Giving NOCTUA All The Turbo Noises | Fan Showdown S5E8 

You should start a "fan favorite" section where ppl vote on their favorite looking fan

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

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.

Man the fog coming out of the back of the turbinator looks so solid and clean. love it.

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.

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.)

You could see the trifangle dangle doing amazing in the smoke test! That was funny to see.

Ah that classic building "Opera Sydney House" 00:06:22 Love ya MH! Keep up the fantastic work, love this series!

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

The Turbinator could've used a gasket. It was losing some airflow between the fan and the rear section where they were connected.

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!!

Waking up to find my v3 design made it into a showdown episode made my day. Thanks James! 🖖

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.

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!

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

I like to picture Major Hardware taking Major Bong Rips & blowing it at the Fans for testing

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.

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

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'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!

8:19 interesting exhaust pattern.

The Trifangle Dangle being a sleeper hit!

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

I really appreciate the work you put into these videos! Its a pleasure to watch everytime

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.....

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

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

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.

That lavender purple color makes any fan look pretty

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

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

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

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

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

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

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 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....

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

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

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

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

That title really had me expecting whooshing and fluttering 🥲At least there was some whistling.

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

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

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!

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.

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

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...

Fantom of the Opera House sprung to mind as a name!

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

Awesome Video

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

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.

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

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

Nice choice of Aircraft you got on your shirt.

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

the Sidney opera house makes a nice relaxing sound.

Whoa, nice harmonics on the Turbinator - you see nice sharp peaks at 2 kHz, 4 kHz, 8 kHz…

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 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?

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...

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.

trifangledangle looks like it'd make a good weedeater blade :)

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

Ideal travel fan for flying!!!

I love this show.

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

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.

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

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

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

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.

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.

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!!!!

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.

I love the Opera Sydney House lol

That ad read was a plosive 4d experience.

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'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

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

50th anniversary day today (opera house opening), good day for a video lol

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

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

Still in the top 10 let's go 🥳

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.

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.

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.

Always stay for the smoke testing

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.

Need a compilation video of all smoke tests ever.

I have never really optimized my old ass cheap Anet A8 3D printer and the quality looks way better than those fans here, which really surprises me. But the coating makes it look like a big difference, it looks really nice! As my initial purpose for the printer was RC planes and cars, air properties are quite important, mind sharing your process about the smoothing steps you did?

these almost need a "doug score" to balance subjective awesomeness, creativity, and performance

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 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.

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.

loved how opra house sounded

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