00:00:00.080 --> 00:00:10.240
this coolant right here can drop your CPU and GPU temps by 7 degrees celsius

00:00:07.759 --> 00:00:15.519
or it's a scam i actually don't know yet the people at go chiller claim that they

00:00:12.480 --> 00:00:17.119
have a graphy nanoparticle suspension

00:00:15.519 --> 00:00:20.960
that is 60 more thermally conductive than just

00:00:19.199 --> 00:00:25.039
normal everyday water so we're going to test it out just like i'm going to test out the

00:00:23.279 --> 00:00:29.119
segway to our sponsor thanks to our sponsor volta volta's new giga charger

00:00:27.119 --> 00:00:33.520
can charge four devices simultaneously offering either 130 watt or 200 watt

00:00:31.760 --> 00:00:38.280
fast charging depending on which model you get check it out today at the link

00:00:35.280 --> 00:00:38.280
below

00:00:45.040 --> 00:00:51.600
graphene was first discovered in 2004 and ever since then it's been theorized

00:00:48.800 --> 00:00:54.879
to be able to do basically everything well

00:00:52.399 --> 00:00:59.520
except leave the laboratory but for real though it's a fascinating material and

00:00:57.280 --> 00:01:02.640
it uh kind of smells like liquor and permanent

00:01:01.440 --> 00:01:07.760
markers graphene is basically just graphite but

00:01:05.360 --> 00:01:12.560
instead of having a 3d crystal structure it's two dimensional meaning it creates

00:01:10.080 --> 00:01:18.159
one atom thick sheets of carbon atoms in a hexagonal orientation these bonds are

00:01:15.200 --> 00:01:22.640
incredibly strong graphene is about 200 times stronger than steel but this

00:01:20.240 --> 00:01:27.200
arrangement also means atoms delocalize their electrons meaning they can move

00:01:24.640 --> 00:01:31.280
around more freely these loosey-goosey electrons is why graphene is such an

00:01:29.280 --> 00:01:35.360
incredible electrical and thermal conductor it's actually the most

00:01:33.600 --> 00:01:41.119
conductive material currently in existence so just how conductive well uh we have

00:01:39.439 --> 00:01:49.280
sheets of graphene right here and it has a thermal conductivity of

00:01:45.240 --> 00:01:52.079
1950 watts per meter kelvin that is 20

00:01:49.280 --> 00:01:56.240
times more than liquid metal so to show you just how thermally conductive these

00:01:54.240 --> 00:02:00.079
graphene sheets are i've got a little strip right here and if i put it down

00:01:58.399 --> 00:02:05.119
onto an ice cube i can slice into it like butter

00:02:03.200 --> 00:02:08.720
using the heat of my hands it feels like i'm touching an ice cube right now it's

00:02:07.360 --> 00:02:13.040
it's so weird can you see it on the thermal camera andy yeah it's

00:02:11.039 --> 00:02:18.720
it's so strange but these sheets have a problem because of

00:02:16.640 --> 00:02:22.800
the one atom thickness the thermal conductivity is just one

00:02:21.040 --> 00:02:26.879
directional so like this direction this direction really

00:02:25.040 --> 00:02:30.640
really good this way though

00:02:28.239 --> 00:02:35.760
through those different sheets super bad so why exactly

00:02:33.680 --> 00:02:41.360
should this stuff work for cooling your pc wouldn't having a bunch of graphite

00:02:39.040 --> 00:02:44.160
clogging up your microfins be a bit of a problem

00:02:42.319 --> 00:02:48.319
well maybe i guess we're going to find out if that is an issue

00:02:45.840 --> 00:02:54.080
but the basic principle is that you have a whole bunch of very very small

00:02:51.120 --> 00:02:58.720
very highly conductive bits suspended in the liquid and so it's kind of like the

00:02:56.400 --> 00:03:04.319
water goes over the hot bits and the graphene rapidly you know thermally

00:03:01.599 --> 00:03:08.480
conducts in which it then disperses back to the water as it's traveling between

00:03:06.000 --> 00:03:13.920
your hot bit and the radiator once you get to the radiator it very rapidly

00:03:11.200 --> 00:03:17.599
dumps all of its heat and cools down the water around it as it's going back to

00:03:16.319 --> 00:03:22.640
the CPU i guess it's about time that we just empty this out and

00:03:20.800 --> 00:03:27.360
see what actually works right yeah we're gonna empty this guy out it has ek's

00:03:24.720 --> 00:03:32.080
cryofuel in it so that's essentially just water with additives to prevent

00:03:29.360 --> 00:03:36.720
like moss growing inside of it and stuff so i think it's a pretty good comparison

00:03:35.599 --> 00:03:41.840
oh that's heavy what do you think the chances are

00:03:39.280 --> 00:03:47.599
brandon of me leaving today with my clothing unstained by either graphite or

00:03:44.640 --> 00:03:50.480
red dye two out of ten two out of ten ooh

00:03:48.799 --> 00:03:55.440
yeah that's pretty accurate fortunately ek has an easy drain port so

00:03:52.959 --> 00:03:59.360
you know draining and filling the system should in theory be pretty simple oh

00:03:57.280 --> 00:04:02.879
geez that's not how that was supposed to go oh dear

00:04:01.439 --> 00:04:06.480
i kind of do need help

00:04:04.799 --> 00:04:11.200
nope we're fine we're fine we're doing fine brandon

00:04:08.480 --> 00:04:11.200
what have you done

00:04:13.680 --> 00:04:19.919
it does smell bad i just thought of a technology that we

00:04:17.440 --> 00:04:19.919
can use

00:04:22.560 --> 00:04:29.360
there we go it looks like below the drain port they have a little spot

00:04:27.360 --> 00:04:33.120
that allows the water to get into the chassis instead of out of the

00:04:31.040 --> 00:04:38.000
chassis i would say mostly that's my fault but

00:04:35.520 --> 00:04:42.479
i thought it would work a bit better as i was saying because we have a fill

00:04:40.720 --> 00:04:48.160
port and a drain port this is going to be exceptionally

00:04:44.800 --> 00:04:48.160
easy to blow up

00:04:52.080 --> 00:04:58.720
maybe we just need several people to blow on it so keep on holding it there

00:04:55.680 --> 00:04:58.720
i'm going to blow okay

00:04:59.680 --> 00:05:04.720
is it working at all a little bit came out sure don't know

00:05:03.199 --> 00:05:09.039
how to make a muscle yeah

00:05:06.400 --> 00:05:13.360
it's a specialty of mine so in conclusion

00:05:10.720 --> 00:05:16.960
the ek fluid gaming which i said was very easy

00:05:14.720 --> 00:05:20.320
to drain in the ShortCircuit about it is not

00:05:18.000 --> 00:05:24.720
it's very difficult now our graphene coolant

00:05:22.800 --> 00:05:26.720
should be a lot more thermally conductive

00:05:26.000 --> 00:05:32.960
but graphene is also the most electrically conductive material in existence

00:05:31.440 --> 00:05:36.160
so that's not ideal for your computer i

00:05:35.199 --> 00:05:41.520
want to see what the resistance actually is so across

00:05:39.280 --> 00:05:46.800
this distance right here this is distilled water so it seems to be

00:05:44.320 --> 00:05:51.199
somewhere around i believe 10 mega ohms is what it's reading

00:05:48.479 --> 00:05:55.520
come over here to ek's cryofuel to three-ish something like that

00:05:54.720 --> 00:06:01.440
so ek's cryo-fuel is actually a lot more conductive than just distilled water

00:05:59.680 --> 00:06:05.759
and we come over to our graphene solution it's about the same as ek's cryo-fuel i

00:06:04.720 --> 00:06:09.199
don't know how much i trust these numbers i'm going to call on the engineers

00:06:07.919 --> 00:06:15.039
so yeah this is exactly what it was doing before it started in the same spot

00:06:12.639 --> 00:06:18.960
yeah so while this is cryo fuel they probably are creating a coating

00:06:17.199 --> 00:06:23.199
creating a coating oh yeah that would make sense yes okay

00:06:21.440 --> 00:06:27.600
so as it naturally sits for longer it'll build up a coating so it seems like in

00:06:25.919 --> 00:06:32.240
our distilled water we put the leads in and the resistance

00:06:30.160 --> 00:06:38.960
stays about the same whereas we put it in our cryo-fuel or graphene solution

00:06:35.759 --> 00:06:40.319
it starts going up pretty fast and we're

00:06:38.960 --> 00:06:45.600
guessing that's because of the corrosion inhibitors in here are slowly coating

00:06:43.199 --> 00:06:49.199
the leads and increasing the resistance between them so that's cool i just

00:06:47.840 --> 00:06:54.160
learned something now another thing that go chiller said

00:06:51.919 --> 00:06:58.160
is really great about their stuff is it's anti-foaming agents so

00:06:56.880 --> 00:07:02.639
foam is just terrible for your pc parts because

00:07:00.560 --> 00:07:07.680
little bubbles and stuff can form on the micro fins in your CPU or

00:07:05.280 --> 00:07:11.840
in your pump and like if it gets out of hand in the pump it can run dry and kill

00:07:09.840 --> 00:07:15.520
itself or it can be less intense but just like little bubbles appearing in

00:07:13.840 --> 00:07:21.360
your microfins and lowering the efficiency of your whole loop so i'm

00:07:18.000 --> 00:07:23.199
interested to check it out i have my

00:07:21.360 --> 00:07:28.080
highly technical you know little agitator here normally Linus is

00:07:25.360 --> 00:07:33.280
good but he's on vacation unfortunately now i tried paintbrushes no good don't

00:07:30.880 --> 00:07:36.160
agitate enough try this right here terrible result

00:07:34.880 --> 00:07:38.720
probably see the security footage of that right now

00:07:39.680 --> 00:07:47.280
ah this carry here is pretty good so if we take a look there's a lot of bubbles forming right

00:07:44.000 --> 00:07:48.639
now i'm not entirely sure

00:07:47.280 --> 00:07:52.319
that we can overcome that with the graphene solution but if we can't i'll

00:07:50.960 --> 00:07:58.240
be impressed oh now if i had to guess this will be

00:07:55.039 --> 00:07:59.039
pretty much the same as the water

00:07:58.240 --> 00:08:04.560
oh actually it's foaming a little bit you can kind of see on the top there

00:08:03.280 --> 00:08:10.240
we're getting these bubbles that are forming which we weren't really getting with the

00:08:07.680 --> 00:08:13.520
distilled water so that sort of stuff happens in your

00:08:11.919 --> 00:08:18.400
loop and it's gonna be not a great time i'm curious to see if

00:08:16.160 --> 00:08:22.000
it'll behave any differently in our graphene solution it's gonna be a

00:08:20.400 --> 00:08:27.360
bit hard to tell exactly what's going on given it's black but let's give it a go

00:08:26.639 --> 00:08:32.800
it almost seems like it's foaming a bit more um

00:08:30.639 --> 00:08:38.000
we're getting a lot of little bubbles kind of all over the place

00:08:35.039 --> 00:08:41.519
i would say that was worse so that's not a pass

00:08:40.320 --> 00:08:46.959
yeah it's like five minutes later and there still are a couple bubbles

00:08:44.959 --> 00:08:52.399
in this one nothing at all in the cryo fuel so i think they're uh

00:08:49.360 --> 00:08:53.600
their anti-foaming agent isn't too good

00:08:52.399 --> 00:08:57.920
but let's chuck her in i'm actually excited i think this is going to look friggin

00:08:56.560 --> 00:09:02.800
sweet that's why i wanted to use this computer instead of another one like we

00:09:00.000 --> 00:09:06.560
could have just built a test bench oh geez have you watched full metal

00:09:04.959 --> 00:09:10.560
alchemist this reminds me of the thing that was

00:09:08.800 --> 00:09:14.480
bad i don't remember what it's called

00:09:12.320 --> 00:09:18.720
this is freaky and like the consistency just isn't

00:09:16.160 --> 00:09:23.120
quite right yeah oh

00:09:20.800 --> 00:09:23.120
oh

00:09:24.320 --> 00:09:30.000
yeah i've been marked i'm going to be graphing

00:09:27.519 --> 00:09:33.120
possessed i don't know i don't even know it like it's shimmering it looks like

00:09:31.760 --> 00:09:37.920
it's alive it's really odd it actually looks like

00:09:35.519 --> 00:09:41.200
it's infecting the computer okay brandon can you give us some slow-mo i feel like

00:09:39.440 --> 00:09:46.279
this is going to be the strangest looking pump pull ever

00:10:01.760 --> 00:10:06.320
we're just here in the BIOS i need to change all the fans back to be full

00:10:05.200 --> 00:10:11.519
speed this seriously looks so freaking cool

00:10:08.560 --> 00:10:16.480
like i've seen black liquid in computers before but there's like somewhere

00:10:13.600 --> 00:10:20.959
between like a texture and just the void in this that is so sick

00:10:18.640 --> 00:10:26.480
i can't get over it so to test this out we're just doing the two big dirties so

00:10:23.680 --> 00:10:30.800
fermark and prime95 run them both at the same time about as brutal as you can be

00:10:29.040 --> 00:10:35.600
for a computer so just need to record the temperature

00:10:33.519 --> 00:10:39.920
22.4 degrees that is slightly higher than it was before

00:10:37.600 --> 00:10:44.320
and then wait half an hour and find out how we did

00:10:41.519 --> 00:10:46.880
all right we're back half an hour later temperature's gone down in the room

00:10:45.519 --> 00:10:50.880
actually a little bit but the temperature has certainly gone up in the pc

00:10:49.600 --> 00:10:56.079
it looks like we're gonna have to refer to the graphs here yeah sorry uh it

00:10:53.200 --> 00:10:58.959
looks like it did nearly nothing frig

00:10:57.600 --> 00:11:05.440
it looks like in some spots it was maybe two degrees

00:11:02.079 --> 00:11:08.720
lower and the room was also a degree

00:11:05.440 --> 00:11:09.600
hotter when we ran this so maybe a max

00:11:08.720 --> 00:11:14.800
of three degrees difference but that's well

00:11:12.320 --> 00:11:19.839
within the margin of error well i wasn't happy with our test results we were

00:11:16.640 --> 00:11:22.640
within what like one two degrees and our

00:11:19.839 --> 00:11:25.200
test setup was not able to resolve that so

00:11:23.440 --> 00:11:29.200
here we go different test setup we're in Linus's office where we have control of

00:11:26.880 --> 00:11:33.440
the hvac we have a different motherboard that the vrms will not throttle on the

00:11:30.880 --> 00:11:39.040
CPU is pegged at five gigahertz all cores voltage is locked at 1.4 and this

00:11:36.800 --> 00:11:42.560
is gonna be an actually good test so we've got distilled water in here we're

00:11:41.040 --> 00:11:46.640
going to run this for half an hour come back chuck the graphene in there and

00:11:44.800 --> 00:11:49.760
with any luck it's cooler and we'll know for sure if it works

00:11:48.320 --> 00:11:53.839
i've run this twice now with the distilled water and we've gotten 76

00:11:52.079 --> 00:11:58.399
degrees max both times and the temperature in this room is quite

00:11:55.760 --> 00:12:01.440
consistent we're also seeing 200 watts sustained for the whole half an hour on

00:12:00.320 --> 00:12:06.880
the CPU so i'm pretty happy with this let's fill it up with crapping

00:12:05.680 --> 00:12:10.959
heck yeah oh it's so warm feels nice

00:12:09.279 --> 00:12:14.959
geez brandon why did we not do this in the first place

00:12:12.480 --> 00:12:14.959
i don't know

00:12:16.000 --> 00:12:22.279
all right you are no longer needed thank you thank you for your assistance

00:12:24.959 --> 00:12:30.560
yeah that was super easy oh we're seeing again like the distilled

00:12:29.120 --> 00:12:35.040
water wasn't doing anything weird but this is foaming at the top like their

00:12:32.639 --> 00:12:39.200
anti-foaming agent sucks all right this one's for all the marbles

00:12:36.880 --> 00:12:43.279
0.1 of a degree hotter than at the start of the last test

00:12:41.120 --> 00:12:48.320
very happy with that this test is actually good so no excuses this time

00:12:46.160 --> 00:12:54.079
so it's been half an hour and it does look like that we are one degree cooler

00:12:50.959 --> 00:12:56.959
on our CPU with this test setup problem

00:12:54.079 --> 00:12:59.440
is we're also one degree cooler in the room

00:12:58.000 --> 00:13:04.560
so yeah let's take a look at the logs but

00:13:01.680 --> 00:13:07.200
it's not looking great ah

00:13:05.360 --> 00:13:12.639
this might have actually done something it's only one or two degrees difference

00:13:09.440 --> 00:13:14.240
at first it was even more

00:13:12.639 --> 00:13:18.000
but it is enough like if you look at this graph like just i think it might have actually done

00:13:16.720 --> 00:13:23.680
something brandon oh my gosh that's shocking honestly

00:13:21.279 --> 00:13:27.519
let's see here let's go like individual core and see what they'd here's core

00:13:26.480 --> 00:13:32.560
four same thing it is noticeably lower and

00:13:30.480 --> 00:13:38.000
