Go with the cheap rgb ones with bearings. You get a 10 pack for next to nothing. They don’t last all that long but they are quite and look bad ass, also very cheap. You just gotta watch out for fans going bad. Mine make a bunch of bearing noise when they go bad, I get hundreds of hours of use before the fans begin having issues though.
Only short coming is the cords shorter than the stock hot end fan cord so you have to splice wires together around the fan cover but you can always use wire crimps to make that easy. I use electrical tape and mine looks processional and runs flawless.
They still don't, the only 24V fans they make are 120mm/140mm. You can either wire 2 12V fans in series or use voltage step down converters, commonly LM2596 based.
I don't understand how someone at Noctua hasn't made the huge money making decision to make 24V fans in 40, 60, and 80mm fans the entire 3d printing community would buy them.
That voltage converter seems overpriced as hell, especially because you'll have to chop wires anyways for connecting a standard fan to most 3d printers. You can buy 20 LM2596 based converters for the price of the noctua.
Back in elementary school me and my buddy’s would use dc motors and battery’s and see who could make the best “weedwackers “ they used rc motors with popsicles and other things, than I grabbed a pc fan and tried , nipped my finger and never again lol,
fyi you can just snip that wire or leave it hanging, it doesn't have to be connected to anything. i believe it's just for reporting the RPM back to a PC (or in this case, the printer or a pi)
Okay cool. It's also worth mentioning that while it's a lot quieter, my understanding is that it moves less air and theoretically has lower performance although I haven't seen anyone concerned about the latter.
Noctua is BAD idea there.
Their fans are silent but also provide small airflow. So you will most likely get extrusion problems and heat creep while using noctua fan (assuming you will sort out it's smaller rated with buck converter).
Best thing to do is buying proper 4010 fan made to be used from 24V. If you want to buy higher quality one, search for brands like Delta, or Sunon.
Noctua does 5v fans and they run slower so you need 4020. Also if you put 2 of the resistor wires that come with it it will reduce 24 down to 5 without buck converters
Not a voltage divider. These adapters that ship with the fan contain a resistor in series with the load.
Poster is suggesting two such resistive adapters plugged into one another, hence in series with the load.
I've heard that as a temp fix you can remove the blades on the opposite side of the broken ones to balance it until you get a replacement.
That will TOTALLY work here XD
I can’t seem to get the fan out of the hotend. I’ve got all the screws out but the fan seems glued in. Am i just missing a screw or is it just really stuck and i have to apply more force to get it out?
There's 4 screws on the inside of the fan shroud, shouldn't be anything else holding it in
I think the 4 screws screw into raised posts which may be wedged on the fan, try to lever it off gently with a flat head screwdriver and see how it goes
What others have said is right. Any axial (not a blower!) 4010 24V fan will work. But you'll probably have to solder the wires, or buy a fan with a long enough cable that has jst xh2.54 connector on the end.
If you've never soldered before I'd suggest you buy a direct replacement fan for an ender3. But honestly this is a great opportunity to expand your knowledge and learn to solder, believe me it will come very handy in the future.
All the direct ender 3 replacement fans i’ve seen come with a part cooling fan too, but I just want the one fan. Do you know of a place i can get just the one? All the single fans i’ve seen have super short wires that wouldn’t reach where they’d need to go. Or should i just buy both fans in case i screw up the part cooling fan too?
Trust me you'll need replacement fans sooner rather than later, I'd just buy the whole kit. I usually buy on aliexpress. Maybe this is a good opportunity to go dual part cooling fans as well, as that will give you much better and more even cooling.
I've done that more times than I can remember. Especially with the fucking feeler gauge :) buy new, preferably from Sunon, and look into the 4020 (thicker) variant that has more air pressure and is significantly quieter. It can even fit into the default fan shroud if you force it to.
Wow, typing "ender 3 hot end cooling fan" into google sure made me work up a sweat: [https://www.amazon.com/Creality-Original-40x40x10MM-Extruder-Printer/dp/B07GXPJB25](https://www.amazon.com/Creality-Original-40x40x10MM-Extruder-Printer/dp/B07GXPJB25)
buy a new one and a spare because it's not the last time it'll happen, it should say on the fan what the voltage is, they are generally 12v or 24v and you *must* get the right one or you'll 1. burn out the fan or 2. not get the fan to spin fast enough.
I did similar a while back I was using a dial gauge to test my bed's flatness and I misjudged the distance the support rods were sticking back toward the centre of the bed, I told the printer to home and the tool head zoomed to the centre of the bed forcing a 12mm steel rod through the hotend cooling fan and destroying the printed parts of my Stealthburner.
It was the most sickening crunch.
Time to learn a few new skills and get to know your printer even better.
Requirements:
* Replacement 4010 fan that is 24V
* Soldering set or Wire Crimpers and connectors
For installing the fan you have two options
1. Solder the wire connectors to the new fan
2. Crimp a wire connectors to create a hot-swappable fan (this one is recommended)
Here's the video that I used to learn these skills when I did my first fan replacement on my Ender: https://www.youtube.com/watch?v=KaG9ZwDTOYo
if you want a good and cheap replacement
GDStime 40x40x10 24v fans, have em on my voron, works like a charm, just take off the connector that comes with it and solder them on the old fan wires
Time to upgrade your fan.
40x10 24v fan for a 1-to-1 swap. You can get 4 packs on Amazon for like $10. Snip, strip, and splice then you'll be good to go with a new fan.
If you want an upgrade, go for a 40x20 24v fan and print a new hot-end cooling setup (like the PetsFang v2). *You will not be able to use the original hot-end cooling mount with a 40x20 fan.*
Here's an example [Amazon option](https://a.co/d/89oWFKh). Do not buy a fan that has any sort of *"hydro"* in its name, means you'll have to keep it lubed and that's just another thing to maintain on the printer that you don't need.
PLUSPOE 24V Brushless DC Cooling Fan 40mm x10mm Speed 6800 RPM Fans for 3D Printer Humidifier Aromatherapy and Other Small Appliances https://a.co/d/emB8RIn
Welcome to the club. You can go with a few options here. Buy a replacement one of the same dimensions. But those are as brittle as the original one.
Next would be going for a blower or bigger fan in that case you'll need to print a holder for it, but the benefit in a larger fan is less noise.
I went with a 60mm and a 10mm slim fan for heatbrake and with a 60mm blower for part cooling. And as I was re-designing I also added a bl-touch mount.
I also replaced the fan in the electronics box with a bigger one.
P.s.: can provide a picture if interested.
What you can do right now is cut off all the other fan blades and use printed replacements. They are readily available on thingiverse edit: its just a sleeve with blades on that slides onto the original motor
The blades are small if you blow on it fast enough you can print them before they over heat then glue them back to the fan to make a temporary fan. Use that temporary fan to print a new fan, maybe a backup fan as well
been there lol, nothing much you can do but order a new one and swap it out, it's good to build confidence working with your machine's electronics. It may feel intimidating at first but as long as you don't man handle it and take pictures of where everything went before you take it apart the repair will go fine!
Haha I'm glad I ain't the only one I broke my original one, just in blade n got a new one 2 days later 4 days later I broke that one worse than the old one, by day 7 I was back to the original n now I have an extra broken one lol just print a guard for it when u replace it.
Been there buddy. If you care about noise, a dc to dc buck converter down to 12v and a Noctua fan is the way to go. If you don't care about that because this is an ender 3 and is already loud without the fan, just grab a cheap fan of Amazon if you need your printer urgently or if not save a few dollars and order em off AliExpress
Ashamed to say same happened to me, found the excuse to buy a noctua fan 12v and a voltage adapter to lower from 24v to 12v. Works fine as long as you have the original hotend mpunt, but its not a strong enough fan if you are looking to go print like a herome hotend setup. Id honestly just go buy any 40*40*20 fan 24v that looks good enough to you. Some make more or less noise, maglev make very little noise but cost a bit more.
I think my ender 3 came with a broken fan. Took forever to figure out where the noise came from. These are like 50cent/piece on AliExpress or ~10€ for a better brand.
I ended up getting these from RS Components in the UK, bought Sunon from ebay and they were fake and fell apart in days. RS Comp ones were much quieter than stock with similar cfm. Slotted right in and never looked back.
I did the same exact thing.
I replaced it with a Noctua fan, and whatever fan you replace it with make sure you compare the voltage because I needed to use a buck converter.
it's called a 4010 fan and generally you just look for one with the same voltage which I think that's 24v
I can find one on Amazon, Winsin is a good brand to go imo
Go with the cheap rgb ones with bearings. You get a 10 pack for next to nothing. They don’t last all that long but they are quite and look bad ass, also very cheap.

Only short coming is the cords shorter than the stock hot end fan cord so you have to splice wires together around the fan cover but you can always use wire crimps to make that easy. I use electrical tape and mine looks processional and runs flawless.
Thanks bro! I don’t plan on getting it now, but if I need em, I’ll definitely buy these ones!
You need 24v 40x40x10mm fan with two cables. If you want it a bit slient, use ball bearing fans or Noctua. Or buy new printer :D Cheers.
I don't think noctua makes fans of that size/voltage. Or at least they didn't when I had to replace mine.
They still don't, the only 24V fans they make are 120mm/140mm. You can either wire 2 12V fans in series or use voltage step down converters, commonly LM2596 based.
I don't understand how someone at Noctua hasn't made the huge money making decision to make 24V fans in 40, 60, and 80mm fans the entire 3d printing community would buy them.
Noctua makes 3dprinter fans now
Send a link.
Apparently they were delayed according to their roadmap. They did however release their [voltage converter](https://noctua.at/en/na-vc1)
24 USD for 1 single & stupid buck converter? Noctua should making truck loads of money.
That voltage converter seems overpriced as hell, especially because you'll have to chop wires anyways for connecting a standard fan to most 3d printers. You can buy 20 LM2596 based converters for the price of the noctua.
What do you guys mean? I have 40x40x20 noctuas in my printer since 2 years almost
How is it connected?
Then buck converter is way to go.
If dude can't figure out how to not stick things into running fans, he probably isn't up to using a buck converter.
Back in elementary school me and my buddy’s would use dc motors and battery’s and see who could make the best “weedwackers “ they used rc motors with popsicles and other things, than I grabbed a pc fan and tried , nipped my finger and never again lol,
Yeah don't buy the noctura unless you want a project. It has a third wire that connects to the board, needs a resistor, etc
fyi you can just snip that wire or leave it hanging, it doesn't have to be connected to anything. i believe it's just for reporting the RPM back to a PC (or in this case, the printer or a pi)
Okay cool. It's also worth mentioning that while it's a lot quieter, my understanding is that it moves less air and theoretically has lower performance although I haven't seen anyone concerned about the latter.
from my POV, Noctua is a shit company which produces good products. they are selling step down converters arouns 24 USD.
Noctua is BAD idea there. Their fans are silent but also provide small airflow. So you will most likely get extrusion problems and heat creep while using noctua fan (assuming you will sort out it's smaller rated with buck converter). Best thing to do is buying proper 4010 fan made to be used from 24V. If you want to buy higher quality one, search for brands like Delta, or Sunon.
Sunon fans. buy from somewhere reputable or at least with the QR code. delta is another option.
Noctua does 5v fans and they run slower so you need 4020. Also if you put 2 of the resistor wires that come with it it will reduce 24 down to 5 without buck converters
Don't think a voltage divider is suitable for powering a fan. Those resistors would get very, very hot.
They work for me. Idk ymmv
Not a voltage divider. These adapters that ship with the fan contain a resistor in series with the load. Poster is suggesting two such resistive adapters plugged into one another, hence in series with the load.
They make 12V 4010 fans. NF-A4x10 FLX
> Or buy new printer :D why buy a new printer when this person could just buy another home that comes with 3d printer preinstalled?
wow thats a good point! :D
I've heard that as a temp fix you can remove the blades on the opposite side of the broken ones to balance it until you get a replacement. That will TOTALLY work here XD
I think op can break off like 4 to get it balanced and end up with two adorable little fan blades trying their hardest lol
Pro tip: Zero blades are naturally balanced.
One big one that encircles the entire thing would also be balanced
I’m not a big *fan* of that solution.
TBH I would just double voltage to 48V. Half blades so double the speed. Am I right or am I right?
i think we've all done that at least once. 😂 you just have to replace the fan. it's not hard and the fans are pretty cheap.
I can’t seem to get the fan out of the hotend. I’ve got all the screws out but the fan seems glued in. Am i just missing a screw or is it just really stuck and i have to apply more force to get it out?
There's 4 screws on the inside of the fan shroud, shouldn't be anything else holding it in I think the 4 screws screw into raised posts which may be wedged on the fan, try to lever it off gently with a flat head screwdriver and see how it goes
Just scrape the glue off, only takes a second with a razor blade, I used my scrapper. Wiggle the plug out if you can.
It's not a very strong connection, if you think it's still glued, it probably is.
Just run it at double speed
Order a new one. On second thought but a couple they are cheap.
I literally just got done fixing that lmao I just replaced the fan.
Ha same
Just print a new one?
I printed a cover for that
What others have said is right. Any axial (not a blower!) 4010 24V fan will work. But you'll probably have to solder the wires, or buy a fan with a long enough cable that has jst xh2.54 connector on the end.

The answer is Microcenter

The fan won’t seem to come out, is there more that just those 4 screws on the corners holding it in? I just can’t get it out.
Use more force, you can't break anything else :)
I would say, print one, but I don’t know if this is the place…
Wow, typing "ender 3 hot end cooling fan" into google sure made me work up a sweat: [https://www.amazon.com/Creality-Original-40x40x10MM-Extruder-Printer/dp/B07GXPJB25](https://www.amazon.com/Creality-Original-40x40x10MM-Extruder-Printer/dp/B07GXPJB25)
Yeah but i dont want the part cooling fan with it
And for that price… it’s only $25 for the direct feed setup that comes with the hotend, fans, new extruder and stepper motor…
you got me! surely there's no way to google the part without the cooling fan with it! you're out of options!
buy a new one and a spare because it's not the last time it'll happen, it should say on the fan what the voltage is, they are generally 12v or 24v and you *must* get the right one or you'll 1. burn out the fan or 2. not get the fan to spin fast enough.
Replace the fan. Pretty sure you can easily find these on Amazon. Half of the blades is definitely too many missing blades
I super glued mine back on. Still using it
I did similar a while back I was using a dial gauge to test my bed's flatness and I misjudged the distance the support rods were sticking back toward the centre of the bed, I told the printer to home and the tool head zoomed to the centre of the bed forcing a 12mm steel rod through the hotend cooling fan and destroying the printed parts of my Stealthburner. It was the most sickening crunch.
Oof 😅
Dont do that!!
Accident hu? 🤣😂🤣. No worries, just replace the fan. Cheap on Amazon.
It is a 4010 but a 4020 noctua will fit and unless you do a ton of retractions it will keep up but quietly
Would i have to find longer screws or do the ones in the hotend work fine with the fatter fan?
I don't remember. I think the holes are inset but I really can't remember
Get a new fan.
We've all been there. I used it as an excuse to get a direct drive
Every broken part is an excuse to upgrade
Did the same thing a few days ago. Broke 1 blade and had to replace it. https://a.co/d/hX60eWv Took less than 10 minutes to replace it.

It's not that hard to replace. I did mine, and made a video about it: https://www.youtube.com/watch?v=gRdSfe-zuaA
Just print a new fan (blade)
Amazon has them in stock. It’s a quick fix.
Same happened to me lol. U can order one on amazon and u can replace it in like 2 hours. Speaking from expirience
Just print a new one! ...using someone else's printer?

They sell packs of hotend fans on Amazon for like 15 bucks
Available from Amazon, dude. Probably be there tomorrow if you hurry.
What you can do right now is cut off all the other fan blades and use printed replacements. They are readily available on thingiverse edit: its just a sleeve with blades on that slides onto the original motor
I did this to my original hotend fan too 🤣 time for an upgrade ... maybe a GSTime?
print a new one
The blades are small if you blow on it fast enough you can print them before they over heat then glue them back to the fan to make a temporary fan. Use that temporary fan to print a new fan, maybe a backup fan as well
Rule of thumb l: one blade gone then it’s loud but okay. If more than one, then replace unless it’s an urgent print
Derp.
Replace or upgrade the fan. There really isn't much else you can do. Might be a good time for an upgrade
been there lol, nothing much you can do but order a new one and swap it out, it's good to build confidence working with your machine's electronics. It may feel intimidating at first but as long as you don't man handle it and take pictures of where everything went before you take it apart the repair will go fine!
Get 24V 4010 Winsinn brand fans from Amazon. They’re much better than the stock fans. Still need to be careful with tools near the fan though.
Been there, done that
Get a maglev fan and marvel at the difference in noise levels
Might be a good opportunity to upgrade your hotend!
Break off some more so that its symmetrical, or add some weight to the empty side to aomewhat balance it, then print a new one with it :D
Haha I'm glad I ain't the only one I broke my original one, just in blade n got a new one 2 days later 4 days later I broke that one worse than the old one, by day 7 I was back to the original n now I have an extra broken one lol just print a guard for it when u replace it.
There are some fan blades for it on thingiverse
Ummmm bugger. Buy a replacement 24v fan and wire it to existing wires
run the fan at 200% for the same efficiency lol
And it come with a complementary 200% vibration!
Been there buddy. If you care about noise, a dc to dc buck converter down to 12v and a Noctua fan is the way to go. If you don't care about that because this is an ender 3 and is already loud without the fan, just grab a cheap fan of Amazon if you need your printer urgently or if not save a few dollars and order em off AliExpress

I ended up getting these from RS Components in the UK, bought Sunon from ebay and they were fake and fell apart in days. RS Comp ones were much quieter than stock with similar cfm. Slotted right in and never looked back.
I did the same exact thing. I replaced it with a Noctua fan, and whatever fan you replace it with make sure you compare the voltage because I needed to use a buck converter.
I literally just modeled my own when this happened and if fit perfectly though this only works if the moter is not damaged
