now you guys might have seen the video we did recently where we disassembled an
8k red camera with the intention of water cooling it and um
well we do intend to do that eventually
but uh you know baby steps right so the first step is making
any water block and that is exactly what we have in store for you
guys today the first ever Linus media
group water block well except those ones they made in
scrap air wars
mack weldon wants you to be more comfortable so if you don't love your
first pair of underwear you can keep it and get a full refund with their try on
guarantee use code tech tips 20 to get 20 off at the link below so we have we
have no we have no script and no structure for this whatsoever then is
that do i understand this correctly yes okay
so step one uh drawing inspiration you
want to come over here david we actually did a video a little while ago where we
bought a bunch of cheap water blocks off like aliexpress
and um some of them actually were so simple that we looked at them
went well we could do that with like
you know half an hour in solidworks and then
you know a couple hours of cnc time and that's exactly what we did pretty much
yeah so this right here is even simpler than
what we did it's kind of smart how they did it
and like uh it's really smart how cheap it is to make this so if we look this is
just acrylic and it would just be like six holes
you're done so six holes and then you tap two
g1 quarter threads and bippity boppity finished okay
and then they don't even bother with doing anything besides holes in the
copper because machining copper is a huge pain in the butt
so they just have another piece of acrylic that's the right size for this o-ring and don't even bother with
anything on the inside either wow
this is like actually less than a dollar worth of
materials pretty much yeah and so we kind of took some inspiration
from that but it's it's too like easy even for us like
because we're going to need to figure out how to properly machine copper to do
some of the stuff we're doing later right so what have we done for okay so this is
the other end of the spectrum yeah this is like
pretty good where would you say that lands so by
contrast this is a much more advanced design so starting with the base it
requires machining on both the top and
bottom so you can see they've countersunk the holes for these screws
right here so that you're not going to even on a large died CPU you're not
going to just have like screw raising the block away from it so it
can't transfer heat and then it's actually got also much much finer work
than we see on our very very basic just piece of copper
here with these little fine fins that kind of guide the fluid as it goes
across where the CPU die would be underneath and then away
furthermore it's got a metal mid plate so this is to
add rigidity and allow for mounting flexibility across various sockets and
then it's got again double-sided machining work on the top here that not
only just sort of allows it to be attached to the base but actually has
guides for the fluid flow to help make it more efficient we're not really
aspiring to this at this point are we no we're kind of getting half the way there
so they do have the o-ring groove and
those are actually really hard to machine because you need super high tolerances
you mean in the groove low tolerances yes you need super low
tolerances within this groove because otherwise i mean
to put some perspective on how important that is if your o-ring doesn't fit
correctly you leak water on your
you know thousand dollar computer or thirty thousand dollar camera as it were
we aren't going to be able to get these kind of fins unfortunately could we have
done any kind of fins we could have potentially got like so the bit that we
used this is our actual block here it was an eighth of an inch and that's
getting it in like this groove right here is just a
bit over an eighth of an inch got it so that's kind of like we could have like
two fins we do have finer bits but running them in copper it isn't really
working at the moment got it so i don't know i'm actually
really stoked that we can just simply machine copper i wasn't expecting us to
get this far i was thinking that we would start this
and the bit would get like halfway in and then gum up and explode like we
already have three more in the mail because i thought that we're just going to ruin a bunch so it might be
surprising but this is a huge success for us okay
a flat piece of copper with an o-ring in it
do you want a metal like is it here
thank you okay so have you tried this yet no
so we have a couple more things that we need to do we need to tap the holes in
here okay and in here so that the fittings go in
and the bolt can go down and secure the
whole thing together okay and then we're pretty much good to go okay so uh pitter
patter let's get at her then yeah which one do you want to go at
i want to do the plexi first because that seems a lot easier to replace if i
bung it up this is really ugly acrylic that's just the machining marks there we
could why did we machine the top of it to make sure that it's nice and flat
when you get a piece of acrylic you don't necessarily know so we can get
some sandpaper and make it a bit better okay but we aren't are we
well we are a few leagues
so here we go friends oh crap i'm not putting enough pressure it's kind of
hard oh geez okay oh i am shredding this
okay i need i just needed more pressure and the great news is that this is just
the first one yeah oh we're getting pretty close yeah
actually really close we were going to go into the table if we went another half turn how straight did we go
actually not bad
oh why are you doing that so
again yeah number two tom petty was wrong
the starting is the hardest part can i take this off yeah yeah take it
off oh yeah see this side's much worse
but we can probably work with that right yeah should be fine just flip it over
um we need some fluid coming straight really
definitely not trying to ow i just poked myself in the hand why don't you just
ask for better tools instead of just making me use crappy ones
i don't think you need that okay let's put it on the table all right okay like
every every half turn or so you should go back and break the chip
that's probably good
all right times three more yep that was a good idea lubing it i
take back what i said before look at that it's like a threaded hole
and everything up in this biz like trying to make this
with an angle grinder would have been a much more interesting video
or the sawzall wasn't that like your entire like second
day of work like through that heatsink everyone got so
annoyed it was so loud right beside the editing right outside
the editing deck so now we have to do what's
kind of the make or break for this so we've got this o-ring here it's um
eighth inch yep oh my god it's like not a continuous
piece no
in fact didn't Jake show both of us a site where you can just order any o-ring
you want at any size you want why the hell did we do this
because for a lot of the custom stuff that we're going to have to do later for
like the reds and crab we're going to have to be able to make our own o-rings
this is like way smaller than the groove that is not a tight fit oh it's it's not
supposed to be a tight fit just let's just think about this one for a second
yeah yeah you mush it down a bit but not that much
oh this is the actual specification we have the parker o-ring handbook you go
in there and you're like parker over yes it's like the bible for like
engineers and stuff all right all right all right all right so what are we gonna
do like like at the you know the fair where they take the special glue and
they stick the two pieces of rope together in the water oh look one piece
of rope it's cyanoacrylate it's amazing yep
really yep i'm so unhappy right now
that's really what we're using oh my god that's actually what we're doing yep
what really it's cyanoacrylate
i hate you all right here's your mark smart guy
please don't slice my hand is this really a recommended way to do
this you know what let's just see what happens
okay you ever gotten the stuff on your hands before yes i have please don't
yeah it's a really bad time yeah i know please don't yeah that's good that's
good less is more well less is less but less is good
is what i was trying to say oh wow it's not that close it's pretty bad well in
fairness to me i think the whole thing's a little short anyway so we might as
well just put it in there and see what happens oh
actually no it's probably fine okay so i can just put it together now no no no no
we need some petroleum just this this makes another appearance we need to get
rid of this garbage this is the worst petroleum jelly i've ever encountered
you're responsible for this oh we got to grease up our o-ring yeah okay it's
disgusting it's like chunky i like my petroleum jelly like i like my
peanut butter smooth okay
so that's it um which uh which screws are we using
those ones oh it's the wrong way oh it matters no no i know i did that on
purpose but there's no way the o-rings for the fittings are to seal on the
other side when i took those chunks oh yeah so we're just gambling here
i mean theoretically there's nothing like really climactic what's happening
right now please catch we're good okay hit me with another one
two so that's it moment of truth
yeah find out if it leaks
um dot in the center and then little dots on either
corner all right so yeah no why would we why would we drain the loop all we have to do we're going to open up a side here
and we're above the water level in the reservoir so what should happen
is we should start to draw in air is this open enough
that's totally open so as long as we don't lift this up too high see how the
water level rises there we go then we can have the tops of
our tubes drained this is it moment of truth
that's only a bit wait did we even thread this correctly well maybe we have
to go from the other side we did tap it down from the other side
oh that's gonna suck
all right let's put it on the other way we'll do it the way you want this did
actually come together pretty smoothly
we're not done yet we can't be too happy at this moment
oh this gives us a better look at the o-ring actually so you can see where we
mushed it together there that might not leak so you were right the
direction you thread it definitely matters either that or we didn't go through enough so that goes on there
oh yeah that does that's not that's not before that yeah we could just zip tie
it we could just not no no no no no this is a very well worn
okay you know what yes we can just not just a sec
no why would we why do we drain the loop okay this one goes on we can use this one
well yeah that's also a good plan yeah that was the problem with these fittings
so what's gonna happen now is i'm gonna move this down here
and uh it's gonna fill with water
you can actually see some water in it oh no it's completely full of water now
okay and then we can seal up the top of our reservoir here where'd that fitting
go i feel so bad for the people out there that like know what they're doing
this must be like watching monkeys like just when i hit this button we're gonna
find out if it leaks or not
seems to be fine now it could take a while for us to find out if it's gonna
leak but yes it actually
does seem to be fine how about that
just can't stop looking at it i'm just like so sure it's gonna leak why
well you saw that o-ring yes
look at it right now do you not trust parker i mean is this like is this like
restaurants like working at a restaurant where as soon as you do that you'd never
eat the food like as soon as you like make anything you just like never like
you just never drive in a car again like knowing what the tolerances are like
well cars are pretty good it's airplanes that really scare me their safety factor
is like under 10 like normally on a car you do at least 50 and they're just like
nope any extra weight is a bad thing so now what we just give her
all right so well let's let's for say what we need to do yeah but it's gonna
take a while before we're gonna know so we should probably give her
okay sure all right we're giving her boom all right so here comes the heat
max of 82 degrees to beat the aliexpress
and that's this one that we i think is even more cheaply constructed
than ours is that correct um ek is 64.
so we're already up to 78. so
oh wow really oh on the hottest corner on the hottest
core yes oh also we never machined the bottom
which they clearly did yeah have you seen what swift does with their skeeved
thing where basically it like slices into the metal and then folds up a slice
no it it's amazing can we get one of those
machines nope no close all the tabs done
and we're at 83 degrees damn it
84. actually it settled back into 81. i wonder if that was just for me like like
pushing on it i mean obviously you can't design a product to have the user just
like hold it down well but we can just tighten these a bit more
hey victory 80 degrees yay
we beat aliexpress
for a higher cost so there are some other factors to
consider here too um like whether or not our base
was made convex oops or concave by the uh mounting
pressure of putting the top down on our o-ring that might be part of the reason
why these guys went with this plastic plate like we
actually don't know why they went with an acrylic plate oh wow they didn't even take the
freaking who leaves like the paper on a
finished good that they shipped to the customer so what was what was this one's result
or did we not test that one we didn't test this one okay we just did the ek i
mean it doesn't really matter we got our asses kicked by everything
yeah but but
the really positive takeaway here is that
it really is not leaking so
what that means for our future projects is that given that we're not going to be
trying to cool a 7820x freaking 8-core CPU
yeah we're going to be like we're in good shape yeah
we can make water blocks to fit on anything now they won't be the best
water blocks no they won't i really want to do the network switch yeah network
network switch next and then
a challenge yes like we only need to beat this
that's going to be this sucks look at it it's terrible it's terrible
okay i'm feeling good yeah
