I really loved the organic appearance of your design. If I had money, built pcs, and had a 3d printer I'd definetly try to make a build around it personally.
Dude, I designed the ceiling fan, and you have no idea how pumped I am to make it into this episode! Thanks so much, you really made my week! Great job on the print too, much better than my test print lol
@@danieljenkins4213 Thank you! I modelled it entirely in Blender. I tried it with 6 blades originally, but that just wound up ruining the look IMO. But yeah, more blades would almost certainly make it work better!
I have a theory. A theory that states tip speed determines air intake. I need a stack of edge intakes attached to ductwork to drag air into the core, and feed that air to the fan hub. While remaining balanced Tricky. But should be possible.
Ok, hear me out: make a website that's like a leaderboard and album at the same time. Maybe contact Wix or Squarespace to check if they're willing to sponsor that. The amount of fans you tested got reeeeally big, so it'd be nice to have a place to reference past designs. The site should have pictures at least, but if you managed to make a 5s smoke test clip there (with actual sound), it'd be soooo cool
You're really getting into your groove now! Quality improving, presentation is polished and new tweaks are quietly being tested in every episode. Some well deserved recognition for the work you put in doing these videos. Well done!
it would be interesting to see it in a case, but just wondering if it would fit behind the Front Panel as it does stick out quite a bit from the front of the Frame
As a season finale (eventually) it would be awesome if you re-ran the top 4 + the noctua in a direct head to head, just to prove that the results are repeatable.
top 10 even would be awesome, I just noticed an interesting trend in the cfl numbers and realized that to get an accurate reading there probably needs to be a tube on the output side of the fan to make sure the air flow stays cylindrical. curious to see how those numbers would differ even though the delta wouldn't change.
When I first saw this I was hoping that someday he'd be able to take the top fan designs to Noctua to have them made in a proper facility, let their engineers make some optimizations and make a set of 4 fans for each of the top winners. When these blades beat their designs there is no way Noctua didn't take notice.
yea I thought it was a nice addition as well. Now he just needs to change the way he announces and displays the temp results so it's not just completely random. Maybe actually announce them in order? or put them in order on the screen? Do *something* man cuz it's always confusing af.
It's awesome, not just consumerism infomercials (linus tech tips), but creative and viewer participation. The playful competitiveness is very entertaining. Can't help but think; what really is the optimal fan design?
The fan designers should tell in their submit if they allow the fan design for download, that way Major could just add a link to the description for download 🤔
@@ragetist I think thingiverse/prusaprinter/mmf would be much better, at the very least the design will be under CC/GPL protection. If the model would be just "downloadable" I bet my head someone will soon start selling them ahahahah
Can't because my ship post actually made it and it's on thumbnail XD. I was expecting it to spin quite a bit faster. As a space nerd I gotta point out that the rocket at 4:14 is the Chinese LongMarch-2F rocket, not the Soyuz tho.
I sent a Batman style fan design a few months back, haven't see it yet, although I'm sure you have hundreds, if not thousands, of fan designs. I hope you ended up getting it, and it didn't go to spam.
@@JohnyBoat.JZ610 it was more of a bat-a-rang style, pretty simple, but I thought it would be cool. :) I called it the batfan (see what I did there) ;p.... I'll see myself out.
@@JohnyBoat.JZ610 I didn't either. Lol took me like 1/2 hour to do though. (Already had minimal CAD practice) made 1 fan blade and hub, then multiplied the blade by 8 or 9 and spun them around the hub.
I submitted a tesla turbine style one last week. I don't expect it to ever be printed but it was nice to learn openscad with, so I'm ok with it just hanging out on thingiverse for passers by lol.
Great addition of the spinning display of the fan in the lower left-hand corner for the airflow tests! Your production quality on this series continues to improve!
The slug and the demon fan designs looked to be high static pressure fans, and probably contributed to their good scores, and the homespun was characteristically a high CFM fan.
That Slug fan had the most pleasing sound, to my ears. I am rather sensitive to high pitched sounds. Many of these fans have felt like dog whistles, but this fan was soothing.
I love the ideas from all the fans in these series! I am always keeping my eyes out for a design I really like that performs pretty well to spice up a build
I enjoyed this episode! Great selection of fans. I wouldn't have been surprised if any of them had made it on the board. Somebody is going to come up with a fan design like never before.
*@Major Hardware* In the smoke tests, I see a lot of smoke goes around the fan, maybe it is better to mount the fan-frame onto an acrylic sheet that acts as a see-through wall?
I love the fans in the last couple episodes, these are so much cooler than the fan I made. I have no idea how they managed to get so much detail into their builds when fusion 360 was fighting me just to make thicker pieces and fillet.
Would be nice to see noise-normalised testing. I think the slug would've won in that regard. With those huge flaps it could move a lot of air even on lower rpm-s.
@@redstarwarrior85 i had assumed you meant to put the entire fan in a duct made of plexiglass essentially. That would have it's own experimental value, though not much value in regards to the intended application. Well maybe to test the static pressure generated by each design but I digress. Any way, my bad.
Really liked how much air the Slug one pushed. In the smoke test it looks like a winner to me even though it did not make the Top 5 I'm sure it would cool nearby components just as well as it cools the CPU heatsink. And that GridFin should not have worked lol I mean come on the fins should have pushed the air outwards and yet the smoke test was very good - how can that be?! 😂😂
I suspect it is the angle of the actual material faces that are directing the air through not the greater blades (as the leading edge is so broad, and there's no actual wing to direct the flow). If that's the case some adjustment would likely significantly improve the flow. But if it's some weird pressure differential thing, It may be designed perfectly??
Dude, with all do respect.. I Like ur show. been watching since the beginning and love it still love it. But I Liked you, because you were like youtubers in the beginning. But now sometimes you feel like being a influencer. Don't change, keep it real!
I was kinda hoping that the blue vase thingy was one of the fans :p Nice format with the side-view smoke test as well, very interesting to see the air flow clearly. And nice touch with the holy water :D Great video as always!
UA-cam keeps insisting that I need to see these videos and it's blowing my mind that you just keep making more and more and more of them. Seriously guys, this is like watching a bunch of accountants trying to make a trebuchet out of pens and rubber bands. Go to school and study. It's not that hard. We've invented this thing called "Science" - it's like a magical power that lets you get things right the first time without having to guess and check.
Y'know...looking back at the sound levels of the top-5, I wonder if the Slug wins in terms of cooling-per-dB. The swag technically has a lower dB, but listening to them, the tone of the Slug is lower and less intrusive. I don't know if it's having the fins extend all the way to the middle or what, but some element of that design is doing work.
It’d be kinda cool to see how well the fans push (or pull) air through a radiator or heat sink fins with the smoke machine. This series is pretty awesome.
I think the crowdsourcing DNA of this series is fascinating and can be expanded into other industries. For example wind turbine propellor designs. I think the big brains within this community can also expand on this idea.
I actually thought the slug fan was pretty cool, and the noise and thermal performance wasn't half bad either. Obviously the demon fan scores serious metal points, but I think the slug impressed me more just through how functional it was despite the unconventional design. Also, did you ever hear about whether the acceleron fan from S1 was going to be produced? It'd be cool to have updates on the first potential commercial success story from this series.
“Can grid fins make into a fan?” Me and BA in aerospace engineering: Nah, they make them to create drag. “Let’s make it into a fad!” Me: *surprised Pikachu face*
In the missile world grid fins are used as steering surfaces and they handle high supersonic speeds well. It's the transonic region that kills performance as they form a detached bow shock.
I've definitely seen a hot ceiling. Felt it too. In an apartment I lived in, with black tar shingles on the roof, and zero attic ventilation. You could not touch it. The air conditioning bill was insane.
I was really impressed by how smooth and mellow the Demon sounded. Possibly due to the "talon's" effect on airflow? And I thought of something that it seems you already tested, so I'm off to watch some more of your videos . . ..
I submitted a fan design to the email shown in "how to get on fanshowdown" video or whatever its called, when should I expect to possibly see it on an episode? I'm dying to see how well I did :)
The grid fin, just like so many others that come in last place, it just fills the room with smoke, flings it everywhere. The slug actually surprised me though, it looked like it was doing the same but was really pushing it all just in a wide pattern. The Homespun was the one I was rooting for, such a smart idea maybe longer blades would have helped. The Demon was actually similar to an idea I had after seeing the moose one from last week. Guess I don't have to try it now!
I don't know if it's been mentioned before, but a question I was wondering about is the frequency of the sound made by the fan, to go along with the dB level they get to? The different tones have different levels of comfort possible depending on how the ear registers the sound.
really love your videos buti sometimes wonder, is there a reason why you very rarely print fans in resin? in terms of time and ease of use wouldnt it be faster in certain cases?
The blow pattern of the ceiling fan is super interesting! It looks like it's directing air towards the center, which tends to be a 'dead zone' for most fans! ...or maybe that's just how it looks since the blades are smaller...
The grid looks like it would have interesting applications. The exhaust is so spread, it seems like it would be better drawing air into a case or across a large set of components in a narrow area.
Still think you should build a fake "case" out of for the smoke test to prevent smoke going round the outside and rejoining the outflow stream. I recommend a black perspex sheet opposite the camera for contrast, and clear perspex for the two sides the cameras look through.
I guess the slug moves so much air because it has a large surface area on the blades, meaning it can move a lot of air at once, plus the sheer volume of the fan makes it so that it has a larger area of capture than most other fans, so it isn't exactly the best fan, but it's pretty damn good for a non-flat fan.
It should be noted that the fans ability to compress the air is important. when a pc fan is mounted on a case, the fan needs to force the air into the case and faces resistance. Many pc fans fail in that they do a good job of moving air only when there is little back pressure. I don't have the skills to design a model but maybe a fan that shares a shape similar to a centrifugal compressor would help in pushing against the backpressure.
I think the biggest issue with the grid fin is that the angle is excessively steep. If it looks shallow, you're thinking 90 degrees out of phase -- the large fin structures may look superficially like blades, but they are not actually blades: it's the gridlines that are the actual blades. And because the grid-blades are perpendicular to the fins, a shallow angle for the fins means a steep angle for the actual blades. If you adjust the angle to try to get the grid fins working, the fins will end up being so narrow that you're going to struggle to make a useful number of grid-blades through them.
My fan made it on woo, go slug go!
all hail slug, the fan that just leaves a trail through all the others! eh? leaves a trail, because slugs...I'll get my coat.
Great job on that design! I honestly think it looks amazing. It's almost alien. Love it!
@@Lk95rulez Thanks mate. I made it with fusion 360 soft bodies.

I can visualize a PC mod that looks like a little house with these for the fans and little chandeliers in it for the lighting... Very cool fan man.
@@megaglowz8540 Windows 10 home edition? :P Thank you!
I loved seeing this one! Couple of things I'm curious about: Did you use F360 for this? Also, would something like 7 blades pull more air I wonder?
@@danieljenkins4213 Thank you! I modelled it entirely in Blender. I tried it with 6 blades originally, but that just wound up ruining the look IMO. But yeah, more blades would almost certainly make it work better!
Your fan made me smile. The idea of it is brilliant.
I kept waiting for him to announce the blue vase was actually a fan XD
Thanks for the idea!, may just look at designing a vase mode vase fan!
Feels!
Me too!
I have a theory. A theory that states tip speed determines air intake.
I need a stack of edge intakes attached to ductwork to drag air into the core, and feed that air to the fan hub.
While remaining balanced
Tricky. But should be possible.
me too, the first time I saw it in a video lol

Agreed
How about site where we can also download the files
@@635574 yes please!
I'll sponsor this.
You should put the noise level of the fans into the spreadsheets. It's relevant information, after all.
In that case the fan noise while mounted on the heat sink would also be interesting, as the reduced airflow certainly also changes how the fan sounds.
I said that several episodes ago
He had problems with that, so it'd be meaningless.
...what?
You're really getting into your groove now!
Quality improving, presentation is polished and new tweaks are quietly being tested in every episode.
Some well deserved recognition for the work you put in doing these videos.
Well done!
Now the Slug had a pretty interesting exhaust pattern.
I honestly thought it was going to be the worst since it looked like it was just throwing it everywhere but straight back.
It actually looks pretty good for front intake fans
it would be interesting to see it in a case, but just wondering if it would fit behind the Front Panel as it does stick out quite a bit from the front of the Frame
@@Erteywie except it would have to be Mounted on the outside of the case since it stick out past the frame of the fan.
@@shaneeslick it would be viable for my case, as the front panel has been removed already due to rad size and how badly the panel restricted airflow
As a season finale (eventually) it would be awesome if you re-ran the top 4 + the noctua in a direct head to head, just to prove that the results are repeatable.
top 10 even would be awesome, I just noticed an interesting trend in the cfl numbers and realized that to get an accurate reading there probably needs to be a tube on the output side of the fan to make sure the air flow stays cylindrical. curious to see how those numbers would differ even though the delta wouldn't change.
Yeah that would be Awesome to have them all tested on the same day 😁
When I first saw this I was hoping that someday he'd be able to take the top fan designs to Noctua to have them made in a proper facility, let their engineers make some optimizations and make a set of 4 fans for each of the top winners. When these blades beat their designs there is no way Noctua didn't take notice.
@@orangeapples the problem with this is that specifically the ones on thingaverse he doesnt hold the copyright to
Season by Season head to head Top 4 of season 1 Vs season 2 or any that beat the noctua as the Noctua Killers.

It’s a shame that we can’t even get these designs despite him hyping up the idea of making a themed build.

slug is so cool, would love more of such stuff
Best showdown video so far. No movement in pushing the tech forward. Big on fun. Many laughs.
The slug and the demon fan designs looked to be high static pressure fans, and probably contributed to their good scores, and the homespun was characteristically a high CFM fan.
I knew that Slug design fan would peform rly well. I think that a lil bit more tweeking the design and it might come on top

Omgg, it's been a while since I saw the series but omg the flow vis test has become AMAZING. Great job man keep going
5:06 why does the fan noise sound dampened after one second, for all fans?
youtube audio processing?
Whoa! The Slug was one off from making it on the board. Was it solid fill? Maybe it could do better not being solid fill, I wonder?
*@Major Hardware*
In the smoke tests, I see a lot of smoke goes around the fan, maybe it is better to mount the fan-frame onto an acrylic sheet that acts as a see-through wall?
like a wind tunnel with just the fan moving the air
I was thinking stuffing the smoke tube full of drinking straws to encourage laminar flow, so it doesn't billow all over the place.
This was probably the best overall selections I've seen on the show.
Loved the jokes and the fun vibe. And the slug did top 10. So there is that.
I love the fans in the last couple episodes, these are so much cooler than the fan I made. I have no idea how they managed to get so much detail into their builds when fusion 360 was fighting me just to make thicker pieces and fillet.

Would be nice to see noise-normalised testing. I think the slug would've won in that regard. With those huge flaps it could move a lot of air even on lower rpm-s.
That vase has potential
You should mount the casing to a plexiglass plate for the smoke test so we can see what’s actually being moved through the fan more clearly.
This is a great idea!
Maybe on the exhaust side of the fan. Seeing how wide of an area the fan will pull from on the front side is useful information.

Is it just me, or are his jokes getting better and better each episode?
Now I wanna see someone design the loudest possible fan.
Still think you should build a fake "case" out of for the smoke test to prevent smoke going round the outside and rejoining the outflow stream.
I recommend a black perspex sheet opposite the camera for contrast, and clear perspex for the two sides the cameras look through.
I guess the slug moves so much air because it has a large surface area on the blades, meaning it can move a lot of air at once, plus the sheer volume of the fan makes it so that it has a larger area of capture than most other fans, so it isn't exactly the best fan, but it's pretty damn good for a non-flat fan.
I think the demon would be worthy of a resin version. Just for looks of course.
A 200mm version of the demon would look sick!
It should be noted that the fans ability to compress the air is important. when a pc fan is mounted on a case, the fan needs to force the air into the case and faces resistance. Many pc fans fail in that they do a good job of moving air only when there is little back pressure. I don't have the skills to design a model but maybe a fan that shares a shape similar to a centrifugal compressor would help in pushing against the backpressure.
I think the biggest issue with the grid fin is that the angle is excessively steep. If it looks shallow, you're thinking 90 degrees out of phase -- the large fin structures may look superficially like blades, but they are not actually blades: it's the gridlines that are the actual blades. And because the grid-blades are perpendicular to the fins, a shallow angle for the fins means a steep angle for the actual blades.
If you adjust the angle to try to get the grid fins working, the fins will end up being so narrow that you're going to struggle to make a useful number of grid-blades through them.
