I will have them for sale by next month. Already have 20+ pre orders. Let me know if your interested. Non branded, 3d printed, upgraded motor. Led upgrade available.
That motor uses a worm gear drive, which does not allow for "back driving." This is due to the physical geometry of the gear engagement. My best guess is that the relatively large rotational inertia of the fan blade is able to overcome this by displacing the motor shaft and/or shearing metal from the worm and/or wheel gear. This will never work well as every time the fan is powered down, it is going to cause excessive wear. Unfortunately, a different gearbox is the only fix for this problem.
@@kasuraga someone who wasn't aware of the issue obviously. For a one of a kind prototype, i can see why they couldn't be bothered fixing the flaw once it was discovered. It could be halfassed fixed by putting in circuitry to slowly ramp power down before shutting off, but you'd have the same problem anytime someone unplugged it under load.
This is awesome to learn. Thanks for the educational and well-written post. We don't know much about the motors/drives they used for this, so we just did a like-for-like swap. Great to learn here why it was failing!
@@Wooble57 but seriously though, it could have easily been prevented by not using a stupid worm drive gearbox to spin something with that much inertia. You could probably destroy the gear box with a single finger on that fan blade.
Corsair, if you're watching, letting Steve hang on to the fan and play around with it some more is better marketing for you than anything the fan would have been used for originally.
I worked in an industrial facility that had a... massive... blowiematron that ran a fertilizer drying system. 20,000 RPM, about 3 feet diameter fan. These types of things certainly exist!
The reason for the grinding and all the metal shavings inside the gearbox is the worm gear. It transfers the rotational force in a different direction so it can have way higher torque (which in this case, it needs that torque for that tiny motor to move that massive fan). The downside is that the gear can only move if the motor is moving, making it a very poor choice to use this particular design of gearbox. When the power to the motor us cut off, the worm gear will stop turning and the momentum of the fan will keep spinning, causing the regular gears to grind against the worm gear. That's why its having the grinding issue. Sorry for the rant. Just had to say it since no one in the video did :P
Another great solution would be to do away with the motor and gearbox altogether and go with a direct drive brushless pancake motor on PWM control. Or if you wanted to get really crazy, an MIT Cheetah style CAN-BUS pancake motor...but really due to it's complexity and relatively low RPM it's probably not a great choice.
ive got 6 corsair SP fans in my case and at least 2 of them have (i assume) ball bearing noises, and one needs to be set to 70%+ or it stops spinning. theyre about 3 years old. meanwhile the ~12yr old noctua 140mm fan is running as flawlessly as the day i got it.
For giggles what you needed was a slow motion montage of this fan blowing through Steve and Patrick's hair like they're supermodels while some funky sounding music is playing.
In the 1980s, Maxell became an icon of pop culture when it produced advertisements popularly known as "Blown Away Guy" for its line of audio cassettes. The original campaign began as a trade ad in 1980 and was made into TV spots in 1979 which ran throughout the 1980s. Steve Steigman was the photographer and Richard Wagner's "Ride of the Valkyries" was used for music. In the UK the music used was "Night on Bald Mountain" by Modest Mussorgsky. The ads depict a man sitting low in a (Le Corbusier) high armed chair (on the right side of the screen) in front of, and facing, a JBL L100 speaker (the left side of the screen). His hair and necktie, along with the lampshade to the man's right and the martini glass on the low table to the man's left, are being blown back by the tremendous sound from speakers in front of him - supposedly due to the audio accuracy of Maxell's product. He is shown desperately clinging to the armrests but defiantly looking ahead at the source of the music through sunglasses, though calmly catching his drink before it slides off the end table. Television commercials showed the chair, a drink and nearby lamp, being pushed away from the stereo by the strong force of the sound waves. The image became the de facto standard of those who believed their stereo equipment had sufficient power or accuracy to move the mind and the soul. The model for the UK (not US) ad campaign is thought to hace been musician, Peter Murphy, of the group Bauhaus. The model for the US campaign, however, was the makeup artist hired for the shoot by photographer Steve Steigman. The impact of the advertising campaign on popular culture still resonates today: "Blown Away Guy" was recently parodied on the popular animated television show Family Guy in the episode "Model Misbehavior". This is only the most recent in countless parodies over the years, which includes a parody in the John Ritter film Stay Tuned, (which featured a character's head being blown off by a "Max-Hell" tape). In the 2010 movie Jackass 3D, the commercial is parodied with Ryan Dunn sitting in the chair, while the blast from a jet engine sends the set blowing away.
A simple fix would be to install a dog clutch on the hub assembly. When driven by the motor it would spin the fan, but when power is cut or reduced to the motor the clutch would slip until the blade assembly slowed down enough to be driven by the motor. The nature of a worm gear setup is that the worm gear cannot be driven by the components connected. More grease won't help any.
I might try this design. Currently we are working on a gear reduction plan but these are metal parts that need lubrication constantly. I like the dog clutch approach. I could 3d print everything and purchase a shoe and ring from a manufacturer. Good idea!!
Literally! I’d buy this if it was an official thing to buy. It looks so cool attached to the side like that. Maybe a little more faster but still, pretty cool!
I wish you had the opportunity to perfect the current design: * Put in at least 10w motor, * Greased up or rebuilt the gearbox, * Replaced belts with a single belt. And then in another episode make it extremer with even more powerful motor and powersupply.
I think it's more of the gearbox locking up, there is a lot of torque for that tiny gearbox to take. replace it with one that free spins on shutdown and it should work better.
Remove gearbox locking for avoiding belts and gears eating up on fan speeding down (maybe best solution is to use ratchet mechanism, so the fan wouldn't give its torque to motor when stopping). Not sure if putting more powerful motor help because of a fragile gearbox design (prolly it would just eat up gears faster on start). Using stretchable onebelt would fix the start torque, as it will damper it when hitting 0 to 100 rpm of fanblades (and yes, those multiple belts are worst without individual seats on gear).
You can really see that this thing screams "quick prototype" lol. The motor, the gearbox, the belts, even the board. Probably just put in what they had lying around. Pretty much all of those parts would need to be replaced if one was trying to make something functional. First, the motor needs to be at least double the power. Second, the gearbox needs to be a higher ratio and not lock up to transfer that power into RPM. The belt finally needs to be a single wide proper one. Then it would go real hard, probably be quite scary too. Although to be truly frightening the board would need to be replaced to take outlet current and the motor and gearbox taken out from an industrial fan. ...or you know, at that point might as well should have just printed a mod for a standard industrial fan and added RGB
I honestly would have just said scrap the whole gearbox/belt system and see if there wasn't some low-profile brushless motor that could fit in there and attach the fan hub directly to the motor (direct-drive configuration like most fans). Or if not that then just use a smaller brushless motor, get a smaller belt pulley for the motor shaft, and a larger pulley for the fan blades for a belt-drive setup (again just leave out the gearbox). Better yet but more expensive and difficult would just be to build a custom hub motor that's basically the same scaled-up design of what normal brushless fans use.
I need to have this as my ceiling fan for my room! Btw, Corsair should actually do a limited run (1000-2000) of these fans as a novelty/collectors item.
@@TheObsesedAnimeFreaks And improve on the motor. If the fan dies after just 15 minutes of use then it's nothing more than a large novelty paper weight, but if they could find a way for it to be reliable as a fan (or at least a kinetic sculpture) then they'd improve its value considerably.
i've always wanted to replace the side panel with a huge silent fan, corsair should keep working on this and launch it with some grill, dust filter and mounting options for their cases
Time to DIY! Trends only take off if people start building and buying. I'm building a custom water loop that uses a motorcycle radiator and four 120mm fans, but your desire will probably need car parts and some window screen for the filter. If you can get your hands on it, a plasma cutter would make quick work of a case side panel, though cleanup will be tedious.
@@zabique There is not a single 3D printer large enough to print those huge size pieces. You see the fan is made out of one plastic... If you think is possible go watch Linus 3D PC case video he made hundreds of smaller pieces even with one of the largest 3D printers you can buy.
@@strohhuttv8848 Your comment is highly exaggerated/ignorant (i dont meant in an insulting way). There are actually 3D printers in existence or even purchasable on order of any size that can print even pieces of any size. 3D printing is scalable meaning dimensions of such a printer and the parts can be made in any size the only restriction to 3D printing is the material used to print with and complexity of the part to be printed. Many experiments are made to print with cement-like paste for printing construction materials ( yes even large parts or even WHOLE HOUSESES ) youtube "3d printing a house" down to 3d printing electronics at nano scale with conductive materials youtube "Nano Dimension: The Capabilities of Electronic 3D Printing" 3D printers arent only the small boxes you think of. They exist in many variatious of ANY size for many different purposes. Yes even this fan from Corsair. 3D doesn't mean "print the whole thing in one go" NO! you ALWAYS produce parts in segments in ANY situation! that should be obvious and doesnt mean it's "fake". 3D printed products simply mean Their parts are produced FROM a 3D printed. it doesnt mean "we push a button on a 3D printer and the whole thing came out that way" thats just dumb
@@PutsOnSneakers Even if this is the case not a single normal consumer can buy one of those. Those huge big 3D printers are not even durable for us consumers. And companies made huge parts of plastic and other materials even BEFOR we got 3D printers. The development of 3D printers made it easier for the average person to 3D print they own pieces with some limitations.
just buy a few server's, stack as many as you need to reach 5DM height, and bolt this to the back. that would also (at somewhat human prices) allow you to create enough heat for this, with maybe 20cpu's, and a few server GPU's. dam, now i wana build this.
Easy: the fan is the side panel. 👌don't even need to build a case around it, just some adapters for securing it. It would look doooope! Edit: should've watched the video first...
Can tell you exactly how that gearbox "locks up" if the motor isn't turning: there's a worm gear in the chain. Worm gears can only drive the gear they engage; they can never be driven by the gear they engage. :3
Maybe I'm not understanding your question, but I assume the change in speed of the motor is quicker than the change in speed of the huge plastic blades causing the blade to then try and drive the gears causing wear on the worm gear. And turning it off completely was probably even worse as those big blades will take time to slow dow n. Ideally the blade would have been affixed with a slip collar to allow them to continue to rotate with the gears completely stopped. I figure this silly thing was made for trade show booth or something, so engineering for functionality was the least of their concern and hardly for long term use.
@@davidd3065 Not exactly. Think of a worm gear as like a rack but spun around the axle to make a spiral gear tooth. Worms are fixed in place on the axle so they can't slide back and forth like a rack would. Thus, the gear enmeshed with the worm can't drive the worm. It can only be driven by the worm. :)
This is Corsair's answer to GN always harping on airflow, airflow, airflow. Oh you wnt airflow? We can give you that! This is a great PR move for Corsair and I'm so pleased they sent you this awesome novelty fan.
Have a lot of good Corsair gear in my Desktop, seeing this giant fan is both hilarious and makes me want one, maybe stick it to the window of my room since it can get to 23c in here when gaming sometimes and my Canadian heat tolerance hates temps of 18c XD
I admire Steve's ability to be disgusted by a product and yet turn a review of said turd into an entertainingly snarky presentation. Past a certain point, I wouldn't find it funny anymore. I'd just get depressed that this was the future of homebuilt PCs and even more depressed that the psychos actually had the stones to send him a review copy. I also genuinely don't think it'll ever get better.
Since the motor locks up when you shut it off, you really need to slowly reduce the speed before shutting it off. I would bet that the momentum of the fan spinning is what keeps stripping the gears.
Yeah and a toothed belt doesn't help. You need a smooth drive belt with that worm gear, because of the inertia. Problem is the motor isn't powerful enough which is why they used a worm gearbox. I would've thought a bigger motor direct drive, obviously with a ratio, would be better
The way companies are heading for higher and higher TDPs right from CPUs to GPUs and in the future the trend is expected to continue, seems like Corsair is well prepared for the future.
Should have saved this till april. Would have been wonderful to do the entire video straight faced without mentioning the size in the format of your future fan reviews.
If Microsoft can make an Xbox minifridge, and AMD can make a mountain bike, then Corsair can make a floor fan that looks like an RGB case fan. Please Corsair! I need this!
You could probably 3D print your own and build it using drone components or the electronics from an actual box fan. The biggest difficulty will be printing it in sections and gluing them together.
Heh, hopefully not too much bigger, my Sapphire 5700XT Nitro+ is already a big enough triple fan monster that barely fit in my Thermaltake Core V21 case XD
Daaayum, I really need Corsair to make me one of these 500mm rgb fans (with a much beefier motor) to put in my bedroom window to cool my room off! Plus the rgb lighting would have an added bonus of mood lighting & looks way cooler than a regular box fan!
Ngl, if Corsair sold it as a box fan I'd buy one. So many crappy box fans, Corsair would at least be offering something of better build quality. (And with rgb to boot)
This fan is amazing, even as a one off gimmick, it looks so cool, I'd get one as a show piece,, and the fact that it spins (with clearly the wrong motor) makes it even more awesome.
They could make a side panel with a flat-ish version, like 350-400mm. Can't see why not, whether it's more efficient to have one big fan and maybe 2 small ones vs having like 8 small fans
In 1998 i built my first computer. Intel celeron pentium 2 or some such thing. Our house did not have A/C, my father didnt believe in it, in california, in the summer, with at least 3-4 weeks of above 100°F temperatures. So, very quickly, my brother and I, who had built matching computers, couldnt deal with the high ambient temperatures. So we bought walmart box fans, removed the side panels, and strapped them to the computers. Worked amazingly well, we later added another store bought fan to the front. Love you gn! This was awesome. Good memories.
Plenty of car rad's, but fin density and the fact that zero will be copper or brass is a bit of an issue. Sure you CAN run mixed metal loops, heck ive done it myself in the past, still not a great idea even if it is not as bad as many make out, most aio's use alluminium rads anyway but they tend to get thrown away more regularly than parts of open loop systems so nobody sees how bad they become, plus you cant see inside them without pulling them apart anyway.
I watched this episode with my brothers, my Uncle and my Dad!! I'm going to be the 1st female engineer in our family when I graduate and this was very exciting to watch with my fams!! I've now subscribed to your channel because I noticed this incredible video was made 3mos ago, yet it only showed up in my queue 2 days ago! I'm going to dig around in your archives and see what other treasures I can find.. between you and Linus, I'm like NEVER bored and genuinely have a great time and learn many things they'd NEVER teach us in the classrooms!! LOL *hugs* to GN! 💖❤️💕
14:24 "This is in some ways equivalent to putting a floor fan from a home improvement store right up against the case... except this one has RGB." Heck, I'm sold.
this should be a line of "gamer desk fans" I would genuinely love this for a cool gaming setup addon (especially in Aus where its hotter than the sun most of the time)
I would totally buy something like this. I would either get one for a ceiling fan, or use it as a floor box fan. Best part, the rgb can sync with my PC.
Maybe reverse the pitch of the fan blades though, so we can look at the "cool" side while being cooled. Deffinitly would want one as a window fan, ceiling fan, or maybe attached to one of those movable mic armatures you can clamp to your desk/monitor mount
The drive gear should be a on a set of pawls so that it spins the fan, but when the motor stops turning the fan can continue to spin/slow down naturally. That way you aren't tearing up the drive belts and transmission.
Such an incredible content. I'm blown away. Thank you Steve. Thank you for Corsair providing the fan I hope they follow what the GN team is doing with it and let them hang to it until the fan testing machine arrives.
I'd like to say that everyone owns part of the i.p. for this. All of us without AC at some point in our lives have tried using a big box floor fan on our opened PC case to help keep it cool during the summer lolol
If made with injection-molded plastic, it depends a lot on how many they think they'll sell. The tooling would be very expensive - the plastic is not. Resin casting on the other hand is labour-intensive, so per-part minimum costs rise. 3D printing is doable but not fast, and very large 3D printers or having workers joining together many small parts are also an added expense. There's a good reason niche products simply cost more.
Make a new motor design with Linus group, then run at 1000rpm, a new radiator that can adapt a case for the fan, this will be truly epic for both channels.
@@AhmadAbuGdairi Maybe? I suspect the hub of a car motor would be too big for it to be the right scale though. But if the car radiator fan internals are the right size, might be a good match. Main concern is those are actually really powerful motors and I'm not sure the 3D printed fan blades would take it, you'd have to run it at a lower voltage, assuming the motor would actually work down there.
This is hilarious. All throughout the video I couldn't stop my brain asking: "how are those guys inside a cartoon with a giant PC case fan?" :D Also the the value of the "biggest PC fan" pun.
Would be amazing as just a floor fan in my gaming room. Epic. My daughter and dogs would just have to learn the hard way to not stick their fingers and nose in it
The reason there is that issue when you shut down the fan, is you can't back-drive a worm gear. The reason they used one, was its the cheapest way to do a large speed stepdown, which was necessary to drive such a huge fan with such a tiny motor.
Worm gears aren't great for constant load with no oil either.. so it was a cheap solution. You can fix the back-drive issue if you add a ratchet clutch. But I'd probably just go for some other step down solution, planetary gears or precision gears.
Corsair, pls let them keep the fan! Steve is a Saint and everything he touches turns intro a performance oriented marble and that fan will surely be happy to receive a can size brushless motor and spin to over 10k rpm.
@@michaelmechex now imagine the fan's spec sheet stating you need a 520w or higher PSU. That's not for the total system, that's for the isolated fan only lmao
This fan needs a RC brushless motor and a direct drive with oneway diff in the fan shaft, with that you can set a PWM signal to the ESC and control the speed with the motherboard, direct 12v from a extra gigabyte PSU is a must.
Yeah, I can't help but wonder why they didn't use a brushless motor to start with, that geared motor seemed like a bad pick, especially since it locked up when stopped
Hope it, seems like big fans really are a good design choice for those who wish for silent operation without loosing to much in potential airflow. Used to use a HAL case with a large side fan, was great for that, but it got outdated in other means and the industrial design didn't really suit my new PCs location in the livingroom.
Interesting design. Gearmotor definitely not designed for continuous use for sure. This could be designed with a proper brushless motor for long term use. And higher speed. Imagine that running at 2000 rpm! :-D
Larger fans tend to run slower, because the larger diameter means the edge of the fanblade moves through air faster at the same RPM. At some point it becomes an issue of blade strength. Though if you run half RPM at 10x the size, you are still moving a lot more air.
Continuous use yes. Slowing down to anything else but a constant speed, no. Even turning it off would strip the wormgear first time. You'd need a clutch between the wormgear and the gearbox to allow it to slip and not back drive the motor from the fan. As soon as I saw the motor when he opened it, I knew what the problem was.
My favourite part of this is the perfectly reproduced pebble texture on the fan body, sized up in proportion to match the larger fan size. The close-up shots almost look like macro photos, props to whoever produced the parts!
If it were any other media outlet I highly doubt they would’ve been able to repair the fan by taking it apart, actually finding and replacing the replacement part and successfully repairing it. Very impressed with Patrick here and I think Corsair’s probably quite happy (and relieved) that they sent it to such a resourceful team.
I guess this fan was designed for cooling down the gamers when they are playing games and when all of the exhaust heat is being blown towards the gamers causing them to overheat and throttle.
Worm gears are great for large gear reductions, like when you want to use an absolutely undersized motor on a large slow device. One design feature is that because they have a very shallow thread pitch which makes it possible to create decent output torque with a very small input torque. Like pulling a sled up a very shallow incline. Another feature is that they tend to be self locking (good for a trailer Jack, but not for this), so if you try to power the system in reverse, it will not overcome the frictional forces in a smooth fashion. Like if you stopped pulling the sled, it would not slide back down the hill on its own gradually. It sounds like there was enough momentum to force the pinion or worm to rotate, but alternating between dynamic (smooth) and static (sticky) friction.
that belt drive setup is probably in there for the reason of that motor/gearbox locking up, the belts slip, letting the fan disk spin until it stops with some pretty stiff braking once the motor stops.. that fan disk is essentially a big flywheel when it comes to it spinning/being spun
Honestly after seeing this the thought had occurred to me to upscale the models for a fan off McMaster Carr and then print out panels to fit around a box fan. Not to use as a PC fan, just to make it look like one.
Honestly now I'm interested to see this done more. Also fixing the issues this one has. Those being make it a single stronger pulley, and replace the motor/gearbox with something actually more suited for this project instead of locking up when shut down. I would love to see an actual commitment into making a pc literally incorporate such a massive fan.
I think a wind tunnel style case with this being the sole fan in the whole thing would be AMAZING! Basically you just have a shroud with this in the front, that concentrates it down to the case front, and it rams air through the case out the back.
Those Delta Blowie Matrons consume 4x the power of this super-sized Corsair fan. You should totally hook one up to your fan testing machine once it comes in.
As someone has already pointed here, find a single belt. For what I can tell, the motor itself does not need to be more powerful but the gearbox is going to give problems since it cannot freely move with the fan. As the fan accelerates and decelerates, the gears get al crunched down by its own teeth. There is surely a BLDC motor that can fit inside that thing and could even be programmable for PWM signal from the motherboard.

That motor uses a worm gear drive, which does not allow for "back driving." This is due to the physical geometry of the gear engagement. My best guess is that the relatively large rotational inertia of the fan blade is able to overcome this by displacing the motor shaft and/or shearing metal from the worm and/or wheel gear. This will never work well as every time the fan is powered down, it is going to cause excessive wear. Unfortunately, a different gearbox is the only fix for this problem.
That's exactly what I thought. It's such a shit design. Like, who the fuck came up with that? there are SO many better ways of making it work.

Steve: "We hope Corsair forgets about about it and lets us keep it"
Also Steve: Posts video about it on the channel (that Corsair no doubt monitors).
But, in doing so, kinda asks to keep it for a bit longer anyway
The reason for the grinding and all the metal shavings inside the gearbox is the worm gear. It transfers the rotational force in a different direction so it can have way higher torque (which in this case, it needs that torque for that tiny motor to move that massive fan). The downside is that the gear can only move if the motor is moving, making it a very poor choice to use this particular design of gearbox. When the power to the motor us cut off, the worm gear will stop turning and the momentum of the fan will keep spinning, causing the regular gears to grind against the worm gear. That's why its having the grinding issue. Sorry for the rant. Just had to say it since no one in the video did :P
Would be easily solved with a one-way clutch/bearing.
Yep, that is the suck part of the worm gear
Needs a chevy 350.
Another great solution would be to do away with the motor and gearbox altogether and go with a direct drive brushless pancake motor on PWM control.
Or if you wanted to get really crazy, an MIT Cheetah style CAN-BUS pancake motor...but really due to it's complexity and relatively low RPM it's probably not a great choice.

ive got 6 corsair SP fans in my case and at least 2 of them have (i assume) ball bearing noises, and one needs to be set to 70%+ or it stops spinning. theyre about 3 years old. meanwhile the ~12yr old noctua 140mm fan is running as flawlessly as the day i got it.

It's a wig. He took it off in one of his videos recently
In the 1980s, Maxell became an icon of pop culture when it produced advertisements popularly known as "Blown Away Guy" for its line of audio cassettes. The original campaign began as a trade ad in 1980 and was made into TV spots in 1979 which ran throughout the 1980s. Steve Steigman was the photographer and Richard Wagner's "Ride of the Valkyries" was used for music. In the UK the music used was "Night on Bald Mountain" by Modest Mussorgsky.
The ads depict a man sitting low in a (Le Corbusier) high armed chair (on the right side of the screen) in front of, and facing, a JBL L100 speaker (the left side of the screen). His hair and necktie, along with the lampshade to the man's right and the martini glass on the low table to the man's left, are being blown back by the tremendous sound from speakers in front of him - supposedly due to the audio accuracy of Maxell's product. He is shown desperately clinging to the armrests but defiantly looking ahead at the source of the music through sunglasses, though calmly catching his drink before it slides off the end table. Television commercials showed the chair, a drink and nearby lamp, being pushed away from the stereo by the strong force of the sound waves. The image became the de facto standard of those who believed their stereo equipment had sufficient power or accuracy to move the mind and the soul.
The model for the UK (not US) ad campaign is thought to hace been musician, Peter Murphy, of the group Bauhaus. The model for the US campaign, however, was the makeup artist hired for the shoot by photographer Steve Steigman. The impact of the advertising campaign on popular culture still resonates today: "Blown Away Guy" was recently parodied on the popular animated television show Family Guy in the episode "Model Misbehavior". This is only the most recent in countless parodies over the years, which includes a parody in the John Ritter film Stay Tuned, (which featured a character's head being blown off by a "Max-Hell" tape). In the 2010 movie Jackass 3D, the commercial is parodied with Ryan Dunn sitting in the chair, while the blast from a jet engine sends the set blowing away.
@@zzzcocopepe WAIT WHAT
@@zzzcocopepe my whole life was a lie
A simple fix would be to install a dog clutch on the hub assembly. When driven by the motor it would spin the fan, but when power is cut or reduced to the motor the clutch would slip until the blade assembly slowed down enough to be driven by the motor. The nature of a worm gear setup is that the worm gear cannot be driven by the components connected. More grease won't help any.
Yup, 100% agree, they need a dog clutch/overrunning clutch to divert the momentum/inertia of the fan blade assembly.
I might try this design. Currently we are working on a gear reduction plan but these are metal parts that need lubrication constantly. I like the dog clutch approach. I could 3d print everything and purchase a shoe and ring from a manufacturer. Good idea!!

@@ikannunaplays noctua NEEDS to make a tan and brown case with a full sized side panel fan
This is gonna be even bigger than glass side panels
Aerocool use to have an entire line of cases like this, in particular the S9 was amazing, but they are terrible at marketing their products
Literally! I’d buy this if it was an official thing to buy. It looks so cool attached to the side like that. Maybe a little more faster but still, pretty cool!
I wish you had the opportunity to perfect the current design:
* Put in at least 10w motor,
* Greased up or rebuilt the gearbox,
* Replaced belts with a single belt.
And then in another episode make it extremer with even more powerful motor and powersupply.
I think it's more of the gearbox locking up, there is a lot of torque for that tiny gearbox to take. replace it with one that free spins on shutdown and it should work better.
@@nigh01 I mean, I would just direct drive it with a larger motor and maybe throw a board in to slowly ramp power at startup.
Remove gearbox locking for avoiding belts and gears eating up on fan speeding down (maybe best solution is to use ratchet mechanism, so the fan wouldn't give its torque to motor when stopping). Not sure if putting more powerful motor help because of a fragile gearbox design (prolly it would just eat up gears faster on start). Using stretchable onebelt would fix the start torque, as it will damper it when hitting 0 to 100 rpm of fanblades (and yes, those multiple belts are worst without individual seats on gear).
You can really see that this thing screams "quick prototype" lol. The motor, the gearbox, the belts, even the board. Probably just put in what they had lying around.
Pretty much all of those parts would need to be replaced if one was trying to make something functional.
First, the motor needs to be at least double the power. Second, the gearbox needs to be a higher ratio and not lock up to transfer that power into RPM. The belt finally needs to be a single wide proper one.
Then it would go real hard, probably be quite scary too. Although to be truly frightening the board would need to be replaced to take outlet current and the motor and gearbox taken out from an industrial fan.
...or you know, at that point might as well should have just printed a mod for a standard industrial fan and added RGB
I honestly would have just said scrap the whole gearbox/belt system and see if there wasn't some low-profile brushless motor that could fit in there and attach the fan hub directly to the motor (direct-drive configuration like most fans). Or if not that then just use a smaller brushless motor, get a smaller belt pulley for the motor shaft, and a larger pulley for the fan blades for a belt-drive setup (again just leave out the gearbox). Better yet but more expensive and difficult would just be to build a custom hub motor that's basically the same scaled-up design of what normal brushless fans use.
GN does no clickbait, the frikn thing is real! Thats why we love em.
I honestly did a double-take when I saw the thumbnail, I didn't realise at first glance that the fan was to scale 🤯
I legit got annoyed at the thumbnail cus I hate clickbait, but clicked anyway because it's gn... The shit is real lol

GN is fine. It's fine.
And I thought the 200mm fan on my Thermaltake Core V21 was huge, dear lord of Fans I was wrong, and that thing is magnificent

Btw, Corsair should actually do a limited run (1000-2000) of these fans as a novelty/collectors item.
they would have to work with an actual box fan manufacturer for that though
@@TheObsesedAnimeFreaks And improve on the motor. If the fan dies after just 15 minutes of use then it's nothing more than a large novelty paper weight, but if they could find a way for it to be reliable as a fan (or at least a kinetic sculpture) then they'd improve its value considerably.
@@B3RyL I mean all they need is a better motor, wouldn't be exactly difficult to do.

Such a massive fan that I swept in and swiftly acquired the first comment. Breezed past everyone here, easily. 😂
I'm curious if Corsair is gonna make it this 500mm their onlyfan in this category.
i've always wanted to replace the side panel with a huge silent fan, corsair should keep working on this and launch it with some grill, dust filter and mounting options for their cases
Time to DIY! Trends only take off if people start building and buying. I'm building a custom water loop that uses a motorcycle radiator and four 120mm fans, but your desire will probably need car parts and some window screen for the filter. If you can get your hands on it, a plasma cutter would make quick work of a case side panel, though cleanup will be tedious.
The price would be crazy expensive but I'd buy it anyway lmao
Only issue would be dust
There's a post on tech support mcguyver where they zip tied a grid of fans and replace their side panel with that
this would be a badass product image the exhaust being the entire size of the side of your case
I can't get over the fact that they actually made it. Absolute madness.
it's 3d printed fake.
@@zabique There is not a single 3D printer large enough to print those huge size pieces. You see the fan is made out of one plastic... If you think is possible go watch Linus 3D PC case video he made hundreds of smaller pieces even with one of the largest 3D printers you can buy.
Companies making things like this amidst the "shortage" is another indicator the "shortage" is purposeful by bad actors not some organic situation.
@@strohhuttv8848 Your comment is highly exaggerated/ignorant (i dont meant in an insulting way).
There are actually 3D printers in existence or even purchasable on order of any size that can print even pieces of any size.
3D printing is scalable meaning dimensions of such a printer and the parts can be made in any size the only restriction to 3D printing is the material used to print with and complexity of the part to be printed.
Many experiments are made to print with cement-like paste for printing construction materials ( yes even large parts or even WHOLE HOUSESES ) youtube "3d printing a house" down to 3d printing electronics at nano scale with conductive materials youtube "Nano Dimension: The Capabilities of Electronic 3D Printing"
3D printers arent only the small boxes you think of. They exist in many variatious of ANY size for many different purposes. Yes even this fan from Corsair.
3D doesn't mean "print the whole thing in one go" NO! you ALWAYS produce parts in segments in ANY situation! that should be obvious and doesnt mean it's "fake".
3D printed products simply mean Their parts are produced FROM a 3D printed. it doesnt mean "we push a button on a 3D printer and the whole thing came out that way" thats just dumb
@@PutsOnSneakers Even if this is the case not a single normal consumer can buy one of those. Those huge big 3D printers are not even durable for us consumers. And companies made huge parts of plastic and other materials even BEFOR we got 3D printers. The development of 3D printers made it easier for the average person to 3D print they own pieces with some limitations.
Okay Corsair, here's the deal: you build a case around that fan, and I will buy it. I'm not even slightly kidding (part of me wishes I were).
My question is: is there actually any case that can support such fans?
Cpu air cooler for it or an aio with 2!
...saves you office space. That thing can easily hover under the ceiling 😆
just buy a few server's, stack as many as you need to reach 5DM height, and bolt this to the back.
that would also (at somewhat human prices) allow you to create enough heat for this, with maybe 20cpu's, and a few server GPU's.

Edit: should've watched the video first...
In total awe at the size of that lad, what an absolute UNIT
Can tell you exactly how that gearbox "locks up" if the motor isn't turning: there's a worm gear in the chain. Worm gears can only drive the gear they engage; they can never be driven by the gear they engage. :3
Came here to say this. You beat me to it.
Maybe I'm not understanding your question, but I assume the change in speed of the motor is quicker than the change in speed of the huge plastic blades causing the blade to then try and drive the gears causing wear on the worm gear. And turning it off completely was probably even worse as those big blades will take time to slow dow n. Ideally the blade would have been affixed with a slip collar to allow them to continue to rotate with the gears completely stopped. I figure this silly thing was made for trade show booth or something, so engineering for functionality was the least of their concern and hardly for long term use.
@@davidd3065 Not exactly. Think of a worm gear as like a rack but spun around the axle to make a spiral gear tooth. Worms are fixed in place on the axle so they can't slide back and forth like a rack would. Thus, the gear enmeshed with the worm can't drive the worm. It can only be driven by the worm. :)
This is Corsair's answer to GN always harping on airflow, airflow, airflow. Oh you wnt airflow? We can give you that! This is a great PR move for Corsair and I'm so pleased they sent you this awesome novelty fan.

I admire Steve's ability to be disgusted by a product and yet turn a review of said turd into an entertainingly snarky presentation.
Past a certain point, I wouldn't find it funny anymore. I'd just get depressed that this was the future of homebuilt PCs and even more depressed that the psychos actually had the stones to send him a review copy. I also genuinely don't think it'll ever get better.
Since the motor locks up when you shut it off, you really need to slowly reduce the speed before shutting it off. I would bet that the momentum of the fan spinning is what keeps stripping the gears.
Or just use the right gears
Yeah and a toothed belt doesn't help. You need a smooth drive belt with that worm gear, because of the inertia. Problem is the motor isn't powerful enough which is why they used a worm gearbox. I would've thought a bigger motor direct drive, obviously with a ratio, would be better
Belt drive should slip before the gearbox selfdestructs. Not saying you're wrong, just providing a counter-argument from an engineering POV.
The way companies are heading for higher and higher TDPs right from CPUs to GPUs and in the future the trend is expected to continue, seems like Corsair is well prepared for the future.

In 1998 i built my first computer. Intel celeron pentium 2 or some such thing. Our house did not have A/C, my father didnt believe in it, in california, in the summer, with at least 3-4 weeks of above 100°F temperatures. So, very quickly, my brother and I, who had built matching computers, couldnt deal with the high ambient temperatures. So we bought walmart box fans, removed the side panels, and strapped them to the computers. Worked amazingly well, we later added another store bought fan to the front.
Love you gn! This was awesome. Good memories.
Corsair: let them keep testing this
Watercooling friends of GN: make them a radiator

Plenty of car rad's, but fin density and the fact that zero will be copper or brass is a bit of an issue. Sure you CAN run mixed metal loops, heck ive done it myself in the past, still not a great idea even if it is not as bad as many make out, most aio's use alluminium rads anyway but they tend to get thrown away more regularly than parts of open loop systems so nobody sees how bad they become, plus you cant see inside them without pulling them apart anyway.

All of us without AC at some point in our lives have tried using a big box floor fan on our opened PC case to help keep it cool during the summer lolol
I've been doing this as default because my case has a missing side panel haha.
Considering this is a Corsair LL fan, sets of these bad boys will probably cost the life savings of someone.
Hypothetically, what would a reasonable MSRP look like vs. the bill of materials?
Probably like $100 if they mass produce it right
Yep, not a lot, but to buy it just the size alone increases the shipping cost to like a case.
About 10 bucks, then they would charge 50-85. lol
If made with injection-molded plastic, it depends a lot on how many they think they'll sell. The tooling would be very expensive - the plastic is not.
Resin casting on the other hand is labour-intensive, so per-part minimum costs rise.
3D printing is doable but not fast, and very large 3D printers or having workers joining together many small parts are also an added expense.
There's a good reason niche products simply cost more.
Sold for 299$ and 30$ material cost.
Memes ring out, but fans resound forever.

@@AhmadAbuGdairi Maybe? I suspect the hub of a car motor would be too big for it to be the right scale though. But if the car radiator fan internals are the right size, might be a good match. Main concern is those are actually really powerful motors and I'm not sure the 3D printed fan blades would take it, you'd have to run it at a lower voltage, assuming the motor would actually work down there.
If Corsair made this into a product, let’s say a 20” box fan, I would buy it.

Would be amazing as just a floor fan in my gaming room. Epic. My daughter and dogs would just have to learn the hard way to not stick their fingers and nose in it
The reason there is that issue when you shut down the fan, is you can't back-drive a worm gear.
The reason they used one, was its the cheapest way to do a large speed stepdown, which was necessary to drive such a huge fan with such a tiny motor.
Worm gears aren't great for constant load with no oil either.. so it was a cheap solution. You can fix the back-drive issue if you add a ratchet clutch. But I'd probably just go for some other step down solution, planetary gears or precision gears.

Used to use a HAL case with a large side fan, was great for that, but it got outdated in other means and the industrial design didn't really suit my new PCs location in the livingroom.
@@Euklides_Diophant i got that HAL Case too and it was great in case of cooling but like you said its outdated itself by it size and heavynes.
You would only need one on the front and one on the back, components would never get above ambient! 😅
Interesting design. Gearmotor definitely not designed for continuous use for sure. This could be designed with a proper brushless motor for long term use. And higher speed. Imagine that running at 2000 rpm! :-D
Give it a thermal sensor and a "auto" mode that let's it speed up as the room warms up, just like the real things do... more or less
Larger fans tend to run slower, because the larger diameter means the edge of the fanblade moves through air faster at the same RPM. At some point it becomes an issue of blade strength. Though if you run half RPM at 10x the size, you are still moving a lot more air.
Continuous use yes. Slowing down to anything else but a constant speed, no. Even turning it off would strip the wormgear first time. You'd need a clutch between the wormgear and the gearbox to allow it to slip and not back drive the motor from the fan. As soon as I saw the motor when he opened it, I knew what the problem was.
This thing probably just needs a normal box fan motor instead of whatever gearbox that is
ah i see, use those brushless motors in server fans
The casual walk round and 'thud' from it being placed on the desk was hilarious..
My favourite part of this is the perfectly reproduced pebble texture on the fan body, sized up in proportion to match the larger fan size. The close-up shots almost look like macro photos, props to whoever produced the parts!
Takes cad file* Scales up* Prints*
If it were any other media outlet I highly doubt they would’ve been able to repair the fan by taking it apart, actually finding and replacing the replacement part and successfully repairing it.
Very impressed with Patrick here and I think Corsair’s probably quite happy (and relieved) that they sent it to such a resourceful team.
I guess this fan was designed for cooling down the gamers when they are playing games and when all of the exhaust heat is being blown towards the gamers causing them to overheat and throttle.
YES
Worm gears are great for large gear reductions, like when you want to use an absolutely undersized motor on a large slow device. One design feature is that because they have a very shallow thread pitch which makes it possible to create decent output torque with a very small input torque. Like pulling a sled up a very shallow incline. Another feature is that they tend to be self locking (good for a trailer Jack, but not for this), so if you try to power the system in reverse, it will not overcome the frictional forces in a smooth fashion. Like if you stopped pulling the sled, it would not slide back down the hill on its own gradually. It sounds like there was enough momentum to force the pinion or worm to rotate, but alternating between dynamic (smooth) and static (sticky) friction.
Slap a washing machine motor in there and you’ll be golden
that belt drive setup is probably in there for the reason of that motor/gearbox locking up, the belts slip, letting the fan disk spin until it stops with some pretty stiff braking once the motor stops.. that fan disk is essentially a big flywheel when it comes to it spinning/being spun
even better idea - a ceiling fan motor direct drive or 1:1
Here's Corsair's new slogan! "Corsair, when size DOES matter!" 😂
Fits with their recent line of making bigger Ds
This is excactly what i've been looking for to use as a ceilingfan, would look so awesome
wow this is an amazing idea!
@@BringbackTBC I know
I honestly thought Corsair was trying to bring in a new accessory for the "gamer" market; gamer boxfans for when your gaming PC heats up your room.
Honestly Lasko could use the competition, their prices have almost doubled and their build quality is below 3d printed gag products.
Honestly after seeing this the thought had occurred to me to upscale the models for a fan off McMaster Carr and then print out panels to fit around a box fan. Not to use as a PC fan, just to make it look like one.
@@user-dn5bx2iu3e it’s Corsair, so even if they did make it it won’t be sold for a reasonable price
I need one now fr XD
@@KontroldKaos rip that's kinda true tho
Honestly now I'm interested to see this done more.
Also fixing the issues this one has. Those being make it a single stronger pulley, and replace the motor/gearbox with something actually more suited for this project instead of locking up when shut down.
I would love to see an actual commitment into making a pc literally incorporate such a massive fan.
I think a wind tunnel style case with this being the sole fan in the whole thing would be AMAZING! Basically you just have a shroud with this in the front, that concentrates it down to the case front, and it rams air through the case out the back.
Glad to see Corsair taking initiative in the Right to Repair movement with off-the-shelf parts.
they could have done a better adaptation without that terrible gearbox, but baby steps.
Those Delta Blowie Matrons consume 4x the power of this super-sized Corsair fan. You should totally hook one up to your fan testing machine once it comes in.
As someone has already pointed here, find a single belt. For what I can tell, the motor itself does not need to be more powerful but the gearbox is going to give problems since it cannot freely move with the fan. As the fan accelerates and decelerates, the gears get al crunched down by its own teeth. There is surely a BLDC motor that can fit inside that thing and could even be programmable for PWM signal from the motherboard.
"Fixer of giant fans" has to be one of the coolest jobs in the world
would a wind turbine tech fit that job? lol
@@ToAstYNaChO its a turbine not a fan
