Glad to hear the IIci floppy bracket was a good fit!
As far as fans, I'm not sure how it would fare over time without one. I too enjoyed listening to relative silence when I was testing the machine prior to shipping. If you're handy with connectors I recommend pulling one from an original LC, as the brand they used in there (which I don't recall off the top of my head) was quieter than the Elina Fans commonly found in later LCs. There's also a DC Pico that works in the LC but I have never used one for an extended period of time so I can't comment on their noise. (Note that you'll need to re-do the connector if you pull from an original LC, as it had a different assembly than the LC II/III/475).
