recent recently alex and i shot a video
assembling what is the very first
Linus media group manufactured
CPU water block now of course our
objective though in all of that was not to build a CPU water block because quite
frankly we could call up our friends at alphacool ek swift basically anyone and
they would do a much better job of it than we did no offense yeah not taken
the objective was for us to water cool a
red 8k camera but baby steps right so
this was doing something pretty normal where we could basically clone a chinese
design and then just put it on the cnc
today we kick things up a notch with this
we're gonna water cool something a little unusual our 10 gigabit 12 port
network switch from netgear that was actually the first 10 gigabit piece of
equipment that we got well not counting like network cards
like like a switch
the hot docs uses the ergodox design which keeps you comfortable typing away
for long periods of time and features qmk firmware and hot swappable key
switches check it out at the link below uh so this is it
um they don't get
their network switch anymore in the camera then yep just unplug it yep all
right well oh crap we were supposed to do the sound
test first that's kind of the whole point if you guys
it's really loud yeah this is going to be a very inexact
unscientific test here
56 decibels sure on boot up okay let's
water cool it
how much does steve pay us for all this product placement that he gets on our
channel like nothing
so the reason that network switches are
really loud and run really hot is not necessarily because the hardware inside
them it has a ton of power draw or anything like that it's because cooling
them is a real challenge most network switches even at the prosumer level are
in what's called a single u which is the
i don't know the universal unit that's where the u comes from
i'm just kidding i made all of that up for height in a rack so that means you
can only use these wimpy 40 millimeter fans
and a lot of the time you also don't have a lot of ventilation holes for
whatever reason what's funny i actually brought my own
handle because i was using this for something
before we started so i can help
oh man i just stripped that bit
that took a long time i'm gonna go get a bigger screwdriver
oh there's the one he stripped oh
bloody hell i just stripped this one too
see i just had to go in straight that's what my mom always said what i'm
actually really looking forward to this i have it's it's a funny thing because
like computers the first thing i do with them is open them up like laptops and
stuff but it's never occurred to me to open up
our 10 gig network switch is this one that's still not oh
oh there we go so up and back cool holy crap there's a
lot of stuff to cool in here what is this are they ripping us off huh is
there another port that they don't put on the front maybe they're just afraid
of having it be 13. so here's our power supply that we're definitely not going
to touch or even get close to so my intention had been to keep it 1u
mountable though oh okay yeah but then just have like
tubing out like quick connects or something and then like an external rad
okay i mean that's one option i'm not married to it though for whatever reason
in my mind i was picturing kind of like this goes on here yeah
and we just like cut two holes for tubing
and then mount a rad like right here
like full like like engine blocks showing through the top of the hood
muscle car muscle switch and then i guess if you really wanted to we could
put like some t-connectors in there so you can make it a 1u have it go out the
side so it looks like every one of these heat sinks
is hard mounted so there's screws going in from the
bottom of the pcb and this whole main board needs to come out before we're
going to be able to remove any of this now to be clear this is not as
expensive as a red camera but this is still today
what like an 800 network switch or something like that i have no clue yeah
let's be careful with it because i can't remember how much it costs either it's not cheap though i always wonder if we
could just get away with putting little copper things on here sort of like you
said but then run a heat pipe just straight across all of them if we used a
ball nose bit that was the right size we could cut a channel
right in the top of it the right size for the heat pipe yep and then just
solder it on and and then we managed to spread the heat out that way okay and
that way we've just got this big spreader that'll carry the heat
theoretically hopefully towards our cooling yeah
okay wait a minute what oh those all soldered on there's no way how
could they possibly be
that's gonna be a pain in the butt should i go get the soldering iron yeah
all right what do you think the chances are that they're soldered on and then epoxied
underneath i was just thinking oh we do have a wig how hard do you
think it is just snip those
oh ah
there easy as pie
i should have been wearing eye protection for that brandon you're wearing glasses right
yeah i think we can get in there and just give her like a little snip
you got to be kidding me oh you you're doing it you actually did it
you actually did that works so well
everybody's got eye protection on me everybody's going to be screaming so
much like they got so mad when i just like hacked off the dvi connector and
that's like a bunch of pins
that one hit over there and then landed over there this is that is so dumb what we're doing
wow yeah not bad so you got a couple challenges
these look like they're up a little high so we might end up having to kind of go
around them um also not all these holes came clear so we
might have to either pop them back out or actually desolder them properly if we
want mounting points for our block yeah your copper slab to cover it
is probably the simplest way here's our main CPU block
and then we do a short heat pipe here and a long
heat pipe here this is actually going to be pretty difficult
yeah i don't know why i wasn't thinking it would be difficult
but it's going to be quite difficult
can we can we do this where i actually here hold on hold on hold on can can we
can we pretend that i had something to do with this and i'm like oh god what
did you do okay you can do it so
how did you do that over the last week or so he created this fantastic
well i mean what would you call this
model yeah it's just like a little model so we have the switch here all the
critical measurements for our water cooling is in there and you ended up
buying new calipers for that is that right uh yeah is it the big daddy
caliper no it's the alex's calipers
and these are really fancy because they're just very repeatable and
expensive we had problems in the past where i
would measure a bunch of things and error would stack up so i guess there
were a couple problems that we had to solve here
so the first is that i was pretty concerned that having this many heat
sources on one heat pipe would cause problems
so we have this paper here that sort of solved this for us which is an investigation of thermal characteristics
on a centered wick heat pipe with double heat sources basically tells us you want
your heat sources to be as close to the condenser as possible
so our condenser is effectively this
segment of the heat pipe right here where it will be thermal epoxy to this
copper plate which is going to be water cooled and then i guess other things
jonathan from ascend ceiling contacted us uh
and we have a heck ton of o-rings like
he's just he's just been raining o-rings on us
so so we have better o-rings this time yeah and also his card stock is amazing
like look at this it's quality yeah can we get some of this no and yeah we have
new o-ring lube so basically
nothing can go wrong yeah well things can go wrong but that's what we're about
to get to the hard part though is that we have to actually machine this
so how do you machine a rounded groove
so we have a ball-nosed end mill so that's just like it's round on the
end and you just kind of kind of just like that which was this
was like surprisingly hard to get to work properly
so big shout out to cj from autodesk he
really it's going to be like half a sketchy one
because we can't go any lower than 78 000 RPM
on our cnc router so really we should be using a mil for this we should be using
a mil for this but we don't have a mill because they're expensive yes when
you're going to cut metal you need to make sure that every single time that
the tooth comes around you're actually like cutting out a chunk of metal or
it's just going to rub and it's going to burn it out really fast so since we
can't make the tool spin slower we need to run it faster
we're being safe right yep i don't want people yelling at us about our cnc
yeah do you want to plug in the air compressor yeah i'd love to we do have
actual mist cooling now so everyone that's saying you should have cooling we
already have to blanket well you can definitely see the shmoo
here so is this just getting like more and more legit every time we do a video yeah
basically this is leaking
yeah it got dropped so we're ready yep can i press go
uh
i like to feel like i'm helping and that's the tool that we have so yeah
that is not that clean looking no
no and we're done so what happened there
was the piece of copper that we're trying to cut
shifted which means that
the entire tool path that alex laid out is now offset by
about three quarters of a centimeter so
it's possible that we would have ended up with
something usable but our thermal transfer is not going to be great
i mean if it had held down we would have something here anyway
i could that's really bad for the tool and we
have to make four of them
and we're back this time with a bit of a new plan
so now we have bolted
our copper plate down to the bed
we have also made some canadian engineering repairs to our reservoir
down here it no longer leaks thanks to some hand mix epoxy and uh we have done
away with our plan to make rounded grooves because we don't have a mill we
only have a router so why don't we just let the work speak for itself instead of
telling them what's gonna happen i can press go now right um
hey hey
let's see the finished product so this is going to be the top of one of our
blocks this is going to be the top of one of our other more different blocks
this is the block we made last time which is still here again for some reason we're using the bottom of it oh
we're just reusing it yeah i mean why dull your bits when you don't have to oh
is this it yeah so this is
the moment of truth right now oh perfect it really is actually
yeah it's 0.1 of a millimeter oversized
good work i'm happy with that
um i guess we just need to clean these off and
tap them look at that it just looks so good underneath completely see-through we
didn't bother facing it this time
that should go there yeah that goes right and then we'll have the three that
go down the middle here
whoa that's a lot of copper
now you told me pro mode was gonna have the heat pipe on the bottom so that we
were like heat pipe direct touch cooling yeah are we doing that with this one no not
with this one no that's gonna be version two what do you
mean version two we need to get this done because ed's mad they don't have
a switch for their ingest crap
but just crap yeah ingest crap we don't we
don't need these videos but yeah we're going to have to redesign
this guy and alphacool is coming up with
those like the server-sized heatsinks so those are going to like go
in the side and it's going to look super legit but until then we're just going to
like have it Linus tech 2 style just like below the ingest station
do these screws go through
not quite we don't have to widen the holes in the
pcb do we are you kidding me
well it's potentially going to be the quietest and coolest switch on
like everywhere arguably a switch that doesn't power on anymore is very quiet
and very cool
ah this bit might actually be too small that went super well nope we're good
what that was it yep that's that's all we needed oh
nice
we should probably give this a little dusty here yeah
something
yeah this is pretty bad yeah it was definitely one of the worser
ideas i've ever seen like am i just going at it with this i like
legitimately straight up forget how to do it um what about this time we just
like clamp it like this yeah off the table yeah
you can just kind of get this on the side like like so and blame obama okay
there are a lot of people that were really mad last time that we didn't use the drill press to do this so it would
go down perfectly straight oh yeah that
would be smart wouldn't it yeah it really would you guys want to do that
nope nope
wait what the crap is this crap is what this hole
doesn't go all the way straight through the drill press had an issue
yeah it's good okay this is the really bad one i don't know
about that well you'll be able to tell from the bottom
oh jeez what did you just do that is that's pure carnage right there
oh god
that's a lot of acrylic on the floor
yeah uh these don't quite line up well like
do you want to tap those holes again oh they're all the way over here
oh crap okay so we're just kind of doing the
same thing as last time then yep
acrylate me extra cyano on the side
and theoretically it will seal
we're asking for a lot of tight tolerances to
line up here yep we're gonna put
that through a plastic washer
okay so that goes there then we do another plastic washer i'm
assuming um yeah
okay can we do a nut yup not me
there so i've realized something really
unfortunate where this right here screws in i
thought that it was just like nuts on the back that came up
yeah but it's actually screwed right into the chassis
yeah i don't know if these can come off oh
i can't believe that you got all these holes to mostly sort of line up
i measured it are you guys as excited as we are to see
if this thing is still gonna work i am
i'm amped assuming that we didn't kill it
it's gonna work pretty well i mean we didn't do anything that bad to it
not really we're not gonna actually power on the
switch we're just gonna power this pump and then make sure that nothing leaks
did you fart yeah but like a couple minutes ago
it's really lingering oh well i'm sorry about that
it's awkward all right well given that our system here has
passed our exhaustive three-minute uh stress test
would you say we're ready to power it on yeah
there's a light david oh it's green identifying it's green
that means 10 gig link oh yeah test
and there it goes indeed
boom okay so now what no now we we actually
get to put it together yeah i guess so okay
damn i have screen cap going so you don't need to come over here
there is one more test though it's possible that we're not making good
contact with uh anything like we actually don't know that just because
it's working that means it's working well i love that our fans just say
failure because they're not they're not plugged in question for you though yeah uh did you
get new like quieter 40 millimeter fans to replace these well i guess if it's
just open can we just stick like a 140 on top or something
yes yes we can all right
yeah so what we can do is we can take this puppy
put it on do a 140 millimeter cutout
mount the radiator to that so that nothing could slip through put
the fan on top and put a fan grill on disassemble this
and put it in and i'll get a hole in here sure cool are you gonna measure
where the hole goes yep so i think we're almost done here
um okay
speak for yourself because we need to power the pump
oh i think what we have to do is plug in
the power supply and start probing
it's in panic mode and i put it in the ammeter oh
all right well let's see if anything still works
12 volts yay wow it's a christmas friggin miracle okay
so that is
ground and 12 volt look here
so ground is the far left 12 volt is the
third theoretically orange is ground what
the black is positive 12 volt and yes Jake
it matters okay i have good news though
look what i found what in the bowls is that this is a six
pin pci express adapter see these two pins it's a six to eight pin adapter we
can use these two wires to find our 12 volt power and then splice that onto the
power connector for the pump so then as long as we get the right two
pins then we're good okay so what did i say orange was ground
black was 12 volt yup neat theoretically
when i plug in the switch it will turn on with no sparks
power leds lit
and theoretically okay more sanity check
time i have 12 volts here
oh huzzah
what a nightmare yeah now it just needs to get connected to this yeah
other than the hole in beginning this is actually surprisingly like sort
of properly done yeah like sort of properly
i mean there's no proper way to do something that's stupid yeah like i guess if we could get a
couple zip ties in there like yeah 100 pro
all right a couple LTT cable ties get that
shilling in there oh yeah um a bit
concerned about putting this on how come we have to kind of go over the tubes
and just not slice them
well but can you get your hand in there when it's like that uh yeah i have small
hands
here if you let go here i can help you align this side
we might as well well have these ones kind of come up similarly you know
okay
the best part is that like it looks so good on the inside like it's pretty like
pro like all machine and stuff and on the outside it's just like straight like ghetto like
not even the same color tubes hot rodded like
it's not very space efficient it's very
heat efficient yeah does it work faster
no it's a lot quieter yeah did you see how quiet it is i don't
think i ever actually heard it so that didn't seem like an issue to me but uh
it was like yeah it was pretty loud
it's still working temperatures are actually lower but we have a fan running
on the radiator now so that's an improvement yeah we're looking at 27 and
28 degrees compared to like 51 and 42 before it's
dead silent and let's do a quick file transfer here
here we go
i'm liking it
backblaze is an unlimited cloud backup for macs and pcs that's just six bucks a
month they've restored over 35 billion
files and they back up documents music photos videos drawings projects pretty
much anything and you can restore your files from anywhere you can directly
download them from the web or restore them by mail even their mobile app gives
you access to your files on the go and actually this is great if you do the
restore by mail option you can purchase restore via hard drive they will
overnight fedex do the drive and then after you copy everything to your new
storage device you can return the hard drive to them for a refund there's no
wonky cost structures and it is truly unlimited data backup at a fixed price
so try it out fully featured for 15 days for nothing at backblaze.com
