1
00:00:00,040 --> 00:00:05,600
we're here at kutex 2024 to look at what

2
00:00:03,080 --> 00:00:11,960
might be one of the biggest Innovations in water cooling in years and years this

3
00:00:09,040 --> 00:00:18,840
right here is the cold plate of an aiio but all of it has been metal 3D printed

4
00:00:15,120 --> 00:00:20,920
onto here and it is so flipping cool now

5
00:00:18,840 --> 00:00:24,720
how an AIO works is pretty simple you've got your radiator right here that yeets

6
00:00:22,800 --> 00:00:29,400
the heat out got a pump that pumps the water around but the bit that we are

7
00:00:26,840 --> 00:00:34,280
interested in is the cold plate right here and that can have a huge impact on

8
00:00:32,200 --> 00:00:39,399
your performance because how good this is at getting the heat out of your CPU

9
00:00:36,960 --> 00:00:46,600
can be completely transformative to how good your AIO can perform and what we

10
00:00:42,800 --> 00:00:48,960
have here is from fabric 8 Labs if you

11
00:00:46,600 --> 00:00:55,000
look instead of your typical fins that will just be like skyed on we have

12
00:00:52,199 --> 00:00:59,079
complete freedom of what geometry we want one of the most important things

13
00:00:56,920 --> 00:01:03,519
for getting your CPU cool is having loads of surface area of the copper

14
00:01:01,559 --> 00:01:07,520
above it now in the past that was done through skying basically you take a

15
00:01:05,479 --> 00:01:13,240
really sharp blade and a whole bunch of weight and you just push off a tiny

16
00:01:10,400 --> 00:01:17,640
little sliver a whole bunch of times but the problem is that with this process

17
00:01:15,159 --> 00:01:22,479
you have no control over the geometry besides just how thick the copper is and

18
00:01:20,079 --> 00:01:28,560
how big the space is between each fin now though we can do stuff like this or

19
00:01:25,880 --> 00:01:33,799
like this or like this and we have complete Freedom over over the flow path

20
00:01:31,439 --> 00:01:38,079
completely and the most insane thing they used AI in a way that's not just

21
00:01:35,479 --> 00:01:41,759
completely stupid this is a cold plate that's optimized for Threadripper so

22
00:01:39,880 --> 00:01:46,759
those are massive and also because Threadripper has multiple dieses you

23
00:01:43,920 --> 00:01:50,880
can have some really hot spots on there and it can be really difficult to get

24
00:01:48,360 --> 00:01:56,159
that heat away evenly but what they have done here is by having that heat map put

25
00:01:53,759 --> 00:02:01,119
into an AI model they were able to generate a whole bunch of different ways

26
00:01:58,759 --> 00:02:06,560
to do the flow path and they eventually came up with this right here as the

27
00:02:03,200 --> 00:02:08,679
absolute best option and it is crazy

28
00:02:06,560 --> 00:02:13,239
like if you look where the die is here they have some little blockers so most

29
00:02:11,720 --> 00:02:18,599
of the flow will be going over your really hot bits and then you can have

30
00:02:15,239 --> 00:02:20,560
way less flow on the outsides here it's

31
00:02:18,599 --> 00:02:25,000
really freaking cool oh jeez we nearly forgot to segue to our sponsor thanks to

special deal with a risk-free 30-day money back guarantee what we've got here

40
00:02:58,440 --> 00:03:05,640
is a really cool example of how you can change the pitch of the

41
00:03:02,800 --> 00:03:10,840
fins on your heat sink so that you can optimize for the size of your pump so if

42
00:03:08,360 --> 00:03:14,440
you look on this side they are really really tight and that is going to mean

43
00:03:12,519 --> 00:03:18,879
that you're going to have a whole lot of pressure and super high velocity of your

44
00:03:17,040 --> 00:03:22,440
fluid but if you do that across your entire heat sink like you would if you

45
00:03:20,519 --> 00:03:27,840
had a whole bunch of really tight Sky fins you're going to need a massive pump

46
00:03:25,799 --> 00:03:31,720
to push water through all of that so instead here you can see that on the

47
00:03:29,360 --> 00:03:36,400
right it's super dense but then it gets progressively less dense as we go across

48
00:03:34,319 --> 00:03:40,519
so that you can have a whole bunch of high pressure high velocity fluid on the

49
00:03:38,560 --> 00:03:44,439
right but then maybe over here if you don't care as much about the thermal

50
00:03:42,239 --> 00:03:48,920
performance it's a bit easier on your pump system I've been following fabric 8

51
00:03:46,920 --> 00:03:53,959
Labs for a little bit and their 3D printed water cooling stuff but what I

52
00:03:51,239 --> 00:03:58,200
was not expecting was anytime in like the next 10 years to see it as a

53
00:03:56,360 --> 00:04:03,040
commercial product but that's what we have right here they have teamed up with

54
00:04:00,000 --> 00:04:05,120
acch to make a completely 3D printed

55
00:04:03,040 --> 00:04:11,200
coal plate and they say that for every 100 Watts that your CPU outputs this

56
00:04:07,480 --> 00:04:13,720
rate here can drop 2° C so say that you

57
00:04:11,200 --> 00:04:19,959
have a 300 W CPU that means that you have 6° more cooling with this guy that

58
00:04:17,280 --> 00:04:24,759
is crazy I've been talking about 3D printing but uh how the heck 3D printing

59
00:04:23,360 --> 00:04:29,720
well it's a thing that's called electrochemical additive manufacturing

60
00:04:27,040 --> 00:04:34,840
or ecam for sure it's kind of like putting together Electro plating and 3D

61
00:04:32,479 --> 00:04:39,520
printing into one thing and also some display technology it's sort of like

62
00:04:36,400 --> 00:04:42,160
OLED I'll explain it the process is

63
00:04:39,520 --> 00:04:46,680
similar to an SLA printer so we have our build plate on the top and our print

64
00:04:44,280 --> 00:04:52,520
head down on the bottom which is sort of like an OLED panel but instead of pixels

65
00:04:49,960 --> 00:04:57,520
that create photons to display an image it has little electrodes that create a

66
00:04:54,680 --> 00:05:03,120
current to deposit copper onto our build plate these pixels have incredible

67
00:04:59,840 --> 00:05:06,000
density 33 microns and you can have

68
00:05:03,120 --> 00:05:12,720
about two of them to create a feature for a feature size of just 60 microns or

69
00:05:09,600 --> 00:05:14,880
70 maybe that's really freaking small

70
00:05:12,720 --> 00:05:19,240
smaller than a human hair how you turn that current into copper is by Just

71
00:05:16,880 --> 00:05:25,120
Simply Having copper that is dissolved into water and this is very cheap and

72
00:05:22,319 --> 00:05:29,840
very available it is super common used in electr plating so it's actually not a

73
00:05:27,520 --> 00:05:33,280
very expensive process and if if you know anything about displays they are

74
00:05:31,600 --> 00:05:37,000
pretty much the only thing that has just kept on getting cheaper and cheaper and

75
00:05:34,960 --> 00:05:42,120
cheaper and being able to use that technology for your 3D printer means

76
00:05:39,560 --> 00:05:47,319
that we're not having to do any super crazy uh laser burning copper or stuff

77
00:05:45,400 --> 00:05:51,280
like that that's incredibly expensive instead it's actually quite scalable

78
00:05:49,319 --> 00:05:55,319
which is how we have a real product that's going to exist sometime in the

79
00:05:53,319 --> 00:05:59,880
near future now the process isn't particularly fast they're getting about

80
00:05:57,240 --> 00:06:04,400
1 mm per hour but you are able to have four of these on a build Plate at a time

81
00:06:02,120 --> 00:06:09,720
and the machines themselves are not particularly expensive so even though

82
00:06:07,000 --> 00:06:16,080
you need a lot of them it doesn't get too out of hand too fast now acch won't

83
00:06:13,800 --> 00:06:21,960
tell us exactly when they're expecting for this to hit the market but they said

84
00:06:18,360 --> 00:06:25,520
somewhere around Q3 Q4 this year and the

85
00:06:21,960 --> 00:06:28,080
pricing again TBD but they said it'll be

86
00:06:25,520 --> 00:06:32,240
a premium and given that the ryogen that it's going into is already pretty

87
00:06:29,960 --> 00:06:37,160
premium priced I don't think it'll be cheap but that said the 3D printing

88
00:06:34,479 --> 00:06:42,560
technology has lots more uses than coal plates like this one really cool example

89
00:06:40,240 --> 00:06:47,160
that they have here are some radar sensors for cars so those are looking

90
00:06:45,039 --> 00:06:50,800
out and seeing if there's you know a car in front of you for your adaptive cruise

91
00:06:48,960 --> 00:06:57,199
and stuff like that but the problem is that a traditional antenna just kind of

92
00:06:53,360 --> 00:06:59,120
yeets out electric waves that way this

93
00:06:57,199 --> 00:07:04,400
right here instead by using that metal 3D printing is able to very precisely

94
00:07:02,039 --> 00:07:09,840
control it so that you can have a really wide beam this way but not a very wide

95
00:07:07,400 --> 00:07:13,599
beam this way cuz you don't care about what's happening on the ground or the

96
00:07:11,680 --> 00:07:19,039
sky you just want to see the cyclist that's right there somewhere here you

97
00:07:16,240 --> 00:07:22,759
can see the inner geometry of how they able to create that really cool beam

98
00:07:20,960 --> 00:07:26,120
pattern and one of the best parts is that the whole process is done at room

99
00:07:24,479 --> 00:07:31,000
temperature so you don't have to be doing any crazy stuff like heating up

100
00:07:28,800 --> 00:07:35,639
your metal to super high temperatures just like you don't have to heat up to

101
00:07:33,280 --> 00:07:38,479
hit like And subscribe huge thanks for watching hit like and subscribed and

102
00:07:37,120 --> 00:07:43,879
just have a great old day we have a bunch more computex videos coming to you

103
00:07:40,280 --> 00:07:43,879
and I'll see you soon
