I was told there were two reasons to have a fan mounted there: 1) To keep the extruder insulation cool (don't want it to get *too* hot) and 2) to cool down the plastic immediately after it has been extruded (especially useful on small prints that would normally require slowing down or else get mushy).
This is pretty cool and simple, but how does a fan help exactly? I've been trying to find info on the advantages on having a fan, but not sure if it's hooked up to the RAMPs board or what... Anyone have any guidance on this?
