1
00:00:07,919 --> 00:00:15,799
as you guys probably know I'm a huge fan of noctu a fan so I'm super excited to

2
00:00:11,880 --> 00:00:17,760
check out the NF A14 flx now as you know

3
00:00:15,799 --> 00:00:22,400
we've got a wide variety of different 120 mm cooling fans available from nocta

4
00:00:20,800 --> 00:00:26,359
including their FS series and their P series which are optimized for radiators

5
00:00:24,840 --> 00:00:31,840
and heat sinks because they're very pressure optimized with the F series The

6
00:00:28,640 --> 00:00:34,640
F12 actually having a directed Cyclone

7
00:00:31,840 --> 00:00:39,360
of air coming away from the exhaust side of it now this doesn't have that

8
00:00:36,840 --> 00:00:43,719
functionality but this is a 140 mm version of what would be very similar to

9
00:00:41,800 --> 00:00:47,640
a p12 fan but with some additional technology so if you come in here and

10
00:00:45,200 --> 00:00:53,079
have a look at the actual features that are available on it we've got a square

11
00:00:49,520 --> 00:00:56,239
140 mm frame this makes it ideal for Cas

12
00:00:53,079 --> 00:00:57,840
in r ah yes well you can see nocta puts

13
00:00:56,239 --> 00:01:01,960
right here what what it's for case and radiator cooling flow acceleration Chann

14
00:01:00,239 --> 00:01:06,040
AO frame stepped Inlet design inner surface micro structures integrated anti

15
00:01:03,600 --> 00:01:11,280
vibration pad smooth commutation drive to basically what noct was trying to say

16
00:01:08,479 --> 00:01:16,520
is their drives are engineered to the point of it being kind of obsessive so

17
00:01:14,600 --> 00:01:24,119
come in here and have a look at the uh fan itself and the accessories so unlike

18
00:01:20,799 --> 00:01:26,560
the 120 mm fans the 140 mil fans come

19
00:01:24,119 --> 00:01:31,840
with not only a low noise adapter low noise adapter right there which uh down

20
00:01:28,400 --> 00:01:34,640
volts the fan to 7 volts but also an

21
00:01:31,840 --> 00:01:39,079
ultra hold on a second okay well one of these is ultra

22
00:01:37,640 --> 00:01:45,079
low noise one of them is low noise so one of them is 7 volts and one of them is 5 volts also comes with a Molex to

23
00:01:43,000 --> 00:01:48,479
three pin adapter very nicely sleeved all of them right up to the connector so

24
00:01:47,040 --> 00:01:54,079
you're not going to see any unsightly colored wires we've also got extension

25
00:01:51,119 --> 00:01:57,920
cables this is fantastic see just a simple three pin extension cable

26
00:01:56,399 --> 00:02:02,280
mounting screws although usually you won't use those you'll use the rubber

27
00:01:59,560 --> 00:02:06,680
ice ating antivibration mounts I mean you can though because

28
00:02:04,759 --> 00:02:09,640
you've got more antivibration mounts here the only problem with using the

29
00:02:08,080 --> 00:02:13,640
metal screws is because they have to drive into hard plastic and they will

30
00:02:11,800 --> 00:02:17,800
transfer some vibration to the case that way even with these rubber isolators so

31
00:02:16,080 --> 00:02:22,599
if you use these rubber isolators up against the case with these rubber

32
00:02:19,959 --> 00:02:26,519
isolators Bridging the hard plastic with the hard metal of the case itself then

33
00:02:24,519 --> 00:02:30,200
you've got no room for vibration to be transferred from the fan to the chassis

34
00:02:28,599 --> 00:02:33,680
when it's spinning not to say that KN to a fans actually create a whole ton of

35
00:02:31,920 --> 00:02:39,440
vibration when they're spinning because they really don't the fans all come with

36
00:02:36,840 --> 00:02:43,599
short cables love this because it means that no matter where you install them I

37
00:02:41,280 --> 00:02:46,480
mean really a case is only so big usually where you install it there's

38
00:02:45,239 --> 00:02:50,560
going to be a fan header somewhere nearby if there isn't they've included

39
00:02:48,560 --> 00:02:56,040
the extension that you need to run it wherever it needs to go that makes it

40
00:02:52,000 --> 00:02:57,560
more like a normal fan wire length love

41
00:02:56,040 --> 00:03:02,720
this too check this out this is a newer feature that they've started adding to their fans see these right here I

42
00:03:01,440 --> 00:03:07,599
couldn't figure out what they were for at first I thought they were just for

43
00:03:04,640 --> 00:03:11,280
sort of mounting the uh the rubber noise isolators then what I realized is these

44
00:03:09,480 --> 00:03:15,400
are probably for cable management check this out so whenever you you know when

45
00:03:13,400 --> 00:03:18,799
you wrap a wire around the outside of a fan maybe they're not for that but

46
00:03:16,959 --> 00:03:23,040
whatever you can use them for that all you got to do is put them under these

47
00:03:20,560 --> 00:03:26,799
little rubber pieces and they will generally stay there very very cool

48
00:03:25,080 --> 00:03:29,879
stuff like you know when you take a fan and you mount it kind of like here at

49
00:03:28,720 --> 00:03:35,360
the back of your chassis and then you want to wrap it here down to here and then run it to a little W awesome for

50
00:03:33,680 --> 00:03:38,439
that so I want you to have a closer look at these rubber isolators you can remove

51
00:03:37,080 --> 00:03:42,319
them if you want you don't have to keep them on you know say in the odd case

52
00:03:41,200 --> 00:03:46,840
that it causes some kind of a compatibility issue with your case or your cooler or anything like that you

53
00:03:45,159 --> 00:03:50,760
don't have to worry about it so let's have a look at some of the technologies

54
00:03:48,400 --> 00:03:57,000
that NOA builds into the fan number one is the six-year warranty um so basically

55
00:03:53,959 --> 00:03:58,680
what they're saying is 150,000 hours or

56
00:03:57,000 --> 00:04:02,760
something like that is the meantime between failure for this thing and yeah

57
00:04:01,120 --> 00:04:05,840
there you go meantime between failure of greater than 150,000 hours so they're

58
00:04:04,840 --> 00:04:09,959
pretty much saying yeah it's not going to die but if it does we'll deal with it

59
00:04:07,920 --> 00:04:14,280
without adapters it runs at 1200 RPM with an adapter this is the wrong fan uh

60
00:04:12,280 --> 00:04:20,919
with an adapter this one also runs at 1200 RPM but low noise adapters at 1050

61
00:04:17,120 --> 00:04:24,680
ultra low noise at 900 RPM so at 900 RPM

62
00:04:20,919 --> 00:04:27,600
this thing will be darn near

63
00:04:24,680 --> 00:04:32,600
silent all right technology wise these guys right here these stepped inlets

64
00:04:29,960 --> 00:04:36,840
apparently reduced the amount of noise that is here we go stepped Inlet design

65
00:04:35,440 --> 00:04:40,720
stepped Inlet design is Advanced aerodynamic design blah blah blah with

66
00:04:38,840 --> 00:04:44,919
first with the F12 the F12 was one of their most advanced fans ever by adding

67
00:04:42,600 --> 00:04:48,600
turbulence to the influx facilitates the transition from laminer turbulent flow

68
00:04:46,759 --> 00:04:51,680
so similar to The dimple structure of the golf ball leads to better flow

69
00:04:50,360 --> 00:04:57,400
attachment to the frame which allows the impeller to suck in more air and helps improve overall air efficiency they also

70
00:04:55,720 --> 00:05:01,759
use a very Advanced bearing that is completely sealed so you won't get any

71
00:04:59,160 --> 00:05:06,520
micro inside they use flow accelerator channels on the blades themselves which

72
00:05:04,320 --> 00:05:11,000
is there's lots of complicated stuff here generally

73
00:05:08,039 --> 00:05:14,000
speaking I am not an aerodynamic engineer I think you guys know this

74
00:05:12,639 --> 00:05:19,919
you've watched enough of my videos to know that that's not the case what I do know is that these fans are extremely

75
00:05:17,720 --> 00:05:23,000
well regarded even by those who have very

76
00:05:20,720 --> 00:05:26,560
advanced Advanced Equipment for testing fans I know this because I spent some

77
00:05:24,800 --> 00:05:29,960
time using their equipment testing Noctua fans and they were just like yeah

78
00:05:28,160 --> 00:05:33,240
they're they're really good fans they're they're just really good um I do know

79
00:05:31,759 --> 00:05:37,000
that they last over the long term I've been using Noctua fans for a very long

80
00:05:35,360 --> 00:05:41,759
time on some of my quiet optimized systems and what I also know is that

81
00:05:39,039 --> 00:05:46,039
they're darn silent now guys there's more to it than just the RPM the CFM and

82
00:05:44,000 --> 00:05:50,600
the static pressure and the deciel ratings there's more to it than that

83
00:05:47,840 --> 00:05:54,880
there's how gracefully does it undervolt so some fans yes you can undervolt them

84
00:05:53,039 --> 00:06:00,319
but they start to develop a grind or a tick that doesn't necessarily get picked

85
00:05:57,280 --> 00:06:02,520
up by a decimeter so so yeah you know

86
00:06:00,319 --> 00:06:06,840
it's there an audible noise but it's more about how annoying is that noise

87
00:06:04,319 --> 00:06:12,880
nocta fans don't make annoying noises they you know sure maybe they look kind

88
00:06:08,919 --> 00:06:12,880
of distinctive

89
00:06:12,960 --> 00:06:17,840
but that's their branding you can always

90
00:06:16,000 --> 00:06:21,599
tell a no to a fan when you see it so this guy right here perfect for

91
00:06:19,319 --> 00:06:27,160
radiators perfect for heat sinks oh yeah why is it perfect for radiators good

92
00:06:23,599 --> 00:06:29,720
question cuz nocta has 140 and 150 mm

93
00:06:27,160 --> 00:06:33,599
fans that use a round frame which is not for radiators because you'll lose the

94
00:06:31,319 --> 00:06:38,199
seal around the edges and in the corners like that which causes it to be less

95
00:06:35,360 --> 00:06:41,080
efficient this way the fan gets to go right up against this is a 120 mil rad

96
00:06:39,800 --> 00:06:44,919
I'm just using it for illustration purposes gets to go right up against it

97
00:06:43,280 --> 00:06:48,919
and causes a seal so that pressure optimized design actually gets to push

98
00:06:46,720 --> 00:06:52,720
air through the fins of the rad or the heat sink rather than worrying about it

99
00:06:50,840 --> 00:06:56,560
spilling around the edges you can see an example of where this wouldn't matter in

100
00:06:54,520 --> 00:07:01,680
this computer right here come on in closer because here we're going to have

101
00:06:59,199 --> 00:07:05,280
leaks around the edges no matter what so as long as we have reasonably good

102
00:07:03,360 --> 00:07:08,960
directed air flow through the fins we're going to be fine so you could use

103
00:07:06,599 --> 00:07:14,400
something like their A5 instead of their A14 it wouldn't be necessary to have

104
00:07:10,879 --> 00:07:15,720
that square shaped uh fan Arrangement so

105
00:07:14,400 --> 00:07:20,240
let's just make sure we don't miss any of the other Technologies they include so we got the flow acceleration chance

106
00:07:18,560 --> 00:07:24,599
with the advanced acoustic optimization frame stepped in inner surface micr

107
00:07:22,160 --> 00:07:28,280
structures so these flow separation from the suction sides which reduces reduced

108
00:07:26,680 --> 00:07:31,919
blade passing noise and improved air flow and pressure efficiency the anti

109
00:07:30,319 --> 00:07:35,199
vibration pads we covered running smoothness by

110
00:07:33,960 --> 00:07:39,199
eliminating torque variations and switching noises this is actually

111
00:07:37,479 --> 00:07:45,240
something that's uh that's really good to know about so guys the circuitry and

112
00:07:43,120 --> 00:07:49,919
the design of the of the fan motor as well as the pwm or actually these aren't

113
00:07:47,280 --> 00:07:54,159
pwm fans but they do have pwm fans these guys are makes a huge difference in

114
00:07:52,039 --> 00:07:58,919
using thirdparty fan controllers on fans so the more optimized it is and the more

115
00:07:57,520 --> 00:08:02,479
well the higher quality the components that are used the less likely you are to

116
00:08:00,599 --> 00:08:07,560
develop any sort of weird vibrations ticking or whining noises okay three

117
00:08:05,599 --> 00:08:11,520
speeds ultra low power consumption and six-year warranty metal bearing shell so

118
00:08:10,240 --> 00:08:15,120
Poss highest possible degree of manufacturing Precision minimum uh

119
00:08:13,960 --> 00:08:20,879
tolerance and excellent long St stability CNC mil bearing shell made entirely from breast okay so there you

120
00:08:18,960 --> 00:08:23,879
go quality fans yeah they're expensive but you get what you pay for thanks guys

121
00:08:22,560 --> 00:08:27,879
