   If you're talking about a very high pitch like that of a monitor left on
when the computer is turned off (alot of people I know can't here that but it
bugs the hell out of me), then my SE/30 does it sometimes too.  It seems to 
be very directional (or maybe that's because it's so faint)  I did notice that
pulling down a menu makes it go away sometimes.  Yes it's only at idle time
like you said.  I haven't checked whether it's particular about multifinder or
not.
  My guess is that it is some kind of monitor noise because that's what it 
reminds me of.  I think it occurs when the screen is idle, ie. it doesn't seem
to do it when the screen saver (Moire) is drawing on the screen.  If you
ever figure it out, let me know.  Maybe having a little window to the side with
a constantly changing shape in it (force the screen to always draw something 
new) would make it go away.
