This. Would be interesting to see it with some heavier lube to see if that reduces vibrations, and then stress test it to the max with attaching it to a real motor ;).
@@MajorHardware Print it in resin, polish it super smooth, use a slightly heavier lube, (maybe) balance and weight match all the gears, and it would be a lot quieter, and possibly more efficient.
I can't believe it actually worked! That was a lot more airflow in the smoke test than I expected. When I tested the earlier version myself, it felt like it was blowing more air sideways than through it. The fact that it scored at all is a win for me, let alone not last place! Also, that filament is beautiful. Thank you for giving the fan a shot, and I'm so glad it worked for you.
Great work! I was thinking of designing something similar a while back, but laziness won. I like that each gear is it's own impeller of some sort. Great thinking there.
78 dB is actually so loud that in industrial settings, hearing protection is almost mandatory. I love this fan. Great looks and it even finished a test. That's a win in my book.
Totally okay this test lacked three competitors, nothing else could have been as interesting as that one. Totally deserved a solo spot and place of honor, just wow design
Just thought I'd mention it, a good way to lubricate 3D printed gears and chains is to scrape a pencil over the surfaces which will coat them in graphite, which is an excellent dry lubricant.
06:24 ... That engineers-laugher... that feeling when you might as well have created life like Frankenstein and it's just thrilling, no matter how stupid! That's why I enjoy this channel, in essense!
There's no question about it, it's absolutely fascinating on how people perceive a fan and what ideas they have to execute it. The numerous of different designs and how well they perform just shows how creative people are even with a commonly used and a simple electrical device.
As a fan, it's garbage. Loud, poor cooling and with most of the energy input for cooling used up overcoming friction. As a piece of design though.........it's a thing of beauty.
For your smoke pipe: For laminar flow you can use drinking straws in the middle if you use an orifice and at the end if you want the whole diameter as opening. (Thats at least how it works with water, and drinking straws are cheap)
How have I never noticed the Picard facepalm bust before? I mean, I'm not an avid viewer, but I have been watching the Fan Showdown, and yet this is the first I have payed attention to it.
I'm gonna be honest here. I have no idea how I came across this channel, but something about these unique fans has me captivated and interested. I love it
After watching the smoke machine output for a bit, I had the thought that you might want to add some sort of bypass or expansion section into your laminar flow nozzle - it looks like the smoke is billowing when it comes out of the end of the tube, which (I think) indicates the pressure/velocity at the outlet is a little high.
I'd be interested to see that design running without the clock blades. The idea of putting mini-blades into the planetary gears is beauty. Like you, I don't care how loud it is... That's just wonderful.
I've actually been thinking of the same thing for quite some time, my motivation for doing it is to remove the hub from the center and put it in the corner. Put the gears on the outside and put the driving motor in the corner. How much of the square can be put into moving air? Have a look at something that I came across that might be interesting to use. I leave the watch address at the bottom of my comment. Just add it after the youtube address. You off course have to leave the default Noctua setup to do this. watch?v=76yRObMIwa0
I Know that I Super Late to comment here but The Tic Toc Clock Fan planetary fans look like they were designed to push air when they rotate and the top fan pulls air so the two are working against each other. I might be wrong, But if I'm right I would like to see a fixed version of this fan to see how it would actually perform when properly designed.
I'm curious, if the RPM is higher once the fan 'settled'/smoothed out. If it is, maybe a retest is in order as I'd imagine you're averaging over the entire test period so temps may have dip towards the end of the test. It's unlikely that it will change the result by much, but it's got me curious.
Awesome fan and nice work again. Put some straws in the end of the tube and seal the space between them to direct the flow (like a patern of individual streams of fog)
I've had this idea since the first few fan showdown videos but my bad fusion 360 skills prevented me from being able to follow through but I'm glad someone else managed to do this!

If so maybe push your Patreon more, and I'm not sure how much your sponsors are paying you, but make sure it's a good rate by checking against other UA-camrs - e.g. EEVBlog doesn't take sponsors, but Dave said that at around 50k subs the average sponsor would offer $3k per video in groups of 3-5 videos per contract (and that was the offered price without negotiation). Also if you're ok with revealing it, what is your day job?
Seeing all that smoke reminds me that many years ago in a previous life I was a sysadmin, part of my job was looking after a decently sized server room. Bosses decided to test our emergency response procedures by simulating a fire in the server room (it had a lot of electricity in there... so logical, I guess), using smoke generators that used peanut oil. They turned off the alarms in the server room, so as not to trip any automatic sprinklers, started the generators, left the server room and closed the doors. Nothing happened.. the room was pretty well sealed to keep the cooling systems cold air inside and dust out. Nobody outside the server room or it's little adjacent office (where I usually sat, but I was elsewhere at the time) knew that anything was happening, the fire service, warned of the test patiently waited for an alarm that never happened, as the alarms were disabled. Eventually the light dawned on the bosses, they opened the door, and the firies* called in (by phone) about this time I showed up. The peanut oil mist had got into every corner of the server room. Apparently the drill went well from that point, except I got in trouble for shouting and swearing at some people who were going to use water extinguishers on an electrical fire, and potentially on live servers. Go figure. That night the problems started. All the servers, switches, power supplies and UPS failed one after another. Peanut oil is very sticky when applied as a mist. Being a mist, and pushed around by many many fans, it coated the insides of every machine, then dust stuck to the sticky oil. The dust got in, as the server room doors were left open to clear the copious smoke. Every piece of equipment eventually overheated and shut down, some power supplies even shorted. I spent many many hours stripping and cleaning each piece of equipment. Tape back up system hardware just got trashed and replaced. Database admins, software engineers etc all had to be called in to fix errors due to the "sudden and unscheduled server stoppages" Due to the downtime much data wasn't collected, many processes had to stop. Quite a few components needed replacing. It was a very expensive fire drill. If only they asked the people who looked after the equipment for a bit of advice before hand * our nickname for the base fire service
@5:27 perhaps applying some powdered graphite as a dry lubricant on the outer planetary gear ring will help get it to roll more smoothly. Im actually surprised the white lithium grease worked as well as it did.
If you are looking for a good lubricant for use with any kind of plastic or Light-use metal parts, I would recommend liquid silicone. I have used it myself on several occasions and it is an absolute dream to work with, just a couple drops would probably be able to coat all of the surfaces of that fan.
that fan would be ideal for a case-con. the noise gets the attention for sure, the intricate mechanism is sure to keep it. the only thing it is missing is RGB... but having no RGB is just another detail that makes it unique. a 20 cm version should be interesting.
Notice how in the smoke test the air is only really getting pulled through the middle of the fan. This actually makes sense because the outer side of the planet gear fans is essentially stationary relative to the rim it is rolling on. The clock hands are by far the fastest-moving part of the fan, which probably also helps with the RPM.
Clockwork is so amazing. Sounds like it has tons of flex and tons of tolerance. If it had less tolerance it’d probably get stuck though. Lubrication is key to clockwork, but quiet gears require a rigid structure and tighter tolerances. Sadly, plastic isn’t known for either of those capabilities. I wonder how the fan would perform if it were made from another, more sturdy, material.
I reckon it would be worth trying to get another small fan/gear in there. Maybe two. The idea being to reduce the area *_not_* covered by fan. No file needed? ;)
Fantastic! I was wondering how long it would be before this design popped up, I'm surprised at its performance too, it actually worked well enough. Good Job.
Use superlube multipurpose ptfe oil. The Teflon will make it run much smoother. There is a grease version but greases are for longevity and moisture reduction for gears, motors and rails. Lithium and metal greases are for metal to metal applications. When you clean your fan motors you use mineral oil so that it also lubes the stator.
I haven't watched in a little while. You were explaining the smoke people thinking you were ripping fat vapes hahah funny but when I seen the smoke I realized why lol I have to say you definitely stepped it up from your earlier videos. Great work. Love the research your doing with so many creative people!
Big props to the person who made that, despite my following criticism, I still find it amazing: but I wish it had been done without those huge armed blades on the center gear. The whole point of testing that design is to see if mini-fans rotating around the hub, instead of just blades, would make the fan draw in/out air better in any way. By adding the huge blades in the center piece it defeats the purpose of that test.
The smoke test was really interesting actually. The side shot showed that it pulled air from the outside and blew it through the fan close to the hub, which is ironic because most fans have the exact problem, yet there seemed to be a decent dispersion of air flow on the backside. Be cool if we could get a shot of the fan in the smoke test from the "afterburner" point of view. I also noticed, some smoke boiled over the edge and ran into the "thrust column" on the backside, getting pulled into the exhaust trail.
The angled gear teeth actually quite clever. It might just look like it's stylized but if i'm not mistaken it's the only thing holding the gears centered so they don't wander and eventually fly off.
That is equal parts engineering and art! Now you need it permanently rotating at something like 15-20 rpm on the fan board to show all the moving parts in their glory :)
This fan is MY personal FAVE by far. (As well?) It's SOOOOO Mezzzzzmmmerrrrriiizzzziiinnngg to watch turn/spin no matter what speed. I LEGITIMATELY thought the gears were going to unseat and the fan was going to explode.. NOPE!! The grease was a great idea. Again.. SsssiiC fan!
What if you had a mini fan on each of the cogs rather than the large one in the middle, or have mini fans on each cog underneath the large fan so like 2 layers of fannage?
Overeingineerd, louder and works worse than his cheaper competitors, way more moving parts so more probable to break. This is really a luxury watch by the look and the spirit! Not to hate it, this is awesome as a project, really impressed!
Im happy that the designer went with the double helical gears instead of the herringbone, I believe that was key to making this work. The herringbone are soo intolerant of misalignment. The white lithium grease is perfect for this, lubricated enough to allow the gears to wear in.
If it was done in resin and smoothed out would it make any difference though theres a lot of surface area and friction is likely a huge factor in performance here so we could see some pretty good gains.
we need a sub-category for volume, you really should be tracking that on a spreadsheet too. I think it would be hilarious to find out the loudest AND most efficient ways to move air are. imagine having a fan in your PC that only spooled up as an alert and was actually a small air raid siren. "HEY, TEMPS ARE TOO HIGH, NOTICE ME SEMPAI!!!" WAAAAAAAAAAAA
Great video! As other have mentioned, we should have different categories now that you've been getting so many different designs. "loudest" "most unique" "largest that still spins and cools" and lastly "crowd favorite". That last category should be something you put up a poll of some sort for.
This is an awesome design! the next time you do something with gearing you should try a different method of lubrication too, and filament types(is there one that is more porous then another?). You can get a dry lubricant (Graphite powder) i was able to find some in the automotive section of the hardware store. I am curious if that affect on the overall performance. There is usually a break-in period for gearing mechanisms, especially due to the inconsistencies in 3d prints; which explains why after 20mins it ran a lot smoother. Keep up the fantastic work!
I wonder if it is possible to make a geared fan the has two sets of blades that because of the gears would spin in opposite directions? It would have to be twice as deep and the first fan being smaller in diameter would have several small gears between outside ring of that fan and the shroud and the gears would in turn move the outer fan, hopefully, in the reverse direction. The outside fan would be attached to the center of the hub but able to spin freely. Just an idea I had but I don't know how to use the software to design it.
According to Purdue, 77dB is a car driving at 65MPH, 25 feet away. That is loud. Is it quieter now that it is fully lubed and all gears are working better together?

@@markp8295 that's what makes engineering fun!
Maybe the smoothness of the resin can improve this amazing complex fan.

Be a great fan to run at a low voltage to just have it move slowly as an art piece in the background.
Print out a 250mm fan variant, then just find a case it'll actually fit into!
Maybe instead of a fan motor use a clock motor.
You'd need some gearing between the motor and the fan to prevent the motor from getting stuck
@@patrickhector hah...

Thats not a fan, its a piece of art.
With that noise, it just annoys the heat away from your test bench.
Cpu purposely didn't throttle because it knew it'd have to put up with the noise a second time to make sure the first failure wasn't a fluke.
I love this.
Someone make one with a gear ratio that just makes it spin SO FAST
The problem with that is that it would require a lot of torque, which the little motor can't provide

The side shot showed that it pulled air from the outside and blew it through the fan close to the hub, which is ironic because most fans have the exact problem, yet there seemed to be a decent dispersion of air flow on the backside. Be cool if we could get a shot of the fan in the smoke test from the "afterburner" point of view. I also noticed, some smoke boiled over the edge and ran into the "thrust column" on the backside, getting pulled into the exhaust trail.
The angled gear teeth actually quite clever. It might just look like it's stylized but if i'm not mistaken it's the only thing holding the gears centered so they don't wander and eventually fly off.
That's amazing fan! :)
I am sure someone will make even better (functionally) version of that! :)
You should probably check the rpms again. After wearing in the gears it probably went up some.
Wow absolutely awesome! I honestly had a smile on my face during the entire video and laughed out loud when it worked!!
Just brilliant!!! 😃
That is equal parts engineering and art! Now you need it permanently rotating at something like 15-20 rpm on the fan board to show all the moving parts in their glory :)
That is the single most insane looking fan that I've seen. It makes the vase fan look entirely plain.
This fan is MY personal FAVE by far. (As well?) It's SOOOOO Mezzzzzmmmerrrrriiizzzziiinnngg to watch turn/spin no matter what speed. I LEGITIMATELY thought the gears were going to unseat and the fan was going to explode.. NOPE!! The grease was a great idea. Again.. SsssiiC fan!
I was waited for the day someone would submit one with gears, and wow, I'm impressed it got as far as it did!
What if you had a mini fan on each of the cogs rather than the large one in the middle, or have mini fans on each cog underneath the large fan so like 2 layers of fannage?
Overeingineerd, louder and works worse than his cheaper competitors, way more moving parts so more probable to break. This is really a luxury watch by the look and the spirit!
Not to hate it, this is awesome as a project, really impressed!
Im happy that the designer went with the double helical gears instead of the herringbone, I believe that was key to making this work. The herringbone are soo intolerant of misalignment. The white lithium grease is perfect for this, lubricated enough to allow the gears to wear in.
If it was done in resin and smoothed out would it make any difference though theres a lot of surface area and friction is likely a huge factor in performance here so we could see some pretty good gains.
we need a sub-category for volume, you really should be tracking that on a spreadsheet too. I think it would be hilarious to find out the loudest AND most efficient ways to move air are.
imagine having a fan in your PC that only spooled up as an alert and was actually a small air raid siren. "HEY, TEMPS ARE TOO HIGH, NOTICE ME SEMPAI!!!" WAAAAAAAAAAAA
Great video! As other have mentioned, we should have different categories now that you've been getting so many different designs. "loudest" "most unique" "largest that still spins and cools" and lastly "crowd favorite". That last category should be something you put up a poll of some sort for.
This is an awesome design! the next time you do something with gearing you should try a different method of lubrication too, and filament types(is there one that is more porous then another?). You can get a dry lubricant (Graphite powder) i was able to find some in the automotive section of the hardware store. I am curious if that affect on the overall performance. There is usually a break-in period for gearing mechanisms, especially due to the inconsistencies in 3d prints; which explains why after 20mins it ran a lot smoother.
Keep up the fantastic work!
FAN SHOWDOWN! Man I love this series. 27th place, nope I was off a few.
I wonder if it is possible to make a geared fan the has two sets of blades that because of the gears would spin in opposite directions? It would have to be twice as deep and the first fan being smaller in diameter would have several small gears between outside ring of that fan and the shroud and the gears would in turn move the outer fan, hopefully, in the reverse direction. The outside fan would be attached to the center of the hub but able to spin freely. Just an idea I had but I don't know how to use the software to design it.
According to Purdue, 77dB is a car driving at 65MPH, 25 feet away.
That is loud.
Is it quieter now that it is fully lubed and all gears are working better together?
I was literally about to ask what if you oiled the gears and then you oiled them. Love this Chanel.
This is a piece of art!!
