00:00:00,320 --> 00:00:10,240
frankly i'm not even 100 sure where to start with this one meet

2
00:00:04,960 --> 00:00:11,840
a data's spectrex d80 ddr4 memory as

3
00:00:10,240 --> 00:00:20,720
they're calling it the world's first RGB ddr4 memory with

4
00:00:16,720 --> 00:00:23,439
hybrid liquid air cooling system

5
00:00:20,720 --> 00:00:28,800
using a combination of a liquid heatsink and an aluminum heatsink to deliver

6
00:00:25,920 --> 00:00:35,760
effective thermal cooling water cooled memory

7
00:00:32,399 --> 00:00:37,200
welcome my friends to [ __ ] manufacturers

8
00:00:35,760 --> 00:00:40,079
say this

9
00:00:38,800 --> 00:00:44,160
this is water-cooled memory

10
00:00:42,239 --> 00:00:48,399
throughout this video Linus will refer to the liquid as water this is

11
00:00:45,920 --> 00:00:52,559
inaccurate the liquid is in fact 3m novak however Linus is having some

12
00:00:50,800 --> 00:00:58,440
well-deserved time off making a vocal correction impossible so here i am rock

13
00:00:55,280 --> 00:01:01,490
you like a hurricane here i

00:01:20,720 --> 00:01:26,400
description well we're off to a good start the shutdown button doesn't work

19
00:01:24,720 --> 00:01:29,759
brilliant who needs to shut down their computer anyway

20
00:01:29,759 --> 00:01:32,880
what am i supposed to do

21
00:01:32,960 --> 00:01:38,159
now i could just chart all over this stuff based on

22
00:01:36,720 --> 00:01:42,880
pure principles of cooling theory because i

23
00:01:40,720 --> 00:01:48,960
actually don't need to plug them in in order to know that the water cooling on

24
00:01:45,600 --> 00:01:51,280
them is really not doing anything but i

25
00:01:48,960 --> 00:01:56,799
at least try to take manufacturers claims somewhat seriously i want to give

26
00:01:53,439 --> 00:01:59,439
them every opportunity to prove me wrong

27
00:01:56,799 --> 00:02:02,960
here so what i'm going to do is devise an experiment one thing's for sure they

28
00:02:01,759 --> 00:02:11,039
look pretty cool other than that they have a red heat spreader on an RGB RAM module on a more

29
00:02:07,280 --> 00:02:13,840
positive note this is hours of fun

30
00:02:11,039 --> 00:02:19,280
look there's a little bubble oh this is interesting

31
00:02:15,599 --> 00:02:21,280
it makes no meaningful thermal contact

32
00:02:19,280 --> 00:02:26,959
outside of it looks like this part of the spreader might go under there

33
00:02:24,000 --> 00:02:31,040
with the actual memory chips let's start i guess with the standard stuff then or

34
00:02:29,440 --> 00:02:36,800
no let's make sure this stuff even boots up first show me the post yes

35
00:02:34,959 --> 00:02:39,360
all right now that we're booted up let's go ahead and

36
00:02:38,160 --> 00:02:45,920
press start on a stress system memory test hopefully

37
00:02:43,200 --> 00:02:51,200
our fleer camera will tell us some interesting things about what's going on

38
00:02:48,480 --> 00:02:56,319
here we can see the heat is clearly concentrated directly over the actual

39
00:02:54,000 --> 00:03:02,080
dram modules the second thing that we can see is that my suspicion

40
00:02:59,200 --> 00:03:06,319
that there was some kind of contact between

41
00:03:03,599 --> 00:03:10,720
this medallion here and the water cooling at the top was

42
00:03:08,800 --> 00:03:14,480
probably not correct it looks like the only places

43
00:03:12,319 --> 00:03:19,120
where heat is being transferred up into the top chamber

44
00:03:16,239 --> 00:03:22,800
are kind of over here and i'm not sure why

45
00:03:20,640 --> 00:03:27,120
and then kind of over here so those are almost the same temperature

46
00:03:24,959 --> 00:03:29,680
as the spot directly over the chips so you can see if we look directly over top

47
00:03:28,720 --> 00:03:32,799
of it the water cooling portion is still quite

48
00:03:32,000 --> 00:03:38,959
cool okay so after a few minutes of testing our thermals have stabilized anywhere

49
00:03:36,400 --> 00:03:42,720
from around 47 to 50 degrees depending on where exactly we're looking on the

50
00:03:41,040 --> 00:03:47,440
spreader here but that's not that interesting we were expecting that what

51
00:03:44,640 --> 00:03:52,159
we did figure out that is interesting is why we're seeing those little

52
00:03:49,920 --> 00:03:56,080
centers of activity of thermal movement up here

53
00:03:53,440 --> 00:04:01,280
that actually came from perusing a data it's very optimistic by the way diagram

54
00:03:59,120 --> 00:04:03,920
of how these modules work so

55
00:04:02,159 --> 00:04:08,560
heat gets generated by these uh dram packages right here

56
00:04:07,120 --> 00:04:11,599
with you so far then it gets

57
00:04:10,319 --> 00:04:15,599
like i don't know it goes through these holes i'm not sure what they're talking about but there's there's a heat

58
00:04:14,000 --> 00:04:21,040
spreader here that then somehow theoretically heat up

59
00:04:18,320 --> 00:04:25,759
or something anyway the point is once the assembly is put together there's an

60
00:04:23,040 --> 00:04:30,240
actual heat spreader portion here and here that's causing those hot zones on

61
00:04:28,080 --> 00:04:35,919
these sides the reason this one doesn't work is because on a standard ddr4

62
00:04:32,960 --> 00:04:40,080
memory module there is no chip in the middle so there's

63
00:04:37,759 --> 00:04:43,520
no heat for this to carry away this is more efficient than this chunk of metal

64
00:04:42,160 --> 00:04:47,680
so we're going to go ahead and throw my regular test bench memory back in here

65
00:04:45,759 --> 00:04:51,440
and we'll compare against that so we still need a few more minutes with

66
00:04:49,520 --> 00:04:57,280
our other memory modules here but it looks like we're going to end up

67
00:04:52,880 --> 00:04:58,639
somewhere in the 40 to 40 something mid

68
00:04:57,280 --> 00:05:02,400
range so it took a little longer thanks to the

69
00:05:00,560 --> 00:05:08,320
additional thermal mass of these trident z modules but we are back up to

70
00:05:05,120 --> 00:05:09,440
anywhere between about 50 degrees and 47

71
00:05:08,320 --> 00:05:14,880
degrees just like last time so

72
00:05:12,560 --> 00:05:20,240
the rules of the game have not in fact changed RAM doesn't really need cooling

73
00:05:18,160 --> 00:05:25,440
unless you're you know extreme overclocking it to break records and

74
00:05:23,039 --> 00:05:30,880
heat spreaders don't really do a whole lot for it regardless of the design of

75
00:05:28,080 --> 00:05:35,360
them so what conclusion can we draw about this thing then i guess the best

76
00:05:33,280 --> 00:05:38,479
way i could describe it would be this

77
00:05:36,639 --> 00:05:41,600
the water on the top of these RAM modules

78
00:05:39,680 --> 00:05:45,280
it's not hurting anything it's like homeopathic pills where they just

79
00:05:44,000 --> 00:05:49,520
contain basically nothing

80
00:05:47,039 --> 00:05:56,720
but it's not helping anything and as much as we love our friends over

81
00:05:52,880 --> 00:05:58,720
at adata to say that it is water cooled

82
00:05:56,720 --> 00:06:03,759
is about like it would be for me to say that this CPU with a bubble of water on

83
00:06:00,960 --> 00:06:08,800
the middle of it is water cooled water does not inherently cool anything

84
00:06:07,120 --> 00:06:13,199
you have to have surface area that's why water cooling

85
00:06:10,960 --> 00:06:18,720
still needs radiators that's why heat sinks need fins and not just heat pipes

86
00:06:17,199 --> 00:06:24,000
well that whole thing was enlightening isn't learning fun

87
00:06:21,000 --> 00:06:25,520
brilliant.org sure thinks so brilliant

88
00:06:24,000 --> 00:06:30,560
is a problem-solving website that teaches you to think like a computer

89
00:06:27,759 --> 00:06:35,280
scientist by diving in and doing things for yourself rather than just trying to

90
00:06:32,880 --> 00:06:39,280
passively learn from lectures and videos they believe that a great education

91
00:06:37,360 --> 00:06:44,160
shows you how to solve new and unfamiliar problems by using critical

92
00:06:41,840 --> 00:06:49,039
reasoning skills with that said you do need a toolkit and a framework in order

93
00:06:46,639 --> 00:06:53,919
to work through things fortunately they also provide you with that so they'll

94
00:06:51,600 --> 00:06:58,080
take learning concepts break them up into bite-sized pieces present clear

95
00:06:56,319 --> 00:07:02,240
thinking in each part and then build back up to an interesting conclusion

96
00:07:00,240 --> 00:07:08,080
head over to brilliant.org forward slash Linus tech tips and try it you get 20

97
00:07:05,280 --> 00:07:13,039
off at the link in the video description so thanks for watching guys if you

98
00:07:09,440 --> 00:07:15,039
disliked this video then um

99
00:07:13,039 --> 00:07:19,280
you know i'm sorry to hear that it's a sad time for all of us but if you

100
00:07:17,199 --> 00:07:22,639
liked it hit like get subscribed and maybe consider checking out where to buy

101
00:07:20,639 --> 00:07:26,080
the stuff we featured at the link in the video description

102
00:07:24,240 --> 00:07:29,680
i mean to be very clear you guys it's not like it's bad memory you could still

103
00:07:27,840 --> 00:07:34,720
buy it if you're into just like RGB memory with a cool bar on the top

104
00:07:32,880 --> 00:07:38,319
also linked in the description is our merch store which has cool shirts like

105
