Maybe louder than the quietest airplane ever made. The S3 is probably the quietest miner yet built, with the possible exceptions of what, New R-Box and maybe Avalon4 in certain configurations? Leastways it's the quietest of the S-series and can be made almost silent.
this is very true lol
the S3 was extremely quiet.
I was very surprised a million years ago when i had a bunch of them
thanks!
