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.
  • 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.
• Noise notes:
  • In our testing and per the manufacturer specs these are quieter than stock fans based on dB measurements taken with a calibrated dB meter.
  • Removing and/or changing the design of the grill that the fan is behind will change the noise level that is perceived to your ears and it is subjective based on the person listening.
  • We only use dB meters to check noise levels. Most stock fans are 30-35dB in noise levels based on measurements of the stock fans from Creality, Tevo, and Wanhao that we measured here.
  • It is said that every 10dB increase in noise is perceived as 2x the loudness that a person hears (see here for detailed info on loudness and how it is perceived).
