- เผยแพร่เมื่อ 24 มิ.ย. 2024
- We have seen so many different fans on the fan showdown it boggles the mind, however just when you think you have seen every single fan in the known universe the fan showdown throws you a new one. Today I test 4 fans that are unlike any we have seen before. Let’s continue our journey to find the coolest fan design on the planet.

I'm impressed by how that alligator clip setup handled the mono.
Roach clip
Those are called helping hands. They are typically used for soldering wires together in line and other things.
Just drill a hole say the outer edge and fill it with weights- takes a little work but will balance it
@@vikmanphotography7984 Or just drill material out of the heavier side. That's how I balance flywheels.
@@SwervingLemon I feel like only removing material could require removing too much material as to impact the design of the fan but if not- fair point.
that is one satisfying pop when you take the mono off
Yup.
i almost jizzzed
@@wphanoo lmao
That retriever puts the golden in golden retriever. *Literally glowing*
haha he is isnt he? such a cute little boy
Retrievers are sun seekers, they will always find the one spot that has a sun beam and lay right in it. As such they frequently glow =P
He may have a side quest for him...
just watching hi sleep is sooo relaxing
He 'literally' isn't but he's definitely a good boi.
On the smoke test you showed each fan starting up some episodes ago, I think that looked really cool and it also made it easy to see which one was being tested, can be hard to remember which was named what when you've only seen them once.
I love this series!
Would also be cool to see the blades engage in the RFB.
Yea I wish he would still do this
Agreed lost track of which was which. Except mono
I support this.
Adding a small picture of the blades in the corner of the screen with the name of it during tests would be great.
Personnaly I don't even care about these tests but there is probably some people that would like to have this...
Is it just me or did cooper looked annoyed as f...k
"Great, my human is talking to himself again"...
I better get my treat after he stops talking to himself
I'm fairly certain all dog owners know that look... that unique combination of "ugh, what are you doing THIS time?" and "*sigh*, I hope I get a treat for putting up with this."
What, you mean you guys aren't all here to see Cooper? Some fan guy keeps showing up in Coop's videos.
Idea: Keep a picture of the fan in the corner when you are talking about it. I can't keep the names straight when you are talking
I was just thinking this lol
if they just showed each fan starting up so you could see it before/while the smoke test is going youd know which fan it is and get to watch it work.
He could even do it as narrative dialogue over b-roll, changing the music as he goes to match the fan like how I used to use a sound box for sound effects during conversation at parties... Mike when someone says something really serious and you add a fart sound lol 😂
PLEASEE
@@TheCollectiveHexagon he does this in the future videos. he listens
I can't believe how hooked I am with a series about FANS.
funny how anything can become interesting when people can just all participate in creating something good instead of comparing products from corporations
You're a fan?
@@2993LP fan fan

@@2993LP I'd say the series is fantastic!
Him: At the beginning of the video: Look at how well the color of this filament matches the fan.

Not resin dude, that's filament.
Sorry to be that guy.
@@Litl_Skitl Fixed.
8:24 The SWAG fan is actually pretty clever - can see the smoke going through the slits in the blades - and the air flow out the back is impressive
It somehow manages to keep the airflow central rather than dispersing it away from the fan. Don't know if that's because of the slits or if it would still do that without them though.
I feel like there's finally been a concept that's proven itself to the point that it needs further iterations.
man i wish i'd been keeping up with this series earlier
The SWAG's slits to let a small amount of air through to the upper side of the airfoil are not just aesthetic, but necessary in its design.
In aircraft, these intentional leaks are used to prevent stalling when the plane's angle of attack is too great, which drastically reduces lift while drastically increasing drag. In this fan, introducing these leaks allows for a far more aggressive blade angle without stalling, which would drastically decrease flow rate and speed. From the side shot of the SWAG at 3:40, it has quite an extreme blade angle indeed!
Keeping the flow central is mostly something else though. Because fans rotate, air passing through them gets thrown away from the center as it is pushed through the fan due to centrifugal acceleration. Simply put, the air touching the fan gets swung away from the middle. This effect is generally not desired since air moving away from the center means energy is being wasted on accelerating air away from the center and since it means less airflow at whatever the fan is pointing at.
Fans usually compensate for this by giving each blade a reverse sweep, such that the curve of the blade as viewed head-on scoops air back toward the center like a scythe. Even the SWAG has a small sweep like this. The slits however _may_ also help a little bit by interrupting this axial flow away from the center, creating a trap on the bottom side that air falls into and a wall of leaking air on top that blocks air from crossing the slit.
Fan Showdown randomly appeared in my recommended a few months ago and now its a show I look forward to every week. Love these videos!
same story here!
Saaaaame
That filament you used today looks so much like wood at the right angles. Looks great
i was thinking the same thing, especially the Monoe
I wonder how balanced the monoe would be if it was resin printed, id really like to see that ones performance when properly balanced.
I don't think balancing it will affect air flow. It might make it quieter. It just needs some careful sanding to balance it.
@@seitenryu6844 With better balance it should spin faster and thus create better airflow, right?
@@sevret313 Not by much. Also, it wasn't even ranked the best in this small group, so I don't think you'll get much out of it. Granted, it's only a single blade. Would be cool to see it with more blades.
I think a double would do it, and it will be balanced, would love to see how it will perform
@@seitenryu6844 Single blades are ment to run at twice the RPM
you should give us some close up panning shots of the wall of fame their whenever somebody is dethroned.
Seconded!
The Monoe test gave me a good chuckle xD
Best co-host on youtube 😂 Such a good boy
Yes indeed!
ETA was also a good cohost on business blaze RIP ETA
Yay, best show to watch before bed
Also awsome seening the cfm info
True
Maybe a black background with like a measuring stick for the smoke sideview would allow us to see some clear patterns and speeds to amplify our collective autism
_measurements to appease the hivemind
data to please the hoard_
Professional smoke testing is usually done with a wand that has a bunch of holes in it, so you get lines of parallel smoke traveling forward. It's the visualization that you often see on cars in wind tunnels.
@@louisvaught2495 laminar flowww
Maybe introduce a short blotch of coloured smoke to as a point to follow?
The Swag had the cleanest / least turbulent flow in and out of the fan I think I have seen so far on this show.
the monoe just made me giggle endlessly. It just slowly walks away
It reminded me of a 1981 children book by the great Ephraim Kishon (prolific author, Oscar Nominee and two time Golden Globe winner director and film writer) about a travelling (unbalanced) washing machine that goes on adventure :-)
@@Mrdardas99 I know that book, my gosh that brings back old memories
@@Mrdardas99 excuse but did you just say an unbalanced washing machine going on an adventure
I have no business caring about fans or 3d printing but I look forward to every episode. You do a good job and it shows.
Side view is👌
Who else is interested in seeing the cross section of the smoke pattern?
7:56 The smoke actually prefers to go AROUND the fan rather than through it, lmao
Maybe you could use a bit of dremel on the mono, I really want to see it working once balanced
Same !
Yes, right, I'm pretty sure the fact that it's unbalanced makes it work a lot worse
prob could be fixed with a resin printer
@@Akio4800 Honestly they all should be made out of resin, it seems higher quality. For something as precise as Aerodynamics, it seems useful.
Do the monoe justice and balance it. We'd like to see some test with that fan finally not throttling
Thanks for including cfm measurments...a strong correlation to cooling efficiency!
A pressure/flow graph would be even better, but I reckon that takes A LOT of work
To the WID and the WID maker. MY inner voice tells me that if you had also small blades on the inner side.. around the core diameter.. and a circular gap between the inner and outer blades....then it could be MUCH more effective 😊
Ooh, it could be 7 blades on the inside and 13 blades on the outside, for the perfect combination of good and bad luck (also to reduce noise via irregular fan blades.)
I feel like the swag just won bc it's the most ~fan~ out of all the fans in the fan showdown. It's not trying to be special, it's just trying to be fan. And it succeeded.
That smoke test with monoe was great 😂
The WID looks great, maybe as a case fan, and if it was a bit quieter
11:30 that look in Cooper's eyes of "did I do bad?" awww
Hell yeah! I've binged your playlist with Fan Showdown, so I was looking forward to a new episode! :)
The Monoe smoke test was so flipping funny, omg, the silliness caught me off guard.
Looked like it was beating the air thru it... and beating up everything else it can reach as well.
You did an amazing job of photography and composition IMHO here! Loved it and the content as well. 🔥🔥
I like the side view. In terms of seeing how the air gets dispersed behind the fan. Cause it tells me how it might channel the air across your PC parts. And in this video I like the SWAG and RFB.
That swag just a fine tweak for acoustics and is gold...
It would be interesting to see the RFB and the Monoe start up and run in slow motion. I'm curious if the Monoe's counterweight is flexing it's supports causing the imbalance.
Yeah!
I was hoping slow motion of RFB start up
Jimmy: puts holes in his fan blades.
Jimmy: Get's first place. "All according to Keikaku" (Translator's note: Keikaku means plan)
@@635574 They fixed it.
The blade design on the Monoe is cool. I’d like to see a three blade version.
Man the show as come such a long way! Great fans this round! Loved this!
I’d really love a static image of the fan during each smoke test, sometimes hard to distinguish, and the names are always Wild lmao.
Man the quality of the series compared to season 1.
Well done man we can see you've learn alot about camera angles and lighting and what not.
Making the series more enjoyable to watch with every episode thanks man!
Just found this series... it's awesome! Great job!
Nice! I've got a suggestion, can you make a seperate series reviewing the top 5 consumer fans out there? Just a thought, keep doing the great jobbb!!!
wow. your production quality went up a lot! since i watched one of your videos last (i think around christmas or sth like that)
nice ♥
Welcome back
Been missing a new episode! Awesome episode
Great video quality. I can see, you try to improve them with every episode and it is working! Keep it up!
Why do I have a harder time resisting these videos the more I watch? Fluid dynamics are fascinating... you’re damn hilarious and charismatic too 😜
Always a good day when a new fan show down is uploaded
Your videos are higher quality than 90% better of TH-cam you should have millions of subs too. Keep growing man! Love the videos
That dog made me subscribe :) love your work!
Great timing, I literally just opened youtube
Same😂
Similar action I did . Meow. Got to see them fans!
This is a great series and have thoroughly enjoyed watching even though I am likely not going to design a fan myself. The front and side views of the smoke test is great to have. I put the playback speed on slow to watch the movement in front and as the smoke passes through the fan and is expelled. Very interesting how the different fan styles move the air through and then discharge in different patterns.
Someone suggested a scaled background so we could determine speeds. That is a great idea!!
Thanks for your time and efforts towards such an educational and entertaining series.
Dude we often can't tell which fan is which during the smoke test without going back and rewatching to see what each one was called (i generally don't remember cos i don't care what they're called), can you have a pic of what the fan is during or something
Agreed, once they’re already spinning as shown, they all blur together: seems like watching TV with all the people hiding their mouths while speaking, with no subtitles, on mute. Well, you know they’re speaking, but what?
keep up the awesome Channel dude !!
Just finished your 5x 40mm fan vs A12x25, clicked TH-cam and boom! New Fan Showdown episode baby!
If you were able to do some high speed recording for slow motion footage, that would be very interesting. Would love to see some ultra slow motion of the smoke test, and that RFB spooling up.
The ptoblem with the mono is that it isn't dynamically ballanced. If you have a stick with a small weight far out on the left side and a bigger weight on the right side near the center, it will be ballanced when still. But when you spin it, the small weight moves a lot faster and the balance moves to the left side. Static ballancing is better than none, but dynamic is the only way you can achieve a perfect balance.
Eagerly watch these hoping to see my fan. :P
Although, seeing all the other ideas is really fun, too!
Side view on the smoke test is amazing!
Love the side view! I feel like it gives a new perspective towards the “air flow efficiency”!
I love your channel and can't wait for your next upload but.. 0:03 that stain on the couch on the right is atrocious !!! LMAO
Blame cooper for that wet nose of his
One reason people have so much trouble with a monoblade is they need to take into account the force the blade is exerting on the air and the greater friction the blade side has with the air. I might suggest adding tiny horizontal fins that would create drag equivalent to the fan blade
It doesn't matter how perfect the center of mass is if there is a significant force acting unevenly on the fan.
The most enthusiastic co-host ever 😁
i looked at the dog for the entire time he was on screen. what a good boy. the goodest of boys
Looks like wood, so cool. Someone should show this to Wintergatan
Shhh. He doesn't need yet ANOTHER specialized tool.
Joking aside, most of his parts need the robustness of metal and wood, so plastic is probably a no go. Maybe when technology improves in 5 years plastic/resin might be more viable.
@@r3dp9 Agreed. He is using plastic on the new marble divider though. He already developed the cad skills necessary for the job, I think he would come up with something interesting for the marble funnels.
The sideview rly makes that smoketest so satisfaying
Yay another episode :D some great contenders this time.
What I like about the side view is it has a better view of how smoke comes out the back, which I find more interesting because it shows a lot more of the fan characteristics. The size of the cone/spread, the speed of the air, if flow is choppy or not, etc.
It’s also just a nice shot.
me: watching the spot of sun slowly crawl down Coopers beautiful dog body, what a great boy.
Fun fact: turbo fan jet engines have similar jointed blades so at high RPMs the blades can move to the most ideal and efficient position. However they have much less play than those fans.
The Swag has epic CFM 🌀
You should have a little mount for the fans. I’m pretty sure you holding down the moon helped a lot in reducing noise. A surprising amount of noise from a fan comes from the material vibrating again whatever it’s attached to so if you could maybe reduce the vibrations you could get a more accurate noise readout?
Really liking that side view, can see the airflow out the back. Hmm dispersion cone? The mono had two patterns to it, guess the counterweight was pushing air too.
oh man, thumbs up for the old oil commercial cut away, "Now That's thinking with your dip stick Jimmy!" loved those as a kid >XD
Awesome video as usual.
Also see the dog steal the show, by just chilling there doing nothing. hahahahaha
Gotta love the 4D chess commentary. Love the fan showdowns.
That good boy deserves lots of scarches! How can you sit next to a dog without constantly petting it?
Fantastic stuff Great Way to fermilerise with consitsent test efforts !!
The spread of smoke from the WID fan was amazing, it absolutely scattered the air going through it.
Notice the CFM reading in the SWAG? Of course it was going to crush.
I have a suggestion for your next fan showdown, could we get some shots of the fan facing downwards blowing upwards and you shooting the smoke under it to see its sucking power?
Currently with the smoke having initial velocity towards the fan its a little bit harder to see how much air the fan is actually moving vs the air that was already moving to begin with.
Love the new setup!
the side view was indeed a nice idea. the shark teeth seemed to have a bad airflow for cooling but really effective at spreading and filling the space which could make it useful for the PC case's intake fans
I like the fan showdown and it's odd I don't build computers and have never made anything for 3d printing but I find it fun to watch please keep it up
This series is great and I love that dog
Forgot how much I liked this series! Sort of stopped watching this series after I submitted five different fans (each taking 3+ hours to make) and none were selected.
it's easy to balance stuff, put it sideways, let the heavy side fall, remove a tiny bit of material and then put the heavy side to the left or right, if it falls slower, keep removing material (or in fact adding material to the other side)
I thought the RFB had the nicest sound and impressive performance. Really great idea
RFB just sounded like a normal noctua lol
You're the reason I bought a 3d printer. I love the videos and some education! Your co-host is brilliant!!
This is inspiring so many projects for me
Just curious, would there be any way to fix the imperfections on the blades. I saw on the WID the blades had very visible print lines. Does that even make a difference in say like turbulance or something alone those lines? Awesome video dude!
The side view is really cool, you can see the angle/spread of output flow.
That progressive airfoil really helped deliver more static pressure I bet. It looked really efficient in the smoke test. That side view made it immediately apparent which fans were spending most of their energy pushing air straight out the back of the fan, and how many were wasting most of their energy spinning the air around so it flies out to the side as soon as the fan isn't containing it. I'm betting low helicity and high velocity equates to better performance in a radiator cooling test since the air encounters the least resistance travelling in a straight line perpendicular to the radiator, so the more the fan is making air move that way, the better it will do.
I LOVE THE SIDE VIEW!!!!
Actually i am here for the sound, so i’d love to have the analyzer and frequency spectogram!
i appreciate the music choices in this video
This is getting good!
It would be interesting if you fixed the Fan to an clear acrylic sheet with a cutout for the smoke test. That way you dont have anything flowing back or bypassing the fan, and would see just what the fan does. I think 4-5 Inches around the fan would be enough to stop anything from bypassing or flowing back to the intake side. Great channel btw, I love your content.
That filament looks awesome, it's like the fans were carved out of wood! Wow!
Great smoke test this time such a solid 👌 stream. Are you using a long tube now? Any updates to the smoke setup?
The Swag fan reminded me of what we learned in swim class. If you separate your fingers just a little while pushing through the water, you get more force on the water. I am betting this is the same that is happening with the fan.
Now those gaps need to be widened until the delta starts rising again. I will bet it can be lowered into 53's and maybe 52's
Side view is very good and shows airflow going out quite nice.
I'm more impressed that your mount held the mono, then how the mono did lol
