It's not coming from the hard drives.

I haven't seen mentioned the fan on a video card..... That was my
problem.

I just had/have much the same thing. The 'buzz' would go on for some
minutes, then fade away. I opened the side panel on my Gigabyte Aurora
3D case and started touching stuff to try and find the buzz. It was in
the front of the case, I'm pretty sure. I wanted to unplug the 3 case
fans but plug is buried under some USB connectors at rear of
motherboard. I did unplug the big 500G secondary hard drive - no help.
The CPU fan and video fan definitely not it. Power supply? unknown.
My biggest suspect, the front case fan is pretty unaccessible, I'd
never had the front panel off. Looked like it was just plastic clips,
but he damn thing RESISTED. Eventually I loosened up the various
drives that stick their little faces out thru the front panel, that
finally got the thing to come loose all the way. I still didn't take
it all the way off. I researched some 120mm fans at NewEgg.

And, after all that fussing, the turn-on buzz has disappeared, at
least for now. But at least I now know I CAN get that damn panel off
if I want to.

The screw are tightened correctly.

I put my finger lightly on the CPU fan and there was no change in
noise level.

I'll just play some disco music and drown out the noise. :-)

I've never seen the CPU fan cause vibration. *I would be looking at
case fans.

I believe I replaced the CPU fan from a box of salvaged items.

I think the newer fan is too fast, thus the vibration.

I put my finger on that fan like the others.

Is the newer fan a 2-, 3-, or 4-wire fan? If it's anything other than a
2-wire, it should be able to be controlled, either manually through a
program like SpeedFan http://www.almico.com/speedfan.php , or
automatically by the MB.

I have. My SO had an eMachine years ago that would give her fits about every 6-7 months because the case would start
"buzzing." You could hear it and feel it in the case. My first thought was the rear case fan (nope, not it), and then
the PS fan (nope, not it either). Turned out it was the CPU fan. It was an old Pentium II with one of those tiny Radio
Shack POS fans, and the bushings would wear out regularly. At the time, it was all she needed in the way of a PC, and it
was a heck of a lot cheaper to buy new fans ($4 or $5 at the time) than it was to buy her a new PC.

Understandable for an eMachine. I've only dealt with one of those. We
normally had decent equipment.

I've seen some cases like that, a total pain to get at the fans in the
front.

The fan usually fails on my graphics cards and I don't smoke. You
should see the cards I pull out of my sister's machines.

Almost everything I've worked with has been from non-smoking
locations. I do agree smoker's machines are miserable.

Thanks for the idea. The fan is a 3 wire.
