 |
|
I recently took my VA-503+ out of service, but while it was in service
(in an ATX case), every time I shut down the PC, I kept hearing a high
pitched whine. Initially I thought that it was the power supply in the
case.
After we got new PCs a few weeks ago, I took the 3 socket 7 systems we
had and took the best remaining parts from each and made createda single
socket 7 based system for our third machine.
I put another board in that same case with the same power supply, and
when I shut it down now, there is no whine, so now I am assuming that
something (capacitors?) was starting to fail on that board or perhaps it
wasn't happy running with the ATX power connector (even though it was
configured for it).
Sound reasonable?

It could be other things. If you look at the forums at
http://www.silentpcreview.com , you may find posts about "coil whine".
It is often an interaction between the power supply and some other
component, such as the graphics card, a hard drive, or the motherboard.
The parts are not necessarily bad, but the combination causes a
whining sound that can sure be annoying. It is quite possible that the
same VA-503+ with a different power supply would be totally free of whine.

Thanks for the link. Very interesting site. Some interesting ways of |
dealing with noise too.

Yes, annoying is the word...I suffer from very bad tinnitus, and the |
whining was worse than that.

I do have a spare case that I can use. I need to set a machine up again |
anyway, simply for the purposes of getting the heatsink warm enough to
attempt to lightly twist it off of a k6-2 500 that the vendor I bought
it from decided to glue it onto the CPU...but that's another story :)
Thanks again...Brad |
