What hardware is making too much noise?

Michael Peter · Dec 10, 2014

I am kinda afraid what component is making sounds, cause sounds can mean failing hardware.

The sound is usually high on system startup and it goes high randomly when the PC is on.
I fear it could be my hard-disk; and i do not want it to fail again.

How can I find out what component is making the sound? I have Corsair PSU 450W, AMD Phenom X4 955BE, Gigabyte 880GM USB3 motherboard with onboard ati hd4250, and 1 TB WD blue hdd.
I used system monitoring tool but couldn't make any sense out of it.
And I highly doubt if it is my CPU's cooling fan, cause it's sound is different, which can be heard when there's some high processing going on.

Usually, noise comes from a fan running at high speed.

Use a paper tube as a stethoscope to your ear and the other end at possible noise sources.

Or use your fingers to touch each part (unless it's something hot like the CPU heatsink, which doesn't even make sounds anyways

).

I have 2 fans on the cabinet, of which one cannot be seen, cause it's located near the power button. Other is inside the PSU and one on the CPU. I'll try this method.

zeyuanfu :

I'd do it, but is it safe? Won't there be current charge on the components?

If you`re worrying about getting electrocuted, unless you open up the PSU and touch everything in it, I highly doubt you`ll get a shock.

Sorry, couldn't find time to open and find what's it like in there, but for now I got a recording. It's not very much clear, but it sounds like this: http://puu.sh/duk2X/ac76a01f98.mp3

PS: This is not constant; this high-low-high-low sound comes randomly; and most of the times when I boot up my PC.

That sounds like a fan of some sort, although I can't be sure.

Narrow it down through process of elimination. If you think it's a certain case fan, disconnect it and see if the problem continues.

RazerZ :

Okay, I tried that and it mostly feels like it is the PSU. Cannot be sure since this sound didn't come easily and it is random.
Can PSUs make such sound? If yes then what situation could it be?
