I can't believe my design (Captain Amerifan) made it on the showdown! This is one of my favorite KZfaq shows ever, so it's an honor. Mine sounded horrible & came in 2nd for the show & 11th for the season, but it was a blast just to see it on the show!! Thanks for all the hard work you do to provide us with such fun and interesting content.

I designed The Finger Killer. The blades on the fan are meant to look like this. The idea is to avoid low pressure on the back of the blades that push the air. Again, the idea is based on pure imagination and not any mathematics. I'm not an engineer, just having fun. Thanks James for the feature :)

When you had the turbo fan on during the fog test you still had it called the amerifan

9:20 the Turbofan is misnamed

9:17 Bit of an error showing the wrong name of the fan

You called the turbo fan the Captain AmeriFan during the smoke test.

Maybe the Finger Killer with adjustments to those aerofoil blades would do better.

9:17 the name of the fan isn't changed

I'm the designer of the turbo fan :D. Thanks for testing. It was a fun project late at night and i'm pretty happy with the results. The goal was to look good, not work good ^^

It's based on turbo fan Wheels that are on certain vehicles you can usually find them in like German touring car racing from like the 80s in the 90s

The turbofan looks more like an HVAC blower fan (squirrel cage)

One of my favorite shows on youtube. The fan show down!! Love seeing how they suck in and distribute the fog.

Hey for the sound of the fan try doing a sound spectrum analyzer to show where the sound is at.

I love the fanshowdown. Intresting every time.

Wonder how much better the fingerkiller would perform if it were better balanced and had an intake shroud.

Good call adding some space between the fan housing and the desk. Gotta isolate.

I would like an episode or maybe a small series of episodes of playing with different parameters such blade angle, number of blades, blade curvature, etc. Only changing one at a time.

I love the intertwined movie references 😂

The fact you actually gave the correct explanation of the brake cooler just shows the true dedication you put into your work. 10/10

Love this show. It's honestly better than most television and it's genuinely interesting

The Tesla rims have always been designed with aero in mind. They reduce the drag coefficient.

Tesla would've have designed the wheel to be a fan since the first gen model3 specifically came with a plastic wheel cover that looked like a fan for better aerodynamics.

Rims who is designed like fans are designed to cool the breaks better :)

It's actually perfect because not only do I get to watch an episode of one of my favorite series but I also needed something complete like lustre.

The Model S's Turbine-style wheels should fare better than the Model 3 used here, being based on an actual turbine itself.

I think the fingerkiller would be much better if run in revers! It's like a super high aspect ratio spoiler.

Even if they don't win, if they manage not to throttle under a stress test, they did a lot. And, if people wanted a unique fan, they'd have one for sure!

I would love to see someone make a fan based on Lamborghini Centenario's rims

Fan showdown is the video series I look up to most!! I'm always left wanting more, and waiting for the next episode like a kid waiting for the candy shop to open.

The 1980s BMW e34 M5 had these really cool wheels (style 20) that were known as "turbofans" because they had a separate faceplate with turbine elements to draw air in and cool the brakes. Love their retro look on an 80s BMW too

It's been so cool watching your production quality just go up and up since that first episode. :) Keep up the great work, thank you for the content!

New slowmo is dope, great job on that. As usual, whole series since the start is one of most amazing ideas we had around. Thanks for the work, for all designers and for you for making the designs become a reality. And for making it in so entertaining way Sir!

The captain amerifan almost makes a sine wave sort of sound. very interesting.

Haha I got so confused initially when I saw the Captain Ameri-Fan twice and the flow pattern changed. Awesome videos keep up the good work!

As always. Awesome video and love how you push your followers to grow and experiment. It’s awesome

Im so impressed by how much new designs are being tested even though were in Season 3

I showed your channel to the engineers I work for, and they love everything you do!

Absolutely awesome smoke test on the rally hubcap

Wow the captain amerifan made a shield with the smoke. That's pretty cool!

9:30 The fan was labeled wrong but no big deal. Love what you do sir. Also thank you to all you wonderful fan designers out there who contribute to this! I love the turbo fan even if it didn't perform all that well. I wonder if tweaking the blade design and number might boost performance...

I love this show. Always happy to see a new episode.

Funny! In the early 1970's, 'Mag-wheels' spokes were marketed as having 'wind-turbine' powers that helped keep brake-pads cool! Discussions about the low mass of the mag-wheel took a back-seat to how they were going to make 'brake-fade' a thing of the past. Brakes get hot, lose their grip. The 'turbo-fan' action of the wheels was supposed to prevent all that! Ah, nostalgia...

I'm a bit of a "concept whore". I have been a mechanic for 30+ yrs, so I watch pretyy much anything automotive related. i am also very interested in PC's and computers- so this series scratches both itches in an oddly satisfying way. To see the concept as simple as a fan deconstructed to such an extent, and tested is awesome. I may have to add proper CAD (I have been using the other CAD- Cardboard Aided Design for decades) back to the skill set (Briefly held a job as an automotive engineer with GM in the 90's, so most of what I know is useless/ outdated) and give this a go. Excellent job on an excellent series.

The turbo fan might be cool to use as a top exhaust for a case. also ideas for next season - delid and liquid metal the cpu or get one of those custom gpu coolers where you can attach 120mm fans.

Here since episode one. My head is straight up spinning.

Captain Amerifan sounded like the initial note played in the severe weather warning from the National Weather Center 😂

Amerifan looks more like a clay pigeon and with those performance numbers, I think it would be better suited as a shotgun target too lol.

You should look into the SAAB 10 spoke turbine wheels. Those are really worked like turbines. There were two left and two right rims and you had to take care not to mix them up. Or the car might go sideways at high speeds.

Plus another idea… maybe some programmable rgb strips running underneath the smoke test for future? Having coloured “runway” type lights lighting up the fog would be AWESOME

As an engineer who designs, simulates and tests this type of fan everyday I love the series. I chase aero efficiency and performance, here we just do things for the sake of doing them.

Finally someone made a proper turbo fan!

Another great one my friend!!

What could be interesting is to see a spectrum analysis of the sound the fans produce. As different frequencies can be more or less intrusive for a given volume level.

You got thiner!! Nice! And great video as always!!!

I love how you've created a community of people who are encouraged to think about engineering and see their imagination made real

This series gives me life. Greeting from the clinic

Tesla designers definitely wanted to cool the brakes. That car was made to be great around a track. Randy Pobst was part of the design team for the racing aspects.

Like these series! Maybe include a FFT of the noises to visualize the differences and peculiarities?

Hi, so small things i've noticed since you've been asking for returns on the video quality For the main camera/ the talking head camera : It's still a bit dark and the bitrate looks a bit choppy at times (barely noticeable , not much) this could be easily corrected by exposing slightly brighter (+1/3 or 2/3 stops) and maybe with a slightly slower shutter speed to smooth out the movement For the smoke cameras : yeah this one is a bit tricky because it's still noisy but now with the lights the smoke is clearly blown out, I don't know how much manual control you have on these cameras but you could solve the noise by reducing the ISO and diffusing more your lights (try avoiding shining the light directly on the subject but rather use bounced light on a ceiling/ a wall) this should look way better. Great video by the way these are all minor comments this show is still a joy to watch.

You got the name wrong on the smoke tests, the "Turbofan" was called "Captain Amerifan" ;)

These are really fun videos 👍

That music reminds me of Final Fantasy 7 when you’re on the tropical island, or at some resort, it’s been quite a few years

Hey guys I’m the maker of the “NOT A FAN.” I’m actually shocked that it didn’t thermal throttle! I also want to note that NAF backwards is FAN as a little Easter egg. I want to do the aero wheels next, but my CAD experience is just so limited that idk if I’ll be able to do it. Maybe we will see a NAF V2: Electric Boogaloo next season!

5:47 long range cus they are already fast enough. They dont need more performance.

Hey! I'm a fan

That fan was inspired by the fan clutch on the cooling fan.

Just had a thought. For a head to head fan showoff. 120mm tube 2 feet or so, with 6 inches of the center drilled. Put a plastic ball inside, and competing fans on either end. See who pushes the ball closer to the other. Kinda reverse tug if war.

Nice video. The Not A Fan, based on the Tesla wheel. You raised the question if they perhaps looked towards blowing cool air into the car body. This could very well be, because each wheel houses an electric motor, and any extra cooling would be welcome. {Note, I am saying this based on vaguelly remembered vids on electric motors and how they are made to go.] But I have been a fan of the fan showdown from season 1. Good videos, interesting topics. Major Hardware is a channel to recomend for giving your engineering side a bit of a tweek.

Oh, i had thought that the car desing oriented one was made thinking on the properller of a turbo

Captain Amerifan sounds like a Delta fan (delta makes very loud, unapologetic server fans that move tons of air)

The captain amerifan looked really, really cool. I wanted it to perform, but alas... Sooo, I'm a huge fan of the show, and I never miss an episode. I have no clue how to create stuff on CAD, but I am a musician. So I wrote a song specifically for the fan showdown. I sent it to you on your KZfaq email, but I'm sure you get a bazillion emails a day and it got flooded. I basically got inspired by the slow flow of smoke going in the fan. I'd give it to you for free, as I'm not in it for the money. I just thought it would be cool to have a non-generic song for your showdowns. Maybe one day, you'll stumble on one of my comments/mails? who knows? lol

9:22 - what a cool shot!!

Still here with my Drone blade showdown, 🤣🤣

With the Finger Killer, airplane propellers are basically spinning wings. The round leading edge should be what engages the air first. Also, when you have tandem propellers, the front will be less aggressive than the back. Part of the reason is because the front fan is grabbing more clean air and will be more efficient. Also, the air hitting the back propeller is travelling back already, therefore a higher angle of attack is needed to accelerate it even further. I am curious to see how well this fan would work flipped around. A side benefit will be that it should be quieter too. While flying RC planes, I can hear when someone puts a propeller on backwards.

Hey Major ! as far as I know, rims are designed to cool down brakes, and evacuate brake dust at the same time. Good rims at least. I'm not an expert though. Check F1 wheels, while braking you can see the brake dust evacuating, it's quite impressive.

Love guessing which ones will do best before seeing the results. I would love to see the season winners pitted against each other in a retest at the end of this season, alongside the A12x25. Since they are all going to be good results, it would be interesting to see how they stack up against each other when tested at the same time under identical conditions.

Not planning on getting a Tesla. Think I might get the Aptera Sol once it comes to market. Having the car basically power it's self one day to the next is definitely a huge selling point. Especially when the base model is only $25K with the fully speced out model at $45K. Way better deal than the Tesla. But if you ever need more than 2 seats in your car, guess it's not a good choice for you.

I would put the steeper blades on the bottom. Once the air is moving the steeper blades will accelerate it more, but the other way around the bottom blades slow it down.

Amerifan sounded special cause of the vibranium naturally.

You had the turbo fan in a pull config, my thought was they would push air onto the brakes by sucking air in that is parallel to the wheel, as opposed to perpendicular to the rotating wheel

Btw you labeled the captain amerafan twice on the smoke test. Love the content keep it up!

I think the reverse air foil idea might have been that it's the lower air pressure above the wing that helps a plane fly. So that negative pressure would in theory, suck more air into the fan. That's just my guess

I actually like the turbofan as either an extractor fan or for one of those coolers with fans parallel to the motherboard like stock coolers.

as a volkswagen audi enthusiast who ones several old rally cars. i love who ever came up with the turbo fan design.

If possible, you should see about tracking the Hz of the fans along with the Dbs. It would be interesting to compare the pitches that way.

You have the Captainamerifan title on the turbo fan too during the fog test

Been waiting for someone to do a Corvette Saw Blade. But, I'm happy with the Tesla wheel. New setup is coming along very nicely! I don't think you need to tweak anything too much, as it looks pretty good as it is. So, maybe a few very minor tweaks here and there, and you should be good to go.

I liked the choice of music this week

Most modern cars actually design aluminum alloy rims like a fan to cool your brakes and rotors. That's why vehicles with steel wheels generally wear through brake pads faster because they can't dissipate heat.

you can get a sound spectral analysis app for you phone peek sound frequencies can be found for each fan.

So many of the fans you get seem to have a lot of focus on the intake of air but very few seem to account for the downstream air flow shape. The ones that do seem to be at the top of your leader board.

This is my favorite non-educational series

The hubcap fan isn't just meant for brake cooling. It's also used to produce downforce by sucking air out from under the car. Most disc brakes have built in fins that cool the rotors fairly well. Depends on the design and use of the car.

The 60fps looks so good with the smoke

Try running a spectrum analyzer on the sound test. Some sound frequencies are easier to listen to than others, this would tell you exactly what is going on.

You have the text for the Captain Amerifan for the turbo fan during the smoke test.

@04:34 that kind of fan will work best in a centrifugal housing setup. Most waterpomp rotors exactly look like that. And yes Tesla had designed the rims as a fan, its something trending since electric vehicles, some use it for brake cooling and or earodynamics, some just go with the flow and think, we now need also fan rims.. lookit up, toyota and some other speak very open about their fan rim designs.

I think that finger killer might have done better with the shallow and steep segments switched. Also with the airfoil switch mentioned in the video.

Turbo spoil blade on printer blower fan? Is this possible I’ve got a voron afterburner and am wondering if it will make a difference preferably resin printed

I think the new camera doesn't make the cut. Last camera worked fine! and the visuals were delightful. But, to be honest. I don't know what I should see there? The turbulence suction? the dispersed flow? the radius of dispersion? I don't know.
