Installation notes

  • Make sure to connect wires with correct polarity to the fans.
    • Red is positive (+) and black/blue is negative (-) for the fan wires.
    • The fans have reverse polarity protection, meaning that they will not be damaged if connected wrongly.
      • The warranty is not covering damages to the fans caused by improper wiring.
    • Using the JST-XH connectors:
      • The mainboard and PSU fans are ready to use. Just unplug the old fans and plug in the new fans.
      • For the hotend fan you need to extend the wires.
      • Important!: Make sure that the polarity on the new JST-XH connector is the same as for the old fan. If needed, swap places of the red (+) and black (-) wires in the new fan JST-XH connector to match the old fan connector (use a small pencil/knife and push down the metal piece near the front of the connector, then pull the wire out).
    • Installing the hot-end fan:
      • On some 3D-printer models, the metal screw standoffs can be a bit bigger than the screw holes in the fan. To fix this simply use a knife or scissors and round out the four holes facing the standoffs in the fan.
      • For an even quieter fan, cut away and remove the fan grill in front of the fan.
    • General installation instructions:
      • Remove the old fans and cut the wires around 3-5 cm from each fan. Make sure to leave some room on the wire to be able to strip it.
      • Connect the new fan to the old wires using one UY-connector for each wire (i.e. red (positive) fan wire to positive 3D-printer wire).
      • The fan blows in the direction of the label on it. The label on the fan should be towards the hotend/board (not facing away).
