That is fantastic, thank you! It's not so bad I considered replacing it - almost nothing short of complete failure or battery death will prompt me to buy a new one - but it'd be awesome to fix the noise issue.
I didn't even think about looking for a fix. IME, they're basically glued together, and I didn't consider they'd have any accessible screws.
