00:00:00,080 --> 00:00:05,680
Linus Tech tips coverage of computex 2016 is brought to you by the Corsair

2
00:00:03,679 --> 00:00:09,280
lap dog the portable gaming control center that lets you use a full-size

3
00:00:07,120 --> 00:00:14,559
Mouse and mechanical gaming keyboard on your couch as well as MSI so here we are

4
00:00:13,240 --> 00:00:19,800
in the noct TOA Booth where they are showing off a product that has been

5
00:00:16,560 --> 00:00:23,320
three years in the making this my

6
00:00:19,800 --> 00:00:27,519
friends is the unnamed unlabeled

7
00:00:23,320 --> 00:00:29,519
successor to the nf12 fan and we don't

8
00:00:27,519 --> 00:00:33,800
know much about it other than that it is a balanced blade design so they're

9
00:00:32,040 --> 00:00:40,000
saying it's going to be perfect for radiators and heat sinks and that it has

10
00:00:36,680 --> 00:00:41,680
been an absolute to manufacture

11
00:00:40,000 --> 00:00:47,520
and the reason for that is that in order to achieve the well a few things so the

12
00:00:44,640 --> 00:00:52,079
air flow noise and reliability that they're going for they needed 0.5 millim

13
00:00:50,520 --> 00:00:56,879
of clearance between the blades and the outside of the frame the problem with

14
00:00:54,160 --> 00:01:01,600
that and uh our my friends that knock to us said that this was news to them too

15
00:00:58,879 --> 00:01:05,479
is that fans as they spin over time actually flatten out so in their

16
00:01:03,920 --> 00:01:09,720
reliability testing the blades were hitting the damn frame so it has been a

17
00:01:07,759 --> 00:01:15,960
complete nightmare to get the tolerances close enough to have a true successor to

18
00:01:12,200 --> 00:01:17,799
the nff 12 but they say they're close so

19
00:01:15,960 --> 00:01:22,040
hopefully it's happening pretty soon what they also have here is a way of

20
00:01:19,920 --> 00:01:26,320
improving the look of your existing Noctua heat sink so this doesn't look

21
00:01:24,759 --> 00:01:30,400
like it normally would no these are chromax covers so they're kind of these

22
00:01:28,600 --> 00:01:36,159
stealth metal covers that you can put over top of your existing nhd15 or your

23
00:01:34,000 --> 00:01:39,119
existing nhu 12s and they've got a couple of different variants they're

24
00:01:37,320 --> 00:01:42,840
showing off they've got a plain one and one that it looks like will be a bit

25
00:01:40,479 --> 00:01:47,399
more expensive with these little colored arrows that show through and that will

26
00:01:44,799 --> 00:01:53,360
ship with all of the chromax colors in the box so you can swap them out as you

27
00:01:50,200 --> 00:01:56,200
wish well hold on a second lonus I don't

28
00:01:53,360 --> 00:01:59,159
want to shroud for my heat sink Noctua hasn't released a heat sink like a

29
00:01:57,680 --> 00:02:04,360
performance heat sink in a million years what do they sit been on ass all day and

30
00:02:01,719 --> 00:02:10,160
the answer as far as I can tell is yes yes they do no I'm just kidding while

31
00:02:06,439 --> 00:02:13,879
they didn't bring any actual upcoming

32
00:02:10,160 --> 00:02:16,879
product they did bring a lot of excuses

33
00:02:13,879 --> 00:02:18,519
so these are five prototypes of

34
00:02:16,879 --> 00:02:23,360
different fin designs some that we've seen from noct toz competitors of

35
00:02:21,120 --> 00:02:27,680
Elsewhere in the market that basically demonstrate that yes we are looking into

36
00:02:25,560 --> 00:02:32,959
it but there's a variety of reasons to do with boundary layers and free

37
00:02:29,879 --> 00:02:34,120
streaming air and the speed of the air

38
00:02:32,959 --> 00:02:38,640
right next to the fin being significantly slower than further away from the fin which hurts thermal

39
00:02:36,720 --> 00:02:42,959
transfer and blah blah blah we we're trying all these things but the truth is

40
00:02:40,720 --> 00:02:47,519
compared to a flat fin they just don't work that well so in theory copper

41
00:02:45,560 --> 00:02:51,440
aluminum composite fins would help to spread out the heat more and would allow

42
00:02:49,599 --> 00:02:56,760
you to solder the fins directly to the heat pipes saving that nickel layer that

43
00:02:54,360 --> 00:02:59,760
would be a well a thermal barrier in practice it's very much more expensive

44
00:02:58,440 --> 00:03:04,000
and makes pretty much no difference we're talking 0. one of a degree they've

45
00:03:01,560 --> 00:03:09,879
also got an offset split fin design that breaks up that boundary layer halfway

46
00:03:07,360 --> 00:03:15,840
through each of the heat sink layers again the actual backflow from this

47
00:03:12,840 --> 00:03:16,879
design as well as this scoop so kind of

48
00:03:15,840 --> 00:03:21,400
like what you would put on the hood of your car this flow duct scoop design

49
00:03:19,519 --> 00:03:24,480
creates a situation where you actually have to throw so much more RPM at the

50
00:03:23,159 --> 00:03:29,239
problem that yes you're getting more performance but you're also ending up with a noisier product which as you guys

51
00:03:27,599 --> 00:03:33,400
are probably aware Noctua is not really that d for this guy right here they

52
00:03:31,840 --> 00:03:37,560
actually had a lot of Hope for this is oblique Groove patterns and has to do

53
00:03:35,560 --> 00:03:40,959
with kind of when the air gets sucked into a Groove It exits at a higher

54
00:03:39,519 --> 00:03:45,760
velocity and they figured maybe that would help but nothing conclusive so far

55
00:03:43,640 --> 00:03:50,159
and finally little you know golf ball type indentations and I think you've

56
00:03:48,280 --> 00:03:53,920
pretty much got the story so far so there you have it they have a better fan

57
00:03:51,840 --> 00:03:58,280
that they're finally bringing to us and that may actually if they can figure out

58
00:03:55,840 --> 00:04:01,560
how to make this one signal the solution to the problem with that active noise

59
00:03:59,959 --> 00:04:07,319
cancellation one I showed you guys two years ago and a bunch of excuses so

60
00:04:05,840 --> 00:04:11,560
thanks again to Corsair for sponsoring our trip to computex 2016 make sure you

61
00:04:09,720 --> 00:04:15,920
check out the lap dog at the link in the video description and thanks to MSI as

62
00:04:13,879 --> 00:04:20,639
well who's showing off their agis X desktop here at the show as well as

63
00:04:18,199 --> 00:04:24,160
their GTX 1080 gaming x8g got that Linked In the video

64
00:04:22,560 --> 00:04:27,320
description as well don't miss any of our computex coverage by making sure

65
00:04:25,560 --> 00:04:33,919
you're subscribed to lus Tech tips so hopefully you know where that button is

66
00:04:28,759 --> 00:04:33,919
and I will see you guys again next time
