RGB is DEAD. Long Live Holograms! - Coolify Holo Fans

[@coolifycool]

Hello everyone, First of all, we want to thank ShortCircuit for featuring our Holo Fan. This is our first-generation product, and we've faced numerous challenges along the way, from cost considerations to fan speed, noise control, and holographic projection quality. But we’re not discouraged! We'll take your feedback to heart, keep improving, and continue creating more innovative and fun products. Thank you so much for your support! Best regards, COOLIFY Team.

I had been thinking of something like this for years and the only thing I could find remotely close was a 92mm fan from over 15 years ago and had long since been discontinued. I'm glad to see someone with actual competency bring it to market.

[@theoldtechhandheldtinkerer4092]

I remember going to a lan party around the mid 2000's and one guy had a fan like this with just red led's, it didn't have any led's in the hub area of the fan either, just where the blades are and it would show cpu temps and other data, I guess the upgrade now is that they can show full colour video but I hope the upcoming computer software makes it possible to show data again.

[@tatemiller5514]

You can clearly see how unbalanced the fan is. That probably contributes a lot to the noise

[@Violet-ui]

0:33 That is extremely low cfm for the rpm. "Regular" fans should have around 80 cfm at that speed

[@CaptnDanLKW]

8:20 When you put a resistor cable inline, you are lowering the voltage of the logic board too, not just the fan. I bet the rear fan is running at full speed.

[@tobiasjames6949]

That wouldn't matter, like pretty much all devices an engineer knows will be connected to 8-14volts - there would be a linear voltage regulator inside that is producing 3.3 and/or 5volt for running main microprocesor, wifi etc, as long as the voltage is 5.5volts and above then the 5volt regulator will function.

[@D3nn1s]

With the low noise adapter it didnt work at all. So i doubt thats it

[@NScherdin]

@@tobiasjames6949 Its proably NOT an LDO(costs a few pennies more but you know how that goes). Most likley they run at 5v and the regulator needs +3v to regulate properly hence the 8+ volts minimum. The displays look very nice. They need to change to BLE or USB as someone said AND a few minor tweaks to run the fan from PWM inputs instead of locked and they have a winner IMHO.

They need those magnetic pin style interconnects like some of the other fan manufacturers have, and USB to connect to the system. It would be really cool if you could play a video across three fans turning the entire front panel into a screen. It would have lots of gaps of course, but you could totally use it for some interesting stuff and it's a heck of a lot less gimmicky than just strapping a screen to the AIO block.

[@marsaustralis6881]

This is old tech brought up to newer standards. For a long time, there was some cheap "LED Message" fans for both PC and USB use that allowed for very basic floating messages. The LED strips were only attached to one or two blades, but never crossed the hub. At least these can be used as floating screens of sorts, not that it looks very useful as-is. The fans really should have had a dedicated USB attachment (and basic daisy-chaining to permit controlling of each fan akin to the Lian Li LCDs) to allow direct PC control of the fans; at least pre-programmed speeds and faster updating of the displays to show off various video or still images.

[@Tarets]

Sound is typically measured at one metre (not one foot). Measuring from approx 3 times further away, would/should drop the dB figure by ~8-10dB.

[@VinLAURiA]

Ah dang, I thought these would have the images directly projected on the fan blades themselves with some rapid-refresh magic to show the patterns, quite like the Wraith Prism's USB mode. But yeah, love the concept. This would be awesome to have dynamic elements on them like RPM gauges or temperature displays. Feels like a straight upgrade over those screen-hub fans if you can pull that off, by having the entire fan area be a functional display surface. Definitely potential here.

[@RealGengarTV]

3:22 yes 20db is a lot and the db scale is log, but 3 db is only a doubling of power over a certain threshold because the scale is log.

[@erlandjohansen7195]

3dB is always a doubling (or technically multiplied by 10^0.3). A 20dB increase is 100 times (10^2.0) as much. There are no thresholds with dB, nor with any other logarithmic scale.

"You don't get 9v from a computer" DC Fan mode, it's been a thing for ages.

[@PTRRanger951]

Typically you don’t get 9v from a computer. He is correct. You can get DC fans that operate in different voltage ranges. But a two wire connection like this fan is and not a PMW, you are going to strictly use 12v. Or it will be from a molex connector which will also be strictly 12v. A PMW fan is one you can alter the voltage which will increase or decrease the speed of the fan. A DC fan is made to operate at a certain voltage, operating and a higher or lower voltage will create electrical noise and the higher the voltage, the more you risk burning out the motor from over voltage.

[@sarahjrandomnumbers]

​@@PTRRanger951 word word words. I'm aware of all that, which is why I said DC Fan mode. That implies I know about PWM, and it being 12v and everything else you said.

[@tobiasjames6949]

@@PTRRanger951 A PWM fan does not alter the voltage level, it alters time between on and off for the 12volts, hence PWM. DC fan head control has been around for ever, maybe dissapearing from motherboards to reduce the need for large mosfets near the fan header but still was used in some use cases - the platform chip connected via SMbus would determine what sort of control could be set - i did this back in C2D e8400 days where I had silverstone case fans that were all 3 wire, and the only PWM was the CPU fan itself. Unfortuniatly these days, it seems platform control chips are hampered from factory - relying on crappy bios curves to control the fans instead of being able to control it properly with software, one the of best is Speedfan.exe where I have one setup that GPU die temp can be used to automate case fans.

[@PTRRanger951]

@@sarahjrandomnumbershowever what you said was wrong. You actually do not get 9v from a computer. You get 12v. You need a controller to change the voltage, therefore it’s coming from a controller, not the computer.

[@Blaze6108]

So the idea of reusing the spinning that your product already does inherently to run a persistence display is actually really cool, and perhaps in the future it will be possible to put the LEDs directly on the edge of a pair of blades. This implementation isn't great, but for people who want a fancy PC I can see the cool factor being worth it, especially with improvement. For the issue of the image breaking on variable RPM and the difficulty of fixing it, they could consider operating the fan at fixed speeds by interpreting a PWM signal instead of using it as-is; Corsair's maglev fans already do this, as they will refuse to go below a certain RPM since the technology wouldn't work. For control, if putting a USB port on each fan is not feasible, there are two options: abuse the F out of PWM to send signals, or to make it fancy, integrate a somewhat powerful NFC tag near the hub that allows the user to program the fan by proximity without having to outright touch it (NFC can work at up to 10cm). While bandwidth and tag storage are a limit, an active tag could transfer the data to the fan in realtime, and the images have to be like 96x96 pixels anyways so they won't be that large. Alternatively NFC can be used to bootstrap a Bluetooth connection without needing the user to mess around (wi-fi for this is ridiculous).

[@SuspiciousFish144]

[@hhidd]

love the idea, as everyone is saying it does need improvement but i'm 1000% getting some of these in the future when they get ironed out some more (whether its from coolify or if a reputable brand uses the idea) the hologram effect is wonderfully cyberpunk and has so much potential, especially if they can sync up with each other (think like, a dragon or something flying between them)

Noise tests are normally done from 1M away and not 1ft. Should be more than 3 times the distance so that's not accurate, additionally the PC behind it is on which clearly shouldn't be if you want a fair reading. The stats of the Noise for the fan will be measured at 1M and not 30 cms

Can't wait to see how these and competitors' versions turn out. Not usually impressed by gimmicks but I would love holo fans on the front of my case. I went from being an RGB fan to not a couple of years ago, and now I'm kind of back into it again. Definitely keeping an eye on this

[@godchi1dvonsteuben770]

@ 3:11 doing a decibel test with ambient noise, then deducting the ambient noise level from the total noise level, isn't accurate. Rig up a remote power source and test the fan alone.

[@timderks5960]

Exactly, that's not how noise works. IIRC, when there's more than 10 dBA difference between two noise makers, the loudest one will completely cover the other one. When there's less than 10 dBA difference, they both provide some noise to the total, but I'm not sure anymore how to calculate it.

[@leeroyjenkins0]

It's definitely not an order of 20 db error though

[@MZzXzZM]

Not sure if it's due to the camera angle. It looked like the fan was blowing air into the dB meter.

[@CodeDonut]

he was talking straight over that noise test also.. lmao

[@milamber3312345]

"doing a decibel test with ambient noise, then deducting the ambient noise level from the total noise level, isn't accurate." - He didn't 'deduct' anything. As one of the other commenters says, from 10dBA extra up it's effectively all just the loudest noise source. They measured the noise floor at 43dBA and the fan at 53dBA. That's right on that 10dBA threshold. So the fan is 53dBA with or without other noise sources. They would only need to do a more rigorous test to find out the accurate value as you suggest if it had been closer to the noise floor of 43dBA, but honestly any reading over the noise floor at all would be a solid indicator that it was noticeably above the claimed 33dBA. Because if it was only generating 33dBA of noise, the noise floor at 43dBA would be totally drowning it out, being again right on that 10dBA threshold.

[@turtledovechen176]

I thought they would actually be holograms, like 3d n shit, but it's just a rotating one dimensional array of leds, which doesn't roll off the tongue as well I suppose.

[@statixfear]

A pretty cool concept and arguably cheaper than adding screens to your PC aesthetic. It just needs one of the more reputable brands to adapt it and refine it a bit more before releasing to the market.

[@Lovedbychrist1]

Uh. These existed about 15 years ago, and they were usb controlled (they still were terrible to work with). I don’t remember what they were called but they cost $80 each in 2010 money and the fan performance was equivalent to a $2 fan. Edit: they also only showed a prebaked image or text. It was 2010.

[@TheRealVulle]

I remember having fans like this in the early 2000s. Fun to see them back again.

[@Reahreic]

I saw an awesome display like this in the Keflavik airport security queue, it was about the size of a small child and was awesome.

[@NScherdin]

I would guess, the image is synced to the BLDC driver in the fan. But when you physically interrupt the fan blades the BLDC driver has to resync, so the image goes wonky. Understandable. The fact it works down to 9v indicates this is likely the case. Also going to low on voltage is probably an issue with that many RGB Leds being driven if they didnt design it to run at those lower voltages. Probably willl fix it by putting a boost regulator in the display side, and adding a PWM pin would be pretty simple. Best looking persistence of vision display I've seen in a long while. Especially the full color images(or you are much better at videoing them than others have been :) ).

[@t3h51d3w1nd3r]

Ok, so they're not 100% there yet but the idea is awesome, they just need a bit of refinement and the rear one shows they can do it. Like everyone is saying a pwn signal and a better app and it's gold. Hopefully there's an easy way to make custom vids, who wouldn't want a logo, or symbol for theme builds. I'm trying to do a star trek build atm, even just one these fans with the starfleet logo would look awesome.

[@Rudy2k5]

I think it will be a trend for a year or two and that's it. They are more expensive than regular/better fans and there's no real purpose for it. I think they will start to annoy people after a while.

[@ZeeeGamer]

Don't defend RGB we wanted holograms from the get-go from day one

[@gabiballetje]

Seen how this tech has been around for some time now and there are multiple such holo "screens" around, it was a matter of time before it would end up on a fan. And honestly, i don't mind it. I mean, the Lian Li fans with screens are awesome, the infinity RGB on the side is also very cool, but they're expensive, and frankly, this holo idea might just look even more futuristic, depending on your build it might fit even better, especially if you have a Cyberpunk or general mech or high tech theme in your case or something. And you can do funny stuff with this "screen" all the same, but now bigger. Unless you have a dedicated screen in your case already, but this being on a fan, yeah, i kind of like it. A newer version with maybe better fan speed control, mostly for noise, would be cool, also, i still kind of would prefer software for my PC to run this, to upload whatever you want it to show, i want it to not be as shady as sideloading an app, and i have an iPhone, but yeah, that software can also be shady, and too many of those programs can drain a lot of resources compared to what it does, which is a shame. In any case, that clearly needs some more work, buuuuut, if they get this done right, they might sell a lot of these, depending on the price. I wouldn't mind them.

[@bluephreakr]

This makes me wonder now, if the holographic performance would do better if the lighting was handled by the same number of LEDs interspersed around the circumference of the fan rather than a straight line. That may reduce image distortion between fan speed adjustments, and if the fans were able to be attached via USB for the data stream then it could act as a USB-attached display. If Coolify wants to make this _even cooler_ they could have fans attached via USB and mandate use of a USB-attached type-E USB type-C hub to redirect the mainboard type-E connection into that with a short length of E-to-E cable, then have the type-E cable from a case's front panel be attached to the hub's other type-E socket.

[@1405dic]

For the led vs hologram, maybe hologram on fan is a sweet spot of pricing vs sizing. Cuz if you imagine a giant fan to display image, it would make no sense.

[@bluephreakr]

@@1405dic That's uh, not exactly what I meant. Maybe I needed to clarify; there would still be the need to create a functional fan, but the fan could have LEDs which spiral out from the centre. Not sure how they'd be able to do it, but the way this is done presently would exhibit challenges on PWM control where a spiral layout would… _less_ if the math were adjusted per-LED.

[@leftcoastbeard]

You'd think that the POV math would work with the Tach signal or a hall-effect rotary encoder built in, so that no matter how fast it spins it would always render the same image.

I wonder if a spinning line of LEDs: 1) Is a hologram 2) Has better resolution than a whole screen 3) Requires more power to get spinning because of increased mass

[@MajinOthinus]

1) No, but most people have no idea what a hologram actually is anyway. 2) Most assuredly not in this case - well depending on your screen anyway. Though you could probably do better. Interestingly, your angular resolution depends on your refresh rate with this technique (your radial resolution is just the pixel distance as usual); with some really high refresh rates you might get some really high angular resolution - though that'd make the thing very sensitive and thus expensive, not to mention incredibly loud. 3) Obviously.

Cool idea! Now let's wait and see what Noctua will make with this.

[@WilliamNeacy]

Saw the thumbnail and thought it was a scam. After seeing it in action, I'm kind of impressed. It's got potential. Not there yet though

[@pitmaster226]

3:21 isn’t 10 db the threshold for “double volume” while 3db is a much more scientific measurement? Feel like whichever number you use you’d have people telling you you’re wrong, but I think 10 is more correct if you’re talking about the perceived volume of a fan

[@DauntlessDH]

Once they work out all the kinks I could totally see using these in my next build.

[@TulgaD5]

4:47 he's adapting.... 6:24 the repairman

[@kobby2g8]

Saying 'Not a fan of 8' while talking about a fan literally displaying an 8 and not acknowledging the double pun, was a huge missed opportunity.

[@davidjensen7922]

The way Alex opened that box makes me think he's been watching too many AvE videos.

[@satakrionkryptomortis]

imagine those working as promised. and being able to sync a row or column of them to display corresponding sized pictures or gifs of linus.

[@techxbd]

really cool! i see CPU and GPU temp along with CPU/GPU Usage on different fans in the future.

[@theoldtechhandheldtinkerer4092]

Oh wow, persistence of vision fans are back!!! I remember these from the 2000's.

[@TheRealVulle]

Look up the Thermaltake Cyclo LED fan from 2006 or 2007. Same concept. Funny to see those types of fans coming back.

[@RiddleTime]

6:00 why not use a few rubber vibration dampeners or washers instead of ruining a case?

[@TwoTeaTee]

Vessi sponsor money!

[@Waffls]

Because Alex

[@lordjerle8481]

Alright, no more caffeine before using box knives. That bit legit had me worried.

[@ncolvin05]

Can we just have LTT follow up should coolify bring out a gen 2? Would love to see what they do and I'm already considering getting this version anyways. Also, imagine being able to transplant the fans and their necessary components onto your gpu fans. Freaking awesome

[@ColdestLivewire]

Why WiFi? - If they were usb you could use it as a resource manager, I would totaly have rings representing cpu/gpu load and ram usage

[@xypha85]

bio can still change that speed, pwm is just preferred, but volt change was the previous version and is still present in most bios and boards..

[@irishRocker1]

As soon as I saw the led part in the middle I thought "that's gonna generate noise". Would have been nice to see if removing the plastic bits improved noise or made it worse.

[@justmechanicthings]

I can already imagine the cursed imagery and memes people will be applying to these

[@jubuttib]

1:59 You can obviously have speed control via voltage with just two leads on a normal fan, but you can't read the RPM (2 leads = power and ground, 3 leads = added rpm readout, 4 leads = RPM + added PWM control signal, usually), and of course the internal electronics of the fan (which fans like this have in spades because of the display etc.) might just say "nyet" if you try to run it undervolted. This one seems to be multivoltage tho, nice.

[@ms3862]

Hologram only works at 2600rpm, lower the rpm and you'll just have an RGB fan and no more hologram

[@jubuttib]

@@ms3862 The video already shows it working at a lower speed (it gets quieter at 9 volts because it's spinning slower). If the software knows how fast the LED spinner is rotating, it can time the color changes to compensate. At lower speeds maintaining motion resolution gets harder, and if you go way too low the persistence of vision part starts to break down, but you don't need 2600 rpm for it to work OK. Some holographic fans spin as slow as 400 rpm.

[@benwu7980]

They do seem to have potential, but the connection issue is weird. Would also need a sync feature for particular fan groups, like to have the front ones each playing a portion of a video.

[@karrotop]

Cool idea, but yea, definitely needs some further refinement. I'd unironically get a couple

[@magnushegh582]

6 dB is a doubling of sound pressure. 20 dB is multiplying by 10 (20*log10(10) = 20)

[@PuOop-j9l]

The next step for Cases will be toollles fan/radiator mounting

[@Etherel15]

Yes, having to use my phone to setup a component that is hardwired in my PC. Yes, we have reached that height of 2024.

[@Omega_Mark]

Someone doesn't know that the last couple of years motherboards can control 2-pin fans. You just have to set them up manually in BIOS.

[@tomc.2706]

I'll wait for Gen 3 of these to make use of them in Cosplays

[@CaptainBeardsome]

These fans are awesome, but they are indeed janky. No thank you.
