Corsair VS650 making regular grinding noise

[Tinfish]

Built my PC 4 days ago, all seemed to be running fine. Then the PSU started making a low volume, regular buzzing/vibrating noise that starts quiet and gets louder. I can fix this temporarily by giving it a slight thwack but this doesn't feel like a sustainable/healthy solution.

Build is as follows:
CPU: Ryzen 5 1600
RAM: 2x4gb Corsair Vengeance LPX 2666MHZ
MoBo: MSI Tomahawk B350
GPU: Radeon R9 380
PSU: Corsair VS650

Sounds like there may be an issue with the fan. A potential fix is to apply pressure to the center cap of the fan and push it back on the spindle. Also try running the fan facing up towards the ceiling and see if the issue remains. In either case if the issue continues, I would try contacting our Technical Support staff, and they can help you out from there.
