Those spl spikes are obviously related to the room, not the fan noise itself. They're called "room modes", basically the nodes where reflected sound waves (of the specific frequency) intersect either in phase or out of phase. In-phase modes are constructive (spl spikes) and out of phase modes are destructive (spl dips). Low frequencies are notoriously difficult to treat in a room as the physical wave lenghts are so damn long, and thus the sound absorbing material has to be really deep/thick. On the lower end of the low frequencies we're talking about several meters/yards deep/thick.

[@misatzu]

Wouldn't placing the test setup NOT in the exact middle of the chamber (which is what this looks to me) help with that to some degree? I'm thinking of distances to each wall following the principle of the golden ratio if you get my idea ...

[@shanemcconn]

I would imagine this is what is known as blade passing frequency (BPF) generated noise, which you get on axial fans. It's a function of the rpm you run a fan at and the number of blades on the fan. To get a spike at 128Hz, with 7 fan blades, the fan rpm would need to be ~1,100rpm, which sounds about right for a fan that size. The equation for BPF=(Fan RPM x Blade Qty )/60. This creates the base frequency spike and then you generally see higher harmonics of the base frequency at multiples of this (x2, x3, x4, etc), so 130Hz, 260Hz, 390Hz... and so on. The numbers don't seem to match perfectly but this is a very common phenomenon in axial fan acoustics. I see this a bit in my day job doing acoustic testing of fans in industrial cooling solutions for data centers. It's also a neat way to indirectly tell the speed a fan is going, just by looking at the sound of the fan using a frequency analyser, which these days you can just download on your phone.

think that prototype shows the basic idea to move pcb orientation to allow more airflow. this basic idea is transferred to 50 series of FE cards as well, while the custom cards still have a classic flat horizontal pcb, what explains why these coolers need the lenght. But as we have seen that prototype cooler is by far to complex and its manufacturing including that pcb layout feels very expensive. it shows what’s physically possible, not what’s economical to produce in mass. very interesting video and thanks for the work. ❤

[@tsume_akuma8321]

You know what I think. I think they exceeded their own expectations and then made a cut down version of the Cooler, eliminating the failure point of the bendy and the jank machine 90° PCIe connection. A 70°C default running temperature is acceptable, and the Standard FE Cooler is sufficient for most purposes.

I think most people do not understand the purpose of the xx90 cards in the stack.

They are literally double the tensor cores, double the AI TOPS (if you care), double the VRAM, double the power budget, and double the price of the xx80 cards. The benefit to the xx90 cards over SLI is that you can use all of the VRAM rather than both cards sharing one cards memory back in the SLI days.

Negative gates would push in electrons to break bonds and induce slight kinetic energy to change from crystal to liquid I/O states. The system would continuously absorb energy to read computations and induce energy to compute, using sums/negatives/distances of liquid/crystal computations. Multiple Vanderwaals substrate compute layers could be sandwiched together for forward or backward propagation of information. The 2D liquid/crystal Van der Waals substrates would be intermediated by gates and circuits that feed into another liquid/crystal compute substrate, utilizing tiny temperature differentials at the liquid/crystal threshold. The system would need to be sealed, and would be best to use a molecule that is conductive in one state, and not in the other state. I don't know, but sounds like a idea.

[@alexmills1329]

That thing looks awesome, I like the concept of turning the gpu cooler into a CPU tower style cooler, and I can see using it to simplify an airflow scheme in a tight fitting case environment.

[@tramapolean]

Fascinating card! I really like the thinking, especially the neat stack of display-outs 🙂

[@Some_Random_O_O]

A couple seconds in and cool gpu immediately

[@GamersNexus]

Super cool! Literally!

[@kefpull6676]

bro just think about it, 4 slot full flow through heatsink, it would be practically impossible for it to get hot

[@ikategame]

Bro, what are you trying to prove? That your GPU has better performance anxiety management than you? Congrats, your graphics card chills faster than a cheap beer, but guess what? Nobody asked how fast you can get your silicon to stop sweating. And "cool GPU immediately"? What are we, in a bad infomercial? Like it’s gonna pop up on screen: "Wow! Instant chill technology! Order now and we’ll throw in free thermal paste!" Sit down, Captain Obvious, your GPU isn’t a celebrity cooling off after paparazzi heat-it’s just doing its damn job.

[@Some_Random_O_O]

@@ikategame Wtf are you on? This is an unreleased prototype and cool tech is my hobby, piss off. I also wasn't talking about it getting cold but the fact that the pcb was in an interesting place was cool but whatever man. Get a hobby that isn't bashing people in the comments or quit whatever is making you so angry.

[@ikategame]

@ Oh, look who got all defensive over their precious prototype-Malcolm, is that you under a pseudonym? "Cool tech is my hobby," bro, congratulations on being exactly as unique as every other keyboard warrior who knows what a PCB is. You’re not special, my guy-you’re just a dude nerding out over circuit boards like the rest of us. And "piss off" as your big clapback? Groundbreaking. Truly, the Shakespeare of the comments section has graced us with his literary prowess. Also, love how you tried to twist it into me being angry while you’re here typing an essay with the energy of someone who just found a scratch on their RGB setup.

[@tackyinbention6248]

looking at what they showed for the 5090 in CES, maybe the lessons learned from this prototype was what formed the super compact double flow through cooler and tiny PCB for the 5090

[@anon7692]

19:22 I think the connector used for the 90* adapter is an FMC connector, commonly used on FPGA dev boards.

[@ANTALIFE]

I though that looked like a Samtec connector!

[@sneugler]

I'd say the pcb thickness is less to do with heat, and more to do with the extremely dense layout. You need extra layers with blind vias to connect everything with less space. Reminds me of the boards you find in test equipment. Awesome prototype!

[@andrewlee9508]

17:00 That "haiya" I can completely relate!

[@ElifHaluk]

Adaxum’s focus on real-world solutions sets it apart. Secured my position during the presale.

[@Jasontyo]

pretty amazing. this is how 4 slot coolers should be designed

[@patfre]

What’s even better is the 2 slot cooling of the 5090 which doesn’t interrupt air flow either

[@BakaDani]

The most interesting thing is that if the card that was being held on stage during the 50 series announcement is actually the 5090, then I see a lot of influence from this prototype card. If the board is in the center, away from the PCIe slot, then we probably have that same connector for the 90 degree slot on the 5090 (maybe a little different). The cooler for the 5090 was also dual flow through. I would not be surprised if they took everything they learned from this very interesting 4090 cooler and applied it and refined it to the 5090 cooler to make it impressively a 2 slot card drawing 575W. Insane. Additionally, I think there was never a Titan nor a Ti. Maybe they *tried* but found that it wasn't gonna work. At the same time, I don't work there so my guess is as good as any. I personally believe that this cooler was in development alongside the 4090. That would explain the weird markings on the die. Seriously impressive cooler though. Can't wait to see your future experiments with this cooler. Moreso though, I'm very interested in the 5090's cooler. I'd love to see if you can link this cooler and the 5090's cooler together, cause I have a feeling that there's a lot of inspiration from this prototype. As always, Thanks Steve!

[@Jeffcrocodile]

what's crazy about that cooler, is that because of the way it's designed, you could actually reuse it one a later card, like just buy the pcb for the next gen and add it to the cooler you already have.

[@zivzulander]

It would be nice to see a standard like that emerge, the way one can reuse CPU coolers. Disaggregate the GPU from the cooler. There are handful of aftermarket air coolers for graphics cards, but they aren't truly universal and can be tricky to install.

[@eliadbu]

If they changed the mounting, absolutely. But it also means that pcbs have to be similar in shape and size and dies/memories also need to be also similar in location size and height. Question is, is doable on the long run.

[@NotPointForward]

It sounds great on paper, but remember that the GPU die is not covered by any heatspreader, so that's a very fragile part there for an average user to handle.

[@hellterminator]

That's true for any GPU cooler - all they'd have to do is make a PCB with the same dimensions and component placement, just like this. Nobody's doing it, because it'd be an insane-to-impossible design constrain (what if the next generation has more VRAM? what if the GPU die is bigger? you're screwed) and the risk of customer induced damage would be huge.

[@mattkroening7964]

Those benchmarks explain a lot about the 5090FE cooler. Tons of headroom to play with, even with the amount of power the 5090 draws. It’s gonna be an interesting launch.

[@gucky4717]

I guess after testing that prototype, you are eager to test the new tiny 5090FE cooler.

[@MrAltairantares]

Cool stuff like this, taken seriously (beyond just "wow look at this!") is why I've been a patreon for several years now.

[@snwwzy]

holy cooler, 4 slots is crazy considering NVIDIA made a step backwards and did 2 with the 5090

[@EdDale44135]

The AIB cards look like 4090 cards. So only NVIDIA made the change.

[@goldenhate6649]

The 5090 is like a 3% performance boost (frame per watt). Nvidia has gone full intel, just pump ‘moar powwa’ into it and see what happens I presume overclocking nvids founders card will fry the damn thing

[@clansome]

@@goldenhate6649 Typical AMD fanboi comment. You, like me, know NOTHING about the actual performance of the card. I expect there is a firmware block to stop over/underclocking as it probably doesn't need it. Can it use stupid amounts of power, yes: does it use stupid amounts of power, we don't know yet. I expect you got your figure from Reddit or an equally reliable source on the internet.. When it's been tested and reviewed, then you can comment, you might be right. Somehow I think you're missing the point of the 5090.

[@ZackSNetwork]

@@goldenhate6649Your beyond delusional the rasterization performance is anywhere from %35-50 faster than a 4090. Not as big as a leap as the 3090 and 4090. Not as small as the 2080ti to the 1080ti.

[@cainmaxiz]

​​@@ZackSNetworkI don't usually chime in on stuff like this, but nvidias own website comparisons of frame rates does not even close support your own claims. With "raw frames" that they show to sell Dlss on the page videos for the 4090 and 5090, your looking at, on the very optimistic end, a 25%, maybe, increase in raw performance. There are videos right now explaining this much better, using footage from Nvidia explaining this.

[@milohajek]

Great episode Steve!!!

[@zivzulander]

Watch out for rogue icebergs with that thing, Captain Steve

[@baggszilla]

WOW! What a freaking video! Thanks Steve and TEAM!

[@Nihilius87]

39:07 The spikes there are most likely the fan motors, which are identical in both cards and make more noise at higher speeds.

[@GoldenEDM_2018]

Alright that's just comedically diabolical levels of THICC

[@GamersNexus]

hahaha, best descriptor

[@puciohenzap891]

XFX got nothing on this bad boy!

[@shadow7037932]

HYTE is jealous.

[@Alexander-uq2ut]

amazing video. keep it up GN! 💚

[@igorfiuza144]

They used what they learned from this prototype on the 50 series cooler. I always thought about a GPU cooler that didn't have a PCB in the way to obstruct the airflow, but they went balls to the wall with this one! Amazing engineering!

[@patfre]

Even though the pcb is not rotated in the 5090 like this one so not quite

[@TheRealLink]

What a ridiculous, insane cooler! Probably scrapped from final due to just build complexity but what a unique solution for the entire card to be 90 degrees. Wow.

[@MrWunz]

you should make a 3d scann of the cooler so someone could theoratically turn this into a cpu cooler

[@puciohenzap891]

This!

[@toseltreps1101]

3d scan your comment, print it out and send it to the museum of dumb shit

[@YouTubeDoxedMyRealName]

that connector for the PCIE foot looks like the connectors they use on the GPU boards in their data center boards.the flexible PCIE riser means in theory you could design a water block for it and screw that foot to the block parallel to the main PCB and make it single slot.

[@MetroidRTX]

This Titan design is more impressive and interesting than the 50 series design lol

[@patfre]

Why is everyone drooling over a rectangle rotated 90 degrees? The 5090 doesn’t do this and it manages to move air through it uninterrupted just like this one and that’s not impressive? That’s more impressive than just go flip it 90 degrees and call it revolutionary for no reason

[@MetroidRTX]

@@patfre My valuable opinion is better than yours, now sit down and be quiet.

@ oh your one of those who believes they are better than others when in fact your just a dumb kid. I see no reason to continue to argue with someone who believes they are the only person in the world
