All excellent explanations guys. I'm glad I'm not insane and others hear these noises to. As for my VRM squealing charlie I'm wondering if it stopped because another vibration quelled or canceled it (my fan increase). just to many damn variables to account for every possibility I guess but who cares why it stopped really. I love your idea about the eraser sswilson that's a keeper. One thing I often wished for was some sort of sound measurement tool that could reach into the tiny nooks and cranies of a computer case to pinpoint those aggrivating sounds which I'm sure we've all had before. I've tried two approaches, one is to take every part out of the case and test each one at a time. Secondly I've just learned to ignore the sound haha.
Ohh on a side note here. Everyone know those little rubber fan mount/pins (vibration isolators) I LOVE THOSE THINGS!!

These lil jewels really quiet fans a lot and I want more! They're DAM GOOD
