Most printers have two fans on the head. One to cool the heatsink where the filament enters, the other to cool the filament as it is extruded. A very common upgrade is dual fans for filament cooling, and there are a slew of different designs for most printers. I bought dual fans to upgrade, but have yet to print the new duct to mount them. I also bought a new, larger fan for the motherboard, but never got around to installing it.
Full of ideas, but slow to produce parts
