Nice job dude!

I've been thinking about doing exactly the same thing since he announced the new season. should've gotten on it sooner

Nice work, I would love to play with one of those, is the design available anywhere?

I watch the video, read comments and I don't get it. How is The Wonder From Downunder possibly a PC fan? I feel like there should be boundaries to what dimensions are allowed. If you use as much volume as The Wonder From Downunder, then you could use 2 regular pc fans as well and cool much more.

​@@Platypus_Warrior this is a static pressure design challenge. It was never meant to cool a PC.

Here's to the first person to submit a piston based compressor "fan"

@@ramb4ldi lol

3d printed air compressor go brrrr

I hope! Imagine pumping a tire with an A12X25.

PD pump go brrrr

A car turbocharger

@@ahmadrizqiramadhan7846 slap on a blow off and it would make stututuuu..

i was gonna say, this isnt a Cmaj, its just like a coir singing the C note in various octaves, which is still cool.

Yep, and in this the C3, E3 and G3 peaks at ~131hz, 165hz and 196hz can be seen on the frequency graph :3

Imagine connecting that to tubes of different lengths; it's essentially a new musical instrument controlled by RPM.

Also it's only gonna be C if it spins at the right RPM. Else it'll be some other major chord with a different fundamental.

@@mhoop1 I could swear there's some kind of instrument that works like that, kinda.

He really thought outside the box

Also, It's pronounced "Steven" NOT Stephan/Steffen/Stefan

Wee way to go from f1 needs variable geometry and secondary channel to increase entrainment then we'd be talking f1 more group b tech also a tiny hole from pressure side to behind wheel to balance static pressure so it runs free under variable air pressure loads :).

@@Tom-yc8jv definitely depends where you’re from a know a Stefan from Europe that’s pronounced stef-ann

@@Tom-yc8jv STEPAAAAAAAN

A fan not tested yet

I see what you did there

I thought so too!

It seemed to produce the most uniform airflow.

@EMILE12345678901 - Could it be that the airflow was being organized into vortices, as described by the theories of Viktor Schauberger

@@brandonroeder2461 - it looks as if the flow could be focused into a reducing helix with a slightly different design. I wonder if chatgpt can analyse video frames for fluid dynamics yet?

@@christopherd.winnan8701 I don't think it can, but fusion360 and solidworks can afaik

He shoulda overlayed a "C" chord from a guitar next to the fan sound...this way us non-musically inclined "deaf as a post" folks would understand It did sound pretty nice...not the high pitch whine of high performance fans, but a low hum

@@haydenc2742 A pipe organ would be the closest match to the sound characteristics of the fan, that 'breathy' sound. You would want the organ notes to be played very lightly, to match the soft fan, as closely as possible. If you find a single note played on an organ and listen to it while you think about, and try to recall the sound of the 'C-Major' fan, your ears will probably notice some relative similarity in tone and feel.

@@haydenc2742 Guitar works fine. Search "c chord" in youtube and find the 45 second video with "C Major" in the thumbnale. Now go to :36 seconds in the C Major video and 7:35 in this video and hit play on both. TADA! it sounds pretty cool

@@haydenc2742 Guitar works fine lol. Search c chord in youtube and find the 45 second video with "C Major" in the thumbnail. Go 38 seconds in and pause. Now go to 7:44 in this video and pause it. Now hit play on both. TADA! pretty cool right?

@@haydenc2742 Guitar works fine lol. Find a C chord video on youtube and play it along with the fan at 7 minutes and 44 seconds on this video. (My comments keep getting deleted. I think it's because of the time stamps. pretty annoying)

Paradigmatical from down under.

You're welcome !

I saw the same video lol!

They've been using fans for a long time. If you look up air raid sirens you'll find some historical ones. These designs are many times more effective than speakers of equivalent size in emergency alert systems.

​@@Varadiio I have a small 12v version of those that was designed for car type applications, and they're so neat. I want a large one, like an original. My neighbors would love me.

@@goosenotmaverick1156 where can i get one of what you have

@@pjbklk the mini air raid siren? I'm not entirely sure, I bought a box of old car horns and it was the only modern thing in there. I will indeed go take a look when I get a chance and turn it on and annoy the neighbors, as well as look at the brand or any identifying marks on it to help you out.

need a cheater v. wonder just for grins at this point

​@@Billys3Dit would probably lose against the cheater.

I am the designer of TWFD. I came up with a design to go up against the cheater but it didn't get picked. It was at least equal to it

Total side comment, i saw you write TWFD, and I was"what is that? " lol, never knew down under was one word, and wouldn't have included" from"! (TWDU) Damn, chatting with people from around the world is fn cool! And a damn clever fan!

@@TheRattleSnake3145 Depends on metric - I could see the Cheater losing on pure static pressure, as an example.

@seth6118 Small clarification; you can't just divide the frequencies between 440Hz and 880Hz evenly into 12 notes. Since the octave is an exponential scale, you have to use a logarithmic division where the frequency of each note = the frequency of the previous note * the 12th root of 2. That mathematical ideal is then usually tweaked by hand to make some chords a little more pleasing to the ear. You can google "musical temperament" for more details.

More like "Hold my truck full of bear."

I think i may have altered the designs for static pressure comps in thw future.

I like that idea. I think, if you add a pan of water to the heater, rest it on top of the radiator, or a wet towel, the evaporation will cool the radiator and force the heater to work harder.

No, they you're introducing error from ambient temperature and humidity (higher humidity is higher thermal mass in the air) and all sorts of other things I can't think of. Interesting idea.

pretty much what's been covered by earlier seasons when they actually cooled a cpu

It was a chord. C E G. the 4th 5th and 6th harmonics of C.

@@Endrushmi But it wasn't C E G. It was C C C. It is still a chord but it's a chord of octaves. But it's not C major, I'm assuming that's what he meant to say.

@@J.PC.Designs The C3, E3 and G3 peaks ~131hz, 165hz and 196hz can be seen on the frequency graph...

@@J.PC.Designs It was definitely C-E-G, the explanation just wasn't fully on point.

Thanks!

Yup. I would also like to see how good/bad it actually is at cooling.

Thankyou!

Decimate-transitive verb 1 : to select by lot and kill every tenth man decimate a regiment

@fully_retractable - Plus, there seemed to be some serious pattern formation in the outflow. Some kind of venturi vortex maybe?

More airflow means less static pressure. It's a square function so you can't get both. Kind of defeats the point.

I want to understand this so bad!

vacuum cleaner you say?????

@@johnthegiant320: You're not sure you can read that well, or...?

@@HelloKittyFanMan this almost is, but a vacuum motor and casing sure does move a lot of air.

@@johnthegiant320: No, it isn't the motor that moves the air. And a vacuum cleaner _fan_ may not move a lot of air at once; it might just move somewhat of a little quickly (which still might not be a lot for a while). Yeah, I know this is kind of like a vacuum cleaner fan, but it still isn't one just yet.

@@HelloKittyFanMan was just saying it's an interesting starting point for a possible idea.

I didnt use any apps, just did what I thought would work.

haha the one that makes you poo!

Are you sure about the major6 ratio? It should not the same as the major3

@@Bleaksigilkeep you’re absolutely right! Corrected. Thanks!

From Corsair's website; "When you think about cooling, you often imagine air flowing over hot components, instantly cooling them. However, PC cases today are packed with obstacles in the air's path-from AIO radiators to the dense fins of your CPU cooler. This is where static pressure steps in, powering through these impeding components to maintain airflow and keep your system cool. High static pressure fans are essential for components that rely on a steady flow of air through dense fins for cooling, such as water cooling radiators and heat sinks." Basically, it allows the air to move through tight spaces. It is extremely important in small/tight cases where you barely have enough room to build in.

I think we are long past PC cooling... I think it's fun.

@The_Keeper in tight spaces forcing air through is important. I've never seen the inside of desk top computer that was so packed pressure was needed. I could see it in a laptop or if you had it hooked up directly to a radiator. Even then radiator is pretty free flowing for the the size of the fan being used.

@@SG-Cichlids Look up some ITX cases. Some them can barely fit the components. Thats where a decent static pressure is more or less a must to get air to not only the CPU and GPU, but also the VRM and RAM, especially considering most of those builds are watercooled and won't be passively blowing air over them. To be fair though, the static pressure in most builds are a very secondary concern. You just need *some* pressure, not a small hurricane as some people tend to think. Espacially if you're not running a positive pressure build.

Static pressure is what carries away heat. If the pressure in direct contact with the radiator fins (the static pressure,or SP) is higher than the surrounding air, it will distribute the heat better, thus carrying away more heat. The Wonder from Down Under is increasing the incoming pressure, which draws heat away as it expands into the lower pressure of the surrounding air. Refrigerators operate on a similar principle by compressing and condensing a coolant that carries heat away, boiling or otherwise expanding, and radiating the heat away through the fins. In cars, liquid cooled computers, and a lot of other devices, the coolant doesn't need to boil or expand, but the radiator slows the air being drawn through it by the fan, and thus is reducing the air pressure on the fan side. In a car, the increased static pressure on the side opposite the fan comes from the forward movement of the car. The increased pressure gives the radiator more molecules to pass the heat energy to, which then dissipates said energy on the other side as it passes through the fan. Since desktop computers don't generally move at a speed that provides enough SP to sufficiently cool the PC, TWfDU provides that pressure. If a fan is drawing air through the fan, the SP of the surrounding air is then higher than the SP inside the fins of the heatsink. This is, of course, reversed when the air is pushed through the radiator/heatsink. Pushed air gets its SP from the fan and housing. Pulled air gets the SP from the surrounding air. The latter usually gives more control over the SP differential, but both work on the same principle. Focusing on the SP, whether increasing or decreasing it, is what has the greatest effect on a Fan's efficiency.
