Best part of this video for me wasn't just a potentially useful shortlist of ducts to try out but getting to hear someone just freely call stuff "shithouse" and use phrases like "rough as guts" and "dunny paper". For an Aussie living in the USA it's always nice to just hear other Aussies be Aussies :)

Thanks for doing the research and sharing the results, Great work.

Thanks a lot. I really appreciate your work. With this video you have saved me many hours of research and spending money, to show enthusiasts to modify everything, that the engineers who design the machines are not stupid. The same goes for the Capricorn...which is another blef. Thank you sincerely.

The Satsana design ducts the air to the nozzle and the print directly below it, so if it was to blow the piece of paper then I would say it has failed at what it is designed to do, as that would be wasting the cooling by blowing it where it is not needed.

Thanks for this video. I didnt know about the fang duct and I can't wait for mine to finish printing.

I am very happy to finally have a video on this, thank you so much. most I had found only talk about the most Popular on Thingiverse and are kinda dated and not the most clear. side note, I apologies if you referenced this already as I may have missed it, but the cfm of the hotend fan is something important to note. RPM and the CFM are part of the reason Creality uses the fan it does. On top of that is the reason why swapping in *certain* Noctua or other random 24v fans could cause issues with a stock hotend. but I'm not versed enough on the scale of 30mm fans and the cooling capacities available and pricing in bulk. but price and commonality might be another factor why creality sticks to the same basic 24v fan. among other reasons and speculations I'm just happy to finally have a good video on cooler designs, you are a god send thank you.

Just bought the briss!! Awesome video!! Been looking for a video like this for days

Thank-you for this, that with understanding fan options on the Ender 3 v2.

I greatly enjoy seeing all the people's different opinions and beliefs based on different products because of this we have great products to use in 3d printing

thanks a lot for your comparison and troubleshooting on the 2 fan models, i recently changed my ender 3v2 to a dual 4010 side fans and a 20x40 front fan and started having the same termal shootdown, now to prototype again or just never use too much fan since is better and more silent than the stock one

27:10 without a doubt the design of the VORON Fan Duct Ender 3 V2 is the best very beautiful.

Thanks for great video and research , I printing 4.3 right now!

I've been using Briss fang V4 for 1.5 year now and I really like it. The only problem is that I print a lot with higher temperatures (240-260C) and even when printed the fang in ASA the tips of air nozzles are still getting a bit melted over time. Also, I'm using the version with LEDs for hotend lit and they don't last too long (couple of months at most), likely due to high temperature (even though I'm running them at a small current of below 10mA). Right now I have a V5 printed out in CF Nylon, this one should be much more heat resistant, so I hope the air nozzles will not be melting. Also - you need to remember to glue-in this extra piece for these (I see it's not present on your prints). It's not relevant for cooling test like the one you're doing here, but if you install them without this piece it can cause some problems with clogging (you will loose some cooling of the hot end heatsink and will have some unwanted cooling of the heat block).

Thanks, I was looking at E3v2 options and found the $2 BRISS and liked the look of it - then I found your video, you have convinced me to try it. Your 'dunny roll' test is much the same as the bowl of water test that others mention except turned through 90 degrees. Maybe if you ever repeat the tests you could find a source of smoke or vapour so we can see what is going on, I suspect that some of the designs are just cancelling out the the opportunity to move air away by blowing directly at each other from both sides. I wonder what a BRISS design would be like with an adapter on top to utilise two blower fans? Anyway thanks again, interesting video.

i only can say, thanks you mate, amazing work

I think the small bowl of water is a better test right under the nozzle on the bed where it would be printing. You can see where the air is focused. It seems you have printed a fair share of the designs out there. The Hero Me Gen5-7 work really well with a dual 5015 blower style at 50% or less power. The purpose of 2 is so you can have less noise and get great results.

Thank you for putting in the leg work

This is the only video I've seen testing fans against each other directly! Thank you :)

Thanks for the video, learned few things.

Thank you for the video. I bought the Briss fang files, but I'm not sure if they will be compatible with the Ender 5 Plus with the BlTouch and which one of those files? Also, should this be printed with or without supports? I'm concerned about getting the supports out of the ducts. Thanks

Thanks for the detailed video! It saves a lot of our time to try them all out. I really like how simple is the "Headlock__Dual_FanductV2", wondering if you can upload your modified version of it?

I went with the satsana on my E3V2 but with dual 5015 part cooling fans and a 4020 hotend fan and its pushing at just 40% and quiet as a mouse 🤙

The part cooling fans should be of the high pressure variety, which have broad flatter blades than the high velocity fans. I use them for electronic system radiators which the fins slow down the airflow and don't perform as well as with standard fans.

thanks for sharing , I just the beginner of FDM print by Ender 3v2, I found most user would upgrade the cooling duct, yr video was awesome reference to me for the coming upgrade, BTW, the original fans could be use on the briss fang free version?

I ordered some 3010s. I printed that Headlock you liked. I was disappointed that it looks like it is for E3D not a creality hotend. Did you mod it for the Ender? I have an Ender 3 v1. Are the mounting holes that much different than the V2? Maybe you can do a vid how you'd put LEDs on the cooler mount. As you mentioned. I need to be able to see if it is printing okay, so those giant ducts are not for me. Thanks.

Muy bueno y didáctico tu vídeo !!! Se agradece el compartirlo, saludos desde Córdoba Argentina !!!!

Increasing air flow will improve PLA printing results or upgrading the fans is for other materials and lower sound?

Hi I am wondering what is your ambient temperature where you are while you print? And what type of fan did you have ontop of the birds fang?

I had the same issue with thermal runaway it was driving me nuts and it only happened a few times at first then i had a 25 hour print due to power failure and then it was an issue about 1 hour into any print

Thanks for the video ;) What would you recommend for the Bondtech DDX + Mosquito combo on an Ender V2 ?

for the Headlock_Dual_Fan (with the BIQU 30mm fan in the front) which ones did you use on both sides?

Nice video , It's hard to see how these mount to the Ender 3 , There's not many mounting hole on the Ender carriage , Do you need to drill more holes. ?

Give the Hydra a shot. With dual 5015’s you can turn them way down and get an immense amount of air. It puts the briss, and all of the others, to shame.

You just got yourself a sub with one phrase, “will make your prints looks like shit” I like brutally honest!

I would love the files for the small voron style fan duck. Would you mind sharing it?

Would you mind sharing file(s) for the shroud at 24:05?

Is that a stock fan on the top of the Voron? I just printed this for my Ender 3 pro. What size hardware did you use to assemble it?? Great t!

I am using the voron and have had great success with all prints

Hey man thanks for the video I know this is from a long time ago but would you be willing to share your remix of the Headlock shroud that would be suited for the Ender3v2

Where can I find the compact one that uses 30mm fan?? That looks right up my alley!

I watched your video, thanks. on the 19th minute you show the insert after the cooler, can you share it with a 3D model? Thanks.

Great video!

What are the fans being used? Have a source or description? I keep getting results that look more like mini whistle shaped.

Great video, do you a link for the fang fan duct one piece including cr/touch mouting Thanks

What is the name of the cooler at 15:50? Seems like that was a solid option for my new Ender 3 V2

Don’t expect any answer but what fans did you use for the cover that is hinged I am looking to make it but I want quite fans

what color is the Voron fan duct and the other similar ducts ?!? Been looking for it all day!

I am not backing up the Satsana in any means at all but I’ve been using one for 2 months now and they have a focal point that your setup can’t really show, a smoke test would be better in my option. Your set up with the Satsana is showing all air blowing out from underneath the part which is why you have to shove the ducts into the little paper strip, the focal point is at the nozzle and no other airflow is really wondering away from the nozzle.

Have you tried the King Orca? It gives me some great results

Hi did you ever found the party that attaches to carriage on ender 3v2 for the Headlock__Dual_FanductV2? If so can you please share? Thank you

Link to a Creality duct that can be printed? And links for the rest of the ducts (maybe not Satsana ;) ) please?

Mate, awesome video TYVM... I have printed BRISS fang's latest It came out great. Just wondering what fans you would recommend? I am after something pretty quiet if possible and preferably 24v. Thanks again!

Thank you.

Thanks for the video :)

I didn't even consider changing my stock ducked out until I printed ABS and melted the crap out of the duct. Not exactly sure what happened.

cool. but where the file for direct air flow for cold end? ( ender 7 fan style ) any link?

great and informative video! thanks! Now please the same for CR-6 SE :D I need a solution which is better than the already good stock cooling fan :/

In my experience the payed briss was by far the best too. But I'm going to switch to a direct drive setup and now I'm not sure which one to choose.

great video really good what fans do you recommend

I'm printing an Hero Me Gen 5 right now because it seemed by far the most popular right now. One other reason is that I would like to try the double 5015 blower setup at low speed to possibly reduce noise. Do you think it's worth it?

Them 1st to Ducts don't work well as there is a very poor seal around the duct and air comes back up I still feel the bullseye is a great choice

i printed the fan ( 24 min , headlock dual fan ) but the file is different than the one you showing and wil not fit on the ender 3 pro ! where can i find your file from this little cooler 🤔

Any link for the last one maybe? The Dominique one please.

what layer fan do you recommend on an ender 3 v2 with an e3d v6 hotend?

the new stealthburner is a day and night difference to the old afterburner, just letting you know :D

mini Satsana is my way to go!

How does a single 5015 petsfang fit on the list? I use it and works very well, good upgrade over stock.

Hi, can you share the STL for the air restrictor you've shown on your video for the Ender 7 style fan duct? I need that part, thank you!

Nice video brother...what would you recommend for ender 3

Do you have the link for the fan you recommend? Good informative video!

do u finish that duck/fang? can u share with comunity?can u give the link?

Do you have link for Dominic design or the very compact one I would like to check them out. Great video I like the comparison demonstration of each duct. I have the bullseye now and want something that performs and looks good. Thank you

What kind of fans are you using I am looking to upgrade

Printed the ender 7 style cooler. It is not compatible with any ender 3. Only the v2 guess how i know. Made it work but the cooler is so low that it crashes into the bed clips. Loved the design and idea but just doesnt work in my case. Im surprised there was no remix made to fit those printers

I think you are overhyping the Briss fang. I currently use it and it has worst cooling on overhangs than the stock cooler. The axial fans are no match for the blower stlye fans once the ducts are close to the bed where the static pressure is increased. i improved the fang by printing little flaps that redirects the air more towards the nozzle which improved cooling and overhangs.

Would liked to see the Blokhead tested as well.

I doubt the test setup a little bit. It's not about how much air is going down but more how much air is going to the tip of the nozzle which includes also air going "sideways" instead of just down. In you setup this would not be recognized.

does it work on ender 3 v1? I'm Brazilian I don't understand English very well on the video

Thank you for the great video. Could you send me the files for the Print at minute 24:02 . The one you uploaded on thinkiverse looks different with two holes on the top. And also: Could you recommend the fans you would use with it? The Briss cooler looks not as nice, but still seems to be your favorite? :) Have a nice day, regards!

satsana duct with 5015 fan single or dual works real good not the 4010

so which one best with stock fans ?

Have you not tried out hydra or hero me?

Hi can I print those out of PLA or do I need abs? The heat scares me a bit

Non of the links you mentioned are in the notes. Where do I go to get the final design

Can you share a download link for the "AYF" ones at 19:55?

Have you tried Petsfang V2?

just wondering why you didn't include test with 5015 ?

Can you send the file for air funnel of Ender-7 style fan duct?

I’ve never understood why people who design these things so often feel the need to redesign the entire hotend area and not just make some ducts that attach to the fan mount, or just more simplistic and direct stuff. Most of the time all it’s doing is adding weight and size for no good reason. Doesn’t even look good.

Whats the best for ender 3 v2 with stock fans?

Very useful

Will any of these work for ender 3 pro?

try bullseye blockhead fan duct 5015

If only the Briss Moto had bltouch for the voxelab aquila man I would use that.

I have just printed my own design, weeks in the making! I can send it later if you want?

Wow man just watched it all, glad i did, I printed one of the shit versions of the fang. Looks like I’ll need to get the good one. I am kinda keen on a quiet setup, i like that other compact one with dual blowers. Wish it had a 40mm hot end fan design

Hi, dod you find the desing from min 24:00=?

? For you. I just got briss for my Ender3v2 running stock fans. I can't print more then ten mins.. I replaced thermistor and did a pid tuning. Nothing seems to help. Thinking due to stock fans

Can this be used on a Ender2 Pro?

please add links to the mounts you used in the video description
