Unfortunately, it is the Elina Fan I find too loud. I'm actually working on a project similar to Ze Cube but with an SE/30. One of my goals is to make it very quiet, if not silent.

P.S. To reduce the analog board size, is there a way to rewire the brightness control nob from the analog board? Could you just dremel a bit to reveal the copper and then solder wires to the board? Without the nob, the board can actually be trimmed by about 50%.
