Hello, my problem is that I hear a buzzing electrical sound in my rig from quite a distance. I don't know whether it's my CPU, GPU or power supply unit. What I discovered is that when I run prime95 to stress my CPU, the buzzing sound seems to get louder. Also, when my rig is powered down, I can still hear the buzzing noise. The only way to eliminate this annoyance is to unplug the power supply from the wall.
I dunno but I think it might be my hard drive. I hear a whining sound coming from the hard drive area. LOL I think i'm paranoid because I don't know whether it's my hard drive or power supply making this noise. There is an electrical buzzing noise coming from the power supply but there is a hard drive whining sound.
LOL at least everything is now backed up. I'm prepared for hard drive failure.
I've located the two sources of buzzing sounds. The first one is my Coolermaster Hyper 212+ heatsink + fan. The fan's bearing is just noisy but I can live with that. The second source is the hard drive which makes a loud very high pitched whining sound which I can't live with. So I'm going to RMA the drive. The third source of sound which isn't very evident is the power supply which you can hear if your ear is up close to the case.
