We FIXED a DEAD CPU!!

you just finished up your new gaming rig you boot it up and nothing in desperation you pull out your CPU and you see it the pins they're gone accidents will happen guys believe me I totally get it and sometimes accidents happen to you one of our fine viewers Ethan I hope you're doing well had a little accident a couple months back with this shiny new rise in 730 700 X and he managed to break three of the pins clean off now sometimes you'll get lucky and the pins are just bent and they can be easily strained other times you'll get just a little bit lucky and you can't straighten them but you pop it in and oh great it turns out the broken pin was a non-essential extra grounding pan or reserved pin or something like that other times you press the power button and nada well that was Ethan but fortunately he still had a little bit of luck to spare and treated his completely non functioning chip for some merch from us so that we could take a crack at fixing it with just a few cheap and easy to get tools and some other supplies that you might have lying around your house speaking of around your house Grizzly's oh jeez I hope not but third we'll Grizzlies conductor not liquid metal Tim offers maximum cooling performance check it out and keep things cool at the link in the video description [Music] before we start let's talk about the tools we're gonna need a magnifying late like this would be ideal but a regular magnifying glass will do in a pinch and if you go that route you're also gonna need good light because you need to see the tiny teeny little pins that we're gonna be working with so a desk lamp or ideally too so that it's illuminated from two different angles would be freakin fantastic next you're gonna need a hot-air solder stick can you stay please stay good boy next up you'll need a hot-air solder or SMD Reaver station you can think of this kind of like a regular soldering iron but with a fan attached to it so instead of poking and prodding at the things you're trying to solder potentially knocking them over or you know accidentally dabbing the tip into the PCB we're just going to be able to take the hot air that comes out of the tip of it and kind of heat up the entire area that we're trying to work on without touching it now normally these include tips we seem to have misplaced ours and the replacement tips weren't to prime item so we're just going to Yolo it with the big old fat tip you'll need a good set of tweezers we really like these ones from iFixit as well as some flux this will help our solder flow very nicely as we are putting the pins back on we're gonna need some solder masks these are available cheaply on sites like Aliexpress or ebay the one we're gonna need in particular is the point six five millimeter pitch one because that matches the pin arrangement of our CPU as you can imagine you're not gonna want to blow super hot air onto your kitchen countertop so we recommend something like a couple of fireplace bricks like this or failing that a nice large sheet of many layers of aluminum foil so something like five six seven of them and anywhere from kind of seven inches or around 20 centimeters square it's really important to make sure that your entire work area is clean and clear because the last thing you want to be doing is bumping something over or accidentally touching a hot surface now that all our tools are set up all we need is the donor donar what the it's not a big deal the things already dead you know what's good I'm gonna embrace it bring in the donor our first order of business is to harvest some good pins so we're gonna set our station to somewhere between 300 and 350 degrees Celsius here's a hot tip by the way hey II get it the hotter the temperature the faster the solder melts but also the faster you can damage your components slowest move smooth is fast grab your tweezers and pick a good candidate for a straight pin that you want to pull off start to heat up the area and don't burn yourself when you see the solder at the base of the pins get really shiny that means it is melted so pick off the good pins that you want to use grab an extra one or two keep the area hot until you're done then place the pins off to the side to cool is this taking too long again okay I swear to God if these don't melt are you well we got one new there's one and is another one yeah hasn't anyone been getting the hang of this boys the last thing you want to do while you're at this he's pulled too hard cuz then you can actually rip off the pad and once the copper contact point comes up off the CPU you are done well that's more important for the one that's not already dead I guess there's a perfect example see that we ripped off the pad if we do that on our working CPU game over ladies and gentlemen one thing to watch out for guys the CPU and the end of your tweezers are going to be hot don't touch them that's not a smart idea let them cool down for a few minutes and while you're waiting why don't you refresh yourself with some ice-cold water LT t store confidence I'm gonna be the next Billy Mays hey it's lines mastered here with extra heavy UDL can foil it slices it dices oh my god my fingers at this point we strongly recommend practicing reattaching pins to your donor CPU before we strongly recommend reattaching them to your donor CPU till your comfortable with the whole process now I don't have time for that somebody ordered some tech tips on uber eats and these babies ain't gonna deliver themselves so we're going straight to our new CPU hoping for the best here it's we're just gonna go ahead and pop that on make sure that is yep okay that works just fine and this gives us a really good look at the broken off pins on our CPU I don't know what Ethan did here because they are straight almost cleanly snapped off which unfortunately is gonna make the job of removing the pins from the pads a little bit trickier even with these teeny-tiny new tweezers it's gonna be hard to get a good grip on those danged Ethan I really hope I don't knock off any additional pins too while I'm at it I actually kind of wish I had practiced before doing this I mean you know the saying though practice is for chumps hey number two is out this last one is the hardest one come on yes well I just got to find where that first pin fell how hots the CPU ah yeah okay yeah so it's in there oh ah dang it Brandon can you see this get out yeah I got this I got this can you see it there oh man I think it might have stuck back on there you know what and it's gone perfect twenty bucks this thing works when I'm done I don't actually bet money though so it'll have to be like lunch all right so now we're gonna put our mask on for real there you go that's an important step then we're gonna add a little bit of flux just around the pins that we're trying to reattach here now's a great time to clean our pins so just a little bit of isopropyl alcohol and some tissue paper wipe the contact pad there clean pins will adhere a little bit better something to notice that the flux we're using is a bit of a thicker flux that's gonna help hold the pins in place while we are heating up the CPU now let's go ahead and stick our pins where they go oh why am I doing this left-handed now you can do the pins one at a time but we are opting to position all of the pins on the CPU so we're just going to go full hail-mary heat the whole thing up and hope they all kind of snap back into place here oh crap I just want to I just want to push this one over a little bit why am I doing this left-handed well I lied I know the answer the answer is that it's because I need to show the camera okay I'm pretty sure that's about as good as it's gonna get right now oh time to heat this baby up oh and it blew them over okay we need more flux more flux okay get off there all of you there you go you got like a flux booger on there alright this is not easier okay I think that's where that one goes my certainty level is very low yeah I can't put I think too much flux on so we're gonna try to melt our flux a little bit to give give us a better look at what the crap we're dealing with here yeah it's not getting easier man you guys could watch that other guys guide on this he doesn't better than I do it okay I'm doing this right and if I give up I can't I can't show you guys what I'm doing cuz I need to do this with my my dominant hand can I just put this on first and then slip the mask over top so another thing is I think last time I kind of blew it over whereas this time I'm gonna come straight down on it it's gonna snap into place why do I doubt that hold on Hart bail Hart bail I'm bailing okay none of those are attached okay new plan we are putting that we're putting all the pins on and slipping the solder mask overtop cuz I don't think these pads actually slip through here they do not well that's good oh my god we could just put the pins in the solder mask Nickolas bad instructions holy crap that's how you're supposed to do it this is so much easier so all we're gonna do now is line the pins up in the solder mask did you manage to reattach pins the way you were doing it yeah well you're a genius I actually cannot do this with this stupid light in my way okay there we go getting hot in here so take off all your pins I don't know if I would describe them as having snapped into place but they're definitely pretty straight like we should be good by now right all right I'm gonna let it cool down we're gonna pull the mask off and see if the solder soldered let me use my very sophisticated cooling technique here you go what do you think all the pins gonna come up they stayed that's a good sign but that doesn't necessarily mean they are attached nope that one's loose af they're all loose I hate this I'm not having fun anymore there's still a lot of flux but the problem is that it does blows it over right away we're going in hot kind of makes sense that the mask would actually slow down the process I guess okay so it's not melted oh my god is this heated up yet oh one of them just moved for sure this is supposed to be like a quick and easy video we were like oh you know yeah what about that dead AMD CPU we got those solder mask yeah sure we'll just you know we'll put the pins back on it oh boy I think we wound it it's not great but the pins are on there I could just be some burn flux so can you see how crooked they are did you try and throw it in a socket at this point are these pins longer than the CPU though hold on a second oh my god they're longer well let's see if they even fit in the socket you know I specifically asked you if the pins were the same didn't I you can tell just looking at it Nicholas your only way out of this is for the audience to just love how much you've been messing with me for the last 45 minutes so Brandon how excited are you to find out if this works okay you have faith but the thing is sometimes you can kind of straighten them out with the socket even after resolder in them I might need to bend them a little no this one is not attached well enough crap we got to heat it up again holy just lose then actually they all seem to be on now all right I have a new and fresh concern Nikolas these pins look like they might be a little thicker well we'll see if they go in there moment of truth time now boys and girls I don't know if I actually want to know we're in the hunt quick get another one let's fake it we never actually do that guys no signal detected those fast spinning fans are the that is not a good sign Johanna grab a different CPU and let's make sure the bench actually works wait this is an X 370 Pro has it been BIOS flashed back alas so we're gonna put and actually out-of-the-box compatible motherboard on the bench so crosshair something just get out I'm in a hurry this is known as a speed motherboard swap ok we're going with the broken one we're going straight for the Hail Mary here oh they're moving well that was either a good sound or a bad sound no it's not making it okay trying the known good CPU just to make sure there's not something else wrong with our configuration here this is an x5 70 board right for 70 is not compatible out of the box I gotta keep track of which crosshair number corresponds to which damn chipset okay hey since take notes just call it the crosshair King X 570 okay and if you do another one call the crosshair X 570 - - there you're welcome is this an X 570 motherboard I want you to read it off the motherboard itself it's in there I saw it's fine hope we have to take another we have to hit it with this so like what do I do it doesn't melt I'm fine honestly if this thing managed to survive being heated up and cooled down this many times like this it's you know kudos to AMD you know you get a bunch it no a different pin just came off we're back where we started three missing pins nope one more time and it blew one of them over show me the snap into place you horrible piece of garbage no but the ones next to the mark melted nothing is melted like is this the right temperature I'm going up [Music] now you piece of garbage every one of these pins should be melted right now and they're not cranking it to 450 just blow that didn't do it I don't know what can nope never mind this just pulled the same thing right off we actually managed to reattach the three pins that we were trying to last time but the pin that I was using to check and see if it was melted that one did not reflow so we need to put a new pin there now doing more flux and it's dying Palance all that one solid the one we just tried to attach a solid I think all the pins are on this one's bent in a bit of a funny angle but maybe we can just give it a little well let's get a heatsink on it how how how how how yep lost a pin again putting this back one teeny billionth time okay the army that's hilarious all the pins just snapped into place I'm pretty sure it refloat this time I think it's the camera operators I think they will us to fail okay you might as well roll on this gave it one more crack without the camera rolling so I get this light out of my way and actually see what the heck I'm doing and as far as I can tell all now five of the pins that we've had to either reattach in the first place or reattach after knocking them off are solid and more importantly I actually got that snapping effect and everything is lined up real nice now just goes to show you soon as you turn on a camera it's in why does it just say eh' MD 50 I don't care about AMD's 50th anniversary right now I just want to know what's going on with this computer [Music] No yes okay I can't even believe it it's all dried fish risin 7 you had no reason to have faith Brandon risin 7 3700 x8 core processor 64 gigs of RAM I'm gonna put two more sticks in I'm afraid to feel too good about this yet show me all four sticks yes there it is Oh first let's do it live okay there's the HDMI cable okay you can tell it's the right one because the TV's gonna turn off you see that I am shutting down this system I am pulling it off because there's always some jackass in the comments that's like a fake a pre-recorded yeah carefully well those pins are a little bent it's kind of hard to take out and there's a lot of flux in that socket now so that's pretty cool but there it is that's the one you know how you can tell cuz there's a bunch of pins that are taller than the other ones at the back so guys you might be thinking at this point gee Linus that looked like a lot of work and frustration why would you want to do this well reason one I think is pretty obvious out of necessity maybe like Ethan you accidentally dropped your new CPU while you were attempting to install it another could be to save a buck maybe like us you found a sweet deal on an upgrade but it's got some pins that are bent or broken or maybe you just want to learn a new skill if RPGs have taught me anything more skills even if you have no idea what they're for yet are always worth putting at least a few points into that was about the most stressed out I've been since probably the last time I did an AMD CPU pin repair video which coincidentally is still running that CPU because it actually had a broken pin and all we did was jam a little piece of metal or pin into the socket and then put it on there so I couldn't like take the CPU off because it would unfix it so NCIX didn't want it back and I was like oh okay my parents need an upgrade that system still runs to this day I had a bunch of haters on that video to be like oh it's a bad way to fix it it won't last oh it sure did just like my segues will last forever to our sponsor Squarespace

just traded a bunch of merch for a 3,700 X yay go - so guys if you like this kind of DIY nonsense you might also enjoy our finale of our red camera water cooling series go check that out and subscribe to see that when it comes out wait that one's not out yet by the time this comes out I suspect it will be so go check it out and subscribe anyway honestly I feel like I earned this yeah between the hours I put into it and the merch that I paid for it I don't even feel that I'm keeping it

I took a FX 8350 to a jewelers once because of bent pins, I had a brainfart and thought he would have the tools for the job so gave it a try, he even let me have a go, it worked and I gave him £10 for 10 mins work, he said no keep it but I insisted.

[u/Narfhole]

This is actually good LTT content.

[u/Kaziglu_Bey]

I hope AMD stays with these pins on consumer CPU's for as long as practically possible. I used to see a couple of home builders every month that trashed their Intel LGA sockets beyond salvation, while I've never seen an AMD CPU that couldn't be fixed within a serviceable time frame. Time is money especially if it takes up time on a tricked out workbench, which more than the slightest LGA mishap is likely to require.

[u/slaktomafro]

😖 just thinking about that

[u/prouska19]

very surprising that it still worked after they out it back in

[u/Sacco_Belmonte]

I think he needed less air on his gun and avoid using that stupid template. It should be an easy job with a cheap microscope. Components go in place themselves due to surface tension.

[u/no112358]

He didn't use any solder, only flux,

he didn't actually clean the new pins,

that template is stupid,

and they complicated it to hell and back.

[u/DeadMan3000]

I've never really understand why we still use pins of any sort. Surely we could just have small sprungs ball contacts on both the CPU and socket that make contact? I am guessing it's a manufacturing cost issue.
