I've found a cure to my 'CPU whine'.

I recently picked up a wonderful deal on a mint condition 2006 MBP but was distraught to find that it had a high-pitched electrical and non-stop whine coming from the top left corner - at the magsafe connector (really enough to drive you insane).

Anyway; after surfing the forums, and putting in some research time, I decided to download this little angel. My MBP is now quiet as a mouse.

I got my friends to listen for the whine and they seemed not to hear it as much as I could; I do have to wonder, can only a percentage of the global population hear that frequency? Bizarre.
