for our last sleeper gaming pc the goal was to build the most powerful compact
desktop rig that we could but this time our objective is a little different this
video is brought to you by sea sonic and the rig's going to be powered by their
prime platinum 1300 watt and it is gonna have everything you see here
everything you see here and
everything you see back there
yeah most of that really didn't work out but
sleeper number three margaret well she's a taskmaster
she's the biggest baddest hardest
sleeper pc that we've ever built and
did i mention that she's beautiful
floppy bigger floppy jazz floppy dvd
rewriter dvd rom what like what is this is this a zip zip disc or is it just a
cooling fan like what the hell is this um hard drive hot swappable card reader
Windows 2000 professional one to two CPU this is going to be a lot of work
yeah you know what makes it a lot harder
the chiller the chiller
and the carbon fiber tubing what why are we doing carbon fiber tubing are you
nuts the first thing we needed to do was figure out if our water chiller would
even fit inside the case we salvaged from our friends at free geek vancouver
like sure the case is massive but there's still plenty of room for error
in something like this we disassembled the chiller to find out
what was inside and then removed all the pc components in our case to make space
this is a situation yes it turns out that eyeballing things
is not quite a substitute for measuring them
well it can all fit
we can get it in but we might ruin the condenser because we have to bend these
copper tubes oh yeah that's going to be a super bad time
or we could just be like
hey kapow i'm sorry this project won't be as
advertised i think that is exactly what we're gonna do we're gonna go
overkill water cooling with the carbon fiber tubing is that not cool enough
yeah are you not entertained and then we're gonna have to i mean i
still want to revisit this yeah i think it's just a matter of finding the right
chassis like if we find an old server chassis or something
there is no reason we couldn't do that
i think the best way is to just start by building a computer in here that's air
cooled and then locating everything where we think it'll work
are you pumped oh yeah
oh those good sponsor dollars
for this build we're looking to have not just insane gaming power but also crazy
workstation power with that in mind our CPU selection was
easy the threadripper 2990x is a 32 core
64 thread beast and it gives up some gaming performance
but it utterly embarrasses even Intel's
top-end hddt chip in multi-threaded workloads
for the GPU we're going with NVIDIA's
GeForce rtx 2080 ti
i'd like to say that there's a good reason for it but it's just the best GPU
for gaming will it be enough i i think so i guess
that we could have gone for two but i don't know i wasn't really in the mood
given what we've been hearing about these it's extra important that we make
sure that everything's working before we bother water cooling it power is being
taken care of by a sea sonic prime platinum 1300 watt which admittedly is a
bit overkill for this system but on the plus side it's going to operate
in silent mode basically the entire time and like come on if seasonic offers you
a 1300 watt power supply for the project they're sponsoring
you take it so for this build i'm going to be using a dim.2
it's no real reason to use it besides just
i've had drives fail when they're down below there before and water cooling
builds and man that's a horrible time with everything installed it was time to
make sure that all our components were in working
it order pretty easy that wasn't too bad yeah i know a0
detect memory oh damn it
just a tiny bit of thermal paste i wonder if that's what was causing our
issues
okay so the the motherboard that we had before it's
just dead um so that's why we're having so many issues
and it's like it's like a week and a half since i've
been working on this because it's
bad things were happening but hopefully we're gonna
get back here and in the next day or so this will be a fully functioning pc but
i guess we'll find out in the future
all right goodbye
all right new zenith extreme
this one does not have any bent pins so
with any luck it will work just fine
code ad detect memory this is very bad dennis
our CPU might be dead we're we're gonna have to go with
something else here all right so she's working now um i
talked to it nicely like i haven't recommended and you just call it an edge
okay it's not an it's a she thank you margaret okay
i'm i'm sorry baby okay we need to put a water cooling loop in here
here's what i think why don't you use a vertical adapter bracket for the card
and have the card vertical that will give you space in behind
here to put the pump and the tubing to go up
with the loop planned out the components were removed and it was time to drill
out the rivets to make space for our water cooling
and the idea is that this right here will be the new the new power supply
holder and also will allow for us to have cable management in the back this
if it works we'll be made out of aluminum on the cnc router but
we will see in a couple seconds that it's gonna be a good time
do you have any guesses
three out of five a good one
are you talking to me yeah
now given that this is our first time cutting aluminum on our cnc
one hand will be on the emergency stop the whole time
our first piece didn't turn out perfectly but
it gave us all of the critical dimensions that we needed and let us try
out the new vice break we got from princess auto for like 60 bucks in
theory this should bend our aluminum to a nice clean 90 degrees and give
margaret a really solid chassis it's not quite as easy as a massive brake but it
does seem to be working oh
sounded good
well it did mark it up a bit but
given that that thing was like 60 bucks
i can't really complain the prototype here is a solid proof of concept
now there's just a bit of fine tuning and then we're good to make a final
version really 60 bucks for a break that manage those those uh bends yeah dang
this is problem hour with alex so you're about to watch a couple cnc
router fails and they're a lot more off camera
we tried a bunch of different things going faster going slower new bits and
it turns out it was just a double-sided tape that we got
it was not up for the task so
we're going to be switching to the most accurate tool of all
the angle grinder
we'll need to make room for the radiator reservoir and cable management this will
function just fine but gives up a lot of rigidity compared to the much thicker
piece that we were going to see and see
next the front of the case got chopped up to give the radiator more airflow and
everything was filed down so that no hands would be cut while working in
margaret with some radiator mounting holes added it was time to put the case
back together riveting is a very simple way to get two pieces of sheet metal to
stay together in a mostly permanent fashion
not quite it's not in quite right select the correct size head for the
rivet you're working with insert the rivet from the front line up the pieces
you're about to rivet and squeeze your rivet gun until it pops
repeat until your case is complete
now it's time for some painting then we can finally get on to water
cooling all right so the first coat of paint's on there
and what i'm hoping we will do today is get everything
pretty much mounted and water cooled then we'll take it all out put a second
coat of paint on now that we know that everything's in the right spot
and tomorrow we'll be done oh yeah
for the water cooling hardware alphacool hooked us up with some primo stuff to
make sure that margaret can shred or rip
all the threads that we throw at her for our CPU we're using an ice block with a
threadripper adapter then our rtx 2080 ti got an acetal water
block for that sexy stealthy
all blackened chromed look we swapped
out the connection point to make vertical mounting easier
so far so good but with the CPU and GPU in we realized that
things didn't quite line up this is gonna be really freaking
difficult it's starting to look kind of sexy though
are you turned on by computers dennis
huh now the key to getting a hard-line water
cooling loop to work its best is to have as many things line up perfectly as
possible this will make your runs a lot easier to complete with fewer fittings
that means fewer points of failure now normally even for hardline bending
the tubing is an option not with carbon fiber with that all in
mind we created a bracket then to mount our pump with some room for adjustments
after the fact there's just lots of mounting so everything's straight yeah no this is
great well this isn't straight this isn't straight either
i mean this can probably come yeah it can all be moved down a little yeah cool
yeah i think it's gonna look really cool we're not using this color cables are we
no that's just a stand-in hours are in the mail cool
so for the tubing on this build we're going with carbon fiber it's gonna be a
real big pain in the butt so carbon fiber if you like get the little
bits that come off of it on you it'll make you all itchy if you get it in your
mouth it's a really bad time if it goes into the air
also like you get in your mouth your eyes really bad ppe aside carbon fiber tubing
is pretty much like any other hardline tubing basically measure
measure again cut
sand and insert
with that completed it was time to leak test i don't have a whole lot of
confidence that this will not leak but
oh well there's our first leak and our second
leak and our third leak so we're having a couple of problems
there the main one being that there are two o-rings in a fitting and we were
only getting through the first one the second one the carbon fiber was just a
bit too sharp even after being sanded so it either just hit it or when it went
through it would just slice the o-ring to pieces and it wouldn't seal at all so
to combat that we had to replace every single inner o-ring and lubricate it
well for a nice clean insertion
with the computer leak free it was time to take everything we'd done
completely undo it take the whole thing apart and then put everything back in
permanently now one of the biggest problems with
this design is that there are a lot of things about our build that simply
cannot be accessed once it's complete without disassembling the entire water
cooling loop so it's important that we not forget anything at this stage
like this laser cut acrylic cable hiding panel it's going to look really nice but
once that's in those cables cannot come out
other cosmetic things were done at this stage too like the drive bays which were
unscrewed then epoxied into the front of the case to complete our vintage look
now with everything slapped in and the loop topped off all that's left is the
moment of truth error code 92 post error
so just so i'm clear what you've been doing for the last two days is reseating
the CPU yeah it didn't boot and then
everything that's here had to come out in order to get the CPU i just took it
out put it back in everything worked
and also like we thought that it was other issues at first oh my god
but hey the CPU is at 22 degrees now yep and it's cabled also wow you can
really feel that airflow over the vents down here they are
they are quite small for all the trials and tribulations that
have come along with this i think this may be your finest sleeper
yet
no
but margaret isn't just a pretty face
she's a powerhouse that can compute circles around her sleeper siblings in
certain workloads with zero tweaking she
got a cinebench score of 5 5001
and under full synthetic load on all 32
cores even with the sub-optimal ventilation from the front our CPU
reached a maximum temperature of 48 degrees after some tweaking we got a 4.1
gigahertz overclock on all 32 cores
netting us 6 000 points in cinebench and
a blender bmw test time of just one minute 22 seconds
to put that in context that is over four and a half times faster than a core i9
macbook pro and then even with the overclock in
longer tests margaret still didn't get any higher than 75 degrees on the CPU
and as for gaming well margaret's rtx 2080 ti means that she can absolutely
destroy games like you could fully expect to max out any aaa game at 1440p
on a 144hz monitor so that's it big thanks to alex for
sticking with this project it was an absolute nightmare because of some of
the issues with uh well how large threadripper is and
how you can kind of get inconsistent mounts in the socket sometimes and a big
thanks to seasonic for sponsoring our efforts here even if you don't need the
1300 watt beast of a unit that we put in our
system you can be confident if you choose sea sonic that your power supply
will last i tried to think of a bunch of other stuff to say about power supplies
but like isn't that the bottom line and they've got a 12-year warranty to back
