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!

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.

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.)

@Deiphobuzz

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..

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.

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.

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.

6:22 “the opera Sydney house” 😂 You have to admit that was pretty funny

tri-fangle dangle, which frequency would you like? "ALL OF THEM!"

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.

That lavender purple color makes any fan look pretty

8:19 interesting exhaust pattern.

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.

Very cool fan designs....all of them!

You know it's been a while since I came to your channel. And this thumbnail made me think you were the rock

Sydney's opera always remind me of dune 2 wind turbines

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!

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.

The tri fangle dangle really does it for me. Coolest one here.

Awesome Video

It'd be interesting to check the static pressure of the turbin fan.

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.

I was really impressed with the City Opera house fan! Very creative and still moved some air!

It’s crazy to look at the background of The Fan Showdown and remember everything, so many memories. Seasons of member berries

Wow, I cannot believe the tri fangle dangle worked well! I thought that was going to be crap... But I ate my words, thoughts, inner dialogue.....

I dig your shirt, took me almost the whole episode before I noticed the silhouette.

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.

the opera house spinning at 2000 RPM is so silly, in the loveliest way

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! 😁

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....

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

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!

The Tri-Fangle kinda reminds me of the original rims on the Saab 900 Turbo :D

the tri fangle had an intresting stripped patteren on the smoke output

You can actually see the patterns of the tri-fan producing, very cool!

The trifangle-dangle sounded better than the previous, but the Sydney Opera fan sounded even better!

So cool how you talk about functional parts (3d printed)

We have been doing this a long time but it never gets old

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.

I want that triangle fan just for the looks. one of my favorites

I'd like to see a contest where entrants start with a top-5 GOAT design and try to improve on it.

Love that editing technique around 4:25 where the pictures morph into one another

Got to enjoy just how well the stock fan holds up.

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

I wasn't even wearing headphones and my ears were destroyed

the Sidney opera house makes a nice relaxing sound.

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

OK, I need to build the turbinator for myself because I love it.

Very apt that the Sydney Opera House sounded better than the others.

That ad read was a plosive 4d experience.

Unsurprisingly, the Sydney Opera House had the best acoustics in this episode.

I like how the Nakreous's sound adr'ed in

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.

Tri fan reminds me of a pedestal fan I saw years ago with three blades and that thing also sounded like a propeller aircraft.

The Turbinator is cool and all, but a real-world one is designed to slow down and compress air, then heat it with fuel to get the speed up again. Here, no heat is added, but the fan motor helps a little of course. So yeah, it shouldn't do well, and it doesn't...

You know what could be fun with the Turbinator? Find a Delta or Sanyo-Denso fan that can run 6000+ RPM and strap that bad boy on.

Off topic but, that shirt is dope bro I like it

Ideal travel fan for flying!!!

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

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.

It worked better than I expected, too. It was created purely as a meme fan (I also created the Flexi-fan in season 3).

Even without headphones, the terminator is painful on the ears.

Is there a spreadsheet somewhere with the fans performances and links to their designs? Would love to see what has performed the best

the turbinator turned on my tinnitus.

Only the best fan at that particular rpm. I've been waiting forever for you to do some higher RPM tests,!!

Still in the top 10 let's go 🥳

The turbinator could do a lot better with a proper seal between components.

The Turbinator cross section looks like the cross section of a rocket engine turbopump.

The turbinator is just a non fuel jet engine 😂

loved how opra house sounded

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

I love the Opera Sydney House lol

hey well the Turbinator may not have moved the most air, it was THE LOUDEST - BY FAR!!!! at over 71db the NEXT CLOSEST was at 54.5db !!!! It skipped RIGHT OVER the 60's!!! WOW!!!!

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.

Danish Design always timeless

Have you tried to print all the props in the other orientation? you would not need support on the inside (except the Sydney one)

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.

"without furhter ado" - proceeds to cut to commercial. Bruh xD

i think if the jet engine fan was sealed better it'd prolly be a top fan contender of all time

Always stay for the smoke testing

Guess you could say Gumus was a big fan of the architects' work

The noise from the Opera house fan was definitely the least annoying out of the lot. It also seemed to throw air out much cleaner and wider, which could be beneficial in some circumstances.
