PC Fan Engineering, Noise, & GPU Coil Whine | Engineering Discussion ft. NVIDIA
174,444
Published 2024-04-09
In this next addition to our engineering deep-dive series, we talk with Malcolm Gutenburg, a thermal engineer at NVIDIA (and formerly Intel). This video goes deep with acoustics engineering as it relates to thermal design, so we talk about finding and identifying coil whine with lasers, fan blade design and engineering, critical bands and one-third octave bands for data presentation, and tone-to-noise prominence ratio. The discussion also gets into psychoacoustics and the structure of the inner ear.

Our next installment in our engineering interview series we've been doing this year! These have been crazy educational - can't wait to do more! I have no idea how this video will perform since it's tough to title with all the topics, but it's such a great technical discussion that we're hoping people see it. If this interests you, you'd definitely like our engineering interview with Noctua previously! https://www.youtube.com/watch?v=82LZkglNiQ0 We self-fund all our travel for these events to retain full control over the reporting process! To help support our next engineering interviews, grab a GN Modmat, Soldering Mat, or shirt here! store.gamersnexus.net/ Or watch our video cutting the RTX 4090 cooler in half previously, also ft. Malcolm! https://www.youtube.com/watch?v=g4lHgSMBf80

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.
-
We appreciate the deep dives in engineering education. Even Greg.
-
These deep technical discussions are the best type of content.
-
He seems really passionate about his work which is always nice to see.
-
i appreciate the "not dumbing it down" more that you know. thanks.
-
Damn the thermal engineer is so good on camera
-
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.

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.
-
Steve once again educating us through the power of science and friendship.
-
Malcolm is back... with lazers & puppies 😊 im in...

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.

more videos/series like this PLEASE

He sounds very knowledgeable with zero arrogance. He knows how to speak.
-
Thank you for raising the tone, quality and audience respect on YouTube when so many channels head in the opposite direction.
-
My younger self wouldn't have imagined my future self being so interested in a 38-minute video about fan noise, I guess I'm officially a nerd now!
-
My dude Malcolm. Good to see him back.
-
Malcolm’s back, not trying to discount the other peeps, but as a SDE I it’s great to see a more rank-and-file engineer instead of the principals
-
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.
-
I love when the sound engineer says "you can SEE, it's a lot less echo in here."
