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.
  • 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.
  • Some Creality machines have been reported to have larger size metal screw standoffs. If your fan holes do not fit over them please see this article to make the fan fit correctly while still using the stock screws.
  • To use in the rear in a CR-10 Control box you can either use shorter M3x14mm screws or print a spacer. Stock is 20mm thick and these are 10mm thick. Download the spacer here.

    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 $.

  2. Gert Luyten

    Ender 2 note: make sure to purchase 4 x M3x16 bolts (so 4mm longer than stock) as you cannot use the stock bolts with the TH3D delivered fan. The stock Ender 2 fan mounting holes are deeper at one side to allow the stock bolts to slide in, the new Sunon fan does not have these.
