Giving NOCTUA All The Turbo Noises | Fan Showdown S5E8

Pick up some Voxel PLA Pro for your 3D Printer
voxelpla.com
Most of the time a great PC cooling fan also is a quite PC fan. However sometimes the noise of something makes it just that much cooler. Everyone can agree nothing sounds better then a turbo in the boost, why cant we get that type of auricular feedback from a PC fan. Fun Fact we can.

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

​@@he8535 Oh, so I guess that would be hella good.

[@manitoba-op4jx]

[@warrenstamps6553]

Yes, a people's choice award

[@GumusZee]

Would I win? 😉

[@trebor_the_protogentvods]

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

[@simmaples3233]

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.

[@jeppe19961996]

The airspeed is probably not fast enough for these impeller-fan designs to work properly. None of these turbo fans has really excelled..

[@ducttapeengineer]

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.

[@Hephera]

gaskets would make a very minimal difference. its just a bad design

[@TheHungrySlug]

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!

[@GumusZee]

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.

[@PabloEdvardo]

I immediately was like "holy cow the shitpost fan is working!"

[@nick91884]

Great job, I also was surprised at the performance, highly respectable.

[@void_snw]

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

[@beartankoperator7950]

The pressure was probably high even though the speed and volume was low

[@FixingWithFriends]

Also, kind of slow. Gaskets might help a bit, but with the 120mm frame and fan motor limitations....

[@Deiphobuzz]

removing the motor and adding a drone motor would be cool, see it spin at 15k lol.@@FixingWithFriends

[@AHSEN.]

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

[@TheRealAlpha2]

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..

[@gravspeed]

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.

[@qumefox]

Yep, was going to say that, Centrifugal compressors like that are.. well, compressors. They're designed to create pressure, not really high flow rates.

[@fuxseb]

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.

[@MaraficeEye]

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

[@Nobe_Oddy]

ohhh PHOOEY!!! I came here just to point out his lysdexic mistake too :)

[@Be_Spectacled]

I was about to mention this too lol

[@cqbSarge]

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

[@Riccorbypro]

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.

[@JohnnyWednesday]

I'm happy with fans to be honest - Steve is lovely but sometimes you just want to see fans do battle out of context

[@dlanm2u]

You could send the top 5 fans to LTT and have them auctioned off for charity when you needed them back

[@FixingWithFriends]

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)

[@station240]

@@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.

[@thesoupin8or673]

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!

[@Cybernetic_Systems]

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

[@Renagede77]

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

[@Wormenstain]

It had gasket but what it really need is 4 screws.

[@dannybrennan31]

I would love to get a retest with 4 screws. It obviously has a gasket

[@TheHungrySlug]

If he had at least used a screw to hold each corner and not just 2 corners. may have helped.

[@Venom450hp]

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

[@20bluebug]

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

[@NathanOakley1980]

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.

The Trifangle Dangle being a sleeper hit!

[@sparkplugbarrens]

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

[@samuelurban6132]

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.

[@lady_draguliana784]

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!

[@GetFitEatRight]

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

[@alisdairherd9501]

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

[@markanderson3740]

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.

[@Maccaroney]

I love this show.

[@gurttron]

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!!

[@TheTyisawesome]

Exactly that was cool it was making some thrust remind me of an airplane prop

I think there's room to improve the shape of that fan for better laminar flow while still having three blades.

[@mysticvirgo9318]

@@fluffy_unicorn859 the fewer teh blades and/or the slower the rpm ( not issue in these tests) the lower the frequency of the sound :)

Thanks! It's the second time I made it to the thumbnail - I also created the Flexi-fan in season 3

[@gearjammer3200]

[@drewoxmix8808]

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

[@Workingclassdad]

Need a compilation video of all smoke tests ever.

[@audiocrush]

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

[@speeddemon1092]

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.

[@bismuth7730]

And kiss Noctua sponsorship goodbye? I dont think so

[@jttech44]

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.

[@parkerazz4385]

Always stay for the smoke testing

[@kb-elmo]

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

[@BVLVI]

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

[@filanfyretracker]

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

[@aarontrupiano9328]

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

[@Archi2g]

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.

[@utilka5415]

[@Valfaun]

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

[@Tomas_Stec]

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

[@infusedj9498]

the turbinator turned on my tinnitus.

[@edwardnedharvey8019]

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....

[@HelloKittyFanMan]

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.

[@Leadvest]

That ad read was a plosive 4d experience.

[@SamSeama]

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

[@shaneeslick]

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.

[@KiyoshiKatu]

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?

[@AquaticRobotic42]

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

[@aethertech]

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.

[@TechRIP]

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

[@LauraDelvecchio]

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

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.

[@MrAszabo]

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.

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!

[@jimbo-dev]

An air pressure test would be interesting comparison to add alongside airflow test 🤔

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

[@krakhedd]

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

[@Roboseal2]

The turbinator is just a non fuel jet engine 😂

[@NN1Ckl.]

I wish you would/could do a static pressure test on the fans. The turbinator should be best in that aspect

[@AaronShenghao]

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...

[@blaineburgess]

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.

[@EweToobUsername]

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.
