Ender 3 Silent Fan Upgrade (Upgraded Pro Vs Stock V2) 

Fanless yes!!!

this is one of the most violent modding videos i have ever seen. so much aluminum scissoring, i cried out in pain...

The difference is huge. Great video. 3 Noctuas are about $50 but you need to buy four so you can elevate the printer on the boxes :)

As a fairly experienced gaming computer builder, doubling up fans doesn't work as well as people would think, and the difference it makes is very very minor. The only time a 2 fan configuration works well is when you have a push fan on a cooling radiator with a pull fan the other end

Did you test airflow where you stacked up the fans? Generally that results in a loss of air flow of the more powerful fan from the resistance of the less powerful fan in its air stream. The less powerful fan doesn’t increase in airflow at all so it results in a net loss. Without a chamber in between the two like a PC case for example it’s regarded as a bad idea. This is why you never see it even in industrial applications unless very very specifically engineered as such…I can’t find an example of when it works well but I’m sure there is… CPS makes a reliable cheap airflow meter if you want to test it yourself.

Two fan in a series? That is hilarious! 😂 It will not give you a better performance than one fan. It make sense only if two fans spins in different directions(one clockwise and another counterclockwise) which isn't the case in your installation.

Wont the first fan force the original fan to spin and create a charge????

How to hack up your Ender 3 should be the name of this video.

E3V2 fan noise was ridiculous - and the heatsink fan was always active. One day I finally had enough. I took the cheaper route and replaced stock fans with generic 24V fans run at 12V. Added a PCB mod where the heatsink fan is only active above a threshold temperature. Feel better now - I hated all that noise lol. 🙉

Warning, noctua airflow may not be sufficient if you're running high temp, high speed or just a demanding hotend, so beware. However, you can use them for stuff like electronics, as they need less airflow and babysitting than your hotend.

wouldn't you want to unplug the other fan inside of the psu since the noctua will be blowing on that fan causing it to spin and could create a charge that could short out?

But a part cooling fan is still stock. It's not completely silent because biggest noise exactly from the part cooling fan and it is almost impossible to replace because there is a 24v controlled by pwm. You can install noctura fan there and limit fan speed in the slicer but guarantee that this will always work properly.

If you wore them with splitters won't the nozzle fan always be running ?

That’s cool I’ll probably do this later. After I get a few print under my belt

You just turn down the voltage on the buck convertor to slow the fan?

This has been a while ago but you ever figure out that you can print mods to fit all these fans on there

Great video and yes the Aquila from voxelab is wonderful I bought it as my first printer and have built it out from there way better starting point then my buddy with his ender 3 doing this upgrade now. Thanks for the tutorial lots of help keep it up!

Why aren't you measuring the noise with the Nozzle Fan On ? It's not an accurate reading without the nozzle fan on

The solution for the PSU is excellent and easy!

So is your hot end and cooling fan wired together? I’m trying to figure out if I could make my cooling fan work like stock where it turns on after the first few layers.

Turn the fan of the power supply around so it sucks out, the warm air (that already tries to go up anyway) will be sucked out and replaced with cool air from the bottom. This will improve cooling efficiency of the PSU. Also keep in mind that while cutting away metal improves airflow so that's a good thing, but it will also increase dust so be sure to blow out any buildup of dust (with can of compressed air) before it's sticking to your components and can't be removed with a compressed air can anymore.

the fan that you replaced the power supply works in the other direction, it takes air out from and not in to the power supply, you must turn it backwards... the part of the mother board... not good, now you must use boxes... bad idea.

ok im dont get it, you wanted to lower the decibel due to the stock fans, but you left all but one in there.

Great video. Just bout one for my first printer. Does having the upgraded part fan sucking instead makes of pushing make a difference?

The best question is why his motherboard is upside down

you have both fans running in series? why, you just make more noise and create less airflow. take out the old fan, in order to have multiple fans in series you would have to have a stator which has its blades pointed in the inverse direction of the spinning blades.

6:07 The airflow is upside down on the PSU (The PSU is upside down). The fan should suck cool air from below and release it out the top vent holes.

nice work man, i just ordered the Ender 3 V2, and why i was at it i also ordered the Dual Screw Rod Upgrade Kit, BL Touch Self Leveling Sensor kit, BIGTREETECH TFT35 E3 V3.0 Touch Screen, CR10 Heatsink Hotend Kit, Upgraded Aluminum Dual Gear Pulley Dual Drive Extruder Kit and the FYSETC heat bed gold springs. Cannot wait to get this bad boy all together.

Man that machine looks real messy now. I love the way you butchered the sheet metal work. Really professional! I laughed out loud several times when you used your huge cutters to leave dangerous sharp edges everywhere. I had to click LIKE as it was so entertaining to watch.

i am trying to do this but don't know where to find anything to lift the printer up do you have a link to the STL?

When the Fans cost 30% of the whole Printer.

To get around the 24v dilemma, without using buck converters, I would run two 12v fans in series.

I think my extruder fan is making the most noise, so I might get away with leaving the PSU alone. But I'm a complete noob here so I have a question. Do I need that chip you plugged into the PSU before hooking in the fan for the extruder fans as well?

youre gunna destroy that printer with that double fan setup

Best only fans video ever

I was thinking of an other solution, cooling the pcb with a teg.

I replaced the mainboard also with a 40x10mm nocta so u don’t habe a big Fan under Ur Printer and replacing the Print Part cooler i did that on my ender 3. 3x 40x10mm nocta That replaced the Stock Fan and u Fan Screew ist in and don’t need Hotglue 😅and 1x 120mm nocta fan for the Powersupply and of course the silent board. printer is now super quiet

Seems like Nacuta 40x15 doesn’t have enough air flow for the hotend.

sorry but i don't understand why did you put 2 fan on the hotend ?

Superb work! Thank you!

Are you not push staring the power Fan with the new Noctua? If so that would make small power and is not earthed making static? (if that fan kicks in shorting you hold board?)

You got a 235mm bed on it?

I did the nozzle and part-cooling fans but man this thing is still really loud. I put it by my PC hoping it wouldn' t bother me but it definitely bothers me. I have 2 more of these noctua 40x20 fans, anyone know if I can use these to replace the other ones like power supply and motherboard or w/e?

Well you could just buy a same size noctua fan, open the PSU, solder original PSU fan connexion and swap the fan for the noctua. The original is 12V & it''s not a good idea to add fan on top of each orther, this will damage both fan early and the air flow does not add (not at a point this is usefull/worth damaging the fans) In fact even if the noctua was less efficient, the PSU fan is controled with a temp sensor, so it may only goes on for a little longer and this avoid have this fan on all the time. Less noise and same effect, i don't understand why would you do it like the video, you use a buck converter that wasn't needed and this is more messy.

imagine spending so much on new fans and mounting them like this so their $ value for cooling is compromised xD. Unless both fans in line are spinning perfectly in unison then you're going to have some resistance and drag, which one, lowers cooling and two, makes noise! lol.

Not really an "upgrade". More like a design mod and not a very efficient one in my opinion. Was looking for a video on in place substitution of the stock fans with quiet Noctua model.

Man, thanks for this video. Very hands on! Especially liked the benchmarking before the changes. One Question: What gauge wire are you using between the power supply and the buck converter?

Great video! Has the production value of a much larger channel. It would be cool if you found a way to swap the part cooling fan too!

The V2 is a in general good machine I think but indeed I was a bit dissapointed that the PSU fan is so loud I need to use earplugs in my right ear to be able to sit next to the machine and continue working on the CAD computer at the left side of it while its operating without risking long term hearing damage as it is basically like having a hairdryer on full speed or similar constantly screaming in my right ear as I have set the V2 machine and CAD/Slicer computer together on a table as a complete workstation and while the machine is running one set of parts I meanwhile often like work on another set of parts on the CAD computer at same time while keeping a constant eye on the machine in case something go wrong, part comes loose from plate ect. Also the hotend fan is broken from start with cheap bad bearings that squeal and vibrate from start although I can get it to roll properly for an entire run by switching the machine on and off a couple of times and then the bearing will align properly.

How offten does the stock fan on the psu goes on?

Are you using a silent board for the motors?

I think this would only make sense if you have the motherboard with the silent drivers because those are honestly the loudest/ most annoying aspect of the printing process. If you do this to a standard mobo then you really are wasting time and money.

bro gained fans

How would you attach the second hot end fan onto the aquila?

is the upside down electronics case just on the ender 3 v2? the one on my ender 3 is upright

i can't hear the silence from your video because my ender is running :)))))

Do you know if stock motherboard fan is allways on or starting only when get hot?

So it is ok to run multiple fans on one buck converter?

he just cuts it out hahahahaha

your blower fan is not working

Absolutely blursed

Can you put a new fan on the side of the extruder

will you really build fanless 3d printer? wow! (12:15)

Gotta love a fan joke😄

noctua ftw

This can be a bad idea. People jump all over Noctua fans to make printers quieter, but stop to consider the consequences of doing so. These fans are quieter because the move less air. Less air means less effective cooling and on longer prints can lead to print issues and heat creep. Read up on it before you do any mods with slower fans.

Great Idea with Poor execution...

More fans for your fans….. why?

boo you had to show how to connect the wiring for the head fan, mate.. :((

Squashballfeets!! :D

noctuas are overpriced AF, i just bought 3x arctic cooling and 3 buck converters for 15 $

Seriously, you made this video just to make that joke.

I don't usually comment but you butchered that machine LOL

Oh my.. i mean yeah it could be just a tad quieter but its not as much the different fans its how they get air in, by removing any "gates" "small holes" ext from the fan inlet will make it quieter due to airflow.. but hey man if u feel that throwing out money on fans go ahead! I only recommend that one only print a new holder for the fans, as heat removal is a important thing... just saying :P

It kinda hurts watching you cut all of that metal lol

you are destroying your 3d printer, holy shit... You can basically print mods to make everything fit well, ya' know?

You monster

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rhecypP1-sg.html that's not how fans work XD

half of the printer price for new fans. This will be evolution. :-(

No. Just no.

This video is painful to watch

Самый рукожопый апгрейд, всё топорно, наотмашь, деньги есть - ума не надо.

So corny
