Installation Notes:

  • Be sure to check the polarity on the wires you are connecting our fans to. Typically red is positive and black is negative but some of the Chinese printers do not adhere to these standards.
    • There is no list of what machines use what as it can vary from model to model and we have even seen differences in wiring colors used in the same printer models.
  • Our fans use red for positive and black for negative. You can verify polarity with a cheap $10 multimeter from Amazon or you local hardware store.
    • If fans are shorted out/killed due to improper wiring this is NOT covered under warranty.
  • When replacing a fan you will want to splice into the existing wire to your existing fan. Connect the wires with solder and heatshrink OR use our Quick Solder connectors.

    Replacing the stock fans with this fan coupled with the other two really quieted down the fan noise from my CR-10 control box which was really annoying. I recommend buying the kit of three and saving some $.
