As the title says, I built my pc outside my case to test all my components before putting them in my case, and when it finally all powered on, I heard a LOUD grinding noise from my power supply. Peaking in with a flashlight, it looks like the fan blades are..somehow.. grinding against what looks like the frame for the back side of the fan. I havent opened this power supply even once before, and this is my first time powering it on. Looking online, i havent seen anyone else with this problem on this specific power supply, so its really odd. Im debating getting some torx and opening it up and notching the frame instead of RMAing it, as it would probably take ages. What should i do?
