[@MrMikevida]

Great channel. Terrible sponsor.

[@foureye7058]

yikes dude

[@Skinnamarink.]

Honestly, youre a pos for shilling raid.

[@Skinnamarink.]

@@MrMikevida which in turn, makes the channel terrible.

[@EnderMalcolm]

The reason it's slightly worse to be pointy is that at re-entry velocities, you are beyond supersonic velocities and literally smashing the air apart as you hit it. Being "Rounder" or "Blunter" creates a sort of air dam in front of the object, pushing the air-smashing distance a bit further away, making things overall safer for the object. The downside is you end up with something like the Space Shuttle, which had an absolutely terrible glide slope due to all of the drag at supersonic and sub-sonic velocities. There's not much point talking about drag when you are hypersonic, because no matter what you do, it's going to be there in a very annoying amount.

[@jblob5764]

Exactly, a blunt edge forms a cushion of air ahead of the leading edge. If you had a sharp edge that was making direct contact with hypersonic air the surface temperature would soar extremely fast well beyond the melting temperature of anything we would be using. The shuttle is a great example. It's a terrible "plane" because it lacks a lot of lift, but it has to be that shape to have any hope of surviving re-entry. Same reason the Soviet knockoff looked almost identical, you can't out design the laws of physics you just have to do the best you can with your materials

[@wobblysauce]

The flying brick

[@stumpy990]

Believe it or not a parabolic nose cone has a lower Cd than a "pointy" cone

[@mariueg]

@@jblob5764 The Buran was very similar also because of "extensive espionage"

[@szurketaltos2693]

So when is a pointy nose better and when is blunt better? My understanding of "normal" everyday aerodynamics is that the best profile is a teardrop, then points are common for high speed aircraft.

[@RobBulmahn]

The Whaleoid seems less like a toroidal blade, and more like a regular blade with the center cut out. I'd be interested to see how a design with the tubercles but no cutouts would compare.

[@MrMartinSchou]

Yeah, I have a strong feeling that it's almost impossible to design a good toroidial blade without using fluid dynamic simulations and a lot of knowledge and experience in aerodynamics, which would explain why no KZbinrs have managed to make a good one.

[@mogergog]

You are correct. The design was only inspired by the toroid solution. It was not intended to be a full toroid. The top and the lower part of the loop have a different angle of attack. I haven't pre-tested it. This was just an idea, but now it's got my attention. :D

[@jasongreene303]

@@ImproveConditions If doing a true comparison over time, then the entire history would have to be thrown out since that would skew all of the new entries. Maybe a test to see how much it changes would be a good off season episode.

[@Eidolon1andOnly]

Pretty sure he already did an episode comparing a resin print with a filament one. He aslo did one about using acetone or other means of smoothing out filament prints. There wasn't any significant improvement in either case if recall correctly.

[@madsenbaum]

Pretty sure "Spoki" isn't referencing the word "spooky" but rather "spoke-y", as in it has a lot of spokes or maybe spikes. That's my take anyway...

[@jasongreene303]

I was thinking that also.

[@Ponderforge]

Thank you

[@docknives3792]

It is definitely referring to spokes and not spooks.

[@gringene_bio]

Or Spock-y

[@HDL_CinC_Dragon]

It bothered me so much every time he said "spooky" when it's *clearly* "spoke-y" lol

[@GeraldOSteen]

I'm so glad that this is still going. 6 seasons of this is fantastic, with real tests to help prove and improve design concepts. I wish we could do this with practically everything -- let the world of engineers and aspiring engineers alike disassemble and test everything, designing, conversing, sharing, and reviewing every component to find the very best we can achieve. I think RMS would be proud.

[@maxgood42]

looks like if the the Whaleoid and the RocketShip developed together we would eventually end up with the Dragon Wing.

[@ManjaroBlack]

It would be interesting to have a season where the fans are sound normalized; the goal being maximum performance per decibel.

[@geneolson6618]

Maybe in a future season of the fan showdown, there could be a "noise normalized" statistic. It seems to me that most humans have a certain decibel level they are comfortable tolerating. It is certainly a factor in my fan purchases.

[@CrescentX3]

Db(A) is actually a human normalized standard for measuring volume!

[@ghomerhust]

yep, set a noise cap, and test the fan at that cap, as well as full bore. depending on use case, you might want quiet, or you might want brute force! much like the noctua we know and love here vs the insane 5 amp delta fans or the blowimatron (11k rpm)

[@drinkoldcoke]

Not just noise in DBA, but frequency too. A noise at the same "volume" but a different pitch can be much more bearable. :D

[@HazewinDog]

The fans are all running at max speed, so you could easily turn down the speed as you would do with any other case fan, in order to match your preference. It's not possible to extrapolate results from one RPM or noise level to others, especially when the fan designs get as unique as on this show.

[@athmaid]

@@CrescentX3 yeah but if you look at the curve it doesn't exactly account for it accurately. It basically looks like an inverted parabola lol

[@KyleHansen93]

Hey man! It would be really cool to do a fan showdown recap episode. All the different testing rigs, all the season’s winners, and everything. It’s just been a while since this whole thing started and I’m sure a lot of people weren’t here for the beginning.

[@samsimington5563]

I almost lost my composure trying not to laugh at the Quagmire clip 😂

[@WindCatcherRC]

Whaleoid is still noisy because there is a pressure differential at the back of the fan blade with the braces that hold the motor.

[@seanabsher5577]

I saw the fake smoke get sucked into the center of the pressurizer so that is a sign that the center fans did work

[@shApYT]

Surprisingly a pointy car like the Lamborghini Countash is like a brick through the air compared to the blob that is the Prius.

[@seldoon_nemar]

The funny part about nose cones and school busses is that the Falcon9 nose cone can almost fit one inside! 😮

[@ragetist]

I almost got an aneurysm having to restrain myself from making a "your mom" joke.

[@WolfgangBrehm]

Nose cone design basics: Round when subsonic, pointy if supersonic. Round again if the tip starts melting.

[@emmamitchell1582]

Maybe you could place an image of each fan in the corner of the frame during the sound test

[@_stoni]

How have we not had a Gamers Nexus collab yet?! Willing it into existence!

[@enterusernamefuck]

10:12 Looking at the top 6, Andy and Tom are killing it! Nice work.

[@Mycr0bi]

Happy new year, ready to fan up!

[@shaneeslick]

🥳🎉 Happy New Year Cooper & the Major Hardware Family, Listening to the sounds I prefer the slightly louder & Lower Frequency HMMMMM from the Whaleoid over the higher Pitch of the Rocketship, When Noise is the consideration for me it's not only about db but the sound between a 😐hum & 👉😖👈scream that the fan makes.

[@waynelehndorfer9190]

I love your videos, you have been my inspiration and I just ordered my p1s bamboo 🎉

[@mahmoudiamir]

Great to see you keep doing this, i suggest you keep this competition on other things

[@lordpraedyth6990]

Look at all of you smart people, "Well you see pointy vs rounded..." and I'm just here loving the memes XD

[@stevensmith797]

blunt nose means a shock wave that sits out front just off the surface of the nose , meaning less heat because the atmo isnt touching the nose

[@ethanpschwartz]

Anyone else keep coming back for the smoke tests?

[@RichardLangis]

During my 1:1 this week, my manager and I discussed how having a Raid: Shadow Legends inline ad means you MADE IT as a KZbinr. Congrats!

[@ghomerhust]

sadly, because of how hard they push their ads on people, many influencers and streamers are going AWAY from them as a sponsor. one, who was a lead programmer at blizzard for nearly 2 decades, flat turned them down because of their predatory ad practices.

[@TheFallenAngel13524]

talkin about Pirate Software?@@ghomerhust

[@IIARROWS]

If you sponsor that shit, it means you made it as a shitty person.

[@stevethepocket]

From what I've heard, it really doesn't-they'll start sending you sponsorship offers as soon as they're aware you exist, which will probably be before any remotely reputable company has heard of you. It really only marks a turning point if they're the very first sponsorship you ever take. If you've been doing them for a significant length of time, it's more a sign that you've gotten desperate or that you did something to make all the other sponsors not want to associate with you anymore.

[@xartemis2147]

Wow the print quality has improved so so much, thank you everyone for the content!

[@joshuabrickel0]

aw fuck yeah, go walleyes!

[@wrxsubaru02]

0:03 You should have said its hard to believe how fast the years have flowed by. 😉😉

[@dwolvin]

Very surprised that the pressurizer wasn't an absolute siren.

[@BooBaddyBig]

Normies are wrong, most launch vehicles do better with a blunt nose during ascent because an optimised rocket trajectory usually spends a long time subsonic, and the optimum nose for subsonic flight is blunt (see almost any subsonic aircraft). Pointy noses work supersonically (see Concorde) though.

[@Somesortadog]

Hmm I thought it be prounounced spokey star, like wheel spokes.

[@hightde13]

Huh. Oddly I think I like the sound of the pressurizer the best. Even though it was louder it felt more manageable.

[@ghomerhust]

it was more of a blank drone IMO, something that easily fades into the background unless it's so loud that it's overpowering conversation or something

[@LeeMooEez]

Now the print quality is superb!

[@zoson]

Pleaes make a 30mm thick version of the A12x25 fan blades, and a 5mm spacer so you can do a 30mm to 30mm comparison agaisnt the phanteks t30!

[@huseyinbogazkaya9926]

Can you make a single episode for 40mm 24v fan blade for 3d printing. The noise level is very high. You may have a market to brand it and resell. Many fans out here!!

[@Simon_Rafferty]

I'd missed this! Great idea for a video series, turning it into a competition! Despite being a Mech Eng, sadly I know little about fluid dynamics - but it has inspired me to have a think about it at least. Is there a link to your spreadsheet of designs v performance?

[@CapnSnackbeard]

The longer the hull, the faster the boat. If those fins were shaped to be rounded at the front, and pointy at the end, passing the edge of the blade, it might cause "lift" along the edge of the "hull" as lower pressure systems are created toward the back of the blade, this might cause it to drag air back along the blade faster. ... or something.

[@DeetexSeraphine]

Whaleoid looks like it's got a good static pressure to it, I would'nt mind seeing that mounted on a Rad as a pusher.

[@4ntig3n]

Just a guess, but the Spoki Star has to do with spokes, like those found on the wheels of a roman chariot

[@chrisanderson2368]

I had a high efficiency (for the day) outdoor AC unit which had a semi-tubercle leading edge on the fan. Repeating semi-circle cutouts, about 5cm wide.

[@rootbeer666]

I think fans installed inside a cowl should always take advantage of it by supplying appropriate tips.

[@RaphaelTreza]

Can you make a fan where each blade is rotating on their long axis using individual motors? then make the fan spin

[@mbcommandnerd]

The Spoki Star actually sounds like it’s playing a musical chord if you listen closely during the sound test!

[@HelloKittyFanMan]

"...It's kind of a pain to handle." Haha, yeah, of course; it looks like you'd have to be holding onto a bunch of knife blades!

[@tutacat]

Windmills are turbines, fans are impellers.

[@TheGalacticWest]

thank god someone did it.

[@Thesaltymaker]

This is a wonderful part of the internet, I don’t think we’ve found peak fan yet.

[@Andy-df5fj]

The reason I feel that you'll never see tubercles used on anything other than experimental windmills is because the performance benefits they provide do not justify the increased production costs.

[@meanman6992]

That first one to me reminds me more of a boats prop I saw recently that was supposed to help prevent cavitation and so reduce noise and turbulence…

[@pankothompson5903]

would be neat with a special episode at some point with light designs like use a lit fan like the new deepcool ft12 fan or some other one with a frame that lights up, see what people could do with translucent prints. Maybe also a show and tell sort of thing people sending pictures and videos of their creations and you looking at them.

[@ghomerhust]

oh yeah a foggy or clear filament would be neat to experiment with, if those RGB fans have a nice hub like this noctua does. some aren't really able to have the fan come off without damaging the hub or bearings

[@bonniehammond9566]

I came to your channel to see stats on toroidal. My suggestion was going to be a golf ball texture. Mythbusters did it to a car and gained 20% efficiency.

[@aokihax]

Dope

[@youtubeSuckssNow]

I would love to see a short clip of the current leader before the smoke test so we can have an idea of how it should be.

[@minmogrovingstrongandhealthy]

Pressuriser basically looks like (or at least reminds me of) those rally wheel hubs that basically serve as a breaks cooler and cooler in general for the car itself in that area. Since metal heats up under force and pressure etc ... and race cars need all the cooling they can get.

[@jmashcomptech]

Excellent short explanation of rocketry

[@Reaper6973]

Have you considered getting one of those water based aerodynamic tanks with UV ink? It's be really neat to go deeper into how the various designs perform in one of those. Lots of work I'm sure

[@JoelMannerino1]

Hey! Much love to ya and the whole channel! I've gotten into peltier fans/stove fans. That's a whole new realm of balance. I put together one after purchasing one and trying to find balance to performance. Can you look into it for me? Also get your community involved? You do huge favors to all of us simply just doing what you love, why not expand the horizon just a bit

[@SaltyRad]

considering the sound profile and that its at least an average blade for air flow. the rocket ship seems like a viable product.

[@DeetexSeraphine]

Question. With your ever escalating advancement in 3D printing.... have you considered running some of the more difficult and/or complex models submitted through new trials?

[@LKLM138]

4 minutes or rocket cone ted talk. That was fun

[@DUKE_of_RAMBLE]

Welp, right out of the gate, we weren't on the same page! 😅 I thought Rocket Fan was beard on the *_Grid Fins_* so.... I was wayyy off lol

[@hellothisismax]

oooOOoo we tried testing tubercle turbine blades recently! The results were not fantastic, maybe we need to try toroidal tubercle turbine blades next 😂🐳

[@TlalocTemporal]

One of the reasons whales have tubercles is to change the chord of their flippers along the length. This reduces the stall speed and increases the stall angle, so the flippers are useful with more extreme manoeuvres but also good at cruising. Tubercles are also good at catching vortexes and sticking them to the flipper, further increasing the stall angle. Planes usually achive the same effect with tapered and twisted wings, but some also use *fences* and *dog teeth* to achieve similar effects without needing to manufacture lots of 3D curves. Fences are actually quite like the Rocket Ship fan (and the tubercle-shaped leading edge too). Most of these things are to extend the speeds/angles at which wings/flippers are still useful though. A steady-state system like a turbine might not benefit too much.

[@TheStonedSpidR]

You didnt mention that the pressurizer actually did as it was designed and I believe that your "spooky" star is actually spokey as in spokes of a bike maybe. at least thats how it looks like it was spelled.

[@Zunip182]

I think if you were to speed up the smoke test footage, put it on a loop, and you would have a better understanding of how they are drawing air. The whale one pulled so much more air than the rocket ship. To me initially

[@Deviled_EG]

Do you still have that old ender 7 because I will take it if you can’t get it to work. Why have some broken printer taking up space 😉

[@shawnmichaelis1609]

nice print quality! i almost thought those were resin printed

[@Pavlobot5]

The star one looks like Anubis's ship from Stargate SG1

[@Inertia888]

I was really hoping I'd get to see a Tubercles variation, but Toroidal Geometry on the same shape! It's my Birthday, It's my Birthday, It's my Birthday!!

[@chettiarsirusraj9501]

The Presureiser is certainly capable of keeping the air airflow more evenly uniformed throughout its entire blade's surface inside & outside while spinning giving whatever it's propelling forward/backward a smoother and balanced force of thrust keeping the vehicle more stable while in motion.

[@TheFredmac]

The spoki star would be a good design for an orchard sprayer.

[@Coastal_Cruzer]

The beard is lookin great

[@HelloKittyFanMan]

Wow, the toroidal quality of the Whaleoid did a lot better than I thought it would!

[@marsaustralis6881]

I think Pressuriser would have worked slightly better if it had a shroud or some sort of cowling around the front, given how much air it was throwing back out towards the front.

[@Thaumh]

@Bearkirb314 The Pressurizer might work as well as conceptualized with fewer fan blades?

[@fstani]

I wonder if it's valid to measure how much air is being pulled, not only pushed out of the fan, of course what's being tested is the ability to make air flow through a radiator and keep it cool, but if we wanted to test the ability to move the air out, for example a fan to remove the hot air from a case, I wonder if designs like the pressurizer would be better for the those scenarios

[@laukan]

It would be interesting if you spoke a little about how you managed to print these

[@samuelforsyth6374]

[@custos3249]

When's the last time I saw a rocket shaped like a school bus? Challenger.

[@IRMacGuyver]

You might say, the years start coming and they don't stop coming.

[@GamingOnArc]

With regards to the rocket shape discussion, I heard a joke once... "If women ran the pentagon, would rockets and missiles be shaped differently"?

[@SparklySpencer]

I think one column that would enjoy on your testing is RPM normalized results for the CFM and dBA

[@SparklySpencer]

I would also be interested in saying if the room temperature has any noticeable differences in performance. As you know warmer air rises easier and cooler air stays lower to the ground. Due to the atomic structure of the more free flowing warmer air and the more densely packed cooler air, technically you might have variations depending on which season of the month or year you tested them in. It would be nice to have a professional testing space.

[@NeoIsrafil]

Man...that smoke test of the pressurizer though, did you see the smoke behind? I wonder if maybe it's static pressure is superior... Could we start getting a smoke test showing with/without radiator? Cuz if they're better for radiators it's good to know for those of us who do liquid cooling.

[@akingkirby3609]

[@rossgirven5163]

Sorry to say but they are not toroidal blades as what was being experimented with. They are just flat blades with a hole in the middle! The blades should have a “twist” towards the tips.

[@Pentross]

It’s not spoki star, it’s biblically accurate throwing star

[@ShiroCh_ID]

so far theres nobody seems to beat A12x25 for all noise,RPM,FPM and CFM stats its either you beai it in certain category, looks cool or beat all but noisy

[@FuhrChris]

Redo the whale ode with the bumps just on the actual leading edge of both leading edges of the toroidal. Also delete that last outside on the leeding edge whale bump it's clearly in the taper off of the fan blade.

[@I0NE007]

I'm pretty sure the "Spoki" star is "Spoke-y" not "Spooky." Because all the different blades are "spokes." But we're going to need to hear some original-source confirmation.

[@codahighland]

I think "Spoki Star" is supposed to be read "spoke-y" and yes, that star has spokes.
