Is there a loud grinding sound coming from the power supply unit during the startup of your PC?
A couple of days ago I powered on my PC as usual and immediately noticed a very loud grinding sound, which I'm 99% certain is coming from the PSU (EVGA 600w Bronze). This occurred again today, so I looked into possible causes such as coil whine, faulty bearings, a failing fan, or a wire touching the fan blade. The main reason I'm writing this is that this strange noise consistently happened right after booting. After turning off my PC and restarting it overnight, the sound disappeared completely. It didn’t occur throughout the day. Anyone else have experienced this problem and found a solution?
From the description, it seems like a fan bearing. Not unexpected; the 600W Bronze EVGAs (B1, BR, BQ, BA) are all made quite cheaply and with average quality, which makes it understandable that a fan would be needed.

Heres a link to the sound its making
I've maintained and greased a few PSU fans. It seems there might be a way to extend their lifespan. Swapping the fan would be an option, but you'll need to understand its voltage, current, and airflow specs. (It's more cost-effective than replacing the entire PSU.)
