@@broklond To represent stock he could just use the after-market cooler with stock noctua fans,. The point is to have an interface to mount the custom fans with no other variables, the GPU is only a heat source at this point.
Run the fans from external power supply, so the GPU can't mess with RPMs and make 2 categories: 1. Test noise and temps at 100% (best for max performance) 2. Test temps at given noise levels (best for casual use) Why? Because the reasons for someone to use custom fans are: - improve temps (performance) at all costs - cool looks (with still acceptable noise)
Yeah but he said the rpms werent reporting. Either the pin broke or the output transistor burned our. Though its weird because all these fan are open collector on the tachometer so kts really hard to burn that transistor but not the coild drivers.....i bet he broke some cable or something.
@@laharl2k another similar reason may be that the fan blades are too heavy and require a small capacitance to start . With the added weight the motor pulls too much amperage by itself and trips over current protections. Adding an appropriate micro-ferret capacitor may take the start load off the motor.

Ooh! I bet I know what's happening! I had to diagnose these problems last year with my 2080ti. If the fans are ramping up to 100% without reporting their rpm there are a couple of culprits I can think of off the top of my head. I would make sure that the pci-e is set as flush as possible. If any of the pins aren't completely flush it can fail to report, causing the card bios to force 100% speed as a failsafe preventing thermal throttling. The other culprit can be bad thermal paste application, or drying out of paste, or some other temperature probe inside the card not being properly cooled. Sometimes these cards have a temperature probe snuck somewhere on the card, and it can either malfunction, or may not be getting adequate cooling. So I would check thermal paste application, make sure the pci-e is making connection with all the pins before you go for another card. Worst case scenario you could flash the bios and see if that fixes anything.
@@Spartanwarlord basically the way fans that have speed control built in (4 cables) are made and how the card reads the speed, are made in a way that is really hard for them to fail just because he added a heavier fan to the motor. Its even harder for them to break exactly in the part that generates the "speed" signal. So the conclusion was that his card not reading the fan's rpms was most likely not due to the fans overheating but a broken cable or pin or a bad contact somewhere when he rebuilt it.
Honestly....gpu fan designs is just in time for the industry needing better cooling! This is going to be absolutely wicked series. Love that you do these showdowns man. Cooling is so important and invitation is key.

Get/print a ball/plug that fits in the tube with a small amount of clearance. Have distance marks on the tube. Have the fan set up under the tube blowing up into it. See which fan design can push the ball/plug higher. I suggest a fixed rpm. Keep up the great content. I appreciate it.
I did a similar experiment, that is break off the blades of a bog standard case fan, sand it and then attach the printed noctua blades and hub (adjusted to fit over the bog standard hub). Worked alright, bit wobbly, but good enough for government work! The hub did get a bit warm, so it was working harder that it was designed to. But I reckon Mr Hardware will hone this art to a fine tee, looking forward to this series!

@@wolfieplays1423 yeaaa that's the one. At that point it doesn't really feel like a regular GPU though haha. So not sure how much it would detract from the "GPU charm" I'll call it

Linus noctua fan has bad blades. They are "blow back" many of air volume bacause space between fan and fan case is big. I have one on my back wall of pc case. The yelloy fan in this video don't do this. Maybe thats why temperature lower.
it's their default feature. ngl, my XFX RX 580 runs cooler than that 1080Ti with stock fans... idle temp at 22°C (fan at 40%, since idle is 38%), and at max it will reach 55-57°C depending on the load.
Your welcome for the native solidworks part xD. Thank you so much for continuing to experiment with my bladeless design! I love it! I have all the way up to like version 5. Please reach out if you want to give any of them a shot!
Ok. (being real I paused this 3:15 in) You could measure and find a way to mount 2x that noctua fan onto the card, make a mounting rig for it. THEN use 2x blades to cool it. I know it might sound sound off, but when using SFF (Small form factor) cases such as the NFC Skyreach Mini (and S4 mini) there are some that do this to de-shroud GPUS and just add Noctua fans to them for optimal cooling.
Big fan of the normal fan showdown series you have been doing and to see you take that and apply it to GPU's is quite exciting. Can't wait to see what happens in the next video :)
@Major Hardware Fan hub motors that are small like that actually need cooling so the core windings don't overheat and burn out. Desktop fans have the same issue, if you've ran fans for a while then felt the back where the label is or the hub itself it's warm, the less airflow there is the hotter it will be and since the rear of those fans are touching a burning hot heatsink it's possible they overheated and they malfunctioned. Based on the RPMs you're getting, it's likely the control circuit (on the fans, under the hub) overheated and failed catastrophically. Might be able to discover more with a disassembly of the hub itself. Board might be discolored on the back of the fan under the label and under the plastic.
Love the idea! A lot of stock GPU fans suck, especially noise wise. The 3D printing time lapse was great, by the way. More of those would be appreciated.
Remove the top cover, print a new one that fits 2x120mm standard fans, put the Noctua fans and you are done. Put the fan connectors on 12V directly (or whatever V you decide) and you are ready. Plus you now have a bunch of fan designs available. I am quite sure you will be have more and more troubles with the stock fan motors and power supply if you stick to it.
My Gainward Phantom GTX 980 had these fans that you could pop out the side of the shroud without disconnecting any cables so you could clean them. Yes they were puny 90mm (I think) things but for testing designs that might not be the worst thing.
I can't remember if this was mentioned before, but the smoke test might be adding another variable depending on the type of smoke liquid used. Some of them do leave a greasy residue which can't really be blown off with a compressor or canned air like you can with dust, and will probably reduce the heat fins' ability to transmit heat into the air being passed through. If this is a non-issue with the type of smoke liquid used then nevermind me, but if it is, it would probably give later contestants a bit of a disadvantage.
Why not try making an outer support ring on the new fan design. might help prevent centrifugal destabilization & could prevent the fan from blowing apart if that is your concern.
You can bypass the fan controller on the card and power the fans with your bench power supply, that way you can get CC or CA measurements per fan at a known volt/amps draw.
Depending on what is wrong, heating your GPU in an oven can melt and resolder GPU board connections potentially reviving a dead board. Not my first recommendation on a malfunctioning GPU.
@@unoriginalproductions2591 For many old GPUs it seems like putting the GPU in the oven "repairs" it when the GPU itself is bad while it actually just extends its life for a few weeks. I’d recommend making sure reflowing is actually needed before attempting it.
Funny thing is; "Baking" a GPU should, for all intents and purposes, *not* work. An oven just doesn't get hot enough to actually reflow solder. Not to mention it might melt something important on the board. And yet... It has worked for people, again and again.
@@The_Keeper really depends on the solder used, some can melt at a very low temp, easily achieved with an oven but reflowing is never the answer to every dead board
I had 2 ideas for fan prototypes, but I'm not really setup to design them. So if you like the idea please design one and send it in. 1. Balanced Asymmetry: The idea is based on tires, which use irregular spacing between the nobs, so there is not a single frequently, but many different, so it is nicer to listen to. The idea therefore is to use many blades (~9-11) and distribute them unevenly around the center. To counteract the offset center of mass, my idea was to have different width blades. 2. Idea is inspired by the very large spiral from one of the older videos. My idea was to make the fan wider than the usual ones and to have a layer on the outside, which prevents air from blowing out. The idea is, that it has a bigger inlet and can guide the air to the cooler. Also the angle of the blades maybe should be shallow, to increase the pressure.
I think the best idea would be to take a Arctic Accelero Xtreme IV an put some Noctua Fans on it to get a reliable test Setup that you can use on many different GPUs.
GPU with a Noctua Fan (I mentioned it in community already as well as multiple previous videos): Just go for Morpheus aftermarket cooler. Besides of looking cool and having awesome performance, you can also attach whatever fans you want.
If you can actually get your hands on one, ASUS has collaborated with Noctua on an RTX 3070 and RTX 3080. So, perhaps you can finally revive this idea now.
There are 3rd party coolers for GPUs that allow you to fit 120mm fans on them, would be easy to attach noctuas to them to make a consistent test bench, problem is that it takes away the curiosity of fixing stock coolers with different fans.
I have a Raijintek Morpheus II on my Vega 64. It's an aftermarket aircooler like Arctic also make and it allows you to run aftermarket fans on your GPU. Mine has 2 nice Noiseblocker 120mm fans on it and it's really good. It runs at about 50-60° depending on ambient temperature and load, which is a significant improvement over the stock AMD cooler (obviously).
User a riser cable so you can run the gpu far away from the test bench to avoid accidents inside the case, and so it would have enough headroom for crazy large fan designs
When you put the reflective tape on, You should put it on the motor so it minimizes the imbalance created. Yes tape is light, but the whole thing itself is pretty light and the further you have it from the center the more of an effect the weight has. That's why that fan is bouncing when it wasn't bouncing before
There's a high chance you tripped a polymer fuse due to too high current required to run the heavier bladeless fan. Polymer fuses heat up and cut power, once they cool off they allow current to pass again.
Definitely a great idea! Best option to me would be slapping the motor assembly from the Noctua onto the GPU. Doesn't seem too hard either. Would just need to make some sort of bracket. Might already be one out there
Maybe consider an external fan controller like the corsair commander? or use a uC like an Arduino for some easy PWM? Anyway, I'm just so excited to see this series continue. Fabulous creativity and interaction with your audience. This is my favorite channel on youtube at the moment.
Noctua does sell fans in an assortment of sizes. You could try using the hubs from a smaller size. Aftermarket coolers also exist so that’s another option.
I’m no good with modeling, but I’d love to see what would happen if you combined the Bladeless design with a traditional fan. You could adjust the angle of attack on the connecting splines so they function like traditional blades to be the primary air mover, but also keep the dome design from the Bladeless to capture the current lost to centrifugal force.
Transplanting the noctua motors would be an interesting standalone video, but i think best course of action is an aftermarket cooler that already has 120mm fans (maybe transplant the noctua motors anyway, so it's just one file to keep track of and previous fans can be tested more easily)
Airflow and airflow against pressure are 2 very different things. You wouldn't think that a radiator specifically designed to have air flowing thru it would restrict airflow all that much, but it really doesn't take much at all to cause major differences.
Maybe a powercolor GPU? Seems like they usually have some of the most robust cooling solutions. I hope you're able to iron out all the little bugs so we can have a full on GPU fan showdown. I would suggest getting some kind of riser cable and card mount. this way you can isolate sound from CPU/GPU better when doing noise tests, and other fun filming stuff like dumping the smoke directly into the cooler.
i actually have a 120mm fan which seems to have a built in controller with some interesting routines programmed into it , for when it detects scenarios like the fan isnt spinning due to an obstruction; it would cut power and restart the fan 4 times before giving up perhaps these GPU fans have similar logic and hardware which detects when e.g. a blade has broken off, or if a motor coil is burning up? maybe the reasoning for that is the GPU's own thermal shutdown is a lot more controlled and harmless than the electrical, mechanical or even fire risks posed by forcing a faulty fan to continue running
11:39 When the fan motors started spinning and the MGS alert sound went off. I got a text at the same time and that's my text alert sound as well. DOUBLE SHOCKED!
Noctua fans on the gpu would work best for sure, but I think that the factor that would make a gpu fan showdown interesting is the high rpm nature of gpu fans. You could maybe limit fan height/mass to not overload the motors and create some design restraints to differentiate it from the normal one. Oh and maybe the fans might lose friction on the plastic hub and the hub would spin inside a stationary fan. That could be a potential issue to resolve with this..
You could always looks at that third party Raijintek cooler (the morpheus). It’s a pain in the ass to install (and I do NOT recommend using their included thermal adhesive because it doesn’t actually hold any of the included heatsinks in place) but it would allow you to use two noctua fans instead of needing to use whatever the included motors are on the GPU.
I like the 30 blade design I was a jet engine mechanic on b 52 h aircraft. The problem with it is that its for compressing air molecules in stages. And on the tf33 there is 16 stages but only 15 actual stages the first 4 is fans. The first 2 fans is driven by the last 2 turban stages by a shift that runs though the center on the engine supported by precision bearings. Would it be possible to make a fan blade that is intake and transitions to turban to drive itself to a degree to get higher rpms The turban side should be 20 to 40 % less coverage of intake to allow intake air to bypass
Clearly you just need to sacrefice 2 noctua fans and DIY them onto the card ;)

If you're going to take a Noctua for the GPU, use the slimmer NF-A12x15 model for it. It's much closer to the typical thickness of GPU fans.

@@ericbaker8807 he might be able to print a custom gpu face and integrate the noctua fan motors to it I have a picture in my head on how it would look
@@wolfieplays1423 maybe. I re-watched the LTT video and the heatskinks that go on the vram modules and stuff kept falling off... So probably not the best kit for an already flaky 1080 hahaha. Other than that the results were pretty sweet
Linus noctua fan has bad blades. They are "blow back" many of air volume bacause space between fan and fan case is big. I have one on my back wall of pc case. The yelloy fan in this video don't do this. Maybe thats why temperature lower.
the fanless design looks like something from cyberpunk
XFX had some cards with customizable fans, afair.
it's their default feature. ngl, my XFX RX 580 runs cooler than that 1080Ti with stock fans... idle temp at 22°C (fan at 40%, since idle is 38%), and at max it will reach 55-57°C depending on the load.
Your welcome for the native solidworks part xD. Thank you so much for continuing to experiment with my bladeless design! I love it! I have all the way up to like version 5. Please reach out if you want to give any of them a shot!
Gpu fans be like: "I'm fast, I'm very fast, I'm like forest Gump."
You can also try dry ice and water for some smoke! With a small chunk and a few tablespoons of water you can have a full container for a good while
just trim the shroud so 120mm fans will fit, and mount 2 of the noctua motors and proceed as usual (:
Just mount a centrifugal axial 140 fan on the card that will blow air down and outward from the center
Just get 2 NF-A9x14 noctua's to butcher.
You don't have to trim the shroud at all You can just mount the noctua motors.
Ok. (being real I paused this 3:15 in) You could measure and find a way to mount 2x that noctua fan onto the card, make a mounting rig for it. THEN use 2x blades to cool it. I know it might sound sound off, but when using SFF (Small form factor) cases such as the NFC Skyreach Mini (and S4 mini) there are some that do this to de-shroud GPUS and just add Noctua fans to them for optimal cooling.
I voted and something happened LET'S GOOOO
Thank you to all whomst have liked my comment
Big fan of the normal fan showdown series you have been doing and to see you take that and apply it to GPU's is quite exciting. Can't wait to see what happens in the next video :)
cut out the hub of two noctuas, drill screw holes, mount!
@Major Hardware Fan hub motors that are small like that actually need cooling so the core windings don't overheat and burn out. Desktop fans have the same issue, if you've ran fans for a while then felt the back where the label is or the hub itself it's warm, the less airflow there is the hotter it will be and since the rear of those fans are touching a burning hot heatsink it's possible they overheated and they malfunctioned. Based on the RPMs you're getting, it's likely the control circuit (on the fans, under the hub) overheated and failed catastrophically.
Might be able to discover more with a disassembly of the hub itself. Board might be discolored on the back of the fan under the label and under the plastic.
I feel like you should lock the gpu frequency so that's not a variable
I agree, switch off the turbo boost on the GPU as well as any power saving/boosting options so it's a fair comparison.
Love the idea! A lot of stock GPU fans suck, especially noise wise. The 3D printing time lapse was great, by the way. More of those would be appreciated.
Hahahaha the bladeless GPU looks like a boombox XD
Remove the top cover, print a new one that fits 2x120mm standard fans, put the Noctua fans and you are done. Put the fan connectors on 12V directly (or whatever V you decide) and you are ready. Plus you now have a bunch of fan designs available.
I am quite sure you will be have more and more troubles with the stock fan motors and power supply if you stick to it.
Well, guess it's time for me to get to work.
Edit: nvm, RIP gpu
Edit 2: I take that back, to CAD I go!
yes, keep in mind fan direction because some of the manufacturers like to switch it up with opposite turning fans.
Try measuring the pressure
My Gainward Phantom GTX 980 had these fans that you could pop out the side of the shroud without disconnecting any cables so you could clean them. Yes they were puny 90mm (I think) things but for testing designs that might not be the worst thing.
6:35 Oooh....shout out to level1techs. Nice.
I can't remember if this was mentioned before, but the smoke test might be adding another variable depending on the type of smoke liquid used. Some of them do leave a greasy residue which can't really be blown off with a compressor or canned air like you can with dust, and will probably reduce the heat fins' ability to transmit heat into the air being passed through.
If this is a non-issue with the type of smoke liquid used then nevermind me, but if it is, it would probably give later contestants a bit of a disadvantage.
Protip : get an after market GPU cooler that takes regular case fans.
Why not try making an outer support ring on the new fan design. might help prevent centrifugal destabilization & could prevent the fan from blowing apart if that is your concern.
damn it! I was so excited to see my fan submission this week and it wasn't in this episode!
You can bypass the fan controller on the card and power the fans with your bench power supply, that way you can get CC or CA measurements per fan at a known volt/amps draw.
3:37 hoooooold on a sec... did u just say u revived a GPU with a oven? Please evaluate on that xD
Depending on what is wrong, heating your GPU in an oven can melt and resolder GPU board connections potentially reviving a dead board. Not my first recommendation on a malfunctioning GPU.
@@unoriginalproductions2591 For many old GPUs it seems like putting the GPU in the oven "repairs" it when the GPU itself is bad while it actually just extends its life for a few weeks. I’d recommend making sure reflowing is actually needed before attempting it.
people used to fix XB 360s that way also lol
Funny thing is;
"Baking" a GPU should, for all intents and purposes, *not* work. An oven just doesn't get hot enough to actually reflow solder.
Not to mention it might melt something important on the board.
And yet... It has worked for people, again and again.
@@The_Keeper really depends on the solder used, some can melt at a very low temp, easily achieved with an oven but reflowing is never the answer to every dead board
man! i love ur reactions! I'm fascinated by brushless motors and fans! i will participate once i finish the playlist :D
Y'know, for fans running at those RPM, its almost eerily quiet...
I had 2 ideas for fan prototypes, but I'm not really setup to design them.
So if you like the idea please design one and send it in.
1. Balanced Asymmetry:
The idea is based on tires, which use irregular spacing between the nobs, so there is not a single frequently, but many different, so it is nicer to listen to.
The idea therefore is to use many blades (~9-11) and distribute them unevenly around the center.
To counteract the offset center of mass, my idea was to have different width blades.
2. Idea is inspired by the very large spiral from one of the older videos.
My idea was to make the fan wider than the usual ones and to have a layer on the outside, which prevents air from blowing out.
The idea is, that it has a bigger inlet and can guide the air to the cooler.
Also the angle of the blades maybe should be shallow, to increase the pressure.
"this old 1080" .... cmon some people here still use 970 xD
770 reporting in.
760
Me still using APU in 2021
560 ti skyrim edition still going strong
@@Saji_0 i feel your feel bro :
I think the best idea would be to take a Arctic Accelero Xtreme IV an put some Noctua Fans on it to get a reliable test Setup that you can use on many different GPUs.
Major hardware is like:
'Fans are good...
... But they can be better"
GPU with a Noctua Fan (I mentioned it in community already as well as multiple previous videos): Just go for Morpheus aftermarket cooler. Besides of looking cool and having awesome performance, you can also attach whatever fans you want.
Wow, I called it and now it's happening xD
If you can actually get your hands on one, ASUS has collaborated with Noctua on an RTX 3070 and RTX 3080. So, perhaps you can finally revive this idea now.
There are 3rd party coolers for GPUs that allow you to fit 120mm fans on them, would be easy to attach noctuas to them to make a consistent test bench, problem is that it takes away the curiosity of fixing stock coolers with different fans.
I have a Raijintek Morpheus II on my Vega 64. It's an aftermarket aircooler like Arctic also make and it allows you to run aftermarket fans on your GPU. Mine has 2 nice Noiseblocker 120mm fans on it and it's really good. It runs at about 50-60° depending on ambient temperature and load, which is a significant improvement over the stock AMD cooler (obviously).
User a riser cable so you can run the gpu far away from the test bench to avoid accidents inside the case, and so it would have enough headroom for crazy large fan designs
I got a flsun delta because you like your delta so much. It works great and has awesome detail!
When you put the reflective tape on, You should put it on the motor so it minimizes the imbalance created.
Yes tape is light, but the whole thing itself is pretty light and the further you have it from the center the more of an effect the weight has.
That's why that fan is bouncing when it wasn't bouncing before
There's a high chance you tripped a polymer fuse due to too high current required to run the heavier bladeless fan.
Polymer fuses heat up and cut power, once they cool off they allow current to pass again.
This is my favorite channel on UA-cam!
I like the different colors of each fan it's better to recognize
Definitely a great idea! Best option to me would be slapping the motor assembly from the Noctua onto the GPU. Doesn't seem too hard either. Would just need to make some sort of bracket. Might already be one out there
You can power the fans from a seperate power supply to control the speed and that way you could see the power draw for every fan design
Maybe consider an external fan controller like the corsair commander? or use a uC like an Arduino for some easy PWM? Anyway, I'm just so excited to see this series continue. Fabulous creativity and interaction with your audience. This is my favorite channel on youtube at the moment.
Noctua does sell fans in an assortment of sizes. You could try using the hubs from a smaller size. Aftermarket coolers also exist so that’s another option.
Please add specs for gpu case so we can print out custom gpu shrouds to match our crazy gpu fans
I’m no good with modeling, but I’d love to see what would happen if you combined the Bladeless design with a traditional fan. You could adjust the angle of attack on the connecting splines so they function like traditional blades to be the primary air mover, but also keep the dome design from the Bladeless to capture the current lost to centrifugal force.
A would print a cone cap for the bladeless fan too, this would improve the looks. The double turbine looks amazing, hope to see a gpu fan season 1!
WOW!!! 5k rpm means you had those fans VERY well balanced! Seriously. That is amazing on many levels!
It actually looks so sick with these two bladeless. Love it !
I can tell you that your videos and fans made my head spins around. Lol
In just one word.
Awesome!
Transplanting the noctua motors would be an interesting standalone video, but i think best course of action is an aftermarket cooler that already has 120mm fans (maybe transplant the noctua motors anyway, so it's just one file to keep track of and previous fans can be tested more easily)
Airflow and airflow against pressure are 2 very different things.
You wouldn't think that a radiator specifically designed to have air flowing thru it would restrict airflow all that much, but it really doesn't take much at all to cause major differences.
glad to see something being printed on the Q5, been loving mine since Aug good to see you still using it.
Maybe a powercolor GPU? Seems like they usually have some of the most robust cooling solutions.
I hope you're able to iron out all the little bugs so we can have a full on GPU fan showdown.
I would suggest getting some kind of riser cable and card mount. this way you can isolate sound from CPU/GPU better when doing noise tests, and other fun filming stuff like dumping the smoke directly into the cooler.
Let it ride. Do the full speed test. That's what we all asked for on the A12.
Love the videos and the work that you do!
Man, you are REALLY obsessed with that biohazard fan. You pull it out any time you need a display piece. (Pst: I understand, its a beautiful fan.)
i actually have a 120mm fan which seems to have a built in controller with some interesting routines programmed into it , for when it detects scenarios like the fan isnt spinning due to an obstruction; it would cut power and restart the fan 4 times before giving up
perhaps these GPU fans have similar logic and hardware which detects when e.g. a blade has broken off, or if a motor coil is burning up?
maybe the reasoning for that is the GPU's own thermal shutdown is a lot more controlled and harmless than the electrical, mechanical or even fire risks posed by forcing a faulty fan to continue running
What you're looking for is a morpheus ii cooler, it allows you to strap on 120mm fans onto the heatsink.
11:39 When the fan motors started spinning and the MGS alert sound went off. I got a text at the same time and that's my text alert sound as well. DOUBLE SHOCKED!
Noctua fans on the gpu would work best for sure, but I think that the factor that would make a gpu fan showdown interesting is the high rpm nature of gpu fans. You could maybe limit fan height/mass to not overload the motors and create some design restraints to differentiate it from the normal one.
Oh and maybe the fans might lose friction on the plastic hub and the hub would spin inside a stationary fan. That could be a potential issue to resolve with this..
Great stuff as always James! Looking forward to the next series for GPU fans.
You could always looks at that third party Raijintek cooler (the morpheus). It’s a pain in the ass to install (and I do NOT recommend using their included thermal adhesive because it doesn’t actually hold any of the included heatsinks in place) but it would allow you to use two noctua fans instead of needing to use whatever the included motors are on the GPU.
I like the 30 blade design I was a jet engine mechanic on b 52 h aircraft. The problem with it is that its for compressing air molecules in stages. And on the tf33 there is 16 stages but only 15 actual stages the first 4 is fans. The first 2 fans is driven by the last 2 turban stages by a shift that runs though the center on the engine supported by precision bearings.
Would it be possible to make a fan blade that is intake and transitions to turban to drive itself to a degree to get higher rpms
The turban side should be 20 to 40 % less coverage of intake to allow intake air to bypass
i....don't even know what a GPU is... but, this channel is captivating.
