1
00:00:00,399 --> 00:00:08,719
now whether it's whiskey orangee juice or Mountain Dew I guarantee you if it's

2
00:00:05,359 --> 00:00:10,920
in fluid form somebody somewhere has

3
00:00:08,719 --> 00:00:16,279
filled up a loop with it cooled their computer and posted their results online

4
00:00:13,400 --> 00:00:22,080
so given how done to death this concept is I really never thought that we'd end

5
00:00:18,760 --> 00:00:26,320
up exploring the whole like weird or

6
00:00:22,080 --> 00:00:28,679
wacky exotic coolant concept that is

7
00:00:26,320 --> 00:00:37,360
until I read a comment from one of our viewers Jor leer St who suggested that

8
00:00:32,840 --> 00:00:40,320
we try using concrete now hold on I know

9
00:00:37,360 --> 00:00:47,199
what you guys are thinking but based on some of our preliminary testing I have

10
00:00:43,399 --> 00:00:50,360
reason to believe that this may actually

11
00:00:47,199 --> 00:00:52,600
work over the last couple of days Alex

12
00:00:50,360 --> 00:00:59,239
has put together all the materials that we're going to need to build what I

13
00:00:55,160 --> 00:01:02,550
believe is going to be the world's first

14
00:00:59,239 --> 00:01:05,650
concrete cooled gaming

15
00:01:09,840 --> 00:01:16,960
PC all right so the first thing we're going to need is some Hardware so we

16
00:01:14,320 --> 00:01:22,159
gathered up the parts for a pretty sweet modern gaming PC here we've got

17
00:01:18,880 --> 00:01:26,240
ourselves a uh cor i7

18
00:01:22,159 --> 00:01:30,200
9700k uh 16 gigs of memory we've got uh

19
00:01:26,240 --> 00:01:31,840
RTX uh 2080 not too shabby I mean the

20
00:01:30,200 --> 00:01:36,200
thing is if we're going to be doing a test like this we want to use something

21
00:01:34,079 --> 00:01:41,240
that's representative of a high performance gaming machine because if

22
00:01:38,399 --> 00:01:46,119
you use all low power stuff and then you end up with really great thermal results

23
00:01:44,159 --> 00:01:52,159
then all you've managed to demonstrate is that low powerered Hardware produces

24
00:01:49,280 --> 00:01:55,000
less heat and doesn't run as hot as high performance stuff so like what's the

25
00:01:53,880 --> 00:01:58,759
point of that right exactly which one is this the

26
00:01:57,479 --> 00:02:04,200
master case something or rather yeah oh the maker 5T oh this is an older one

27
00:02:00,920 --> 00:02:05,560
they did a bunch of um sponsored stuff

28
00:02:04,200 --> 00:02:12,319
with it oh no it's not actually locked is it

29
00:02:08,800 --> 00:02:14,319
um can we unlock it from the

30
00:02:12,319 --> 00:02:19,560
inside okay my left ARM is a little skinnier than my right for no reason at

31
00:02:16,720 --> 00:02:24,160
all well problem solved thermal take wins by

32
00:02:21,920 --> 00:02:30,519
default power for the motherboard there we go man if this

33
00:02:27,000 --> 00:02:34,519
works I'm going to be

34
00:02:30,519 --> 00:02:36,760
just it really shouldn't but then like

35
00:02:34,519 --> 00:02:41,040
you can't deny the initial testing yeah you really can't we weren't even going

36
00:02:38,920 --> 00:02:44,720
to do this video yeah people might be surprised how many things we try and

37
00:02:42,640 --> 00:02:51,000
just never makes it to video now normally these days we use a

38
00:02:47,360 --> 00:02:53,080
triple 120 mm radiator but again if

39
00:02:51,000 --> 00:02:56,879
Alex's calculations are correct we should be able to get away with just a

40
00:02:54,760 --> 00:03:02,080
double and get similar or even better results so this is it for our build you

41
00:02:59,480 --> 00:03:07,319
know it's actually got kind of like an old school charm to it I like

42
00:03:04,840 --> 00:03:14,760
it oh you doing there that is the heaviest bag of coolant I have ever seen

43
00:03:09,440 --> 00:03:17,200
before oh wow 34 kgs one part quick

44
00:03:14,760 --> 00:03:22,239
creep mortar cement two and A4 to three parts Masonry sand yeah we're we're not

45
00:03:20,159 --> 00:03:27,480
uh putting sand in there well yeah obviously obvious reasons yeah that'd be

46
00:03:24,720 --> 00:03:32,120
stupid okay I'll bring this guy I'll uh I'll get a bucket of water

47
00:03:30,720 --> 00:03:35,799
he what did you need my help for exactly I don't know for whatever reason I thought we'd need two people one to like

48
00:03:34,439 --> 00:03:42,120
sort of hold it and make sure but this is actually working pretty well do we even need such a big

49
00:03:38,720 --> 00:03:44,080
mixer we need like a liter of concrete

50
00:03:42,120 --> 00:03:49,720
well um have you ever made concrete before Yes actually it's been a while

51
00:03:46,840 --> 00:03:49,720
though now that I think about

52
00:03:50,439 --> 00:03:57,000
it yeah let's make sure we have enough

53
00:03:54,519 --> 00:04:00,599
yeah I think it needs more concrete okay I mean if we want to take advantage of

54
00:03:58,480 --> 00:04:04,319
the cooling potential of it then we have to make sure we actually have enough

55
00:04:02,159 --> 00:04:09,360
Concrete in there okay that's starting to look kind of closer look we're a tech

56
00:04:07,400 --> 00:04:13,680
Channel okay how the pros do it you want concrete tips you watch a concrete

57
00:04:11,000 --> 00:04:18,400
Channel just look at this yeah this will be great all right so I guess let's get

58
00:04:15,760 --> 00:04:23,400
a base line and reading with water first all right I was just going to start

59
00:04:20,400 --> 00:04:25,800
putting the concrete in no ah shoot

60
00:04:23,400 --> 00:04:29,440
right yeah good call good call and that way we can make sure the system actually

61
00:04:27,280 --> 00:04:32,880
even works too you know it's funny you see to be expressing a fair bit of

62
00:04:31,120 --> 00:04:37,199
skepticism about this whole idea but need I remind you that you were the one

63
00:04:34,960 --> 00:04:42,160
who did the initial testing like look at this hey it posted nice okay so we've

64
00:04:40,360 --> 00:04:46,639
got working Hardware now let's just see if we can boot into Windows so we're at

65
00:04:43,639 --> 00:04:49,280
about 35 to 40° idle let's go ahead and

66
00:04:46,639 --> 00:04:54,320
start our stress test here okay pretty good not bad it's like about what I'd

67
00:04:50,840 --> 00:04:56,400
expect so 55 to 60° so everything seems

68
00:04:54,320 --> 00:05:00,759
to be working normally so it seems like it's basically leveled off like we could

69
00:04:59,080 --> 00:05:08,520
run it for while longer but we're just at 62° maximum yeah this is exactly what

70
00:05:05,080 --> 00:05:09,960
we'd expect so all right let's drain it

71
00:05:08,520 --> 00:05:14,120
we want to blow out as much of the water as we can so that we don't have I mean

72
00:05:12,160 --> 00:05:16,639
obviously the concrete is just concrete and water so a little bit of extra water

73
00:05:15,600 --> 00:05:23,520
isn't going to kill it but we don't want to get our ratio off you know I'm beginning to have some

74
00:05:20,639 --> 00:05:29,720
second thoughts we might need to be a bit water here hold on a second look at

75
00:05:26,680 --> 00:05:31,520
this as it moves you can actually see it

76
00:05:29,720 --> 00:05:36,039
turn more liquid that's what you were saying was supposed to help us right see

77
00:05:33,639 --> 00:05:41,560
that like you can see it's really solid but as it moves it actually turns to a

78
00:05:39,240 --> 00:05:45,800
liquid so you can see the reservoir is actually filling up a lot better than we

79
00:05:43,520 --> 00:05:50,720
expected well than I expected anyway I don't know what your expectations were

80
00:05:47,800 --> 00:05:56,759
so I am more than halfway done check this out oh yeah not bad and what's

81
00:05:54,319 --> 00:06:00,199
crazy is you can actually see that even though it's clearly a liquid cuz it's

82
00:05:58,360 --> 00:06:04,319
flowing in there it's kind of solid right now how's that

83
00:06:03,039 --> 00:06:09,840
going to affect things when we get the pump hooked up uh we might need to power

84
00:06:08,319 --> 00:06:13,520
cycle it a couple times but it also might just work for those wondering this

85
00:06:11,479 --> 00:06:19,039
is why we used halfin tubing because you're going to need a pretty thick with

86
00:06:15,759 --> 00:06:21,960
two C's tube in order to get concrete

87
00:06:19,039 --> 00:06:26,680
through it so uh how how do I do this without making a mess oh the tubes yeah

88
00:06:24,919 --> 00:06:31,440
oh that's not a problem spray it down with some water and then just give it wipe down

89
00:06:30,000 --> 00:06:38,759
with this I mean it's not going to be perfect but yeah do yeah for sure um oh

90
00:06:35,520 --> 00:06:41,360
this is exciting so we've got two pieces

91
00:06:38,759 --> 00:06:46,639
of Tu being filled so we can go ahead and attach the

92
00:06:44,039 --> 00:06:51,039
pump so Alex this is great I've got two of the tubes on already

93
00:06:48,560 --> 00:06:58,160
mhm and I can actually attach the other one to the res right now oh nice so okay

94
00:06:54,560 --> 00:07:01,639
I guess this this the uh the moment of

95
00:06:58,160 --> 00:07:03,840
truth so we do get the uh the Heat and

96
00:07:01,639 --> 00:07:07,960
the pump going it should like make it more liquidy and just kind of get her on

97
00:07:06,520 --> 00:07:14,800
through but uh these are like the heaviest tubes I think I've ever felt

98
00:07:10,879 --> 00:07:14,800
and that that looks really thick in

99
00:07:20,759 --> 00:07:26,240
there oh that sound do you hear the pump

100
00:07:25,080 --> 00:07:31,759
yeah like wait oh uh it's moving dang

101
00:07:32,440 --> 00:07:38,400
it it sounds questionable but uh crap I

102
00:07:36,840 --> 00:07:41,560
think you were right is it going to boot though no I already

103
00:07:44,520 --> 00:07:49,039
posted you have got to be kidding me

104
00:07:47,720 --> 00:07:53,000
this shouldn't work okay so hold on a second I was

105
00:07:51,360 --> 00:07:58,840
pretty scared up to now but uh why does this work can you are you seeing this no

106
00:07:55,639 --> 00:08:01,120
no the tubes like are you seeing this

107
00:07:58,840 --> 00:08:09,520
okay we're idling it's moving idling at 24 we were doing 40 hold on check the

108
00:08:03,960 --> 00:08:13,440
check the step 28 maximum uh no way

109
00:08:09,520 --> 00:08:16,039
start we jumped like right up to like 52

110
00:08:13,440 --> 00:08:22,039
four wait what do you mean 52 you mean on the other one yeah on the last one we

111
00:08:17,800 --> 00:08:24,599
jumped like holy C crap even though the

112
00:08:22,039 --> 00:08:29,560
cool in is moving like you can clearly see there's Flex that aren't it's almost

113
00:08:27,759 --> 00:08:33,760
like there's an inner channel of movement but around the outsides of the

114
00:08:31,680 --> 00:08:38,680
tubes it doesn't move at all right and now maximum 48° so like we can leave

115
00:08:36,839 --> 00:08:44,159
this for a bit the thing about water cooling is that normally you only get

116
00:08:40,959 --> 00:08:46,600
heat being transferred at the Block and

117
00:08:44,159 --> 00:08:50,120
at the rad yeah because like the great thing about water is that has such a

118
00:08:48,000 --> 00:08:54,080
high heat capacity right yeah but that's exactly why water is supposed to be the

119
00:08:51,880 --> 00:08:59,240
best thing for liquid cooling well what the thing is is that concrete is sort of

120
00:08:57,279 --> 00:09:04,399
like a ceramic of sorts but a ceramic that you can like have sort of flowing

121
00:09:01,360 --> 00:09:06,360
around right so it not only is like

122
00:09:04,399 --> 00:09:12,680
heating up there and there but it's also like getting into the concrete that can

123
00:09:09,720 --> 00:09:18,440
deposit the heat into the water all along here and then like all along here

124
00:09:16,000 --> 00:09:22,640
it will be just taking that heat away as it after go that makes so much sense

125
00:09:20,480 --> 00:09:26,079
that's why nobody likes having like a concrete floor in their bedroom like

126
00:09:24,120 --> 00:09:30,880
when you get out of bed and you step onto a concrete floor immediately it

127
00:09:28,440 --> 00:09:34,959
draws all the Heat away from your feet and like same thing with like a basement

128
00:09:32,959 --> 00:09:39,600
then that's why your basement never gets hot in the summer so why has nobody ever

129
00:09:37,399 --> 00:09:46,519
explored this before we are sitting right now at anywhere from 49 to 50° C

130
00:09:44,720 --> 00:09:50,640
that is a significant Improvement and if you look at this the CPU temp is

131
00:09:49,120 --> 00:09:56,480
actually at 28° that's a 10° Delta from just water

132
00:09:54,399 --> 00:09:59,880
so this is incredible I mean it doesn't look great I mean we could we could

133
00:09:57,720 --> 00:10:05,320
clean it up a fair bit and everything you know it doesn't look amazing but the

134
00:10:03,480 --> 00:10:12,640
results totally speak for themselves I mean is it high five time I think so

135
00:10:08,959 --> 00:10:15,079
just ow my hands are kind of cold from

136
00:10:12,640 --> 00:10:19,360
working with the the concrete which makes sense again like that's why your

137
00:10:17,240 --> 00:10:25,839
hands get cold when you work with it like it's so obvious

138
00:10:23,120 --> 00:10:31,959
now Alex honest you have to come see this

139
00:10:29,040 --> 00:10:40,639
what's up what's up uh just just come along it's a okay sorry I'll be back

140
00:10:36,000 --> 00:10:43,800
kind of bad things hold on oh no it's

141
00:10:40,639 --> 00:10:46,240
not the concrete PC is it you know how

142
00:10:43,800 --> 00:10:49,320
we just kind of left it last night yeah cuz like you know we were here kind oh

143
00:10:47,760 --> 00:10:53,959
my God it's not running yeah I think we had like a brown

144
00:10:51,399 --> 00:11:01,240
out or something last night oh

145
00:10:57,279 --> 00:11:01,240
no the uh a

146
00:11:02,560 --> 00:11:11,399
uh oh crap this like doesn't

147
00:11:11,399 --> 00:11:18,079
Bend but like I don't know if you can see in there but this

148
00:11:15,440 --> 00:11:25,279
is clearly problematic yeah

149
00:11:20,760 --> 00:11:27,320
like hold on we we could maybe try uh

150
00:11:25,279 --> 00:11:30,639
turning it on and seeing if it'll go but I oh I don't think that's a very good

151
00:11:29,000 --> 00:11:35,839
idea no

152
00:11:32,440 --> 00:11:38,200
shoot Okay so we've definitely

153
00:11:35,839 --> 00:11:43,639
identified the downside to concrete cooling but that kind of comes with the

154
00:11:40,600 --> 00:11:45,440
territory with any sort of Enthusiast

155
00:11:43,639 --> 00:11:50,600
grade solution and I don't think it's unreasonable to expect people to have a

156
00:11:47,680 --> 00:11:55,079
UPS so given that we got a 10° improvement in our CPU temps I'm still

157
00:11:52,920 --> 00:12:00,680
comfortable recommending it we have certainly seen computer hardware

158
00:11:57,440 --> 00:12:03,120
