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

00:00:11.880 --> 00:00:17.760
check out the NF A14 flx now as you know

00:00:15.799 --> 00:00:22.400
we've got a wide variety of different 120 mm cooling fans available from nocta

00:00:20.800 --> 00:00:26.359
including their FS series and their P series which are optimized for radiators

00:00:24.840 --> 00:00:31.840
and heat sinks because they're very pressure optimized with the F series The

00:00:28.640 --> 00:00:34.640
F12 actually having a directed Cyclone

00:00:31.840 --> 00:00:39.360
of air coming away from the exhaust side of it now this doesn't have that

00:00:36.840 --> 00:00:43.719
functionality but this is a 140 mm version of what would be very similar to

00:00:41.800 --> 00:00:47.640
a p12 fan but with some additional technology so if you come in here and

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

00:00:49.520 --> 00:00:56.239
140 mm frame this makes it ideal for Cas

00:00:53.079 --> 00:00:57.840
in r ah yes well you can see nocta puts

00:00:56.239 --> 00:01:01.960
right here what what it's for case and radiator cooling flow acceleration Chann

00:01:00.239 --> 00:01:06.040
AO frame stepped Inlet design inner surface micro structures integrated anti

00:01:03.600 --> 00:01:11.280
vibration pad smooth commutation drive to basically what noct was trying to say

00:01:08.479 --> 00:01:16.520
is their drives are engineered to the point of it being kind of obsessive so

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

00:01:20.799 --> 00:01:26.560
the 120 mm fans the 140 mil fans come

00:01:24.119 --> 00:01:31.840
with not only a low noise adapter low noise adapter right there which uh down

00:01:28.400 --> 00:01:34.640
volts the fan to 7 volts but also an

00:01:31.840 --> 00:01:39.079
ultra hold on a second okay well one of these is ultra

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

00:01:43.000 --> 00:01:48.479
three pin adapter very nicely sleeved all of them right up to the connector so

00:01:47.040 --> 00:01:54.079
you're not going to see any unsightly colored wires we've also got extension

00:01:51.119 --> 00:01:57.920
cables this is fantastic see just a simple three pin extension cable

00:01:56.399 --> 00:02:02.280
mounting screws although usually you won't use those you'll use the rubber

00:01:59.560 --> 00:02:06.680
ice ating antivibration mounts I mean you can though because

00:02:04.759 --> 00:02:09.640
you've got more antivibration mounts here the only problem with using the

00:02:08.080 --> 00:02:13.640
metal screws is because they have to drive into hard plastic and they will

00:02:11.800 --> 00:02:17.800
transfer some vibration to the case that way even with these rubber isolators so

00:02:16.080 --> 00:02:22.599
if you use these rubber isolators up against the case with these rubber

00:02:19.959 --> 00:02:26.519
isolators Bridging the hard plastic with the hard metal of the case itself then

00:02:24.519 --> 00:02:30.200
you've got no room for vibration to be transferred from the fan to the chassis

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

00:02:31.920 --> 00:02:39.440
vibration when they're spinning because they really don't the fans all come with

00:02:36.840 --> 00:02:43.599
short cables love this because it means that no matter where you install them I

00:02:41.280 --> 00:02:46.480
mean really a case is only so big usually where you install it there's

00:02:45.239 --> 00:02:50.560
going to be a fan header somewhere nearby if there isn't they've included

00:02:48.560 --> 00:02:56.040
the extension that you need to run it wherever it needs to go that makes it

00:02:52.000 --> 00:02:57.560
more like a normal fan wire length love

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

00:03:01.440 --> 00:03:07.599
couldn't figure out what they were for at first I thought they were just for

00:03:04.640 --> 00:03:11.280
sort of mounting the uh the rubber noise isolators then what I realized is these

00:03:09.480 --> 00:03:15.400
are probably for cable management check this out so whenever you you know when

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

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

00:03:20.560 --> 00:03:26.799
little rubber pieces and they will generally stay there very very cool

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

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

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

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

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

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

00:03:48.400 --> 00:03:57.000
that NOA builds into the fan number one is the six-year warranty um so basically

00:03:53.959 --> 00:03:58.680
what they're saying is 150,000 hours or

00:03:57.000 --> 00:04:02.760
something like that is the meantime between failure for this thing and yeah

00:04:01.120 --> 00:04:05.840
there you go meantime between failure of greater than 150,000 hours so they're

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

00:04:07.920 --> 00:04:14.280
without adapters it runs at 1200 RPM with an adapter this is the wrong fan uh

00:04:12.280 --> 00:04:20.919
with an adapter this one also runs at 1200 RPM but low noise adapters at 1050

00:04:17.120 --> 00:04:24.680
ultra low noise at 900 RPM so at 900 RPM

00:04:20.919 --> 00:04:27.600
this thing will be darn near

00:04:24.680 --> 00:04:32.600
silent all right technology wise these guys right here these stepped inlets

00:04:29.960 --> 00:04:36.840
apparently reduced the amount of noise that is here we go stepped Inlet design

00:04:35.440 --> 00:04:40.720
stepped Inlet design is Advanced aerodynamic design blah blah blah with

00:04:38.840 --> 00:04:44.919
first with the F12 the F12 was one of their most advanced fans ever by adding

00:04:42.600 --> 00:04:48.600
turbulence to the influx facilitates the transition from laminer turbulent flow

00:04:46.759 --> 00:04:51.680
so similar to The dimple structure of the golf ball leads to better flow

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

00:04:55.720 --> 00:05:01.759
use a very Advanced bearing that is completely sealed so you won't get any

00:04:59.160 --> 00:05:06.520
micro inside they use flow accelerator channels on the blades themselves which

00:05:04.320 --> 00:05:11.000
is there's lots of complicated stuff here generally

00:05:08.039 --> 00:05:14.000
speaking I am not an aerodynamic engineer I think you guys know this

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

00:05:17.720 --> 00:05:23.000
well regarded even by those who have very

00:05:20.720 --> 00:05:26.560
advanced Advanced Equipment for testing fans I know this because I spent some

00:05:24.800 --> 00:05:29.960
time using their equipment testing Noctua fans and they were just like yeah

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

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

00:05:35.360 --> 00:05:41.759
time on some of my quiet optimized systems and what I also know is that

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

00:05:44.000 --> 00:05:50.600
the static pressure and the deciel ratings there's more to it than that

00:05:47.840 --> 00:05:54.880
there's how gracefully does it undervolt so some fans yes you can undervolt them

00:05:53.039 --> 00:06:00.319
but they start to develop a grind or a tick that doesn't necessarily get picked

00:05:57.280 --> 00:06:02.520
up by a decimeter so so yeah you know

00:06:00.319 --> 00:06:06.840
it's there an audible noise but it's more about how annoying is that noise

00:06:04.319 --> 00:06:12.880
nocta fans don't make annoying noises they you know sure maybe they look kind

00:06:08.919 --> 00:06:12.880
of distinctive

00:06:12.960 --> 00:06:17.840
but that's their branding you can always

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

00:06:19.319 --> 00:06:27.160
radiators perfect for heat sinks oh yeah why is it perfect for radiators good

00:06:23.599 --> 00:06:29.720
question cuz nocta has 140 and 150 mm

00:06:27.160 --> 00:06:33.599
fans that use a round frame which is not for radiators because you'll lose the

00:06:31.319 --> 00:06:38.199
seal around the edges and in the corners like that which causes it to be less

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

00:06:39.800 --> 00:06:44.919
I'm just using it for illustration purposes gets to go right up against it

00:06:43.280 --> 00:06:48.919
and causes a seal so that pressure optimized design actually gets to push

00:06:46.720 --> 00:06:52.720
air through the fins of the rad or the heat sink rather than worrying about it

00:06:50.840 --> 00:06:56.560
spilling around the edges you can see an example of where this wouldn't matter in

00:06:54.520 --> 00:07:01.680
this computer right here come on in closer because here we're going to have

00:06:59.199 --> 00:07:05.280
leaks around the edges no matter what so as long as we have reasonably good

00:07:03.360 --> 00:07:08.960
directed air flow through the fins we're going to be fine so you could use

00:07:06.599 --> 00:07:14.400
something like their A5 instead of their A14 it wouldn't be necessary to have

00:07:10.879 --> 00:07:15.720
that square shaped uh fan Arrangement so

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

00:07:18.560 --> 00:07:24.599
with the advanced acoustic optimization frame stepped in inner surface micr

00:07:22.160 --> 00:07:28.280
structures so these flow separation from the suction sides which reduces reduced

00:07:26.680 --> 00:07:31.919
blade passing noise and improved air flow and pressure efficiency the anti

00:07:30.319 --> 00:07:35.199
vibration pads we covered running smoothness by

00:07:33.960 --> 00:07:39.199
eliminating torque variations and switching noises this is actually

00:07:37.479 --> 00:07:45.240
something that's uh that's really good to know about so guys the circuitry and

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

00:07:47.280 --> 00:07:54.159
pwm fans but they do have pwm fans these guys are makes a huge difference in

00:07:52.039 --> 00:07:58.919
using thirdparty fan controllers on fans so the more optimized it is and the more

00:07:57.520 --> 00:08:02.479
well the higher quality the components that are used the less likely you are to

00:08:00.599 --> 00:08:07.560
develop any sort of weird vibrations ticking or whining noises okay three

00:08:05.599 --> 00:08:11.520
speeds ultra low power consumption and six-year warranty metal bearing shell so

00:08:10.240 --> 00:08:15.120
Poss highest possible degree of manufacturing Precision minimum uh

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

00:08:18.960 --> 00:08:23.879
go quality fans yeah they're expensive but you get what you pay for thanks guys

00:08:22.560 --> 00:08:27.879
