1
00:00:00,160 --> 00:00:06,960
now you guys might have seen the video we did recently where we disassembled an

2
00:00:04,080 --> 00:00:11,040
8k red camera with the intention of water cooling it and um

3
00:00:09,760 --> 00:00:16,640
well we do intend to do that eventually

4
00:00:13,920 --> 00:00:22,000
but uh you know baby steps right so the first step is making

5
00:00:19,279 --> 00:00:28,480
any water block and that is exactly what we have in store for you

6
00:00:24,400 --> 00:00:31,359
guys today the first ever Linus media

7
00:00:28,480 --> 00:00:35,040
group water block well except those ones they made in

8
00:00:32,399 --> 00:00:35,040
scrap air wars

9
00:00:42,879 --> 00:00:49,200
mack weldon wants you to be more comfortable so if you don't love your

10
00:00:46,879 --> 00:00:53,920
first pair of underwear you can keep it and get a full refund with their try on

11
00:00:51,120 --> 00:00:59,120
guarantee use code tech tips 20 to get 20 off at the link below so we have we

12
00:00:57,199 --> 00:01:03,760
have no we have no script and no structure for this whatsoever then is

13
00:01:01,120 --> 00:01:07,920
that do i understand this correctly yes okay

14
00:01:04,720 --> 00:01:10,240
so step one uh drawing inspiration you

15
00:01:07,920 --> 00:01:14,640
want to come over here david we actually did a video a little while ago where we

16
00:01:12,159 --> 00:01:18,560
bought a bunch of cheap water blocks off like aliexpress

17
00:01:16,320 --> 00:01:21,360
and um some of them actually were so simple that we looked at them

18
00:01:20,320 --> 00:01:24,479
went well we could do that with like

19
00:01:23,600 --> 00:01:29,840
you know half an hour in solidworks and then

20
00:01:27,040 --> 00:01:33,600
you know a couple hours of cnc time and that's exactly what we did pretty much

21
00:01:32,400 --> 00:01:37,840
yeah so this right here is even simpler than

22
00:01:35,520 --> 00:01:41,680
what we did it's kind of smart how they did it

23
00:01:39,119 --> 00:01:46,799
and like uh it's really smart how cheap it is to make this so if we look this is

24
00:01:44,400 --> 00:01:50,240
just acrylic and it would just be like six holes

25
00:01:48,960 --> 00:01:55,759
you're done so six holes and then you tap two

26
00:01:52,799 --> 00:01:59,680
g1 quarter threads and bippity boppity finished okay

27
00:01:57,520 --> 00:02:03,920
and then they don't even bother with doing anything besides holes in the

28
00:02:02,079 --> 00:02:07,040
copper because machining copper is a huge pain in the butt

29
00:02:05,680 --> 00:02:12,239
so they just have another piece of acrylic that's the right size for this o-ring and don't even bother with

30
00:02:10,000 --> 00:02:15,920
anything on the inside either wow

31
00:02:13,760 --> 00:02:20,160
this is like actually less than a dollar worth of

32
00:02:18,560 --> 00:02:25,920
materials pretty much yeah and so we kind of took some inspiration

33
00:02:23,440 --> 00:02:30,080
from that but it's it's too like easy even for us like

34
00:02:28,879 --> 00:02:33,360
because we're going to need to figure out how to properly machine copper to do

35
00:02:31,920 --> 00:02:39,360
some of the stuff we're doing later right so what have we done for okay so this is

36
00:02:37,680 --> 00:02:43,120
the other end of the spectrum yeah this is like

37
00:02:41,599 --> 00:02:47,440
pretty good where would you say that lands so by

38
00:02:45,040 --> 00:02:53,360
contrast this is a much more advanced design so starting with the base it

39
00:02:49,519 --> 00:02:54,640
requires machining on both the top and

40
00:02:53,360 --> 00:02:58,319
bottom so you can see they've countersunk the holes for these screws

41
00:02:56,959 --> 00:03:03,680
right here so that you're not going to even on a large died CPU you're not

42
00:03:01,120 --> 00:03:07,120
going to just have like screw raising the block away from it so it

43
00:03:05,200 --> 00:03:12,480
can't transfer heat and then it's actually got also much much finer work

44
00:03:10,560 --> 00:03:17,680
than we see on our very very basic just piece of copper

45
00:03:14,879 --> 00:03:21,440
here with these little fine fins that kind of guide the fluid as it goes

46
00:03:19,360 --> 00:03:24,800
across where the CPU die would be underneath and then away

47
00:03:23,680 --> 00:03:29,040
furthermore it's got a metal mid plate so this is to

48
00:03:27,120 --> 00:03:33,920
add rigidity and allow for mounting flexibility across various sockets and

49
00:03:31,360 --> 00:03:39,120
then it's got again double-sided machining work on the top here that not

50
00:03:36,799 --> 00:03:43,760
only just sort of allows it to be attached to the base but actually has

51
00:03:41,440 --> 00:03:47,680
guides for the fluid flow to help make it more efficient we're not really

52
00:03:45,360 --> 00:03:52,400
aspiring to this at this point are we no we're kind of getting half the way there

53
00:03:49,280 --> 00:03:53,599
so they do have the o-ring groove and

54
00:03:52,400 --> 00:03:58,840
those are actually really hard to machine because you need super high tolerances

55
00:03:56,799 --> 00:04:04,799
you mean in the groove low tolerances yes you need super low

56
00:04:01,920 --> 00:04:07,360
tolerances within this groove because otherwise i mean

57
00:04:06,560 --> 00:04:14,879
to put some perspective on how important that is if your o-ring doesn't fit

58
00:04:11,360 --> 00:04:17,759
correctly you leak water on your

59
00:04:14,879 --> 00:04:21,600
you know thousand dollar computer or thirty thousand dollar camera as it were

60
00:04:19,919 --> 00:04:26,320
we aren't going to be able to get these kind of fins unfortunately could we have

61
00:04:24,000 --> 00:04:31,919
done any kind of fins we could have potentially got like so the bit that we

62
00:04:29,120 --> 00:04:35,600
used this is our actual block here it was an eighth of an inch and that's

63
00:04:34,000 --> 00:04:39,520
getting it in like this groove right here is just a

64
00:04:37,199 --> 00:04:43,759
bit over an eighth of an inch got it so that's kind of like we could have like

65
00:04:40,960 --> 00:04:48,800
two fins we do have finer bits but running them in copper it isn't really

66
00:04:45,919 --> 00:04:52,240
working at the moment got it so i don't know i'm actually

67
00:04:50,479 --> 00:04:55,680
really stoked that we can just simply machine copper i wasn't expecting us to

68
00:04:54,320 --> 00:05:00,720
get this far i was thinking that we would start this

69
00:04:58,080 --> 00:05:04,880
and the bit would get like halfway in and then gum up and explode like we

70
00:05:03,199 --> 00:05:09,199
already have three more in the mail because i thought that we're just going to ruin a bunch so it might be

71
00:05:07,600 --> 00:05:14,479
surprising but this is a huge success for us okay

72
00:05:12,400 --> 00:05:19,759
a flat piece of copper with an o-ring in it

73
00:05:16,000 --> 00:05:21,039
do you want a metal like is it here

74
00:05:19,759 --> 00:05:26,080
thank you okay so have you tried this yet no

75
00:05:24,639 --> 00:05:29,360
so we have a couple more things that we need to do we need to tap the holes in

76
00:05:27,919 --> 00:05:34,160
here okay and in here so that the fittings go in

77
00:05:32,639 --> 00:05:38,320
and the bolt can go down and secure the

78
00:05:36,160 --> 00:05:43,600
whole thing together okay and then we're pretty much good to go okay so uh pitter

79
00:05:41,360 --> 00:05:47,840
patter let's get at her then yeah which one do you want to go at

80
00:05:45,759 --> 00:05:52,960
i want to do the plexi first because that seems a lot easier to replace if i

81
00:05:50,160 --> 00:05:57,280
bung it up this is really ugly acrylic that's just the machining marks there we

82
00:05:55,120 --> 00:06:00,000
could why did we machine the top of it to make sure that it's nice and flat

83
00:05:58,639 --> 00:06:05,199
when you get a piece of acrylic you don't necessarily know so we can get

84
00:06:02,400 --> 00:06:08,720
some sandpaper and make it a bit better okay but we aren't are we

85
00:06:07,440 --> 00:06:11,440
well we are a few leagues

86
00:06:11,440 --> 00:06:18,479
so here we go friends oh crap i'm not putting enough pressure it's kind of

87
00:06:15,759 --> 00:06:24,080
hard oh geez okay oh i am shredding this

88
00:06:21,520 --> 00:06:27,440
okay i need i just needed more pressure and the great news is that this is just

89
00:06:25,680 --> 00:06:31,039
the first one yeah oh we're getting pretty close yeah

90
00:06:29,520 --> 00:06:36,160
actually really close we were going to go into the table if we went another half turn how straight did we go

91
00:06:34,400 --> 00:06:38,960
actually not bad

92
00:06:39,360 --> 00:06:44,800
oh why are you doing that so

93
00:06:43,039 --> 00:06:49,759
again yeah number two tom petty was wrong

94
00:06:47,680 --> 00:06:52,160
the starting is the hardest part can i take this off yeah yeah take it

95
00:06:51,440 --> 00:06:56,720
off oh yeah see this side's much worse

96
00:06:54,560 --> 00:07:01,120
but we can probably work with that right yeah should be fine just flip it over

97
00:06:59,280 --> 00:07:03,840
um we need some fluid coming straight really

98
00:07:03,919 --> 00:07:09,599
definitely not trying to ow i just poked myself in the hand why don't you just

99
00:07:07,680 --> 00:07:13,680
ask for better tools instead of just making me use crappy ones

100
00:07:11,919 --> 00:07:17,919
i don't think you need that okay let's put it on the table all right okay like

101
00:07:15,440 --> 00:07:22,319
every every half turn or so you should go back and break the chip

102
00:07:19,599 --> 00:07:22,319
that's probably good

103
00:07:23,360 --> 00:07:29,360
all right times three more yep that was a good idea lubing it i

104
00:07:27,599 --> 00:07:32,240
take back what i said before look at that it's like a threaded hole

105
00:07:30,960 --> 00:07:35,919
and everything up in this biz like trying to make this

106
00:07:34,479 --> 00:07:39,199
with an angle grinder would have been a much more interesting video

107
00:07:39,520 --> 00:07:45,199
or the sawzall wasn't that like your entire like second

108
00:07:43,840 --> 00:07:50,080
day of work like through that heatsink everyone got so

109
00:07:47,919 --> 00:07:54,479
annoyed it was so loud right beside the editing right outside

110
00:07:52,240 --> 00:07:58,479
the editing deck so now we have to do what's

111
00:07:56,319 --> 00:08:01,840
kind of the make or break for this so we've got this o-ring here it's um

112
00:08:00,720 --> 00:08:07,680
eighth inch yep oh my god it's like not a continuous

113
00:08:04,960 --> 00:08:07,680
piece no

114
00:08:08,400 --> 00:08:12,960
in fact didn't Jake show both of us a site where you can just order any o-ring

115
00:08:11,599 --> 00:08:16,639
you want at any size you want why the hell did we do this

116
00:08:14,800 --> 00:08:19,840
because for a lot of the custom stuff that we're going to have to do later for

117
00:08:18,000 --> 00:08:24,240
like the reds and crab we're going to have to be able to make our own o-rings

118
00:08:22,000 --> 00:08:28,720
this is like way smaller than the groove that is not a tight fit oh it's it's not

119
00:08:26,800 --> 00:08:32,159
supposed to be a tight fit just let's just think about this one for a second

120
00:08:30,240 --> 00:08:36,000
yeah yeah you mush it down a bit but not that much

121
00:08:33,519 --> 00:08:40,000
oh this is the actual specification we have the parker o-ring handbook you go

122
00:08:37,839 --> 00:08:45,279
in there and you're like parker over yes it's like the bible for like

123
00:08:43,200 --> 00:08:48,480
engineers and stuff all right all right all right all right so what are we gonna

124
00:08:46,480 --> 00:08:51,920
do like like at the you know the fair where they take the special glue and

125
00:08:50,160 --> 00:08:55,680
they stick the two pieces of rope together in the water oh look one piece

126
00:08:53,600 --> 00:08:58,880
of rope it's cyanoacrylate it's amazing yep

127
00:08:56,800 --> 00:09:02,560
really yep i'm so unhappy right now

128
00:09:00,959 --> 00:09:08,000
that's really what we're using oh my god that's actually what we're doing yep

129
00:09:04,800 --> 00:09:09,600
what really it's cyanoacrylate

130
00:09:08,000 --> 00:09:13,600
i hate you all right here's your mark smart guy

131
00:09:11,839 --> 00:09:17,279
please don't slice my hand is this really a recommended way to do

132
00:09:15,440 --> 00:09:20,000
this you know what let's just see what happens

133
00:09:18,480 --> 00:09:24,000
okay you ever gotten the stuff on your hands before yes i have please don't

134
00:09:22,399 --> 00:09:27,600
yeah it's a really bad time yeah i know please don't yeah that's good that's

135
00:09:25,519 --> 00:09:31,120
good less is more well less is less but less is good

136
00:09:29,120 --> 00:09:35,040
is what i was trying to say oh wow it's not that close it's pretty bad well in

137
00:09:33,200 --> 00:09:38,480
fairness to me i think the whole thing's a little short anyway so we might as

138
00:09:36,800 --> 00:09:42,160
well just put it in there and see what happens oh

139
00:09:40,240 --> 00:09:46,959
actually no it's probably fine okay so i can just put it together now no no no no

140
00:09:44,640 --> 00:09:51,200
we need some petroleum just this this makes another appearance we need to get

141
00:09:48,880 --> 00:09:54,880
rid of this garbage this is the worst petroleum jelly i've ever encountered

142
00:09:52,959 --> 00:09:59,040
you're responsible for this oh we got to grease up our o-ring yeah okay it's

143
00:09:56,959 --> 00:10:02,839
disgusting it's like chunky i like my petroleum jelly like i like my

144
00:10:01,360 --> 00:10:07,040
peanut butter smooth okay

145
00:10:05,040 --> 00:10:10,480
so that's it um which uh which screws are we using

146
00:10:09,440 --> 00:10:16,160
those ones oh it's the wrong way oh it matters no no i know i did that on

147
00:10:14,399 --> 00:10:19,200
purpose but there's no way the o-rings for the fittings are to seal on the

148
00:10:17,519 --> 00:10:23,760
other side when i took those chunks oh yeah so we're just gambling here

149
00:10:21,760 --> 00:10:27,519
i mean theoretically there's nothing like really climactic what's happening

150
00:10:26,560 --> 00:10:32,399
right now please catch we're good okay hit me with another one

151
00:10:31,200 --> 00:10:37,279
two so that's it moment of truth

152
00:10:35,920 --> 00:10:41,040
yeah find out if it leaks

153
00:10:39,040 --> 00:10:44,560
um dot in the center and then little dots on either

154
00:10:42,720 --> 00:10:49,760
corner all right so yeah no why would we why would we drain the loop all we have to do we're going to open up a side here

155
00:10:48,160 --> 00:10:56,640
and we're above the water level in the reservoir so what should happen

156
00:10:53,760 --> 00:11:00,160
is we should start to draw in air is this open enough

157
00:10:58,240 --> 00:11:04,160
that's totally open so as long as we don't lift this up too high see how the

158
00:11:01,839 --> 00:11:08,240
water level rises there we go then we can have the tops of

159
00:11:06,399 --> 00:11:11,680
our tubes drained this is it moment of truth

160
00:11:12,320 --> 00:11:17,040
that's only a bit wait did we even thread this correctly well maybe we have

161
00:11:15,600 --> 00:11:20,160
to go from the other side we did tap it down from the other side

162
00:11:18,720 --> 00:11:23,839
oh that's gonna suck

163
00:11:22,399 --> 00:11:27,519
all right let's put it on the other way we'll do it the way you want this did

164
00:11:25,760 --> 00:11:31,360
actually come together pretty smoothly

165
00:11:29,200 --> 00:11:34,399
we're not done yet we can't be too happy at this moment

166
00:11:32,560 --> 00:11:39,600
oh this gives us a better look at the o-ring actually so you can see where we

167
00:11:37,040 --> 00:11:43,680
mushed it together there that might not leak so you were right the

168
00:11:42,320 --> 00:11:49,680
direction you thread it definitely matters either that or we didn't go through enough so that goes on there

169
00:11:47,839 --> 00:11:53,519
oh yeah that does that's not that's not before that yeah we could just zip tie

170
00:11:51,920 --> 00:11:57,279
it we could just not no no no no no this is a very well worn

171
00:11:55,920 --> 00:11:59,839
okay you know what yes we can just not just a sec

172
00:12:02,880 --> 00:12:08,880
no why would we why do we drain the loop okay this one goes on we can use this one

173
00:12:06,800 --> 00:12:12,240
well yeah that's also a good plan yeah that was the problem with these fittings

174
00:12:10,800 --> 00:12:17,279
so what's gonna happen now is i'm gonna move this down here

175
00:12:13,920 --> 00:12:19,360
and uh it's gonna fill with water

176
00:12:17,279 --> 00:12:23,279
you can actually see some water in it oh no it's completely full of water now

177
00:12:21,360 --> 00:12:27,360
okay and then we can seal up the top of our reservoir here where'd that fitting

178
00:12:25,040 --> 00:12:31,360
go i feel so bad for the people out there that like know what they're doing

179
00:12:28,959 --> 00:12:37,079
this must be like watching monkeys like just when i hit this button we're gonna

180
00:12:33,200 --> 00:12:37,079
find out if it leaks or not

181
00:12:38,639 --> 00:12:44,000
seems to be fine now it could take a while for us to find out if it's gonna

182
00:12:42,959 --> 00:12:48,800
leak but yes it actually

183
00:12:46,480 --> 00:12:51,760
does seem to be fine how about that

184
00:12:50,240 --> 00:12:55,279
just can't stop looking at it i'm just like so sure it's gonna leak why

185
00:12:54,320 --> 00:13:00,000
well you saw that o-ring yes

186
00:12:58,160 --> 00:13:03,680
look at it right now do you not trust parker i mean is this like is this like

187
00:13:02,000 --> 00:13:07,040
restaurants like working at a restaurant where as soon as you do that you'd never

188
00:13:05,120 --> 00:13:11,120
eat the food like as soon as you like make anything you just like never like

189
00:13:08,800 --> 00:13:15,120
you just never drive in a car again like knowing what the tolerances are like

190
00:13:13,200 --> 00:13:20,000
well cars are pretty good it's airplanes that really scare me their safety factor

191
00:13:17,760 --> 00:13:24,000
is like under 10 like normally on a car you do at least 50 and they're just like

192
00:13:21,519 --> 00:13:27,440
nope any extra weight is a bad thing so now what we just give her

193
00:13:25,600 --> 00:13:30,399
all right so well let's let's for say what we need to do yeah but it's gonna

194
00:13:28,639 --> 00:13:34,000
take a while before we're gonna know so we should probably give her

195
00:13:31,920 --> 00:13:39,519
okay sure all right we're giving her boom all right so here comes the heat

196
00:13:36,399 --> 00:13:41,920
max of 82 degrees to beat the aliexpress

197
00:13:39,519 --> 00:13:49,360
and that's this one that we i think is even more cheaply constructed

198
00:13:44,160 --> 00:13:51,440
than ours is that correct um ek is 64.

199
00:13:49,360 --> 00:13:54,959
so we're already up to 78. so

200
00:13:52,880 --> 00:13:57,839
oh wow really oh on the hottest corner on the hottest

201
00:13:56,399 --> 00:14:02,240
core yes oh also we never machined the bottom

202
00:13:59,839 --> 00:14:06,800
which they clearly did yeah have you seen what swift does with their skeeved

203
00:14:04,800 --> 00:14:11,519
thing where basically it like slices into the metal and then folds up a slice

204
00:14:10,399 --> 00:14:17,680
no it it's amazing can we get one of those

205
00:14:13,760 --> 00:14:21,680
machines nope no close all the tabs done

206
00:14:17,680 --> 00:14:21,680
and we're at 83 degrees damn it

207
00:14:22,720 --> 00:14:29,279
84. actually it settled back into 81. i wonder if that was just for me like like

208
00:14:27,120 --> 00:14:33,360
pushing on it i mean obviously you can't design a product to have the user just

209
00:14:31,120 --> 00:14:37,440
like hold it down well but we can just tighten these a bit more

210
00:14:34,880 --> 00:14:43,040
hey victory 80 degrees yay

211
00:14:39,360 --> 00:14:44,959
we beat aliexpress

212
00:14:43,040 --> 00:14:48,079
for a higher cost so there are some other factors to

213
00:14:46,399 --> 00:14:52,800
consider here too um like whether or not our base

214
00:14:50,959 --> 00:14:57,519
was made convex oops or concave by the uh mounting

215
00:14:55,760 --> 00:15:02,560
pressure of putting the top down on our o-ring that might be part of the reason

216
00:15:00,480 --> 00:15:06,079
why these guys went with this plastic plate like we

217
00:15:04,480 --> 00:15:10,240
actually don't know why they went with an acrylic plate oh wow they didn't even take the

218
00:15:09,199 --> 00:15:14,000
freaking who leaves like the paper on a

219
00:15:12,720 --> 00:15:18,880
finished good that they shipped to the customer so what was what was this one's result

220
00:15:17,120 --> 00:15:23,519
or did we not test that one we didn't test this one okay we just did the ek i

221
00:15:21,680 --> 00:15:28,720
mean it doesn't really matter we got our asses kicked by everything

222
00:15:25,279 --> 00:15:31,279
yeah but but

223
00:15:28,720 --> 00:15:35,279
the really positive takeaway here is that

224
00:15:32,480 --> 00:15:39,040
it really is not leaking so

225
00:15:36,240 --> 00:15:43,279
what that means for our future projects is that given that we're not going to be

226
00:15:40,880 --> 00:15:48,079
trying to cool a 7820x freaking 8-core CPU

227
00:15:46,320 --> 00:15:51,680
yeah we're going to be like we're in good shape yeah

228
00:15:49,839 --> 00:15:56,160
we can make water blocks to fit on anything now they won't be the best

229
00:15:53,440 --> 00:16:00,240
water blocks no they won't i really want to do the network switch yeah network

230
00:15:58,480 --> 00:16:04,079
network switch next and then

231
00:16:02,720 --> 00:16:08,399
a challenge yes like we only need to beat this

232
00:16:06,240 --> 00:16:11,920
that's going to be this sucks look at it it's terrible it's terrible

233
00:16:12,720 --> 00:16:16,880
okay i'm feeling good yeah

234
00:16:17,680 --> 00:16:23,120
