Hello guys and welcome back to another video
of Architects3DP!
[2]
In this episode I’m gonna show you some
fans I bought a while ago, and I’m very
[7]
happy with the performance I’ve experienced
so far.
[10]
The fans are the noctua NF-A4x10 FLX and NF-A4x20
FLX.
[16]
Noctua did not sponsor this video, and I paid
for them the full price on amazon, so don’t
[23]
think I’m being paid for saying good stuff
about them.
[26]
I’m gonna make the unboxing of both models
and I’ll prepare an installation video in
[32]
the CTC Prusa i3 Pro B for next week, so you’ll
be able to compare the difference in the level
[35]
of noise produced by the printer before and
after installing them.
[36]
But before starting, make sure you are subscribed
to my YouTube Channel Architects3DP clicking
[38]
here in this little icon in the bottom right
corner of the video.
[41]
If you do it, you will help me creating new
content and growing the channel to reach more
[45]
special viewers like you.
[51]
Okay so as you can see I’ve bought 3 fans,
a NF-A4x20 FLX, and two NF-A4x10 FLX.
[59]
I’m going to use the 20mm one for the layer
cooling, and the two 10mm ones to cool down
[65]
the electronics and the nozzle.
[67]
As I said before I bought them from Amazon,
with a price of 12 euros ninety for the 10mm
[72]
version, and 15 euros thirty five cents for
the 20mm one.
[77]
Despite you can find very cheap alternatives
on amazon, ebay or other online shops even
[82]
from 1 euro, I’ve tested some, and they
work fine but after 1 or two weeks they start
[86]
making a lot of noise and so on.
[88]
With the Noctua ones, besides the incredible
performance, they offer a 6 years warranty,
[93]
what makes this small investment worth it
for a very long time.
[97]
Starting with the boxes, they come very well
packed and my first impression is that it’s
[101]
a high quality box made for a high quality
product.
[104]
If we continue with the NF-A4x10 FLX , we
can see that the box opens like a book in
[111]
both sides.
[112]
On the front it shows a view of the products
and all the included components on the right
[116]
hand side, and some sketches about the improved
design on the left.
[120]
The case opens on the back as well, where
they put a lot of information about the design
[124]
and the included components.
[125]
As a summary, the fans have flow acceleration
channels on the blades, what provides better
[131]
efficiency and lower vortex noise.
[134]
They also reduced the Motor Hub Size compared
to other 4mm fans, so the airflow and pressure
[139]
are significantly better.
[142]
The Noctua’s AAO frame will keep the vibrations
controlled improving low noise and performance.
[147]
Other features are the Stepped Inlet Design,
The Inner Surface Microstructures, and the
[152]
integrated anti-vibration pads, what together
will improve the efficiency, performance and
[157]
low noise of the fans.
[159]
In the right hand side they talk about the
new drive they use, the sealed bearings and
[164]
all the cable extensions included in the box,
but now we’re gonna see what’s inside!
[171]
After opening the box, the first we find is
a small transparent bag with something inside.
[176]
Once we open it we can see that it includes
an OmniJoin adaptor set.
[180]
With it we will be able to connect our fan
to any plug that our 3d printer uses.
[185]
With this adapter it includes 4 of what they
call 3M Stotchlok connectors, what is very
[190]
handy to join cables if you don’t want to
start welding.
[193]
Next we’ll find a 30 cm extension cable
that is properly sleeved and with a nice finish.
[199]
We of course can also find the nice Noctua
NF-A4x10 FLX fan that has a 20 cm properly
[206]
sleeved cable and a nice design as you can
see.
[210]
Next we’ll find what they call a Low-Noise
adapter, what is a properly sleeved cable
[214]
with a resistance that will reduce the RPM
of the fan from 4500 to 3700 and we are going
[221]
to use it to cool down the electronics of
the printer.
[224]
We also have the 3 to 2 pin adapter, one more
time properly sleeved and with a quality finish.
[230]
Another transparent bag with 4 screws to attach
the fan to the case, and finally the 4 anti
[235]
vibration mounts that you can use instead
of the screws, and will help reducing vibrations
[240]
as well.
[241]
As you can see a very complete packaging for
less than 13 bucks.
[245]
Jumping to the Noctua NF-A4x20 FLX fan, the
20mm version of the fan, we find a very similar
[252]
unboxing experience, with some difference
that I’m gonna detail now:
[255]
The information in the box is mostly the same,
with the difference that this one is twice
[260]
as thick as the 10mm version we saw before,
what will increase the static pressure performance,
[266]
making this fan ideal for demanding applications
with high flow resistance such as the fanduct
[271]
that I’m using for the layer cooling.
[273]
When we open the box, we find pretty much
the same stuff than before but we find some
[277]
different components.
[279]
The anti vibration mounts now are bigger,
since this fan is twice as fat as before.
[283]
The fan itself one more time includes a properly
sleeved 20cm cable, and you can notice how
[289]
wide this fan is compared to the 10mm version.
[291]
Then we find the same 30cm extension cord
and the same low-noise adapters that we found
[295]
in the 10mm version, but we also find a third
adapter called the Ultra-Low-Noise adapter.
[300]
With the original cable, the fan will spin
at 5000 RPM, while with the low-noise adapter
[302]
will reduce the RPM to 4400, and with the
Ultra-Low-Noise adapter the RPM will be reduced
[304]
to 3700, making it incredibly silent.
[308]
We’re not going to use this adapters since
we’re gonna need the full power for our
[312]
layer cooling but it’s nice to have them.
[314]
Finally we find the two transparent boxes
we opened before, with the 4 screws and the
[318]
Omni Join adapter set to connect our fan with
any plug that our board uses.
[323]
Okay so that’s it for the unboxing of this
amazing Noctua Fans.
[327]
You can actually use them in any 3D Printer.
[329]
If you make a quick research on thingiverse
you will find a lot of 3D Printed adapters
[333]
to install the fans in your machine.
[335]
In the next video I’ll install the 3 fans
in my CTC Prusa i3 Pro B 3D Printer and show
[340]
you the whole process that you can follow
for your machine.
[343]
I’ve added affiliate links to buy the fans
from amazon from every different country down
[348]
in the description, as well as the link to
buy the CTC Prusa i3 Pro B that I will install
[353]
the fans on, a 99€ 3d printer kit that will
get your 3D Prints out perfectly.
[360]
If you buy the items through the links you
will help the channel with a small percentage
[364]
of the price of the fan you buy.
[366]
Okay so buy lots of Noctua Fans and printers
from the links in the description because
[371]
that has been everything for this video.
