Answer 1

What you're describing doesn't sound like fan noise to me.  At 3597 RPM, your fan is spinning at about 60 Hz.  Typically a fan noise will sound like a low hum or buzz, and a failing fan, in my experience, sounds kind of high-pitched, but not what I'd describe as very high pitched.
If, on the other hand, what you're hearing is a very high pitch whine, then you might be experiencing something similar to what's described in this thread:
terrible whine noise!
