I am about half thru printing this 2+ hour print job with the gyroid fill & the printer sounds pretty normal. I did hear a strange noise when in the other room, but think that was a woodpecker outside pecking on something other than wood.
I have just been putting these different versions of the slic3r in separate folders, so I can easily go back to another version if I do not like the current. Think I can get rid of some of those folders now as I just realized I have 10 separate folders now. I too, have not had a need to go back to a previous version yet. I have only used the released versions so far.
