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 your 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
- 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.

Laronda –
How do I connect the new fan to ender 3? Would I connect the red and black wires that is still connected to the printer to one hole of UY connector and red and black wires from the new fan to the other hole of the UY connector?

Tim Hoogland –
The red wire from the old fan cable should connect to the red wire on the new fan and the same for the black. If you have any further questions on connection please check out our communities here: http://community.th3dstudio.com/

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 Hoogland –
The main reason people replace the fan is due to the stock one failing. While these are not as silent as the Noctua fans they will not cause heat creep like the Noctuas can cause. More airflow = more noise.

Charlie –
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.

We haven’t tried the Noctua 24V version (didn’t know they came out with them). But these fans are pretty quiet. You can also use the fan without a fan grille and it significantly reduces the noise from the air passing the grille.

Originally I wanted to use the Noctua fans because of how quiet they are but I didn’t want to deal with running overvoltage on a fan or having to use buck converters. These fans do the job just fine. Sure they may not be as quiet as the Noctua fans but these are plenty quiet.
If you’re going for a silent build maybe get the Noctuas but if you care more about the airflow and don’t want to deal with heat creep I’d go with these.
I’m about to order another for my mainboard!

The hotend fan I was using was sound original. It worked but it was getting on my last nerve sitting in the same room with it. While this fan is not absolute silent it is twice as quiet as that one it replaced. It is tolerable now to sit in this room while the ender 3 is printing. Quiet fan along with a board with quiet stepper drivers will keep you from going insane.

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 was hesitant to order one of these fans because of the cost over other alternatives, but after hearing how quiet this is, I’m ordering a second for my case fan. I’ve bought many cheap 4010 fans over the years and none even come close

For Ender 5 Plus users or others that don’t have have the silent board, these fans should be a 3rd upgrade. First, find a silent Creality board so the steppers are quiet–maybe one day they will just include it from the factory. Then you need to deal with the Meanwell RSP-500-24 power supply fan; that PSU fan is terribly loud when it kicks on and sounds like a server room. Note that at least some of the mods for the PSU involving large case fans do not provide enough flow.
After your PSU is quiet, then these would be a third upgrade.

Question
junaish –
For the cr-10s pro – there are 3 fans in the control unit. As mentioned in the description, this will go for the hot end and rear side of the control box. What about the other 2 fans in the control unit? One that requires a 3d printed mount near the board and the other being the power supply which is a 12v. Which should I go for? Also, if I swap the power supply fan with a noctua, 12v, is it ok?

Tim Hoogland –
As for the control box fan that is the exhaust the 40mm 24V will fit there as well as the hotend cooling fan. You can use shorter screws for the control box fan or use the printed spacer (or washers) to use the stock screws. We have not specced out a replacement for the PSU fan and recommend keeping the stock one for that unit, you would need to open up the PSU and see what fan is in there stock. Our PSU fan is over a year old and still working great (meanwell uses good quality fans in their PSUs) a Noctua fan (even their higher flow ones) may result in the PSU overheating as that is a large PSU.

I was impressed with how much better this made my printers (Ender 3 v2). This is the fan that is always running, and it was a very noticeable difference. I like the idea of the scotch lock being included so if you are not wanting to or comfortable soldering, you do not have to. Great fans!

Overall I am a fan of these fans. They are far quieter than the stock fans especially when using a printed hotend. My only slight complaint is the Quick Connectors were too finicky for me so I used electrical tape instead.

I have a Creality Ender 5 pro. This fan is as noisy even perhaps a little more as the stock fan. Maybe it is defective or perhaps the fan and metal cover combo crest noise. Not sure but I regret the purchase

The fan grill on the printer is what is causing the noise. It’s not the fan. You can easily clip the grill out with the side cutters that came with your printer. If you read the product page, we have this specifically listed.

Typically this is not because of the fan itself (our fans are quiet) but the design of some fan grills will make the fan sound louder than they actually are. See here for details: https://www.th3dstudio.com/hc/product-information/fans/fan-whining-noise-fan-shroud-mod/

Not sure if I received a different fan, but what I got was an Orion Fan OD4010-24HSS. This thing is LOUD. It sounds like a gaming laptop being pushed to its limits, definitely at the 35 end of the 25-35 db rating on the product page. It does push a lot of air though, and upon looking it up on Digikey, its actual air flow is 9.2 CFM (0.258m³/min), which I guess makes sense for how loud it is.
Edit: Looks like TH3D updated the product page and it now matches my review.

Hi there Jack, That is the correct fan and the noise is usually caused by some printers metal fan grills. In open air the fan is very quiet. I updated the product page to reflect the specs. The ones on there were from the 12V version and was not updated when we duplicated the page.

Its a fan, it doesn’t start screeching like a cat in heat after a few hours of use, and most importantly it moves air… you know, the one and only job fans are supposed to have. Are they quiet? No, though quieter than stock. A quiet fan means less air flow, less air flow means your stuff is getting hot. Never good on a hotend or with electronics. If you want silent, take up a hobby like knitting.

Got these to replace the stock noisy fans on my Sunlu S8. They work great but honestly, they seems to be just as loud but moves more air so it’s still a good purchase.
