for years now I've dreamed of water cooling my gaming PC with my pool and
today that dream becomes a reality
it's heavy oh no he's drowning obviously that's not
how we're gonna do it though this pool was designed from the ground up to act
as a giant thermal mass and heat sink for the space inside all we have to do
is figure out how to get the heat from there into here well it stinks which is
no mean feat like the Segway to our sponsor whatever I'm wet signal RGB
skytech gaming Intel and Signal RGB have come together to give away this Diablo 4
inspired gaming PC the swirling potions inside the chest react to your health
and Mana in real time and all you've got to do is click the link in the
description to learn more and enter the giveaway today the original plan was to
take these tubes that run to the server room and instead of running them to this
car radiator connect them to in-ground tubes that would run to the pool
unfortunately contractors being contractors there were supposed to be
four lines buried two for this two for
the solar panels and we only ended up with two so
that's only enough for the solar and we need a new plan for the server room one
option we considered is to keep doing what we're doing but better Plumbing hot
water from the server out to a radiator and pumping it back inside the issue is
not on a hot day like today that ends up
working against the air conditioning in the house heating the room and I don't
want something that I have to micromanage or set up a bunch of automations for I want this to be set
and forget that's where the pool shed comes in remember when I use that
high-tech Gizmo to find PVC piping that was buried in my backyard well that runs
from the server room to right here we have since capped these and pressure
tested them meaning they are ready to carry water meaning all we had to do was
trench from the pool house to this box where we can connect to the lines that
are running all throughout the bottom of the pool
unlimited cooling capacity
look at it all hey Don't splash my shoes oh sorry only one small problem I have
to get the water from here
over to where the pool Loop comes out here and from my computers which are
over here to these pipes way over in the corner
here fortunately I have a watertight plan for that or
more like four of them an increasing jankiness how much do you know about
Plumbing I watched four videos yesterday on YouTube
because you asked for this to be done like professional plumbers we have a
bunch of PEX tubing here which we can use to run up around to the server that
should be pretty simple getting all of it adapted to each other
might not be so simple you know how you said that you wanted this to be done
properly and I said we would have to buy specialized tools and all of the stuff
and it would be expensive oh God do you want to know how much all of the
specialized tools and the bits cost how much 950 thanks for your approval
what you said 300 yesterday I'm in 300
for the crimper and the crimps did you really buy another pack of Teflon tape
no that's from last time the good news is we have way more than we need because
it all comes in like 250 foot lengths so we can do this many
times we should find out which one of these is
uncapped uncapped yeah one of them doesn't have a
cap on it and is filled with water and it looks really nasty three and four are
labeled not so much one two and five you
know what how about this I go on the other end and I just blow on them and
you watch for the water to move wow that was easy oh and that water is
draining now uh-oh I sincerely hope that that water is not draining into this
room uh no the answer is no okay
everything is fine come on
come on we go oh they're all disgusting great
these caps worked so well and oh wow
this is gonna suck
oh
not sure if that did anything I guess that's whatever Linus just blew into
that one I think I heard water's splooshing oh but I think I have a
camera operator yeah good job Glenn so which one did you just blow into what do
you mean by just I blew into two first one then another one yeah it doesn't
really matter they both spurted really gross smelling water all
over the place so
one three one perfect got it
there
yep we we know we have fun here we need
to do something about that water we purge it with that water in fact these
are threaded do we have anything that goes into them
do we have anything that goes into them we're planning on using them for the
whole video I own more plumbing supplies than I
would have ever cared to own perfect okay we're going with number three all
right you hooked up yep uh you know what hold on
that's Mains pressure this particular hose bib is running like City pressure
okay it's it's pre the down pressure
whatever thing for household use
so it goes as long as when I turn this on do you want to go outside
let me know on it how about when I turn this on do you want to go outside I've
already smelled how bad it is you can you can do that
oh no it's not gonna go in the pool how hard are you expecting this to go oh
hi oh wow that is uh very dirty yeah it's
really gross oh oh oh it just hit me oh
that is dank
no I'm still seeing bits of crab coming out of it
are you giving it full pressure
we probably should have added a filter into this somewhere that would have been
smart that'll be the final deployment maybe go ahead and cut and we'll just
let it run for a few minutes and then uh yeah what I'm currently trying to figure
out is how we connect from those hoses
to the server itself where I guess the computer my plan was to use this guy
right here and with the magic of JB Weld
it stays there forever oh okay well that works but that still doesn't answer the
question of what we're running on this oh that goes to the packs oh I see and
we just crimp it onto here yep Alex I noticed you brought Flex tape
you're not really planning on using this are you we're not planning
on using it okay how many of these do you want two okay uh I can do that oh
God I don't remember the last time I used an epoxy tube that wasn't completely crusted over so I
pushed a little harder than I needed to this one's brand new you're gonna try to
move pretty fast here
wow she's setting already uh yep that's it that's all the time you
get holy schnikes and it's jelly well that's
good that's as advertised do you happen to have a stepladder step ladder I do
are you sure you wouldn't rather have my biological ladder what
or as I call him step laddie
do you want to climb on him we now need to make a Pex tubing tutorial while
doing it for the very first time step one
unwrap Luke's dad be watching this like oh looking for me that he could help
with this after I had already bought everything and the plan was completely
concrete how much did this cost 130 oh sick
it comes with the go no-go gauge so if this one goes on you're fine
if this one goes on when you like rotate it a bit it means that you have like
ovaled it cut it to length using the wonderful castrator 9000. wow that
does actually work really well for this yep everything else we've tried to use
this thing for has been kind of a disaster
insert this there we go okay can we just go
straight up suspended and then straight
across okay okay well conveniently we
can use this piece all right this goes here right
and then
theoretically that is flipping on there now we just
gotta uh more
it occurs to me that our plan today is only to hook up the one system so we
don't exactly have a payoff where we cool the whole Rack or whatever but what
we can demonstrate is that with that giant thermal Mass out there we should
be able to get better results for our CPU and our GPU temperatures of course
to prove that I have to start a stress test while we're still running on the
radiator that's just at the back of the rack here so I'm gonna do that Alex do
you want the CPU running too hit it all hit it all okay
be honest realize Linus yes we need a
pump oh shoot yeah we talked about this
before the pump is supposed to go there and it's supposed to be from Matt yeah
that that is the plan I kind of forgot about that though
we just simply cut this tube here this one's too long anyway so now Hey
look it's parallel it goes over there
to the pump then back I mean I don't
have a better idea cool I swear the final deployment of
this will be like I'm going to plan oh yeah this is
beautiful I'm quite certain that you did this correctly but the pump's in the
right direction okay
I mean after not having a pump at all surely we wouldn't make a mistake like
putting the pump facing the wrong way okay there's our anti-dibration mat and
then how does it come back into the bucket I'm going to run another PEX tube
over to here and then just soft to it
okay temporary I'm sure the plumbers out
there are cringing through their computer screens right now but while we
might be using JB Weld and we might have too many right angles in our setup
I think we're pretty close to having this functional at least which way does
the coolant flow in each of these this one goes out up this one right here
is in okay so this one right here goes net
like that that way wow that plumbing looks great hopefully none of it leaks
now uh one thing that I've learned from going to plumbing supply stores is that
you need to check the things that they give you I was supposed to have four of
these oh I have one of these and three of these for reasons it's gonna be fine
but we need to go out to like the connections outside from the water cool
in your house thing and steal a bunch of male to male things can't we steal from
these guys right here we can but then we
have water right above your server no no no no we got this look I found a bucket
okay I'm just gonna go outside and do it okay we'll see who gets this kidding first let's go he took the vice grips
you can't do that oh Jake what are you doing buddy I almost fell over it's fine
are you kidding me I'm trying to do something right now what I'm trying to
do something right now yeah too bad I'm filming a video I'm filming a video too
I'm filming a video
stop please God you animals do you want
to go let Alex know that I have these fittings now if he could just give me
the vice grips these bad boys are dripping there's
foamy water all over the floor uh it looks not too bad I don't think
there's anything oh wow the whole side of the rack is wet
I think everything's still up and running though
whoops so sadly this isn't quite what we
need because these are hose fitting to npt which means that we cannot use the
PEX tubing outside we do not have the correct connections oh cool he's out of
the way now now do you know what we can use outside because this right here
terminates an NBT right there the tubing
that we already have the soft tubing yeah the soft tubing that is really not
ideal nothing's ideal I mean there is
something that's ideal it just isn't that yeah let's do it this side should
be relatively simple just PVC glue PVC
pipe Boop
Boop you're done but no that's it that's all you do the other side well our PVC
glue is hardened
medium bodied gray that looks more like thick bodied gray is this gonna work
okay maybe a little less enthusiasm we're gonna know really soon
uh-huh okay theoretically that forms a chemical
bond that is as strong as if it was just one piece I don't know what anime has to
do with any of this but there you go it actually does seem to be on here pretty
good I think we might have gotten away with one here the connection on this
side is going to be absolutely disgusting so the plan was to Simply use
this fitting right here which goes from this tube to this tube and your set
that's all that you need but I do not have any way to go from this tube to the
soft tubing that we are now using which means that I need to use this to this
tube to this fitting
to this thing and then we're there none
of it will leak for sure one thing I didn't think of until now is that this
tube shouldn't be filled with crap but it might be
find out
goodbye smells like glycol that's good it occurs
to me that I have absolutely no idea which of these goes in and which of them
comes out but in theory it shouldn't really matter since it's just a big loop
down in the floor of the pool so if we go in from this side of this side or
this side of this side doesn't really make a difference how's it going
absolutely fantastic really yep really
yeah really uh yeah okay see now we're
getting to the truth okay really yes it's fantastic you
remember when I said that there were four plans yeah this is the fourth
you've got the adapter to the adapter to the other adapter to the more different
adapter to the hose yes uh can you crimp
this one uh not really no flex tape that that was
my plan for that you're freaking can I
make a suggestion yeah what if we just put some silicone in
first yeah that's probably a good idea
we are actually using Flex tape yeah I
thought it was just a meme it's both a meme and a product and
if it leaks here today then they're a
memeing a bunch of liars I guess well I mean you didn't really apply it very
well well but like have you seen the commercials there's like and then it
works holy crap I think we're ready to test this mess I looped around the one
that goes to the system all right so the idea is that we'll just fill the loop
and then we could just put a bucket under it and pull that off
sure connect the system and then go because that's the highest point of the
loop okay we ready sure
pump going I don't know I can't tell
give me water though yeah yeah water water go go
I'm done the pump's definitely going wait we need to go outside
we need to know what it's doing Alex can you see that from there uh yes
okay then you're on the thing uh is he gonna is it pump on I can't
I can't tell what's happening right now this one seems to be empty though and
this one's full the flex tape is somehow not leaking yet
that is truly remarkable how much tubing
is in there I don't even remember I think we have I
think we have footage of it from before hey hey here it is here it is
oh oh it's a little grungy uh it's a little grungy
it's actually oh that's a rock there's a rock there's a rock in it there's a rock
in my water cooling Loop we're gonna need a filter in this whoa
well the flex tape isn't uh working the way that it's leaking is super weird
though and this uh this fitting that I asked Alex about he said is definitely
right is definitely not right you know what though none of this prevents us
from finding out what the cooling results are like though
let's head inside I heard you have a fitting that's leaking
do you know how many fittings I have that are leaking all of them
well the Bowflex tapes are leaking and
that hose thing that I asked you about is definitely leaking that's not
supposed to spin like that yeah the only thing that I have that's leaking in here
is also the connection to the soft tubing so that seems to be a theme did
you Teflon tape backwards is that why it's leaking it could be as janky as it
looks all that matters is the results and right now in our pre-test we're
looking at 73 degrees on our CPU 53 on
our GPU I think we can beat that or at
least match it without kicking heat out into this room because it's intolerable
right now is one of the worst things we've done in a while yeah and like we very recently
did the heater core and this is definitely worse oh the heater core was
fine for those of you who are concerned about the pool equipment by the way this
is all completely weatherproofed and designed to be out in the elements so
it's fine Flex tape is great sure but it's not for this why is this still
spraying I don't know are we sure that the pump's off
yeah can I help with this I got gloves yeah I might need small hand man for
this okay do you guys ever have this happen your boss is like oh you have
half a day to plant a thing and you're like that's not enough time it's gonna go wrong and then they're like it's
going wrong why didn't you think of it it's like well
yeah we saw that coming you did think of it you just had to get
the more expensive crimp although I would have been pretty upset about
spending 500 on a Pex crimp that I'm never going to touch again do you want
to see if we have more worm drives um Jake had a good suggestion putting
two worm drives on each one we are shockingly close considering all
the janky solutions that we've tried today
we are down to about one drop every 30
seconds on the high pressure side and
what we're going to try is another Worm Drive clamp running in
the other orientation to see if we can close that off what do you think is
going to happen when buddy that set up all of your pool stuff and still needs
to come back every day or two arrives tomorrow and sees this what do
you think he's gonna think I mean hopefully he says I have the
right tool let me fix this yeah that would be an ideal solution let's hope
for that is it still leaking
no really damn Oh I thought the hose clamp wasn't
gonna fit though all right all right all right all right calm down this is gonna
work wait why isn't fernmark running anymore
whatever we got the before before I believe it was 53 and 74. on the GPU and
CPU the idea here is we're just gonna let this little bit of the top of the
loop drain into here then we can connect our fittings to the
system and we're ready to test it um that's a lot of water yeah that's
that's a lot more water than that is expecting yeah okay it's fine it's fine
okay we good I was only a bit concerned now for a second bucket trick
it's a good thing there are computers all over the place yeah
um is there a reason we're doing this or
did it just start leaking again yeah it just started doing it is this the right
kind of tubing for those fittings it might be
that would be very convenient because then we could just run these tubes up there it is
it is correct okay so this is
out which means
this one G1 quarter really not designed
for these kinds of pressures but uh hey she'll try hard I was talking to the
alpha cool CEO at uh computex and was
like yeah some of your fittings failed when we put them under the pressure of a
pump and it was like oh those are rated for about seven eight PSI what were you doing it's like uh pumped rated for 100.
he was like yeah they will fail we need to turn this on oh yeah the system has
no pump and no rad okay hold on hold on did you just turn
it on yep holy okay it turned it wasn't quite ready yet no no you're good you're
good you're good you're good okay okay hold on what's our temp set Alex be
ready to hit it okay hit it now we're at 95. let's go let's go let's go pump's on
is it on yep pump's on CPU is down
83 79 I think it's good let's give it a
second to settle in here CPU die average though looks like we are about
15 degrees lower than we started
how's our GPU well GP is going to need some time
actually no normally you would have to wait for the
loop to equalize in order to take a reading this Loop is never going to change in
temperature so whatever we're getting now is what we're getting I have the
math on how long it will take for this
Loop to saturate the pool so first of all
your pool is large enough that it will take
118 kilowatt hours to increase it by a
single degree celsius so that is the entire battery of a Model X
also if we assume no losses at all and
we run this system at full wattage it will take 9.89 days to increase it by a
single degree and there are losses there are losses big losses
heating a pool takes a ton of energy our GPU is at 38.
running a fur Mark load and she is Rock
Solid holy crap Alex you said you
thermal cameraed this not recently holy crap well wait it can't be heated up
that much from the computer hold on maybe no it's not uh yes it is it is the
hot side I mean it's only like a degree or two yeah how much that's four degrees
really that's quite a bit that doesn't make sense that makes no sense that must
be the side from the pool wait no that doesn't make any sense how hot is your
pool what the hell is happening it should be set to 30 oh no I don't know
what it's set to no that is 100 the hot side from this that's the hot side from
the server we are moving heat out of here that's a lot of heat you're going
to put a heat exchanger on this long term right
I talked Alex out of the heat exchanger we're gonna put a filter on it yeah
filter should be fine it's so stupid one thing we are going to do though is we're
going to create a manifold that mounts in the back of the rack with
um shut offs so that we can stop individual
systems but keep the whole system the main pump running
for maintenance and like quick disconnects on everything holy crap
it's working you've done a lot of stupid things and had a lot of stupid ideas
this one is actually like pretty low on the the stupid meter for me I don't know
getting a pool in the first place is pretty dumb yeah yeah well but if you
have one there's actually public pools in Europe that are using this exact
concept I don't know if I came up with it first
probably not but real actual public
infrastructure is built like this in the medium term until we have all these
systems built water cooled and ready to be connected to the system it would
probably make more sense for me to just connect to that radiator back there and
use the pool to cool the air cooled systems in the room
but it's working and also we used all the
fittings that I was planning on using to connect that radiator outside so we
can't you know we really can do though is give you this message from our
sponsor Floatplane hey it's us have you
ever wondered what it takes to make one of our videos well flowplane is a great
place for you to learn more about us from behind the scenes videos to team
member highlights to travel Vlogs and more you can see exclusive content that
you won't find anywhere else check out our most recent exclusives like this
walkthrough of the stubby screwdrivers design or this wild hot sauce challenge

to see more of us you can check it out at LMG.gt forward slash LTT Floatplane
I'll see you over there hope you guys enjoyed the chaos today I promise you
the final deployment will be very Sleek
almost as Sleek as this plug for our lgd store towels no
oh
