1
00:00:00,240 --> 00:00:06,319
this is the million dooll PC a very

2
00:00:04,040 --> 00:00:10,800
expensive collection of servers that are linked together with an incredible piece

3
00:00:08,360 --> 00:00:14,679
of software called WCA that allows them to act like one giant storage server

4
00:00:13,440 --> 00:00:20,800
with the ability to reach speeds measured in the 100s of gigabytes per

5
00:00:17,600 --> 00:00:25,320
second watch this

6
00:00:20,800 --> 00:00:28,039
and damn boy wa a second that's a little

7
00:00:25,320 --> 00:00:33,719
faster than it used to be that's because the million dooll PC has

8
00:00:30,480 --> 00:00:37,399
glowed up a little bit we've scaled from

9
00:00:33,719 --> 00:00:41,440
six to nine storage machines giving us a

10
00:00:37,399 --> 00:00:44,879
whopping 2.2 pedabytes of raw kokia

11
00:00:41,440 --> 00:00:46,879
powered PCIe Gen 4 storage it's almost

12
00:00:44,879 --> 00:00:53,039
as much storage as we have on hard drives in our mother Vault but orders of

13
00:00:49,800 --> 00:00:55,399
magnitude faster which means it's also

14
00:00:53,039 --> 00:01:00,680
really power hungry which means it's also really hot even with 3 tons of air

15
00:00:58,800 --> 00:01:05,840
conditioning in here it's still 40 flipping de which is terrible for

16
00:01:03,160 --> 00:01:10,119
hardware and terrible for any humans who need to work in here now we could add

17
00:01:08,000 --> 00:01:15,320
more air conditioning but that would be even more expensive than this already is

18
00:01:13,000 --> 00:01:21,880
you know what's not expensive the not one but six APC Tower coolers that we

19
00:01:19,439 --> 00:01:27,400
inherited for free from a local data center that's right folks we are doing

20
00:01:24,360 --> 00:01:30,200
whole server room water cooling and this

21
00:01:27,400 --> 00:01:33,040
time I swear we are going to do it right so where are the plumbers well we're not

22
00:01:31,960 --> 00:01:37,680
we're not really doing it right today we'll do it right later that's fine

23
00:01:35,560 --> 00:01:42,240
right we're just going to DIY that is not what I had in mind when I sold this

24
00:01:39,360 --> 00:01:46,600
to our sponsor build Redux they make it easy to get into the world of PC gaming

25
00:01:44,520 --> 00:01:50,680
just pick your games see the performance and the pros at build Redux will build

26
00:01:48,320 --> 00:01:55,320
the PC for you visit build Redux at the link down below now under normal

27
00:01:53,000 --> 00:01:59,640
circumstances you would run chilled water in the unit in your data center

28
00:01:57,719 --> 00:02:04,600
and use that chilled water to cool the air but chilling the water costs money

29
00:02:02,240 --> 00:02:10,560
and that's what we're trying to avoid right so since we also spend money

30
00:02:08,319 --> 00:02:15,160
heating our warehouse and we have so many of these things kicking around

31
00:02:12,080 --> 00:02:18,000
anyway we were thinking why not cool the

32
00:02:15,160 --> 00:02:22,000
server room and heat the warehouse in the winter turning this one into less of

33
00:02:19,519 --> 00:02:26,840
a cooling tower and more of a heating Tower yeah it was designed for that

34
00:02:24,319 --> 00:02:31,800
right I mean this should work great like in theory this is a mint plan in

35
00:02:30,000 --> 00:02:36,160
practice well I guess we're about to find out yeah in practice we have a

36
00:02:34,000 --> 00:02:42,920
giant cooling tower on a forklift on a not storage rated uh

37
00:02:38,959 --> 00:02:44,280
mezzanine water's not heavy 3 2 1 oh

38
00:02:42,920 --> 00:02:50,360
okay yeah that feels great where do we want it exactly in

39
00:02:47,120 --> 00:02:52,800
theory it blows hot out that side mhm so

40
00:02:50,360 --> 00:02:56,360
probably pointing that way sure that might not be intuitive because this is

41
00:02:54,760 --> 00:03:01,400
obviously the front of the unit so you would think that's where it draws air in

42
00:02:59,080 --> 00:03:06,200
but in a data center deployment these cooling towers sit in between the

43
00:03:03,360 --> 00:03:11,239
servers and servers will typically pull cold air in from the cold aisle in front

44
00:03:08,519 --> 00:03:16,840
of them and then heat up the air and blow it out the back so by having these

45
00:03:13,640 --> 00:03:19,280
towers in between your servers what

46
00:03:16,840 --> 00:03:24,200
happens is that hot air comes out gets sucked into the cooling tower and then

47
00:03:21,799 --> 00:03:28,920
gets blown through this Radiator in the middle blown out the front and sucked

48
00:03:26,640 --> 00:03:32,840
back into the server let's put it in the corner pointing that way Hey Jake yeah

49
00:03:31,280 --> 00:03:36,799
what I figured out what one of the things we thought might be a temp probe

50
00:03:34,720 --> 00:03:40,560
before is what it must have gotten jostled loose at some point but these

51
00:03:38,799 --> 00:03:44,000
guys right here they have little floats on them oh they're the like the water

52
00:03:41,920 --> 00:03:47,000
level they're for an excess condensation meter yeah when you're running chilled

53
00:03:45,640 --> 00:03:50,920
water through them they can start to condensate pretty aggressively we're not

54
00:03:48,840 --> 00:03:55,480
doing that so it should be fine yeah I saw the drip trays before and I also saw

55
00:03:52,959 --> 00:03:59,840
that there was rust everywhere in the bottom of the units but I didn't realize

56
00:03:57,239 --> 00:04:03,239
that that was by Design as cool as it is is though that this unit is more intact

57
00:04:01,480 --> 00:04:07,799
it also means that we haven't modified the fittings yet so well you did such a

58
00:04:05,400 --> 00:04:12,760
great job last time so uh you want to have a chance to try to do such a great

59
00:04:09,280 --> 00:04:15,400
job too oh okay boom Uno

60
00:04:12,760 --> 00:04:18,440
reverse see you later before we solder on those fittings I want to give you

61
00:04:16,400 --> 00:04:23,240
guys a bit of a background the tubing inside the unit is 1 in which is a

62
00:04:20,799 --> 00:04:29,919
pretty standard size which is nice um except what I found out getting 1in

63
00:04:26,400 --> 00:04:31,759
tubing it's not that common and also all

64
00:04:29,919 --> 00:04:36,479
of the fittings are very expensive and since this is like our DIY approach even

65
00:04:34,880 --> 00:04:40,520
though my original plan was to use garden hoses uh I found out garden hoses

66
00:04:38,560 --> 00:04:43,680
are really expensive so we might as well use the stuff we're going to use in the

67
00:04:42,160 --> 00:04:47,840
long term and since we're going to have to take it down anyways we're going to

68
00:04:45,479 --> 00:04:51,800
use shark bites and shark bites are really cool they're basically like you

69
00:04:49,560 --> 00:04:56,440
push the tubing in and that's all you do it's now a fixed it's warrantied for 25

70
00:04:53,919 --> 00:05:01,199
years it's it's sick they're just really really

71
00:04:58,479 --> 00:05:03,720
expensive that's smells delicious it was taking too

72
00:05:05,000 --> 00:05:11,800
long one and a two you got to make sure it's

73
00:05:10,240 --> 00:05:15,680
clean before you solder otherwise the solder doesn't stick at least that's

74
00:05:13,600 --> 00:05:18,960
what Plumbing tick Tok told me naturally this is going to be what you'd call a

75
00:05:16,919 --> 00:05:22,840
closed loop system meaning it's filled with a certain amount of water and

76
00:05:20,199 --> 00:05:26,280
closed off but only to a point when you have Radiant Heating in your house for

77
00:05:24,479 --> 00:05:32,199
instance there is some amount of evaporative loss so you fill the coolant

78
00:05:28,720 --> 00:05:33,440
up and over time slowly you lose some of

79
00:05:32,199 --> 00:05:38,440
it the way that they get around that is by using a check valve that's basically just hooked up to your House's water

80
00:05:36,240 --> 00:05:42,280
pressure which automatically as some evaporates a little bit comes into fill

81
00:05:40,720 --> 00:05:47,520
I didn't really want to do that because I want to do it today and I'm not a plumber but fortunately our mechanical

82
00:05:45,440 --> 00:05:51,880
room is right below us and it has a hose bib so we were like why don't we just

83
00:05:49,800 --> 00:05:54,400
hook the hose bib up to the tank but then if you just turn it on the Tank's

84
00:05:53,080 --> 00:06:00,840
going to overflow and explode and whatever it's like how can we fill a

85
00:05:56,680 --> 00:06:02,720
tank I could like design a custom system

86
00:06:00,840 --> 00:06:05,840
or I could just buy a toilet fill valve we have this tank from McMaster Car

87
00:06:04,199 --> 00:06:09,360
which we're going to add fittings to with these fancy bulkhead fittings but

88
00:06:07,639 --> 00:06:13,120
in the meantime this has got to come out the bottom which means we need to drill

89
00:06:11,000 --> 00:06:13,120
a

90
00:06:15,639 --> 00:06:23,599
hole it just knew the job was done I bet you this stuff is tasty there's Supply

91
00:06:20,160 --> 00:06:26,360
sparingly oh oops we're putting the

92
00:06:23,599 --> 00:06:30,720
threaded ones on here we'll solder those and then twist the female shark bites on

93
00:06:29,599 --> 00:06:38,240
and then the tubing can just go like that in theory a she's mint

94
00:06:35,840 --> 00:06:41,479
Bud it occurs to me we never tested this thing I mean we have spare parts it

95
00:06:39,919 --> 00:06:46,680
would probably be faster just to pull another one up here right Jamie oh yeah

96
00:06:43,720 --> 00:06:53,440
absolutely luckily there just so happens to be the exact plug we need right here

97
00:06:50,520 --> 00:06:56,560
20 amp 120 volt we got some adapters and extension cords from infinite cables

98
00:06:54,880 --> 00:07:02,720
thanks guys pluggy plug hey you hear that

99
00:07:01,080 --> 00:07:08,039
that's the condensation pump running at the start that's not too loud right sounds

100
00:07:06,560 --> 00:07:11,560
great it's actually not that heavy when there's nothing in it as he struggles to

101
00:07:10,199 --> 00:07:14,280
move it what's the worst that could happen I drop the

102
00:07:16,000 --> 00:07:21,840
thing mint let's go over this one more time pump right below the reservoir that

103
00:07:20,400 --> 00:07:26,800
way it gets fed directly we had a problem trying to Prime in at Linus's house with the pool trying to avoid that

104
00:07:25,039 --> 00:07:31,440
then it will go down to the cooler come all the way back up blah blah blah into

105
00:07:28,440 --> 00:07:33,199
our heater what I'm calling it and then

106
00:07:31,440 --> 00:07:36,599
out the heater into a filter before the reservoir so we catch all the gunk

107
00:07:34,520 --> 00:07:42,440
before the reservoir reservoir back to the pump and the Vicious Cycle continues

108
00:07:39,919 --> 00:07:46,560
cool are we expecting a lot of Gunk no I feel like we should have also filtered

109
00:07:44,080 --> 00:07:51,199
the water coming in we'll put a valve down here so that

110
00:07:49,240 --> 00:07:54,800
when the water comes in well at the start we can close this and the water

111
00:07:53,759 --> 00:07:59,199
will go into the reservoir which will make it easier to bleed then once the

112
00:07:56,840 --> 00:08:01,240
system is running we just open this valve

113
00:08:00,039 --> 00:08:05,520
and most of the water will just go directly into the pump and kind of ignore the reservoir when it's coming

114
00:08:03,840 --> 00:08:09,199
back up here that way we don't have like the full force of the pump just like

115
00:08:07,599 --> 00:08:12,720
gushing into the reservoir constantly making a bunch of noise I wish we had

116
00:08:10,840 --> 00:08:17,919
like straps this Mak this much easier unless we use the LT Cable Management

117
00:08:14,800 --> 00:08:19,039
things to this metal pipe oh hell yeah

118
00:08:17,919 --> 00:08:23,039
the reason that we're putting valves here and actually at every piece is a so

119
00:08:21,240 --> 00:08:26,560
we can service a piece individually you shut off the valves and then we can take

120
00:08:24,479 --> 00:08:30,120
it out and swap it or change it or replace it whatever we're doing and B

121
00:08:28,960 --> 00:08:36,399
because it's like like I said before this is all going to get redone properly and I want it to be easy for him to just

122
00:08:33,279 --> 00:08:40,159
take apart whoa it's like it's designed

123
00:08:36,399 --> 00:08:41,959
for dude it's mint male a te and a valve

124
00:08:40,159 --> 00:08:45,959
and a valve yeah this isn't going to leak no it's going to be great they're

125
00:08:43,760 --> 00:08:51,720
shark bites sick before we had this Grand idea

126
00:08:49,120 --> 00:08:56,120
of water cooling the server room we tried to mitigate this problem by adding

127
00:08:53,720 --> 00:09:01,120
a duct and a fan which was pretty easy to do because right where we are right

128
00:08:57,800 --> 00:09:03,160
here is about 10 ft from the server room

129
00:09:01,120 --> 00:09:07,680
and there's just a hallway so we added like this insulated duct between and a

130
00:09:04,959 --> 00:09:11,160
big fan and it did help but ultimately once it gets up to equilibrium it wasn't

131
00:09:11,279 --> 00:09:18,480
enough hey it's through oh that wasn't

132
00:09:14,600 --> 00:09:20,440
even that hard huh huh mint we forgot

133
00:09:18,480 --> 00:09:25,399
about the filter I realized Alex is putting this all together I'm like oh yeah where are we putting the filter

134
00:09:22,320 --> 00:09:25,399
damn it right where Alex is

135
00:09:26,360 --> 00:09:34,440
working oh no brother brother did they

136
00:09:30,040 --> 00:09:38,839
sell me the mother oh my God why

137
00:09:34,440 --> 00:09:38,839
didn't I check this no filter it

138
00:09:39,880 --> 00:09:45,839
is since a long-term plan is to rip the RADS out of these giant units and just

139
00:09:44,480 --> 00:09:50,279
stick it right on the back of the rack so it captures the heat directly uh I

140
00:09:48,640 --> 00:09:56,079
don't care that much about where this goes since it's probably only going to be here for a couple months later so

141
00:09:54,920 --> 00:10:02,160
we're thinking we just leave it up against the back here that way the hot air comes out get get sucked in on the

142
00:10:00,399 --> 00:10:06,959
back and shoots out cool air in the front and because of that we're thinking

143
00:10:04,560 --> 00:10:14,320
we just leave the back door off and then I can just pull this tubing kind

144
00:10:10,360 --> 00:10:17,680
of right in there beautiful look at that

145
00:10:14,320 --> 00:10:19,399
that's mint good job Alex I'm excited to

146
00:10:17,680 --> 00:10:25,920
see if it leaks or not the great thing is we won't know until it's far too late

147
00:10:21,880 --> 00:10:27,519
on the bottom side yeah oh shut it off

148
00:10:25,920 --> 00:10:31,040
here's the problem we're running into this tank is thick down the middle

149
00:10:29,320 --> 00:10:35,920
Middle where the seam is and when this is sitting in here it looks good like

150
00:10:33,440 --> 00:10:40,399
that except when you tighten it down that extra material pushes it out on an

151
00:10:38,320 --> 00:10:44,880
angle and now the seals can't seal I walk back into this project and I'm

152
00:10:42,120 --> 00:10:48,360
immediately told well it leaked um oh who whoa whoa be careful there's

153
00:10:46,040 --> 00:10:53,920
fittings on the bottom but we have a fix for the leak and it's glue no not that

154
00:10:51,480 --> 00:11:00,720
not that it's the the ooo this stuff is like $40 a tube it

155
00:10:57,639 --> 00:11:02,639
does not leak it's a nice non hardening

156
00:11:00,720 --> 00:11:07,639
so it stays kind of plasticky and goopy solution silicone yeah I wasn't able to

157
00:11:05,120 --> 00:11:11,760
do it exactly how I was hoping because it's still kind of cockeyed but I don't

158
00:11:10,279 --> 00:11:15,880
think it's going to leak I put I put a lot in there but I have a job for you

159
00:11:13,760 --> 00:11:19,800
cool I uh spent some of your money and got the wrong thing so we have to do it

160
00:11:17,519 --> 00:11:23,519
again if I had a dollar for every time he said that wasn't I would be able to

161
00:11:21,839 --> 00:11:28,000
afford all these mistakes what are we building uh a filter housing they sold

162
00:11:25,600 --> 00:11:31,360
me the wrong size of PVC even though I was like I just need to connect these

163
00:11:30,079 --> 00:11:37,440
two things and they were like okay we're going to give you one inch PVC because it's one inch well it's supposed to be

164
00:11:34,760 --> 00:11:41,240
inch and a quarter cool uh so I have 20t of 1in PVC that I have no use for and

165
00:11:39,160 --> 00:11:44,560
then we went to the store they were like okay we could we can tell you this it'll

166
00:11:42,959 --> 00:11:49,320
probably be long enough so you have to cut the threads off and then cut it in

167
00:11:46,959 --> 00:11:54,839
half and hopefully that is like enough oh man

168
00:11:52,360 --> 00:12:00,120
that's going to be uh you have one shot at this don't screw it up and this is my

169
00:11:58,040 --> 00:12:04,880
saw yeah look this is what the professionals told us to buy they might

170
00:12:02,680 --> 00:12:11,040
have told us the wrong thing last time but here we are again surely that

171
00:12:07,120 --> 00:12:11,040
wouldn't happen twice no got the

172
00:12:12,959 --> 00:12:19,079
clamps not really what this is for but it's working I cut off part of the

173
00:12:16,839 --> 00:12:23,880
threads I sanded down the little nubbins now they fit in here which is why I was

174
00:12:20,760 --> 00:12:25,279
doing that by the way really uh oh wait

175
00:12:23,880 --> 00:12:29,600
oh balls we have to cut this down the middle too okay well um I have to go do

176
00:12:28,040 --> 00:12:33,320
a conference call so what I mean you only got one thing done and so you

177
00:12:31,199 --> 00:12:36,920
didn't even get it done I don't know if you're getting your minutely bonus

178
00:12:35,320 --> 00:12:39,600
minutely

179
00:12:39,600 --> 00:12:46,160
bonus look at that worky oh nice yeah I

180
00:12:44,120 --> 00:12:52,720
didn't know that this glue set up in 10 minutes there's your filter perfect

181
00:12:49,120 --> 00:12:54,680
um damn it I looked in the manual for

182
00:12:52,720 --> 00:13:00,560
the cooling tower things and I did randomly stumble upon uh them mentioning

183
00:12:57,600 --> 00:13:05,600
a filter and they said a 20 mesh and I think this is 100 so it's a lot finer

184
00:13:03,560 --> 00:13:09,040
should be fine as long as our pump has enough power for it it doesn't really

185
00:13:06,680 --> 00:13:13,120
matter it I mean it's not that fine yeah also it's still it's still like a mint

186
00:13:10,760 --> 00:13:16,880
for 1in tubing so it should be fine now we just have to find out where we can

187
00:13:14,519 --> 00:13:20,760
put it now we just have to pose with it like not everyone's a poser don't

188
00:13:19,240 --> 00:13:24,199
worry can you walk me through what's going on here a little bit because I

189
00:13:22,720 --> 00:13:29,360
missed the part where you guys drilled holes in the building we've got the cooling tower over there we've got the

190
00:13:27,079 --> 00:13:32,839
tubes coming off of that and we already have the tubes in the server room

191
00:13:30,360 --> 00:13:37,079
already hooked up we had previously cut a hole for our ducting solution so we

192
00:13:35,480 --> 00:13:41,800
just stuffed the tubes down the duct that goes through the like hallway there

193
00:13:38,639 --> 00:13:44,279
into the Ser oh wow and these awesome

194
00:13:41,800 --> 00:13:50,160
Cable Management things the magnet is so strong that it just it's kind of

195
00:13:47,639 --> 00:13:56,040
perfect in terms of pump this is not our end game this is like a cast iron pump

196
00:13:52,240 --> 00:13:57,680
and we're using oxyard tubing which it

197
00:13:56,040 --> 00:14:00,959
limits the amount of oxygen it's probably f look your house is probably

198
00:13:59,440 --> 00:14:07,160
the same cast iron pump in it for like 20 years and it's fine but it isn't the

199
00:14:04,079 --> 00:14:09,120
end game I picked up a stainless version

200
00:14:07,160 --> 00:14:11,759
of the one step up from this pump this one I think does around 20 gallons per

201
00:14:10,680 --> 00:14:16,600
minute and the big boy that we're getting does around 40 wow which is a

202
00:14:15,079 --> 00:14:20,839
lot of gallons a lot of gallons per minute okay are we ready to hook this up

203
00:14:19,079 --> 00:14:26,240
in theory yeah I mean let's do it we tried before so let's try again hold on

204
00:14:24,759 --> 00:14:30,040
before you do that that tube is plugged into the wrong thing on the top of that

205
00:14:28,399 --> 00:14:35,360
oh did you guys anything right on the first attempt or that is a excellent

206
00:14:32,920 --> 00:14:38,600
question and we decided to not Mount the filter up

207
00:14:36,399 --> 00:14:42,680
there he always chirps me for doing things like kind of the easy way and

208
00:14:40,800 --> 00:14:45,440
then fixing it later and he's literally just like purposely doing that right now

209
00:14:44,399 --> 00:14:50,120
well we're just not going to fix it later it's fine I'm going to fix it later what no don't waste time on that

210
00:14:48,560 --> 00:14:55,079
it's fine well you I'm not the one that wasted time don't move it it doesn't

211
00:14:52,240 --> 00:14:58,639
matter you told me it doesn't matter I'm going to send you a video of me moving

212
00:14:56,680 --> 00:15:01,480
it later no that is going to be a huge waste of time cuz you'll have to

213
00:14:59,920 --> 00:15:05,839
disconnect the tubes in order to you could have just fixed it right now let's

214
00:15:03,240 --> 00:15:09,800
put the tubes in come on I'm coming back here with a rotary tool I'm actually

215
00:15:08,240 --> 00:15:13,440
going to shave off the tops of these screws let's give ourselves a little bit

216
00:15:11,759 --> 00:15:17,440
of breathing a lot of breathing room that's fine I like to breathe a lot we

217
00:15:15,440 --> 00:15:23,399
we know I plan to keep doing

218
00:15:21,240 --> 00:15:27,240
it easy peasy by the way I found an easier way to do this just take the

219
00:15:25,040 --> 00:15:30,279
white thing out first oh okay okay this is bothering me do you hear that now is

220
00:15:29,319 --> 00:15:36,720
everyone hearing that I don't know what you're talking about every just said it's bothering me editor's note cut out

221
00:15:34,199 --> 00:15:42,720
this entire story line okay it's on the wall filtered what I dropped one of the

222
00:15:40,440 --> 00:15:47,519
little shark bite white thingies and it fell down the hole hey

223
00:15:44,519 --> 00:15:50,000
lonus no you

224
00:15:47,519 --> 00:15:56,800
suck oh my God Jake did you turn the water on no why is it wet I don't

225
00:15:53,639 --> 00:15:59,279
know where's the water shut off is this

226
00:15:56,800 --> 00:16:03,319
valve broken I I was dumping water down the hole oh

227
00:16:01,480 --> 00:16:06,839
my God you suck do you want me to turn the water on okay that actually does

228
00:16:05,079 --> 00:16:12,319
pour down into an electrical box so you really shouldn't do that oh what really

229
00:16:08,920 --> 00:16:15,680
uh yeah I I honestly have no idea where

230
00:16:12,319 --> 00:16:15,680
the shark bite thing went

231
00:16:17,839 --> 00:16:25,600
taada what oh she's on no it's in it's

232
00:16:23,160 --> 00:16:30,720
in somebody needs to go in the server room and watch okay in case that leaks

233
00:16:28,959 --> 00:16:34,000
because if that starts leaking it's going to be a while before it all stops

234
00:16:32,880 --> 00:16:37,000
leaking ooh

235
00:16:37,120 --> 00:16:43,120
dick ah a dick I get it no stop you a

236
00:16:41,399 --> 00:16:47,839
his first is my loging in high school was a. dick okay and then you want it

237
00:16:45,079 --> 00:16:53,160
one click apparently right 7/8 inch ballcock let's turn this thing on yeah

238
00:16:50,079 --> 00:16:55,560
go for it see you later okay it's on I I

239
00:16:53,160 --> 00:16:59,360
got water coming that's good do it full send let's go I can't believe this tank

240
00:16:58,279 --> 00:17:06,280
is not leak are you ready Mr Dick I ready it's

241
00:17:03,480 --> 00:17:10,199
coming whoa it sell fills how's it looking why didn't we do this at my

242
00:17:07,640 --> 00:17:15,120
house this is awesome no idea it's actually great you know V2

243
00:17:12,640 --> 00:17:22,480
right is it fine yeah like everything's fine down there Jake we have a leak oh

244
00:17:17,559 --> 00:17:24,760
God uh where uh on on the uh the return

245
00:17:22,480 --> 00:17:29,000
fitting no we got it we got it I got it I tell you guys standing right at the

246
00:17:26,480 --> 00:17:31,360
back of the air output of these servers it's

247
00:17:32,679 --> 00:17:39,960
exhausting Alex Alex Alex he may be a

248
00:17:36,760 --> 00:17:42,679
dick but he's our dick this is the

249
00:17:39,960 --> 00:17:48,360
world's slowest leak at this point ready one more and nice note that every

250
00:17:46,120 --> 00:17:51,720
fitting I did is not leaking this is the one you did I didn't do that one yeah

251
00:17:50,480 --> 00:17:56,919
you did you stuck the tote I don't know what you're talking about we managed to fix our leaks I replaced the fittings

252
00:17:55,360 --> 00:18:00,520
down here on both sides I think we just used Too Much Teflon tape uh the first

253
00:17:59,200 --> 00:18:04,799
time we hooked it up and it kind of just like bunged up the threads and then

254
00:18:02,600 --> 00:18:08,120
upstairs I just cut the PEX sanded it down stuck it back in and everything's

255
00:18:06,240 --> 00:18:10,760
good no more leaks now I've got the million dollar PC hooked up and running

256
00:18:09,559 --> 00:18:14,840
again and I want to test something before Linus gets here uh one of the big

257
00:18:13,039 --> 00:18:19,320
things you want to do in a setup like this especially if you were doing this

258
00:18:16,360 --> 00:18:22,880
in a data center is contain the hot air so we're going to make ourselves a

259
00:18:20,640 --> 00:18:29,280
little bit of a hot aisle with some cardboard right now it says 31 is De on

260
00:18:26,480 --> 00:18:33,960
the intake maybe it's 31.1 31.2 let's see if it goes up any Higher by

261
00:18:31,880 --> 00:18:38,360
just adding the cardboard I want to just kind of proof of concept before I spend

262
00:18:35,919 --> 00:18:42,679
the time doing a better job of this obviously still a giant Gap here but

263
00:18:40,120 --> 00:18:50,200
let's see if it makes a difference oh 31.3 31.4 it's going

264
00:18:47,320 --> 00:18:53,360
up5 6 okay maybe it's only like half a degree but half a degree is important

265
00:18:52,039 --> 00:18:57,280
because the whole game here is temperature differential the larger we

266
00:18:55,440 --> 00:19:01,880
can make the difference in temperature on this side to the temperature out in

267
00:18:59,600 --> 00:19:05,159
the warehouse the better this system will work hey that's not

268
00:19:05,559 --> 00:19:12,880
bad we have our hot aisle which is going through the cooler and the rest of the

269
00:19:10,000 --> 00:19:16,200
server room is our cold aisle it's not a perfect science but it's better than

270
00:19:14,600 --> 00:19:21,760
when it was open oh oh god look I wanted optimal

271
00:19:19,679 --> 00:19:26,799
circumstances for our very scientific test it's definitely hot how do you like

272
00:19:23,919 --> 00:19:30,280
it I have so many questions that's great it's hot in here hey it's really hot hot

273
00:19:28,919 --> 00:19:35,159
in here but would you believe me if I told you the air conditioning's off

274
00:19:32,480 --> 00:19:42,400
really it's 32° in here don't get me wrong it is hot but the AC is off off

275
00:19:39,360 --> 00:19:45,159
and this has been running for like hours

276
00:19:42,400 --> 00:19:50,520
that's actually kind of cool so look at the UPS we're drawing 4.95 Kow except no

277
00:19:48,760 --> 00:19:55,840
we're not half of these servers are hooked up to the Main's power so we're

278
00:19:53,200 --> 00:20:02,880
probably drawing more like probably like 8 to 10 Kow however the can we turn the

279
00:19:59,679 --> 00:20:05,919
AC on yes aren't we going to be taking

280
00:20:02,880 --> 00:20:07,120
cold air that's been heated up a little

281
00:20:05,919 --> 00:20:11,280
and running it through our heat exchanger potentially cooling the

282
00:20:09,559 --> 00:20:15,880
warehouse look I don't know if it's going to get that cold uh I don't know

283
00:20:13,760 --> 00:20:19,880
if you've stood Behind these things at all they're hot it's quite hot the exit

284
00:20:18,159 --> 00:20:24,440
temperature of these servers is probably like 40° even with air condition air

285
00:20:22,799 --> 00:20:30,360
coming through it but you are right it will be colder that being said before

286
00:20:28,240 --> 00:20:34,280
when these actually running with just the air conditioning it was 40° in here

287
00:20:32,679 --> 00:20:39,520
I think we should turn that off and see how hot it gets in here okay cuz it's

288
00:20:36,919 --> 00:20:42,640
been 32 for over an hour this is a cool software called check MK it's a

289
00:20:40,880 --> 00:20:47,799
monitoring tool that's open source very awesome we've hooked up the systems with

290
00:20:45,480 --> 00:20:54,919
SNMP which is a monitoring protocol and you can see the coolant coming in is 28°

291
00:20:52,320 --> 00:21:00,720
from coming from the warehouse yes after it's been cooled with air that's around

292
00:20:57,320 --> 00:21:03,840
21° and then and leaving here it's 32°

293
00:21:00,720 --> 00:21:05,840
that's a 4° difference that's a lot of

294
00:21:03,840 --> 00:21:10,520
heat it doesn't sound like a crazy number but at the fluid flow rate that

295
00:21:07,919 --> 00:21:15,360
we've got that's a freak ton of heat yeah clearly we have a problem of it not

296
00:21:13,039 --> 00:21:18,600
quite getting cooled over there as much but I had a brilliant idea we have six

297
00:21:17,320 --> 00:21:24,240
of the bloody things let's just put another up there we could why not or

298
00:21:21,480 --> 00:21:27,720
hear me out we bury a coil in the parking lot oh I'm totally down for that

299
00:21:26,080 --> 00:21:31,640
give me the approval I will find a contractor today that is not that's

300
00:21:30,120 --> 00:21:38,000
above my pay grade these days oh I got to ask paren yes hi Money free cooling

301
00:21:35,640 --> 00:21:41,600
lus said it was a good idea anyway yeah we could throw another one up there for

302
00:21:39,440 --> 00:21:47,440
sure like pretty easily we just actually need two T's that's it interestingly too

303
00:21:44,000 --> 00:21:48,919
the return versus Supply Air is a 3°

304
00:21:47,440 --> 00:21:54,720
difference right now so the air coming into the back is almost 40° 37 and then

305
00:21:52,360 --> 00:22:00,640
the air coming out of the front is 33.6 they are still going up a bit but like I

306
00:21:57,320 --> 00:22:02,159
said it's been at 30 2 for an hour uh I

307
00:22:00,640 --> 00:22:07,039
imagine if we left this overnight we probably come back and it might be like

308
00:22:03,840 --> 00:22:08,799
34 or 35 in here but considering we're

309
00:22:07,039 --> 00:22:12,960
not air conditioning this at all let's see what happens if we turn it off oh

310
00:22:10,799 --> 00:22:15,679
God I don't think the air conditioning is going to make that much of a

311
00:22:14,120 --> 00:22:19,880
difference in terms of the air coming out of here the metal on the back of

312
00:22:17,919 --> 00:22:25,240
this rack is up to 46° the air coming out of the back of

313
00:22:22,159 --> 00:22:30,080
this power supply is as high as

314
00:22:25,240 --> 00:22:31,919
60° oh 76 it's uh 33 .2 now this may not

315
00:22:30,080 --> 00:22:38,520
be safe for this hardware for much longer it's 33.3 now it's gone up a full

316
00:22:36,080 --> 00:22:42,880
degree in like 3 minutes it's getting warmer

317
00:22:40,320 --> 00:22:47,159
34.1 I'm getting quite uncomfortable I think what I want to see now is if the

318
00:22:44,960 --> 00:22:50,520
air conditioner can actually work cooperatively with the heat exchanger to

319
00:22:49,159 --> 00:22:55,559
get it down to like normal temperature in here yeah okay all right let's do it

320
00:22:53,159 --> 00:23:00,360
so our Baseline is when we started this project it was hitting about 40° in here

321
00:22:58,080 --> 00:23:05,000
with just the air conditioner running if we can beat that it means that somehow

322
00:23:03,080 --> 00:23:10,000
through the magic of thermodynamics they are working together 34 and2 plug the

323
00:23:07,520 --> 00:23:16,440
goddamn thing back in a sweet relief so our Peak was

324
00:23:13,720 --> 00:23:19,520
42 with the AC off and now it's come down

325
00:23:17,600 --> 00:23:26,200
to 37 37.8 and up here is equally as mint

326
00:23:23,679 --> 00:23:30,400
you like my sound ding yeah I mean it'll do something not much in this config

327
00:23:28,919 --> 00:23:35,320
that's what I was going for is something something long term we get sheet of

328
00:23:32,760 --> 00:23:39,240
plywood and attach the rock wall on the inside of it to kind of make a baffle if

329
00:23:37,559 --> 00:23:43,480
I stand here it's pretty loud but if I go behind this

330
00:23:41,240 --> 00:23:49,200
thing it's a pretty substantial difference we just have to create kind

331
00:23:46,000 --> 00:23:51,960
of a a sound blocking maze that air can

332
00:23:49,200 --> 00:23:56,720
move through but um block sound from reaching people below us and it's also

333
00:23:54,039 --> 00:24:00,880
at like 80% fan right now if we put a second one up here and run them like

334
00:23:58,960 --> 00:24:05,320
half the speed should be tolerable all right wait we should look at the filter

335
00:24:03,240 --> 00:24:12,200
oh is there shoo in there not too bad and we're back so not as good as it was

336
00:24:08,960 --> 00:24:15,440
before no it says 1.8 th000 Watts on the

337
00:24:12,200 --> 00:24:17,120
readout which oh no which is a lot given

338
00:24:15,440 --> 00:24:24,279
the amount of power that we're putting into it what one pump in some fans huh

339
00:24:21,480 --> 00:24:29,320
22° in here right now Supply versus return air is still like a Delta of more

340
00:24:26,880 --> 00:24:34,480
than 2° that's solid and interestingly the cooling

341
00:24:31,240 --> 00:24:37,840
temperature is lower but what I realized

342
00:24:34,480 --> 00:24:39,520
look at this the fan speed is lower oh

343
00:24:37,840 --> 00:24:44,880
what I also realized after looking at this is that there's a valve I remember

344
00:24:42,440 --> 00:24:48,240
when you guys did the thread R cooling there's a manual valve right that's like

345
00:24:46,480 --> 00:24:52,159
the bypass valve and you guys were like oh you're supposed to close it so it doesn't bypass actually you're supposed

346
00:24:50,480 --> 00:24:56,520
to leave it open because there's a mixing valve in the unit for your

347
00:24:54,760 --> 00:25:01,200
application actually probably just shut it doesn't matter but the thing can

348
00:24:59,080 --> 00:25:05,760
dynamically adjust how much water goes through the radiator and how much gets

349
00:25:02,799 --> 00:25:11,159
bypassed I think to maintain to maintain a Delta ideal temperature yeah it's

350
00:25:09,159 --> 00:25:15,600
totally fine in here now it's working I'm surprised it works this well well

351
00:25:13,559 --> 00:25:19,799
the ducting was key but the other big thing is I think that we were just on

352
00:25:17,200 --> 00:25:24,559
the edge of this air conditioning unit's capacity so just taking the edge off

353
00:25:22,559 --> 00:25:28,320
taking another thousand couple thousand Watts out of here and what's cool is

354
00:25:26,600 --> 00:25:32,880
because we've got it hooked up direct directly to the exhaust from this rack

355
00:25:30,720 --> 00:25:36,880
adding more to this rack is going to increase that Inlet air temperature

356
00:25:35,240 --> 00:25:42,240
which increases the efficiency of the thermal transfer of our heat exchanger

357
00:25:39,799 --> 00:25:47,919
mission accomplished yeah I'm actually kind of shocked I mean 2° cut off the

358
00:25:45,360 --> 00:25:51,640
exhaust temp doesn't sound like a lot but that's like already outside of the

359
00:25:49,600 --> 00:25:55,679
server and we're talking 2° and a lot of air oh I can't wait for part two it's

360
00:25:54,039 --> 00:25:59,080
going be so much better when this is directly on the rack I'm thinking we put

361
00:25:57,360 --> 00:26:03,159
two on the mezzanine for like winter time but we could also put one like

362
00:26:00,880 --> 00:26:06,360
outside somewhere we could have valves and we could decide where we want to

363
00:26:04,720 --> 00:26:10,240
dump heat from this room we could automate them pretty easily too we got

364
00:26:08,200 --> 00:26:14,159
have electric Valves and a couple temp sensors and a Ras pie so we can send the

365
00:26:12,600 --> 00:26:18,200
heat outside when it's hot in the warehouse and send it inside when we

366
00:26:16,120 --> 00:26:22,880
want to heat the warehouse yeah and interestingly we could put it in that

367
00:26:20,399 --> 00:26:26,559
mechanical room and just like cut a hole in the one put a big thing yep it's our

368
00:26:25,200 --> 00:26:32,399
mechanical one yeah what's the landlord going to do about it screw that guy and screw the segue to our sponsor

369
00:26:30,039 --> 00:26:36,320

00:27:21,559 --> 00:27:27,919
enjoyed this video why not check out the time we did this at home with radiators

382
00:27:25,279 --> 00:27:31,240
from PT Cruisers oh yeah yeah this would have worked a lot better yeah but those

383
00:27:29,520 --> 00:27:35,880
work pretty good you could just take one of these home no they work great I'm not

384
00:27:33,799 --> 00:27:39,600
changing anything oh yeah okay ducting I could duct to the PT Cruiser radiators

385
00:27:37,880 --> 00:27:44,919
but that's all I would change oh my God we're getting that elu like 1 M by 1 m x

386
00:27:42,399 --> 00:27:49,120
1 M 3D printer and we have a 3D scanner they could 3D scan the back of your rack

387
00:27:46,840 --> 00:27:52,720
and make like a a duct shroud look he's actually like considering it right now

388
00:27:51,039 --> 00:27:56,519
you were thinking cardboard but we could do it in here oh yeah totally cuz we

389
00:27:54,240 --> 00:28:01,000
could take the AC straight to the front of this rack we want some over here too

390
00:27:58,880 --> 00:28:05,760
I guess if the ambient is low enough it's probably fine it'll be fine yeah

391
00:28:02,760 --> 00:28:05,760
okay
