Hi All
I recently added two additional FANS to my case. I had none before and my temp stay low enough but since summer is coming (live in NZ) and though it is better to be save.
Since I have added them my speakers pick up a buzzing sound interference, and it only happens when the volume is set to the start 1/4 region.
So only when it is fairly low volume level.
It picks up this  interference all the time even if they are not working, only need to be turned on.

My speaker info: Logitech X - 530, surround 5.1

You may want to use some hints from this web page: http://www.epanorama.net/documents/pc/soundcard_tips.htmlJust a little check...MAKE sure the green plug is all the way in I get the same with my logitech r-20's when they're not all the way im...also, mute any devices not in use, (Mic, line in, AUX, modem, etc)

Hope this helps
