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
- 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).

Part Fitment/Installation/Wiring
This is a universal 3D printer part. That means it will work on almost any 3D printer. Electrical 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.

I had previously done the Noctua A4x10 FLX swap on my Ender 3. It was stupid quiet. For most things they worked great, being less than 1 cfm off of desired spec. But on longer prints that 1 cfm would rear its ugly head on the hotend, leading to heat creep issues. These fans are obviously louder than the Noctua’s but man they flow some air. The fan slipped right into the case fan mount with no issue, and now is running full time as the noise is bearable. On the hotend side, I did have to do quite a bit of reaming and fitting to get it in there (odd as the Noctua was a drop in for both locations, physically). I actually ended up distorting the fan chassis a little, but it’s working with no rubbing. If you don’t mind doing a little work to get it to fit, you’ll be happy with these. Side note, the stock i received were not the TH3D branded units discussed on the live stream, probably still working on the old stock. Overall, I’m still happy with it.

I bought two of these initially with the ideas of quieting the Ender 3 on my desk and after the hotend fan starting making noise that sounded like it was potentially going out only a couple of weeks after building the printer and finally getting into the hobby. After swapping the controller out for the EZBoard Lite, the stepper motors were way quieter than the fans so I figured I these would be the next thing “upgrade”. Initially I was dismayed when I installed these because they seemed louder with a higher pitched whine. I figured that can’t possibly be right (especially, after seeing other reviews). I started to wonder if I had a bad set of fans, but figured it was unlikely both were bad. It was mentioned on one of the other reviews about that noise might be from the fan “grate”. After some experimenting I determined that on their own these fans were whisper quiet. Sure enough, the noise seemed to come from increased air flow across the grates. The “fix” (way less noise and no more “whine”) I went with was (4) 4mm washers on each of the posts that the fans mount on. I needed slightly longer screws for the hotend, but was able to use the ones for the controller board fan. These move seem to move quite a bit more air than the cheaper stock fans so the slight shift of fan doesn’t seem to hurt at all for the airflow. Alternatively, I had considered clipping off the sheet metal and using some 40mm wire fan grates. I still may if I get ambitious, but I had the washers and longer screws already. Swapping these has definitely made my printer quieter.

I purchased this as a quieter replacement for my Ender 3 motherboard cooling fan. There was a very small reduction in noise compared to the stock fan, but not worth it.

Tim, would the Noctua at 24v move more air? People are reporting hundreds of hours with this setup. I want the easy board but I’m sick of fan noise and don’t see the value of quieting the steppers when my fans are loud. Add to this I’m running a v6 and need one 30mm and I’m in a pickle. I can’t find a single quiet 24v fan. I’d do buck converters but now I’m worried about Noctua moving enough air.
