btw I've also a Corsair VX550 which I used for 7 years non-stop 24/7 on a server (now I keep it as one of my backup PSU's along with a Seasonic) and the fan is a DBB not noisy and show no sign of age ... if it was a FDB fan would it have last that long?
True FDB has anb MTBF much longer than any DBB. Your sources are incorrect as they may be thinking of "fake" FDB that are actually just rifle bearings:
