We Built a CPU Water Cooler! #Helpful Post

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 well we do intend

to do that eventually but 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

except those ones they main scrapped

yours

comfortable so if you don't love your

first pair of underwear you can keep it

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 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 some of them

actually are were so simple that we

looked at them and 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 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 to G 1/4 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 countered

the holes for these screws right here so

that you're not gonna 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

firm mountains ability 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 group because

otherwise I mean to put some perspective

on how important that is if your own

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 things

unfortunately could we have done any

kind of fins I 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 so I don't know

I'm actually really stoked that we can

just simply a machine copper

I wasn't expecting us to get this far I

was thinking that we would start this

and the fit would get like half way 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 medal like

is it here 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

peter-patter let's get out of it yeah

which one do you want to go up I want to

do the plexi first because that seems a

lot easier to replace if I hung 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't come okay

but we aren't are we well we are if it

leaves so here we go friends oh crap

I'm not putting enough pressure it's

kind of hard you okay oh I am shredding

this okay and you 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 gonna 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 now oh yeah see this sides much

worse but we can probably work with that

right yeah

should be fine flip it over we need some

fluid go straight really definitely not

trying it wow 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

okay let's put it on the table okay like

every every half Turner so go back and

break that chip that's probably good all

right times three more no 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 Freud you think

everyone got so annoyed it was so loud

outside so now we have to do what's kind

of the make or break for this so we've

got this over in here it's um a pinch

yep oh my god it's like natto continuous

piece no in fact didn't Jake show both

of us a site where you can just order

any o-ring you want it any size you want

why the hell did we do this because for

a lot of the custom stuff we're gonna

have to do later for like the red thing

crap 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 you

mush it down a bit but not that much oh

this is the actual specification we have

the Parker oring handbook you go in

there and you're like Parker oh yes it's

like the Bible for like opening

engineer's and stuff like so what are we

gonna do like they get the you know the

fair where they take the special glue

and they stick the two pieces of rope

together and the like 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 it 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 that's a really bad time

yeah I know please don't

yeah that's good that's good less is

more but less is less but less is good

is what I was trying to say oh wow it's

not that close pretty bad well in

fairness to me I think the whole thing

is 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 no no no

we need some petroleum do this this

makes another appearance we need to get

rid of this garbage this is a source

petroleum jelly I've ever encountered

you're responsible for this oh we got a

grease up our overhang 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 which

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

gonna seal on the other side when I took

those chunks oh yeah so weird 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

give me with another one too so that's

it

moment of truth yeah find out if it

leaks dot in the center and then little

dots on either corner all right so yeah

I know why would we why would we drain

the loop all we have to do we're gonna

open up a side here and we're above the

water level in the reservoir so what

should happen cuz we should start to

draw an air this open that's all 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

ah there's only bit wait who even thread

this correctly maybe we have to go from

the other side we didn't tap it down

from the other side oh that's gonna suck

alright 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 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 yeah we could

just zip tie it good just not no no no

no this is a very well worn okay you

know what yes we can just not just a

second okay this one goes on we can use

this one oh 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 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 it

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

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've just like net like you'd

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 percent like normally on a

car you do at least 50 and they're just

like nope any extra weights a bad thing

so now what we just give her alright so

well let's let's for say what we need to

be about 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 think is even more cheaply

constructed than ours so correct netk

is 64 so we're already up to 78 so oh

wow really well on the hottest court on

the hardest core yes

oh also we never machined the bottom

which they did yeah have you seen what

Swift tech does with their skeeved thing

or basically it like slices into the

metal and then folds up a slice no yeah

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 like

whether or not our base was made convex

oops

or concave by the 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 fricking who leaves like

the paper on a finished good that they

ship to the customer so what was what

was this ones a 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 78 20x freaking 8 core

CPU yeah we're gonna 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

never assume network switch next and

then a challenge next look we only need

to be this sucks look at it it's

terrible it's terrible okay I'm feeling

good yeah LG's hashtag scale-up contest
