Hello, I googled this title and saw no issues on that - i've just installed a brand new S5 (it was in the box for a year..) When the print head starts its fan/s a HIGH pitch noise fills the room and drives me crazy... i owned a Sigma R16 so i know about this annoying issue. Prints are very quit... but this high pitch noise cant possibly conform to an "office friendly" 3D printer. I appreciate any help/suggestions. Thank you Dizingof
