00:00:00,080 --> 00:00:07,680
Just about 20 years ago to the day, my wife Ivonne took me shopping for my

2
00:00:04,720 --> 00:00:11,759
birthday. My present, a window-mounted air conditioning unit that I promptly

3
00:00:09,920 --> 00:00:16,000
disassembled on the lawn so that I could chill my gaming CPU to sub-zero

4
00:00:13,920 --> 00:00:21,760
temperatures. She a keeper or what? Anyway, it's my birthday again, and this

5
00:00:18,480 --> 00:00:23,279
time I decided to spend a little more on

6
00:00:21,760 --> 00:00:25,920
my uh air conditioner. >> How much? >> 30.

7
00:00:25,199 --> 00:00:30,880
>> Oh, that's actually >> thousands. What? We already have

8
00:00:28,800 --> 00:00:35,520
numerous exotic coolers, including an industrial water chiller right there.

9
00:00:33,200 --> 00:00:40,320
Why did you spend $30,000 on this one? Because

10
00:00:37,040 --> 00:00:43,600
seeing this unique item handbuilt by

11
00:00:40,320 --> 00:00:46,000
overclocking legend Charles Fuggerworth

12
00:00:43,600 --> 00:00:49,600
is what inspired me to learn about Sub-Zero cooling in the first place,

13
00:00:47,840 --> 00:00:53,440
which is what led to my PC tuning obsession, which is what led to me

14
00:00:51,440 --> 00:00:58,480
standing here today. And you know what the craziest part is? His price for this

15
00:00:56,079 --> 00:01:04,080
thing, like literally the one that inspired me, isn't even unfair. While

16
00:01:01,760 --> 00:01:09,360
most chillers use a single compressor and refrigerant, this is a Cascade

17
00:01:07,040 --> 00:01:15,360
system and uses a total of three compressors, not to mention unobtanium

18
00:01:11,760 --> 00:01:17,600
gases to reach ungodly low temperatures.

19
00:01:15,360 --> 00:01:22,000
This very unit has been used to set countless performance records over the

20
00:01:19,200 --> 00:01:28,240
years, including live on stage at Intel launch events. And it comes with an

21
00:01:25,119 --> 00:01:31,040
extra special perk, hand delivery from

22
00:01:28,240 --> 00:01:35,360
the man himself, Charles, who flew up here to help me unbox it, verify that it

23
00:01:33,439 --> 00:01:40,880
works, and talk me through what makes his creation arguably the greatest CPU

24
00:01:39,119 --> 00:01:46,079
cooler on the planet. >> You got my money, right?

25
00:01:42,240 --> 00:01:48,479
>> Uh, no. But you know who does? Our

30
00:02:07,280 --> 00:02:14,239
>> I think some muscle to push on the screwdriver to strip them out.

31
00:02:12,319 --> 00:02:19,840
>> Uh, are you saying you don't think I have muscle? >> Yeah. What is it with everyone who's a

32
00:02:17,520 --> 00:02:23,520
guest on this channel and they just immediately open with the sick burns

33
00:02:22,080 --> 00:02:28,080
next? Are you going to ask me if I can reach all the way up there? >> I should get you a little stool.

34
00:02:26,239 --> 00:02:33,760
>> You're not even that much taller than me. I am so excited. I haven't even seen

35
00:02:31,360 --> 00:02:39,280
a picture of this thing since back when I was like browsing extreme systems.

36
00:02:35,840 --> 00:02:41,200
Now, I dreamed back then of

37
00:02:39,280 --> 00:02:46,160
commissioning you one day to build something like this for me. And I

38
00:02:43,040 --> 00:02:48,720
remember you did a handful of commission

39
00:02:46,160 --> 00:02:52,640
builds if I recall correctly, but like really a handful. How many of these have

40
00:02:51,280 --> 00:02:56,160
you actually built? >> 20 uh two stages. One, this is the only

41
00:02:55,040 --> 00:02:59,599
three stages I built. >> So you're saying this is a completely

42
00:02:58,319 --> 00:03:03,120
unique item then? >> Correct. Only a very few of these been

43
00:03:01,680 --> 00:03:08,080
attempted in the world. >> And what is the difference just for the

44
00:03:05,599 --> 00:03:12,239
uninitiated between a two- stage and a three-stage? Well, most of the two

45
00:03:09,680 --> 00:03:17,440
stages never really achieved 100 below zero Celsius. And as far as this one

46
00:03:15,680 --> 00:03:21,120
achieves 100 below zero, actually exceeds 100 below zero.

47
00:03:18,879 --> 00:03:25,120
>> I mean, architecturally, two stages versus three stages.

48
00:03:23,599 --> 00:03:30,879
What's the difference in the level of complexity having two compressors, one

49
00:03:28,000 --> 00:03:35,519
kind of cooling the first versus having three, one cooling the next one cooling

50
00:03:33,599 --> 00:03:39,200
the next one. the guesstimates getting the third stage gas well the optennium

51
00:03:37,360 --> 00:03:43,280
of the third stage gas first of all you can you can get like the poly cold or

52
00:03:41,360 --> 00:03:46,159
the revco units and you know try to work with one of those three-stage gases but

53
00:03:45,040 --> 00:03:50,560
you won't have the capacity you'll have to buy several of them or have to supplement the third stage gas and you

54
00:03:48,879 --> 00:03:54,799
won't have the capacity so if I wanted to build like a a sperm storage unit or

55
00:03:53,040 --> 00:03:59,519
something like that I could get like a nice low temperature

56
00:03:56,959 --> 00:04:04,000
right but if I want to cool something that is actively kicking out 500 600

57
00:04:02,959 --> 00:04:07,120
watts of need. >> Correct. Correct. Correct. >> I need this.

58
00:04:06,400 --> 00:04:12,560
>> Correct. Yes. >> This is the only one. >> Right. >> I got to tell you, I didn't realize how

59
00:04:11,360 --> 00:04:17,359
heavy it was. >> Yeah. >> Before we started, I gave it the old

60
00:04:14,640 --> 00:04:24,759
Okay. It couldn't be that. It's It's really freaking heavy.

61
00:04:20,239 --> 00:04:24,759
Literally, it's this or a vehicle.

62
00:04:25,040 --> 00:04:33,440
Everything about this thing screams

63
00:04:30,000 --> 00:04:34,960
handbuilt in the best possible way.

64
00:04:33,440 --> 00:04:41,440
>> When I originally built this, um, I didn't have very much refrigeration experience. So, I built all of my lines

65
00:04:39,199 --> 00:04:46,479
as the crow flies. Over many, many, many years, I perfected everything as I went.

66
00:04:43,520 --> 00:04:47,919
>> Now, you said that others have attempted three phases.

67
00:04:47,360 --> 00:04:54,639
>> Yes. >> Has anyone succeeded that you know of?

68
00:04:51,759 --> 00:04:59,600
No, not with the balance. Um, I've seen some other attempts, but

69
00:04:57,440 --> 00:05:03,400
I've never actually seen it in use. I'll get ready to catch it.

70
00:05:04,080 --> 00:05:11,280
>> Don't drop it on me. Hey. >> All right, I'll hold it.

71
00:05:07,680 --> 00:05:14,479
>> Thanks. You can hold 350 lbs, right?

72
00:05:11,280 --> 00:05:16,240
>> Oh, yeah. This is light work. Now, I

73
00:05:14,479 --> 00:05:19,600
couldn't help noticing, Charles, that my brand new purchase has some dust and

74
00:05:18,160 --> 00:05:23,039
rust on it. No, it doesn't. >> How long did you say this thing was?

75
00:05:21,280 --> 00:05:27,440
>> 25 years. 26 years. >> So, she's been around the block.

76
00:05:25,039 --> 00:05:30,240
>> Been around the world twice. Three times now. >> How would you rate this packing foam

77
00:05:29,120 --> 00:05:34,800
minus? >> Zero out of 10. >> Well, let's hope I got here in one

78
00:05:33,120 --> 00:05:38,560
shape. >> That's fine. When you're made it here,

79
00:05:36,560 --> 00:05:41,600
when it's when it's crate chipped like this, realistically, that's not doing

80
00:05:40,240 --> 00:05:47,520
anything. It's just sitting on top of it. >> I'm just having fun at work.

81
00:05:44,560 --> 00:05:50,639
>> I know. I'm sorry. Sorry, sir. >> That's better.

82
00:05:50,720 --> 00:05:57,000
I'm waiting for the camera to stop rolling. Keep it rolling so you can't hit me while it's rolling.

83
00:05:58,479 --> 00:06:03,280
>> Sorry. How many power cords? >> Three.

84
00:06:01,600 --> 00:06:07,120
>> How much power does this thing draw? >> 45 amps at max.

85
00:06:05,600 --> 00:06:10,720
>> Over 5,000 watts. >> Could be. >> What do you What What do you mean could

86
00:06:10,160 --> 00:06:16,319
be? >> So, why does it need to draw 5,000 watts when it's only cooling 500 watts?

87
00:06:14,880 --> 00:06:21,039
>> Yeah, >> professor, explain that.

88
00:06:20,000 --> 00:06:25,039
I didn't want to I didn't want to undershoot. That's okay.

89
00:06:23,360 --> 00:06:29,919
>> Okay. But but in all seriousness, there are efficiency losses. Yes. Especially

90
00:06:27,680 --> 00:06:35,759
as we make our way through multiple stages. So like our main stage, our

91
00:06:33,360 --> 00:06:41,199
biggest one that cools the second that in turn cools the third has to be

92
00:06:38,160 --> 00:06:43,280
absolutely enormous, monstrous overkill

93
00:06:41,199 --> 00:06:46,639
from from my understanding. Mhm. >> Um well, here let's get it up on the

94
00:06:44,960 --> 00:06:50,560
table and then maybe you can walk us through

95
00:06:48,319 --> 00:06:54,400
where all the gases flow. >> Okay. >> In order to make it work its magic.

96
00:06:52,880 --> 00:06:57,199
Here. I just want to get this under it. So maybe we can get some fingers under

97
00:06:55,919 --> 00:07:03,520
it so we can maybe lift it. >> Oh god. I don't want to get fingers under that. >> Oh wow. You really don't because Charles

98
00:07:01,440 --> 00:07:07,440
in his infinite wisdom built it with sharp corners.

99
00:07:05,599 --> 00:07:10,960
>> It's designed that way. So you get a nice clean cut.

100
00:07:09,039 --> 00:07:13,919
>> If if it's a if it's a poor cut, it's hard to attach. Again, >> you want to take it off right at the

101
00:07:13,520 --> 00:07:18,560
segment. >> No, it's just for this the stitches go clean.

102
00:07:17,440 --> 00:07:21,599
>> Are we doing okay? >> You're doing great. >> Let's get Lionus's end on first.

103
00:07:21,120 --> 00:07:24,880
>> Uhhuh. >> Cuz he's by himself. >> Yep.

104
00:07:24,319 --> 00:07:28,319
>> I'm good. >> You're good. Yeah. No, I'm good. >> Okay. Put your in a corner down and then

105
00:07:27,599 --> 00:07:33,520
>> Okay. >> My fingers are now being squished. But that is okay.

106
00:07:30,880 --> 00:07:38,639
>> Uh do you need help? >> What?

107
00:07:34,639 --> 00:07:42,400
>> My fingers were stuck. It's good.

108
00:07:38,639 --> 00:07:44,240
>> Okay. There's stuff that you get to see.

109
00:07:42,400 --> 00:07:49,280
>> I'm glad you're here to tell me how it works. I found the three compressors and

110
00:07:47,039 --> 00:07:54,720
I found the the cold end that goes on the CPU. I found what looks like a K

111
00:07:52,960 --> 00:07:58,720
probe or something like that probe. >> Perfect. So, that's going to tell us

112
00:07:56,479 --> 00:08:02,879
what the temperature is at our evap head. I'm going to need you to kind of

113
00:08:00,800 --> 00:08:07,680
walk me through it. So, where's our first stage? >> This is our first stage compressor. This

114
00:08:05,120 --> 00:08:10,960
is a Danfos SC12 MLX low temp compressor. It's basically a half horse

115
00:08:09,520 --> 00:08:15,360
compressor. So basically this is for sub-zero temperatures and uh it has

116
00:08:13,199 --> 00:08:19,120
R507. It's a common gas that you can use for uh refrigeration. So this gets about

117
00:08:17,680 --> 00:08:22,560
40 below zero. Okay. >> And it uh runs into our heat exchanger

118
00:08:20,960 --> 00:08:27,280
back here which is a lightron brace plate heat exchanger 40 plate.

119
00:08:24,000 --> 00:08:30,000
>> Okay. So then normally right you would

120
00:08:27,280 --> 00:08:34,479
have uh you know your condenser side which is where you have your fans and

121
00:08:32,080 --> 00:08:38,479
your you know aluminum fins or whatever right and then you would have your

122
00:08:36,080 --> 00:08:42,640
evaporator side which would in the case of like an air conditioner more aluminum

123
00:08:40,800 --> 00:08:47,920
fins and a fan that blows the cold air into the room for you to enjoy or in the

124
00:08:45,200 --> 00:08:52,000
case of a refrigerant-based CPU cooler it would go to the evaporator head which

125
00:08:50,160 --> 00:08:56,240
would go to your CPU but we're not doing that >> because this is a multi-stage stage,

126
00:08:54,399 --> 00:09:00,959
we're taking our cold side, our evaporator side, and we're going to a

127
00:08:58,399 --> 00:09:04,560
heat exchanger. So then that means this inside here is the cold side of stage

128
00:09:03,680 --> 00:09:08,000
one >> and the hot side of stage two,

129
00:09:07,360 --> 00:09:15,680
>> right? >> So that refrigerant, which for stage two

130
00:09:11,200 --> 00:09:16,560
starts at -40C, right on the hot side.

131
00:09:15,680 --> 00:09:21,600
Okay, where does that go? >> Well, the hot side goes into the called it's called a duper heater first before

132
00:09:20,080 --> 00:09:25,360
it before it even goes to the heat exchanger. So, I'm actually stripping off the heat before it goes into the

133
00:09:24,480 --> 00:09:28,880
heat exchanger. >> Oh. To make it easier for our first

134
00:09:27,600 --> 00:09:32,720
stage to cool it. >> Condense. Correct. >> God. >> So, I'm bringing it down to ambient.

135
00:09:31,600 --> 00:09:37,360
>> So, we precool it. >> Correct. >> Brilliant. So, where does it go from

136
00:09:36,640 --> 00:09:41,200
there? >> It actually goes into the expansion valve

137
00:09:39,839 --> 00:09:44,640
>> and it goes into the second stage compressor. There's an expansion valve on this side. This is a pressure

138
00:09:43,600 --> 00:09:48,720
expansion valve. Yeah. >> And it's u has a little knob on the side

139
00:09:47,040 --> 00:09:53,040
over here that you can adjust. And >> Oh, I won't. >> No, no, don't don't have to. It's

140
00:09:50,560 --> 00:09:56,560
already preset. Oh, good. And then what? I don't see another heat exchanger.

141
00:09:55,120 --> 00:10:01,760
>> Oh, it's all built. It's all inside of here. >> Oh, so you're telling me then that we

142
00:09:59,600 --> 00:10:05,200
actually have two heat exchangers in here. >> Correct.

143
00:10:02,800 --> 00:10:08,320
>> One that is using the first stage to chill the hot side of the second stage

144
00:10:07,200 --> 00:10:14,000
to minus 40. >> Correct. >> And then one that's using the cold side

145
00:10:11,040 --> 00:10:17,680
of the second stage. - 80, you said? >> Yes.

146
00:10:14,640 --> 00:10:22,240
>> To cool the hot side of the third stage.

147
00:10:17,680 --> 00:10:24,399
>> Yes. which is at -80 C. Now, this my

148
00:10:22,240 --> 00:10:29,519
understanding goes is where kind of the black magic and the tuning and the

149
00:10:26,560 --> 00:10:34,240
unobtanium gases really come into play. >> Correct. Condensing the third stage gas.

150
00:10:31,519 --> 00:10:40,079
>> Okay. So, I did notice that our third stage compressor, which is this guy over

151
00:10:36,480 --> 00:10:41,200
here, looks a little gruntier.

152
00:10:40,079 --> 00:10:46,000
>> No, it's exactly the same. They're all the same compressor. >> Wait, it looks bigger.

153
00:10:43,200 --> 00:10:50,100
>> No, it's all the exact same. Okay, I need to use whatever trick it's using

154
00:10:47,440 --> 00:10:50,430
with my wife.

155
00:10:52,800 --> 00:10:58,560
I did notice there are a few components that we haven't talked about much. Okay,

156
00:10:56,720 --> 00:11:03,279
>> we didn't mention the oil separators. >> Correct. >> What's their role in this system?

157
00:11:00,959 --> 00:11:07,360
>> Uh to keep the oil separated from the system. Um because when we're working at

158
00:11:05,120 --> 00:11:12,320
temperatures that are sub-zero and when you get the the the oil inside the

159
00:11:09,440 --> 00:11:16,240
lines, it can call flogging and that'll cause the system to fail. And you don't

160
00:11:15,360 --> 00:11:21,920
want the system to fail. >> No, I don't. >> One of the major problems that I had with my cascade was uh system volume.

161
00:11:20,399 --> 00:11:26,560
And one of the early things I did with the create system volume was I cur I

162
00:11:23,760 --> 00:11:30,880
pigtailed my line trying to think that I was adding volume to my system by adding

163
00:11:29,200 --> 00:11:34,880
>> making them a helix kind of like you do on the traces of a PCB to make sure that

164
00:11:33,120 --> 00:11:37,839
you know all the traces to the memory slots are the same length for instance

165
00:11:36,640 --> 00:11:42,480
>> right but I was trying to add volume to the system by adding more length of the

166
00:11:40,160 --> 00:11:47,120
thing but I wasn't very knowledgeable at the time but in time I realized I could

167
00:11:45,040 --> 00:11:52,240
get suction accumulators and add more volume to the system and so what these

168
00:11:49,279 --> 00:11:56,800
do is These are like right before the the line set and they add more volume to

169
00:11:55,440 --> 00:12:01,839
the system >> these are just a giant reservoir

170
00:11:59,600 --> 00:12:05,360
essentially of refrigerant gas >> correct >> wrap my brain around this one and this

171
00:12:03,839 --> 00:12:10,959
time I don't actually know the answer before I'm asking you

172
00:12:07,680 --> 00:12:13,600
>> how does having a large volume of the

173
00:12:10,959 --> 00:12:18,560
gas that isn't actively participating in being cooled

174
00:12:15,920 --> 00:12:22,399
as far as I can tell it's not insulated how does that help Oh boy. Oh boy. Oh

175
00:12:20,480 --> 00:12:26,240
boy. I don't know how to explain this that you guys can understand it.

176
00:12:25,680 --> 00:12:29,440
>> Um >> damn.

177
00:12:28,720 --> 00:12:35,680
>> Damn. >> Let me let me I always had um capacity

178
00:12:32,880 --> 00:12:40,560
issues and I always had to like add more gas to the system and I had a problem

179
00:12:37,839 --> 00:12:44,720
with adding more gas and then having the pressures on the system too high. So in

180
00:12:43,040 --> 00:12:49,920
order for me to add more gas and not have the this the pressures too high, I

181
00:12:47,760 --> 00:12:53,680
had to add more had to increase the volume. And so by adding the suction

182
00:12:52,000 --> 00:12:58,000
accumulator solve that problem. >> So it's almost like like like buffering

183
00:12:55,839 --> 00:13:00,560
you against pressure volatility in a sense like what what is it? What role is

184
00:13:00,000 --> 00:13:06,560
it playing? >> More gas. Um I need more gas to go to the block.

185
00:13:04,160 --> 00:13:10,720
>> Okay. But if the gas isn't actively >> more liquid I needed more liquid to go

186
00:13:07,839 --> 00:13:18,800
to the block. So it gives you just more fluid overall because liquid is so much

187
00:13:15,200 --> 00:13:20,639
denser than gas. But then when you, you

188
00:13:18,800 --> 00:13:23,279
know, weren't running it, the pressure would be astronomical because it's all

189
00:13:22,079 --> 00:13:26,880
in its gaseous form. >> Right. >> Well, I had I had to put more gas in the

190
00:13:25,839 --> 00:13:31,920
system and the pressure would go up higher and then I can't run into like a

191
00:13:29,360 --> 00:13:36,959
>> Understood. So this just gives us enough. So, so realistically when we're

192
00:13:34,000 --> 00:13:42,160
running this is not like high density gas storage at that time because so much

193
00:13:39,680 --> 00:13:44,320
of it is in liquid form but this gives it somewhere to go.

194
00:13:43,360 --> 00:13:48,240
>> Yes. >> All becomes gas right. >> Okay, I think we got it.

195
00:13:47,279 --> 00:13:53,519
>> Yes. >> See, I could understand that. >> Yeah, great explanation.

196
00:13:51,600 --> 00:13:56,320
>> There is one thing we missed. >> Yes.

197
00:13:54,959 --> 00:13:59,519
>> Do I need to be paying attention to these? Like if these go to the red line,

198
00:13:58,079 --> 00:14:03,199
do I freak out and pull all the plugs out? Like >> No, no, no. These just let me know like

199
00:14:01,920 --> 00:14:08,560
if the second stage and the first stage are running. So if I my my pressures go

200
00:14:05,360 --> 00:14:10,480
up I can pull this pull the plugs. Um

201
00:14:08,560 --> 00:14:13,519
basically when we shipped it I could you know like when you took the picture I

202
00:14:11,680 --> 00:14:18,639
can know if the the gas is leaked or not. >> Um in future like I can always like we

203
00:14:16,800 --> 00:14:21,680
can mark the the pressures right now and like a year from now we can see if we

204
00:14:19,920 --> 00:14:26,160
lose pressure and we can you know charge the system. >> Right. But not the third stage. I mean

205
00:14:24,240 --> 00:14:30,560
do do you have a bottle of the third stage? >> No.

206
00:14:28,480 --> 00:14:35,279
>> Sure. Yeah. Yeah. Yeah. Yeah. No, >> it's kind of making it sound like

207
00:14:32,560 --> 00:14:37,680
there's a bit of a like fire up procedure for this.

208
00:14:36,320 --> 00:14:40,959
>> Correct. There is a procedure for firing up. C >> Can we do it?

209
00:14:40,079 --> 00:14:44,240
>> You want to fire it up? >> I mean, yeah. >> Okay. Uh, do we pull some cords? We can

210
00:14:43,839 --> 00:14:48,720
fire it up. >> All right. So, this is going to take about 10 minutes to to come down.

211
00:14:47,279 --> 00:14:54,160
>> Well, are these labeled? >> Uh, no. I just No, but we'll we'll label

212
00:14:50,880 --> 00:14:55,680
them before we go.

213
00:14:54,160 --> 00:14:59,760
>> What should I be monitoring here? I mean, obviously I can see some of my

214
00:14:57,519 --> 00:15:02,560
fluid flowing through here. Am I Am I looking at pressures? How do I know when

215
00:15:01,440 --> 00:15:06,480
it's down to temperature? >> Okay. So, right now, uh we just got to wait a few minutes and we're going to

216
00:15:05,120 --> 00:15:10,959
watch for some ice build up on the first stage. The ice will build up right here on the on the back side of the uh the

217
00:15:10,079 --> 00:15:15,199
suction line. >> Okay. >> And so once we get a little bit of ice built up on there, we can fire up the

218
00:15:13,760 --> 00:15:18,320
second stage compressor. And we watch for the same thing on the second stage compressor. We watch for a little bit of

219
00:15:17,279 --> 00:15:24,880
ice building up on the back of the second stage compressor. >> Now, riddle me this. If someone were to

220
00:15:22,240 --> 00:15:29,040
irresponsibly fire the second stage compressor when we are not cooling the

221
00:15:27,519 --> 00:15:33,600
first stage, what happens? >> I don't know. Never done that.

222
00:15:31,360 --> 00:15:35,360
>> Neat. Now, let's say I don't like learning things the hard way,

223
00:15:35,040 --> 00:15:41,519
>> right? >> Where are the do not touch, no touchy places? >> Uh, this would be one of them.

224
00:15:39,839 --> 00:15:43,839
>> Oh, there's a thing that was burned on there. >> Yes. This would also be one of them.

225
00:15:43,519 --> 00:15:48,079
>> Yes. >> And this would also be one of them. >> Okay. >> That's the only three spots that are

226
00:15:46,959 --> 00:15:52,959
that are >> danger zones. >> Oh, look at that. Hey, we're frosting.

227
00:15:50,800 --> 00:15:55,920
Now, should I care about that at all? Like, like it'll drip and rust.

228
00:15:54,639 --> 00:15:59,040
>> No, no, no. Once I fire up the second stage, that'll evaporate. >> And I assume the second stage is the

229
00:15:58,560 --> 00:16:03,360
middle one. >> Yep. >> Good assumption. All right, >> go for it.

230
00:16:01,680 --> 00:16:06,480
>> Okay. It's a little bit not quite straight, but hey,

231
00:16:05,360 --> 00:16:10,320
>> aren't we all Okay, >> so when I plug in this third stage, this

232
00:16:08,480 --> 00:16:16,560
one, actually, this one's going to drop. >> Yeah. >> And then about about 15 or 20 seconds

233
00:16:14,399 --> 00:16:21,199
later, this is going to start to drop. Oh, the temperature at the evap head for

234
00:16:19,199 --> 00:16:23,120
the third stage. And this is where we cool our CPU.

235
00:16:22,320 --> 00:16:27,759
>> Okay, there we go. >> Big moment. Here we go. >> It's not that flat, Charles.

236
00:16:27,040 --> 00:16:31,199
>> What do you mean? >> I just mean, you know, the quality of the

237
00:16:30,320 --> 00:16:36,880
>> It's perfectly flat. >> The quality of the workmanship is just, you know, it's uh

238
00:16:34,399 --> 00:16:42,959
>> subzero. In all seriousness, when you have this

239
00:16:39,519 --> 00:16:45,920
level of cold up against the CPU, the

240
00:16:42,959 --> 00:16:50,000
macro flatness of the surface does still matter. You don't want like a big bump

241
00:16:48,399 --> 00:16:54,399
coming out of it that's giving you bad contact. But little pock marks like

242
00:16:52,320 --> 00:16:58,000
that, they don't actually matter though. >> You might want to resurface it.

243
00:16:56,000 --> 00:17:01,600
>> Oh, wo. She's really going now. >> So, it'll stop around90 until we put a

244
00:16:59,839 --> 00:17:06,559
load on it. >> 90. So, you're saying it goes lower when

245
00:17:04,559 --> 00:17:09,439
we put a load on it? Yeah, this is a thermal expansion valve on this side

246
00:17:08,000 --> 00:17:15,120
here. The more load we put on it, the the more it'll open the valve. >> You're at 69, baby.

247
00:17:12,000 --> 00:17:16,959
>> Oh, buddy. It It started sublimating.

248
00:17:15,120 --> 00:17:20,400
So, you're saying if I licked it, that would be bad. >> Your tongue would stick to it instantly.

249
00:17:19,679 --> 00:17:26,959
>> Oh, that's so >> You would be Yeah, we have to You'd be going to the hospital.

250
00:17:24,400 --> 00:17:30,559
>> What are we at? 90gative 83. >> Oh, we still got a ways to go.

251
00:17:28,240 --> 00:17:34,799
>> Oh, okay. Oh, okay. So, we would wait until she's completely down to 90 before

252
00:17:32,880 --> 00:17:41,240
we put a load on her or doesn't matter. It will just expansion valve and then

253
00:17:36,799 --> 00:17:41,240
Yeah. Wow.

254
00:17:41,600 --> 00:17:46,240
Woo. It's snowing, boys.

255
00:17:44,720 --> 00:17:53,360
>> So, when this is bolted to the CPU and the CPU is put under full load, this will drop about 1 or 2°, maybe even 3°.

256
00:17:50,080 --> 00:17:56,080
>> And another critical thing that is so

257
00:17:53,360 --> 00:18:02,640
cool about this system is that it won't go up. So our temperature stability

258
00:17:59,600 --> 00:18:05,679
compared to basically any other solution

259
00:18:02,640 --> 00:18:07,200
is unheard of. Like even when you're

260
00:18:05,679 --> 00:18:11,600
dealing with liquid nitrogen for instance, one of the big hassles of

261
00:18:09,280 --> 00:18:16,320
overclocking with LN2 is that you are constantly micromanaging the liquid

262
00:18:14,240 --> 00:18:22,160
nitrogen in your pots because you don't actually want your CPU necessarily at

263
00:18:18,640 --> 00:18:23,520
negative 150°. That can be problematic.

264
00:18:22,160 --> 00:18:29,440
You can run into cold bugs. So you got to like you got to bring it up in order to boot. You got to put it back down

265
00:18:27,039 --> 00:18:32,799
when it's time to do your run. With this system, we're just

266
00:18:32,320 --> 00:18:39,440
>> exact >> at minus 90 all the time. Idle, load,

267
00:18:37,200 --> 00:18:42,160
doesn't matter. No no micromanagement.

268
00:18:40,640 --> 00:18:46,400
>> One thing I have to uh don't have to deal with is crashing a lot. So, once

269
00:18:44,000 --> 00:18:49,919
we're stable, we're good to go for the a full bench session. We can bench for 16

270
00:18:48,080 --> 00:18:53,679
hours straight and like crash once or twice. >> Okay. Now, it's going to be a separate

271
00:18:52,320 --> 00:18:58,799
video, but can we tease them a little bit? Can you show us one of these golden

272
00:18:56,240 --> 00:19:03,280
chips which okay have been rumored for many years to exist? It's been rumored

273
00:19:00,480 --> 00:19:08,320
that reviewers get golden samples hand selected by Intel. That's We

274
00:19:05,440 --> 00:19:14,000
don't. He does. Can I see one? >> Sure. Sure.

275
00:19:09,039 --> 00:19:15,919
>> Well, it looks like any other 1400 KS.

276
00:19:14,000 --> 00:19:19,919
How do you know it's special? >> It's probably been like one of

277
00:19:17,840 --> 00:19:23,919
>> some number. Now, when you have a chip of this quality, I don't think it's a

278
00:19:22,080 --> 00:19:28,880
big secret that Intel has had some degradation challenges with their 13th

279
00:19:26,240 --> 00:19:33,280
and 14th gen silicon. Do you kind of do the early testing with your sacrificial

280
00:19:30,799 --> 00:19:35,440
lambs and then save your best chip for like when it's time to break the record?

281
00:19:34,880 --> 00:19:43,200
>> Yes. >> Okay. I guess my only last question then

282
00:19:38,720 --> 00:19:44,799
is why on earth are you selling this?

283
00:19:43,200 --> 00:19:50,880
>> I'm going to build another. I already started. Oh, so actually I'm kind of

284
00:19:48,320 --> 00:19:54,320
funding V2 then in a way. Are you are you using the the proceeds to to fund

285
00:19:53,600 --> 00:19:58,880
the next one? >> Yes. >> All right. Is the second one going to be

286
00:19:57,120 --> 00:20:01,440
so much better that I'm going to feel like I need a new one?

287
00:20:00,320 --> 00:20:06,160
>> Um you're going to have to tell me because it's going to be yours.

288
00:20:05,360 --> 00:20:10,720
>> Wait, what? >> Yeah, I'm building you a second one. I know. I haven't told you yet, but uh I

289
00:20:09,120 --> 00:20:15,280
had to break it to you somehow. >> You are? Do you know about this? No.

290
00:20:13,280 --> 00:20:18,480
>> Does anybody know about this? Really? >> Oh, we're we're building you a second

291
00:20:18,160 --> 00:20:24,720
one. >> When was this decided? >> I thought we were building you a second one.

292
00:20:22,160 --> 00:20:29,120
>> Yeah. Oh, not a three-stage, though. >> Oh, okay. No, we're building we'll build

293
00:20:26,720 --> 00:20:33,200
we'll build you a single stage, I guess. >> What? >> It just needs another $30,000.

294
00:20:31,120 --> 00:20:36,240
>> Oh, yeah. Oh. Oh. Oh, yeah. Okay. No, no, but >> No, no, I'm sorry. Okay.

295
00:20:35,679 --> 00:20:43,280
>> Hold on. What's >> We'll build We'll just build you a single stage. >> Oh, we're talking about that, right?

296
00:20:40,880 --> 00:20:47,840
>> A custom single stage. Exotic single stage. No, we actually have a couple

297
00:20:45,200 --> 00:20:52,480
more things coming. So, this is setting up a whole series with Charles. We're

298
00:20:50,080 --> 00:20:57,760
doing the unboxing here. Part two, we're going to set some world records. Part

299
00:20:54,320 --> 00:21:01,760
three, I'm going to do an everyday

300
00:20:57,760 --> 00:21:02,799
Subzero CPU and GPU build for home.

301
00:21:01,760 --> 00:21:05,600
That's what you're talking about. >> Yeah. And plus, I'm going to And plus, I'm going to build another three-stage

302
00:21:05,360 --> 00:21:10,320
myself >> for yourself. >> Most likely. Most likely. Most likely I'm going to build a two-stage. I'm

303
00:21:08,880 --> 00:21:15,039
happy to be part of the journey no matter what you build next because I

304
00:21:12,400 --> 00:21:19,600
just love seeing enthusiasts go out of their comfort zone and just do cool like

305
00:21:17,200 --> 00:21:23,600
this. It has been such a pleasure to have you here and uh it's going to be

306
00:21:21,919 --> 00:21:27,440
such a pleasure to continue to have you here as we work our way through all the

307
00:21:25,280 --> 00:21:31,200
incredible Sub-Zero adventures we have planned. >> Well, thank you for helping me out on my

308
00:21:29,280 --> 00:21:34,000
journey and uh your proceeds will definitely go towards another build and

309
00:21:32,799 --> 00:21:39,919
I'll make sure it's better than this one. >> And you know what else is going to be better than this one? some future segue

310
00:21:38,880 --> 00:21:43,840
to our sponsor, >> War Thunder. Unleash your destructive

311
00:21:42,000 --> 00:21:49,360
side by getting behind the controls of over 2500 aircraft armored vehicles and

312
00:21:46,720 --> 00:21:54,240
warships. With over 70 million players registered, each battle will feel

313
00:21:51,120 --> 00:21:56,080
immense, intense, and unique. Speaking

314
00:21:54,240 --> 00:22:00,159
of unique, each vehicle model is painstakingly reimagined after their

315
00:21:58,320 --> 00:22:03,120
real life counterparts, down to the fuel tanks, engines, and any other

316
00:22:01,679 --> 00:22:07,520
components, all of which can individually take damage. And with their

317
00:22:05,200 --> 00:22:11,039
X-ray view, you can see exactly where shots land and what ultimately led to

318
00:22:09,440 --> 00:22:14,400
the destruction of a vehicle. If all that sounds like a little bit too much

319
00:22:12,480 --> 00:22:17,919
battle sim for you, don't worry. There's a ton of different game modes available

320
00:22:16,080 --> 00:22:21,679
so you can hop right into the action, whether you're just a casual gamer or if

that I got to play around with refrigerant cooling with the LD PCV10, I

325
00:22:36,720 --> 00:22:44,000
think it was from Little Devil. It was a PC case that had a single stage CPU

326
00:22:41,600 --> 00:22:49,120
