as you guys probably know I'm a huge fan of noctu a fan so I'm super excited to
check out the NF A14 flx now as you know
we've got a wide variety of different 120 mm cooling fans available from nocta
including their FS series and their P series which are optimized for radiators
and heat sinks because they're very pressure optimized with the F series The
F12 actually having a directed Cyclone
of air coming away from the exhaust side of it now this doesn't have that
functionality but this is a 140 mm version of what would be very similar to
a p12 fan but with some additional technology so if you come in here and
have a look at the actual features that are available on it we've got a square
140 mm frame this makes it ideal for Cas
in r ah yes well you can see nocta puts
right here what what it's for case and radiator cooling flow acceleration Chann
AO frame stepped Inlet design inner surface micro structures integrated anti
vibration pad smooth commutation drive to basically what noct was trying to say
is their drives are engineered to the point of it being kind of obsessive so
come in here and have a look at the uh fan itself and the accessories so unlike
the 120 mm fans the 140 mil fans come
with not only a low noise adapter low noise adapter right there which uh down
volts the fan to 7 volts but also an
ultra hold on a second okay well one of these is ultra
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
three pin adapter very nicely sleeved all of them right up to the connector so
you're not going to see any unsightly colored wires we've also got extension
cables this is fantastic see just a simple three pin extension cable
mounting screws although usually you won't use those you'll use the rubber
ice ating antivibration mounts I mean you can though because
you've got more antivibration mounts here the only problem with using the
metal screws is because they have to drive into hard plastic and they will
transfer some vibration to the case that way even with these rubber isolators so
if you use these rubber isolators up against the case with these rubber
isolators Bridging the hard plastic with the hard metal of the case itself then
you've got no room for vibration to be transferred from the fan to the chassis
when it's spinning not to say that KN to a fans actually create a whole ton of
vibration when they're spinning because they really don't the fans all come with
short cables love this because it means that no matter where you install them I
mean really a case is only so big usually where you install it there's
going to be a fan header somewhere nearby if there isn't they've included
the extension that you need to run it wherever it needs to go that makes it
more like a normal fan wire length love
this too check this out this is a newer feature that they've started adding to their fans see these right here I
couldn't figure out what they were for at first I thought they were just for
sort of mounting the uh the rubber noise isolators then what I realized is these
are probably for cable management check this out so whenever you you know when
you wrap a wire around the outside of a fan maybe they're not for that but
whatever you can use them for that all you got to do is put them under these
little rubber pieces and they will generally stay there very very cool
stuff like you know when you take a fan and you mount it kind of like here at
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
that so I want you to have a closer look at these rubber isolators you can remove
them if you want you don't have to keep them on you know say in the odd case
that it causes some kind of a compatibility issue with your case or your cooler or anything like that you
don't have to worry about it so let's have a look at some of the technologies
that NOA builds into the fan number one is the six-year warranty um so basically
what they're saying is 150,000 hours or
something like that is the meantime between failure for this thing and yeah
there you go meantime between failure of greater than 150,000 hours so they're
pretty much saying yeah it's not going to die but if it does we'll deal with it
without adapters it runs at 1200 RPM with an adapter this is the wrong fan uh
with an adapter this one also runs at 1200 RPM but low noise adapters at 1050
ultra low noise at 900 RPM so at 900 RPM
this thing will be darn near
silent all right technology wise these guys right here these stepped inlets
apparently reduced the amount of noise that is here we go stepped Inlet design
stepped Inlet design is Advanced aerodynamic design blah blah blah with
first with the F12 the F12 was one of their most advanced fans ever by adding
turbulence to the influx facilitates the transition from laminer turbulent flow
so similar to The dimple structure of the golf ball leads to better flow
attachment to the frame which allows the impeller to suck in more air and helps improve overall air efficiency they also
use a very Advanced bearing that is completely sealed so you won't get any
micro inside they use flow accelerator channels on the blades themselves which
is there's lots of complicated stuff here generally
speaking I am not an aerodynamic engineer I think you guys know this
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
well regarded even by those who have very
advanced Advanced Equipment for testing fans I know this because I spent some
time using their equipment testing Noctua fans and they were just like yeah
they're they're really good fans they're they're just really good um I do know
that they last over the long term I've been using Noctua fans for a very long
time on some of my quiet optimized systems and what I also know is that
they're darn silent now guys there's more to it than just the RPM the CFM and
the static pressure and the deciel ratings there's more to it than that
there's how gracefully does it undervolt so some fans yes you can undervolt them
but they start to develop a grind or a tick that doesn't necessarily get picked
up by a decimeter so so yeah you know
it's there an audible noise but it's more about how annoying is that noise
nocta fans don't make annoying noises they you know sure maybe they look kind
of distinctive
but that's their branding you can always
tell a no to a fan when you see it so this guy right here perfect for
radiators perfect for heat sinks oh yeah why is it perfect for radiators good
question cuz nocta has 140 and 150 mm
fans that use a round frame which is not for radiators because you'll lose the
seal around the edges and in the corners like that which causes it to be less
efficient this way the fan gets to go right up against this is a 120 mil rad
I'm just using it for illustration purposes gets to go right up against it
and causes a seal so that pressure optimized design actually gets to push
air through the fins of the rad or the heat sink rather than worrying about it
spilling around the edges you can see an example of where this wouldn't matter in
this computer right here come on in closer because here we're going to have
leaks around the edges no matter what so as long as we have reasonably good
directed air flow through the fins we're going to be fine so you could use
something like their A5 instead of their A14 it wouldn't be necessary to have
that square shaped uh fan Arrangement so
let's just make sure we don't miss any of the other Technologies they include so we got the flow acceleration chance
with the advanced acoustic optimization frame stepped in inner surface micr
structures so these flow separation from the suction sides which reduces reduced
blade passing noise and improved air flow and pressure efficiency the anti
vibration pads we covered running smoothness by
eliminating torque variations and switching noises this is actually
something that's uh that's really good to know about so guys the circuitry and
the design of the of the fan motor as well as the pwm or actually these aren't
pwm fans but they do have pwm fans these guys are makes a huge difference in
using thirdparty fan controllers on fans so the more optimized it is and the more
well the higher quality the components that are used the less likely you are to
develop any sort of weird vibrations ticking or whining noises okay three
speeds ultra low power consumption and six-year warranty metal bearing shell so
Poss highest possible degree of manufacturing Precision minimum uh
tolerance and excellent long St stability CNC mil bearing shell made entirely from breast okay so there you
go quality fans yeah they're expensive but you get what you pay for thanks guys
