Linus Tech tips coverage of computex 2013 is powered by Western Digital our
trusted gaming gear partner is Corsair Vengeance and our trusted retail partner
is nc.com now we talk about Noctua products
a lot but they don't really released that many new products all at once for
the most part but we've got Jacob here from nocta to tell us about a whole
bunch of crazy stuff that's going on in their Booth so why don't you tell us
about these yellow fans first yes it's with pleasure first of all uh the yellow
color is just because they are CNC mockup prototypes uh they will have the
normal noctur color when they're ready they are new additions to our Aeries
fans uh we had 140 92 slim 60 and 40 in
the past and these are going to be 20 cm 92 mm uh with 25 mm thickness and 80 mm
uh they will have all the features of the a series you already know like flow
accelerations channels or sso2 bearings
awesome so basically we're getting updates to a couple sizes that we
haven't really seen before and that we're kind of doe for an update
yes exactly now speaking of usual noct to a color schemes who what is this
these are black fans targeted for industrial customers uh they are made
from fiberglass reinforced polyamid which is even more rigid than the
fiberglass reinforced PBT we normally use they will also come with IP class 52
water and dust protection and a new six pole motor design so why do we need a
six pole motor design what's the difference between this and the four
pole here the uh improvements of the six pole motor design are that it offers
even smoother running even lower vibrations and even lower power consumption all right let's move on to
heat sinks how did I manage to miss this project Redux this is exclusive if I
don't get the exclusive thing I'm not even doing my job Jacob why what's
project Redux yeah this is for all the people whoever wanted a noct fan but
felt it's just too expensive we'll take some of our most popular models like the
NFS 12b or NFP 14 streamline the
packaging and make them available at uh quite a bit more affordable prices very
cool now being a design and engineering company first and foremost and a
marketing company second most uh Noctua just calls this prototype dtype CPU
Cooler uh but what's cool about this is it stays out of the no zones for your
CPU socket it stays away from high-profile memory heat sinks and it
also gives you the same cooling surface area and performance as something that
previously took up a lot more space by simply using their new 92mm fan design
right down the middle so this will be coming at some undisclosed date because right now it doesn't even have a name
yet moving right along they've improved compatibility for their low profile
coolers you check this out so they basically cut away a little piece here
on the side that allows for things like
this High capacitors that are next to the PCI Express lot so you can use these
easily in either an AMD or Intel miniitx
configuration now it has well kicks out a fair bit of heat so they're also
adding a higher performance ITX cooling solution that is still low profile
enough that it sits easily next to a half height PCI Express graphics card
and doesn't interfere with your full height DDR3 memory modules it also is
designed to stay out of the way of your four pin connector as well as your SATA
connectors the last thing that we have to show here is the fact that this is
not new at all this is the original noock to a CPU Cooler the u12 or
something like that doesn't matter what it's called anymore you can't buy one but it still has well compatible with
updated mounting hardware and you can still get a free mounting kit if you are
KN to a customer and you provide proof of purchase now Jacob I ran through all
that really quickly because honestly this is going to be the star of the show right here tell me what this guy is
because it's like check this out this goes back to my NHD 14 unboxing where I
held it up and I'm like it's the size of my head this is the size of my head
again yeah it's actually an update uh long expected and awaited update to our
popular NHD 14 um we've working really
hard to further improve performance and the way we did it is that we expanded
the width to 150 mm to fit the new NFA
15 fan and at the same time we've also increased spacing between the Heat pipes
so we've now got a better heat distribution over a larger surface area
and this allowed us to really provide a nice additional performance boost
compared to the original D14 now the original D14 had some compatibility
issues from time to time with high-profile memory uh and this if being
even wider how do you address that yes
we've H we have these little cutouts here and uh if you drop the front fan
you can actually install RAM modules with up to 70 mm height so uh if you're
willing to sacrifice a tiny bit of performance uh this cooler gives you
actually more flexibility uh as far as high uh RAM heat spreaders are concerned
than the original NHD 14 so here's a look at the uh the cutouts so those
cutouts are on both sides meaning you can flip it around you don't have to
worry too much about oh I I put it on the wrong way so yeah don't worry too
much about that also help on LGA 2011 where there's RAM on both sides ah when
there's RAM on both sides sorry I was holding the microphone there so if you have RAM on both sides then you'll be
able to have clearance on either side now let's move into the Space Age stuff
that totally doesn't exist yet now my understanding is noct TOA had to take
possession of one of the largest Austrian diamond mines in order to
create this new technology tell me what the devil makes this so much more
special than what we've already seen as base plates for CPU heat sinks I'm going
to try and show them that sparkle there what makes this base uni is that it has
a copper Diamond composite insert so uh
inside the copper base we have an insert made from a composite material that
features a thermal conductivity of 500 watts per meter Kelvin which is roughly
25% more than pure copper okay so why uh
why aren't we doing this already what what does it do well the benefit of it
it is as we uh sh this uh these simulation outputs here is uh that we
get a better heat distribution across the base so we get more heat to the
outer heat pipes and can make and we can make them work more efficiently the
reason why we haven't uh been doing anything like that so far is that the
the hot pressing technology needed to make this type of material is brand new
and it's very expensive so I cannot really say whether we will actually make
it to the market with this one yet now if you make a base out of powder how is
that going to even be held together um
first of all it's uh pressed together by hot pressing so it forms a solid
material but we also need uh the copper like wrapped around it to make it really
solid and to allow us to nickelplate it and solo the heat pipes to it like we
usually do there you go guys performance isn't always about looks as Noctua has
proven to us time and time again but this my friends if you've
hungen with us this long is the voodoo magic that's going on a fan with active
noise cancellation technology so why don't you first explain what ISC the
basic principle behind a ANC is that you use one Soundwave to cancel out another
Soundwave by overlapping so this will be a z d CPU Cooler uh well in theory yes
in practice unfortunately that's not possible the main reason for this is
that the wave fans emit noise is just so complex they produce rotating pressure
fields and in order to do active noise cancellation on that you have to exactly
match these rotating pressure Fields so how do you even get close what are you
guys doing to make a fan make noise and
make anti-noise at the same time well the brilliant thing about the rotto sub
technology that we're using is that we actually employ the fan impeller to
create the anti-noise signal now the way this works is that we have a coil inside
the fan frame and a magnet sitting inside the blade tips and when we switch
on the coil we can pull down the blade tips just ever so slightly and when we
switch off the coil again they go back up so does this create additional
vibration when the Fan's spinning that can be transmitted to your case no it
doesn't because most of the fan vibrations unless the fan is broken uh
comes from the blades passing over the struts and these are exactly the
pressure fluctuations we're canceling out with the active noise control as
well so there's going to be products at some point maybe you know it'll be a
while in the future but this fan what's the challenge building a radiator fan
that uh uses this active noise cancellation technology the challenge
we're facing with radiator fans is that there are just so many types of
different radiators different frang grills Etc um basically the controller
we're working with and the logic working inside the controller is designed to be
self- adaptive and self-learning uh but we're still seeing better results when
we can somewhat control the environment all right now show us what controls the
environment better and an entire self-contained Noctua cooler that uses
this technology and tell us about this cooler yes in this case we have the fan
sitting in between the fin Stacks it's a similar design as the popular NHD 14 and
in this case we know exactly uh the distance between the fan and the fin
stacks and what will occur when the fan will hit the he uh the the the air
coming from the fan will hit the heat SN fins okay show us your demo here and
they're going to have to rely on this graph but we've heard it it actually
works so there's a microphone inside the case this whole thing is toolless so you
actually Slide the entire assembly with the fan in the middle into place after
you've already installed the cooler you no longer you said you're able to get
pretty similar performance to that double stack cooler over there with the
Shroud and with a single fan instead of two fans making it lower profile and
check out this that is the microphone that goes into the actual so there's
actual logic built into your CPU Cooler now which is absolutely fantastic so
guys we are going to have Jacob press the switch and turn the active noise
cancellation on and off and we're going to direct your attention to this little graph over here so this is showing
actually here if I if I tap on the back of the
case hold on if I yell on the there we go you can see my voice right there if I
stop
talking ah okay so you can see the microphone is working now go ahead and
turn active noise cancellation on and off I'm going to I'm going to stop talking we're going to see if they can
figure it out
there's a lot of ambient noise here I guess I'm sorry but you guys are going to have to kind of take my word for it
what it does is it eliminates that that
noise it doesn't make the fan completely silent but you know how you often talk
about different characteristics of fans where a deciel meter doesn't necessarily
tell the whole story because it just tells you the sound pressure it doesn't
tell you if it's a low hum or whether it's an annoying kind of noise like that
so this it works and it's extremely exciting when can we buy one well
there's uh still a lot of challenges we face in manufacturing because it's uh of
vital importance to get everything uh lined up very precisely uh because the
risk with this kind of technology is that if you're just off by 0.1 or 0.2 mm
if the sound waves don't overlap exactly as you want you will end up creating
more noise than you originally had so we
have to make sure that everything is just super precise in manufacture in and
I think if I think if everything goes very smoothly uh we could have a product
ready on the market in spring 2014 or
maybe for next computex wonderful so guys thank you so much to Jacob for
joining us here it's a pleasure don't miss any of our computex 2013 coverage
