Human: A Better Stock Cooling Solution There's no reason to add a second fan because the stock fan is sufficient if the bracket was designed properly. This is the design that should have been on the Da Vinci. If you look at the image of the stock fan mount, you'll see it blows straight against the top of the tube and not directly onto the heat block, leaving sides open so it blows straight out and hits the other side, bouncing back to just blow the same air out the sides of the fan. This design blows directly on the cooling fins and block and since it's angled more down than straight, it blows air down around the heating block and onto the bed, helping keep upper layers of your design heated for better adhesion to lower layers. Others are making fan housings and adding extra fans, but I think this is a bad idea all around. Adding a second fan to blow on the heat block cools the filament as it exits the tip, so layers won't adhere as well. People do this, but I believe using two fans like that solves nothing and creates more problems for XYZ printing head issues.
