I have a seasonice 620w power supply fx 8350 and gtx 680. When I play games I notice my power supply fan starts to spin up pretty fast and is sometimes the loudest thing in my computer. I notice the air coming out of it is pretty warm. When my psu gets warm and the fan spins fast does that mean my psu is under a high load? And if so would getting a bigger power supply help keep my case quieter because it will stay cooler or something?
