I have excellent hearing, and I realized that the sound that I'm hearing might probably just be a normal bearing noise. *embarrassed self-facepalm* Since I can't really have downtime on my PC at the moment, I'm not going to do an RMA unless it becomes an issue.

Thank you for offering your assistance anyway Jonny. :-) However, may I DM you my feedback/comments on how the PSU interacts withe the Carbide 100R Silent edition case please?
