while I could water cool my computer with one of these when I found out that
a local data center was just throwing
away this UNIF flare inro acrc 100
server cooler I knew what had to be done
we're at 500 WS 995
Watts oh my God look at this it broke it
just says zero Watts I didn't know how complicated it was going to be something
tells me that a G14 PC water cooling
fitting isn't going to exactly just thread into this bad boy but hey that's
what friends are for right so let's drill into
this and hope that we don't screw
anything up oh just like I screwed up
that segue to our sponsor cleaning the house can be a dangerous exercise last I
used Robot Rock sa Max VR Tru which vacuums them up only one go he loves to
clean so much it even clean itself good job Rocky
wow look at this thing you can fit so
much Radiator in this bad boy but the
way that they're using it is not the way that you would expect this is a chilled
water modular air conditioning unit that's right it is intended to cool the
air in the data center rather than cooling the servers directly it's
available in either a half rack that's the one we're looking at here or a full
rack model and this older one disc continued in 2016 goes for about
$6,500 and if you look there's all kinds of indicators that this is not your
regular water cooling system for one thing it's got these drip trays all over
the place and this insulation that seems
to indicate that they are expecting this to collect a lot of condensation from
the ambient air that's because this water in Supply pipe here is meant to
take coolant that's as low as 7°
C it's an air conditioner in the sense
that it takes the hot air that is blown out of the servers on either side of it
sucks it into the back pulls it through this radiator that's got super chilly
water running through it and then blows it back out the front cooled to a
reasonable temperature where it can be recycled into those server racks next
to it the only problem is how do you get the water so cold
there are a number of solutions to that you can use good old-fashioned
Refrigeration evaporative cooling here in Canada we just Plum directly into the
nearest Glacier but realistically we
have a different goal and we're not going to worry about any of that wow D
these ever look like finger jompers the problem is our cable is just so short
but it's got all the slack yeah what are they doing causing me nothing but
Discord right now I didn't get that joke oh slack
Discord a got you what plug
into oh wow she just fires up like that
it feels great that does feel great oh
there we go hey inro okay cool check this out check this out 530 L per second
that's ply have password no oh this is
why we have to look up resetting the password I see well I guess we're going
to need to rip this off wear eye protection this time
hey see you later buddy look at that take that lockpicking
lawyer I'm kidding we have no beef great
channel in order to reset the password we're going to need this seral to usba
to USBC because modern laptops JK I use
a framework I can totally use usba let's go boom investment disclosure also back
here we've got some of the enterpris nature of this on full display we've got
Network control and redundant power
supplies press the reset button on the P back of the electrical
panel okay immediately press enter
repeatedly if necessary to display the username
prompt hey
username it's a me
Mario no no please choose a regular I'm
working on it I I think I pressed enter a lot of times and it's really confused
boom we're in the main frame is hacked
boys username what no I'm going to go
admin admin that's great enter new
administrator authentication phrase
admin Tech tips oh my God I didn't
successfully do it F do you want me to go get
shot no no it's fine it's fine it's done
bad authentication phrase I can't just put admin as the authentication phrase
hey that's a good thing I know but I I
don't care right now you know minimum 15
characters this is really
dumb oh my God
can I just set it to full speed yeah try fan speed
control man manual let's
go oh here we
go look at his
shorts 1200 l a
second and you want to replace these fans look at how I could barely hear you
talking I'm we're yelling yeah I'm right next to you 134 like almost 14 1400 L
that's the power of the whatever the this thing ISC 100 now of course it's
not going to do basically anything with the side panels off these fans are going
to pull the air from the point of least resistance which is right here so you
got to put the side panels on you want it nice and sealed up here in fact I'm
willing to bet that is one of the reasons these
panels have this foam on the inside of them we've got caps on the secondary
Supply and return right yeah so we don't got to deal with anything down there all
we've got to deal with is this Supply
and this return neither of which appears
to be plumbed with any kind of threading standard that Justin was able to
identify thankfully we've got
this I've never brazed before oh sure
that makes sense fun fact I've also never used a sawall before it's called a
sawall cuz it saws
all are you even trying this week that joke's actually from a Nicholas Cage
movie that's not even a joke that's just why it's called that what's our level of
concern about the metal shavings and the power supplies down there it's covered
it's fine so what I just go for
it hey uh Justin do you mind just putting a hand on this okay I actually
don't want your hand right there there though yeah there's good uh yeah that's
better wow I can see why burglars like
these man how did I do that so smoothly the first time okay Justin you're up
okay I'm trusting you don't take out my hands whoo whoa you should really hold
them further away no I'm good I'm good he's he's cutting away from my hands
it's fine it's not okay
all right I feel less bad you had a bit of trouble getting it started too what's
next we got some oh sick dang man that
looks professional check this out Justin
made G14 threaded endcap things that I
guess we got at Home Depot or something what do I put these on though well on
one of these but you're going to have to braze the other end on to those copper pipes first
nice what could go wrong we got some of
thiso all right so what you want to do is just it up until it starts to
discolor get it nice and even and then push the solder into the joint oh yeah
and it should look all the way around oh
yeah oh yeah no no that's good that's supposed to
happen oh God oh God oh
God I mean yeah what's it even dripping on couldn't be that harmful looks great
well very generous thank you but it
looks on there okay I may not have put quite enough
Teflon tape on this but I guess we're about to find out now it should just be
like hooking it up to a computer regularly okay you know you've done that lots of times yeah what what is this uh
this is for the pump is for these Edge these are the ones you want oh right we
should show you our pump and uh
okay sure so that kind of makes sense
because with the size of the tubing and the volume of water that you're
expecting to move through a system like this you need a ser ious pumping
solution and these things because they have no idea what your deployment is
going to look like don't have any pumping of their own wait so all that
power supply is just for those fans man
look at them though look at these fans now how Yu tastic are we expecting the
water in this thing to be they should have been serviced regularly yeah but I
think we all see the state of the inside of this with rust andw everywhere that's
the inside of this not the inside of the pipes we'll see how bad the rat is so
maybe for the start we don't actually put it through the computer we just circulate it and see what we get yeah
that sounds good are the O-rings going to seal against this kind of rough
thing oh we're going to use a 2 and2 mm
hex key which is on there already turn the float control actuator to the fully
open position and what's the fully open
position the other way oh God ah maybe
if someone hadn't gotten solder all over it oh God oh God she's turning on her
own the screwdriver is going nice open the two-way supply valve and the two-way
bypass shut off valve okay using a two and a half that's probably these guys so
that's in a weird not open or closed state so open it there you go all right
here we go pumpy let's turn our nice Prime pum Merson here there we go look
at that that's pretty clean actually yeah
right they did service it yeah you're not wrong so we'll get the air bubbles
out let it go for a little while and then hook it up to a computer freaking a
man okay now before before we do that I want to play around with these valves a
little bit cuz I don't know I it's not that I don't believe you it's just that
I think you're fullish me right now it's working so right but then I do this and
it slows to a trickle and stops okay all right all right so that was open look
we're we're learning okay we're learning together okay what's this boy what's
this boy do this is a bypass to bypass
the radiators there's no valve for the radiators but if for whatever reason you
wanted to not run through the rack okay then you can bypass it here but we
want this closed because we don't want it going straight from water in to water
out there you go yeah okay that makes
sense everything makes sense by the way it's leaking I think I understand why
nobody else wanted them but boy do I ever want them this is awesome hey look
at that magnetic Cable Management let's go LTT Store.com we're just we're just
Plumbing it up to the top of the why not
in this machine we've got a Threadripper Pro $79.95 WX this is a 96 core
processor that'll suck back I think somewhere in the neighborhood of like
freaking 400 watts or something stupid like that and and we've got an RTX 4090
one of a little it bitty cute ones a more practical deployment for us since
we're not going to have water blocked servers like this machine right here
would be to just take the hot air in the server room use that hot air to heat up
water then carry that air somewhere else and then dissipate the heat but for the
purposes of just kind of showing you guys that it does work this will do us
nicely do we have any zip ties mags oh my God that would totally
maybe work Andrew so he there you go all
right good enough magnets yeah just
let's let's see let's see let it cook oh my God cook nothing it's running at 44°
42° so we were going to go with 14900 K
originally yeah but Jake figured that the uh IHS would be too small that's not
going to tell us the full story because realistically something like this is
about the sheer volume of heat that it
can move right it's not about how well
can it deal with a concentrated heat Source like this where to your point
just the size of the Dy and the bottleneck of moving that heat away
through the IHS is going to have more of an impact than the actual like cooling
capacity of this giant unit here but in
terms of if we were to hook like half a dozen computers up to this
thing it should conceivably be able to do it
whole office water cooling anyone did I
mention already that we uh might have gotten a few of
them now that this is running the only reasonable way to Benchmark it is to I
don't know run it for an extremely long
period of time and see
if sorry I'm running 92 threads at Prime 95 this is amazing um and see if it
heats up so we've got our little temperature graph on F Mark here that's
at a solid 46 it's gone up 2° and I
haven't even turned the fans on yet I have a feeling this is just going to be
dead flat but let's go ahead we're going to get it fired up
and it's quitting time so I'll see you guys on the
tomorrow and good morning it's been about 14 hours and things are looking
real good CPU usage still 100% from Prime 95 ferm Mark's doing this weird
thing where it's kind of hitching for a long time sometimes but uh it's still
using 93 to 99% power and you can see if
I move the window around the the the render works properly
so I don't know what the heck it's doing but really that's not what we care about
we're looking at temps here we've reached a maximum of
56° which means with one system on here
we are still looking at coolant temperatures that are barely lukewarm to
the touch that is fantastic water tastic the last thing
I want to check is CPU temperatures which I'm expecting to be oh a little
higher than this WOW 40° I mean sure these Threadripper
chips yeah they kick out a lot of power but they're so big that like I was
talking about before the size of the die isn't as much of a heat transfer
bottleneck that is H that is
fantastic H what kind of power is it drawing woo 350 Watts I was out
yesterday when they were filming this crazy thing and being the person that
sourced them I had to see it for myself except I found out that lonus didn't
bother turning PBO on and I'm like the
thread rippers could draw like a th000 Watts by clicking one button in the buos
so we did that I think we start with cine yeah it's
done it's drawing 800
watts but let's try 2024 just for
reference with PBO on on this CPU it idles at 150 watts doing
nothing 450 600
600 what I don't know how optimized this is
May maybe it doesn't use like well okay I mean it's running at
4.64 GHz on every single core it's
estimating like an 8,000 Point score in
2024 for reference a 32 core second gen
Threadripper is 1,200 points this is the real test Prime 95
smallest fft is hyperthreaded this has ABX 512 which means it is going to it is
going to hurt we're at 500 wats 9 95
Watts oh my God look at this it broke it
just say zero watts in the BIOS we had set the enhancement to limit it to 90°
so once it gets to that point it kind of starts throttling down a bit not to say
that 1100 watts is really throttling down a bit
but this is just actually ridiculous
it's still not running at Peak airf flow we're definitely running into a situation where we're just limited by
the thermal transfer Block in the IHS but it's uh the inlet temperature is
20.7 De so we're not even
like above ambient really at all and the
fans are only running at it's like 900 L per second through this thing and it can
do 1400 right so this is too much I don't know how
many thread riers we' need to hook up to like make this hurt but I imagine it's a
lot in conclusion then big fans very
very effective for cooling see you at the next tech tip oh but not before I
get some help with this mess from our sponsor oh no let's suck with Rob Rock
whether it's that friend who eats with their mouth open or who don't take the
shoes off sa mxv rra can handle all the mask without ruining your friendship
