Can't Believe This Worked!!! - Concrete Cooled PC #Helpful Post

now whether it's whiskey orange juice or

Mountain Dew I guarantee you if it's in

fluid form somebody somewhere has filled

up a loop with it cooled their computer

and posted their results online so given

how done to death this concept is I

really never thought that we'd end up

exploring the whole like weird or wacky

exotic coolants concept that is until I

read a comment from one of our viewers

your leg oerstadt who suggested that we

try using concrete now hold on I know

what you guys are thinking but based on

some of our preliminary testing I have

reason to believe that this may actually

work over the last couple of days

alex has put together all the materials

that we're going to need to build what I

believe is going to be the world's first

concrete cooled gaming PC and this video

is brought to you by huni huni is the

free browser extension that helps you

save money at popular sites like oh I

don't know Amazon eBay and more by

finding you the best coupon codes so go

over to join honeycomb slash LTT and get

it now

all right so the first thing we're gonna

need is some hardware so we gathered up

the parts for a pretty sweet modern

gaming PC here we've got ourselves a

core i7 9700 K 16 gigs of memory we've

got our TX 2080

not too shabby I mean the thing is if

we're gonna be doing a test like this we

want to use something that's

representative of a high performance

gaming machine because if you use all

low power stuff and then you end up with

really great thermal results then all

you've managed to demonstrate is that

low powered hardware produces less heat

and doesn't run as hot as high

performance stuff so like what's the

point of that right zactly

which ones us the master case something

earlier yeah oh the maker 5t oh this is

an older one they did a bunch of

sponsored stuff with it oh no it's not

actually locked is it can we unlock it

from the inside and okay my left arm is

a little skinnier than my right for no

reason at all well problem solved

thermaltake wins by default power for

the motherboard there we go man if this

works I'm going to be just it really

shouldn't put them like you can't deny

the initial testing yeah you really

can't we weren't even gonna do this

video now people might be surprised how

many things we try and just never makes

it to video now normally these days we

use a triple 120 millimeter radiator but

again if Alex's calculations are correct

we should be able to get away with just

a double and get similar or even better

results so this is it for our build you

know it's actually got kind of like an

old-school charm to it I like it oh that

isn't there that is the heaviest bag of

coolant I have ever seen before

oh wow 34 kgs one part quikrete mortar

cement two and a quarter to three parts

masonry said yeah we're not a button

sand in there well yeah I'm obvious

reasons yeah that'd be stupid okay I'll

bring this guy oh I'll get a bucket of

water did you need my help I don't know

if for whatever reason I thought we need

to people want to like sort of hold it

and make sure but this is actually

working pretty well do we even need such

a big mixer we need like a liter of

concrete well um

have you ever made concrete before yes

actually

been a while though now that I think

about it okay I mean if we want to take

advantage of the cooling potential of it

then we have to make sure we actually

have enough concrete in there okay

that's starting to look kind of closer

look we're at a channel how the pros do

you want concrete tips you watch a

concrete Channel good look at this

yeah this will be great alright so yes

let's get a baseline reading with water

first oh great I was just gonna start

putting the concrete in no right yeah

good call good call

and that way we can make sure the system

actually even works - you know it's

funny you seem to be expressing a fair

bit of skepticism about this whole idea

but need I remind you that you were the

one who did the initial testing like

look at this hey it posted nice okay so

we've got working hardware now let's

just see if we can boot into Windows so

we're at about 35 to 40 degrees idle

let's go ahead and start our stress test

here okay pretty good about what I'd

expect so 55 to 60 degrees so everything

seems to be working normally so it seems

like it's basically leveled off like we

could run up for a while longer but

we're just at 62 degrees maximum yeah

this is exactly what we'd expect yeah

alright let's drain it we want to blow

it as much of the water as we can so

that we don't have I mean obviously the

concrete is just concrete and water so a

little bit of extra water isn't gonna

kill it but we don't want to get our

ratio off think you know I'm beginning

to have some second thoughts need to be

a bit water here hold on a second look

at this as it moves you can actually see

it turn more liquid that's what you were

saying was supposed to help us right see

like you can see it's really solid but

as it moves it actually turns to a

liquid so you can see the reservoir is

actually filling up a lot better than we

expected well than I expected anything I

don't know what your expectations were

so I am more than halfway done check

this out and what's crazy is you can

actually see that even though it's

clearly a liquid cuz it's flowing in

there it's kind of solid right now how's

that gonna affect things when you get

the pump okay uh we might need to power

cycle it a couple times but it also

might just work for those wondering this

is why we use half inch tubing because

you're gonna need a pretty thick with

two c's to in order to get concrete

through it so how do we do this without

making a mess all the tubes yeah oh

that's not a problem

spray it down with some water and then

just give it a wipe down with this I

mean it's not gonna be perfect but yeah

for sure oh this is exciting so we've

got two pieces of tubing filled so we

can go ahead and attach the pump so Alex

this is great I've got two of the tubes

on already mm-hmm and I can actually

attach the other one to the res right

now oh nice okay I guess this is the the

moment of truth so when we do get the

the heat and the pump going it should

like make it more liquidy and just kind

of get her on through but uh these are

like the heaviest tubes I think I've

ever felt and that that looks really

thick in there

oh that sound do you hear the palm wait

oh it's moving it

it sounds questionable but uh I think

you already don't know I've already

posted you have got to be kidding me

this shouldn't work okay so I want a

second I was pretty scared up to now but

why does this work can you are you

seeing this no though the tubes like are

you seeing this it is her idling it's

moving I don't think at 24 we really

4000 check this check the step 28

maximum no way art we jumped like rate

up to like 50 to 4 wait what do you mean

52 you mean on the other one yeah on the

last one we jumps like Oh even though

the coolant is moving like you can

clearly see there's flecks that aren't

it's almost like there's an inner

channel of movement but around the

outsides of the tubes it doesn't move at

all right you're not maximum 48 degrees

so like we can leave this for a bit the

thing about water cooling is that

normally you only get heat being

transferred at the block and at the rad

yeah because like the great thing about

waters that has such a high heat

capacity right yeah well that's exactly

why water is supposed to be the best

thing for liquid cooling well what the

thing is is that concrete is sort of

like a ceramic of sorts but a ceramic

that you can like have sort of flowing

around right so it not only is like

heating up there and there but it's also

like getting into the concrete that can

deposit the heat into the water all

along here and then like all along here

it will be just taking that heat away so

much sense that's why nobody likes

having like a concrete floor in their

bedroom like when you get out of bed and

you step onto a concrete floor

immediately it draws all the heat away

from your feet and like same thing with

like a basement then that's why your

basement never

gets hot in the summer so why has nobody

ever explored this before we are sitting

right now at anywhere from 49 to 50

degrees Celsius that is a significant

improvement and if you look at this the

CPU temp is actually at 28 degrees

that's a 10 degree Delta from just water

so this is incredible I mean it doesn't

look great I mean we could we can clean

it up a fair bit yeah everything but you

know it doesn't look amazing

but the results totally speak for

themselves I mean is it high-five time I

think so just my hands are kind of cold

for working which makes sense again

that's why your hands get cold when you

work with it like it's so obvious now

- you have to come see this what's up

just just come along it's a kind of bad

things oh no it's not the concrete PC is

it you know how we just kind of left it

last night yeah cause like you know my

god it's not running yeah I think we had

like a brownout or something last night

oh no yeah oh crap this like doesn't

Bend but like I don't know if you can

see in there but this is clearly

problematic yeah like we we could maybe

try turning it on seeing if it'll go but

oh I don't think that's a very good

shoot okay so we've definitely

identified the downside to concrete

cooling but that kind of comes with the

territory with any sort of enthusiast

grade solution and I don't think it's

unreasonable to expect people to have a

UPS so given that we got a 10 degree

improvement in our CPU temps I'm still

comfortable recommending it we have

certainly seen computer hardware

aficionados do more crazy things for

less benefit than that speaking of more
