here for the A15 & TY-140 (right side is the sample @ low rpms) and you might realize what i'm talking about:
And for the record: i think the TY-140 is a great choice for a lot
of people: if one is not particularly sensitive to these aspects then i'd always recommend the TY-140/147 before the A15 due to the more reasonable price. Above i was solely talking about the fan itself without looking at the price at all though.. ^^
I'd take the TY-140 really...you run your fans open air for regular usage?
Now if you have an externally mounted radiator and a super sensitive ear, I recon you might hear something, not sure how disturbing it will be though.
I can't notice the noise of a less than 1300rpm TY-140 inside of my CM-690, even when put against the mesh as intake. Being a musician with hours and hours of band rehearsals might have made me more tolerable to uber fast fans perhaps
