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.
• 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.
  • Fan Mod Article: Fitting Fans to Creality Machines – Larger Metal Standoffs
• 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.
• Ender 2 Control Box – 4x M3x16 Screws needed as the stock fan in the control box has recessed screw holes.
• On some printers, the metal fan shrouds can amplify the motor noise of a fan. This is usually seen on the Ender 3/5 series with their metal fan grill that comes with the machine. The grill itself is easy to remove and takes only a few seconds to do. See this article for details.

DIY Part Fitment/Installation/Wiring

This is a universal DIY 3D printer part. That means it will work on almost any 3D printer, but you must know what you are doing.

Our technical support does not cover selecting/designing/assisting in firmware setup and/or 3d models to install this part on your printer. If purchased as part of a kit from TH3D for a particular printer, then it will be covered under the kit when using our firmware package.

Electrical replacement parts usually will require you to splice wires into your existing ones for the part you are replacing (soldering and heat shrinking wire splices is recommended for proper connection).

Some of our universal electrical parts come with bare wire ends or plugs on them. These ends may or may not directly plug into your 3D printer. If they do not, you will need to splice the wires into the existing ones on your 3D printer.
