@@_-Montana-_ To be fair. NorthridgeFix, according to his videos has to repair a handful of whatever comes into his shop on a daily basis. He may be able to do more in depth repairs but chooses not to in order to get repair jobs in and out very quickly. He doesn't seem to lack for jobs so he can be picky what he works on.

I realize this was about two months ago but what do you mean he did that for free! He seriously did that for free? Whoever owns that card should have sent this man a couple hundred dollars for fixing it as a tip.
@@brianpratt2432 Because he will not warranty this repair, as it is highly likely that it will crack again and fail, if the card isn't handled / installed very delicately!
He explains in the video. He no longer warrantees or accepts this sort of repair because the card becomes fragile after this kind of repair, installing it without great care will just damage the card again and put it back on the repair bench again. Identifying problems and rebuilding broken traces/pads deep inside a multi-layer PCB does require skill, and a certain temper. Anyone can learn how to solder "professionally" in about a week - not everyone can do this kind of detailed repair.
I didn't even think this kind of repair was possible, much less privately. I thought any kind of repair work that would just not be feasible to perform would have no instrumentation to support such workflow. I'm glad to have seen this amazing process and I'm no less amazed by the skill it requires. I mean, this looks like it requires VERY steady hands. Amazing, all of it!
It can be very difficult, especially on multilayer PCBs. There's often a way, especially with schematics, but with things like graphics cards they can be disturbed easily and break connections again! Single or dual sided is much easier, the times i've had to fix, glue and reconnect traces on abused electronics i lost count of lol
Without KirsFix channel, I would've never attempted, let alone repaired my own 3080ti with the same issue. This channel, and TechCemetary taught me SOOOOOO much about GPU repair. Prior to these guys, I've only been able to do SMD diagnostic and repair. After, I've fixed PCB layer issues that I never would've been able to fix, nor wanted to fix in the past.
The reason for the pads not being ripped off on these boards is probably the use of soldermask defined pad technology (annoyingly shortened to SMD!), where the soldermask aperture size is negative in relation to the pad size, so that the hole in the solder mask is actually smaller than the copper pad underneath. This leaves a "ring" of soldermask defining the shape and size of the pad, rather than the normal process where there's a small gap between the pad and the soldermask. This is typically done on BGA & CSP footprints for exactly this reason: it helps mechanically secure the small pads to the PCB, making it more resistant to lifted pads from shocks and vibration. When there's damage it typically breaks the chip rather than the board, making repair possible. The downside is that it's harder to manufacture, which makes it more expensive, but in cases where the board is going to be (mis)handled a lot it makes sense to use this technology. Phones, for example, use it pretty much everywhere.
Ahh... Interesting info there. Thank you. nVidia should adopt this process immediately. It would give Huang an excuse to raise prices a bit more. Or we could start securing the GFX to the case, and then mount the motherboard onto the GFX.
That's genius. It's also something I can start doing at home with DIY etched boards and UV-cure solder... at least, I can start *trying* to intentionally do that :D
@@81formann I like the idea of securing the card to the case somewhere to avoid these types of damages. Riser cables could come with cases or motherboards this way.
So, you don't only have amazing repair skills, but also a caring heart. Thank you on behalf of this customer and all of us for doing this repair. As you rightly say, it is impossible to warranty this type of repair. Obviously, you cannot run a business without getting paid for your work. So, I have made a small donation to your channel, and encourage others to do the same. Together, we can aid Kris-fix to repair some cards of this type without being out of pocket.
@@jasonriddell Well yeah, because this is A LOT of work to fix a single card. A lot of work is a lot of time, and a lot of time spent working on a single card is a lot of wasted money. This level of repair can easily far exceed the worth of the card itself.
I am an electrical engineer, I understand what you are doing, and you are a magician. That is insane! I thought I had some basic soldering skills myself (0.5mm Pitch SMD, bottom side Thermal Pads, all at home with cheapest equipment), but that is a level I would've thought impossible. You have my greatest respect!
Can you do CPU pins too? That's tough. I can do outer or inner edges. I don't even bother with those in the middle of an area unless I can create a corridor be removing one on an edge
I am surprised that you only have 18k subscribers. You explain everything in great detail, you explain it so everyone can understand. The quality of the videos is great.
just a matter of time my friend, just a matter of time. From 10k to 100k takes longer than from 100k to 1M. In 2 years it will exceed 1M subscribers. Give it a little time.
It's incredible what you can do with these repairs, Kris. I've been watching your channel for a while now, and I’m glad I found you. Your repairs are always thorough and exacting a consummate professional. I wish you the happiest holidays and the best in the coming year. Take care, and we’ll see you at the next repair.
The most disgusting thing is that a lot have far to few slot blends they use … totally rip off If you told me 10 years ago where we build into cases 500 watt gpus that weight around 10kilo on 2-3 slots i would laughed and said stop joking … they need to make better designs way more structure
One thought as to why the AMD boards might have stronger pad adhesion vs. the Nvidia ones is that AMD might be using BGA footprints that overlap the soldermask over the copper layer a bit. Overlapping the soldermask is apparently a common technique in smartphones to improve the mechanical strength of the BGA connection by using the soldermask to retain the copper. I think that you can see them doing this at 15:00. (edit: I looked at your most recent Asus 4090 video and it doesn't look like Nvidia is overlapping the soldermask on top of the BGA land, so this is probably a reasonable hypothesis as to what's retaining AMD pads better.)
you are right. and the comparison is not fair, Nvidias Ref boards the best of all. what gigabyte asus msi etc. do is on their own, AMD is not producing them at all. Nvidia has more advanved PCB which are necessary for the GDDR6x VRAM. he maybe don't know that but the conclusion was wrong.
@@PrefoX Well, this trick with the soldermask doesn't really affect the SI of the signal - you can absolutely still do it while still hitting the targets for GDDR6X and higher. It doesn't even change the cost of the PCB any - it's just a little attention to detail thing when doing footprint design that can improve durability.
Did I really just see someone repair a 12 layer PCB with multiple cracks? 😮Anyone who has done something similar as a profession must be either ashamed or in awe of the repair.

Das ist komplett krank. Ich bin selbst ziemlich "hands on" was IT Probleme angeht aber so eine Reparatur würde ich mir nicht mal in meinen wildesten Träumen vorstellen. Und wenn mich jemand danach fragt, hätte ich immer gesagt "sorry Kolleg da hast du leider verloren, keine Chance." Die Frage ist aber, was hätte diese Reparatur gekostet? Das müssen doch safe mindestens ein paar hundert Euro sein.
Are you for real bro? How on earth is this kind of a repair even possible. If anyone can't be positive after seeing a video like this, what will make them positive. NOTHING!! Your work is next level dude. It's like superhuman work.
Great work as always. I'm sure the reason they tend to fail after these types of repairs is because the crack still exists in the board, so it's structurally compromised. Any stress will go straight back to the repair area first. Solder mask isn't very strong stuff when compared to layered fiberglass and the mask doesn't get into the crack. Using a low viscosity epoxy resin with the assistance of a vacuum chamber would help in getting a strong material into the crack and restore some structural integrity. Normally this wouldn't be worthwhile however these types of failures have become so common, and the trend of big heavy coolers doesn't seem to be going away.
That's the most crazy repair I've seen on TH-cam. Me "that's cracked right through, you can't repair that"... Wrong. Me "Loads of pads ripped off the card under the ram, it's junk"... Wrong.

Hallo KrisFix und fröhliche Weihnachten :) Deine Arbeit ist unglaublich und wir wissen sie immer wieder aufs neue zu schätzen. Was Du leistest ist einfach Klasse. Beste Grüße und Danke für Deine Arbeit und die tollen Videos :)
Wow, ich hätte es niemals für möglich gehalten, dass man wirklich handwerklich an solchen Platinen arbeiten kann. Allergrößten Respekt dafür. Sehr beeindruckend anzuschauen.
Mit dem richtigen Werkzeug geht fast alles. Diese ganz kleinen SMDs habe ich bereits öfters schon als Jugendlicher gelötet - einmal einen damals sehr teuren 1GB DDR Ram, und ebenso meine 9800 GTX. Funktionieren bis heute noch. ;-)
I got to this channel from DerBauer, I never thought I would find this stuff that interesting but here we are! It's very interesting as a Software Engineering major who has to do classes dealing with electrical engineering and the like. Very cool to see these high level repairs!
Ich komme über "DerBauer" und dessen defekte Karte zu dir und finde es einfach nur beeindruckend welche Skills du in diesem Bereich hast. Ist einfach interessant zum zuschauen. :)
Ich muss ehrlich sagen, krasse Arbeit. Ich kann zwar auch elektronik reparieren, aber nicht auf so einem Level wie du, hätte gar nicht die Geduld dazu und das können.
Kris' stuff just came up in my recommended on my home page after being a fan of debauer, and I have to say that I love it. Feels like the old Louis Rossman before he started to get into the economics and politics of his area and repairs, which I fully support, but sometimes just don't have the right mind-frame to focus on. So to have someone doing these kinds of repairs, completely different area too, and explaining their processes and explaining how to do it with the right tools is amazing and I love it. Hope more people find you, Kris, because you're doing amazing work and it's amazing to see you work and explain the process and solution too.
Wow, this isn't just expertise, this is ART. i can barely put a warhammer mini together without shaking and here you are moving micrometer sized traces around. Amazing.
Amazing repair! You really went the extra mile on this one. Burrowing into a 10 layer board is well beyond what I can do, and it's a testament to an amazing level of skill and patience.
Deine Arbeit belohnt dich mit dem Erfolg und zu wissen was man machen kann. Auch wenn das heutige Gewährleistungs system sowas fast nicht zulässt. Sehr befriedigend zu zu sehen. Du bist der beste Theodor. Ein frohes neues Jahr und merry chrismas.
Just curious, if a PCB is beyond repairability, would it be possible to just wait for another card to come by with a dead core, and then switch the cores on both cards so you end up with one working card? Or can you not mix and match cores between different vendors. For example putting a working core of a ASUS 6900XT onto the PCB of an XFX 6900XT. Would be a nice Frankstein card if that works. It would feel like a waste if a card is thrown away because only the PCB is broken. The core is most valuable I would say, especially on modern card.
that is what I was thinking and "revive" a dead core card with this being the "donor" I expect the core to be the same for every "AIB" as long as it is the same class of card IE 6900 and NOT 6950 OR LHR/NON LHR 3080 cards
thanks to der8auer i discovered your channel, now i can't wait to watch every repair you do, because of you i learned so much about traces, reballing, and generally how to fix a graphics card. thank you kris, thank you der8auer
I follow many different repair channels and I must say this was hands down the most amazing repair I've ever seen; to go that far and manage to save the card was truly astonishing, bravo. You got yourself a new subscriber.
"Hat from a head". This is nice to watch. Especially with that music in the background. Great job! 10/10 points from me for taking and successfully accomplishing this challenge.
It’s quite common to sandwich data lines between ground plane layers to make them less susceptible to electromagnetic interference (ground acts as an EMI shield) which probably makes grinding even harder if you need to go deep into an eight or twelve layer PCB I suppose
That's not at all how it works. It's about coupling, not shielding. If you go down the path of PCB design thinking it's shielded, you will create massive problems that other people will get paid well to fix. 😏
Correct me if I'm wrong, but did that machine placing the ram ic show you both the PCB and the ram pads so you could align them for correct placement? If so, that's incredible!!!
its mind blowing how precise your work is. its hard to visualise how small your work area is through that microscope and yet you make it look like you are just reconnecting normal pcb traces. its easy to forget you are soldering microscopic data lines on a high end gpu 5 pcb layers deep. very impressive
Hi, I'm writing from Italy ... the work you do is incredible 🤩 ... I honestly didn't think it was possible to repair sophisticated components such as video cards ... I recently bought a zotac rtx 3080ti which was used to mine and if I need a repair in the future, I will certainly contact you 👍👋
Kris, what would likely cause damage to the memory modules like this? The physical bending of the card seperating the memory chip and the PCB causing electrical shorts?
The same force that damaged the slot and bent the PCB would rip pads from the memory modules. This is why some manufacturers started using underfill on the memory chips closest to the slot, moving memory chips away from the slot area, and moving all BGA components in general away from the slot area.
Amazing repair that requires a lot of precise patient work! And it is amazing how manufacturers are routing so many traces at the edge of fragile PCB part (even under the screw pressure points) :/
Incredible. I did not believe work like this was physically possible. I had some idea how complex modern GPUs were but seeing you go through the layers under a microscope was something else entirely. This is more than extreme proficiency with the tools and workpiece, this is artisan craftsmanship.
Very lucky on those RAM chips, I thought for sure some pads would be MIA. Nice work. There does have to be a line you draw, unless money isn't an issue for the person but then if it weren't they'd probably just grab a new card. I think this is close to that line because the cost of this repair had to pretty high.
i would love to see at the end of the video what it coast. By my self, i have the ''Inno3D Geforce RTX 2080 TI ichill Black'' and i send it 3 times to Inno3D, they replace the cooler, but the main problem is still there. Its cool at 55c on idle but its not the cooler, its the card for sure. You can start and run pc till the desktop but if you start something it shut down immediately, the temperature goes instantly over the 90c and it turns off, i also had random pixels all over the screen, glitches and i dont know all the names of this issues. The card has no longer guaranteed and nothing else, but Inno3D try to help anyway - im really thankfull for that. Now its way more over a half year without gaming for me.. i really hope you can help me. Thank you and Inno3D for your support and help! By the way, it was Inno3D, they told me about you, so here i am. Im from germany too, but i leave this comment in english. (sorry for my bad english) I really hope so much for help. I saw few videos of you and i really enjoy it too see how you repair. Greetings, Lukas
Unfassbar! Der absolute Hammer, deine Reparaturen zu verfolgen. Schon sehr viel auf diesem Channel gelernt und weiterhin sehr interessiert am Thema. Danke für's Teilen 👍
awesome video, very nice work! i also quite liked the song you played at around 16:00, it reminded me of one of my favorites you might like thats very similar "Immanuel - Tony Anderson"
If traces are in pairs, they are most likely differential pairs. Removing a layer of copper will greatly change the impedance of those signals, affecting signal integrity. Signals bouncing back and forth would cause more issues.
Wow... it take a lot to impress me... just let me say your workmanship is amazing. I have only seen one other person who does such a good job. Nice work. A+
I'm glad I always picked cases where they turn the MB tray so that GPUs are mounted vertically. With how heavy cards got over the last few years, mounting them horizontally just asks for problems. :D
@@mberring1 Some SIlverstone cases have that configuration and my gaming case is the Thermaltake Tower 900, also vertical configuration ;) The ridiculous thing is, I have a RTX4090 gaming OC from gigabyte and despite the huge Tt case, it barely cleared the middle section with the HDD cage and fan ontop.

Mit dem richtigen Werkzeug geht fast alles. Diese ganz kleinen SMDs habe ich bereits öfters schon als Jugendlicher gelötet - einmal einen damals sehr teuren 1GB DDR Ram, und ebenso meine 9800 GTX. Funktionieren bis heute noch. ;-)
I got to this channel from DerBauer, I never thought I would find this stuff that interesting but here we are! It's very interesting as a Software Engineering major who has to do classes dealing with electrical engineering and the like. Very cool to see these high level repairs!
I came here because of DerBauer and am a "fan" of Louis Rossmans MAC repair videos but this is NEXT LEVEL repairs
Was eine Arbeit, natürlich kann man alles reparieren aber das ist schon nicht ohne gewesen.
Frohe Weihnachten und guten Rutsch!:)
guten Rutsch :)
Ich komme über "DerBauer" und dessen defekte Karte zu dir und finde es einfach nur beeindruckend welche Skills du in diesem Bereich hast. Ist einfach interessant zum zuschauen. :)
Ich muss ehrlich sagen, krasse Arbeit. Ich kann zwar auch elektronik reparieren, aber nicht auf so einem Level wie du, hätte gar nicht die Geduld dazu und das können.
Kris' stuff just came up in my recommended on my home page after being a fan of debauer, and I have to say that I love it. Feels like the old Louis Rossman before he started to get into the economics and politics of his area and repairs, which I fully support, but sometimes just don't have the right mind-frame to focus on. So to have someone doing these kinds of repairs, completely different area too, and explaining their processes and explaining how to do it with the right tools is amazing and I love it. Hope more people find you, Kris, because you're doing amazing work and it's amazing to see you work and explain the process and solution too.
Killin it man. I had no idea things like this were possible.
Wow, this isn't just expertise, this is ART. i can barely put a warhammer mini together without shaking and here you are moving micrometer sized traces around. Amazing.
This is just insane, thats truly a special skill and a lost art. Almost nobody can do such repairs in todays world.
Great work!
Lost art? It was never an art. So many layers on a PCB is very much a modern tech thing.
@@Steamrick my statement was based on the fact, that he could repair such damage, that is lost art. Not the multilayered pcb.
Merci pour toutes tes vidéos et joyeux noël🎅 et Bonne année 2023
That's one hell of a repair. Never seen anything like it. Very good content keep up the excellent work!
Amazing repair! You really went the extra mile on this one. Burrowing into a 10 layer board is well beyond what I can do, and it's a testament to an amazing level of skill and patience.
This is absolutely stellar. Amazing video. No nonsense, straight to the point and excellent workmanship.
Deine Arbeit belohnt dich mit dem Erfolg und zu wissen was man machen kann. Auch wenn das heutige Gewährleistungs system sowas fast nicht zulässt. Sehr befriedigend zu zu sehen. Du bist der beste Theodor. Ein frohes neues Jahr und merry chrismas.
Amazing work! Great videos! To the point, clear, detailed, and masterful expertise. 10/10 channel
Just curious, if a PCB is beyond repairability, would it be possible to just wait for another card to come by with a dead core, and then switch the cores on both cards so you end up with one working card? Or can you not mix and match cores between different vendors. For example putting a working core of a ASUS 6900XT onto the PCB of an XFX 6900XT. Would be a nice Frankstein card if that works. It would feel like a waste if a card is thrown away because only the PCB is broken. The core is most valuable I would say, especially on modern card.
that is what I was thinking and "revive" a dead core card with this being the "donor" I expect the core to be the same for every "AIB" as long as it is the same class of card IE 6900 and NOT 6950 OR LHR/NON LHR 3080 cards
thanks to der8auer i discovered your channel, now i can't wait to watch every repair you do, because of you i learned so much about traces, reballing, and generally how to fix a graphics card. thank you kris, thank you der8auer
I follow many different repair channels and I must say this was hands down the most amazing repair I've ever seen; to go that far and manage to save the card was truly astonishing, bravo. You got yourself a new subscriber.
"Hat from a head". This is nice to watch. Especially with that music in the background. Great job! 10/10 points from me for taking and successfully accomplishing this challenge.
Very impressive repair! I would not have thought it would be possible to repair that kind of damage
This is some really fascinating stuff..... happy holidays
It’s quite common to sandwich data lines between ground plane layers to make them less susceptible to electromagnetic interference (ground acts as an EMI shield) which probably makes grinding even harder if you need to go deep into an eight or twelve layer PCB I suppose
That's not at all how it works. It's about coupling, not shielding. If you go down the path of PCB design thinking it's shielded, you will create massive problems that other people will get paid well to fix. 😏
Wow amazing fix, patience of a saint, and the skill like none I've seen on youtube, congrats and happy new year.
What’s going on with bauers 4090? THAT is the video we want to see.
He will make a video about it
Kudos @Kris, it never hurts to remind people/public what a pro repair looks like.
Correct me if I'm wrong, but did that machine placing the ram ic show you both the PCB and the ram pads so you could align them for correct placement? If so, that's incredible!!!
yeah it did! Im so jealous lol!
its mind blowing how precise your work is. its hard to visualise how small your work area is through that microscope and yet you make it look like you are just reconnecting normal pcb traces. its easy to forget you are soldering microscopic data lines on a high end gpu 5 pcb layers deep. very impressive
Hi, I'm writing from Italy ... the work you do is incredible 🤩 ... I honestly didn't think it was possible to repair sophisticated components such as video cards ... I recently bought a zotac rtx 3080ti which was used to mine and if I need a repair in the future, I will certainly contact you 👍👋
It's almost as if I was watching a surgeon performing some heart bypass surgery.
Kris, what would likely cause damage to the memory modules like this? The physical bending of the card seperating the memory chip and the PCB causing electrical shorts?
Maybe a bad technician tired to repair the card before Cris?
The same force that damaged the slot and bent the PCB would rip pads from the memory modules. This is why some manufacturers started using underfill on the memory chips closest to the slot, moving memory chips away from the slot area, and moving all BGA components in general away from the slot area.
@@siliconalleyelectronics187 thanks for the comment, good info.
You are the best Kris, thank you for teaching us so much stuff. Happy new year from Argentina!
Amazing repair that requires a lot of precise patient work!
And it is amazing how manufacturers are routing so many traces at the edge of fragile PCB part (even under the screw pressure points) :/
Amazing, yes. You might even say - amazingly curious. :- )
dude..... no words, first time ever seing such repair. 99% other people wouldve just send to junk. BIG THUMBS UP!!!!!!!!!!!!!!!!!!!!!!!!!!
Incredible. I did not believe work like this was physically possible. I had some idea how complex modern GPUs were but seeing you go through the layers under a microscope was something else entirely. This is more than extreme proficiency with the tools and workpiece, this is artisan craftsmanship.
Hi Theodore. You did a great thing for this customer especially considering it's Christmas. This will be a great present for him.
Very lucky on those RAM chips, I thought for sure some pads would be MIA. Nice work. There does have to be a line you draw, unless money isn't an issue for the person but then if it weren't they'd probably just grab a new card. I think this is close to that line because the cost of this repair had to pretty high.
It's not only this but imagine you do all the work perfectly and at the end of all that perfectly done work, the card still isn't working properly.
Most shops won't attempt repairs like this. Not worth the time. High risk little reward.
Holy moly! Невероятни умения и търпение. Благодаря за обяснението и т.н. Иска ми се да знаех и 1/3 от нещата които сте забравил за електроника!
i would love to see at the end of the video what it coast. By my self, i have the ''Inno3D Geforce RTX 2080 TI ichill Black'' and i send it 3 times to Inno3D, they replace the cooler, but the main problem is still there. Its cool at 55c on idle but its not the cooler, its the card for sure. You can start and run pc till the desktop but if you start something it shut down immediately, the temperature goes instantly over the 90c and it turns off, i also had random pixels all over the screen, glitches and i dont know all the names of this issues. The card has no longer guaranteed and nothing else, but Inno3D try to help anyway - im really thankfull for that. Now its way more over a half year without gaming for me.. i really hope you can help me. Thank you and Inno3D for your support and help! By the way, it was Inno3D, they told me about you, so here i am. Im from germany too, but i leave this comment in english. (sorry for my bad english)
I really hope so much for help. I saw few videos of you and i really enjoy it too see how you repair. Greetings, Lukas
Well. Let's get you paid. ;)
Absolutely insane skills. Very nice!
Do you use some drugs to hold your hand that steady? Looks more complicated like an operation on the heart. ❤️👌
Neurosurgeon steady hands, indeed... Some people just have them - easy to lose them as well.
Unfassbar! Der absolute Hammer, deine Reparaturen zu verfolgen. Schon sehr viel auf diesem Channel gelernt und weiterhin sehr interessiert am Thema. Danke für's Teilen 👍
You get a subscription for this one, I have watched a few of your videos, but this one really deserves a subscription. Keep up the great work.
Fantastic filming, great repair skills and a huge heart. May your generosity be rewarded tenfold.
Next level repair. You got a new sub
I'm so glad TH-cam recommended you and Tony to me. This stuff is highly educating and fun to watch.
awesome video, very nice work! i also quite liked the song you played at around 16:00, it reminded me of one of my favorites you might like thats very similar "Immanuel - Tony Anderson"
If traces are in pairs, they are most likely differential pairs. Removing a layer of copper will greatly change the impedance of those signals, affecting signal integrity. Signals bouncing back and forth would cause more issues.
Fortunately, the copper is removed for only a few millimeters.
That's the most proffesional repair I ever seen. Amazing. This repair, for me, looks impossible, even after I've watched it done. My deep respect.
I have never seen multilayer board repair. Ever. I've never even attempted it. Amazing work!
You are an absolute magician ! Big respect... also your english improved a lot since your beginnings :) . Keep up the great content
Magician man! Really impressive work!
the level of skill displayed in this video is mind blowing. you are truly amazing at what you do.
Wow... it take a lot to impress me... just let me say your workmanship is amazing. I have only seen one other person who does such a good job. Nice work. A+
I'm glad I always picked cases where they turn the MB tray so that GPUs are mounted vertically. With how heavy cards got over the last few years, mounting them horizontally just asks for problems. :D
What cases are you referring to, if I may ask? I'm only aware of the Dark flash v22 case, are there others?
@@mberring1 Some SIlverstone cases have that configuration and my gaming case is the Thermaltake Tower 900, also vertical configuration ;)
The ridiculous thing is, I have a RTX4090 gaming OC from gigabyte and despite the huge Tt case, it barely cleared the middle section with the HDD cage and fan ontop.
Very impressive repair, I love to see stuff like this get fixed instead of going to a landfill or something
Absolute legend. Much respect
I have never seen your channel before. This is AMAZING work! So intricate! I watched the entire video! Thank you so much for sharing this with us!
