Hmmm... interesting feedback.
To the first replier, I don't think it's the screen because the noise persists even when I turn it off.
I'm pretty certain the noise is coming from the CPU... or more specifically the capacitors.
This was a common problem with the Core 2 Duo's... the noise was much higher pitched than this though.
However, I was told that the Mini 9 was a perfectly silent computer as the Atom processors did not have the same problem as the C2d's. I was rather disappointed when I realized it as not as some people have told me, perfectly silent.
Given that someone also reported that he can't hear ANYTHING, I'm wondering if anyone else also has a perfectly silent Mini... or if maybe his noise sensitivity isn't as high as ours.
Thanks for the feedback!
