Hi, Gumus here. Thanks for featuring the Sydney opera fan, and on 50th anniversary of it's opening, no less! I was really surprised by the performance, it was created purely as a meme / "would that even work" kind of thing. Same as the Flexi-fan I created back in season 3. I'm glad it worked out and printed this well. I spent over 40 hours on this, mainly battling my CAD skills and researching the curve shapes. I had many 2D and 3D references, but in the end I created all of it from scratch. I learned a lot during the process and it even came out decent.
Agreed, the air also seemed to not desire getting pulled into the intake. My guess is that the intake/ velocity stack is to long while not having a trumpeted end, where it should curl back on itself. Pure conjecture though.
It wasn't going to perform very well with the air having to make right angle turns to flow through. Printed PLA doesn't have a smooth enough surface and too much energy is lost to friction. If you look at the top performing fans, you'll see that they all have very little to no restrictions to flow.
If he had at least used a screw to hold each corner and not just 2 corners. may have helped. since you could see the fog escaping it in the smoke test. it was made with 4 holes and only got given 2 screws. Also the print quality of those prints was NASTY!
The turbinator might not make as many cfm, but I bet it has the best static pressure. That would be an interesting set of tests. See how high they could lift a racquetball in a tube or something.
Yep, was going to say that, Centrifugal compressors like that are.. well, compressors. They're designed to create pressure, not really high flow rates.
A metric ruler, an U-shaped pipe and some water would be a good pressure gauge. In most datasheets, the unit of static pressure is milimeters of water (mmH2O), so no unit conversion required.
The Opera House did way better than I expected, cool little design! The tri-fangle dangle was even more surprising, as usual the flow pattern was my clue that it was doing well the fact that it produced the most airflow of these is impressive for such a simple design versus the giant turbinator. (the second you said the air had to turn 90 degrees, I had a feeling it wasn't going to do well.)
turbines never flow as much as fans do. they can build pressure though, which fans suck at. Look at a bouncy house, radial fans, turbos for cars vs a desk fan or old plane..
Hey, this series rocks! Crazy to see how far you've come. Just wanted to compliment the visual display during the smoke teating, as I think this was the perfect combo of showing the smoke, showing the fan, and clearly identifying the fan by name. Great work as always!
you should send the top 5 fans to Steve from Gamers Nexus and have him do a bunch of thermal testing and see how practical they would actually be in a computer... or just do it urself
He could do it himself, but cross-pollination of communities that would come with doing a collab with GN would likely be hugely beneficial for both. That and GN has the hardware to not only run thermal load tests like was done in early Fan Showdown seasons, but to test all aspects of the fan, like the difference in airflow with a restriction in front as opposed to behind the fan, what thermal load it could reasonably cool when attached to a standardised cooler (maybe have 2 options like they already have with the 2 thermal loads for testing the different classes of air cooler rn), etc.
I tried to get LTX to invite James but... I am pretty sure they wouldn't care about a suggestion from a random guy. Especially about a 'small' youtuber. ...Especially now, seeing his view on things. Even reading an email suggestion/feedback would be a waste of money. I bet we could persuade Paul to do something with James. (Also, @Dlanm2u lol)
@@dlanm2u LTT woudld lose the Noctua hub you included, fit all the fans to leaf blower and complain how crap they were and a complete waste of filament.
6:00 'Excellent acoustic sound quality' As someone who has been at the Sydney Opera House MANY times both as a performer and an audience member - the acoustics have been famously bad. I remember seeing somewhere that as originally designed, the Concert Hall would have had decent acoustics but as manufactured... yikes. The original solution was to put 3 sets of transparent circular sound baffles (halos or donuts, depending on how rude you felt) above the stage to redirect sound towards the audience rather than the beautiful ceiling. As this was still suboptimal, a veritable FOREST of microphones and speakers was also hung from the ceiling. Further refurbishments were finished in mid-2022 which replace the donuts with pink metal petals (that look eerily like tongues) which can be raised, lowered, or angled in various ways for optimal performance. Various wall panels have also been adorned with some sort of wave interference pattern which does something to do with the reflections but, more importantly, looks VERY COOL. It's still not perfect - it's hard to hear left and right of you in the choir stalls, and there are some dead spots on the stage - but the new acoustics are much better. Other improvements they made include enlarging the wings (handy for fitting an ensemble waiting to go onstage), turning the entire stage into a lovely set of hydraulic lifts (instant risers for your choir/orchestra), and adding RGB strips around the entire edge of the ceiling (gamer factor +1000). Apologies for the long comment and lovely fan!
Video Idea: Steve from GamersNexus had an extremely interesting discussion with a Noctua engineer about their upcoming 140mm next Gen fan. I would be very interested to hear you discuss fans with some of the key fan players. Love your stuff.
I find it funny you didn't expect the tri-fan to do well and it ended up doing better than all of them 😅 **Edit** Wow, this is the most likes anything I have ever written has gotten!! Thanks Guys!!
the trifangledangle would benefit by utilizing coanda effect on the edges that project into the lee side of the axis by rounding those over like a wing, with a slight hump forward to compress the air against the curved face leading into the capture zone of the windward fin behind. it would cut down the noise as well.
I'd love to see a side-by-side of each fan's airflow unrestricted v. restricted (through a cooler sink) as well as adding a way to test each fan's max static pressure developed!
i dont watch all this guys vids..... but the ones i do watch have always been well put togther. pretty niche content but this guy deserves a good number more subs! keep it up dude
8:48 you should've used 4 screws to hold the shroud on, there's an obvious gap where air is escaping that could've been reduced substantially by just putting all 4 screws in... probably the way derek thought you'd do it :P
Surprised the Tri-Fangle Dangle did best. I had pegged either the Flower or that Turbinator thingy. And just to mention the last one, reason I had to watch this episode at once when I saw it, was the Sydney Opera House fan! 😁
Interesting that the 3-blader won this round especially pushing through a radiator. Fans with gaps that big between the blades typically dont do that well with pushing. I also have a suggestion for next season: Instead of using the A12x25, get one of those 38mm thick 5000+ RPM Deltas or Nidec Servo fans and use that as the "host" fan. The challenge will be again, to move air, but also which is the quietest, and which will survive spinning full speed. I ***highly*** recommend that if you do this, you set up some sort of multi-layer plexiglass blast box around the testing area should a fan let go at full tilt.
The motor in the 5000 RPM deltas would grenade most of these designs, and the designs that survived would have clearance issues. Not worth the trouble. There's a reason noctua, and most other fans, don't spin ultra fast, but instead are hyper optimized to efficiently use a more limited RPM range. That's why this challenge is interesting.
I have never seen airflow out the exhaust as satisfying as that turbinator. 8:34 It looks like a nuclear power plant steam exhaust chimney. Just a solid column of smoke moving in perfect smooth flow....
The sound comes from the interferance between the roter and stater. The sound is still there if you remove the intake shroud. Also I highly doubt that turnbinator is still rotating at 2000 RPM with all that mass and resistance from the compressor...
I'd really like to see a static pressure test, especially on the turbinator I believe that thing should reign supreme above all other designs when it comes to that metric
One thought on turinator is the large change in cross sectional area behind the exhaust duct. This will create local low pressure around the center cone, likely causing separation and a big eddy in the center of the exhaust, thus making turbulence and slowing flow. I wonder if you had separate intake vanes on the exhaust duct if local fast flow from the perimeter might pull more air in and improve performance… hmm ok now im tempted to make an entry
At this point I wouldn't be surprised if you can just make an ASMR Livestream of just the smoke test that randomly switches between different fans. A separate meme stream could be just the fan sounds.
man your print quality really went down since i watched this last. . . like it one thing to not sand or finish any of them but what happened to that tri wing one? example: top wing at 2:57 shoulda reprinted that one homie that's 1/3rd of the fins
That triwing can could do great as a cost effective fan if optimised to be a hollow as possible. Material savings over millions of fans would be substantial.
G'day Major, 🤔Just wondering if we can get a Showdown of the Best Performing that are completely contained in the 120x120x25 frame size all reprinted on the new printer ??? Growing up in & around Sydney I knew exactly what Gumus had designed, SOH is a very Strikingly Beautiful Building & the Acoustics in the halls create an amazing concert experience.
It would be incredibly interesting to see the smoke tests in super high frame rates. Not sure on the cost of an upgraded camera for that, but I 100% think it would improve data collection capabilities and add more interesting visual analysis for you and us the viewers.
I wonder if there’s a good way to limit the flow at the end of the tube where you measure flow, to have a “no resistance” flow rate and a “resistant” flow rate. Maybe a butterfly valve at the end, and a simple pressure differential gauge. But I don’t know if you would want to maintain a specific static pressure or maybe a non restrictive flow specific static pressure. Then we’d be able to see which fans run the best with resistance. Maybe something to see next season?
I like the Tri-Fangle Dangle personally! I love spinning designs with three main bodies, like 3-blade propellers or 3-Spoke wheels! I love that shirt too, and I think I need one! Can you point me to where you got it from?
You know. Some of these slow air moving fans might actually produce a lot of static pressure. I think it's time to start measuring that. That way you can have 2 charts. One for airflow which is good for the case fans. And static pressure chart which would be good for radiators or coolers.
I would also like to see air speeds for open air versus restricted (e.g. on a radiator). However, I don't think there's much value in measuring the static pressure directly. Static pressure alone isn't important - it's simply a means to forcing air through a restriction. Fans with low static pressure won't have high air flow through the radiator regardless of how high their airflow would be in open air. Measuring the air speed under a typical resistance gets more directly to what you want to know rather than having to try and infer that from the static pressure. Also, these static pressures are very low. I bought a manometer for myself for testing static pressure in a similar blower and it hardly even measured on the scale. Manometers with that small of pressure sensing are quite expensive.
Impressive results from the Tri-fangle Dangle. The smoke test looked especially good on it, cause the smoke was all being pulled into the center. I wonder if a penta-fingle dingle would be better or worse?
Is there a particular reason we stopped doing thermal testbench? I was always more interested in whether or not the fans could be popped into a wacky PC build than the specific aerodynamics.
Tri-Fangle Dangle and FLOW-er look really cool to me. Especially the FLOW-er... something about that design that I just really enjoy. I know fans generally use an odd number of blades for sound reduction, but now I'm wondering if it could also be hurting the performance somehow? Hmm...
from the smoke test the Turbinator looked like it was more high volume low pressure. Moved a lot of air but not at high speeds. Maybe if the disperser end was more narrow?
I'd like to see the Turbinator v 3.1 - with some double-sided tape or perhaps very thin foam padding, to seal it up a lot better I can't believe the Opera House worked so well, and that the Tri-Fangle Dangle worked at all. The FLOWer was very significantly smoother than I expected
You should retest the turbinator without its rear shroud as that rear shroud appears to be trying to increase open-air flow rate at the expense of pressure... And with trying to use it on a noticeably restrictive radiator, that drop in pressure by the shroud might be enough to drop the performance of the whole thing.
Maybe have a look at different new fans like the Apex Metal fans from Alphacool when they are available, there was also some low profile 120mm with a clear LED lit hub at computex but cant find it.
Have you ever printed the noctua blades in pla like you do the fan submissions, could the type of plastic used make the performance worse of the original design?
You should test for pressure as well with the terbinator as a turbine like that isn't ment to produce high speed air but rather ment to compress it. You can see it is producing at least some pressure by all of the air escaping form the sides 8:43
The Turbinator was clearly leaking during the smoke test because not all of the corners were screwed down. Was that also the case during the air flow test? Being a compressor, it's critical that it is well sealed, otherwise the high pressure is just going to force air out through all of the cracks.
Our Gov is happily running our country into the ground, but Sydney, Australia has the best looking harbour on the planet. The bridge and the opera house strike a great contrast that rarely works when combining old with new aesthetics.
Is there a way to measure the turbulence of the air coming out in a way that can be easily compared between fan designs? I think it would be interesting to compare that.
hey designer of tri fangle, you think of taking the tri fan and just copy paste the same fan over it just rotate it until it's a 6 blade design? I mean I think the static pressure benefit is from the long swing/angle of the blades so I am unsure how 6 blades will mess with the aerodynamics. But maybe give it a go.
@@LightningJR I am designer of the tri-fangle dangle, I was (pleasantly) surprised to see it did so well. I will do another iteration for sure. I think 6 blades is too much because of how the blade face blends into the next, might reduce the effect. I'll try a 5 blade but it it looks too crowded I'll go with 4. It seems more blades is not always better as evidenced by the 8 blade FLOWer. What do you think of a three blade but extend the width of the tips to create more blade surface, like double the width of the blade at the tip?
@@FresherDenamug man if he just reprinted yours you could move up at least 4 spots on the board. the top wing on the 360 shot looked so scuffed. surface area and angle upgrade maybe. Do just a tiny change and hope for a better print next time i guess. you got the best 3 wing design IMO
I see, very interesting about the blades. Yes good idea on the width of the tips. It's a very cool design. If I had to explain how it looks it would be a ninja star with a blur as it spins in slow motion. You can mess with the "blur" extending it or even shortening it, idk, maybe you have already tried it. the shape has a kind of a triangle shape but with some curves, idk if you tried a no curve/straight line blade design, or putting an even greater curve on each blade. @FreshDenamug
Can i suggest a future episode? As your abiliry to print becomes more and more refined, maybe you do a top tier rematch? Reprint the top 5 or top 10 best performing fans, and re-test them.
The FLOW-er really should have been designed with 7 or 9 blades. The problem with using multiples of 4 specifically is that the fan blades align with the motor supports all at the same time, making it louder. I'm actually a bit surprised Noctua went back to 4 evenly spaced supports, when their previous design had such a clever unevenly spaced 11 support design. But, knowing Noctua, I'm sure they tested every possible variable before settling on the current A12x24 design.
Just using my eyes, I feel like the turbonator has unrealized potential. That setup was zootin' air out the back in a straight line. It felt like it had a specific purpose of sending fast moving air a decent distance. That is a fan setup that would perform great as unrestricted intake. The sound however, gave me a headache.
Bruh, Sydney opera house was designed like that to resemble the sails of a ship, which, according to the architect, was done to both seamlessly blend into the surroundings and to make something unique
Maybe a dumb question, but if you had a big enough tank and powerful enough compressor to keep up, how good would just a regular air compressor, and its regular hose and nozzle be for cooling?
A lot of the prints done have very rough edges due to the issues with PLA printing. If a better printing method/material were used that gave properly smooth edges, would the reduction in turbulence also lead to a reduction in noise as well? It always feels a little unfair to compare to expertly manufactured Noctua blades versus the much more roughly manufacturing methods used on the show. I enjoy it greatly, but would love to a video series on exploring what could be done to improve print quality while still being within the DIY scope of this series!

i think the terminator needed some gaskets to actually do well, you could see air coming out from the seams between each piece of the fan
Agreed, the air also seemed to not desire getting pulled into the intake. My guess is that the intake/ velocity stack is to long while not having a trumpeted end, where it should curl back on itself. Pure conjecture though.
The airspeed is probably not fast enough for these impeller-fan designs to work properly. None of these turbo fans has really excelled..

The pressure was probably high even though the speed and volume was low
Also, kind of slow. Gaskets might help a bit, but with the 120mm frame and fan motor limitations....

Fantom of the Opera House sprung to mind as a name!
The “Intake Tube” on that first design is called a Velocity Stack, it acts as a venturi tube and accelerates the air being taken in.
I wonder if there’s a good way to limit the flow at the end of the tube where you measure flow, to have a “no resistance” flow rate and a “resistant” flow rate. Maybe a butterfly valve at the end, and a simple pressure differential gauge.

The trifangle-dangle sounded better than the previous, but the Sydney Opera fan sounded even better!
We have been doing this a long time but it never gets old
You know. Some of these slow air moving fans might actually produce a lot of static pressure. I think it's time to start measuring that. That way you can have 2 charts. One for airflow which is good for the case fans. And static pressure chart which would be good for radiators or coolers.
I would also like to see air speeds for open air versus restricted (e.g. on a radiator). However, I don't think there's much value in measuring the static pressure directly. Static pressure alone isn't important - it's simply a means to forcing air through a restriction. Fans with low static pressure won't have high air flow through the radiator regardless of how high their airflow would be in open air. Measuring the air speed under a typical resistance gets more directly to what you want to know rather than having to try and infer that from the static pressure.
Also, these static pressures are very low. I bought a manometer for myself for testing static pressure in a similar blower and it hardly even measured on the scale. Manometers with that small of pressure sensing are quite expensive.
Impressive results from the Tri-fangle Dangle. The smoke test looked especially good on it, cause the smoke was all being pulled into the center. I wonder if a penta-fingle dingle would be better or worse?
Got to enjoy just how well the stock fan holds up.
They Sydney Opera House has no business moving that much air and being that quiet
Have you tried to print all the props in the other orientation? you would not need support on the inside (except the Sydney one)
The turbinator could do a lot better with a proper seal between components.
Is there a particular reason we stopped doing thermal testbench? I was always more interested in whether or not the fans could be popped into a wacky PC build than the specific aerodynamics.
Tri-Fangle Dangle and FLOW-er look really cool to me. Especially the FLOW-er... something about that design that I just really enjoy. I know fans generally use an odd number of blades for sound reduction, but now I'm wondering if it could also be hurting the performance somehow? Hmm...
that would be so cool side by side. the same surface area and angle of attack just one less wing
Could we bring back the tachometer. I know it's not a measure of the usefulness of the fan, but it's another cool data point.
Perhaps the turbinator was too much load for the limited power of the a12x25 and it could be improved by less blades and more speed.
from the smoke test the Turbinator looked like it was more high volume low pressure. Moved a lot of air but not at high speeds. Maybe if the disperser end was more narrow?
I'd like to see the Turbinator v 3.1 - with some double-sided tape or perhaps very thin foam padding, to seal it up a lot better
I can't believe the Opera House worked so well, and that the Tri-Fangle Dangle worked at all. The FLOWer was very significantly smoother than I expected
You should retest the turbinator without its rear shroud as that rear shroud appears to be trying to increase open-air flow rate at the expense of pressure...
And with trying to use it on a noticeably restrictive radiator, that drop in pressure by the shroud might be enough to drop the performance of the whole thing.
Whoa, nice harmonics on the Turbinator - you see nice sharp peaks at 2 kHz, 4 kHz, 8 kHz…
I bet Tom came in pretty hot with his fan even if we _did_ see that episode.
I bet this is that series even if we're not new.
Nice choice of Aircraft you got on your shirt.
Maybe have a look at different new fans like the Apex Metal fans from Alphacool when they are available, there was also some low profile 120mm with a clear LED lit hub at computex but cant find it.
Have you ever printed the noctua blades in pla like you do the fan submissions, could the type of plastic used make the performance worse of the original design?
You should test for pressure as well with the terbinator as a turbine like that isn't ment to produce high speed air but rather ment to compress it. You can see it is producing at least some pressure by all of the air escaping form the sides 8:43
The Turbinator was clearly leaking during the smoke test because not all of the corners were screwed down. Was that also the case during the air flow test? Being a compressor, it's critical that it is well sealed, otherwise the high pressure is just going to force air out through all of the cracks.
the tri fangle had an intresting stripped patteren on the smoke output
Only the best fan at that particular rpm. I've been waiting forever for you to do some higher RPM tests,!!
That title really had me expecting whooshing and fluttering 🥲At least there was some whistling.
Great video, pretty disappointing results though. LOL. DRAGONWING!!!
Our Gov is happily running our country into the ground, but Sydney, Australia has the best looking harbour on the planet. The bridge and the opera house strike a great contrast that rarely works when combining old with new aesthetics.
I'd like to see a contest where entrants start with a top-5 GOAT design and try to improve on it.
Is there a way to measure the turbulence of the air coming out in a way that can be easily compared between fan designs? I think it would be interesting to compare that.
i was impressed with the tri fangle. It looked to me to have some very solid static pressure. I like it, that design needs to be iterated on
hey designer of tri fangle, you think of taking the tri fan and just copy paste the same fan over it just rotate it until it's a 6 blade design? I mean I think the static pressure benefit is from the long swing/angle of the blades so I am unsure how 6 blades will mess with the aerodynamics. But maybe give it a go.
@@LightningJR I am designer of the tri-fangle dangle, I was (pleasantly) surprised to see it did so well. I will do another iteration for sure. I think 6 blades is too much because of how the blade face blends into the next, might reduce the effect. I'll try a 5 blade but it it looks too crowded I'll go with 4. It seems more blades is not always better as evidenced by the 8 blade FLOWer. What do you think of a three blade but extend the width of the tips to create more blade surface, like double the width of the blade at the tip?
@@FresherDenamug man if he just reprinted yours you could move up at least 4 spots on the board. the top wing on the 360 shot looked so scuffed. surface area and angle upgrade maybe. Do just a tiny change and hope for a better print next time i guess. you got the best 3 wing design IMO
I see, very interesting about the blades. Yes good idea on the width of the tips. It's a very cool design. If I had to explain how it looks it would be a ninja star with a blur as it spins in slow motion. You can mess with the "blur" extending it or even shortening it, idk, maybe you have already tried it. the shape has a kind of a triangle shape but with some curves, idk if you tried a no curve/straight line blade design, or putting an even greater curve on each blade. @FreshDenamug
for the tri-fangle-dangle.... can the maker do this so it can be RGB supported??? i would love to have these!!!
Did I black out or was there only 1 camera angle for the Tri Fan's smoke test???
these almost need a "doug score" to balance subjective awesomeness, creativity, and performance
Thhhhiiiiissss... Is the turbinator
Can i suggest a future episode? As your abiliry to print becomes more and more refined, maybe you do a top tier rematch? Reprint the top 5 or top 10 best performing fans, and re-test them.
the Sidney opera house makes a nice relaxing sound.
The FLOW-er really should have been designed with 7 or 9 blades. The problem with using multiples of 4 specifically is that the fan blades align with the motor supports all at the same time, making it louder.
I'm actually a bit surprised Noctua went back to 4 evenly spaced supports, when their previous design had such a clever unevenly spaced 11 support design. But, knowing Noctua, I'm sure they tested every possible variable before settling on the current A12x24 design.
Just using my eyes, I feel like the turbonator has unrealized potential. That setup was zootin' air out the back in a straight line. It felt like it had a specific purpose of sending fast moving air a decent distance. That is a fan setup that would perform great as unrestricted intake. The sound however, gave me a headache.
Bruh, Sydney opera house was designed like that to resemble the sails of a ship, which, according to the architect, was done to both seamlessly blend into the surroundings and to make something unique
Maybe a dumb question, but if you had a big enough tank and powerful enough compressor to keep up, how good would just a regular air compressor, and its regular hose and nozzle be for cooling?
Could you please revisit the resin printed radiator? Pretty please
A lot of the prints done have very rough edges due to the issues with PLA printing. If a better printing method/material were used that gave properly smooth edges, would the reduction in turbulence also lead to a reduction in noise as well? It always feels a little unfair to compare to expertly manufactured Noctua blades versus the much more roughly manufacturing methods used on the show. I enjoy it greatly, but would love to a video series on exploring what could be done to improve print quality while still being within the DIY scope of this series!
