Blowers are useful when operating into a higher pressure, like a part cooling nozzle. Thanks for the interesting video.
Great point! Thanks!
Check this excellent video for that: czcams.com/video/SX-okOHvh1Q/video.html
Therefore the test in this video doesn't say much about part cooling. You need to test ducts for that.
Static pressure is a key characteristic for both hotend and part cooling fans due to their usage blowing through ducts (part fan) and through heat sinks (hotend). High static pressure is more important than high cfm flow
@@ChrisRiley lol knew it would be the Alex Kennis video.
@@Sebazzz1991 yayyy Alex saving the masses!
Hello Chris,
I am HVAC Engineer
Nice test but absolutely not relevant for the blowers
Blower are designed for high static pressure, axial fans are absolutely not designed for static pressure. The measured airflow index (Speed) is probably wrong because your blowing on the center of the anemometer without a diffuser ideally you should measure the air intake of the fan or use a diffuser on the supply of the fan. If you want, I can design something
Greetings from Belgium
It is relevant since it's a comparison between several identical fan styles, blower fans which output higher wind speeds will have higher static pressure.
I worked for Lennox building blower fans, from 3 ton up to 30 ton units.
No because the reading are wrong depending on the speed and turbulence created against the anemometer, trust me if you want a clear reading measure the air intake
Thanks for the tips, I knew something wasn't right. I for sure want to setup another rig for more testing.
I was just about to hit the purchase button for a bunch of fans! Perfect timing! :) Love your vids, keep up the good work! My number 1 source for 3d printer knowledge.
Awesome! Thank you!
Incredibly useful! Thank you Chris for your time well spent, great put together!
Glad you enjoyed it!
Great subject matter, Chris! I love videos like this. Thanks for taking the time!
Glad you enjoyed it!
This is an enormous amount of work , thank you!
Thanks!
Fan tastic job Chris. Thank you for sharing the test results with us.
Woo! Thank you
That's pretty good work with a decent overview on the noise/output differences between various brands and voltages. And makes for an excellent follow-up video with knowledge imparted in the comments. Test all the fans Chris!!!
Glad you liked it!
wow... awesome.. very useful and consistent... we appreciate your effort for making this video, thanks!
Glad it was helpful! Thank you
Really useful video, ther int enough of this back to back real world testing done. Awesome work !!
Glad you liked it!
Great Video Chris! Love the info and time put into this!
Thanks Jim!
Chris, I can tell you devoted a lot of time and effort to this. I would like to see a review on the different fans used for part cooling. 40x10, 40x20 etc. I think most people are concerned about that since there are so many designs for that application
Thanks for the idea Dave!
much needed video, thanks for sharing!
Thanks for watching!
You are making me think about replacing my Noctua with a Sunon on my MK3S... Nice!
Hey Dan, I have seen a lot of other folks be really happy with that swap out.
I have also been buying a lot of fans to fine the best ones, thanks for making this video!
Happy to help! Thanks
Extremely helpful thanks for your effort
Thanks, this was a fun experiment
Wow!Amazing job, very useful information!
Thank you!
Thanks for the test!
Thanks for watching!
Excellent work and very useful information.
So nice of you, thanks!
That's awesome, I did a similar test myself with a anemometer comparing the stock 5v fans on my Lulzbots to Noctua 40mm fans. The Noctua fans output roughly 10% higher "wind speed" than the Pelonis fans. I have always bought Noctua fans without doing much research as I thought they were industry leading on the noise to output charts, now I know better!
Thanks! Yeah, I had a lot of questions as well. Not sure if I answered them, or just made more. LOL
That was very interesting.
It kind of proved what always thought. The Noctua fans are quieter because they spin slower and move less air.
Great job!
Thanks!
Something to keep in mind - airflow fans and pressure fans are fundamentally different. The typical 5015 nozzle part cooling fans are pressure fans, they aren't supposed to deliver a lot of airflow. On the other hand, axial fans are typically open enough that they don't have a way to counter backpressure, the air can slip right through them backwards.
What happens when you drive an axial fan into a narrow funnel such as a part cooling nozzle, the airflow pretty much blocks up by vortices and backpressure, and they simply don't make enough static pressure to push through. You might get some air movement just a little bit on top speed, but not much. With centrifugal/radial fans, a lot more useful airflow remains.
So maybe running the fans through a narrow constriction and then measuring the airflow could make for a valuable test?
Also it can maybe be good to have measurements of each fan at different voltages, then you can fit a curve to each and compare them, maybe some fans will jump out as being particularly interesting. Though i guess apart from firmware PWM control, most people unlike me won't be willing to vary fan speed; me i have drawers full of adjustable regulators, so i don't mind.
My 5015 fan that i got from an anonymous seller over 3 years ago is showing severe wear, it's still properly lubricated, but it has gained some bushing wear or maybe it's cracked, anyway it's now prone to vibration and extra noise. I have now ordered a Sunon MagLev MF5015VX as a replacement, it should be in the mail shortly... but i wonder whether i should have gotten a Delta or something instead.
Thanks for all the great info here in the comment.
Now this is an awesome video. Just one itsy bitsy enormous complaint. Lol. Music over the tests? db is only part of sound. That's where opinions differ greatly, not db but the actual sound. Something that runs 46 db may be more annoying or seem louder than one at 55db because of frequencies, vibrations, squealing, etc, it produces. That's why sound is so relative to those who hear it. I would seriously love to see this video reuploaded without the music over the tests. And if possible, each test labeled with the fan info, model, voltage, size, etc. We can see a lot of info by the image of the fans you added but some things are difficult to read. But hey, this is a badass video dude. I'd love to see even more fans compared. Part 2 perhaps? đ Keep it up dude. Much respect.. ~DCT
Thanks for the comment. That was a tough call, I thought it was a little boring without the music. I did post it without the music for my Patreon supporters. czcams.com/video/5h4VztHoeEE/video.html
Thank you for sharing the link without music. Definitely helped my decision by being able to hear the nuances of each fan.
I dare anyone to not break out dancing while watching this video... impossible! Excellent work Chris!
Thank you!
Very interesting! Lots of effort for this video for sure and greatly appreciated. I wonder how the numbers would look like for higher pressure applications, like the air having to exit through a narrower space like we have with the extruders. They say the blowers would win here.
Good question! Thanks!
Thanks for doing the thing!
Our pleasure!
Bro, thank you for your effort and time, nice video!
Glad you liked it! Thank you
This is an excellent roundup, but one thing I'm missing is any way to compare static pressure.
Especially in high restriction scenarios, like parts cooling and restrictive heatsinks, that would make a big difference for fan choice.
But I don't know if you have the equipment to do that.
Still, this is a great and pretty comprehensive comparison.
The dirty way to measure static pressure when having fans go head to head is message a delection of a pivoting object. You won't get hard numbers but you get a way to compare fans against each other.
I for sure want to come up with another round of tests.
@@ChrisRiley Any interest in doing a slew of industrial fans? More Sunon, Delta, TDK/Lambda, Orion, etc..? I'd love to see how some of the cheaper industrial style fans compare to the ridiculousness of Noctua. I run a mix of Orion, Sunon, and Delta on all my printers and would argue its been one of my most rewarding upgrades.
I think there are 2 things you didn't take into account that make a lot of difference.
The first is static pressure, which is where the blower fans will win. To make it a fair a fairer comparison make a smaller blower outlet (similar size to the blower output) and test the fans again.
The second (which is very hard to test) is the type of bearings used. Some bearings will be very quiet initially but quickly become very noisy after a little use. So even though very cheap fans might perform great now, odds are that they won't stay that way for long.
In any case, very nice and useful comparison. Thank you!
Thank you for your insight!
Very nice test đđ
Thanks đ
Chris, great as usual man! There's some folks within Voron Design group, working on cooling/ducting ideas, and their data mostly matches to what you found... Sunon are great for 3010/4010 axial, and, even tho you won't find them on OEM printers much, the Delta 24v 5015 is pricey, but is the best radial blower out there.
Thanks!
You wouldn't happend to have a link to the blogpost or video? Or is this from their Discord or the like?
Thank you! This is a valuable resource for the whole community! This is the nerd version of project farm... "nerd basement" would be a great new segment.
Nerd Basement, I like it! Thanks
THIS IS THE BEST VIDEO OF THE YEAR.... chapeau !!
Wow! thanks
Wow thank you so much Chris. I knew that the Sunon are really good. I had better results with them. Everyone hypes Noctua but they don't have the same power... Amazing video and really cool data!
My pleasure! Thanks for watching
Fantastic.
Glad you think so!
Very useful with heatsink cooling for the standard fans. Hard to test them blower fans as we use those for pressure, in part cooling like you said.
Yep, thank you!
Excellent thnaks for the exaustive video !!!
Ooo, good word! đ Thanks for watching!
very useful!
Glad it was helpful!
This is really cool. I wonder how a Mechatronics fan would do? Or the TH3D blower?
I agree with the mechatronics blower. It's quite loud but I wonder if it will stand out in the airflow department.
Good question, thanks!
I've been purchasing fans lately and my choice is sunon for 5015 blower, 60x10, and 40x10 but I also needed 3010 blowers but sunon doesn't make that size, I went with winsinn unfortunately since they were easily sourced and indeed they are not quite.
I chose ball bearing for longevity, keep in mind ball bearing fans usually quite down after around 20 hours of use but aren't generally as quite as hydraulic or sleeve bearings.
Nice video and I'm glad to see sunon get the recognition they deserve.
Thanks for your insight and thanks for watching!
Makes good sense that they quiet down after running the bearings in for a bit and they loosen up
Love this kind of research, could add in the difference between a cfm and static pressure fan , this is useful to decide witch fan to use for what application.
to cool a pc/ electronic/ chamber case its recommended to use a high cfm fan,
to cool a radiator/ heatsink/using ducts its recommended to use a high static pressure fan.
Good idea!
Nice work.
Thanks!
Great workout pace! đ€Ș
Thank you!! đ
Might be it would show better differences if the tube where shorter in the blower fan test, great content Chris :)
Great point!
Would love to see a partcooling fan test
đđ
To quieten my Ender 5+ down I put in a fan less power supply, the cooling fan for the control box I put a really big fan in then controlled it with an Arduino and a temperature sensor, the warmer it gets inside the box the faster the fan goes works great, most of my noise now comes from the hot end cooling fan and even that is set up to be off below 50 deg as per your video :)
Cool! Thanks for watching
Big fan, of this small fan, test!
Ha Ha!
The difference in axial vs radial/blower is the latter will make flow at a greater path restriction than the former. The part cooling duct plenum will pressurize to increase velocity at the outlet. While Axial fans may move more air in open space, they will choke when coupled to a part cooling duct.
Thanks!
Great video! On the blower or turbo fan, I heat glued over where the cables that go into the engine. Under the cables, itÂŽs usually open in the plastic into the fan wheel. Which makes the air come out and noise goes up. May be my imagination but it feels like it works better and sounds less with that hole glued shut. Be careful not to get glue on the fan wheel. It would be nice if you could try it and give an update if there is any difference.
Interesting, thank you.
The only fan i missed here was the 5015 blower sunon maglev one :D Anyway an AWESOME vid!
Thank you!
Purchased these, generally they run great at acceptable noise level but I dont get them working with lower PWM rates. Swapped today to GDS time and they work fine at lower rates. Generally PWM would have been great as another aspect for this test
@@tobiasinglin5644 Mhm, here's the added function key for the models that i found:
999: standard model
A99: AutoRestart
C99: F type (3rd wire)
D99: with PWM
F99: AutoRestart and R type(3rd wire)
G99: AutoRestart and F type(3rd wire)
H99: AutoRestart and with PWM
Q99: AutoRestart , R type and with PWM
S99: AutoRestart , F type and with PWM
Apparently AutoRestart can be the issue. It detects what it believes to be rotation stall and then disables the fan for like 5 seconds.I ordered one and it turns out it has G99 function, but i suspect i might receive A99 instead, weird seller. Odds are, i can make it work, either by prepending an RC or LC filter or just by playing around with PWM frequencies, higher or lower. Or maybe i should cancel the order and get a Delta? I'm not up to buying junk fans again, this one has taken mere few couple hundred hours tops to start failing.
Great! Thanks! Maybe you could do a review of hot end heater cartridges next, PLEASE!
I see what I can do.
It would be interesting to see if the green Sunon could match the Noctua's numbers if undervolted.
That was mentioned a few times, I might have to see what happens.
I'm looking for a quiet blower fan, so thanks for the Google Sheets table!
You're welcome! Thanks for watching
Thank you for your effort Chris. This video was very helpful. It would be better without or very low music for fan sounds though.
Thanks
Fantastic information for the makers. If you included the weights of the fans, it could help people building faster printers :D
That's a great idea!
Awesome Video Chris, really great information. I'm going to be looking for some new fans for both my Ender 3 Pro V2 and my Mingda Rock 3 Pro. I don't suppose you have a link or STL for a part cooling duct that would work well on the Mingda Rock 3 Pro? I haven't been able to find anything.
Thanks! I don't but I will take a look around, there isn't a lot out there for the ROCK 3 yet.
Thanks for that Chris
You bet, thanks for watching!
Very cool test. I did a "low tech" version screwing fans to a box with 2 holes in it, the fan in 1 hole, and a piece of paper over the other, and saw how far the paper blew out
That's cool. How'd it go?
@@ChrisRiley I didn't have nearly the amount of fans as you, I was comparing noise and flow between the stock creality hotend, winsinn, sunion, and a no name, just making sure they didn't have less flow than the stock fan. One thing I did learn, most winsinn 24v fans are just 12v fans with a 24v sticker spinning way too fast.
@@B3DPrinting đ
@@ChrisRiley yeah, after testing them, I'm definitely not a fan, ha ha. I got my skr e3 rrf in and set up, the esp8266 lasted about 6 hours before it let out the magic smoke. I wasnt very impressed with the performance with rrf firmware, but didnt have much time to play with it. There isnt a lot of support or info, I was having issues getting the bl touch to work, and z offset set. I'll have a new board tomorrow. Another question, the skr e3 rrf in Marlin mode, is there enough serial ports for the tft35 v3, wifi, and usb?
Legend!
Ha! Thanks!
Some experience I just encountered, I put a biqu h2 on, and I had a chance to use either an axial and a radial fan on the same duct. Where there was resistance, the axial fan didn't push the air through the duct, it cavitated, and pushed the air back on the wrong side of the blades. If you do another test, maybe make some type of venturi, to test the fans pressure ability. Either way, great data, thanks!
Cool, Thanks!
Great video
Glad you enjoyed it, thank you!
Good video!
Thanks!
Chris -- I admire the amount of work you put in, but I think you only got part way to a satisfying result. The fans need to be blowing into a load (constriction) representative of their intended application. Fans produce some max flow rate into a low resistance (fan with no load), but progressively less flow rate as resistance increases (constriction) and hence also pressure increases. You measured essentially the max flow rate into low resistance, but did not explore the flow-rate versus pressure, or flow-rate versus resistance curves, which would be highly interesting, among other things demonstrating the contrasting merits of the axial vs radial fans. I could imagine revising your rig with an adjustable aperture downstream from the fan, as a start. And a pressure sensor would be informative too, along with monitoring the electrical current (and hence power), as an alternative assessment of the load. The flow rate measurement should be upstream from the fan, to avoid turbulence interacting with or caused by the geometry of the anemometer, though I'm not sure that's a major factor.
Thank you for your constructive criticism.
Great video, I am a fan of it..... Ok, so maybe my joke blew too hard, but seriously amazing video!
Ha ha, thanks!
I noticed the sunon maglev reds vibrate alot, I had some on equip at work and had to replace them all ( maybe they were counterfeit.. )
Huh, that's interesting.
You need to start a fan club. ;)
đđ
First rule of fan club.....
@@reasonsvoice8554 First rule of fan club = have a fan-tastic time :)
@@TootEmCarMan nah
Dont blow on about it
đ
What I always wanted to test is...
Noctua VS sunon, but adjust the voltage down on the sunon until it is the same volume, then see which pushes the more air.
If you still have your rig setup I would love it if you could post he result in the comments.
thanks for the great video.. đ
A couple of people have said that, now I need to go test it. :)
@@ChrisRiley and that's why we love you.
I'd like to see a longevity test. The stock fans in my Ender 3 seem to start squealing and making a horrendous noise at around 200-300hrs of printing and need replacing. I've even had a couple fail after only 50 hours.
I'll look into it!
I really wish there were silent blower fans. I guess that's mechanically impossible, but it would certainly be nice.
In a perfect world...
I think something you might be looking for, might not be a fan. But a piezo aquarium air pump. I feel this might work for part cooling, if you run it through a very narrow air nozzle there directly on the hot bead as it exists the nozzle.
I haven't tested this idea, but i thought i'd share regardless. I actually had this thought several years ago but then instantly forgot to follow up on it.
The blower type fans, aka centrifugal fans, are designed to push air with brute force. They create high pressure which pushes the air out forcefully. This is advantageous for cases when the airflow path is not straight, thus you see it used in part cooling where the airflow is redirected through a duct. An axial fan may not create enough pressure to overcome the drag inside the duct, and thus reduced airflow for part cooling.
Moreover, from my own experimentation, I found that cheaper fans produce a lot of tangential flow, which just circulates the air in a rotational motion instead of a linear axial flow which we want. This could easily be fixed by using a fan duct that straigtens the airflow, but then it adds extra parasitic drag and may interfere with the acoustics. My noctuas however produce airflow that is very straight right out of the box. I don't imagine this to be easy to test, but I presume that noctuas may perform better even though they deliver less airflow or static pressure.
Thanks for your insight!
Greate video
Thanks!
Pro tip: When I want to calculate CFM I go to the manufacturer's spec sheet and I read the value from the "CFM" column. đđ
(but I get it, that wouldn't make for a fun video)
Thanks for the tip! đ
The dB is on a logarithmic scale - +3 dB essentially doubles the intensity of the sound. On that basis are the Sunon dans still better than the Noctuas in terms of noise per flow rate? Also have you considered static pressure vs. Flow rate for axial vs blowers? Perhaps different requirements for both designs?
You've given me something to think about, thanks!
Had the same thing in mind when I was watching the video. Would be interesting to see, which flow the sunon would have at 40dB.
The blowers donât compare because they have high static pressure. They flow much higher rates than the axial flans when the air is forced through a constricted duct or vent.
I hope to get another test going for these.
Your duct and mount prints look really clean. Cant tell if it's just the video though. Anyways, next time it would be interesting to see this done in categories/different videos of like 40mm fans with a comparison chart at end then 40mm blower fans with comparison chart and maybe a shootout with bridging, short layer times ect all tested along with different fan configurations like 1, 2 or 3 part cooling fans in different layouts. I've had great success with 3 5015s in a 120 degree layout in the past but finding good 5015s is difficult so I have resorted to over volting 5v to 8-10v changing them out regularly as a result, plus they are cheap quality to begin with. This is a great subject IMO that hasn't been covered properly in the past.
Thanks for your insight!
Wish I could get a better fan for the Prusa Mini the hotted fan is noisy. Prusa use a Delta fan at 5v, people have tried to use Noctua but they don't work properly
Hopefully they will find an upgrade for it.
Thank you. I bought creality k1 - very noisy printer. The same, I prefer sunon fans.
Thanks!
Good
Thank you
The db readings are good to see and while we get some notion about airflow from m/s. unfortunately comparing blowers to inline blades is apples to oranges. blowers can compress air slightly, this is incredibly important where airflow is constrained. in fact open blade designs are really only meant to move air in space that cannot pressurize from airflow. I would like to see you do this test for airflow where the tube is actually slightly smaller than the fan output. it is almost certain the blower fans will handle it with near indifference while the inline blades will suffer huge performance losses.
It was a shot in the dark pretty much. I hope to create a better test for the blowers.
@@ChrisRiley thanks for the hard work man! I'll be on the lookout for it if you make one.
very useful to me who has been looking for better fans i went with winsinn fans and are horrible and i am looking for a well built solid fan that works i would rather buy a great quality fan that i don't have to replace often maybe clean regularly but lasts for the test of time a nice german made fan would be ideal in my opinion.
Thanks for watching. Good luck with your projects!
Could you please upload another video just of the fans blowing and in the same format as the testing part of the video. But without the music, just so we can heard an audible and comparable difference in the fans.
Another piece of advice to help, from the perspective of a viewer is organizing which order you show the fans, either by size of mount, type, or voltage. I think voltage and size of mount would be two of the most important details to have on screen outside of the speed and decibel measurements that were taken.
It helps significantly to help a viewer organize and understand which fans are the most similar and compare them. Since pinning a 5v fan against a 24v fan can make a massive difference in sound and how much air it moves.
I was thinking about uploading the non-music version for my Patreons, organizing them was a thing a struggled with, there were so many different configs.
im a big fan of this guy
Zing!!!!
Is there a way to check if the fan is compatible with 3D Printer? I bought a Sunon MF50152VX-C02U-A99 -24V 2.86W but it's not working at all when hooked up to the mobo but runs when connected to 24V PSU.
The should all be pretty common, just make sure the wiring isn't flipped. If you PSU say 24v then it should work. If it's the part fan you might have to turn it on in the menu.
Have you considered the aerodynamics inside the duct? A small fan will suffer from turbulence inside the duct and will not be accurate as the duct is a closed system. Or am I wrong?
I really have no clue, I need to revisit this how all this works.
I think the blower fans are designed for lower flow higher pressure
Thanks for your insight!
Can you make a video about part cooling inside a heated enclosure? I think BerdAir might be the best way to do this, but I'd like to have your opinion on this. My goal would be to do nice bridging inside an enclosure without compromising the temperature of the rest of the part much to reduce warping as much as possible.
That's a really interesting thought. I am getting ready to do a big enclosure series. I will look into this.
@@ChrisRiley Nice, looking forward to it!
@Chris Riley - What would you recommend to replace the god awful Hemera heatsink fan? I don't want to throw a noctua on it because I'm pretty sure it won't cool enough. Thanks for the great video.
I would go with the Sunon .72w.
@@ChrisRiley I had my eyes on this one: Sunon MF40102V2-A99. 1.11W so do you think it'll be louder than the .72W? Also I posted a video on my channel about the Hemera Fan at different voltages, and then put on the stock ender 3 heatsink fan. Just need to test to see if it pushes enough air to cool. If you could watch it and leave a comment that'd be dope.
Darn, I was hoping to see Noctua 40x20 and 40x10 @ 12v
Very cool video though, really like this format.
Thanks!
The 12v versions have the same specs as the 5v version. They should perform the same given that they are run at their respective rated voltage
Nicholas Lau so they are, good heads up! 40x20 would still be neat to see, but I suppose we could infer their performance based on Noctuaâs posted statistics
How did the 25mm 24V Slice Engineering perform?
I didn't have one available of this one, I will add it to the list.
Thing to note about dB is that 3dB represents a doubling or halving of the perceived loudness.
đ
It does not. PERCEIVED loudness is linear in dB-scale! At least this is the case around midrange, further out this is not entirely the case, due to Fletcher-Munson curves. But for dB values which don't differ by more than about 20-30dB, you might as well consider them perceptually linear.
Putting two identical sources of noise right on top of each other will indeed increase the measured SPL by 3dB. However it doesn't make it twice as loud. Indeed if you had two identical fans near each other, each being about 50db loud, or 53db total, and you turned one of them off, the noise you're hearing would be slightly less loud, not half as loud. However, due to your experience, you would also know that you're hearing one fan as opposed to two, so you would know that this fairly moderate difference in noise volume corresponds to half as much or twice as much noise power. Confusing, right?
It's also the same with light. Two identical lightbulbs aren't twice as bright as one, they're moderately more bright.
@@SianaGearz thanks for the correction. Been a few since I was into dB (car stereo and all)
Excellent! I would have liked to see the noise and output of a Stock Creality 24v fan for comparison. Some of the 4010 fans ordered from China cause thermal shut down. So not enough airflow.
Uh no, that's too much airflow. More air, less heat at the block, can't reach heat setpoint, shuts down thinking there's a problem
@@TheMidnightSmith That is interesting. The new fan has a center hub of 25mm while the Creality is 20mm. So I assume it can putout less air. Larger hub = shorter fins.
@@FilmFactry but what is the cfm flow? RPMs? Bearing type? All create variables. If you're getting thermal runaway, it's too much air blowing on the nozzle.
@@TheMidnightSmith This is the always on heatsink fan, not parts cooling. I very much doubt it was putting out too much air. The creality has larger fins. 4010 fan.
@@FilmFactry so if it's on the heatsink, I can't imagine it being a thermal shutdown. That's supposed to be cool, but nothing measures it. The only things measured are the heater block, and the actual main board in the printer.
Music is Run

đđ
If you want to put much sense on comparing noise fans, you could put y axis in log scale.
I need some work on my graph skills.
To test part cooling fans, you should test them for pressure and not by flow. Try to see how much air they can make pass through a small hole could also work, and they should be much better on this them the other fans
Thanks for your insight
Pressure would have been quite interesting Aswell. I can imagine that's where the blower fans are a bit better, because they have to get the air through some ducts.
Hard to test tho. Maybe measure the flow behind a small hole instead of a big canal like in this video?
Sounds interesting!
@@ChrisRiley Just print a "plug" for your orange duct and insert it about half way, with a 5mm hole in the middle. The wind reading will tell which one can create some pressure and blow through the hole the most air. Thank you for the testing!
Hey Chris Riley,
Can you shed some insight into what is the cause of the discrepancy with your measurements in comparison to the Amazon reviewer?
Does it vibrate a lot?
I was about to buy the SoundOriginal 4020 24V fan to replace the Creality's 4010 Blower that comes with the Ender 3 S1 Pro.
However, Amazon AU and Amazon Customers mostly claim it's a LOUD fan.
You got it listed as being one of the most silent for 24V.
They're all so close, it would be hard to say. Maybe quiet for a 3D printer?
@@ChrisRiley Thanks for the response. I will purchase the SoundOriginal 40x20 and test anyways.
3d printing is such an expensive hobby.
to bad there was no default creality fan, like for an ender3 hotend, i broke a fin off mine so replacing it is my highest priority and having a comparison would have been awesome
I thought about doing some more stock fans, that might be the next test.
I just found this channel!
Can you please redo this test but istead with 40x40x20mm fans?
I would like to see Sunon dominate the table once again lol
Great channel btw
I know I'm stepping off boundries but if you get the chance can you test which is the best 40mm fan for alphacool 40mm server radiators
Thanks, I'll see what I can do
I'm a fan... Of your CZcams!
hah lol true
đ Thanks!
Hey, can you make a video about of the high speed voron core xy printer?
Yes, I have one in the works.
