1
00:00:00,080 --> 00:00:10,240
this coolant right here can drop your CPU and GPU temps by 7 degrees celsius

2
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

3
00:00:12,480 --> 00:00:17,119
have a graphy nanoparticle suspension

4
00:00:15,519 --> 00:00:20,960
that is 60 more thermally conductive than just

5
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

6
00:00:23,279 --> 00:00:29,119
segway to our sponsor thanks to our sponsor volta volta's new giga charger

7
00:00:27,119 --> 00:00:33,520
can charge four devices simultaneously offering either 130 watt or 200 watt

8
00:00:31,760 --> 00:00:38,280
fast charging depending on which model you get check it out today at the link

9
00:00:35,280 --> 00:00:38,280
below

10
00:00:45,040 --> 00:00:51,600
graphene was first discovered in 2004 and ever since then it's been theorized

11
00:00:48,800 --> 00:00:54,879
to be able to do basically everything well

12
00:00:52,399 --> 00:00:59,520
except leave the laboratory but for real though it's a fascinating material and

13
00:00:57,280 --> 00:01:02,640
it uh kind of smells like liquor and permanent

14
00:01:01,440 --> 00:01:07,760
markers graphene is basically just graphite but

15
00:01:05,360 --> 00:01:12,560
instead of having a 3d crystal structure it's two dimensional meaning it creates

16
00:01:10,080 --> 00:01:18,159
one atom thick sheets of carbon atoms in a hexagonal orientation these bonds are

17
00:01:15,200 --> 00:01:22,640
incredibly strong graphene is about 200 times stronger than steel but this

18
00:01:20,240 --> 00:01:27,200
arrangement also means atoms delocalize their electrons meaning they can move

19
00:01:24,640 --> 00:01:31,280
around more freely these loosey-goosey electrons is why graphene is such an

20
00:01:29,280 --> 00:01:35,360
incredible electrical and thermal conductor it's actually the most

21
00:01:33,600 --> 00:01:41,119
conductive material currently in existence so just how conductive well uh we have

22
00:01:39,439 --> 00:01:49,280
sheets of graphene right here and it has a thermal conductivity of

23
00:01:45,240 --> 00:01:52,079
1950 watts per meter kelvin that is 20

24
00:01:49,280 --> 00:01:56,240
times more than liquid metal so to show you just how thermally conductive these

25
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

26
00:01:58,399 --> 00:02:05,119
onto an ice cube i can slice into it like butter

27
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

28
00:02:07,360 --> 00:02:13,040
it's so weird can you see it on the thermal camera andy yeah it's

29
00:02:11,039 --> 00:02:18,720
it's so strange but these sheets have a problem because of

30
00:02:16,640 --> 00:02:22,800
the one atom thickness the thermal conductivity is just one

31
00:02:21,040 --> 00:02:26,879
directional so like this direction this direction really

32
00:02:25,040 --> 00:02:30,640
really good this way though

33
00:02:28,239 --> 00:02:35,760
through those different sheets super bad so why exactly

34
00:02:33,680 --> 00:02:41,360
should this stuff work for cooling your pc wouldn't having a bunch of graphite

35
00:02:39,040 --> 00:02:44,160
clogging up your microfins be a bit of a problem

36
00:02:42,319 --> 00:02:48,319
well maybe i guess we're going to find out if that is an issue

37
00:02:45,840 --> 00:02:54,080
but the basic principle is that you have a whole bunch of very very small

38
00:02:51,120 --> 00:02:58,720
very highly conductive bits suspended in the liquid and so it's kind of like the

39
00:02:56,400 --> 00:03:04,319
water goes over the hot bits and the graphene rapidly you know thermally

40
00:03:01,599 --> 00:03:08,480
conducts in which it then disperses back to the water as it's traveling between

41
00:03:06,000 --> 00:03:13,920
your hot bit and the radiator once you get to the radiator it very rapidly

42
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

43
00:03:16,319 --> 00:03:22,640
the CPU i guess it's about time that we just empty this out and

44
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

45
00:03:24,720 --> 00:03:32,080
cryofuel in it so that's essentially just water with additives to prevent

46
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

47
00:03:35,599 --> 00:03:41,840
oh that's heavy what do you think the chances are

48
00:03:39,280 --> 00:03:47,599
brandon of me leaving today with my clothing unstained by either graphite or

49
00:03:44,640 --> 00:03:50,480
red dye two out of ten two out of ten ooh

50
00:03:48,799 --> 00:03:55,440
yeah that's pretty accurate fortunately ek has an easy drain port so

51
00:03:52,959 --> 00:03:59,360
you know draining and filling the system should in theory be pretty simple oh

52
00:03:57,280 --> 00:04:02,879
geez that's not how that was supposed to go oh dear

53
00:04:01,439 --> 00:04:06,480
i kind of do need help

54
00:04:04,799 --> 00:04:11,200
nope we're fine we're fine we're doing fine brandon

55
00:04:08,480 --> 00:04:11,200
what have you done

56
00:04:13,680 --> 00:04:19,919
it does smell bad i just thought of a technology that we

57
00:04:17,440 --> 00:04:19,919
can use

58
00:04:22,560 --> 00:04:29,360
there we go it looks like below the drain port they have a little spot

59
00:04:27,360 --> 00:04:33,120
that allows the water to get into the chassis instead of out of the

60
00:04:31,040 --> 00:04:38,000
chassis i would say mostly that's my fault but

61
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

62
00:04:40,720 --> 00:04:48,160
port and a drain port this is going to be exceptionally

63
00:04:44,800 --> 00:04:48,160
easy to blow up

64
00:04:52,080 --> 00:04:58,720
maybe we just need several people to blow on it so keep on holding it there

65
00:04:55,680 --> 00:04:58,720
i'm going to blow okay

66
00:04:59,680 --> 00:05:04,720
is it working at all a little bit came out sure don't know

67
00:05:03,199 --> 00:05:09,039
how to make a muscle yeah

68
00:05:06,400 --> 00:05:13,360
it's a specialty of mine so in conclusion

69
00:05:10,720 --> 00:05:16,960
the ek fluid gaming which i said was very easy

70
00:05:14,720 --> 00:05:20,320
to drain in the ShortCircuit about it is not

71
00:05:18,000 --> 00:05:24,720
it's very difficult now our graphene coolant

72
00:05:22,800 --> 00:05:26,720
should be a lot more thermally conductive

73
00:05:26,000 --> 00:05:32,960
but graphene is also the most electrically conductive material in existence

74
00:05:31,440 --> 00:05:36,160
so that's not ideal for your computer i

75
00:05:35,199 --> 00:05:41,520
want to see what the resistance actually is so across

76
00:05:39,280 --> 00:05:46,800
this distance right here this is distilled water so it seems to be

77
00:05:44,320 --> 00:05:51,199
somewhere around i believe 10 mega ohms is what it's reading

78
00:05:48,479 --> 00:05:55,520
come over here to ek's cryofuel to three-ish something like that

79
00:05:54,720 --> 00:06:01,440
so ek's cryo-fuel is actually a lot more conductive than just distilled water

80
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

81
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

82
00:06:07,919 --> 00:06:15,039
so yeah this is exactly what it was doing before it started in the same spot

83
00:06:12,639 --> 00:06:18,960
yeah so while this is cryo fuel they probably are creating a coating

84
00:06:17,199 --> 00:06:23,199
creating a coating oh yeah that would make sense yes okay

85
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

86
00:06:25,919 --> 00:06:32,240
our distilled water we put the leads in and the resistance

87
00:06:30,160 --> 00:06:38,960
stays about the same whereas we put it in our cryo-fuel or graphene solution

88
00:06:35,759 --> 00:06:40,319
it starts going up pretty fast and we're

89
00:06:38,960 --> 00:06:45,600
guessing that's because of the corrosion inhibitors in here are slowly coating

90
00:06:43,199 --> 00:06:49,199
the leads and increasing the resistance between them so that's cool i just

91
00:06:47,840 --> 00:06:54,160
learned something now another thing that go chiller said

92
00:06:51,919 --> 00:06:58,160
is really great about their stuff is it's anti-foaming agents so

93
00:06:56,880 --> 00:07:02,639
foam is just terrible for your pc parts because

94
00:07:00,560 --> 00:07:07,680
little bubbles and stuff can form on the micro fins in your CPU or

95
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

96
00:07:09,840 --> 00:07:15,520
itself or it can be less intense but just like little bubbles appearing in

97
00:07:13,840 --> 00:07:21,360
your microfins and lowering the efficiency of your whole loop so i'm

98
00:07:18,000 --> 00:07:23,199
interested to check it out i have my

99
00:07:21,360 --> 00:07:28,080
highly technical you know little agitator here normally Linus is

100
00:07:25,360 --> 00:07:33,280
good but he's on vacation unfortunately now i tried paintbrushes no good don't

101
00:07:30,880 --> 00:07:36,160
agitate enough try this right here terrible result

102
00:07:34,880 --> 00:07:38,720
probably see the security footage of that right now

103
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

104
00:07:44,000 --> 00:07:48,639
now i'm not entirely sure

105
00:07:47,280 --> 00:07:52,319
that we can overcome that with the graphene solution but if we can't i'll

106
00:07:50,960 --> 00:07:58,240
be impressed oh now if i had to guess this will be

107
00:07:55,039 --> 00:07:59,039
pretty much the same as the water

108
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

109
00:08:03,280 --> 00:08:10,240
we're getting these bubbles that are forming which we weren't really getting with the

110
00:08:07,680 --> 00:08:13,520
distilled water so that sort of stuff happens in your

111
00:08:11,919 --> 00:08:18,400
loop and it's gonna be not a great time i'm curious to see if

112
00:08:16,160 --> 00:08:22,000
it'll behave any differently in our graphene solution it's gonna be a

113
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

114
00:08:26,639 --> 00:08:32,800
it almost seems like it's foaming a bit more um

115
00:08:30,639 --> 00:08:38,000
we're getting a lot of little bubbles kind of all over the place

116
00:08:35,039 --> 00:08:41,519
i would say that was worse so that's not a pass

117
00:08:40,320 --> 00:08:46,959
yeah it's like five minutes later and there still are a couple bubbles

118
00:08:44,959 --> 00:08:52,399
in this one nothing at all in the cryo fuel so i think they're uh

119
00:08:49,360 --> 00:08:53,600
their anti-foaming agent isn't too good

120
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

121
00:08:56,560 --> 00:09:02,800
sweet that's why i wanted to use this computer instead of another one like we

122
00:09:00,000 --> 00:09:06,560
could have just built a test bench oh geez have you watched full metal

123
00:09:04,959 --> 00:09:10,560
alchemist this reminds me of the thing that was

124
00:09:08,800 --> 00:09:14,480
bad i don't remember what it's called

125
00:09:12,320 --> 00:09:18,720
this is freaky and like the consistency just isn't

126
00:09:16,160 --> 00:09:23,120
quite right yeah oh

127
00:09:20,800 --> 00:09:23,120
oh

128
00:09:24,320 --> 00:09:30,000
yeah i've been marked i'm going to be graphing

129
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

130
00:09:31,760 --> 00:09:37,920
it's alive it's really odd it actually looks like

131
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

132
00:09:39,440 --> 00:09:46,279
this is going to be the strangest looking pump pull ever

133
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

134
00:10:05,200 --> 00:10:11,519
speed this seriously looks so freaking cool

135
00:10:08,560 --> 00:10:16,480
like i've seen black liquid in computers before but there's like somewhere

136
00:10:13,600 --> 00:10:20,959
between like a texture and just the void in this that is so sick

137
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

138
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

139
00:10:29,040 --> 00:10:35,600
for a computer so just need to record the temperature

140
00:10:33,519 --> 00:10:39,920
22.4 degrees that is slightly higher than it was before

141
00:10:37,600 --> 00:10:44,320
and then wait half an hour and find out how we did

142
00:10:41,519 --> 00:10:46,880
all right we're back half an hour later temperature's gone down in the room

143
00:10:45,519 --> 00:10:50,880
actually a little bit but the temperature has certainly gone up in the pc

144
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

145
00:10:53,200 --> 00:10:58,959
looks like it did nearly nothing frig

146
00:10:57,600 --> 00:11:05,440
it looks like in some spots it was maybe two degrees

147
00:11:02,079 --> 00:11:08,720
lower and the room was also a degree

148
00:11:05,440 --> 00:11:09,600
hotter when we ran this so maybe a max

149
00:11:08,720 --> 00:11:14,800
of three degrees difference but that's well

150
00:11:12,320 --> 00:11:19,839
within the margin of error well i wasn't happy with our test results we were

151
00:11:16,640 --> 00:11:22,640
within what like one two degrees and our

152
00:11:19,839 --> 00:11:25,200
test setup was not able to resolve that so

153
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

154
00:11:26,880 --> 00:11:33,440
the hvac we have a different motherboard that the vrms will not throttle on the

155
00:11:30,880 --> 00:11:39,040
CPU is pegged at five gigahertz all cores voltage is locked at 1.4 and this

156
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

157
00:11:41,040 --> 00:11:46,640
going to run this for half an hour come back chuck the graphene in there and

158
00:11:44,800 --> 00:11:49,760
with any luck it's cooler and we'll know for sure if it works

159
00:11:48,320 --> 00:11:53,839
i've run this twice now with the distilled water and we've gotten 76

160
00:11:52,079 --> 00:11:58,399
degrees max both times and the temperature in this room is quite

161
00:11:55,760 --> 00:12:01,440
consistent we're also seeing 200 watts sustained for the whole half an hour on

162
00:12:00,320 --> 00:12:06,880
the CPU so i'm pretty happy with this let's fill it up with crapping

163
00:12:05,680 --> 00:12:10,959
heck yeah oh it's so warm feels nice

164
00:12:09,279 --> 00:12:14,959
geez brandon why did we not do this in the first place

165
00:12:12,480 --> 00:12:14,959
i don't know

166
00:12:16,000 --> 00:12:22,279
all right you are no longer needed thank you thank you for your assistance

167
00:12:24,959 --> 00:12:30,560
yeah that was super easy oh we're seeing again like the distilled

168
00:12:29,120 --> 00:12:35,040
water wasn't doing anything weird but this is foaming at the top like their

169
00:12:32,639 --> 00:12:39,200
anti-foaming agent sucks all right this one's for all the marbles

170
00:12:36,880 --> 00:12:43,279
0.1 of a degree hotter than at the start of the last test

171
00:12:41,120 --> 00:12:48,320
very happy with that this test is actually good so no excuses this time

172
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

173
00:12:50,959 --> 00:12:56,959
on our CPU with this test setup problem

174
00:12:54,079 --> 00:12:59,440
is we're also one degree cooler in the room

175
00:12:58,000 --> 00:13:04,560
so yeah let's take a look at the logs but

176
00:13:01,680 --> 00:13:07,200
it's not looking great ah

177
00:13:05,360 --> 00:13:12,639
this might have actually done something it's only one or two degrees difference

178
00:13:09,440 --> 00:13:14,240
at first it was even more

179
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

180
00:13:16,720 --> 00:13:23,680
something brandon oh my gosh that's shocking honestly

181
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

182
00:13:26,480 --> 00:13:32,560
four same thing it is noticeably lower and

183
00:13:30,480 --> 00:13:38,000
let's change just for fun to our other water file since i ran that twice

184
00:13:35,440 --> 00:13:42,399
it's exactly the same it is lower well yeah i'm pretty glad that i redid our

185
00:13:40,000 --> 00:13:47,839
testing because this does show an improvement it's not massive but like

186
00:13:45,279 --> 00:13:52,639
three four degrees is measurable in our test setup that we have here so it does

187
00:13:50,079 --> 00:13:57,120
do something it's not complete snake oil and it looks really freaking cool like

188
00:13:55,360 --> 00:14:02,480
it's legitimately the coolest looking coolant i've ever seen

189
00:13:58,720 --> 00:14:04,160
so yeah i like it i want some more go

190
00:14:02,480 --> 00:14:08,079
chiller send us some mostly because it looks sick but it doesn't hurt your

191
00:14:06,399 --> 00:14:12,160
performance and maybe improves it so like awesome and you know what's also

192
00:14:10,000 --> 00:14:15,920
