with one of these when I found out that

00:04

a local data center was just throwing

00:07

away this UNIF flare inro acrc 100

00:11

server cooler I knew what had to be done

00:14

we're at 500 WS 995

00:18

Watts oh my God look at this it broke it

00:22

just says zero Watts I didn't know how

00:25

complicated it was going to be something

00:26

tells me that a G14 PC water cooling

00:30

fitting isn't going to exactly just

00:31

thread into this bad boy but hey that's

00:34

what friends are for right so let's

00:37

drill into

00:38

this and hope that we don't screw

00:41

anything up oh just like I screwed up

00:45

that segue to our sponsor cleaning the

00:48

house can be a dangerous exercise last I

00:50

used Robot Rock sa Max VR Tru which

00:52

vacuums them up only one go he loves to

00:55

clean so much it even clean itself good

00:57

job Rocky

01:00

wow look at this thing you can fit so

01:04

much Radiator in this bad boy but the

01:07

way that they're using it is not the way

01:09

that you would expect this is a chilled

01:12

water modular air conditioning unit

01:15

that's right it is intended to cool the

01:18

air in the data center rather than

01:21

cooling the servers directly it's

01:23

available in either a half rack that's

01:25

the one we're looking at here or a full

01:27

rack model and this older one disc

01:29

continued in 2016 goes for about

01:34

$6,500 and if you look there's all kinds

01:36

of indicators that this is not your

01:39

regular water cooling system for one

01:41

thing it's got these drip trays all over

01:43

the place and this insulation that seems

01:46

to indicate that they are expecting this

01:48

to collect a lot of condensation from

01:51

the ambient air that's because this

01:54

water in Supply pipe here is meant to

01:57

take coolant that's as low as 7°

02:00

C it's an air conditioner in the sense

02:04

that it takes the hot air that is blown

02:07

out of the servers on either side of it

02:09

sucks it into the back pulls it through

02:12

this radiator that's got super chilly

02:15

water running through it and then blows

02:17

it back out the front cooled to a

02:19

reasonable temperature where it can

02:22

be recycled into those server racks next

02:26

to it the only problem is how do you get

02:28

the water so cold

02:30

there are a number of solutions to that

02:32

you can use good old-fashioned

02:33

Refrigeration evaporative cooling here

02:36

in Canada we just Plum directly into the

02:39

nearest Glacier but realistically we

02:42

have a different goal and we're not

02:43

going to worry about any of that wow D

02:45

these ever look like finger jompers the

02:47

problem is our cable is just so short

02:50

but it's got all the slack yeah what are

02:52

they doing causing me nothing but

02:54

Discord right

02:55

now I didn't get that joke oh slack

02:59

Discord a got you what plug

03:07

it feels great that does feel great oh

03:10

there we go hey inro okay cool check

05:07

bad authentication phrase I can't just

05:09

put admin as the authentication phrase

05:12

hey that's a good thing I know but I I

05:15

don't care right now you know minimum 15

05:19

characters this is really

05:24

dumb oh my God

05:30

can I just set it to full speed yeah try

05:32

fan speed

05:34

control man manual let's

05:37

go oh here we

05:41

go look at his

05:46

shorts 1200 l a

05:49

second and you want to replace these

05:52

fans look at how I could barely hear you

05:55

talking I'm we're yelling yeah I'm right

05:57

next to you 134 like almost 14 1400 L

06:01

that's the power of the whatever the

06:03

this thing ISC 100 now of course it's

06:07

not going to do basically anything with

06:09

the side panels off these fans are going

06:11

to pull the air from the point of least

06:13

resistance which is right here so you

06:15

got to put the side panels on you want

06:17

it nice and sealed up here in fact I'm

06:19

willing to bet that is one of the

06:20

reasons these

06:22

panels have this foam on the inside of

06:25

them we've got caps on the secondary

06:28

Supply and return right yeah so we don't

06:31

got to deal with anything down there all

06:33

we've got to deal with is this Supply

06:36

and this return neither of which appears

06:40

to be plumbed with any kind of threading

06:42

standard that Justin was able to

06:44

identify

06:46

thankfully we've got

06:49

this I've never brazed before oh sure

06:53

that makes sense fun fact I've also

06:55

never used a sawall before it's called a

06:58

sawall cuz it

07:00

saws

07:01

all are you even trying this week that

07:04

joke's actually from a Nicholas Cage

07:06

movie that's not even a joke that's just

07:08

why it's called that what's our level of

07:11

concern about the metal shavings and the

07:13

power supplies down there it's covered

07:15

it's fine so what I just go for

07:23

it hey uh Justin do you mind just

07:26

putting a hand on this okay I actually

07:28

don't want your hand right there there

07:29

though yeah there's good uh yeah that's

07:34

better wow I can see why burglars like

07:39

these man how did I do that so smoothly

07:42

the first time okay Justin you're up

07:45

okay I'm trusting you don't take out my

07:46

hands whoo whoa you should really hold

07:48

them further away no I'm good I'm good

07:49

he's he's cutting away from my hands

07:51

it's fine it's not okay

07:58

[Applause]

08:00

all right I feel less bad you had a bit

08:01

of trouble getting it started too what's

08:03

next we got some oh sick dang man that

08:07

looks professional check this out Justin

08:10

made G14 threaded endcap things that I

08:14

guess we got at Home Depot or something

08:15

what do I put these on though well on

08:17

one of these but you're going to have to

08:18

braze the other end on to those copper

08:20

pipes first

08:21

nice what could go wrong we got some of

08:26

thiso all right so what you want to do

08:28

is just it up until it starts to

08:30

discolor get it nice and even and then

08:33

push the solder into the joint oh yeah

08:35

and it should look all the way around oh

08:41

yeah oh yeah no no that's good that's

08:43

supposed to

08:45

happen oh God oh God oh

08:48

God I mean yeah what's it even dripping

08:51

on couldn't be that harmful looks great

08:54

well very generous thank you but it

08:58

looks on there

09:00

okay I may not have put quite enough

09:02

Teflon tape on this but I guess we're

09:03

about to find out now it should just be

09:06

like hooking it up to a computer

09:07

regularly okay you know you've done that

09:08

lots of times yeah what what is this uh

09:11

this is for the pump is for these Edge

09:13

these are the ones you want oh right we

09:16

should show you our pump and uh

09:19

okay sure so that kind of makes sense

09:22

because with the size of the tubing and

09:24

the volume of water that you're

09:26

expecting to move through a system like

09:27

this you need a ser ious pumping

09:30

solution and these things because they

09:32

have no idea what your deployment is

09:34

going to look like don't have any

09:37

pumping of their own wait so all that

09:39

power supply is just for those fans man

09:43

look at them though look at these fans

09:45

now how Yu tastic are we expecting the

09:47

water in this thing to be they should

09:50

have been serviced regularly yeah but I

09:52

think we all see the state of the inside

09:54

of this with rust andw everywhere that's

09:57

the inside of this not the inside of the

09:58

pipes we'll see how bad the rat is so

10:00

maybe for the start we don't actually

10:02

put it through the computer we just

10:03

circulate it and see what we get yeah

10:05

that sounds good are the O-rings going

10:06

to seal against this kind of rough

10:09

thing oh we're going to use a 2 and2 mm

10:12

hex key which is on there already turn

10:14

the float control actuator to the fully

10:16

open position and what's the fully open

10:20

position the other way oh God ah maybe

10:24

if someone hadn't gotten solder all over

10:26

it oh God oh God she's turning on her

10:29

own the screwdriver is going nice open

10:32

the two-way supply valve and the two-way

10:34

bypass shut off valve okay using a two

10:37

and a half that's probably these guys so

10:38

that's in a weird not open or closed

10:40

state so open it there you go all right

10:42

here we go pumpy let's turn our nice

10:43

Prime pum Merson here there we go look

10:46

at

10:47

that that's pretty clean actually yeah

10:51

right they did service it yeah you're

10:52

not wrong so we'll get the air bubbles

10:54

out let it go for a little while and

10:55

then hook it up to a computer freaking a

10:57

man okay now before before we do that I

11:00

want to play around with these valves a

11:01

little bit cuz I don't know I it's not

11:04

that I don't believe you it's just that

11:05

I think you're fullish me right now it's

11:07

working so right but then I do this and

11:10

it slows to a trickle and stops okay all

11:12

right all right so that was open look

11:14

we're we're learning okay we're learning

11:16

together okay what's this boy what's

11:19

this boy do this is a bypass to bypass

11:22

the radiators there's no valve for the

11:25

radiators but if for whatever reason you

11:27

wanted to not run through the rack

11:30

okay then you can bypass it here but we

11:32

want this closed because we don't want

11:34

it going straight from water in to water

11:37

out there you go yeah okay that makes

11:41

sense everything makes sense by the way

11:43

it's leaking I think I understand why

11:45

nobody else wanted them but boy do I

11:48

ever want them this is awesome hey look

11:51

at that magnetic Cable Management let's

11:53

go LTT store.com we're just we're just

11:56

Plumbing it up to the top of the why not

12:00

in this machine we've got a thread

12:01

Ripper Pro $79.95 WX this is a 96 core

12:06

processor that'll suck back I think

12:08

somewhere in the neighborhood of like

12:10

freaking 400 watts or something stupid

12:12

like that and and we've got an RTX 4090

12:16

one of a little it bitty cute ones a

12:18

more practical deployment for us since

12:19

we're not going to have water blocked

12:21

servers like this machine right here

12:23

would be to just take the hot air in the

12:26

server room use that hot air to heat up

12:29

water then carry that air somewhere else

12:31

and then dissipate the heat but for the

12:33

purposes of just kind of showing you

12:34

guys that it does work this will do us

12:37

nicely do we have any zip

12:40

ties mags oh my God that would totally

12:44

maybe work Andrew so he there you go all

12:47

right good enough magnets yeah just

12:50

let's let's see let's see let it cook oh

12:53

my God cook nothing it's running at 44°

12:57

42° so we were going to go with 14900 K

13:01

originally yeah but Jake figured that

13:03

the uh IHS would be too small that's not

13:05

going to tell us the full story because

13:07

realistically something like this is

13:10

about the sheer volume of heat that it

13:13

can move right it's not about how well

13:17

can it deal with a concentrated heat

13:18

Source like this where to your point

13:21

just the size of the Dy and the

13:24

bottleneck of moving that heat away

13:26

through the IHS is going to have more of

13:28

an impact than the actual like cooling

13:31

capacity of this giant unit here but in

13:35

terms of if we were to hook like half a

13:37

dozen computers up to this

13:39

thing it should conceivably be able to

13:42

do it

13:43

whole office water cooling anyone did I

13:47

mention already that we

13:49

uh might have gotten a few of

13:55

them now that this is running the only

13:57

reasonable way to Benchmark it is to I

14:01

don't know run it for an extremely long

14:04

period of time and see

14:07

if sorry I'm running 92 threads at Prime

14:10

95 this is amazing um and see if it

14:13

heats up so we've got our little

14:15

temperature graph on F Mark here that's

14:17

at a solid 46 it's gone up 2° and I

14:21

haven't even turned the fans on yet I

14:23

have a feeling this is just going to be

14:24

dead flat but let's go ahead we're going

14:27

to get it fired up

14:29

and it's quitting time so I'll see you

14:31

guys on the

14:34

tomorrow and good morning it's been

14:36

about 14 hours and things are looking

14:38

real good CPU usage still 100% from

14:41

Prime 95 ferm Mark's doing this weird

14:44

thing where it's kind of hitching for a

14:46

long time sometimes but uh it's still

14:48

using 93 to 99% power and you can see if

14:52

I move the window

14:54

around the the the render works properly

14:56

so I don't know what the heck it's doing

14:58

but really that's not what we care about

14:59

we're looking at temps here we've

15:01

reached a maximum of

15:03

56° which means with one system on here

15:06

we are still looking at coolant

15:09

temperatures that are barely lukewarm to

15:12

the touch that

15:13

is fantastic water tastic the last thing

15:17

I want to check is CPU temperatures

15:19

which I'm expecting to be oh a little

15:20

higher than this

15:22

WOW 40° I mean sure these thread Ripper

15:26

chips yeah they kick out a lot of power

15:28

but they're so big that like I was

15:30

talking about before the size of the die

15:32

isn't as much of a heat transfer

15:35

bottleneck that is H that is

15:38

fantastic H what kind of power is it

15:40

drawing woo 350 Watts I was out

15:44

yesterday when they were filming this

15:46

crazy thing and being the person that

15:48

sourced them I had to see it for myself

15:51

except I found out that lonus didn't

15:52

bother turning PBO on and I'm like the

15:55

thread rippers could draw like a th000

15:58

Watts by clicking one button in the buos

16:00

so we did that I think we start with

16:03

cine yeah it's

16:07

done it's drawing 800

16:10

watts but let's try 2024 just for

16:14

reference with PBO on on this CPU it

16:16

idles at 150 watts doing

16:19

nothing 450

16:22

600

16:23

600

16:25

what I don't know how optimized this is

16:28

May maybe it doesn't use like well okay

16:31

I mean it's running at

16:33

4.64 GHz on every single core it's

16:37

estimating like an 8,000 Point score in

16:41

2024 for reference a 32 core second gen

16:44

thread Ripper is 1,200

16:46

points this is the real test Prime 95

16:49

smallest fft is hyperthreaded this has

16:52

ABX 512 which means it is going to it is

16:56

going to hurt we're at 500 wats 9 95

17:01

Watts oh my God look at this it broke it

17:05

just say zero watts in the Bios we had

17:08

set the enhancement to limit it to 90°

17:10

so once it gets to that point it kind of

17:12

starts throttling down a bit not to say

17:15

that 1100 watts is really throttling

17:17

down a bit

17:19

but this is just actually ridiculous

17:22

it's still not running at Peak airf flow

17:24

we're definitely running into a

17:25

situation where we're just limited by

17:27

the thermal transfer Block in the

17:30

IHS but it's uh the inlet temperature is

17:34

20.7 De so we're not even

17:37

like above ambient really at all and the

17:41

fans are only running at it's like 900 L

17:44

per second through this thing and it can

17:46

do 1400 right

17:48

so this is too much I don't know how

17:51

many thread riers we' need to hook up to

17:53

like make this hurt but I imagine it's a

17:55

lot in conclusion then big fans very

17:58

very effective for cooling see you at

18:00

the next tech tip oh but not before I

18:02

get some help with this mess from our

18:04

sponsor oh no let's suck with Rob Rock

18:07

whether it's that friend who eats with

18:08

their mouth open or who don't take the

18:10

shoes off sa mxv rra can handle all the

18:13

mask without ruining your friendship

18:15

hair crumbs or mystery powder nothing is

18:19

Left Behind after a party thanks to it

18:21

hyper Force system with 10,000 pascals

18:23

of suction power it can also mff with

18:25

60° hot water and a detergent dispens

18:28

automatically at the only one deck Roo

18:30

rock is ranking number one for robotic

18:32

vacuum sales worldwide and comes with a

18:34

5-year warranty robor Rock S8 Max V

18:36

Ultra will be available on April 22nd we

18:39

have the link below if you guys enjoyed

18:41

this video why not check out the one

18:42

where we did a precursor to what this

18:44

will become in my basement setting up

18:47

radiators inside and outside to move

18:50

heat out of the building
