a portion of this video was sponsored by constant contact watch till the end to

2
00:00:03,679 --> 00:00:10,880
learn more we've water cooled everything from phones and laptops to red 8k

3
00:00:08,240 --> 00:00:15,599
cameras but up until now our efforts have been entirely focused on cooling

4
00:00:13,040 --> 00:00:21,520
the devices we're using well what about us the users i mean i can't be the only

5
00:00:18,720 --> 00:00:26,240
one who gets like stress sweats when i'm the last one left on my team

6
00:00:23,840 --> 00:00:31,519
why aren't we water cooled yet what i want is a water cooled chair

7
00:00:29,439 --> 00:00:33,920
fortunately i know a guy

8
00:00:33,040 --> 00:00:39,040
meet the sweaty ass be gone 9000 patent

9
00:00:37,360 --> 00:00:44,719
definitely not pending and in the next 10 minutes or so we're going to show you

10
00:00:41,680 --> 00:00:47,840
how we did it and find out if it

11
00:00:44,719 --> 00:00:50,160
actually works because we haven't tried

12
00:00:47,840 --> 00:00:50,160
it yet

13
00:00:57,600 --> 00:01:04,799
i can't say this is the world's first water-cooled chair but what i can say is

14
00:01:03,039 --> 00:01:08,880
it's the best one probably i can also say that it's

15
00:01:07,040 --> 00:01:14,400
exactly the kind of overkill thing you'd expect to see on this channel

16
00:01:11,280 --> 00:01:16,960
this dominator ee black that maxnomic

17
00:01:14,400 --> 00:01:22,240
sent to our chop shop is now packing look at this

18
00:01:18,200 --> 00:01:25,200
700 watts of silverstone power and ek

19
00:01:22,240 --> 00:01:30,320
that's right full custom loop quality pump and reservoir combo unit and my

20
00:01:28,320 --> 00:01:35,119
favorite part is that we are not going to be circulating some lame room

21
00:01:32,880 --> 00:01:39,520
temperature water because a big chunk of that silverstone power supply is

22
00:01:37,119 --> 00:01:48,000
dedicated to this a 300 watt peltier chiller that's right

23
00:01:44,079 --> 00:01:49,920
we are going sub ambient baby why

24
00:01:48,000 --> 00:01:54,479
well here's the thing a water loop alone is great at moving

25
00:01:53,360 --> 00:02:00,079
heat around but if the ambient air is close to the

26
00:01:57,119 --> 00:02:05,759
user's skin temperature well think about it there would be zero gain and on a

27
00:02:03,360 --> 00:02:11,360
very hot day it could even have the opposite effect pushing heat into the

28
00:02:08,479 --> 00:02:16,160
chair warming the user's tush now we could have used the new and

29
00:02:13,840 --> 00:02:20,480
improved CPU chiller that alex and colin built but the idea was to create

30
00:02:18,480 --> 00:02:25,040
something here that could conceivably be daily driven and nobody wants to deal

31
00:02:22,959 --> 00:02:29,280
with that kind of hassle fortunately we had a couple of these

32
00:02:27,120 --> 00:02:32,560
aquarium water chillers lying around if you're a regular watcher of LTT which

33
00:02:31,200 --> 00:02:36,720
you should be by the way so hit that subscribe button you might remember this

34
00:02:34,400 --> 00:02:41,200
little guy from the first episode of bad cooling ideas with alex

35
00:02:38,959 --> 00:02:46,160
now they didn't work out for pc cooling because a modern CPU or graphics card

36
00:02:44,160 --> 00:02:51,840
will easily overwhelm the cooling capacity of one of these little guys but

37
00:02:49,440 --> 00:02:57,840
a resting human typically outputs anywhere between 100 to 120 watts

38
00:02:55,120 --> 00:03:02,640
well that should be easily manageable by our 300 watt peltier even accounting for

39
00:03:00,319 --> 00:03:06,080
some inefficiency now there were a few well

40
00:03:03,440 --> 00:03:11,200
extra steps to bring this to life our pump and res are mounted to a plate

41
00:03:08,640 --> 00:03:15,360
that we harvested from a seed quake kit with a nifty little 3d printed bracket

42
00:03:13,280 --> 00:03:17,519
courtesy of our prusa 3d printer farm we're going to drop that file in the

43
00:03:16,480 --> 00:03:24,319
video description if you want to replicate this for yourself then we needed to do some

44
00:03:21,760 --> 00:03:32,640
well let's call it fancy plumbing the pump outputs here to the peltier chiller

45
00:03:27,599 --> 00:03:36,000
which is okay so far so good but then

46
00:03:32,640 --> 00:03:38,480
whoa nelly it splits

47
00:03:36,000 --> 00:03:43,920
into dual five millimeter inputs into this manifold which further splits it

48
00:03:41,200 --> 00:03:50,000
into four loops that we can independently turn on and off at will

49
00:03:47,760 --> 00:03:54,000
we've got two bypass circuits you can see them here and here that we can open

50
00:03:52,480 --> 00:03:58,840
if we want to reduce restriction in our loop and then these two are for the

51
00:03:56,480 --> 00:04:03,680
backrest and the seat loops respectively the hardest part of this

52
00:04:01,120 --> 00:04:08,640
build honestly was figuring out how to integrate our tubing into the seat

53
00:04:05,599 --> 00:04:11,040
itself without making it noticeable we

54
00:04:08,640 --> 00:04:16,400
started by choosing a very soft silicone tubing to make it harder to feel any

55
00:04:14,000 --> 00:04:20,880
ridges through the chair's cover layer then after removing the covers from the

56
00:04:18,560 --> 00:04:26,240
polyurethane foam cushions collins sketched out their shapes and designed a

57
00:04:23,520 --> 00:04:32,639
flow track that was cut using his big format laser by defocusing the pinpoint

58
00:04:29,680 --> 00:04:37,919
laser beam on purpose colin was able to slowly etch down a roughly five

59
00:04:35,360 --> 00:04:43,040
millimeter wide by five millimeter deep groove running multiple passes so as not

60
00:04:40,320 --> 00:04:46,800
to scorch the urethane the silicone was then tucked into the channel and then

61
00:04:44,960 --> 00:04:50,560
tacked into place with foam safe super glue to keep it from wiggling its way

62
00:04:48,400 --> 00:04:55,199
loose which brings us to this moment all that's left

63
00:04:53,280 --> 00:04:59,840
is to tuck this foam into the chair

64
00:04:56,880 --> 00:05:03,199
bleed the air out of the system and uh well we're gonna find out if it works

65
00:05:01,520 --> 00:05:07,199
aren't we this is the kind of thing that is a hundred percent inspired by a real

66
00:05:05,280 --> 00:05:11,919
world personal need like i get freaking sweaty when i'm at

67
00:05:10,320 --> 00:05:16,960
my computer sometimes that was before you had ac that's that's true but like

68
00:05:14,880 --> 00:05:20,880
why pay for air conditioning an entire room if the only thing in it is

69
00:05:19,039 --> 00:05:25,360
your gaming self right this is more efficient this is eco-friendly jammer in

70
00:05:22,960 --> 00:05:28,400
there okay okay

71
00:05:26,800 --> 00:05:33,440
i got it lined up here there you go walk it in so we'll get that all up in there

72
00:05:30,479 --> 00:05:36,639
it's a water cooled chair and it's so much better than that other

73
00:05:35,280 --> 00:05:41,440
one yeah i mean no one's ever gonna see that part anyway now we install the back

74
00:05:39,520 --> 00:05:44,000
wow these manifolds are sick where'd we get these they're actually for an

75
00:05:42,800 --> 00:05:47,919
aquarium i love it they're air manifolds thank

76
00:05:46,400 --> 00:05:52,160
you fish nerds your next step while you're down there is we gotta drop the res out to fill it

77
00:05:51,360 --> 00:05:58,160
right right right right right oh careful 3d printed

78
00:05:56,000 --> 00:06:01,600
please unscrew it 3d printing great

79
00:06:00,000 --> 00:06:04,639
for most things great until you put a Linus in the

80
00:06:03,039 --> 00:06:08,560
equation all right moment of truth hey

81
00:06:09,680 --> 00:06:14,420
lttstore.com by the way cheers

82
00:06:13,680 --> 00:06:20,400
and wow really there's not a lot of water in

83
00:06:19,199 --> 00:06:26,080
there nope that's it eh something to note is that we do have a

84
00:06:23,520 --> 00:06:29,680
barbed fitting on here with no collar and no zip tie on it that would normally

85
00:06:28,080 --> 00:06:34,080
not be best practice if we were to deploy this in the long term but

86
00:06:31,600 --> 00:06:38,479
we're just you know trying it and actually we haven't shown you guys the

87
00:06:35,919 --> 00:06:43,919
switch yet so this switch controls the power supply which is jumpered so you

88
00:06:40,880 --> 00:06:46,400
just connect the green and any ground

89
00:06:43,919 --> 00:06:50,400
pin on the psu so what this does is it basically just allows us to power up the

90
00:06:47,840 --> 00:06:53,360
power supply without a computer no i don't know if you're going to feel

91
00:06:51,360 --> 00:06:56,880
anything right off the hop it's so hard to tell if it's a placebo effect it

92
00:06:55,039 --> 00:07:00,160
feels really chilly too though it's still got a little bit of warmth on it

93
00:06:58,400 --> 00:07:03,919
like i can see where your hands touch the back of the chair and i can see

94
00:07:01,919 --> 00:07:10,240
where my butt was on it before but i can also see it cooling down like

95
00:07:07,599 --> 00:07:14,240
hardcore right now compared to the one that does not have anything installed in

96
00:07:11,840 --> 00:07:18,160
it but initial impressions i can't feel the tubes like i can if i try really

97
00:07:16,319 --> 00:07:20,720
hard or if i feel with my fingers but with my back

98
00:07:19,599 --> 00:07:26,400
it's not the kind of thing i would notice one thing i can see though that

99
00:07:22,960 --> 00:07:28,560
we missed is that this area here

100
00:07:26,400 --> 00:07:32,400
should have absolutely been cooled you think i do think so because you can you

101
00:07:30,880 --> 00:07:36,160
can really see how much of the user's heat goes look

102
00:07:34,479 --> 00:07:41,680
how much heat is still in there thigh heat our control chair is sitting at

103
00:07:38,639 --> 00:07:43,440
about 25 degrees which is about room

104
00:07:41,680 --> 00:07:48,000
temperature right now our cooled chair is as high as 25

105
00:07:46,319 --> 00:07:53,680
degrees in the areas that we're not cooling which makes sense because

106
00:07:50,000 --> 00:07:56,160
foam is a good insulator

107
00:07:53,680 --> 00:08:01,280
in the areas that we are cooling it gets as low as

108
00:07:59,759 --> 00:08:06,800
23. oh it looks like there's actually some areas that are even lower so that might

109
00:08:04,639 --> 00:08:10,400
not sound like a big difference but a two degree difference

110
00:08:08,879 --> 00:08:15,520
is the difference between like the warm pool and the cold pool so

111
00:08:12,800 --> 00:08:15,520
see how it goes

112
00:08:16,720 --> 00:08:21,360
see this is where i get all hot and bothered

113
00:08:20,000 --> 00:08:25,919
unskipable crap i can definitely feel my back warming up

114
00:08:24,400 --> 00:08:28,879
yeah i can see the seat the seat has gained a little bit of heat even just

115
00:08:27,440 --> 00:08:35,839
from you like being around it comparatively all right you guys ready

116
00:08:33,200 --> 00:08:41,599
so here's the chair and here's my back so you're back is

117
00:08:37,919 --> 00:08:43,519
that 30.1 oh okay and the chair is at

118
00:08:41,599 --> 00:08:49,200
33 at your back and 31 and a half

119
00:08:47,120 --> 00:08:54,880
at your legs okay so we basically went up like a degree a

120
00:08:51,519 --> 00:08:56,560
minute on the chair if we look over to

121
00:08:54,880 --> 00:09:02,399
the cooled chair it is sitting at 23 degrees turbo node

122
00:09:00,399 --> 00:09:04,640
here we go oh oh

123
00:09:06,160 --> 00:09:13,360
that couple degree difference is

124
00:09:09,800 --> 00:09:15,920
huge especially after i've been sitting

125
00:09:13,360 --> 00:09:20,640
in a non-cooled chair like effectively with insulation all over my back i can

126
00:09:18,640 --> 00:09:24,240
feel it warming up but what i'll be interested to see is

127
00:09:22,080 --> 00:09:27,120
after the same amount of time if it's less warm and if i feel less warm

128
00:09:26,080 --> 00:09:31,920
remember now you're getting into this chair and you're hot too that's true two

129
00:09:30,000 --> 00:09:36,399
one okay what do we got all right are you guys ready

130
00:09:33,360 --> 00:09:38,800
this is it moment of truth okay okay

131
00:09:36,399 --> 00:09:43,200
minus is back how much how cool am i 30.5

132
00:09:40,560 --> 00:09:47,040
it's under your back the chair is 30

133
00:09:45,120 --> 00:09:51,600
right here right there 30.1

134
00:09:50,399 --> 00:09:56,640
but that's a lot colder 27.4

135
00:09:54,399 --> 00:10:01,200
i have more weight down here which is better for thermal transfer

136
00:09:59,200 --> 00:10:04,880
that makes sense because it's pushing it's compressing the foam and you're

137
00:10:02,480 --> 00:10:09,040
getting closer to the to the thing i like i don't remember what the initial

138
00:10:06,080 --> 00:10:13,839
numbers were but the way it feels guys like a degree or two here or there

139
00:10:11,760 --> 00:10:19,200
huge difference it is so much more comfortable you just wait lttstore.com

140
00:10:16,320 --> 00:10:23,120
nick yeah for real though we're we're not doing that water-cooled gamer chairs

141

if you guys enjoy this kind of hacky stuff go check out the area 51 water

157
00:11:28,640 --> 00:11:34,480
cooling video that we uploaded it's like a laptop it's water cooled it's crazy

158
00:11:32,399 --> 00:11:37,680
it's insane you haven't even tried it yet have you

159
00:11:36,000 --> 00:11:41,360
no it's noticeable right a little bit it's

160
00:11:40,320 --> 00:11:47,920
like you don't barely know i don't think it's enough i think we need to go more tubing

161
00:11:45,600 --> 00:11:50,640
no way okay you haven't sat in it for very long

162
00:11:49,040 --> 00:11:54,839
it's different it takes a minute but you get you do feel it

163
00:11:52,240 --> 00:11:58,640
that's weird awesome i'm glad this worked me too
