I’d like to see a retest of the top 10 fans. Chance to see how accurate/repeatable the tests are
I'll second this... a best of the best head to head .
You’re killing me with the davide pronunciation 😩 say it divide with an A Jesus 😂
@@matthewbernard4152 you wot m8?
@@josephlondon8188 TH-cam was probably being dumb with its new comment section and put a reply to the video within a comment thread.
I'd like to see the dick fan all the way back from the early episodes to be tested again
Aero engineer: I made this great fan with super low sound output
Random guy: so anyways I turned this vase into a fan
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
Haha
@@DragonstarFighter yeah printing that on a resin printer would probably make more acoustically pleasing to the ear.
The vase was so quiet because it didn't really move air lol
Wish the engineer had made something as wacky as the vase.
Can you add a decibel column to the big spreadsheet at the end? It would be interesting to compare them all at a glance.
This ^^^^
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.

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 am happy to have been chosen and would like to thank everyone who rated my atom fan on reddit.
Dude that fan made me go ooooooh, it’s such a good looking fan. Great job
It would go really good with a fallout themed build
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
Bro you should make a fan with GEAR to spin at higher RPM
How do you pronounce Davide? da-vid, da-veed, day-vide(v-eyed), dav-vide or something else.
the nocodef could need a resin reprint to do justice to the small features
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.
@@WarrenGarabrandt but the shapes on that fan were so precise and they were messed up in the print
@@stutterpunk9573 I'm with you. I want to see it do better in resin.
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.
Yeah the print quality looked too low for how precise that fan needed it to be
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 bet that if you cut off the bottom of the vase so that the air was flung into the pc instead of outside it would do better
Definitely need to use inside space to smh force airflow to the back
an internal turbine was my first thought, it would add stability and suction
Just yeah cut down the base and add a conventional fan
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
Vase fan acquired. Next step: vase with flowers
Fan with flowers
I hear flower power is strong.
HAHAHAHA
Then with three of them (with flowers) hanging of the front or a gaming rig for some real world fun.
What about the face-palming picard?
I really appreciate the fan's picture in the bottom left. Good add, totally improved things.
I feel like that vase fan could really push some air if it gets tweaked at the bottom, awesome episode as always
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 was thinking the same thing
Vase 2.0 lets go!
Would be a nice fan to stick out the top of a pc case... granted that it won't be in the way of something
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.
You should add Decibels to the spreadsheet! Also would love a sound comparison of the top fans.
Idk that doesn't consider the (tone?) Which can be also very important
@@walkinmn I absolutely agree, tone is probably more important to me, but that's why I said to do a sound comparison of the top fans too!
@@walkinmn True, but having it included would be better than not at all which is where it's at now.
He has problems with the sound testing. The data is useless.
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.
It would be cool to see a ranking of decibels per delta: how many decibels it takes to reduce the temperature by 1°.
Do the maths and we can name the unit an Alex 😁
@@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?
@@alexp974 neat idea!
I think the NOCODAF could really use some post processing, the edges were a bit funky and it might benefit from some sandpaper
Symetrical leading edges, not asymetrical would help
I'd rather it got printed with resin. It really needs the precision, and filament doesn't get to be precise enough.
@@shadowopsairman1583 Symetrical blades are what a siren has. Balanced asymetry should be quieter. Your brain picks up the repeating pattern.
Thanks for featuring the vase! Hope you guys liked it :)
@@notlayjeno6258 I'll post somthing on the reddit page later today or tomorrow. I kinda made some fans for the inside of the vase.
The vase fan looks like it would be good at keeping your VRMs cool lol..
lol put it on your CPU in a desktop style case (as opposed to tower) and add some fake flowers in it too :D
Could you do a collab with gamernexus when they get their fan testing machine?
PLEASE!
Just commented the same thing!
I'd wait until April Fool's day and send them a bunch of modified fans in noctua brown, along with real notcuas to camouflaged the 3D printed ones.
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
Number 1 fan literally designed by an aerospace engineer with lots of thought put into it.
Entire comments section: "Vase fan go brrr!!"
Nah
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
Honestly?
The vase did better than I expected
it failed....
@@nudl3Zz it moved air from front to back
@@nudl3Zz tbf, it didn't crash the pc like some others
All the vase needs is a "flat" base, because it's drawing in plenty of air...maybe halve the number of vertical fins too...
a graph of cooling vs db level could really show which one is the best of both the worlds tbh..
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.
Next goal: make a vase-like fan that actually works without throttling
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.
The atom one would look so cool if you would use see through blades that only have a colored rim, so it really looks like the atom model
the rutherford model does look cool. especially if you made it rgb so the edges glow. I wonder how the Thomson model, would look...
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
@@notlayjeno6258 these are 140s?
The vase and smoke looked like Jeannie's lamp from "I Dream of Jeannie" in reverse.
I was hearing Groove is in the Heart, but I like your version better
The fan from the aerospace engineer is probably only loud because of bad printing
The vase would be fun in a case, with the fan running at 5V. so it spins around slowly
Someone develop a machine learning algorithm that creates fan shapes and tests them. Let the AI figure out optimal design!
there is
@@jsihavealotofplaylists Where?
i was surprised and impressed by the vase
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 could see Major Hardware having Noctuas in his bathroom ceiling.
just waiting for Noctua to send him a ceiling fan sized fan :)
The vase surprised me with the smoke show! I was not expecting any air to be pulled
the Atom fan exists.....
rainier wolfcastle: "Up and at them"
up and at'em
@@keith4430 "UP AND AT THEM!" haha
The maker of NOCODAF should have looked up the "acoustic metamaterial" that uses destructive wave interference to eliminate sound.
pretty sure the destructive interference is happening from the irregular edges on the fins
It’s always curiously satisfying watching this series. Thank You for continuing with this.
Seems like you’re in need of a fan blade balancer similar to what they have for car tires!
Does watching all of these make us fanaddicts?
(The double entendre makes it even more apt).
Fanny porn?
Fanatics?
@@wildtangent6890 Fans?
That filament is gorgeous btw
The vase seems like a really good device for keeping the room cool in the summer since it spreads air in a lot of directions
Loving that filament on those designs as well!
If the vase was smooth on the outside and veined inside past the neck, it might really blow.
Im going to say "that's what she said" so you don't have to deal it everyone spamming it in your comment.
@@that1nerdyblackgirl736 That’s what she said
Oh I think this vase fan already blows...
@@NorthernSeaWitch no, it sucks, because it's an impeller competing with a bunch of propellers
@@l.c.8475 r/woooosh
It's pronounced vase not vase. ;)
You mean vasé?
I think the vas was the most satisfying to watch with the smoke test out of all of them.
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.
The Vase Needs a micro-Tire balancer LoL 🤣
🥇 First Comment 🥇
*6th Comment
For the record I’m a full grown man crying about pretty fans 😭. This is the most manly thing I’ve ever done.
Gonna validate your manhood as well, this is beautiful
I seriously think this is the best thing on TH-cam in a long time
@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!! :)
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.
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
8:45 that vase soaking the smoke and spitting it out is TRIPPY
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 just binged like this whole series. I absolutely love it and I totally want the biohazard fan lmao
Please never stop 😂
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.
The smoke shots of the vase are the most beautiful thing I've seen here.
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.
Standing still the vase was a thing of beauty but to see how it moved the mist even better.
Coolest vase I've ever seen!
8:18 The majestic vase spinning with the base duct taped to the desk. Amazing.
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.
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.
If you add a filter and a fragrance to the vase fan it can make for a very aesthetically pleasing air filter and freshener.
I had a great laugh at The Vase spinning on the motor. I'm amazed it moved as much smoke as it did!
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.
Excellent as always! Love these
That vase looks so cool spinning. I love that there is a channel that does this stuff :)
Mad Science that no one in the corporate world gives a Shizz about LoL
Very good PLA colors! Love the music on this one!
the vase flings air out below the widest part; it needs a shroud or something at the bottom
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.
I hope it becomes a weekly thing because I live seeing the ideas ppl come up with and how they do in the tests I want to make one but I don't know how to
I love that low noise fan! I want one like that for my rig it's easily so noisy when I push it harder
The green one is a really good reference to a fan that does suck at all. Sometimes it looks like the smoke it like being pushes through rather then sucked through
I think that smoke test for the vase is one of, if not the best, smoke test to date. That was cool to watch. I bet with the right internal structure, not just hollow like that one, it would be an air moving beast
dude the smoke going thru the fan was epic... a loop with different shots and colored smoke would be fire
That vase has potential. The filament you chose was awesome
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
Very nice sir, appreciate the hard work!
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.
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
My gummie hit right before the vase started turning. Keep up the good work. 😎
Dude you're the best!!! hahaha a Vase this made my morning lol
I feel like Steve from Gamers Nexus would appreciate your work lol
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.
Be interesting to see an inverse of the vase fan.
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.
Who woulda thunk. Expert production, fun presentation, and suddenly I care about computer fans. Great idea.
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
I’ve always wondered if you could use this exact shape with a solid outer wall and extending the blades further inward.
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.
I love the video of the NoCoDAF pushing air, soo cool
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.
That vase was really effective at pulling in air. I would love to see some modifications made to get it to push air as effectively as it pulls it.
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.
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...
the starship made me suprise how much can it flow.
the atom was piece of art, as beautifull that can massage the eyes.
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.
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.
I wonder if you could build an acrylic/transparent box that resembles a PC tower, and you could drill a hole on the opposite end that you pump the smoke in to simulate how these fans pull air out as a hypothetical. I think it would more represent the functionality of a PC fan test.
Woah I love the Atom! ⚛
that filament made a sick looking print on that vase fan
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
