00:00:00,240 --> 00:00:06,960
karen's graphics card was running at like 100 degrees idle while water cooled

2
00:00:04,720 --> 00:00:10,559
but the water still has to run through this

3
00:00:08,080 --> 00:00:15,839
graphics card and see how terrible it is can you see the floater right there

4
00:00:12,480 --> 00:00:18,640
it moves around if you tip the card

5
00:00:15,839 --> 00:00:23,680
the metal touched my skin but the problem that i have right now is

6
00:00:21,199 --> 00:00:28,000
the plan was to just remove the graphics card from the loop put another graphics

7
00:00:25,600 --> 00:00:31,760
card in there and then have the loop go through this non-powered graphics card

8
00:00:30,400 --> 00:00:36,000
which would hopefully not add any temperature to the loop and then it would be fine but i don't even want to

9
00:00:34,239 --> 00:00:39,800
run this computer on the full loop if it's this gunked up

10
00:00:45,760 --> 00:00:51,760
Corsair delivers real mech or oh here i have one huh real mac or nothing with

11
00:00:50,239 --> 00:00:56,800
their new strafe mechanical keyboard featuring genuine german-made cherry mx

13
00:00:56,800 --> 00:01:03,920
more i'm gonna move my chin now just a three for a loop

14
00:01:00,320 --> 00:01:07,920
at last my friends it is finally

15
00:01:03,920 --> 00:01:10,400
finally here the conclusion of the whole

16
00:01:07,920 --> 00:01:15,520
room water cooling system series of videos that we have waited

17
00:01:12,479 --> 00:01:18,479
over a year since initially putting

18
00:01:15,520 --> 00:01:23,680
these systems together to finally talk about whether or not the concept worked

19
00:01:21,520 --> 00:01:27,920
whether or not in practice it actually worked and the wait is over only a

20
00:01:26,479 --> 00:01:31,840
couple more minutes it kind of reminds me of that uh that bmw video that i was

21
00:01:30,240 --> 00:01:35,200
teasing on social media not that long ago about the all-new one series drop a

22
00:01:33,840 --> 00:01:41,439
like on the bottom of the video if you want to see us finally release that because i think we're very close

23
00:01:38,799 --> 00:01:44,640
let's go so i want to do a recap of the concept for those who haven't been

24
00:01:43,040 --> 00:01:50,000
following along the whole time our editing den is in a south-facing room of

25
00:01:48,159 --> 00:01:55,119
the house that we have been running Linus media group out of for the last

26
00:01:51,680 --> 00:01:56,159
year and a half and it gets

27
00:01:55,119 --> 00:01:59,600
friggin hot in here so my brilliant idea was

28
00:01:58,320 --> 00:02:05,119
what if we took all of our editing workstations and removed the heat from

29
00:02:02,079 --> 00:02:06,880
the room via water cooling so it started

30
00:02:05,119 --> 00:02:11,200
with redoing our editing workstations which used to be just a haphazard mix of

31
00:02:09,039 --> 00:02:15,360
parts that we had left over from reviews and are now pretty much all standardized

32
00:02:13,440 --> 00:02:19,840
so they've got n600 cases from cooler master water cooling by swift tech and

33
00:02:17,680 --> 00:02:22,959
i'll explain why there's a radiator on the outside of the system in spite of

34
00:02:21,520 --> 00:02:27,599
the whole room water cooling i'll explain that later

35
00:02:24,800 --> 00:02:31,760
we've got 4960x six core processors those are extreme editions 32 gigs of

36
00:02:29,360 --> 00:02:38,000
kingston memory ASUS x99 deluxe motherboards gtx titan blacks so those

37
00:02:35,120 --> 00:02:41,680
are six gig vram cards we've also got cooler master v750 power supplies and

38
00:02:40,160 --> 00:02:46,720
all of them except exiles which actually has two of these a quadro a 10 gigabit

39
00:02:44,080 --> 00:02:51,280
nick and then a v 1200 because uh his system is kind of balls to the wall and

40
00:02:48,480 --> 00:02:56,560
then each system has its own pump as well so the way that it all works is

41
00:02:53,920 --> 00:03:00,720
that at the back we've got kind of a a tangle of of tubing going on here so

42
00:02:59,280 --> 00:03:05,680
we've got quick release fittings here so we can either

43
00:03:03,440 --> 00:03:11,200
connect to the radiator on the top which is running quite toasty right now or

44
00:03:08,319 --> 00:03:16,879
to the whole room system and this was actually all done up by luke's dad who

45
00:03:13,280 --> 00:03:19,680
did an amazing job of plumbing the

46
00:03:16,879 --> 00:03:25,920
entire room for us so you can see the terminus station is actually over here

47
00:03:23,040 --> 00:03:30,799
by nick van berkel's pc so every one of these systems has an inlet and then an

48
00:03:28,480 --> 00:03:35,200
outlet and they all join together as you go around the room we actually left

49
00:03:32,480 --> 00:03:41,280
enough space to have up to seven systems water cooled all at the same

50
00:03:38,000 --> 00:03:42,319
time all on the same loop and in the

51
00:03:41,280 --> 00:03:47,360
bathroom server room this is where the magic

52
00:03:44,799 --> 00:03:53,599
happens so here's our mechanical and then uh uv sterilizing filters here is

53
00:03:50,720 --> 00:03:59,120
our reservoir here are our dual little giant pumps and then those lead to a

54
00:03:56,640 --> 00:04:05,840
radiator fan setup using Noctua industrial ppc fans so those waterproof

55
00:04:02,400 --> 00:04:08,239
dust proof ones on the roof of the house

56
00:04:05,840 --> 00:04:13,760
so that we are actually physically removing the heat from the building in

57
00:04:11,040 --> 00:04:18,079
order to keep our systems cool we've got a cover on there we've got a power

58
00:04:15,200 --> 00:04:22,240
supply for all of the fans to run as well

59
00:04:18,880 --> 00:04:24,639
so with that recapped how does it

60
00:04:22,240 --> 00:04:28,800
perform so to evaluate our success there's a number of different metrics to

61
00:04:26,880 --> 00:04:34,479
look at we can look at the cooling performance of the individual systems

62
00:04:31,600 --> 00:04:39,840
based on how hot their cpus run during an intensive task like video rendering

63
00:04:37,280 --> 00:04:45,360
we can look at the room temperature inside versus the temperature outside to

64
00:04:42,960 --> 00:04:51,120
see if removing the heat from the room actually yielded any kind of benefit and

65
00:04:48,639 --> 00:04:56,560
we can look at the convenience and maintenance factors so let's start with

66
00:04:53,520 --> 00:05:00,240
CPU temperatures when we're running the

67
00:04:56,560 --> 00:05:02,880
cpus on their own radiators the room

68
00:05:00,240 --> 00:05:07,120
reaches a temperature of about 31 degrees so you can actually see that

69
00:05:04,560 --> 00:05:11,280
right now which is about a three degree difference between the inside and the

70
00:05:09,360 --> 00:05:15,680
outside and you should bear in mind that that's on a day that's not particularly

71
00:05:13,520 --> 00:05:20,639
sunny which can cause the room to heat up quite a bit more than the computers

72
00:05:17,600 --> 00:05:24,160
could possibly affect all the systems

73
00:05:20,639 --> 00:05:27,120
and the sort of 45 degree plus range on

74
00:05:24,160 --> 00:05:31,919
the CPU which is reasonable except for terrans which i'll talk more about later

75
00:05:30,000 --> 00:05:37,600
and edsels which has an additional graphics card but no additional radiator

76
00:05:34,960 --> 00:05:42,400
space for cooling so that one's bound to run a little bit on the hotter side so

77
00:05:40,160 --> 00:05:46,560
now what we're gonna do is we are going to take the running whole room system

78
00:05:44,639 --> 00:05:51,600
i'll show you guys how we quickly connect and disconnect them

79
00:05:49,440 --> 00:05:56,000
so while they're running probably not recommended but we've done it so many

80
00:05:53,520 --> 00:06:00,400
times anyway that it i've lost all fear of the process

81
00:05:58,800 --> 00:06:05,440
all we do is use these to hook it up

82
00:06:03,120 --> 00:06:07,840
to the whole room system now

83
00:06:07,919 --> 00:06:16,800
what you are likely to see here is a nearly instantaneous drop

84
00:06:14,400 --> 00:06:22,000
in CPU temperatures so we've gone from 47 on core 1 to 41

85
00:06:20,319 --> 00:06:27,280
and i'll make some graphs here showing you guys the difference in CPU temps

86
00:06:24,319 --> 00:06:31,440
under load from system to system to dramatically reduce temperatures across

87
00:06:29,759 --> 00:06:36,960
the board by hooking up to the whole room system why does that work well it's just a

88
00:06:35,039 --> 00:06:42,560
matter of radiator capacity we could just as easily achieve great CPU

89
00:06:39,919 --> 00:06:46,560
temperatures by hooking up much much larger radiators as you'll see in some

90
00:06:44,639 --> 00:06:51,199
very large towers this will support like quad rads in the front duals in the top

91
00:06:48,560 --> 00:06:56,000
a single in the back and the like another advantage of this approach by

92
00:06:53,520 --> 00:07:00,400
having it outside is that you don't end up with a chain reaction of the room

93
00:06:58,160 --> 00:07:04,080
temperature increasing and therefore the cooling efficiency of your radiator

94
00:07:02,000 --> 00:07:07,840
increasing because you're always tied to ambient temperatures but

95
00:07:06,400 --> 00:07:12,000
that's a great question if one of the objectives was to lower the ambient

96
00:07:09,680 --> 00:07:16,400
temperature in the room with this system how much have you achieved the answer is

97
00:07:14,240 --> 00:07:21,520
not a heck of a lot we achieved a one degree drop by hooking all of these

98
00:07:18,880 --> 00:07:26,960
systems up which i would consider within the sort of margin of error the sort of

99
00:07:24,400 --> 00:07:32,160
a vague sort of concept so being able to align this correctly helps a lot

100
00:07:29,680 --> 00:07:37,280
on our inlet so that's the cold side we're getting 29.7 degrees

101
00:07:35,199 --> 00:07:40,599
and on our outlet that's the hot side

102
00:07:39,520 --> 00:07:46,240
we are getting 30.0 degrees which i'm sure someone out

103
00:07:43,759 --> 00:07:50,479
there is calculating the specific heat of this you know mass of water or

104
00:07:49,039 --> 00:07:54,319
whatever the case may be and i'm sure that we are actually dissipating a

105
00:07:52,319 --> 00:07:59,039
significant amount of the heat outside but that is where the whole

106
00:07:56,560 --> 00:08:03,360
was it actually practical thing comes into play because by going with copper

107
00:08:01,599 --> 00:08:08,400
tubing which i think we can all agree is more aesthetically pleasing than

108
00:08:05,599 --> 00:08:12,960
insulated pvc we actually created a situation where we are dissipating a

109
00:08:10,720 --> 00:08:16,960
significant amount of the heat we're pulling out of each system

110
00:08:15,520 --> 00:08:24,319
into the room anyway anyway via the copper piping

111
00:08:21,199 --> 00:08:26,960
so i guess all that's really left now is

112
00:08:24,319 --> 00:08:32,000
do we consider the project a success the answer is no um i still think the

113
00:08:29,759 --> 00:08:35,839
concept could have worked really well but there were a few critical things

114
00:08:34,000 --> 00:08:42,719
that i really think we could have done differently number one don't use a metal

115
00:08:38,240 --> 00:08:44,959
reservoir don't use a metal reservoir

116
00:08:42,719 --> 00:08:49,760
find some kind of plastic reservoir to use because that's where the thing that

117
00:08:47,120 --> 00:08:55,600
i promised to talk about later comes in terran system has some big problems

118
00:08:52,640 --> 00:09:01,040
caused by corrosion bits stuck in his system that even cleaning out his CPU

119
00:08:58,959 --> 00:09:06,880
block which was extremely gunked up that was a picture i posted on instagram

120
00:09:02,959 --> 00:09:09,040
could not fix and um

121
00:09:06,880 --> 00:09:13,200
point number two is i would definitely recommend installing some kind of a

122
00:09:10,720 --> 00:09:17,040
bleed system at the highest point in the loop that way you are not going to have

123
00:09:14,720 --> 00:09:21,519
as much difficulty filling the system each time uh compared to

124
00:09:19,680 --> 00:09:25,519
us where we had to add a second pump in order to have enough flow rate and

125
00:09:23,279 --> 00:09:30,560
enough pressure in order to get the water in and the air out of our tubing

126
00:09:28,880 --> 00:09:35,839
system uh the other thing that i would do differently next time is um

127
00:09:33,839 --> 00:09:38,399
wow gee i guess that ties into a question that we've been asked a lot

128
00:09:37,040 --> 00:09:41,680
aren't you guys moving why did you bother with all of this and are you

129
00:09:40,080 --> 00:09:45,920
gonna do whole room water cooling at the new place well number one we weren't

130
00:09:43,600 --> 00:09:49,519
planning to move when we originally came up with this concept and started working

131
00:09:47,760 --> 00:09:55,519
on it so there's that uh number two no we do not

132
00:09:52,560 --> 00:09:59,040
intend to water cool our systems let alone whole room water cool our systems

133
00:09:57,680 --> 00:10:03,360
at the new office we're gonna have air conditioning which is probably the

134
00:10:01,440 --> 00:10:09,360
solution that we should have gone with in the first place if the objective was

135
00:10:05,680 --> 00:10:13,120
to lower the temperature in this room

136
00:10:09,360 --> 00:10:13,839
and have our computers run cooler

137
00:10:13,120 --> 00:10:20,880
so i think that's pretty much it thank you guys for sticking with us throughout the

138
00:10:18,720 --> 00:10:26,160
whole room water cooling project we learned a lot i think we established the

139
00:10:23,200 --> 00:10:32,880
feasibility of it the performance and the silence factor cannot be denied but

140
00:10:30,160 --> 00:10:38,160
the convenience factor of it leaves a lot to be desired and the

141
00:10:36,079 --> 00:10:43,600
the execution of it would be extraordinarily time consuming and even

142
00:10:40,959 --> 00:10:47,920
more expensive than what we did if you were to really do it properly in such a

143
00:10:46,320 --> 00:10:51,760
way that it would require little or zero maintenance over the long

144
00:10:50,720 --> 00:10:56,160
run thanks for watching guys uh if you
