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 his shiny new ryzen 7 3700x
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 straightened other times
you'll get uh 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 pin 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 traded 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 grizzlies
oh geez i hope not but thermal grizzlies conductor not
liquid metal tim offers maximum cooling performance check it out and keep things
cool at the link in the video description
before we start let's talk about the tools we're going to need a magnifying
light 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 two so that it's
illuminated from two different angles would be freaking fantastic
next you're going to need a hot air solder stick can you stay please
stay good boy
next up you'll need a hot air solder or smd rework 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 a prime item so
we're just gonna yellow 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 going
to need some solder masks these are available cheaply on sites like
aliexpress or ebay the one we're going to need in particular is the .65
millimeter pitch one because that matches the pin arrangement of our CPU
as you can imagine you're not going to 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
what donor
what the it's not a big deal the thing's already dead
you know what screw it i'm going to embrace it
bring in the donut
our first order of business is to harvest some good pins so we're going to
set our station to somewhere between 300 and 350 degrees celsius
here's a hot tip by the way hey e 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 no okay i swear to god if these don't melt
oh well we got one
blue
there's one there's another one
all right
there's another one right all right we getting the hang of this boys
the last thing you want to do while you're at this is pull too hard because 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 ah 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 LTT Store.com
i'm going to be the next billy mays hey it's lions sebastian here with extra
heavy duty alcan foil it slices it dices oh my god my fingers
at this point we strongly recommend practicing reattaching pins to your
donor CPU before
all right all right all right enough we strongly recommend reattaching them
to your donor CPU until you're
comfortable with the whole process now i don't have time for that somebody
ordered some tech tips on ubereats and uh
these babies ain't gonna deliver themselves so we're going straight to our new CPU
hoping for the best here so we're just going to go ahead and pop that on make
sure that that is in fact actually 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 tweezers it's going to be hard to get a good grip on those dang it
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's the
hardest one come on
yes now i just gotta find where that uh
first pin fell how hot's the CPU
ah okay yeah it's oh it's in there ow ah
dang it brandon can you see this can you ow 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 20 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 going to 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 is 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 box
that's going to 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 wanna i just wanna 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
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 we've got like a flux booger on there all right this is
not easier um okay i think that's where that one goes
my certainty level is very low yeah i kind of 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 should go watch that other guy's guide on this he does it better than i do
okay i'm doing this right handed i give up i can't i can't show you guys what
i'm doing because i need to do this with my with 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 going to come straight down on it it's going to snap into place
why do i doubt that hold on hard bail hard bail i'm bailing
okay none of those are attached okay new plan
we are putting the we're putting all the pins on and slipping the solder mask
over top because i don't think these pads actually slip through here they do
not well that's good oh my god we can just
put the pins in the solder mask nicholas
bad instructions holy crap that's how you're supposed to
do it this is so much easier so all we're
going to 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 gonna let it cool down we're
gonna pull the mask off and see if the solder soldered
i'm gonna 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 no 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 no it 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 masks yeah sure we'll just you know we'll put the pins back on it
oh boy i think we ruined it it's not great
but the pins are on there that could just be some burn flux so can
you see how crooked they are did we try and throw it in a socket at this point
are these pans longer than this 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 i have faith you have faith but the thing is
sometimes you can kind of straighten them out with the socket even after re-soldering
them i might need to bend them a little no
this one is not attached well enough crap we gotta heat it up again
holy sh just loosen actually they all seem to be on now
all right i have a new and fresh concern nicholas
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 or not 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 do you want to grab a
different CPU and let's make sure the bench actually works wait this is an
x370 pro
has it been BIOS flashed
so we're gonna put an actually out of the box compatible motherboard on the
bench so cross hair something or just get out i'm in a hurry
this is known as a speed motherboard swap
okay we're going with the broken one we're going straight for the hail mary
here feels like i'm having oh shh
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 x570 board right
470 is not compatible out of the box necklace
no
i can't keep track of which crosshair number corresponds to which damn chipset
okay ASUS take notes just call it the crosshair
x570 okay and if you do another one call the
crosshair x570-2
there you're welcome is this an x570 motherboard
i want you to read it off the motherboard itself it's in there i saw it it's fine okay 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 of
no come on
a different pin just came off we're back where we started
three missing pins do you want to take a break from this 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 them aren't melted
nothing is melted like is this the right temperature
i'm going up
melt you piece of garbage every one of these pins should be melted right now
and they're not i'm cranking it to 450.
just flow that didn't do it i don't know what can
nope never mind this just pulled the 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 that one's solid that one's solid
the one we just tried to attach is solid i think all the pins are on this one's
bent at 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
lost a pin again putting this back on for the new billionth time
okay brb that's hilarious all the pins just
snapped into place i'm pretty sure it reflowed 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 as soon as you turn on a camera
it's in why does it just say AMD 50. i don't
care about AMD's 50th anniversary right now i just want to know what's going on with this computer
what was that no way
yes
okay
i can't even believe it it's all dry at fifth rising seven you
had no reason to have faith brandon ryzen 7 3700x a 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 where is it
oh yes there it is oh
it works let's do it live okay
there's the HDMI cable okay you can tell it's the right one because the tv is
going to 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 uh uh fake uh pre-recorded
yeah carefully oh 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 because 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 um 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
it sure did just like my segways will last forever to our sponsor squarespace

this CPU because i just traded a bunch of merch for a 3700x
yay go Linus so guys if you like this kind of diy

go check that out and subscribe to see that when it comes out wait that one's
not 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 yeah between the
hours i put into it and the merch that i paid for it i don't even feel bad i'm
keeping it
