EVERYTHING you need to know to send your design to the Fan Showdown

[@3Dwesley]

I’ve been watching the series with great interest! Didn’t push myself enough to look further into submitting. Well now I have to.

[@RobertBarton86]

I'm really enjoying this series! One of the things I like about it is some of the really out of the box designs, that may not top the leaderboard, but still perform admirably well. Maybe it would be fun to add a poll for the "fan favorite fan" at the end of each season. Just a suggestion.

[@someonestolemyname]

If you include the ring dimension and the suggested clearance and tolerance, people may be able to submit more aggressive designs like the Extractor centrifugal fan in S2E5

[@theputnamto3468]

Also dimensions of the fan bracket would be nice

[@jaxonevax6135]

You are having so much fun with this series. Wonder what else you could do that would be this fun

[@jonw2945]

Am also a new fan, binging the past episodes, one of the people who had been modeling for multiple years but never tried enough to look into joining. Thanks for this video ♥️

[@danielsjoblom6359]

This is so interesting! I could rant forever about computer cooling, like, why arent the CPU on the other side of the Mobo, making it easy to cool with a passive heat sink? Fans are really interesting as well, especially since application makes huge difference in what fan works where. For a tight heat sink with lots of back pressure you would want a fan with a low angle of attack on the fan blades, as they "pump" air with more force. As an exit fan a large angle of the blade is better. Since most fans are variants of airplane propellers the new and different ones on this show are really interesting. Keep it up, love it!

[@MrMcGreed]

YES! I asked for this in a comment a little while a go! Thank you! Don't really care if I was the one inspiring this... it's just great to get the info!

[@Makinsson]

Could you print the exact same design as noctua fan to compare how 3d printing limit the performance of the fans? This would give us idea on how close we are to beating noctua fan :D

[@Dismythed]

He already did that and concluded that there was no appreciable difference. Though there is a little difference between acrylic and resin, with resin being better.

[@NarutoMagicCyclops]

@@Dismythed resin mostly reduced overall fan noise and had better print quality however the cooling factor didn't improve by much.

[@Dismythed]

@@NarutoMagicCyclops Indeed. He also came to the same conclusion about using acetone fumes to smooth out the surface.

[@billyw1345]

I really don't care about cooling, but holy crap I can't stop watching!

[@genau14zeichen]

I sent a design your way a few weeks ago :) I hope it fits the requirements! So hyped to see how it will perform

I wouldn't say I'm a fan, but I'm diffidently breezing through the videos with an Strong interest in Aero Dynamics :-D

[@shanyrayquaza3946]

If the size of the file is larger than what email supports, can they not put it on google drive then share it to the fan showdown email?

[@mattdumbrill8324]

I submitted something a while back, probably a bit janky on the 3D printing side tho. Keep up the good work, great series.

[@Volt64bolt]

Can you include how far apart the mounting holes are so that more complicated fans can be made?

[@xTheJiggyx]

​ @RytisM 120mm fan is the outside dimensions of the fan, the holes come in a little from there and are actually spaced 105mm apart

[@rytism7156]

@@xTheJiggyx Yes you're tottaly right. My bad

[@williamplatt1680]

Really the only thing I was curious about were the dimensions for the motor hub where the fan pushes on, and now I know.

[@koorite.]

How do you get the preview of the .stl file in windows shown around the 4:30 mark?

[@luke_fabis]

You need at least Windows 10, following the content creator update from a few years ago. If you enable the preview panel in Explorer, STLs should be viewable.

[@routtookc8064]

To clarify, when looking at the inlet side of the fan, the rotation is counter clockwise?

[@Jose-Sousa]

I sent mine at 6th August 2020, spec wise I followed the stuff in the thingverse, I made it in OpenSCAD, is that an issue? Yet another question would be if you contact the sender upon finding some solvable issue? It would be nice to have some feedback over the rejected fans and the reasoning... And ... I noticed my submission had the .scad with 0 bytes and just now I went ahead and inspected the STL file just to find a few issues due to corruption. I probably uploaded it to the email before the file was finished saving... damn ... D: Well I've replied to my own email with the correction, oh well... If it gets picked I hope at least you get the correct version...

[@robertmoore119]

I think I'll create an entry to send to the fan showdown. I want to start my own PC part platform, at the moment, I have some designs in progress, but I can't yet start the rapid prototyping process. Seeing what on of my designs might do would be interesting. Of course the showdown is a competition, so one of my designs may not even get chosen. I'll see what happens. I have not been to college for engineering, so my designs are from knowledge I have collected elsewhere.

[@lampajoo]

What are the specs for the power supply and motor controller used in the test?

[@kanokwanphuawongphat1021]

If I use a tall blade with a extended shroud will that work?

[@NovaDragon]

I am a big fan of this showdown!

[@jamescarlgonzales2789]

[@VagabondTE]

What are the hole dimensions for a shroud?

[@Trekeyus]

Would be fun to try and build a Contra rotating fan but I don't think I could build the gear system in such a way that would work efficiently.

[@alexmipego]

I've an idea, have you ever heard of starlite? It was/is a material with extreme heat resistance, and it's famous for its interesting story. In short, the recipe is lost, but I've seen some diy attempts that almost replicate it. One of the characteristics of the material is that if you apply heat on a side, it (almost) completely protects the other side - a common demo for it is using a blowtorch on a egg protected by it, and the egg survives uncooked. Anyway, what would happen if you coated the blades of a good (maybe even a bad) fan? In theory, it would rather limit the heat to one side of the fan, thus making sure the air being blown should be cooler than it normally is. If the concept and the material works, it might work well to "direct" heat where we want.

[@loganthomas5043]

An idea just came to me, what if you were to turn the fans around for every time you check the cooling. To see how it will perform both blowing and pulling air.

[@ghomerhust]

me likey

[@d3lsl0w]

Pushing air through the cooler fins is always more efficient, unless you can ensure an air tight fit. You can direct air through the fins with less leak loss than you can pull through fins. Air will come from wherever and not through the fins.

[@andrewyoung4473]

@@d3lsl0w but different fans will perform better or worse comparatively.

[@TAB_100]

could you maybe make a video showing how to create a fan? (if you haven't done one yet)

[@raymonddegennaro3097]

Can the spreadsheet with the compiled results be downloaded?

[@brucebaxter6923]

Can we please have a comparison between suck and blow with the standard fan please? Since the blade tips move most air they do most cooling on blow, while suck is far more evenly because the momentum vs resistance is not as uneven.

[@Korn_Flaek]

need help on getting recommendations for a program to make a fan

[@nickaww]

Is it possible to make the fan in an other program and then make it an stl? Referring to 3ds max

[@Thesupperals]

What about the fan casing's innards? I've been thinking about those kind of ideas that would improve the capabilities of a fan's centrifugal force, speed, flow of air and noise reduction.

[@slazds]

And if somebody e-mails You his google drive link (if the .stl file is bigger than e-mail sending allows) with the file in it. Will You use the link and download?

[@draggonhedd]

Oops. I fixed the model I submitted a couple weeks ago and replied to my original email with the new STL. I hope you decide to run it, I would love to see how it holds up as a "serious" attempt.

[@PokeAmp]

ok im noob at this modeling thing can i just draw it and someone make it ?

[@johnsherby9130]

You were talking about making this video while you were on stream!

[@GeneralNickles]

I submitted a fan a while back, and I genuinely have no idea if I got any of the dimensions right. To be completely honest, I don't even know how to check if I got it right. Fusion 360 has a serious learning curve, and that was the first (and so far only) thing I ever modelled.

[@micahjensen7407]

It would be really cool to see you put some fans on the market through the tests that you do on the show.

[@davicorosello1588]

And i think it could be a good idea to send you a screen capture of the fan model to your mail, so you can see it in advance and do a quick visual selection.

[@caincha]

Suggestion: how about sharing the files of the fans shown in the videos? I mean sometimes I see a fan that doesn't perform all that well and I think 'well it would work if such and such' and instead of just saying it in the comments I could download the files and work my improvements then send it back. Obviously some people will just send copies barely different but you might get some good stuff from there - plus it would make it easier to get more submissions :)

[@aspenmallery]

I remember someone mentioned awhile back that there was a website in development specifically for this series/contest. Is there any update on that??

[@hurlah]

Is there a link to the fan leaderboard?

[@FlashDrive356]

[@Dartace2ace]

Real quick question. I use blender most of the time, do blender designed stl files work well here? (For instance for my 3d printer, i need to scale my models by 1000 times to get the right size)

[@johneppstv]

Can I do it in blender? I just did the donut tutorial so it would be a fun thing to try.

[@bluephreakr]

[@deathpony698]

Looks like I submitted mine correctly like a month ago, still hoping for it to get picked!

[@kashv1793]

Same is the case with mine as well.

[@lansonfloyd4687]

I've been watching this showdown for a while (thanks, youtube algorithims) but one thing I think is being lost here is how certain fans do with certain amounts of static pressure, and related to that the other issue I see is that the fan is run open on both sides for the smoke tests. This means the pressure is equal on both sides of the fan, other than what the fan has going on in its immediate vicinity. It would be interesting to see these designs running in maybe a plexi box to simulate a case, and/or through a modified Mass Air Flow sensor to determine true air flow rate at a given pressure. The radiator cooling Delta measurement is useful as is the sound reading though.

[@bepstein111]

sorry if i missed it, but what print settings do you use for fans? That can really change the design process.

[@stevengotthardt9299]

It would be swell if you could acknowledge submissions. A bonus would be if you could indicate if they were printable. ;) Thanks.
