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 to 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.

    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 $.
