1
00:00:00,080 --> 00:00:08,559
for our last sleeper gaming pc the goal was to build the most powerful compact

2
00:00:05,680 --> 00:00:13,040
desktop rig that we could but this time our objective is a little different this

3
00:00:10,800 --> 00:00:17,520
video is brought to you by sea sonic and the rig's going to be powered by their

4
00:00:14,559 --> 00:00:23,439
prime platinum 1300 watt and it is gonna have everything you see here

5
00:00:20,640 --> 00:00:27,840
everything you see here and

6
00:00:24,400 --> 00:00:29,279
everything you see back there

7
00:00:27,840 --> 00:00:36,079
yeah most of that really didn't work out but

8
00:00:33,200 --> 00:00:41,280
sleeper number three margaret well she's a taskmaster

9
00:00:38,239 --> 00:00:45,840
she's the biggest baddest hardest

10
00:00:41,280 --> 00:00:45,840
sleeper pc that we've ever built and

11
00:00:46,320 --> 00:00:53,919
did i mention that she's beautiful

12
00:00:57,360 --> 00:01:03,760
floppy bigger floppy jazz floppy dvd

13
00:01:00,879 --> 00:01:07,840
rewriter dvd rom what like what is this is this a zip zip disc or is it just a

14
00:01:06,000 --> 00:01:14,320
cooling fan like what the hell is this um hard drive hot swappable card reader

15
00:01:11,520 --> 00:01:18,240
Windows 2000 professional one to two CPU this is going to be a lot of work

16
00:01:16,960 --> 00:01:21,439
yeah you know what makes it a lot harder

17
00:01:20,159 --> 00:01:26,640
the chiller the chiller

18
00:01:24,000 --> 00:01:30,720
and the carbon fiber tubing what why are we doing carbon fiber tubing are you

19
00:01:28,159 --> 00:01:35,520
nuts the first thing we needed to do was figure out if our water chiller would

20
00:01:33,439 --> 00:01:40,799
even fit inside the case we salvaged from our friends at free geek vancouver

21
00:01:38,079 --> 00:01:44,880
like sure the case is massive but there's still plenty of room for error

22
00:01:43,119 --> 00:01:49,520
in something like this we disassembled the chiller to find out

23
00:01:46,880 --> 00:01:55,680
what was inside and then removed all the pc components in our case to make space

24
00:01:53,200 --> 00:02:00,640
this is a situation yes it turns out that eyeballing things

25
00:01:58,320 --> 00:02:04,719
is not quite a substitute for measuring them

26
00:02:01,360 --> 00:02:04,719
well it can all fit

27
00:02:05,439 --> 00:02:10,640
we can get it in but we might ruin the condenser because we have to bend these

28
00:02:09,119 --> 00:02:13,780
copper tubes oh yeah that's going to be a super bad time

29
00:02:12,879 --> 00:02:19,120
or we could just be like

30
00:02:17,360 --> 00:02:23,200
hey kapow i'm sorry this project won't be as

31
00:02:20,879 --> 00:02:27,440
advertised i think that is exactly what we're gonna do we're gonna go

32
00:02:24,959 --> 00:02:32,560
overkill water cooling with the carbon fiber tubing is that not cool enough

33
00:02:30,080 --> 00:02:36,800
yeah are you not entertained and then we're gonna have to i mean i

34
00:02:34,560 --> 00:02:39,840
still want to revisit this yeah i think it's just a matter of finding the right

35
00:02:38,080 --> 00:02:45,040
chassis like if we find an old server chassis or something

36
00:02:41,280 --> 00:02:47,120
there is no reason we couldn't do that

37
00:02:45,040 --> 00:02:50,400
i think the best way is to just start by building a computer in here that's air

38
00:02:48,720 --> 00:02:55,440
cooled and then locating everything where we think it'll work

39
00:02:51,920 --> 00:02:55,440
are you pumped oh yeah

40
00:02:56,720 --> 00:03:00,800
oh those good sponsor dollars

41
00:03:01,120 --> 00:03:09,440
for this build we're looking to have not just insane gaming power but also crazy

42
00:03:07,760 --> 00:03:17,360
workstation power with that in mind our CPU selection was

43
00:03:12,239 --> 00:03:19,920
easy the threadripper 2990x is a 32 core

44
00:03:17,360 --> 00:03:26,000
64 thread beast and it gives up some gaming performance

45
00:03:22,400 --> 00:03:28,959
but it utterly embarrasses even Intel's

46
00:03:26,000 --> 00:03:33,760
top-end hddt chip in multi-threaded workloads

47
00:03:30,560 --> 00:03:37,599
for the GPU we're going with NVIDIA's

48
00:03:33,760 --> 00:03:38,720
GeForce rtx 2080 ti

49
00:03:37,599 --> 00:03:43,840
i'd like to say that there's a good reason for it but it's just the best GPU

50
00:03:40,959 --> 00:03:49,280
for gaming will it be enough i i think so i guess

51
00:03:47,040 --> 00:03:53,519
that we could have gone for two but i don't know i wasn't really in the mood

52
00:03:51,920 --> 00:03:57,920
given what we've been hearing about these it's extra important that we make

53
00:03:55,280 --> 00:04:02,159
sure that everything's working before we bother water cooling it power is being

54
00:04:00,239 --> 00:04:08,239
taken care of by a sea sonic prime platinum 1300 watt which admittedly is a

55
00:04:05,519 --> 00:04:13,280
bit overkill for this system but on the plus side it's going to operate

56
00:04:10,319 --> 00:04:18,639
in silent mode basically the entire time and like come on if seasonic offers you

57
00:04:16,239 --> 00:04:22,000
a 1300 watt power supply for the project they're sponsoring

58
00:04:20,079 --> 00:04:27,440
you take it so for this build i'm going to be using a dim.2

59
00:04:25,040 --> 00:04:31,040
it's no real reason to use it besides just

60
00:04:28,720 --> 00:04:34,639
i've had drives fail when they're down below there before and water cooling

61
00:04:32,639 --> 00:04:38,400
builds and man that's a horrible time with everything installed it was time to

62
00:04:36,560 --> 00:04:40,880
make sure that all our components were in working

63
00:04:41,680 --> 00:04:49,800
it order pretty easy that wasn't too bad yeah i know a0

64
00:04:46,880 --> 00:04:55,520
detect memory oh damn it

65
00:04:55,520 --> 00:05:00,960
just a tiny bit of thermal paste i wonder if that's what was causing our

66
00:04:58,639 --> 00:05:00,960
issues

67
00:05:01,919 --> 00:05:07,919
okay so the the motherboard that we had before it's

68
00:05:05,600 --> 00:05:11,280
just dead um so that's why we're having so many issues

69
00:05:09,680 --> 00:05:15,440
and it's like it's like a week and a half since i've

70
00:05:13,199 --> 00:05:18,960
been working on this because it's

71
00:05:16,720 --> 00:05:22,720
bad things were happening but hopefully we're gonna

72
00:05:20,720 --> 00:05:28,320
get back here and in the next day or so this will be a fully functioning pc but

73
00:05:25,199 --> 00:05:30,800
i guess we'll find out in the future

74
00:05:28,320 --> 00:05:33,680
all right goodbye

75
00:05:34,080 --> 00:05:40,320
all right new zenith extreme

76
00:05:37,759 --> 00:05:42,560
this one does not have any bent pins so

77
00:05:42,639 --> 00:05:47,520
with any luck it will work just fine

78
00:05:51,039 --> 00:05:58,800
code ad detect memory this is very bad dennis

79
00:05:56,320 --> 00:06:02,639
our CPU might be dead we're we're gonna have to go with

80
00:06:00,000 --> 00:06:07,120
something else here all right so she's working now um i

81
00:06:05,680 --> 00:06:12,240
talked to it nicely like i haven't recommended and you just call it an edge

82
00:06:09,680 --> 00:06:16,240
okay it's not an it's a she thank you margaret okay

83
00:06:14,080 --> 00:06:21,520
i'm i'm sorry baby okay we need to put a water cooling loop in here

84
00:06:18,800 --> 00:06:25,600
here's what i think why don't you use a vertical adapter bracket for the card

85
00:06:23,759 --> 00:06:29,759
and have the card vertical that will give you space in behind

86
00:06:27,520 --> 00:06:33,120
here to put the pump and the tubing to go up

87
00:06:30,960 --> 00:06:36,960
with the loop planned out the components were removed and it was time to drill

88
00:06:35,360 --> 00:06:40,280
out the rivets to make space for our water cooling

89
00:06:51,120 --> 00:06:57,280
and the idea is that this right here will be the new the new power supply

90
00:06:55,199 --> 00:07:01,840
holder and also will allow for us to have cable management in the back this

91
00:07:00,160 --> 00:07:06,720
if it works we'll be made out of aluminum on the cnc router but

92
00:07:04,639 --> 00:07:10,240
we will see in a couple seconds that it's gonna be a good time

93
00:07:10,720 --> 00:07:13,599
do you have any guesses

94
00:07:14,720 --> 00:07:17,840
three out of five a good one

95
00:07:18,560 --> 00:07:21,919
are you talking to me yeah

96
00:07:22,000 --> 00:07:28,800
now given that this is our first time cutting aluminum on our cnc

97
00:07:26,080 --> 00:07:33,280
one hand will be on the emergency stop the whole time

98
00:07:31,599 --> 00:07:36,720
our first piece didn't turn out perfectly but

99
00:07:34,880 --> 00:07:40,560
it gave us all of the critical dimensions that we needed and let us try

100
00:07:39,280 --> 00:07:45,919
out the new vice break we got from princess auto for like 60 bucks in

101
00:07:43,120 --> 00:07:51,360
theory this should bend our aluminum to a nice clean 90 degrees and give

102
00:07:48,639 --> 00:07:57,440
margaret a really solid chassis it's not quite as easy as a massive brake but it

103
00:07:54,160 --> 00:08:00,160
does seem to be working oh

104
00:07:57,440 --> 00:08:00,160
sounded good

105
00:08:06,800 --> 00:08:13,360
well it did mark it up a bit but

106
00:08:09,919 --> 00:08:15,840
given that that thing was like 60 bucks

107
00:08:13,360 --> 00:08:20,000
i can't really complain the prototype here is a solid proof of concept

108
00:08:18,160 --> 00:08:23,919
now there's just a bit of fine tuning and then we're good to make a final

109
00:08:21,520 --> 00:08:39,979
version really 60 bucks for a break that manage those those uh bends yeah dang

110
00:08:41,839 --> 00:08:48,560
this is problem hour with alex so you're about to watch a couple cnc

111
00:08:46,560 --> 00:08:51,040
router fails and they're a lot more off camera

112
00:08:49,600 --> 00:08:55,920
we tried a bunch of different things going faster going slower new bits and

113
00:08:54,399 --> 00:08:59,600
it turns out it was just a double-sided tape that we got

114
00:08:57,519 --> 00:09:02,640
it was not up for the task so

115
00:09:00,640 --> 00:09:08,440
we're going to be switching to the most accurate tool of all

116
00:09:04,880 --> 00:09:08,440
the angle grinder

117
00:09:08,480 --> 00:09:16,399
we'll need to make room for the radiator reservoir and cable management this will

118
00:09:13,600 --> 00:09:22,560
function just fine but gives up a lot of rigidity compared to the much thicker

119
00:09:18,399 --> 00:09:24,800
piece that we were going to see and see

120
00:09:22,560 --> 00:09:29,440
next the front of the case got chopped up to give the radiator more airflow and

121
00:09:27,200 --> 00:09:33,440
everything was filed down so that no hands would be cut while working in

122
00:09:31,600 --> 00:09:38,720
margaret with some radiator mounting holes added it was time to put the case

123
00:09:35,760 --> 00:09:42,399
back together riveting is a very simple way to get two pieces of sheet metal to

124
00:09:40,560 --> 00:09:46,880
stay together in a mostly permanent fashion

125
00:09:44,320 --> 00:09:50,480
not quite it's not in quite right select the correct size head for the

126
00:09:48,640 --> 00:09:54,800
rivet you're working with insert the rivet from the front line up the pieces

127
00:09:52,800 --> 00:09:59,200
you're about to rivet and squeeze your rivet gun until it pops

128
00:09:57,920 --> 00:10:03,680
repeat until your case is complete

129
00:10:01,200 --> 00:10:09,040
now it's time for some painting then we can finally get on to water

130
00:10:06,399 --> 00:10:12,880
cooling all right so the first coat of paint's on there

131
00:10:10,720 --> 00:10:17,200
and what i'm hoping we will do today is get everything

132
00:10:15,279 --> 00:10:20,240
pretty much mounted and water cooled then we'll take it all out put a second

133
00:10:18,800 --> 00:10:23,279
coat of paint on now that we know that everything's in the right spot

134
00:10:22,160 --> 00:10:28,399
and tomorrow we'll be done oh yeah

135
00:10:26,320 --> 00:10:34,160
for the water cooling hardware alphacool hooked us up with some primo stuff to

136
00:10:31,200 --> 00:10:37,040
make sure that margaret can shred or rip

137
00:10:35,040 --> 00:10:41,120
all the threads that we throw at her for our CPU we're using an ice block with a

138
00:10:39,440 --> 00:10:46,720
threadripper adapter then our rtx 2080 ti got an acetal water

139
00:10:45,120 --> 00:10:52,079
block for that sexy stealthy

140
00:10:48,640 --> 00:10:53,360
all blackened chromed look we swapped

141
00:10:52,079 --> 00:10:56,800
out the connection point to make vertical mounting easier

142
00:10:55,200 --> 00:11:04,079
so far so good but with the CPU and GPU in we realized that

143
00:11:01,200 --> 00:11:06,720
things didn't quite line up this is gonna be really freaking

144
00:11:05,519 --> 00:11:14,519
difficult it's starting to look kind of sexy though

145
00:11:10,320 --> 00:11:14,519
are you turned on by computers dennis

146
00:11:14,560 --> 00:11:20,800
huh now the key to getting a hard-line water

147
00:11:18,240 --> 00:11:25,680
cooling loop to work its best is to have as many things line up perfectly as

148
00:11:23,120 --> 00:11:31,279
possible this will make your runs a lot easier to complete with fewer fittings

149
00:11:28,480 --> 00:11:36,000
that means fewer points of failure now normally even for hardline bending

150
00:11:34,079 --> 00:11:41,360
the tubing is an option not with carbon fiber with that all in

151
00:11:38,720 --> 00:11:45,519
mind we created a bracket then to mount our pump with some room for adjustments

152
00:11:43,920 --> 00:11:50,079
after the fact there's just lots of mounting so everything's straight yeah no this is

153
00:11:48,320 --> 00:11:54,000
great well this isn't straight this isn't straight either

154
00:11:52,399 --> 00:11:58,640
i mean this can probably come yeah it can all be moved down a little yeah cool

155
00:11:57,120 --> 00:12:02,640
yeah i think it's gonna look really cool we're not using this color cables are we

156
00:12:00,720 --> 00:12:06,320
no that's just a stand-in hours are in the mail cool

157
00:12:04,160 --> 00:12:11,120
so for the tubing on this build we're going with carbon fiber it's gonna be a

158
00:12:08,560 --> 00:12:15,120
real big pain in the butt so carbon fiber if you like get the little

159
00:12:13,200 --> 00:12:18,880
bits that come off of it on you it'll make you all itchy if you get it in your

160
00:12:16,959 --> 00:12:21,279
mouth it's a really bad time if it goes into the air

161
00:12:20,399 --> 00:12:28,720
also like you get in your mouth your eyes really bad ppe aside carbon fiber tubing

162
00:12:26,320 --> 00:12:32,880
is pretty much like any other hardline tubing basically measure

163
00:12:30,959 --> 00:12:36,959
measure again cut

164
00:12:35,040 --> 00:12:41,279
sand and insert

165
00:12:39,040 --> 00:12:47,200
with that completed it was time to leak test i don't have a whole lot of

166
00:12:43,279 --> 00:12:48,480
confidence that this will not leak but

167
00:12:47,200 --> 00:12:52,560
oh well there's our first leak and our second

168
00:12:50,320 --> 00:12:55,040
leak and our third leak so we're having a couple of problems

169
00:12:53,839 --> 00:12:59,040
there the main one being that there are two o-rings in a fitting and we were

170
00:12:57,040 --> 00:13:03,360
only getting through the first one the second one the carbon fiber was just a

171
00:13:00,880 --> 00:13:06,800
bit too sharp even after being sanded so it either just hit it or when it went

172
00:13:05,440 --> 00:13:12,000
through it would just slice the o-ring to pieces and it wouldn't seal at all so

173
00:13:09,279 --> 00:13:17,680
to combat that we had to replace every single inner o-ring and lubricate it

174
00:13:14,320 --> 00:13:19,920
well for a nice clean insertion

175
00:13:17,680 --> 00:13:23,839
with the computer leak free it was time to take everything we'd done

176
00:13:21,839 --> 00:13:27,839
completely undo it take the whole thing apart and then put everything back in

177
00:13:26,480 --> 00:13:32,320
permanently now one of the biggest problems with

178
00:13:29,680 --> 00:13:37,120
this design is that there are a lot of things about our build that simply

179
00:13:34,320 --> 00:13:42,320
cannot be accessed once it's complete without disassembling the entire water

180
00:13:39,600 --> 00:13:47,200
cooling loop so it's important that we not forget anything at this stage

181
00:13:45,120 --> 00:13:52,639
like this laser cut acrylic cable hiding panel it's going to look really nice but

182
00:13:49,680 --> 00:13:55,360
once that's in those cables cannot come out

183
00:13:53,600 --> 00:13:59,600
other cosmetic things were done at this stage too like the drive bays which were

184
00:13:57,680 --> 00:14:04,639
unscrewed then epoxied into the front of the case to complete our vintage look

185
00:14:02,240 --> 00:14:10,160
now with everything slapped in and the loop topped off all that's left is the

186
00:14:07,600 --> 00:14:13,920
moment of truth error code 92 post error

187
00:14:15,040 --> 00:14:20,240
so just so i'm clear what you've been doing for the last two days is reseating

188
00:14:18,560 --> 00:14:26,160
the CPU yeah it didn't boot and then

189
00:14:23,279 --> 00:14:32,480
everything that's here had to come out in order to get the CPU i just took it

190
00:14:28,880 --> 00:14:33,920
out put it back in everything worked

191
00:14:32,480 --> 00:14:41,199
and also like we thought that it was other issues at first oh my god

192
00:14:38,399 --> 00:14:45,920
but hey the CPU is at 22 degrees now yep and it's cabled also wow you can

193
00:14:43,839 --> 00:14:50,160
really feel that airflow over the vents down here they are

194
00:14:47,600 --> 00:14:54,240
they are quite small for all the trials and tribulations that

195
00:14:52,320 --> 00:14:59,270
have come along with this i think this may be your finest sleeper

196
00:14:56,560 --> 00:15:03,210
yet

197
00:15:48,639 --> 00:15:51,639
no

198
00:17:30,960 --> 00:17:36,559
but margaret isn't just a pretty face

199
00:17:34,160 --> 00:17:42,960
she's a powerhouse that can compute circles around her sleeper siblings in

200
00:17:39,520 --> 00:17:46,400
certain workloads with zero tweaking she

201
00:17:42,960 --> 00:17:49,440
got a cinebench score of 5 5001

202
00:17:46,400 --> 00:17:51,919
and under full synthetic load on all 32

203
00:17:49,440 --> 00:17:57,039
cores even with the sub-optimal ventilation from the front our CPU

204
00:17:54,480 --> 00:18:03,840
reached a maximum temperature of 48 degrees after some tweaking we got a 4.1

205
00:18:00,240 --> 00:18:07,520
gigahertz overclock on all 32 cores

206
00:18:03,840 --> 00:18:10,400
netting us 6 000 points in cinebench and

207
00:18:07,520 --> 00:18:15,520
a blender bmw test time of just one minute 22 seconds

208
00:18:12,799 --> 00:18:20,559
to put that in context that is over four and a half times faster than a core i9

209
00:18:18,880 --> 00:18:25,120
macbook pro and then even with the overclock in

210
00:18:22,720 --> 00:18:31,200
longer tests margaret still didn't get any higher than 75 degrees on the CPU

211
00:18:28,320 --> 00:18:36,240
and as for gaming well margaret's rtx 2080 ti means that she can absolutely

212
00:18:33,679 --> 00:18:42,400
destroy games like you could fully expect to max out any aaa game at 1440p

213
00:18:40,000 --> 00:18:46,160
on a 144hz monitor so that's it big thanks to alex for

214
00:18:44,559 --> 00:18:49,360
sticking with this project it was an absolute nightmare because of some of

215
00:18:48,080 --> 00:18:52,960
the issues with uh well how large threadripper is and

216
00:18:51,520 --> 00:18:57,679
how you can kind of get inconsistent mounts in the socket sometimes and a big

217
00:18:54,960 --> 00:19:01,440
thanks to seasonic for sponsoring our efforts here even if you don't need the

218
00:18:59,840 --> 00:19:04,960
1300 watt beast of a unit that we put in our

219
00:19:03,280 --> 00:19:09,360
system you can be confident if you choose sea sonic that your power supply

220
00:19:07,200 --> 00:19:13,440
will last i tried to think of a bunch of other stuff to say about power supplies

221
00:19:11,120 --> 00:19:16,240
but like isn't that the bottom line and they've got a 12-year warranty to back

222
00:19:15,120 --> 00:19:20,720
