I have an EVGA P850W and it’s absolutely the loudest thing in my PC because they used a cheapest fan they could find, I want to put a good silent 140mm FAN.
So what should I do before I open it ? Discharge it couple of times by pressing the on/off button? Leave it to inactive for 24 hours to make sure it’s discharged? Don’t touch any capacitors when I open it? Wear thick rubber gloves? Wear rubber boots lol?
