Geeetech Silent Prusa i3 Project

Replace the original fan with an Blacksilent fan. This fans has 2800 rpm and only 9.2 dB/A @100cm.

Air flow is slightly less than before, but the heatsink still stay cool. Use the original fan for layer-cooling (see picture 1).

You can do a additional reduction of fan noise with the brackets too. If the fan is too close, there is noise from airflow on heatsink.

See the video for a quick measuremt of the result of modification.
