 I have a feeling I have crap luck with the Vortech's. I have been through 3 (2 on my old build then sold, then my current one) and they were all fairly loud to my ears. Either that, or I have super-sensitive hearing?
I hear people lucking out with quiet ones out of the box, or they 'break-in' after a few weeks of use; just not my experience sadly. If anyone is unsure about the QD though, it is well worth the upgrade if you can't stand the noise of your Vortech.
