00:00:00.400 --> 00:00:10.160
so today i'll be doing a quick unboxing of a new fan from Noctua this is the nf

00:00:06.200 --> 00:00:13.120
p14flx now what the flx uh suffix

00:00:10.160 --> 00:00:18.480
denotes is that it is a flexible design so that means that the flx fan has three

00:00:15.360 --> 00:00:21.520
different speed settings which are

00:00:18.480 --> 00:00:22.880
1200 900 and 750 RPM and it achieves

00:00:21.520 --> 00:00:28.000
this through a few different adapters that are included with it other key

00:00:25.039 --> 00:00:31.359
features of this 140 millimeter fan are the impeller with vortex control notches

00:00:29.920 --> 00:00:34.960
and we'll show you those in a minute the metal reinforcements which allow the

00:00:33.440 --> 00:00:40.399
blah blah blah ultimate manufacturing precision high durability and vibration

00:00:37.200 --> 00:00:42.320
free running as well as a round frame

00:00:40.399 --> 00:00:45.360
now the round frame of this fan is what makes it so special and we'll get to

00:00:43.520 --> 00:00:49.280
more about that in a minute this has their updated drive bearing um it has

00:00:48.079 --> 00:00:52.640
the sso bearing with the smooth communication drive too ensure super

00:00:51.360 --> 00:00:59.680
running and smoothing by eliminating torque variations and switching noises etc etc basically it's a fan but what

00:00:57.199 --> 00:01:03.680
makes it special is what we are about to get to here in just a moment so let's

00:01:02.160 --> 00:01:09.360
have a look at the accessories that are included with the nfp 14 flx

00:01:06.960 --> 00:01:14.320
and first we have four rubber fan mounting grommets so rather

00:01:12.000 --> 00:01:18.720
than using screws which can transfer vibration directly to the case Noctua

00:01:16.960 --> 00:01:22.640
fans use these little rubber mounting grommets these are quite common

00:01:21.119 --> 00:01:26.479
but they're only really included with higher end fans or you have to buy them

00:01:24.240 --> 00:01:30.000
separately next we have two

00:01:27.280 --> 00:01:34.000
low noise adapters so one is the low noise adapter and one is the ultra low

00:01:32.320 --> 00:01:38.720
noise adapter so all you do is plug these in in line with the fan and they

00:01:35.759 --> 00:01:42.159
will make it run at a slower RPM next we have four metal mounting screws

00:01:40.720 --> 00:01:45.920
you can't always use those rubber grommets and sometimes good old-fashioned mounting screws are what

00:01:44.720 --> 00:01:51.759
works best and then we have

00:01:48.399 --> 00:01:55.840
ah adapters so these are 120 millimeter

00:01:51.759 --> 00:01:59.040
to 140 millimeter adapter but wait Linus

00:01:55.840 --> 00:02:02.320
you said this was a 140 millimeter fan

00:01:59.040 --> 00:02:04.960
well it is because of the round frame

00:02:02.320 --> 00:02:10.319
they're actually able to make this 140 millimeter fan compatible with 120

00:02:08.239 --> 00:02:14.400
millimeter mounts you can see if you had a square frame going around these holes

00:02:12.720 --> 00:02:18.879
you'd have substantially less room for the fan so Noctua's engineers

00:02:16.640 --> 00:02:23.120
ingeniously decided to make it work this way so all you have to do is attach the

00:02:21.200 --> 00:02:27.200
little metal bracket and you can see that that makes it a little bit wider a

00:02:25.440 --> 00:02:32.160
little bit further out so you can just attach it to a 140 millimeter hole or to

00:02:29.760 --> 00:02:35.360
a 120 millimeter hole very cool now the vortex control notches are what we'll

00:02:33.840 --> 00:02:39.280
talk about next here and let's just have a quick look at the fan here so you can

00:02:37.360 --> 00:02:43.840
see that they're offset we've got two notches here at the edge of the blade we

00:02:41.920 --> 00:02:48.400
have two notches here at the middle of the blade and two notches here closer to

00:02:46.000 --> 00:02:53.120
the center of the fan now what that means is that the way these disrupt the

00:02:50.319 --> 00:02:57.280
airflow is supposed to be more even overall because they're offset this way

00:02:55.280 --> 00:03:00.800
versus having all of the blades shaped exactly the same way Noctua has been

00:02:59.200 --> 00:03:04.720
doing this on all of their fans for quite a while now and obviously they're

00:03:02.879 --> 00:03:08.560
very very well regarded fans because people pay very good money for Noctua

00:03:06.879 --> 00:03:13.680
fans now another thing they've got called out here is the metal reinforced

00:03:10.560 --> 00:03:14.640
sso bearing shell and magnet so that's

00:03:13.680 --> 00:03:20.400
uh kind of cool i suppose okay it comes with a sleeved three pin connector and

00:03:18.800 --> 00:03:24.959
the last accessory is probably something i should have mentioned before and it is

00:03:21.840 --> 00:03:26.640
a three pin to molex connector so you

00:03:24.959 --> 00:03:30.560
can power this thing any way you want you can power it at any speed you want

00:03:28.400 --> 00:03:34.560
and you can mount it any way you want thank you for checking out my unboxing

00:03:32.640 --> 00:03:37.560
and product overview of the Noctua nfp14flx

00:03:38.239 --> 00:03:45.680
okay that wasn't really the end i've re-boxed the fan already but what i noticed when i was re-boxing it is this

00:03:42.959 --> 00:03:50.879
little tab right here in huge bold face type so that i couldn't possibly miss it

00:03:47.840 --> 00:03:53.280
says open and we can actually open up

00:03:50.879 --> 00:03:57.360
this uh this merchandising thing on the back of the fan so we can find out

00:03:55.360 --> 00:04:02.159
exactly how the vortex control lodges work because my explanation was just

00:03:59.840 --> 00:04:06.239
terrible okay so standard trailing edges can produce rotating pressure fields and

00:04:04.480 --> 00:04:10.080
vertices that cause audible noise at distinct frequencies this un this

00:04:08.400 --> 00:04:14.480
undesired tonal noise is much more annoying than noise that spread over a

00:04:11.760 --> 00:04:19.759
broad frequency range so that is what the vortex control notches do they make

00:04:16.959 --> 00:04:23.360
it split into several smaller vortices and the noise is spread over a wider

00:04:21.440 --> 00:04:27.520
range of frequencies and is therefore much less perceptible so there you go

00:04:25.759 --> 00:04:34.320
thank you for checking out my unboxing and my little add-on about the nf p14
