The formerly is what I feared when EVGA dissolved their GPU segment... These engineers should have no problems finding new work, it's just a shame that they are put in this position.

[@austinshaner]

As an engineer, I felt right at home in this video. Big companies don't typically send their engineers out for PR purposes. Because let's be honest, most engineers will bore you with the details. But from a company that keeps things pretty close to the chest, this was extremely refreshing. You can tell he's had a lot of hands on experience developing these coolers. He did a great job. Please have him back!

Personally I would have loved to have heard more on each one of these areas that he touched on. This video could easily have been two times the length and I would have still been entranced

[@adjoho1]

While I really enjoyed this segment, it's not relevant to me. I custom loop my systems, so the cooler on a GPU is relevant only for the period I power the card on to make sure it powers up. My STRIX 3080 cooler lasted about 5 minutes before I removed it and installed a water block. I wish vendors would offer a bare card for users like me.

@@adjoho1 Some vendors do sell a pre-installed waterblock versions, I think MSI and Gigabyte had one last generation. I'm running the MSI's 2080 waterblock card for example. Which was a major PITA to service, but that's a bit of a side topic.

As an Aerospace Engineer myself, this discussion was awesome. To have the computing power that Nvidia has at there fingertips to run CFD must be amazing. Most companies have to rent computing power at an incredible cost to run the types of simulations he is talking about. A company I worked for ran a similar study for a fan design we were working on for automotive and it was thousands of dollars just to rent the compute for the few days needed to run the study. This was after we tired running the simulation on our own custom CFD machine with 64 cores and the 4 A6000 an over $60,000 dollar machine at the time. Nvidia probably has 10 times the computing power just lying around.

As an Aerospace Engineer it was a very interesting video, thanks Steve and the Nvidia team for giving Malcolm the opportunity to present the inner working of the engineering aspects of your manufacturing and design processes. Especially found it interesting that he highlighted the work that has to go in to the simplests of things like flow characterisation before you can even begin to tackle other parts of what you are trying to build. Would be a dream to have access to the type of compute power he does to run CFD and FEA sims. Keep up the good work.

[@BrianPardee]

This was very neat. Thanks, Steve and crew for doing this video. It's these kind of technical videos which keep me engaged with GN compared to some other channels.

[@chrisfortune1813]

Love the engineering overload. Odd how physics is physics and many of the concepts overlap different specific disciplines. I was an oilfield researcher in my younger days and the "rarefied" concepts of porosity and permeability were voodoo science (I am talking early '80s here) and now they are discussed in tech heavy but almost mainstream media conversation. This is one of the most enjoyable videos I have watched recently an I hope it is the prelude to many more deeper dives.

[@JDelta87]

It's always good when an engineer is going over what went into making the actual product. He is naturally excited to explain the entire process and PR didn't seem to interfere at all. Great content and information everyone!

[@jhfgjtjutyiuod]

Excellent video and helps to show there is way more to designing the thermal solution than just pulling off the stock fans and zip tying noctua's on in their place like some other channels might have you believe.

[@Deltarious]

Watching videos like this always makes me wonder what NVIDIA's engineers and technical staff *really* think of their company's marketing and pricing strategies and how they feel generally about the reputation of their company. It would be wildly inappropriate to go around asking in most cases, but when you have people this intelligent contrasted against the almost predatory tactics companies sometimes use I can't help but wonder.

[@ApolloPS2]

I mean the real answer is that those "predatory" tactics help balloon their salaries so they can work amongst the best talent and develop high cost cards that still have healthy margins. This thermal engineering R&D costs serious money to obtain.

[@ligametis]

Most likely he has no idea how much everything costs. People working in finance know that way better

[@PHF28]

It's always awesome to see the amount of knowledge, engineering and manufacturing work dedicated to things that are going to be hidden. And cool to see that NVIDIA recognised the marketing potential of this. Great job, Steve.

[@christophercasale7961]

It's great to have a deep dive with someone who is both deeply knowledgeable and passionate. I learned a bunch of things about vapor chambers and fans today.

[@markholmes2419]

Really enjoyed this. I'm not an engineer and didn't fully understand everything (by a long way 🙂) but it's always delightful to listen to people speak when they are truly knowledgeable and obviously passionate about their subject. Steve's interviewing technique was also absolutley perfect; only chipping in when clarification was needed or to keep the flow and direction going. Great stuff!

[@catbertz]

water jets are bonkers. 😱 Edit: Finished watching video. Malcolm was an awesome guest and educator for a non-engineer like me. I learned a ton and really enjoyed what you put together here. You guys are REALLY upping your content game across the board this year.

[@peachierose3356]

GN never disappoints🔥

[@Wintergreen56]

The fan calculations were great to hear about. These are some of my favorite types of videos from GN. It's great to hear all the information from someone who is so enthusiastic about it.

[@jeffhampton6972]

This is so much fun to watch. You two are the types that make people want to learn math because it's actually cool.

[@Snarkbar]

Malcolm makes me want to go back and get a math PHD.

[@Watchfulfox]

Working at NASA did that for me.

[@webx135]

This is easily one of my favorite videos. I know some eyes glazed over at the math, but I would have been interested to see the formulas and charts, if that isn't private IP. I'm an engineer in the HVAC industry (albeit a software/controls engineer) so all of these details fascinate me. Especially the specifics. When you have this many variables, I'm surprised they didn't turn to AI, since this is a great optimization problem, and NVIDIA are experts in this field. One question I've always had, because my own testing seems to back this up: Wouldn't pulling be able to handle resistance better than pushing? He mentioned they were essentially treated the same. But I would think it would have more than just SP to consider. Turbulent vs laminar comes to mind. A pull is generally more laminar than a push, which is why wind tunnels pull air rather than pushing. Picture it like a "stretching" vs "squeezing" action. One of the advantages of pulling through a filter is that a filter essentially blocks air velocity and is motivated pretty much entirely by static pressure. So if you want to keep your velocity head, you would want to pull through a filter where only SP matters, and then run it through the fan to spike both the static pressure and the velocity. In a PC case, velocity helps keep air moving around passive components. That is, you can't push air into a filter and then expect it to cool your RAM 4 inches away. But I definitely found that pulling through a resistance seemed to provide a higher flow rate than pushing. I used to have my own rig setup to test this stuff. Mind you it was just a cardboard cutouts and a fog machine. I was designing a PC case and wanted to determine not just pulling vs pushing, but also optimal distance between the fan and the filter. With a bit of gap between the fan and the resistance source, flow seems to improve dramatically, as was used in the PCP&C Silencer power supplies. And it helps against stalling the blades, where the blades no longer push the air, but "spin it in place" essentially. Resources on this topic would be awesome, and I think this video was one of the best resources on this exact topic. But also, vapor chambers and heat pipes continue to blow me away. Again, I work in HVAC, so I'm used to having clear pumps and capillaries to force the fluid to be ready for a phase change. It's really cool that these happen passively through capillary action and vapor diffusion.

[@CynicalWilson]

Yes! Please more of this type of content! ♥️

[@BabyMayCry]

I love Malcolm and his passion. Very knowledgeable and enthusiastic. I hope people who worked on the GPUs like him understand that the hate NVIDIA's getting isn't because of them, but because of the poor decisions their execs are making.

[@bigshobe]

They’re making tons of money so the execs are making the right decisions

[@Cxs1a3]

You're straight up deluded if you think these engineers don't want to be promoted to executive position and end up making the exact same decisions when they're given the position.

[@LV-ii7bi]

@@Cxs1a3 Nah bro, not everyone wants to climb a ladder. Some people are actually self aware.

[@insoYT]

@@Cxs1a3 No sir, you are the deluded one here. I've worked with different engineers for past 10 years in several industries from aviation to this stuff. These engineers are not interested to climb up the ladder to find out themselves in positions where they couldn't do actual engineering work. Engineers' love for engineering is pure.

[@foxtrap614tango8]

This is just awesome. I am an engineer and this is really enjoyable.

[@Christopher_S]

GN you've once again contributed so much to learning for the community. Truthfully, I'm surprised that nVIDIA allowed an engineer to visit and share this knowledge. I am very happy to have watched this though, it's very interesting and informative. Thanks!

[@yvesmillette1721]

This is the most interesting and best video about PC components I have ever had the pleasure of watching.

[@dog_knight]

Awesome video. I understood most, but not all of it. Incredibly interesting. Will have to watch it a few more times for it to sink in. It’s great to see all the effort that goes into these products and how passionate the people behind the leather jacket are.

[@Bloodline2009]

Absolutely fascinating. The young man Malcolm clearly has a very bright future ahead of him. Thanks for sharing this highly detailed information, it's hugely interesting to watch and listen to.

[@halrichard1969]

For an Engineer he has mad verbal skills.

[@Bloodline2009]

@@halrichard1969 I was thinking the same. Also, I noticed he was wearing his wrist watch on his right arm which probably means he's left handed. Left handed people are normally good with details.

[@MadPhantom]

Before we get any reviews we got one cut in half

[@Daishi0861]

This was incredibly interesting, thank you so much for sharing this wonderful deep-dive. Couldn't have had a better person on to explain this, he was very technical while still understandable. I loved hearing about how you can actually dry out a vapor chamber and also the ways in which they combat it, I'd never considered that aspect and it seems like a pretty significant chunk of effort to get right!

[@thepowerplayer4530]

I really enjoyed this video, and this had to be probably one of my favorite GN videos, because it’s very rare (especially with nvidia) to get actual engineers to talk to the press, and they get to share all of the cool things they’ve been working so hard on. Also he was really enthusiastic about what he does and you can tell he really enjoys what he does, which just made the whole video so much fun to watch

[@SunsetJam]

I don't have much a technical mind as I once thought. Something I've learned the hard way over the last few years. So even though it's GN, I went into this vid expecting it to be dry and exhaustively boring to me. Lo and behold, these two had me entranced from the get-go. The explanations were clear, concise and still informative. And it wasn't even the cutting that kept my attention, but just the general workings of the cooler. Kudos for these two, especially from the engineer. Like others here have said, he has no shortage of passion and talent towards his specialty.

[@TechZF]

This IS a educational video!!! Thanks Steve and Malcolm.

[@pmAdministrator]

Thank you, NVIDIA, for this, and Gamers Nexus. This video is sick. Finally some real science.

[@whirledpeaz5758]

The crossover between this and the aerospace industry must be fascinating.

[@TennisGvy]

It's a lot more in depth than cooling typical for electronic boxes in the space or aero application. Aerospace has its own challenges for cooling though in things like turbine blades, hypersonic airframes, etc.

[@KZ-ko4vm]

Best video you did this year

[@TommyT1550]

This guy really understands his stuff, very very intelligent young man. He understands the technology in such a high capacity, yet is able to convey his message in a way that your everyday person can understand what he is saying. Bravo on this video, awesome content. He needs to be a repeat guest, especially after the full launch.

[@HybridMarco]

Pure passion, taking such complex ideas and showcasing their thought process behind it was incredible. Making engineering cool is an understatement

[@Gersberms]

This is pretty much the best content of its kind. As geeky as it gets, but still show & tell with plenty to look at.

[@mikee3437]

I really enjoy videos like this where engineers or architects go into a deep dive on how their product works. I really enjoy how Intel does this on their channels and I also really enjoyed this one by Nvidia. Excited to see more like this in the future. Hopefully we get some AMD videos as well.

[@infra1]

Forget the company for a moment, look at the passion and smarts of this young kid. The world needs more inspiration of this sort! Great vid Steve et al.

[@Lambda.Function]

Big props to nvidia for being open with their engineering for the public. One of the best decisions nvidia has ever made. I would love to hear from someone on the team why the cooler is so over-built for the 4090 and why the card ships so hot by default. It would still crush the market at 70% power target but use 100W less and need much less cooling, but have that room for overclocking.

[@DoNotFitInACivic]

That, likely, was a C suite decision. As it seems that NVIDIA plans to drive the AIBs out of the market, and having that much OC benefits on the table for those "little" companies to show off would hinder that.

[@flyingrichie]

Thanks Steve!

[@snowhawk4049]

Thanks to Nvidia and GN for making this possible, great and unexpected content.

[@OzTechGuy]

For a video about cooling.... my brain just melted :)

[@pauldehayes1898]

As a lab person who processed thermal spray coatings through epoxy mounts, that's a nice polish from what I can see. I don't think you'd use a diamond-based polishing paste for this application, but would be interesting to know what is used for softer materials. Used to polishing metals like 300 and 400-series SS, Inconel, and Tungsten Carbide; with nickel-based alloys as well as ceramic coating types bonded to the aforementioned metals. Love this kind of stuff!

[@jesusraya4484]

I absolutely love these kind of videos into the engineering that goes into our hobby products. I'm studying to become an engineer myself and I always wondered how they narrowed down their decision towards a specific design, or design choice. Videos like these really help paint a picture to better understand the engineer process involved.

[@Watchfulfox]

Hobby? For some of us the computer is our livelihood and what pays or bills.
