Worlds most powerful RGB PC fan 

If your gearbox melted down... maybe you need to cool it somehow? You could build a fan for that! 💖

i don't know if i'm supposed to be impressed or horrified with the fact that a propeller that unbalanced didn't blow up with full send

*Deadly spinning RGB fan* My brain : Do it, put your hand in there

This was bloody amazing! Cheers for the shoutout to Major Hardware and the fan showdown; I would love to see him test this one in his wind tunnel. That was quite an impressive build that really shows off just how much you can do with 3D printed parts.

Everyone knows RGB adds +2 proficiency to Dexterity checks, lol. Love the build! - Perry

What a fun project! Taking out the chips was hilarious!

This is great! You know that after referencing the Major Hardware fan showdown, you have to make a some of the cool and really well performing designs for this monster.

So awesome! Well done! I'm honestly surprised the 3D printed gearbox lasted as long as it did given the torque on that beastmode motor you put on there.

I build and fly quadcopters, but they only run 5" props and I'm terrified to be anywhere near the thing at half throttle with props on. That beast of yours had me clinching the whole time you were sitting in front of it o.O!

If you want fast bearings without them being so quick to die once you remove all the grease, use a couple of drops of gear oil on them instead of WD40.

I would've used the guts of an ordinary box fan and just essentially created a more fun case around that motor and control system. And with that hub design of yours, you could experiment with fan blade designs and get way more performance out of an off the shelf box fan then they come with, I bet. Could be a pretty fun alternate fan showdown lol

That was GREAT entertainment. It's not often that I actually laugh at a video. But this was simultaneously fkn funny, technologically impressive, had some making, some 3d printing, and some future nostalgia embedded to remember the damn rain and floods years down the track. Bravo Angus!

This needs to get into the hands of the guys at Gamers Nexus. Would be a perfect fun project for the new test rig and a unique collaboration

I feel like the friction from the grease in the bearings is negligible when you're using a 1500 watt motor. Yes, when you're flicking it with your finger it stops quickly. But when being driven with even a few watts I can't imagine the drag is even noticeable.

Really cool build. It makes great "thrust" and has an awesome design. As an aerospace engineer, however, this is terrifying. There will be a speed at which the hub can no longer hold the outward force generated by the blades. Additionally, the blades themselves are only held together by the layer to layer adheasion / fusion of the plastic. Those jet engines you referenced have 75 years of design experience and testing holding them together.

AWESOME PC fan, Angus! Regarding Microcenter, I live in the Atlanta metro area and have two locations within an hour of me. I always feel bad for folks when I hear that they aren't near one, or anything like it. Sure, online stores are great, but there's just something about walking around a place like that. It's a blessing and a curse, of course. Like the home improvement stores... I can't tell you how many times I've gone in for one little thing, and left with a much fuller cart and lighter wallet than I'd initially intended. :)

The $100 Ender3 (even if it's just a sponsored event) is honestly a damn good offer. Like, sure, it's not exactly state of the art anymore, but I'd say it's what I'd recommend anybody who wants to get started and isn't quite confident enough to go for a Prusa. Also, as for the main focus of the video, I just love seeing all the design work that's gone into this, especially at that scale. I mean, those M10 inserts are just... chonky.

Well... THAT is certainly less quiet than a Noctua fan... Great job, Angus!

Awesome design, it looks perfect! A toothed belt drive rather than spur gears might be worth a go, it would be a lot quieter if nothing else.

I didn't know MicroCenter wasn't even in Australia and they still wanted to sponsor you! Your maker skills are clearly world-renown, that thing looked it it was going to levitate when you first turned it on haha. I expect nothing less than a 3D printed jet engine next time!

I genuinely laughed out loud when the PC blew over 🤣

That is so legit. I love the blade dovetail fastening.

I love how you showed the Fan Showdown from Major Hardware, bravo! ;D

How cool of Micro Center for sponsoring this video! That fan is terrifying! I LOVE IT! I legit might have to use that coupon!

Spent the whole video waiting to see if you'd mention the Fan Showdown, this would make an awesome collab topic ! :) Oh and a real use case for the fan : depending on the CFM capabilities you manage to get out of it, it might do for a pretty awesome table windTunnel fan, compared to stacks of small PC fans like we sometimes see ;)

Don't just get a power meter - get an anemometer too! Show is those wind speed measurements! Also if you're reprinting the gears (why wouldn't you, lol), would helical make a difference? Or printing in resin? Helical would be quieter but not sure if the shear forces would rip it apart on an FDM print, hence the resin suggestion. Fantastic job on the 500mm Coarse-Air!

It was the maniacal laugh for me! The sheer enthusiasm for this project is awesome!

One of the BEST videos yet! I totally loved it. This is what pushes the 3D printing community forwards!!

Angus, that was incredible .... Oh yeah, insane too lol. I'm stunned that the blades held up to the centrifugal force, I was convinced those would fail first. Great work 👍👌

Brilliant work Angus, although a custom printed PC case that integrates this monster is now inevitably in your future…. Linus are you watching?

1:16 - I could just watch those printers on endless loop whilst listening to your commentary... they're so mesmerising.

RU-vid needs a double like button, just for things like this! Angus you legend! Thank you for making all the files available as well, extra bonus points for that. After the obvious bonus for the "I'm gonna step away and full send it" segment. 😂👍

I say replace the receiver with a microcontroller that can output tach signal and take in standard pc fan PWM control signals and control the speed. Then you can hook this to a PC motherboard and use it as a case fan.

I'm curious to see the wind speed it puts out. Maybe get one of those meters to measure it? I'm more interested in the fan's output power than the power consumption. I wonder if there is a way you could measure CFMs? Maybe attach it to a big plastic bag and see how long it takes to fill it?

I like that you included the Major Hardware video at 11:10. Wouldn't be a 3D printed case fan video without him. :D

That is so cool!!! And you just sharing the files is really very cool too!

One of the coolest 3D prints I have ever see!Also love the major hardware shoutout! 🍻 great work

I am happy every time I see a add for Microcenter every time I go into one I am impressed. They are too far away but that's the only bad thing to have to say. Just being to be able to see and buy filament and other 3d printer parts without needing to wait is amazing.

Sir, you are truly a mad scientist, genius engineer! That is the best looking whole-house-fan I have ever seen. What a cool (breezy) and fun project. Glad you just HAD to have one. Thanks for sharing your brilliance. That video was hilarious and informational at the same time. Good job!

Yes, that is indeed frightening. I'm impressed the blades didn't leave for a better (and drier) place. Great build!

You could say it’s your biggest fan (haha I’m bad at puns)

Epic build!

Wow, have you found a new purpose in your work? There was so much energy in this video. I love it. Glad to have you back, sort of... Keep it up :-)

Looks awesome, I can't wait to see the size of the PC case your gonna fit it in... But seriously you should build a PC with this as the main case fan just for giggles.

Hahahahaha dude yer wildn out over there. Love this!

I would love to have one of these beasts but a $20 box fan from the local dollar store still does a better job while also being much more safe to use.

That was the best video I've watched in a long time!! Love it. Now you have to set it up for part cooling on your new $99 Ender 3 from Microcenter.

Dude that was sick. You keep making stuff like that and I’d pay a subscription to watch!

Having nearly sliced my finger off with a model plane prop before, there's no way in hell I would have been sitting that close to such an imbalanced fan blade spinning that fast. Didn't really expect that from you considering how much emphasis you put on safety on your channel. Glad to see nothing catastrophic happened. 1500w is a ton of power. Please be a little more careful next time. The rotational energy in that thing can cause some serious damage. Awesome build though, that's for sure!

Got to be the greatest fan ever made! I wonder if Gamers Nexus can test one or is the new fan tester not big enough 🤔

Love this build. I'm a huge fan of the tech space and it's what brought my attention to 3d printing. Always love to see clashes between the two.

Hey sir, Ive loved your videos for a while now and they really have helped me. Im a fair bit older than you and I remember the very early days of 3d printing and have watched its evolution over the years. Somehow I got left behind with my CNC machine, but are getting up to speed now thanks to you. What I would like to see is a video of the pros and cons of the different 3d file types. OBJ vs STL vs 3mf, etc. Have you already done such a video?

Ahhhh, WD-40 is /not/ a lubricant! ;) Very cool project. Thank you for the video!

And there was me thinking that I was your biggest fan. 😬

Would love to see such crazy builds more Angus. Well done.

Fan tastic Angus.. Will be building one . thanks for the files. Look forward to the revised version

10:32 You don't need a Current Meter. Just use a 1Ohm or 0,1Ohm Resistor and meassure the Volate across it. Then you can calculate the Amps with Ohms Law.

I have done some acoustic analysis on the fan revving at full power (12:49). The main frequency is 1898 Hz. With a 9 bladed fan that means 1898 / 9 = 211 rotations per second, or 12653 RPM. Much more than the 3330-ish RPM you stated at the start of the video (5:50). The difference is about a factor 4. Which coincidentally is the gear ratio. Any idea what may cause this difference?

I just bought my first 3D printer last week to prototype some parts. While looking for info on the subject, I came across your RU-vid channel. I love your content! And this fan is beautiful (and a little bit scary)! 😂😍

Happily surprised that Microcenter sponsored this! I'm lucky, there's one about an hour away from me. I'm not a "new" customer though so maybe I'll have to sign my wife up to get that sweet Ender deal. :) Also love the shout-out to Major Hardware, he's definitely up and coming. Cool build! Would def like to see it at its full potential.

I guess I'm no longer your biggest fan 😂

Should be tested by GamersNexus :D

I'm gonna be smiling for a week after this one. Absolutely epic project, many thanks.

Dude this is so awesome! I wonder how much the blades deform at full speed, it seems like your design held up really well.

The only clickbait that is actually not a clickbait. Always cool stuff, man. Good job.

Awesome! Looks perfect for clearing out dust after pulling a plaster ceiling down!

Yeah, it is nice to have a Microcenter nearby. I sure would miss having them around if I had ever moved out of state :)

I visit Microcenter more than my office sometimes. Love them so much

8:22 oh my god I cracked up your quote at this spot "well...that's...terrifying.... Time to finish it!~"

That was VERY impressive. You are so incredibly skilled man!

Loved every minute of this. Fantastic mate!

You NEED to send this to Steve and the GN team for testing. Awesome work as always!

the last five minutes of this video have amazing early RU-vid energy and I love this

Well Done Mate. Astonishing creation. There's a lot more potential here with this creation that you even have shown. Build it with a direct drive AC induction motor of about 3600 RPM, the speed can be varied with a variac or dimmer. Also THIS design would be ideal for a SERIOUS ventilation fan in a large shop or barn out in the farms. They are getting very expensive now. Also for temporary use in paint booths for evacuation of air and fumes. AND Power it also with standard regular induction motors that do 1100 or 1800 RPM from HVAC systems on small fans and squirrel cage blowers would fit right into that opening and size with little modification. Those motors are highly efficient and low current drawing only about 100 watts or even less which would enable you to run this boss thing all day. That kind of build would provide a moderate speed with a continuous duty motor that could go in a window and ventilate 30X better than the cheap 3 speed box fans sold in large stores. Another mod of this design would be to use a 12V motor and use a smaller version for radiator cooling on custom cars. There are lots of electric radiator fans now but they are expensive and very poor in efficiency compared to this streamlined blade design. Of course in those serious applications the lights and so on would not be incorporated.

Yeah nice work man, a creation to be proud of. I can't help but wonder how much smoother it would have been with some balancing. Did you know you can buy bearings without the grease and seals and they're cheaper? :)

Great fun video to watch. Maybe use a lower kva motor for direct drive. All you need now is a hand-held version to make leaf blowing more practable. 🍁🌪️

Great job Angus. That was super fun. When can we expect to see this on a Toolhead 🤣?

Great project Angus! Love it.

Best video in ages! Im in the gong too the rain was crazy hope you didn't get flooded.

I run the ''cooldown'' lounge for a convention and boy, making a wall covered with a few of these is so tempting

Dang that is so COOL!!!!!!! I love the case! I so want to make something with that futuristic chamfer style.

Angus, I've been watching your account on and off for years now and every video I watch never ever disappoints, love your shows!

Just brilliant. Very fun video to watch, thanks.

A current meter wouldn't really measure power output. Even though there is a reduction from the motor output, there is probably a lot of load and resistance on the motor from the giant fan so there will be a lot of current draw regardless of power so that doesn't necessarily correlate to performance. Loved the project though, it looks amazing and pretty powerful!

Epic project 2022 candidate right here dude!!!

For the love of Pete! This is amazing. Major Hardware should be saluting you... And then printing one of these for himself. ;) I may have to print one of these, to use as a clock. (just to have an excuse to always have it turned on)

Really cool video! Greetings from the UK.

I'm glad you had fun because this is one of your funniest videos ever

Awesome my good man !!!! This is why I love additive manufacturing !!! I make what I want when I want!!! 🥰

I love it! Only little thing you could mains improve is the seams in the white rgb shroud

This video was so entertaining! I hope you make a PC case on which attach your fan.

This seems like a fun project to build the rest of the PC case to scale!

Angus, You posted a vid several years ago where you were talking about art pencils and how tools don't make you a better artist, practice does. Do you remember which video that was? I took what you said to heart and it's made all the difference. I want to share that video with someone else. Thanks for all you do!

For the fidget spinner treatment, yeah you can strip the grease oil, but you can also replace it with a low viscosity oil. Since there's relatively low load on the bearing itself, low viscosity oil would keep the longevity as well as the free spinning characteristics

You win on the most powerful PC fan build! I hope those build files come with a major disclaimer about the end product being dangerous. Geez! I'd want to be behind a blastproof screen before I'd fire that thing up! 🤣 Great fun idea Angus 👍

Such a fan! I kinda was hoping to see the inside of the gearbox. Given it's portable, make yourself a small go cart that's fan powered.

THIS! IS! HILLARIOUS! ...and awesome. 😆 Thack you for your creativity! ❤

This is fun. I wish the blades were in the PETG as well, but nice done man.

That is a amazing project. I could see me making one of these for the computer room but a cheap box fan motor would make it pretty quiet🤔

As soon as I saw this I thought of The Fan showdown series! Been with it since season 1!
