Is the Seasonic X-750 supposed to make this noise?

Mine is making a similar noise to my Enermax Modu82+, I would describe it as like there was a tiny bit lack of oiling inside the bearings. It's not smooth, there's this pulsating grating noise when it's spinning (not loud though). Am I just being picky or what since it's almost like the Enermax?

My Enermax Modu82+ 425W does not sound like that. I would guess the fans are damaged.

Try turning the PSU upside-down and see if the noise is still there...

To me the noise is not normal....
