- Using Schlieren photography techniques, we're able to show NVIDIA RTX 3080 Founders Edition airflow paths and behaviors. This is new to us, and we have a lot to learn for the future.

Thank you for 1 million subscribers! It's been a crazy ~13 years since we started the website, and a crazy 11 on CZcams).
Look at this airflowtograph. In this video, we're using our new Schlieren photography setup for the first time to take images of the airflow pattern of the RTX 3080 Founders card, as we're able to take images of the density gradient of the air. As stated above, this is the first time we've done this, so we still have a lot to learn. Some things we'd like to improve in the future would involve a separate lens for our high-speed camera, so that we can get enough of a zoom to take these images (the focal point is 10 feet away from the mirror!). Other improvements would be additional card comparisons, potential custom glass enclosures to somewhat simulate a PC case surrounding the cards, and just more experience for better analysis. We'll get there -- give us time -- but this was a fun introductory test case with a lot of interesting airflow patterns.

Keep the content coming!
Yes, great work Steve ! 👍😊
You gonna do one that shows it in a case?
So awesome, i hope enough people want to learn more about airflow imagining so you can get a better camera
Very interesting video.
For laser optics we call those mirror mounts Kinematic mounts. And that is the largest one I have ever seen XD
Haha, yeah, thanks for that reminder. I knew the name when I bought it and then promptly forgot it! It was very expensive.
Is it similar to how we can perceive heated air movement on a road at bright sunny noon? Like how the change in air density/ pressure(?) bend the light? A real life analogy would be nice.
@@zabuza8548 it sounds like it is similar just a f*ck ton higher tech
@@zabuza8548 Yes, it is similar! There are quite a few interesting effects visible in air caused by differences in air temperature. Convection can be thought of a being caused by pockets of varying pressure (with hotter pockets having a lower pressure), so that by Archimede's Principle, the lower pressure pockets rise to the top while the higher pressure pockets sink.
How does varying air pressure affect light? Well, light actually travels at different speeds at different air pressures! (The cause is a little complicated and is probably best to not explain here.) This means that, when the light hits a boundary between a higher pressure pocket and a lower pressure pocket, light travels at a different speed, and this results in a 'bending' of the light. (See 'Snell's Law for more info.)
Additionally, at this boundary, light can actually be reflected! This is why, on hot days, you will sometimes see the sky on the road instead of the road - you're seeing this reflected light! These same things can also be seen in sound - if you have a train nearby, you may have noticed that, on really cold nights, that the train sounds MUCH louder than it usually does. This is because on these nights, the temperature drops a lot as you go up even a few hundred feet. The sound waves are reflecting off the colder layers on top, meaning that more 'sound waves' reach your ear.
@@zabuza8548 Yes, road-shimmer is created by the exact same effect. You have layers of air with different temperatures, thus different densities, causing diffraction which bends the light. There's a few great videos going into detail on Schlieren imaging on the Veritasium channel: Intro - czcams.com/video/4tgOyU34D44/video.html and With Color - czcams.com/video/K7pQsR8WFSo/video.html
This chanel is a good exemple of how much your love for something could bring you to do more than others, but just because you like it that much.

the tech youtuber space is filled with such a wide variety of people. sometimes I find new product launches really discouraging. seeing "reviewers" basically doing marketing work, blatantly repeating manufacturer claims and whatnot. But seeing innovative content is very refreshing.
Translation "we got this huge block to house the mirror in, this way, if linus ever comes round, we don't have to hold our breathe for the entirety of his visit" XD
Does he dislike Linus or something? What's the history?
@@BlackAus07 linus is notorious for dropping shit. Therefore, you wouldn't want Linus around very expensive pieces of glass
Yeah Linus drop Tips, I Bett you heared it at least once
Are different in many ways. GN focus on data, real testing, tools, community hardware questions, ask for support via merch.
Linus sells shit, inject adds left and right, focus on what he can produce to push a product to his audience... and is jelous of GN credibility.
GN and LTT have absolutely nothing against each other , my comment was a joke about Linus always dropping stuff. They create and provide different types and styles of review on tech products. Personally I dont see either as better than the other but just different, and thats a good thing, diversity is the spice of life imo. Anyway, I digress, thats just MYtwocents ;)
Normal people spending Patreon money: personal goods
Gamers Nexus: we need this to see air
i love how these guys goes into and talks about every little detail. most other channels will just throw up a benchmark, a few graphs and call it a day.
lol for reeeeeals, greatness.
Steve we absolutely need you to do this on the triple "downdraft" style coolers. Very interesting info for all types of coolers. Cpu, gpu, cases, fans, everthing.
Yeee i was about to ask the same.
This exact same setup, just trade the card for... i dont know, an open shroud like the ASUS tuf, or a closed triple like the EVGA they overclocked recently in a stream.
Im guessing the lower portion of the "chassis" gets toasty with trapped air, requiring a really strong fan mounted at the front of case.
But thats just the hypothesis. And GN are just the guys to test it. This setup is so cool im nerding out lol
This gave me such a kick. 😀 in 1981 I did my sixth grade science fair project on schlieren photography. Keep it up!👍
Re: "I did my sixth grade science fair project on Schlieren photography" - so cool! That's a great project. Did you use multiple mirrors or one?

That's $million idea right there: A Gaming Mirror.
As a gamer and an optics professional, this is some of the coolest (heh) content I’ve seen from this channel, nice job!
One minor nit to pick: Radiative heat is heat which is transferred via radiation (aka light - typically mostly infrared). This is the heat that is detected by a thermal camera. The heat coming off the back of the card in these videos has been conducted from the GPU and other components and is now transferring to the air via convection (leading to refractive index changes as you explained). Typically, radiative heat transfer is totally negligible unless you’re in a vacuum - it is conduction and convection that are the vehicles of heat transfer within a computer.
Thanks!
also another nit pick: every time he mentions "heat rising". he would be more correct to be saying "hot air" naturally rises, heat transfers wherever there's a difference in temperature irrespective of direction
everyone: what?
this guy: YES! but also this.
gamers nexus: you're hired.
YES thanks! :D Steve talked so much about radiation i was twitching compulsively by the end of the video. XD
Also, I just learned some more english here ^^ : heat being "transferred away via convection" is heat being "conveyed away"... There. 'Thought it might help y'all not saying "convicted" (nothing illegal in there) or "convectionned" wich isn't a word. u.u
And since we are nit picking : radiation is still very small and still looks negligeable in a vaccum but it's simply the only way to transfer heat... gues I wanted to make that clearererer
Also, thanks Gamers Nexus, amazing video nonetheless. Shlieren imaging is awesome!
If we really want to get technical, what Steve is calling "radiation" in this video would be best described as "natural convection," as opposed to the "forced convection" that occurs when the fans are running.
Of course, the fact that the term "radiator" is really a misnomer probably contributes a lot to why people get this distinction wrong, but I suppose that "water to air convective heat exchanger" doesn't exactly roll off the tongue.
I demand a heat map of Snowflake.
I'm likely producing the same heat map as a normal person.
There would be several hotspots in their face especially around mouth and eyes
And one huge coldspot in crotch area
Oregon, Kinosha protesters and I forget the other hotspots with snowflakes🙃

The most scientific review of a VGA on CZcams! So Sick!!
GN needs an award for the most nerd flags triggered in a GPU review.
Shame though they still don't actually understand heat transfer. They talk about radiative heat all the time, but that's very insignificant here
9:45 that stargate reference makes me really happy lol. I'm actually rewatching SG-1 right now believe it or not
Please do fan reviews with this!
"Impact of RGB rings on fan efficiency" would be a really welcome study. If GN could push companies to make at least a couple high-efficiency RGB fans which did not sacrifice too much for the bling, that'd be great. Have our fans and eat them too, if you will.
@@Lishtenbird what if you made a company adding rgb to noctura fans?

You've spent all this money on fancy mirrors and lights, meanwhile I've just been blowing vape into my case.
lmao.
@@on-quest air is moisture suspended in air, so ¯\_(ツ)_/¯
@@on-quest I'm just stirrin the pot my dude. I'm aware its not the greatest idea.
Its not the water vapor that's the issue. Vape from an ecig will leave a VG residue which will collect muck and affect cooling. If you aren't doing it all the time it's probably no big deal though. Source: ran a vape shop for 6 years and game excessively
I've been taking bong hits :P
I would love for you guys to do more of this. Schlieren photography is interesting on its' own, but there are a lot of potential insights to be had with what you're doing here, given the constant influx of new products. You're next-level.
Watching a 30 minute video on air flow on a card I can't even get. Niiiice.
nrlift we definitely have too much spare time ;)
Is it not available where you are at?
This kind of thing, oversciencing the shit out of cumputer components, is why I'm subscribed, and why I bought from the GN shop! Love your content, guys!
They are freakin insane and so awesome!
same 👌
VERY late comment, but having an Aerospace Engineering degree and having used Schlieren, so cool to see it used here! Such a great way to show the ailrflow that I never would have expected to see used for something like this! Granted, we used it for looking at shock-waves in supersonic airflow since you can get a lot of info from the angle/shape of the shock-waves.
As an ex-physicist who worked in optics, HOLY SHIT THAT KINEMATIC MIRROR, JESUS CHRIST. :O
I've been helping to build and refine one of these setups for my physics department to use in demos. Really cool to see an example of real world use.
You should check out SmarterEveryday, he just recently used schlieren high-speed photography and some math to calculate the speed of his supersonic baseball cannon. That's probably closer to the physics department's use-case.
Been waiting to see this!! Awesome work guys
I work in Optics manufacturing and we use high end lasers and mirrors and aware of how expensive the equipment is. I can appreciate that you spend the money to bring one of a kind content. Thanks GN team!
It's fun to see how excited you are about this new test setup !!! So cool!
This is a one-of-a-kind video. So unique and so helpful! Thank you for investing your time and money with this!
Do you all have the FE PCB tear down video? Really looking forward to that review after watching other partner tear downs.
Working on it right now!

This video is amazing! Thank you for putting this together! It's so awesome seeing our donations directly improving the quality of testing equipment and the scope of these videos! This channel just keeps getting better.
Seriously bad-butt content. You guys always find out how to get more metrics / data-points / information that I never knew I wanted. Love the effort you guys put into your videos, keep it up!
Man, that footage is awesome !
Great video, love that kind of tech deep dive !
Thank you!
About the case/CPU fan above the rear fan (22:25)
In HVAC (I'm an engineer) there is this phenomenon called the induction of air. (hard to find on internet, because you get other stuff)
When you blow air in a certain direction, especially with jets, you get a funnel of air pushed in certain direction. Because of venturi, the surrounding air is sucked into the jet of air, so the jet gets bigger. Next, you'll get around the jet of air also airflow in the same direction as the jet. As an effect you'll get airflow through AND next to the fan in the same direction.
That's why the air funnel is not only go through the fan, but also next to it.
This channel should’ve hit 1 million subs ages ago. I’m happy that you guys are getting noticed because your content is superb.
This setup is a great addition to your setup, really helps visualize the airflow. As always GN moving further and further away from other outlets with how high the quality is
STARGATE REFERENCE! Yesssssssss. We need you to help lead the campaign to bring back stargate Steve. BE OUR SAVIOR!
I believe they're working on a new series. It's not a reboot, but a continuation!
Ok ian.
Indeed!.
@@thegreateaden Yes! I heard. So excited. Savior Steve could marshal his 1 million subscribers to tweet at mgm or appletv or amazon or someone for a bring it back campaign. I'd be stoked.
@@thegreateaden Are you reprising your role as Daniel again? :)
Oh my gosh. How can anyone not love this channel... coming up with this kind of stuff? thank you T.Jesus and staff!
This is why you guys are the channel I check for reviews and info before I buy something. Always a step ahead of the competition, getting more data and explaining it to morons like me.
The scientific focus content you guys create is amazing. Very unique for this genre.
As the channel continues to grow and grow, they are taking the testing to a level that is insane and ultimately beneficial to the computer building community.
Fantastic testing Steve, and it gives us so much to think about re case airflow. As a R&D engineer in the field of airflow development within internal comustion engines (inlet & exhaust ports), these images show to me that some kind of shroud on the lower side, between the two fans, would help airflow and aid cooling. Also, at about 25 mins in, one can see the 'intake' fan to the right is causing issues by blowing over the intake of the rear fan and causing air(heat) to be drawn downwards out of the the cooler, working against the the fan trying to pull air upwards. Great work.
Fascinating. Airflow and heat dispersion is of particular interest to me. I approach each of my own builds very focused on this and related matters. More content like this would be appreciated.
Thank you.
So you’re telling me this testing is using smoke and mirrors?
just mirrors, don't wanna get whooshed, but some people might think they are using smoke, you can find great videos on CZcams explaining how this kind of imaging works
@@davidrajchman7162 damn so close for that joke to work.
I'd actually like to see them use a fog machine or a gas like helium or argon streaming into the fan with the Schlieren setup. After watching the footage a few times it doesn't seem right. Like the imaging isn't accurately capturing the velocity of most of the air the fan is moving, it's only capturing the heat and turbulent air. I'm no expert but my guess is the refractive difference in the air that is closer to laminar flow is low enough where it isn't captured.
@@cincybeck maybe, but what makes you think that air being pushed around by a fan that's causing hot and room temperature air to mix would be laminar? Especially when coming off such a weird surface?
@@cincybeck this way you could not see pressure variation but airflow direction (and speed maybe), which is a different thing.
This got me so excited (physics graduate). Thank you so much for the great content! I can not stress enough how much better than the average CZcams video this is. Looking forward to more Schlieren :D
i'm just an 'arm chair' scientist but when i saw Nvidia's claim, i thought about Schlieren photography proving if it would flow that way, ect; and was pleasantly surprised when i found out GN was going after the same question i had. nvidia should have done what GN is doing, instead of making a simplified graphic of what they hope the heat is doing.
Can't believe you guys went full Schlieren, too cool. Also, whoever said "let's film you talking about the mirror THROUGH the mirror" gets a high-five.
This is by far the coolest and most pertinent pc enthusiast video I've seen for current content. I cant wait to see you guys use these tools regularly!
I know this is an odd question, but I make mirrors like this as a hobby. What specs are your mirror?
60-40 surface quality, f/6 aperture, 10 +0.06/-0 in diameter, coating spec Ravg greater than 85% at 400-700nm, greater than 90% at 400-2000nm. 44.5mm edge thickness, 0.3J/cm2 at 532nm energy density limit, 1064nm, 10ns. surface accuracy λ/8 , coated with protected aluminum.
@@GamersNexus Totally impractical and I'm not knowledgeable enough in mirror manufacturing to guess but, I'm really wondering if this mirror could double as a telescope with a custom shroud and a standard set of eye pieces and EQ mount. f/6 is prime. I've got a Takahashi FSQ-106EDX4 f/5 106mm. This is really cool stuff, man!
Specs of a mirror, that is actually the most shocking thing I've heard, TIL there are actual specifications for a mirror, thanks for this tidbit of information, I will only use it for good, I swear.
@@Killerjerick There are specs for everything... EVERYTHING!
Gamers Nexus I’ve got a mirror too! I’d say it’s about ‘yay’ big and it’s quite shiny.
Last time I was this early the 3080 was in stock
So you were never early then, since it was never in stock xD
I used schlieren imaging when learning about supersonic nozzles at university, during my aeronautical engineering degree. Fantastic.
I have only seen this kind of photography once and it was in a wind tunnel for studying aerodynamics (demonstration for air force cadets) ! You guys are far and beyond any other tech channel ! Kudos for the most scientific analysis available out there ....
This is the quality content I subscribe for!
Only Gamers Nexus could dissect photons with a simple razor and tweezers

@@earthtaurus5515 very true
The fact that you guys did color split filtering is awesome!
This is some of the Coolest stuff I've seen any Tech Reviewer Attempt to Cover! I've personally had an Image in my Head of what I would assume to be the Basic Air flow, but to really be able to see it like this is so Cool!! It's WAY more chaotic than I thought, but also something about seeing the airflow patterns with different fan positions was really Enlightening!! Great work Guys and Work really love seeing More of this for Sure!! Case Fans, Other GPUs, Even maybe some Tower coolers if Possible!
The video mentions imaging limitations with the current setup that you can probably work around by fine-tuning simpler test methodology. Smoke testing is pretty common to visualize airflow in HVAC systems, wind tunnels, and car repair. Here's one of the better links I could find for enclosed flow: czcams.com/video/XRXZ8BZ1rDE/video.html
Smoke testing might have been something you avoided here because it seems low-tech and limited at first glance, but the quality of the result depends a lot on how much time you put into it. A well-done setup can produce really detailed, professional results, although the most detail comes from varying the introduction point.
The trick is that you need to have a good-quality source of dense smoke that comes out of a nozzle as laminar flow. Lighting can also make a big difference - the best images use light scattered from a source perpendicular to the camera angle: czcams.com/video/_q6ozALzkF4/video.html
Bump, Smoke testing is amazing.
Don't quote me on this, but iirc in the previous video on this setup they mentioned they gave some kind of smoke a shot a long time ago but whatever they used made the parts stink like hell. It's in their channel somewhere.
@@medec10667 Good smoke setups are either proplene glycol based or CO2, neither of which have any odor.
PG will leave residue after long enough, but it takes a real long time.
@@louisvaught2495 And the residue usually comes off with alcohol, something that you use anyways when it comes time to dust your pc....
PG based essentially means its vape (which is basically how we tested our homemade solder sucker repair desks for work.... my boss literally asked me to vape right next to them for a worst case scenario, lol)..... I can tell you from personal experience that with good airflow: it literally takes months of constant exposure to leave the easy to clean residue behind.
CO2 smoke testing sounds interesting. I wonder if they would cause temperature discrepancies though, not to mention the suffocation risk....
@@louisvaught2495 Dont know if you can get such a detailed image with smoke. Also would assume that smoke is more appropriate to visualize fast airflow on larger surfaces (like a car) vs heat slowly rising from a gpu in a more dense computer case.
man this channel deserve more subs. engineering at its finest
I have to say, it's *great* to FINALLY see this on here! I have been making comments here, at LTT and several other non-tech channels for Schlieren imaging for at least 4 or 5 years now. I feel confident this will be a really useful tool in the arsenal! 👍
ALWAYS wanted to see airflow this way. Glad you guys made the video
Generic tech youtuber looking at the simple, impossible straight lines shown by nvidia in their presentation: oh no cpu hot
GamersNexus: *actually*
Holy shit I swore you guys were 600k subs the other week. Congrats GN!
This is UNBELIEVABLY cool!
The most surprising thing for me is how wide angle that right fan throws the air. I’m not even sure how it’s doing that. It’s like 180 degree dispersion.
I also love all the littler vortices you can see spinning up and dissipating.
Can even see how the heat radiates off each individual fin!
This was way cooler and far more educational than I thought it would be. Kick ass job, guys!
Love the new intro! Steve is still humble as usual!
Get ahold of Destin from SmarterEveryDay. He'd probably get a kick out of this
Launch a 3090 out the air cannon
True, Destin is really good at this kind of photography. With the equipment that they have, he might have some really good ideas on how to expand and improve this setup.
No laminar flow, no deal.
@@nospoiler9550 Get Derek from Veritasium, he loves turbulent flow
Love this kind of content... did mostly what I thought it would do... especially once you added the "front" and "rear" fans to simulate air flow in a case. This was really fun to see!
In Depth research like this is why I'm subbed. Great work as always Steve!
I was hoping that the methodology for this was Steve putting his hair over the fan/s to see the displacement of hair.
steve looks like he is presenting this as an invention to his class
Doing some on the side SI work (paid even!) and man, has upgrading my workspace given me a new appreciation for both that work table and your whole set.
Love seeing practical applications of optics outside of research! As always, super thorough prep and setup. :)
"How much did that mirror/housing cost?"

@@generalbacon7476 heh niceeee
Amazing Video. Thank you Steve and GN staff!
A lot of this is way above my head but still so cool to watch! Awesome work everyone at GN.
I would love to see a GPU with a regular downdraft cooler in this setup if it’s feasible
Hey Steve love the videos im a mechanical guy and just a quick question you sure its one micron adjustment? I've worked in high precision applications so I was wondering
I assumed they just replicated what was on micrometers (same screw thread pattern, just scaled) really.
@@afelias oh course. but still I was confused when he said one micron our machine with nanometer technology cost a fortune and we can't repeat one micron
@@MathKiller1195 Cost gets complicated because the setup is for an expensive mirror. So it's probably about validation while also minimizing undue force to the mirror.
They probably just made sure it's accurate to the micron and stopped.
I was so excited when I saw you guys were going to do this. Once I saw it on my feed I was almost giddy! Such a cool concept put to practical use.
I cant wait to see how this project evolves!
What a fascinating setup, and I look forward to seeing what you do with it and what sort of insights you'll be able to extract. As an amateur astronomer, it's really neat seeing this equipment as it's closely related to the construction of reflecting telescopes for astronomical use. In fact, the air currents inside and in front of such a telescope can be imaged similarly by pointing the telescope at a bright star (equivalent to your point light source) and defocusing the telescope to produce a large "disk" of illumination in the eyepiece instead of the sharp dot you'd normally want. Holding my hand up in front of the tube is clearly visible, and you can see the thermal gradients emanating from it. Neat stuff!
G'day Steve,
😲WOW! that was Awesome, this & Romans Micro CPU Imaging has blown me away this week,

'Ryzen Nano-Structures more than 100,000 times magnified. Visiting Tescan Part 2/3'
'14nm and 7nm are NOT what you think it is - Visiting Tescan Part 3/3"
Roman also did a Intel 14nm one last year, but I haven't had time to find that yet, it was before I started consistently watching his content so not sure how long ago it was
Steve: "New very expensive parabolic mirror we just bought"
Me: Looks at the hair... "Sure Steve... You just pulled that off your bathroom wall didn't you?"
Your commitment to improving since day 1 is not only admirable, but truly astonishing in this disposable world. Congratulations and thanks for all the money you have saved this fool. Cheers and onward to 10 million!
You missed your calling as an Engineer Steve. (Seriously) You have the brains, drive, and attention to detail. Good work.
My paper edition 3080 stays at room temperature even under full load.
Can you beat that?
Very interesting piece, but I have spotted a slight issue: What you call "natural radiation" is a misnomer. You can't see radiation with a Schlieren setup, since radiation goes straight through air without moving it. A Schlieren setup shows different kinds of air movement i.e. convection. Either natural convection, when no fans are involved or mixed convection when fans are involved to help natural convection, but natural convection is not negligible or forced convection when natural convection is negligible and all air flow is dominated by the fans.
This is one of those videos I feel I really need to watch more than once.
This is definitely one of the best videos you guys have made. Thank you for your hard work and dedication to good testing!
Meanwhile Jay: Welcome to my next video of reacting to subscriber PCs!
Apparently that's the trick to have 3 million subs. 🙄
This next one is from GNSteve. I like the cool mirror effect but your cable management sucks. Also not a fan of the red, can you change that gel to a violet one?
I love nerding out with you, man. Great video, that testing rig is beautiful!! Each piece of blue tape served a purpose and did a job- it's a function over form situation, and awesome in its own respect.
This is hands down one of the most interesting Video Card videos I have ever seen. Thank you for the amazing content Steve and team!
Damn Steve, wouldn't smoke work just as fine?
No company does this when they evaluate their cooling implementations. Just wow.
Let's not kid ourselves, there are though. Just not for trivial and mundane gamer stuff.
@@brenlouissurio2404 Fair enough. But I was referring to fan sizes of this sort. Not industrial turbines or something of that nature. The only company I imagine may do something of this sort is Noctua and their eternal R&D pace.
I find it interesting . And would love to see more ! With lots of different set ups and GPUs ! Thank you !
Great job to help us all visualise what’s actually is happening during the cooling process I appreciate your work.
Before going out and getting the high speed lens, maybe have a chat with "The Slow Mo Guys" and, like Linus, do a collaboration. They may be a good source of info for improving your new [excellent] set up!
could you use acrylic or glass as a standin for the motherboard?
more specifically, why couldnt you use acrylic or glass as a standin for the motherboard?
I would guess the refraction would be a problem
@@everythingfeline7367 that should just involve having a large enough piece of glass to cover the entire mirror, and slightly changing the distance to the camera
if that doesnt work, how about an extremely thin sheet of plastic, im talking saran wrap thin
I'd imagine a plexiglass case that is open to the mirror side, but seals reasonably to it. Then fans can be mounted front and back and at the CPU location.
Really appreciating the use of tape to mind your wires. Now that's some responsible Schlieren imaging right there. Great work, Steve et al!
I love this mix of highly professional and super DIY/homemade solutions, it's really cool!
