I want to know why E3D use to 30mm fan? Is it just to make the whole package more compact? The reason I ask is because I could no longer take the noise of the 30mm fan, so I printed this fan duct http://www.thingiverse.com/make:145230 and have swapped over to a much quieter 40mm fan. Thx
The Lite also uses 30 mm, but it is not as loud as the power supply fan. However, there is some kind of intermittent buzzing sound from the extruder area that comes and goes, and it seems to come from the fan (when I touch the fan to slow it down, the buzz stops). Probably just a loose fit to the heat sink.
