Noise inside case

[Hans L]

I have a minor noise inside my case. It is a new noise. As I am about to open the case to try to locate it, it strikes me that the human ear is not the best for pinpointing sound locations. Does anyone have any advice on what kind of implement one can/should use to put to the ear and stick in there to locate a particular sound? Or does there exist something sophisticated with amplifiers and stuff?

Grateful for any suggestion.

Disconnect 1item at a time until the hum stops.

unplug each fan one at a time first then see which one.

Hokay, the teadious way :-) I though you would suggest a stethoscope or something. Okay, I'll do as you suggested. Seriously, thanks, guys!

The old way was to use a rolled up magazine, to act as a stethoscope (at least that's how I do it.)

That must really have been the "The old way", Vinny, when computers were LARGE. Now, you can barely get a rolled-up sticky note paper in there:-)

The perfect thing would be a flexible, electrically insulated and anti-static, thin hose (that stays bent the way you bend it), with a listening device at the end. You know, endoscopes must be of this kind (you stick it down the throat, into the stomach, and then, you can move the tip in various directions). But instead of an ocular in the end, you have an ear piece.

Now, the funny thing with this noise is that it is not constant. I bent the graphics cards ever so slightly yesterday , and the noise at least changed pitch. So, it is probably the fans there. (Boy, these nVidia cards – I'll go for any other technology (ATI or Maxtor's) next time.)

Thanks for the magazine tip, Vinny. It may lead to something smaller.

u can use rivatuner to change the viddy cards fan speed, that should help pin it down to that or not
