You need to get an EU store / HQ / Warehouse , so people are paying 100$ for a 50$ product as an example, import fees from American stores are huge. And before anyone comments, BUT murica, yes you're a small country compared to all of Europe where we match Murica by 2½ times the population and have way more spending capital, so any american company that wants to super thrive needs to have a EU warehouse.
These are awesome! Makes me glad to help out on Patreon and buying shirts! I've learned a lot and I wish as a recent mechanical engineering grad whos into thermal related stuff, that I could get a job as cool as Malcolm
I really like the "find nerd, get them to infodump" format. Especially helpful that you've found people who can really articulate what's going on at a level us mere plebs can understand.
I think you made a great observation- like they said in the preamble, he did not dumb it down, but with technical discussions there are ways to explain complex topics more eloquently/easy to digest than others, and GN has a really good eye for experts who know how to tow that line.
@@PanderingSlats It's considered a demonstration of how well someone understands the topic - the better you understand a thing, the easier it is to explain to someone with no understanding. Malcolm does this very, very well.
@@grievesy83 the only exception is monads, as soon as you understand them you loose all ability to explain them to anybody else, to paraphrase douglas crockford. - There are two types of ways people usually try to explain it, something along the lines of saying its like a burrito (which is entirely useless beyond saying it "wraps" something), or the classic "a monad is a monoid in the category of endofunctors" (which is only useful if you know what each of those words means, at which point you already know what a monad is. imho the classic "a tensor is something that transforms like a tensor" is more helpful than that for a person unfamiliar with the topic)
This isn't his work though. He said it at the end, I really enjoy talking about this stuff. I would expect his actual work to be really quite tedious and boring. I'm sure he doesn't mind that too much, because it's within a field he is interested in and passionate about engineering, whilst also having times that are great. Am I being pedantic, sure, but I think the distinction is important. He has the makings of a great university professor though, passionate when speaking about stuff, probably enjoys teaching and has potential to be a great communicator.

Man, Gamers Nexus is quite literally The Greatest Tech Channel That's Ever Lived. I can't imagine the effort involved in these deep-dives, and I truly appreciate what Steve and crew do for this community. Seriously admirable.
You know you're talking to the right guy, when they are ear-to-ear grinning the entire time with excitement. Shout out to Malcolm, dude. I understand the individual references he's making when explaining things, but I know that what he's saying has 3-8 deeper layers internally. And that just makes me enjoy this entire thing even more. Malcolm is "That" dude.
I have been very suprised by how much the engineers from several of the big companies have been able to go on camera lately! It really is great to see...@@GamersNexus
@@TheChzoronzon I think he did a pretty good job considering the amount of time he had, but I may feel that way because I already had some cursory knowledge on the topic...
So interesting. If you roll down only one window in a car, you can hear the modulation caused from the backflow of pressure, which can be painful when driving at high speeds. If you roll down another window, it creates a pass through, which reduces the backflow of pressure and the modulation.
@@HanSolo__making things cheaper without loss of quality IS making things better. Effectively that means you can get better cards at your price point.
This guy is clearly extremely knowledgeable in his field and appears to be quite young. Hopefully nvidia realizes how valuable someone like this is to have on their team. Good job Malcolm.
I love that the industry is becoming more open to the media like this. It certainly makes me more inclined to buy products from companies that allow content like this to be made.
As an audiophile and someone who obsesses over finding the perfect thermal solutions for every device I’ve put my hands on, this was truly one of if not the most fascinating and entertaining video I’ve seen in a long time. That guys an INCREDIBLE speaker and teacher. I was hooked in the entire time. All of it was so informative and easy to understand. This guy broke down everything perfectly! Thanks for covering this and sharing it. You guys are absolute legends ❤
Good that Gamers Nexus is becoming so prominent. Most techtubers are as deep as a puddle, so seeing you guys succeed makes me happy. Btw: the special technician is adorable. Does it hate coil whine too?
Most people don't know, coil whine is actually the screaming of poor souls straight out of the pits of hell, which Nvidia swallowed with its 4000 and 3000 series of overpriced trashscam graphics cards
got recommended this and i love learning from videos such as these :) the actual psycho-acoustics for human perception of sound is so interesting to hear in situations such as these where there needs to be optimizations for everything
I just know that this interview is a major highlight for Malcolm. Look at how happy he is to talk about this stuff that he is entrenched in, and clearly passionate about. I think it was as good for him as it was for us 😂
I may not like Nvidia as a company, but the actual engineers behind it like Malcom and the rest of the team who actually DO the work the CEOs take credit for are awesome, I always love to hear from them instead of PR and shit
Ah yeah, i fondly remember all them CEOs getting on stage, holding up the company's product(s) and proudly claim "I did this! I am the genius who did this!" Man, do i love UA-cam's comment section, it's never lacking in infantile BS potshots, lmao...
I love this sort of engineering technical deep dive, and Malcolm's explanations of it all are wonderful. If I could like this video a thousand times, I would. Also really love the parallels with aircraft wings and stall characteristics, that's definitely a part of this that I'm personally very familiar with.
Damn Malcolm is a smart cookie! It's refreshing to see someone so young being passionate about something as complex as this. Good for him on achieving such a good career path and working for such a prominent company, I'm sure it wasn't easy, but well worth it in the long run! We welcome Malcolm back anytime!
Malcolm! Great to see you on GN again! The information you provide, combined with your passion for your work, is a real joy to watch. 💚 (Also - I love your smile!) This was really interesting to me - especially the stuff about fan blades. It's awesome to learn how my video card is cooled, and why it is so quiet. But to be honest, I'm gonna have to watch that Stall Region segment again, because it kinda went over my head. Haha... And to GN: I love this type of content! More more more, please! :-D You manage to get really awesome guests. Malcom, TAP, Bill, and Amit are starting too feel like members of the GN family at this point.

Dude, your pick of engineers from all 3 "teams/camps" was stunning, loved that guy and his enthusiasm and subsequently deep knowledge, as well as AMD guys, I pretty much felt at home with those videos, and even I'm more of a hardware guy, especially OC/cooling, I also really loved the "Intel dude" and his contribution about arc arch and hw/driver/pipelining topics, love that actual usefull knowledge and not just stats rambling so that punchy title can be used and video heavily monetized...

I'm really impressed by the range of topics this guy can talk about in detail off the top of his head! So many areas of engineering involved in this discussion.
Thank you for this interview. It is awesome to hear two excited engineers talking about complex stuff and somehow make it understandable and very interesting!
This is so incredibly interesting and informative! The last video you did actually changed what type of engineering I am looking to go into. I could watch Malcolm talk for hours about this stuff. These kinds of videos makes me glad to have bought the GN coasters when they came out.
I work in an ENT office (and also have a bachelor's degree in psychology from a different time in my life) and deal with some of these topics on a routine basis. Can confirm much of what was said by the engineer, and i love the people (including malcom) and the content of this video! Great work as always GN!
Excellent video. Really loved hearing everything in so much detail without being dumbed down. It's a pleasure to watch when your guest is as knowledgeable as Malcolm. I hope to see more of this type of content regularly. Maybe with a RAM manufacturer like Corsair, Gskill etc and what they do with the memory chips after and before assembly.
Oh yeah, tech deep dives with actual engineering. So glad GN has found an unfilled niche of content to blow wide open. First 1/3 of the video was basically fluid dynamics and I am totally here for it!
Really enjoyed this discussion. Made me understand the intricacies of fans a lot more. I like these videos that are on a level that don’t lose too much information by beeing simplified.
This is what truly sets GN apart from any other Tech Channel... this degree of access to highly skilled active members of the industry, getting first hand expert knowledge and sharing it with all of us, just damn amazing! Now if only GN would make the switch to Nebula so we'd also get fully uncensored vids without any need to worry about monetization.... that'd make the experience perfect.
Everything else about the ear was very insightful and approximately correct. However around 32:22 the inner ear doesn't act as an amplifier. There is only one active device in the ear and it's a muscle in the middle ear to act as an automatic gain control/mute for when the system is exposed to excessive sound pressure levels. It has the ability to add attenuation. - Signed Evan Foss engineer with +15 years in hearing research & electronics design.
@@martinkrauser4029 no because you can't. The walls are not something you can separate like that. However I have helped people section them in a machine called a microtome. I was also the designer of an electronics package that let scientists measure sound pressure levels in the cochlea using fiber optics. The design for this is visible on GitHub if you doubt me.
The primary function of the middle ear is to match the impedance from air to water. In fish there is no middle ear, their hair cells are exposed in a structure called the latteral line on the sides of the animals body.
The inner ear certainly does act as an amplifier, and an exceptionally good one at that. The active energy feedback from the outer hair cells in the cochlea is what makes mammalian hearing so sensitive (down to displacements of 0.3 nm) and frequency selective (0.3% of an octave) across a huge dynamic range (120 dB). We still don't fully understand the mechanics of how a salty blob of various gelatinous membranes is as effective as it is, but the "cochlear amplifier" is critical. For anyone interested in learning more search for "The remarkable cochlear amplifier" in Google scholar for a good starting point.
0:30 I asked for a freaking shark with a lazer strapped to its head... and this is what you brought me? Is the animal vicious at least? Is his owner evil?
Engineers getting to talk about the engineering which they are passionate about is a great reminder to us that there are a LOT more folks involved in the creation of a product than just the "business facade" we're so often presented with
"Does it hurt you when someone manually adjusts their fan RPM?" @26:53 HAHAHA!! I loved that question Steve! It made me laugh too! Given all the years of education, engineered design, lab tests, iterations on product, and the goal to provide an optimal experience. Then, the end user just wipes their butt with that and goes full throttle because I'm uber uber leet and I need the fan noise picked up on my mic to tell everyone that I got mad skillz!
As far as his response goes, he mentioned the stock curve being the best for the user listening experience. But, if sound isn't a factor for you (let's say if you have your computer in a different room than where you game) then you can just crank the fans up to max. Yes, you'd use slightly more power and probably decrease your fans' life span but you'd get better cooling.
Fascinating talk. As an Aerospace engineer how also focuses on fan and cooling product design it was a very interesting conversation and Malcom explained everything very well.
Awesome interview! I'd love to get Jakob and Malcolm together at some point to talk shop. Thanks for all the b-roll Vitalii, these opportunities don't come around often so it's great to see as much as possible. I am slightly disappointed we didn't actually get to see any "coil whine" testing.
I'd love to get a patreon video of what was left out of the video. I'd imagine you spent hours talking with Malcolm and this is a really interesting topic that i would love to learn more about. Once again, an amazing engineering discussion video. Great job GN team!
One thing that I have always wondered. The automobile industry figured this out decades ago. Tires have grooves in them, and they could easily hum at a certain frequency. However, somebody figured out that you can alter the spacing of the grooves so that there is not one dominant frequency. The same thing for fans. Check out a really old car with a fan blade attached directly to the engine (no electric motor). The blades are not symmetrical. It seems that if you arrange the fan blades so that they didn't have perfect radial symmetry, you could reduce the frequency spike.
Well yes, a friend at school did a project for his physics exam that used the reflected energy of a non visible laser on a window to pick up sound, it was very impressive and that was 1988.
Malcolm is really good with his public speaking or presentations, whatever we want to call it. He reminds me alot of john carmack in the way I could listen to carmack speak for an hour and 70% of what he said would go over my head but still enjoyed the talk, same here with Malcolm and the previous cooler one aswell. Good stuff, thanks GN and Malcolm/nvidia.
morning coffee and getting the optimal operation point of a fan explained, with the maximum coefficient of lift after stall, is my personal week highlight. thanks for that
Thank you for sharing such an interesting and detailed video. Looking forward to more in the future! There’s one small wording mistake, which I mention only because it opens an opportunity to expand on the importance of psychophysics. At around 32:30 Malcolm mentions that the cochlea “perceives” different frequencies. The cochlear is a sensory organ and technically senses sound, whereas the brain perceives sound. The key thing is that what the brain consciously perceives is related to, but not the same thing as, the physical properties of the world. Specifically for hearing, frequency is a physical property (and sensed by the inner hair cells of the cochlea), whereas pitch does not physically exist - it is created in your brain! Steve is spot on when he says “it’s not just the levels, it’s the perception of the levels”. A similar thing happens with all senses and Psychophysics is essential for understanding why subjective experiences, both between contexts and people, can vary so wildly.
Fascinating educational discussion - thanks for keeping science and intelligence relevant and accessible. So inspiring to see Malcolm/Steve's passion for their work.
I assume these videos get relatively few views compared to reviews and the like, so just wanted to say as a current "engineer" in school I really appreciate these types of videos. Hell, even if I wasn't going into engineering I'd still love these deep dives.
30:30 It might interest you to know that that modulation you mentioned, is what (we) organists use to tune an organ to the reference principal pipe (which are tuned more rarely, exclusively by pros; the organist takes care of tuning the other pipes around 4-8 times a year): By drawing two stops, a principal and for example a flute or trumpet, we force the resonance and then tune our way out of modulation until they sound as one.

You can tell that Malcolm knows his shit and loves his job. Really love seeing passionate people explain stuff that's way, way over my head ;D
I liked Steve's question about how the two different types of flow would look like!
I work in an ENT office (and also have a bachelor's degree in psychology from a different time in my life) and deal with some of these topics on a routine basis. Can confirm much of what was said by the engineer, and i love the people (including malcom) and the content of this video! Great work as always GN!
I appreciate how nice the audio is in this video, at least in the chamber. It's like podcast status.
Excellent video. Really loved hearing everything in so much detail without being dumbed down. It's a pleasure to watch when your guest is as knowledgeable as Malcolm.
I hope to see more of this type of content regularly.
Maybe with a RAM manufacturer like Corsair, Gskill etc and what they do with the memory chips after and before assembly.
This seems like a good place to use "venjent - laser grave" as a backing track
Oh yeah, tech deep dives with actual engineering. So glad GN has found an unfilled niche of content to blow wide open.
First 1/3 of the video was basically fluid dynamics and I am totally here for it!
Really enjoyed this discussion. Made me understand the intricacies of fans a lot more. I like these videos that are on a level that don’t lose too much information by beeing simplified.
Losing*
@@Wootguy238 You are correct! :D Changing the eyesore.
i love it when someone talks about their profession with such passion. you dont see that anymore
This lesson is going to greatly help participants of the Fan Showdown.
This is what truly sets GN apart from any other Tech Channel... this degree of access to highly skilled active members of the industry, getting first hand expert knowledge and sharing it with all of us, just damn amazing!
Now if only GN would make the switch to Nebula so we'd also get fully uncensored vids without any need to worry about monetization.... that'd make the experience perfect.
Everything else about the ear was very insightful and approximately correct. However around 32:22 the inner ear doesn't act as an amplifier. There is only one active device in the ear and it's a muscle in the middle ear to act as an automatic gain control/mute for when the system is exposed to excessive sound pressure levels. It has the ability to add attenuation. - Signed Evan Foss engineer with +15 years in hearing research & electronics design.
ok hot shot but tell us. have you ever stretched out a cochlea
@@martinkrauser4029 no because you can't. The walls are not something you can separate like that. However I have helped people section them in a machine called a microtome. I was also the designer of an electronics package that let scientists measure sound pressure levels in the cochlea using fiber optics. The design for this is visible on GitHub if you doubt me.
The primary function of the middle ear is to match the impedance from air to water. In fish there is no middle ear, their hair cells are exposed in a structure called the latteral line on the sides of the animals body.
The inner ear certainly does act as an amplifier, and an exceptionally good one at that. The active energy feedback from the outer hair cells in the cochlea is what makes mammalian hearing so sensitive (down to displacements of 0.3 nm) and frequency selective (0.3% of an octave) across a huge dynamic range (120 dB).
We still don't fully understand the mechanics of how a salty blob of various gelatinous membranes is as effective as it is, but the "cochlear amplifier" is critical. For anyone interested in learning more search for "The remarkable cochlear amplifier" in Google scholar for a good starting point.
Love Malcom's enthusiasm, you can tell he loves his job and is good at it.
As a mechanical engineer I love these videos. More whiteboard please, it just feels like home. 🥰
Love this one. I'm an aerospace engineer, was great to hear him get really into the nitty-gritty with the fans.
0:30
I asked for a freaking shark with a lazer strapped to its head... and this is what you brought me?
Is the animal vicious at least? Is his owner evil?
Engineers getting to talk about the engineering which they are passionate about is a great reminder to us that there are a LOT more folks involved in the creation of a product than just the "business facade" we're so often presented with
"Does it hurt you when someone manually adjusts their fan RPM?" @26:53
HAHAHA!! I loved that question Steve! It made me laugh too!
Given all the years of education, engineered design, lab tests, iterations on product, and the goal to provide an optimal experience. Then, the end user just wipes their butt with that and goes full throttle because I'm uber uber leet and I need the fan noise picked up on my mic to tell everyone that I got mad skillz!
As far as his response goes, he mentioned the stock curve being the best for the user listening experience. But, if sound isn't a factor for you (let's say if you have your computer in a different room than where you game) then you can just crank the fans up to max. Yes, you'd use slightly more power and probably decrease your fans' life span but you'd get better cooling.
What are you on about?
Fascinating talk. As an Aerospace engineer how also focuses on fan and cooling product design it was a very interesting conversation and Malcom explained everything very well.
Malcolm is wicked smart for such a young man. Amazing.
Videos like this are why I subscribe to this channel.
I love seeing and hearing the tech guy explaining their crafts. This dude and the AMD overclock guy are truly at the peak of their game.
So refreshing to hear someone who knows what he/she is talking about and is excited about it. 👍
Awesome interview! I'd love to get Jakob and Malcolm together at some point to talk shop. Thanks for all the b-roll Vitalii, these opportunities don't come around often so it's great to see as much as possible.
I am slightly disappointed we didn't actually get to see any "coil whine" testing.
I'd love to get a patreon video of what was left out of the video. I'd imagine you spent hours talking with Malcolm and this is a really interesting topic that i would love to learn more about. Once again, an amazing engineering discussion video. Great job GN team!
One thing that I have always wondered. The automobile industry figured this out decades ago. Tires have grooves in them, and they could easily hum at a certain frequency. However, somebody figured out that you can alter the spacing of the grooves so that there is not one dominant frequency. The same thing for fans. Check out a really old car with a fan blade attached directly to the engine (no electric motor). The blades are not symmetrical. It seems that if you arrange the fan blades so that they didn't have perfect radial symmetry, you could reduce the frequency spike.
Coil whine is exactly what I've been wishing ya'll would include when doing reviews on GPUs, PSUs, and mobos
You had me at diagnostics and kept me with theory plots (and laser interferometry).
As an engineering student in university, I absolutely love these, thank you GN.
Very cool you got to pick his brain about the testing room. good job Malcolm
Well yes, a friend at school did a project for his physics exam that used the reflected energy of a non visible laser on a window to pick up sound, it was very impressive and that was 1988.
Malcolm is really good with his public speaking or presentations, whatever we want to call it. He reminds me alot of john carmack in the way I could listen to carmack speak for an hour and 70% of what he said would go over my head but still enjoyed the talk, same here with Malcolm and the previous cooler one aswell.
Good stuff, thanks GN and Malcolm/nvidia.
this was the quickest 40mins I've experienced in a while 😁 thanks for the deep-dive, Steve!
seeing this model of scanning laser interferometer brings back memories of my master thesis where I worked with that exact instrument.
morning coffee and getting the optimal operation point of a fan explained, with the maximum coefficient of lift after stall, is my personal week highlight. thanks for that
I'm so nerding out at this video, thanks GN & Nvidia for dropping it! Big like.
Malcolm's knowledge and passion is inspiring to say the least.
Thank you for sharing such an interesting and detailed video. Looking forward to more in the future!
There’s one small wording mistake, which I mention only because it opens an opportunity to expand on the importance of psychophysics. At around 32:30 Malcolm mentions that the cochlea “perceives” different frequencies. The cochlear is a sensory organ and technically senses sound, whereas the brain perceives sound. The key thing is that what the brain consciously perceives is related to, but not the same thing as, the physical properties of the world. Specifically for hearing, frequency is a physical property (and sensed by the inner hair cells of the cochlea), whereas pitch does not physically exist - it is created in your brain! Steve is spot on when he says “it’s not just the levels, it’s the perception of the levels”. A similar thing happens with all senses and Psychophysics is essential for understanding why subjective experiences, both between contexts and people, can vary so wildly.
Absolute gold mine for engineering education. Kuddos team.
Graphs and math! I've been obsessed with fan design for years. Really cool to have an expert describe the nuances.
Fascinating educational discussion - thanks for keeping science and intelligence relevant and accessible. So inspiring to see Malcolm/Steve's passion for their work.
I assume these videos get relatively few views compared to reviews and the like, so just wanted to say as a current "engineer" in school I really appreciate these types of videos.
Hell, even if I wasn't going into engineering I'd still love these deep dives.
30:30 It might interest you to know that that modulation you mentioned, is what (we) organists use to tune an organ to the reference principal pipe (which are tuned more rarely, exclusively by pros; the organist takes care of tuning the other pipes around 4-8 times a year): By drawing two stops, a principal and for example a flute or trumpet, we force the resonance and then tune our way out of modulation until they sound as one.
Malcolm is amazing. That is all -thanks for the upload!
Can't believe this is free to watch. what a time to be alive.
that dude is 20 years old with 50 years of experience...glad to see him again on the channel
