and that super low sound output would be even better with a much higher resolution 3D printer, BUT, the hardware couldn't accurately print out the veining on the edge of the fan blades
for looks, its one of the best looking fans we've had i think. make it with some clear PLA and mount it on an rgb hub and youd have one hell of a sweet looking fan
i think the only reason he hasn't is that there's a few episodes early on where the meter was giving incorrect readings until he noticed and was able to fix it so he'd have to retest all those fans. also he changed rooms which would again require all those previous fans to be retested since the noise floor changed.
My thoughts concerning the vase: 1. How would that design perform if it was reversed (read: mouth of vase attached to hub, base of vase forward) ? 2. Could the vase be more efficient if mounted as a "blower" instead as a fan? 3. What about adding internal fan vanes inside the vase in order to move/focus the air toward the hub?
I think adding some blades on the outside at the bottom along with a frame at the bottom will increase performance significantly, and more exciting to see
Yay, you chose my Starship fan! The thermal throttling is obviously by design, to mimic Starship reentering the Earth's atmosphere in a fiery blaze of flames and plasma! 🔥
I knew there had to be a reason you made the hub square. The small size means the fan should be able to move a good amount of air due to the RPMs, if the hub wasn't acting as a wall for 70% of the blades.
I was thinking the textured surface (printing artifacts) really hurt the noise, but then ALL the fans have the same limitation in that regard. I would still like to see how much better a resin print of it would do.
If nothing else, would be nice to as a final episode of the season reprint the top 10 and do a breakdown of them all. No need for smoke tests for all 10, would be a lot of work. But just to get the data for all 10. Would elivate this from being just a fun thing to watch, into something potentially useful imo.
or have some normal blades in the 'core' of the vase, the outer bit seems to suck air in just fine it just needs something to direct and accelerate the air once it's in.
I think the main issue is that no matter how you compress the air inside the vase it is expelling it before the shroud of the motor housing, the shape would have to be almost flat bottomed to enclose it in the fan housing, and then not looking like a Vase. (IMO) Maybe a shroud/ducting made of clear PLA? so you could see the shape inside.
When something you expect to do well does well. Who is impressed? When something odd does well We are all surprised. And the Vase looks cool. but needs assistance with the Cooling process. Comment section go Brrrrrrt
Hey man, just want to say thank for the fan showdown series. It's great to sit here with my sons and watch every episode . They cheer it on a d it gives us something to look forward to.
@@justincoleman9776 Since a lower Delta is better, if you divide that by the decibels then the higher decibel count would be better. This seems kind of counterintuitive, but the implication is that those decibels are keeping the temperature lower. So then to find the best fan, you would have to find fans with the same delta, and the lower decibel count would be quieter for the same performance. Maybe this is just over complicated?
I'd love to see a google doc of the entire list of fans in the show down. I love looking at the list but it's so tough to read now that there are so many fans on there! Awesome episode as always
I think the problem here is that the angular velocity is so much higher at the widest part that it will keep throwing the air out perpendicular. This is one of the reasons for ducted fans and why you want the fan blades on non ducted fans to be as close to the walls of the chassis as possible without rubbing. Ducting the fat end might improve the performance a lot, but it would also change the visual component a lot making it a lot less desirable.
The vase seems like it pulled air into the core and since it had nowhere else to push it, it dispersed it around. Whoever made that is onto something. It just needs some way to push the air into the core, or redirect it around the hub. I don't think you can see it on camera, but there is a vortex forming inside of the vase, but the issue is, soon as the vortex forms, there's no exhaust. If you put any liquid in a vortex and you give it an exhaust, the velocity of the fluid on the other side of that exhaust is much higher than what most fans can push. Speaking of vortexes, why has no one made an air pump fan yet? You know, those things that you find inside vacuum pumps and blowers, which look like a fan inversed.
Please start using the NF a14, I want to see these fans in 140mm! There is so much more space and torque on those blades for more unique stuff also more varience in sound, come onnnnnnnn
The vase is sucking in loads of air tho! it has a lot of surface area to catch more air, if it was engineered a bit more, u could create fans inside to force the air back, and create a lip at the base of the vase up to the fan housing to stop air escaping, if I knew how to, or even had a computer, thats what I'd send in lol
I think it might have more performance if there was a skirt or something on the bottom to keep the air from scattering before it passes through the fan hub.
I am a lighting designer and operate light shows for concerts. I am very impressed with the vase hahaha. Not a lot of people think about it, but for the audience to be able to see the light beams at concerts and other events, there needs to be smoke or haze to give the light something to reflect on and every new setup it takes someone like me time to come up with the best solution for that area, stage and especially outdoors to account for wind and such to be able to have smoke where it's needed at the moment it's needed and in the quantity it's needed without preferably letting the whole stage disappear in smoke. This vase actually does a nice job of smashing the smoke into a kind of thick haze like smoke. I could see use for it hahaha :p
If the vase had a duct around it from it's widest point down to the fan shroud i think it would work quite respectably. Although, that much weight hanging off the fan motor like that is more than likely killer on the bearings.
There are probably a few options here: 1) Turn the sides into a neutral cage of rounded bars and the bottom into a conventional fan, leaving the top as a blower running in reverse 2) Add a retaining funnel shroud over the fan frame, so all the radial blowing translates into linear sucking 3) Embed the vase inside a circular "Stonehenge" type heat sink rather than a big block of fins on one side, and let the design cool a CPU by doing what it so desperately wants to do: bringing in air from literally everywhere, and then exhausting radially from the base.
@generalhardware I know you don't get like a million views on these videos, but they are seriously satisfying to watch. Total comfort media.. Love what you do brotha. keep it up!! :)
It would be really nice if the excel sheet would also show the noise level recorded. An extra test that could be done in like a final round could be a noise normalized test: adjusting fan speed to reach a given noise level, and see which fan cools the best.
Stand the vase up Slow it down And spin it the other way With some sort of air freshener under it And you just might have a really cool looking air freshener system.
Love the fan showdown series. It's the only thing on UA-cam that I reliably watch. I have a suggestion for season three: season 3 you should noise normalize the fans. Set a db limit and report the rpm. Then lock the fan to that rpm for the test.
If the blades were smoothed with symmetrical teeth, the engineered one would perform more quietly, and rank higher. Precision to the design is key to something like that. If the vase had more angulation and the base had blades it would dominate. Great video! Always amazing content 😸
The NoCoDaf and even the vase are inspiring. I already submitted the Turbulence fan which you tested last episode (thank you by the way) but now have some ideas for a new design.
The vase is a spectacular exaust fan, we can see as it sucks the air but have no focus on pushing it, if modified on the area of the frame it can become a real contender to cool a CPU. And it's silent. And it's beautiful.
I think if the base of the vase was lower so it just fitted in the fan opening it wouldnt spit out so much air on the sides. I think if you would like compress the vase down in a way where it gets less long and more wide it would maybe keep the system cool enough
For the vase, create ducting around the outside fan casing (can't remember if it's convergent or divergent for pressure increase below speed of sound), and then as someone else said some internal Vanes to guide the airflow
Great to see one of the reddit fans making it, design wise I'd say the atom is visually one of the best with its clean form and clear inspiration. Anyway, so what are the odds off one of the geared multiple blade designs making it to a video? I'm biased to the original (given I designed it...) but there are a few now and I'd really like to see any of them tested.
The way the vase was sucking in was quite wonderful.. I bet it would perform significantly better if there was a shroud around the frame of the fan to the point where the vase closes toward the hub of the fan. The design has a huge advantage that allows much more surface area for the blades.
Great design from the NoCoDAF, looks like something you would see on airplane for sure. Also, the vase fan looks like it would be ok if you put it into one of those old school heatsinks where it was at the center and blew air outwards from a central point through cooling fins.
one thing i noticed with the vase. it looked like it was actually good at bringing air in. if you cut off a small bit of the buttom, rotated the blades a bit to bring in even more air and then plant it on top of a more traditional fan to move the air out of the center of the contraption it could probably be a decent cooler
It would be really cool to see the vase fan but with "wider" blades that extend further into the core. Perhaps they could even be curved in a way to allow more air to be pushed in the right direction. I honestly think that design has a lot more to offer and would love to see people do more with it. Also watching the vase fan pull the smoke was oddly beautiful in a way, I really liked it. Imagine having three of those fans (if you could improve the design to actually be more effective) mounted at the top of a case, that could look pretty damn cool.
Hello there, I have Legion 5 pro. I came across such a design. Before removing these, I researched the fan aerodynamics in detail but couldn't find it. In the end I couldn't stand it and took it apart and ran a few tests. It only gave me 2-3 degrees. I also didn't see any difference in the long run. I did tests before disassembly, after disassembly, and when reattached. When I plugged it back in and played CSGO, I got the same temperatures without unplugging it. In conclusion, we can say that it does not make any difference. But what compelled me to put them back on was the whistling sound from the fans after I took them off. There was a whistling at the lower revs, and a resonance and echo in the sound at the higher revs. When the revolutions of the right and left fans were different, it resonated as if two same music was turned on, 1 second apart. What I'm wondering is lenovo probably put this in for convenience. To avoid noise and during disassembly, the ratings gained are not high enough to be recorded. But how does it cool even though it is a part of it and what is the working logic of this type of fans? What is the Ayro dynamic structure? I'm really curious. How do they pull the air, is there a 3d modeling or a wind test? What is your opinion about this design? At first glance it looks like it's sabotaging the cooling :D Details are here ; www.reddit.com/r/LenovoLegion/comments/o01biu/can_legion_5_pro_cooling_be_improved/
Oh thank you, since you mentioned this so long ago, I've been waiting ( with baited breath) for this vase fan. I'm writing at the beginning of this, I hope it's in the top 25 by the end.
In honor of the NoCoDAF's brilliant performance, I think you should start including "1 / (Delta * Db)" ratios. This will rate fans by their ability to cool down proportional to how quiet they are. In other words, this would be the column you'd look for if you wanted the most silent build without thermal throttling.
Maybe for season 3 you could do a point system. So the best one of each episode is always the most rounded fan rather than the most efficient at cooling.
If you make an air-guide for the bottom of the vase-fan. Sort-a go 3-4 cm up from the bottom and block the air from moving out to the sides. Make skirts on the vase for the lowest 3-4 cm, that fits into the fan frame - I'm sure that would push the air through :D
the vase fan was actually pretty interesting. I'm amazed by how quiet it was and that curve toward the bottom actually moved quite a lot of air, even if it was mostly out. I wonder what would happen if you cut the end off and added a duct...
Bet that vase would do a lot better with a shroud around the lower end of the bulb and a set of vanes on the opposite side to clean up the exhaust flow.
The vase was fascinating. If your goal is to maximize intake (e.g. air filtration) it looks like it could be a viable design, assuming you could contain it on the back end and not lose to much pressure.
All the vase needs is an outer solid shell to direct that flow . On the lower bulb end, attached to the fan shroud. Maybe internal fins to guide flow. Im no expert but it looks like it has alot of potential
As a fan of the cheese grater fan, the vase also interests me. Would be interesting to see these as part of a system, the turbulence of the vase could theoretically eliminate or reduce "dead" pockets of low airflow.
Woww, I LOVE the shiny rainbowish color of that new filament! Thanks for making the vase fan. I'd like to see a regular vase that shape made with that filament but at the size of the blue one.
The vase fan is pretty similar to some horizontal turbines. Some attic cooling fans also feature a bulbous design meant to take horizontal air and force it down. The vase design intrigues me because there's lots of room for improvement, but I don't think it will be a top 10 contender. The blades need to terminate at the shroud and point inward more. The smoke test shows what's happening when it reaches the face of the motor cover (spews out everywhere). The NoCoDaf paid penalties to flow where it did not need to. It spun 5-10% faster than some of it's closest competitors yet generated less cooling (compared to the simplicity of uneven harmony). That nose cone, particularly, and the spoilers? at the fan blade edge are what I mean which were inertial losses and drag losses respectively. Not the best, certainly not the worst. I'd love to try my crack at it someday.
I like the appearance of the vase. well done. :) If the inside diameter was made much smaller on the larger parts, I bet it would kick butt with airflow.
What if the vase just needs a different method of installation? I wanna see the vase as the only fan in an APU build, with the neck of the vase shoved half way into case and the fan frame literally just being held by your iFixit magnifier-holder thing. The hole the fan goes in should line up with that support ring that's like a third of the way up, from the fan hub/ vase base.
Make a sleeve for the vase to direct air that at the base to the exhaust side! Maybe an inside cone can direct the airflow further from the inside. Maybe it will perform lots and lots better then!
I just want to say I understand next to nothing about computers or really much of this stuff, but I find it really interesting regardless. Great videos, that can be weirdly addicting, and I’ve been enjoying these fan showdowns since nearly the start
Replace bottom part of the vase with either empty space(3 pins just for holding it up, for free flow of the sucked in air) or have 3 thin fin fan blades there. I wonder how great It'd perform then. Hybrid between good fan blades and the top part that sucks in air towards it.
9:00 the smoke test for the vase looks interesting... it sort turn the air flow perpendicular to the the original flow. I am thinking the effect can be reverse?
with the starship....because it's wings were so small, it was actually the quietest of them all...thus I wonder if the blades that push the air...are a bit offset from the hub support and you have a smaller fans near the hub support to get low noise.

The NoCoDaf and even the vase are inspiring. I already submitted the Turbulence fan which you tested last episode (thank you by the way) but now have some ideas for a new design.
The vase is a spectacular exaust fan, we can see as it sucks the air but have no focus on pushing it, if modified on the area of the frame it can become a real contender to cool a CPU. And it's silent. And it's beautiful.
I think if the base of the vase was lower so it just fitted in the fan opening it wouldnt spit out so much air on the sides. I think if you would like compress the vase down in a way where it gets less long and more wide it would maybe keep the system cool enough
For the vase, create ducting around the outside fan casing (can't remember if it's convergent or divergent for pressure increase below speed of sound), and then as someone else said some internal Vanes to guide the airflow
I need a fan showdown AT LEAST every week or why the hell am I still living!?
@@notlayjeno6258 No.. I'm only interested in seeing fans and it's my sole purpose for living. This totally isn't a joke.
Great to see one of the reddit fans making it, design wise I'd say the atom is visually one of the best with its clean form and clear inspiration.
Anyway, so what are the odds off one of the geared multiple blade designs making it to a video? I'm biased to the original (given I designed it...) but there are a few now and I'd really like to see any of them tested.
Surely you will make it to appear in the video on the other hand your fan is amazing. I made a similar fan and it took me 6 months to get it working.
The way the vase was sucking in was quite wonderful.. I bet it would perform significantly better if there was a shroud around the frame of the fan to the point where the vase closes toward the hub of the fan. The design has a huge advantage that allows much more surface area for the blades.
Great design from the NoCoDAF, looks like something you would see on airplane for sure. Also, the vase fan looks like it would be ok if you put it into one of those old school heatsinks where it was at the center and blew air outwards from a central point through cooling fins.
one thing i noticed with the vase. it looked like it was actually good at bringing air in. if you cut off a small bit of the buttom, rotated the blades a bit to bring in even more air and then plant it on top of a more traditional fan to move the air out of the center of the contraption it could probably be a decent cooler
Loving that filament on those designs as well!
It would be really cool to see the vase fan but with "wider" blades that extend further into the core. Perhaps they could even be curved in a way to allow more air to be pushed in the right direction. I honestly think that design has a lot more to offer and would love to see people do more with it.
Also watching the vase fan pull the smoke was oddly beautiful in a way, I really liked it.
Imagine having three of those fans (if you could improve the design to actually be more effective) mounted at the top of a case, that could look pretty damn cool.
The smoke shots of the vase are the most beautiful thing I've seen here.
Hello there,
I have Legion 5 pro. I came across such a design. Before removing these, I researched the fan aerodynamics in detail but couldn't find it.
In the end I couldn't stand it and took it apart and ran a few tests. It only gave me 2-3 degrees. I also didn't see any difference in the long run. I did tests before disassembly, after disassembly, and when reattached. When I plugged it back in and played CSGO, I got the same temperatures without unplugging it.
In conclusion, we can say that it does not make any difference.
But what compelled me to put them back on was the whistling sound from the fans after I took them off. There was a whistling at the lower revs, and a resonance and echo in the sound at the higher revs. When the revolutions of the right and left fans were different, it resonated as if two same music was turned on, 1 second apart.
What I'm wondering is lenovo probably put this in for convenience. To avoid noise and during disassembly, the ratings gained are not high enough to be recorded. But how does it cool even though it is a part of it and what is the working logic of this type of fans? What is the Ayro dynamic structure? I'm really curious. How do they pull the air, is there a 3d modeling or a wind test?
What is your opinion about this design? At first glance it looks like it's sabotaging the cooling :D

Oh thank you, since you mentioned this so long ago, I've been waiting ( with baited breath) for this vase fan. I'm writing at the beginning of this, I hope it's in the top 25 by the end.
I love that low noise fan! I want one like that for my rig it's easily so noisy when I push it harder
In honor of the NoCoDAF's brilliant performance, I think you should start including "1 / (Delta * Db)" ratios. This will rate fans by their ability to cool down proportional to how quiet they are.
In other words, this would be the column you'd look for if you wanted the most silent build without thermal throttling.
Maybe for season 3 you could do a point system. So the best one of each episode is always the most rounded fan rather than the most efficient at cooling.
If you make an air-guide for the bottom of the vase-fan. Sort-a go 3-4 cm up from the bottom and block the air from moving out to the sides. Make skirts on the vase for the lowest 3-4 cm, that fits into the fan frame - I'm sure that would push the air through :D
the vase fan was actually pretty interesting. I'm amazed by how quiet it was and that curve toward the bottom actually moved quite a lot of air, even if it was mostly out. I wonder what would happen if you cut the end off and added a duct...
Bet that vase would do a lot better with a shroud around the lower end of the bulb and a set of vanes on the opposite side to clean up the exhaust flow.
The vase was fascinating. If your goal is to maximize intake (e.g. air filtration) it looks like it could be a viable design, assuming you could contain it on the back end and not lose to much pressure.
All the vase needs is an outer solid shell to direct that flow . On the lower bulb end, attached to the fan shroud. Maybe internal fins to guide flow. Im no expert but it looks like it has alot of potential
As a fan of the cheese grater fan, the vase also interests me. Would be interesting to see these as part of a system, the turbulence of the vase could theoretically eliminate or reduce "dead" pockets of low airflow.
I seriously think this is the best thing on UA-cam in a long time
Woww, I LOVE the shiny rainbowish color of that new filament! Thanks for making the vase fan. I'd like to see a regular vase that shape made with that filament but at the size of the blue one.
I had a great laugh at The Vase spinning on the motor. I'm amazed it moved as much smoke as it did!
The vase fan is pretty similar to some horizontal turbines. Some attic cooling fans also feature a bulbous design meant to take horizontal air and force it down. The vase design intrigues me because there's lots of room for improvement, but I don't think it will be a top 10 contender. The blades need to terminate at the shroud and point inward more. The smoke test shows what's happening when it reaches the face of the motor cover (spews out everywhere).
The NoCoDaf paid penalties to flow where it did not need to. It spun 5-10% faster than some of it's closest competitors yet generated less cooling (compared to the simplicity of uneven harmony). That nose cone, particularly, and the spoilers? at the fan blade edge are what I mean which were inertial losses and drag losses respectively. Not the best, certainly not the worst.
I'd love to try my crack at it someday.
I like the appearance of the vase. well done. :) If the inside diameter was made much smaller on the larger parts, I bet it would kick butt with airflow.
What if the vase just needs a different method of installation? I wanna see the vase as the only fan in an APU build, with the neck of the vase shoved half way into case and the fan frame literally just being held by your iFixit magnifier-holder thing. The hole the fan goes in should line up with that support ring that's like a third of the way up, from the fan hub/ vase base.
Standing still the vase was a thing of beauty but to see how it moved the mist even better.
Make a sleeve for the vase to direct air that at the base to the exhaust side! Maybe an inside cone can direct the airflow further from the inside. Maybe it will perform lots and lots better then!
3:45 pronouncing Davide (Duh-veed) as dah-vi-day...
Nailed it.
the vase looks like a great design for sucking air. with a few tweaks it can be an innovative product to be used for suction... like fumes or gases.
I just want to say I understand next to nothing about computers or really much of this stuff, but I find it really interesting regardless. Great videos, that can be weirdly addicting, and I’ve been enjoying these fan showdowns since nearly the start
9:00 seems like the vase could work reverse or something similar.
That vase would be perfect for smoking up the frame for photography use for sure!
And the starship totally needs longer Finns
If you add a filter and a fragrance to the vase fan it can make for a very aesthetically pleasing air filter and freshener.
Replace bottom part of the vase with either empty space(3 pins just for holding it up, for free flow of the sucked in air) or have 3 thin fin fan blades there. I wonder how great It'd perform then. Hybrid between good fan blades and the top part that sucks in air towards it.
9:00 the smoke test for the vase looks interesting... it sort turn the air flow perpendicular to the the original flow.
I am thinking the effect can be reverse?
dude the smoke going thru the fan was epic... a loop with different shots and colored smoke would be fire
the vase flings air out below the widest part; it needs a shroud or something at the bottom
Very good PLA colors! Love the music on this one!
love this series, need two episodes a week!
Can't print fast all time, it will s sad. Also test is longer to do. Maybe he could show us a time lapse of his making of one episode.
with the starship....because it's wings were so small, it was actually the quietest of them all...thus I wonder if the blades that push the air...are a bit offset from the hub support and you have a smaller fans near the hub support to get low noise.
