- I know I have been going hot and heavy on the fan showdown videos, but you all seem to like them and I love making them. Make sure to get subscribed and if you want to be on the show, make sure to head to my thingiverse account to see the specifications and then submit your design to the fan show down email account.

"If you're getting sick of all the fan videos..."
Woah woah woah. Let me stop you right there. The fan videos are the reason I came here. The reason I continue to stay. But your content as a whole is spectacular. No need to apologize.
some fans of him (no pun intended) are already here before the fan stuffs~ he's referring to them
Same, I'm here for the fans :)
Same here man
Making fan designs that may be able to knock out noctua at a cheap price is why I'm here hahaha
yep thats also my reason to subscribe
also thats why i never or rarely watch any contents in this chann
Agreed - I love this series. It's cool seeing what everyone comes up with.
Should have a special episode with a stronger motors that can run fans like that compressor at higher rpms!
A multilayer fan with gearing would be interesting, too. Somebody design one xD
Oh i would like to see this
that would have so much friction though lmao
I've really considered a fan with the gearing, but it would be relatively difficult to make happen since the durability of 3D printed parts isn't the greatest. Then you run into the same issue here that the motor just doesn't have enough oomph to run it at competitive speeds
Possibly engineering a shroud just to run all the fans at an equal rpm would be cool. We could see noise normalised, rpm normalised, and thermal delta normalised performance numbers.
Yeah, I would at least be interested in a same RPM performance comparison with some of the other blades just to see what the outcome would be.
Try the duct with one of the fans of the leaderboard! I would like to know if the leaderboardfan would perform better...
Since it goes inside the frame I’d wonder if they would have enough clearance.
Yesss
@@scuba535 Maybe someone can design a duct that fits to the front of the fan instead of internal. Should work with most of the fans, even the stock one.
I would very much like to see this
@@roboman2444 i was wondering that while looking at the video :)
LOL You know, you could rename the "Fan Show Down" list to "Only Fans" and get a LOT more viewers ... for some odd reason. :P
Nah, just needs to make a literal only fans account and just profit.
I agree, nothing beats a contest with lots of fanfare.
Sir, you won the internet that day :D
I would definetly check out his only fans.
The new series, i mean, of course....
yeah... that...
Fan's fans
"Are you tired of the fan videos?"
Nah I'm a fan of them.
matthew neal nice
Yucka yucka yucka
Fan videos get me all turbocharged!
You blew me away with that comment!
GET. OUT.
This jet engine fan is the coolest thing I've seen in some time.
It may actually be worth attaching some crazy motor to it to see what it can do. If it isn't a HUGE pain in the butt. 😁
Yeah, attaching a crazy motor will be awesome
Yeah! I want to see how it does at 2000 RPMs! Also, maybe mount a ball bearing on the front first to stabilize it
I was wondering how the performance would be if the fan was in a vertical upwards or downward configuration. With less twisting force, in the horizontal configuration in the video, maybe it will help before going all out?
It definitely needs more rippums!
Please give it more rippums!
It could even be driven from the front, while keeping the whole rear assembly intact - just unplug the back motor to avoid inducing current.
I love how this series progressed from "Let's print some fans" to owning a fog machine, resin printer, doing decibel testing and being a middleman in selling user fan designs to companies :D
Did they find the guy with the pikachu tail fan then?
@@michaelsorensen7567 I don't know, I hope so :)
@@michaelsorensen7567 They did.
@@michaelsorensen7567 Pikachu-tail fan!
XD
Now I can't unsee.
@@observingrogue7652 to be fair I didn't come up with it, I think comments on the original vid did.
But yeah, made me happy 😁
I feel like a tier list should also be made for the quietest fans.
I'm going to submit a bladeless fan and get number 1!
@@cncgeneral masive heatsinks everywhere
So long as there's a performance standard, that would be cool. Maybe a tier w/ best performance to noise ratio?
... the quietest fans that don't throttle.
69 likes, we'll leave it there
whenever you finish this series you should try and improve the top 5 fans with mod. like ducts,smoothing etc :P
Would love to see that I agree.☝️
He can't finish. There is more work to do
I agree. Never thought fans would be so interesting
@@tj71520 Yeah. I agree. I'm a big fan.
The turbofan compressor has false Bladeangels. They should be the other way around. Lot of potential missed right there.
Also it's really not well centered so a lot of energy is wasted on wobbling. Putting a shaft and bearings would make it a real deal.
I was about to say the same thing. Looks like he put both of them in backwards.
Yep, the stators were assembled backwards. Would like to see it the other way around.
@@AlitaGunm99 It wasn't an assembly issue, the stators had part of the angle on their outer loop and can only be installed one way. They were just designed backwards. I bet flipping the part file for the 2 stators is pretty simple for a second run though.
@@matthewmccarthy9283 While the design concept is complex and pretty it ignores the entire original benefit design of turbojets. In the fact the turbojet is moving at high velocity producing a ram air effect into the intake. As velocity of the vehicle increases the efficiency of the turbojet increases. In the context of current usage of PC cooling it just adds excessive rotating mass with minimal benefit for justification.
I enjoy the fan content for sure. It's something no one else does. Mixing it up is cool but I like that you're filling a void no one else is doing things with.
I agree, it is the reason I subbed!
@@donanders2110 Same, I did watch some of his videos from time to time, but now that he has his own interesting thing going on, I subbed as well, and I've enjoyed every episode so far. I think the channel will eventually grow quite well with the current content. One thing I'd like to see in the future, rather than randomly picking fans from his email, maybe have a website where people can list the fans and have them voted by the community for testing, doesn't have to include the files, just a picture and maybe some explanation.
And the community participation aspect is next level. Anyone can send a design, see it printed and tested! Really quite brilliant.
I subscribed as well when he started “the fanshowdown” I really like it, send a fan design because I liked it so much. I wished he did more fanshowdown videos! And like other people said, he is filling a void no one is on TH-cam and it’s a blast!
About the lights: the setup is definitely better than before and good enough as-is. If you want to improve, I'd recommend diffusing the light (If it's already diffused, diffuse it more) so that the shadows on you and your surroundings are less pronounced and distracting. That being said, Like I already said before: the lighting is already good enough.
and imho swap the locations of the light sources. If you're located to the right of the frame, it's just easier to look at if the light source comes from the left side and vice versa. Because he locates himself to the left in the frame, light from the left probably would end up making it look smoother, but yeah for sure diffuse it more
The hard shadows on the background are okay... But the lights creating them are too bright which makes them distracting and competing with his face. See my post for a more in depth breakdown.
Lighting is half of my job.
Yep try bouncing the brighter light off your wall to get a smoother diffusion of light.
@@deedee4757 bouncing light off a wall is hard to keep under control in a small, white-walled office but doable with barn doors.
You can use something simple like thin white wax paper for diffusion.
Would be cool to see the “turbofan compressor” driven at 2000+3000 rpm.
Also set up an exhaust fan with the exit turbine shape
@@MrPhil360 He should add a combustion chamber too :D
That's what I was thinking it looks like it should be running on a more powerful motor
@@craigleverone414 just get to the point, you want a jet engine, we all know you want a jet engine, lol
Graphite powder would make that monkey smoooooooooth af
I really like this series.
People try do design a fan,
everyone with his own mindset
and out comes a giant open research project that combines wild designs without judging the creators.
I have to clear some things here:
1: Propeller MASS has nothing to do with RPM. AIR FRICTION has biggest effect. (well, technically yes. Increased load on bearings cause increased friction, but it is insignificant in this scale)
2: MOTOR is still DESIGNED to certain POWER and certain RPM. Designing propeller outside of these parameters will make it fail on tests. For ex. Everyone's favorite "jet turbine" is efficent only when there is air rushing IN the fan... not when air is still.
3: NUMBER of BLADES is NOT equivalent of POWER/EFFICIENCY. More blades = more air friction (drag) = more power loss (actually the most efficient propeller is single bladed with counter weight)
4: If we read rules 1, 2 & 3, we get rules for winner propeller:
-fan must have less AIR-friction than original Noctua fan
-fan must be MOST EFFICIENT at moving air at it's size and power level. (we need to get max power peak of motor and it's rpm to calculate best fan)
-fan blade count to minimum, without losing too much pressure.
-fan must not disturb airflow before blades (pop, noice ( ͡° ͜ʖ ͡°) )
I probably forget this comment in a week. :P
Every time he talks about mass im like mass has almost nothing to do with it. Giving momentum to the mass of air you are moving is the biggest determiner of energy consumption. Then there is the efficiency at which you give the air that momentum, loss to heating from compression, turbulence, heating from skin friction.
Yeah you want to consume the greatest amount of watts possible from the motor and move the largest amount of air per watt consumed.
I would like to see a watt meter measuring the consumption of the fan in the videos.
@@nocare actually turbulence improves heat transfer
in fact, it improves heat transfer so much that when we do the math for it we start by forcing a turbulent flow and calculate the transfer, and then go about figuring out how to make our turbulent flow.
@@Thesupremeone34 I am aware however not all turbulence is good turbulence.
For instance vortices where the air makes no progress thru the radiator but instead sits in a dead spot and eats energy from the system.
You don't want laminar flow thru the radiator but perfect laminar flow off the blades would be ideal for maximum air flow.
So its a compromise game in the design. Most homebrew designs however are far more turbulent than optimal and thats what my comment was refrencing.
Are you going to offer a design?
It would be cool to see the compresor running vertically so the shaft doesn't droop. I feel like its losing a lot of energy to the oscilattion of the end off the fan stack
The snoot would droop
Supporting the shaft wouldn't be that hard. A diagonal brace with a spindle bush/bearing at the centre would solve that problem.
@@woopimagpie your very smart
@@bluezz5002 At least I can spell.
@@woopimagpie i can spell im just lazy, its true you seem smart
As a photographer: when in doubt, bounce the light off the ceiling.
As someone with a 1k lumen flashlight, point at the ceiling and everything is illuminated.
Depends. It can introduce a 12oclock shadow.
Imo, reflectors plus more powerful light but farther distance. Or use that difractor film thing used in LCDs to simulate a farther distance.
grovermatic - my whole house is lit this way. Well, ceilings and walls.
I moved into a new place a couple of months ago and it has those awful spotlights that were popular about a decade ago. Thankfully they were adjustable and I pointed them up :)
I kinda feel like there should be 2 categories, 1 for fans that fit inside the fan frame and don't go outside those dimensions, and 1 for the big "out-of-the-box" designs, so to speak.
I don't see why, the top 4 are inside the box fans already.
@@chasesan but then you have fans like this compressor design that clearly aren't able to reach their full potential. if for some reason you just want raw power and don't care of the massive amount of sound and possible logistics issues, maybe one of those out of the box designs cranked at their max safe RPM might actually work better. smaller ones could suffer either from great efficiency loss or failure at those speeds, as is the case with other types of fans/turbines.
at the very least, separating these special designs out makes it more fair. it's not that unreasonable. if anything, it's unreasonable that this is not done. it' kind of like putting an air conditioner against a ceiling fan. the A/C in a contest built for common ceiling fan would lose. the ceiling fan in a contest against A/C or other heavy-duty "climate control" devices also would lose.
there's also the option to ban out-of-the-box designs completely, but that's really not cool, either. let people get creative. but the conditions should be fair for both types of designs.
@@chasesan then he could give the larger, out of the box fans a bigger motor, so they can spin at a competitive speed.
I am on the hunt for the quietest fan I can find, and this series has been very educational. Thanks, and keep going for as long as your fans will allow!
“The golden ratio based off of...” just about damn near everything dood
Id like to see what that fan can do on a stronger motor.
I wonder if 140mm fans use different motors. Would a 200mm fan motor fit in that Noctua?
industrial 3000rpm?
it would do better in terms of cooling but the already loud compressor fan would be extremely loud. its frankly a bad design.
ZupaSanic that’s engineering not design bruh... Ruben made my day
I remember seeing videos back in the heyday of CD roms. They were trying to spin them faster and faster and they reached a point where they had to start redesigning the CDs with a supporting criss-cross of stabilizing material because the CDs were exploding in the devices.
You could actually go two directions- something with more speed or something with more torque. If you added some torque you could get some bigger blades spinning.
I always get sidetracked on projects but at one point I was visiting my mother at her house. I had my harmonica with me and I noticed that it gave a really cool noise when the ceiling fan was on. I mean, I'd sung through a fan before but since it was a bigger, slower fan and not directly into it it was a different sound. I've always meant to set up a really quiet computer fan with a slow engine and see if I couldn't work something out small enough to put between me and the mic as an effect, maybe with a variable speed adjuster. If it had a consistent enough pitch at speed a specific speed and enough control of speed you might even be able to tune the fan noise to the key you were playing in.
Let's see how that complicated fan contraption goes. And a golden ratio fan~ cool
Wow, never clicked on TH-cam and seen "Uploaded 20 seconds ago" before. Super excited! LETS GO!
Same thing with me. :D
20 minutes for me
Always fun. Happens maybe once every two years to me lol. Looks like I was 26 minutes off
"first". we say "first"
"I run a YT channel"
"How is it going?"
"I ve got many of fans!"
Just Fans from all over!
it's fanny
The Golden Ratio is so pleasing to look at and silent too! ♥
Do the three blade fan without the duct! Let's see how much of a difference that lip actually makes?
absolutelystupid ikr
Or in reverse, add the duct to the leaderboard fans, see if they do better with duct
A considerable amount.
Great idea!
What would the stators attach to?
Man I wanna see that big fan spun at 2000rpm instead of the 700
I want to see it at 5000!
i want to see it at 10k!
can you please put the turbofan compressor on a redbottom and spin it at 2000 rpm and run the test on it and see where it places
I'd love him to show noise normalised results too. It would give us more content without him having to put too much time into printing more fans.
Ideas: Use a pack of Straws to direct the flow of the smoke to add "Lines" for the video. Next, add Watts used to the data set.
If it hasn’t been said yet, you have really grown your fan base. 😎
I love these fan videos. Each one has something that blows me away. Last week was the bedroom toy that won 5th place overall and this week is the full blown multi stage jet engine style compressor. Something tells me there are a few eyes from noctua, corsair, thermal take and cooler master taking notes. You're learning more about what an industry could do to improve by messing around with some people on the internet and its amazing.
Im pretty sure all those brands are doing this daily but in a real lab
@@KalLanPIDT bug companys often dont try lots of crazy ideas but rather try to improve what they have so from something like this they can take promising new starts
I'm here because of the Fan Showdown videos, and their interaction with the audience and the creation of new fan designs. It is interesting and captivates me to watch you.
Yeah,me to. You could say I really got sucked in.
I like how we're watching an upcoming good TH-camr because he actually reads comments and takes suggestions and even says he's trying to learn to make his videos higher quality
and he even improved his print quality
I just realised that the "Fan" in the "Fan showdown" Has 2 meanings, that's pretty clever
The compressor concept was the fan I hoped for and expected from this series since the very beginning. Happy to see it was submitted and built!
An issue with dropping room temperature is the temperature delta will always be higher with a cooler room. The energy it takes to raise the temperature 1 degree at a lower temperature is slightly less than the energy it takes to raise 1 degree at a higher temperature due to the density of the water due to the heat. So at a higher temperature you do lose heat a bit quicker. Now in the case of changing room temperature it may not have a large effect, but you are increasing the possible temperature delta window by lowering room temperature as well. I would recommend running the previous fans again at as close to a static room temperature as possible, in a room of the same size so your air cooling capacity is also not different (air volume)
TLDR Retest all fans at same room temp, as delta limits have changed, and same room sizes for same air volume.
I would CNC (Steel) this Axial comressor, fit it with bearings and an shaft, and hook it up to a 300W Laboratory Power supply, and ramp it up to 20k rpm ... Static pressure would be mind-blowing, but so would noise.
I already have a 22.400 RPM Quad- Counter rotational axial fan assembly... that sounds very delicious like a turbofan engine
Idea. You should build a rig with all your favourite the fan fan's, regardless of performance, more for aesthetics. The fan fan build. It would look so awesome to see a build with all funky different designs in it!
I didn't think I would be a (lol) fan of this content, but it's actually interesting. I like that people send you their designs, you print them and pit them against each other and test them to see which designs are best.
Makes ya realize exactly how much engineering goes into something as simple as a fan and it's shroud.
You definitely have a new sub here.
Thanks.
Put the shroud onto Thomas’s fan, see if it assists/improves his fan, maybe get that guy a job making fan attachments/accessories
I would love to see you overvolt the noctua hub with the turbofan compressor on it to try to reach that 1800~2000 rpm range to hear it and see how it does!
"you know what happens when a fan is developed under 30 min..." hahahahaha yeah, that is right, good job again thomas
the mass of the blades wont slow the motor unless it's causing drag on the bearings. I think the problem you're running into is, pairing the torque and rpm of the motor with fans not designed for that motor. that compressor fan needs more torque, whereas other fans might need more rpm. the motor isn't optimum for the fan. give it 24 volts!
Why wouldnt more blades make the motor run slower? More mass makes it harder for the motor?
And theres more pushing air by the blades so more resistance i guess
@Dr.Cemong so they do make it run slower cuz u need more volts >,
@@fabianvandermijde4066 Accelerating the motor yes. More mass = slower to accelerate.
But that's only half the story, the flow through the blades is the biggest part of the drag (on a properly constructed fan that is). More blades at a lower attack angle might very well be way easier to drive than a few very steep angled blades.
@@fabianvandermijde4066 More flow, more power.
Let's say that fan motor can develop max 12v 2a, so 24w max.
So if the man move a stream of air with 24w of power at 700 rpm, the motor cant go faster.
It's like a bike, fatter rider will accelerate less than the skinny one, but they can achieve greater speed if they have more power.
@@Kalvinjj thats basicly what i said aswell right? Or am i understanding it wrong?😅
dont even think about making not fan related video, i stumble on this chanel becaus of your crazy fan experiement and now i am addicted
Dude the fan videos are WHY I'm here lol. Your other stuff is great too, but I love the concept of people submitting fans for you to print and compete.
NUMBER 1 LIKE! Enjoy the fan showdowns - keep them coming - perhaps expand to a 140 or 200 mm category!
“I’ll give him props”. 🤣🤣🤣🤣
Wow, things are heating up in terms of design. I wonder how the last fan would fair with your drone motor?
Nice pun, everything pulled above 80 this time around. I'm considering making my own entries tbh, it would be a nice hobby.
Seeing as he has a shit motor that belongs to the noctuo fan, it's not weird that he can't actually test fans properly.
Seriously, that compressor would be amazing for an EDF RC plane.
The engagement with design and testing of fan made fans is really captivating content in my opinion. Keep up the fan vids, they're fun.
I am a huge fan of the fan videos. So please do keep the fans coming for the fans so we can maintain our fan fan fandom.
Gotta get some Leds for your face lights. The yellow tones of your halogen face lights and the blue tones from your Led background lights will prevent you from ever getting a good color balance. Need a diffuser for that face light, super harsh edges right now. Also, move your face lights 2-3 feet away from your face and up maybe a foot from where they are now. You want the shadow from your nose to fall into the crease between your cheek and upper lip.
Anyways, love the fan duel vids!
Bump! A diffuser (or a stronger one, if it's already diffused) will go a long way
I’d like to see a counter-rotating dual fan design, just like the Scythe Fuma 2 fans, but in one mount, just like the compressor.
It would work really well, but it would be as loud as a damn freight train lol
Currently trying to make one of those. I dont have a 3d printer so I'm not sure if it will work as well as I'm hoping.
am curious to see if the compressor-style would work better if you gave it a motor that had the beans to push it to its intended RPM....
Absolutely the best thought process and execution yet ! The Turbo/Compressor Fan is for me the winner, just because your fan motor can’t propel the fan assembly doesn’t mean that it doesn’t make the board. In my opinion you should rig it up so it will spin with the same rpm as all the others and compare cooling capability. Because it deserves to get the win, as the execution, design and tolerancing is outstanding!
These fan showdowns are the reason I subbed to this channel .
I'd like to see that ducted fan compared to itself w/o the duct
So the next step would be something like a fan with gear bearings so you have a compresor with different level fans going at different speeds so air accelerates by steps or something.
That's just more mechanical load, so the motor will spin even slower...
I think that what you are saying is to just make a jet engine and put it on a pc fan
give each fan its own motor with different RPM is simpler to design i think, and lessen the burden of the motor so it will be able to spin faster.
i think unless he decides to just convert to 100% resin printing [or maybe powder] that those designs are just bound for failure, especially if put on the type of motors actually required to drive them at their max potential. that's a lot of stress for some small, moving parts like gears. any stray material or malformed geometries greatly impacts performance and stability.
I'd love to see if the duct on "The Ducted Fan" improves either the noctua or the #1 place fan (forget the name)
Very nice. I love seeing this simple engineering and your experiments with peoples designs.
As somebody with no experience in lighting, whatsoever, I hope this still means something.
You got the lighting perfect dude. Fucking perfect.
Id like to see the compressor on a powerful motor to see the baby go!!!
How dare he not mount Ruben's work of art onto a more powerful RC motor to show it in its fully realized glory?
I'll work on a modification to fit on the RC motor :)
I want to see that jet engine thing running on an over volted fan
Dude, you got me hooked ever since you made the Hyper 212 a water cooling block. The fan showdown is another step into the unknown, to the point that a manufacturer reached out to you regarding the top design. You're doing something no one else is doing! Keep rocking dear sir...
Watching the smoke test while you talk about the heat numbers is a nice touch. Please do this more.
your lights seem very bright n focused , maybe get diffusers if you haven't already, but otherwise the lighting is nicee
take a shot every time he says "but" or "literally".
RIP
@@MajorHardware no worries i have coke
SOOOO when are people going to realize the RPMs a compressor fan needs to compress air is 10s to 100s of thousands of RPM at that size? Just think cars and power adders.
He wouldn't have to get it even up to 10,000 3000 RPM would be plenty to demonstrate at least some of the efficiency though it didn't help much that he installed the stationary blades backwards
as an areo nerd this series is really cool, its fun seeing people trying to implement real aircraft stuff into fans
I appreciate the discussion of why they (the different fans) are different.
Imagine the golden ratio concept fused with the turbo compressed concept...
Would be so silent while powerful....
I feel that advanced lip would go great on that multilayer compressor, as well as putting the RC motor on the hub
We ain't trying to start fires with those rc motors bro!
You should redo that compressor in resin and run it with a more powerful motor.
Please keep making these. I've been binging on all your old content! Some of the newer stuff is just insane.
I love the fan videos. Fans by fans. I love these cool ideas even if they might not work, might not perform amazing but it is the thoughts that really do make me think more. If I had a printer, I would design my whole computer case and fans and all the doodads with it, out of all these ideas.
That jet engine fan with the cone would look cool with the rounded duct and that's a great idea - to combine some promising features together.
Ps. The lighting is worse now imo.
"This fan was made with the golden ratio"
Me: *furiously scans the comments for Jojo references*
i was doing the same
Same, but for JoJo and TOOL. If you like the golden ratio, check out their song Lateralus, the entire song is based off of it
The fan motor is not rated for that heavy compressor fan
Wow thanks I didn't know that
Something about optimizing fan blades is so satisfying or watching people try to optimize fan blades.
Never apologise for the fans, your fans want more fans!
"If the engine is powerful enough I guarantee this will be the best"
Couldn't you say this for pretty much any design?
Maybe he's saying it's sturdy enough to take any amount of RPM, even levels that shatter other fans?
The motor needs more torque for this piece to function properly I think
Those Fans really needed here in my country its super hot here
I think your fan conceptions for video content seriously it's an amazing and inspired I watch all of your videos and am a huge fan. 👍
My favorite part of these videos is how nice the editing is. Like it has that air of janky suffedness but its also so clean
These videos are just soo freaking cool, im pretty new to them and to your channel in general, but man, I love when people come together and inspire others and all that. Very cool.
Your fan videos are what bring me here
Love the fans and fan content. Definitely interested in seeing more things from you that aren't fans, but I'm watching every fan video!
It's really cool to see your channel grow and watch you iterate your style and execution of these videos. A+ mate
I subscribed to this channel solely for the fans. Keep it going
Not calling this series "Fan submissions" really is a missed opportunity for a good pun =P
How about "fan service"?
Or maybe Fan-Tastic designs
I just stumbled across your channel and I wasn't terribly impressed with the first video I saw in this series (it wasn't the first in the series, just the first on I saw) but the SECOND one hooked me. I've become a (here is comes) FAN. They keep getting better because it is a perfect demonstration of how a competitive market works where everyone gets to present THEIR idea of the perfect concept for a cooling fan. You could almost build a TED talk around this series. That last, shrouded, ducted, multi-stage fan with the stators was just freaking COOL! The reason it was so slow was the sheer volume of air it was trying to move with that teensy, weensy motor. It was, clearly, too much fan for that motor. As you noted, If you could spin it at 1600-1700 RPM it would, literally, blow the competition away.
Not even close to sick of the fan engineering design videos keep em" comin
Oh and idk if vaseline for a bushing bearing lubricant would've helped any on the fan styles with friction or flat mounting horizontally to earth's surface so not hanging off shaft vs gravity basically a lil support frame to hold it 3 inch or so off desk so airflow has escape path on backside , i wanna put the rollz royce cone on the golden ratio in a duct with propper stretch tolerances :)
The fan videos are the main reason I come here
All I can say is brother you have started something and it is the war of fan and I am a big fans.
The fans are the only reason I watch, lol. Try over-volting the motor on that compressor!
I come here just for the fan videos haha.
Also I can help you setting up your light properly.
-Put the lights a little above your eye level will be.
-Use only half power or less, the goal there is to get a small light ratio between you, the foreground and the background, so, just try to make it even.
-If you can, use light diffusers, and don't put the lights too close to you, but also no too far.
That should give you a smooth nice lighting.
Oh and if you want more consistent "smoke" flow, try putting a hose in between the jug you use or directly to the smoke/fog machine. The larger the hose diameter the slower the smoke flow speed. I've used about a meter/3 feet long cuts but longer one might even out the smoke machines output.
A plastic bag works too for smoke storage and you can squeeze it at a more controlled pace than pumping a can.
Definitely worthy of a special award of some kind, even if that's in the form of a follow-up to explore the potential with a more powerful motor. Hint, hint ;)
A jig to support the rad and fan in horizontal orientation would all-but eliminate the droop. There may still be some wobble due to it not being perfectly balanced, but it would be nothing compared to the droop.
that compressor design is well done. Looks like a proper turbo server fan. He can get away with not much blade curve because of the stators.
The fan showdown MUST GO ON!
