Wings Pro 4 fan this is a 120 millimeter
Corsair ml120 Pro LED fan and this is a
140 millimeter ncxt f-140 RGB fan they
all have one thing in common they're all
but there are many small differences
between fan models and in this short
video we're going to try to summarize as
many of them as we can I I might forget
a few but we're going to call it
comprehensive anyway here we go stay
with me to get rid of that annoying

let's kick things off with what I
believe to be the most important
difference between PC fans their sizes I
have 140 millimeter fan here and 120
millimeter here and these are the two
most common sizes you'll see even when
shopping for aios or just generic CPU
air Tower coolers they'll likely be
paired with either a 120 or a 140. and
this is an important distinction because
some cases only support 120s and some
support up to 140s and there are
advantages of going with larger fans the
two most prominent are airflow and noise
and these are actually trade-offs of
each other so if you're a fan of
spitting at a higher RPM obviously it's
going to make more noise but it's going
to displace more air if you lower the
RPM it's not going to be as effective as
a fan but it'll be a lot quieter a one
40 millimeter fan can theoretically
displace more air at the same RPM as its
120 mil counterpart here and this means
that it technically should have quieter
operation while being just as efficient
from an airflow perspective the only
issue with these again is that not all
cases and not all radiators support 140
millimeter fans take for instance this
fantastic XP 300 case you can see you
can clearly fit a 120 mil fan here but
we don't have any room for 140 mil fans
and that's just a consequence of a more
compact mid Tower like this we can
however fit 140s up front and that's
where I want to run a few tests so we've
got two be quiet light Wings fans here
the only difference between them is that
one is a 140 and one is a 120. we're
going to place both of these in that
same phantax p300 case and we're going
to run both at the exact same 1000 RPM
mark this here is the 120 millimeter fan
and this here is the 140 millimeter fan
foreign
a very clear difference I would say
another thing we can talk about while
we're here RGB it's a love it or hated
thing this trait blew up over the last
decade or so and that's why so many many
factors have included RGB options one
other good thing about these though is
that if you don't want to run any RGB at
all you can just turn it off something
else to look out for the type of RGB
supported in each fan this lightwings
fan from be quiet supports argb or
addressable rgbs meaning each individual
LED can act independent of all of the
others making for some pretty cool
effects the problem is a lot of older
boards don't support this feature here
meaning you might need to rely on a hub
these are their own can of worms I tend
to stay away from these wherever
possible and just wire my fans directly
into the motherboard on the RGB side
this Hub is not the worst I've seen they
do add clutter though and often rely on
their own RGB softwares to function
properly that's another can of worms now
some fans don't rely on any RGB at all
and these are super simple to not only
cable managed but maintained they don't
rely on any software and it's just one
cable to deal with so nice but a nice
middle ground for someone wanting very
simple lighting inside their build these
ml120 Pro LEDs come in various colors
this one has white LEDs baked in but
that's the catch you can't change the
color of these LEDs and they only have
one cable stemming from each fan so
they're easy to Cable manage they don't
require crazy RGB software or anything
like that but it's one color a static
color you might run into a case where
you have just like a rainbow fan or
something like that but it can't really
do much because again you don't have an
independent cable with an independent
controller but I like these these are
yeah a nice common Middle Ground here's
a good one three pin fans versus four
pin fans my hits referred to as voltage
fans versus pwm fans we have a dedicated
video by the way on pwm and how it works
you want to check that out it's in the
video description the gist of this
argument is that four pin fans while
they do often cost a bit more allow for
more flexibility in terms of RPM tuning
you might find three pin fans a bit
annoying and stubborn especially when
tuning with your your fancy fan tuning
software these things usually have a
voltage bottom and you can't really dip
below that without the fan completely
shutting off pwm fans by nature of how
they work can pulse power over and over
resulting in lower RPMs and much quieter
operation especially at idle and if
you're shopping for fans wondering how
you can tell the difference just look
for something along the lines of fan
connector you can see this one from ncxt
clearly says 4 pin pwm if it doesn't
specify this it likely is just a three
pin fan and is probably a bit cheaper
and again will be a bit more annoying to
tune now maybe you're shopping and
wondering why are some fans seemingly
more expensive than others even when all
the other traits we just discussed are
the same say they all have built-in RGB
say they're all pwm why are some fans 30
or 40 dollars and some are like 15 20
bucks well my friend there are some
interesting characteristics of Premium
fans you might not be aware of these
silent Wings Pro 4 fans are perfect
examples of value ads characteristics
and qualities that you might Overlook
while shopping online take for instance
this sweet little toggle here allows you
to choose between various RPM presets or
profiles without the need to download
any third-party software these are also
six pole motor fans which means six
magnets are involved in the operation of
this motor instead of your traditional
four means it can run quieter in theory
but it also means the price is going to
be a bit higher some fans come in packs
of three or six and this might actually
save you a bit of money per unit and
some fans just look plain weird or
awesome just different overall and you'd
expect that extra tooling to add to the
cost a bit but be diligent when it comes
to packs of fans some include hubs to
support things like RGB connectivity and
maybe just straight up power to each fan
it's nice to have all that kind of
centered again around one Hub but it
does add a bit of clutter and might
require the use of third-party software
some packs of fans don't come with any
Hub at all and it's kind of just a
you're on your own scenario but those
packs might also be cheaper as a result
and if you're foregoing a hub altogether
make sure that your motherboard has the
included RGB connector on board this is
a standard RGB header and this is
another addressable RGB header and you
can confirm which if either your board
has on your vendors page another
distinction you might come across while
shopping for fans is static pressure
versus airflow airflow fans just try to
move as much air as they can from point
A to point B and they're not worried
about what necessarily is behind them
you'll find airflow fans in a lot of
cases for example where there's a large
open space right behind each frame a
static pressure fan is usually
associated with either a CPU Cooler or a
radiator where again you've got a lot of
hindrance there right behind the fan
frame and so it's more important to get
that air forced through those small
little crevices and channels as
effectively and quickly as possible Silo
Wings Pro 4 fans have a very high CFM
you can see many different fan blades
they're curved very sharply these would
make for great case fans let's not say
they wouldn't be effective atop
radiators or next to CPU tower coolers
but they do the best job at just getting
as much air as possible from point A to
point B now compare this to a noctua NF
F12 this is a fan that ships in the
ryogen 2 360 and IO from Asus that I
showed you a few Clips ago this fan has
far fewer fan blades and the blades
themselves are shaped and just angled
much differently than they are in the be
quiet silent Wings Pro 4 fan and that's
because this has a much lower CFM and is
just targeted toward a different use
case CFM by the way is a measurement of
how much air a fan can displace over a
unit time and to be more exact CFM
stands for cubic feet per minute there
are also measurements of cubic meters
per hour that you'll find in a lot of
European countries and sure enough check
this out airflow on the back of the
silent Wings Pro 4 box 142.5 cubic
meters per hour and as for the noctua
93.4 cubic meters per hour that is a
vast vast difference but again not
really a reflection of how effective the
fan is in general they're both very good
and actually very expensive but the
Nokia fan is just slated for different
tasks it's going to be better for
radiators it's also going to be better
for Tower coolers the more you know
right I actually think this is a really
cool comparison here because these are
two giant factors of fans be quite
innocuous just make some of the best
available units on the market and these
are just very clearly different in terms
of their designs and noctua makes high
airflow fans as well and you'd expect
them to look a bit different than this
now before we wrap this one up consider
