How exactly does this attach to the print head? I have a similar i3 clone without any obvious attachment holes to add a fan, looking for some novel way to add one. Thanks!

hi, should the fan be always running? i connected it parallel to extruder fan wires, is this ok?

It should be okay, though the first layer bonding might not be optimal, and ofcourse it's always nice to be able to adjust your fan speeds
