Just to do an update on what is going on:
I sent in an RMA ticket and as I guessed I am working on the old warranty of the power supply they replaced prior (which I don't have anything against, makes sense). The mistake on my part though was when they originally sent the notice, they informed me that I had to include the invoice, I figured since I was getting a replacement I didn't need my original invoice so I sent it in with my only copy
So this time around OCZ asked for that original invoice and I informed them of what happened and they said they'd do the RMA anyway
. Even though it will be "this one time only", that's fine since I am pretty sure my original 3 year warranty on my old power supply is coming near its end (purchased in 2009).
So yeah, everything worked out, hopefully they'll fix the noise issue or they'll replace it with one that doesn't have that problem. Now the only thing I'll have to worry about will be getting my hands on a temporary power supply.
