hello and welcome to tech deals do you
have an awesome powerful computer that's
just a bit too noisy would you like to
have a silent running computer the
solution could be as simple as a couple
of fans in today's video we're going to
be installing three nook Torah fans
to improve the noise volume or rather
reduce the noise volume of our $2,000
Cadillac build one case fan and the two
fans on the liquid cooler are what we're
replacing now this is a very nice
machine it overclocks nicely and at the
moment I have installed a Corsair H 100
IV 2 liquid cooler this is cool it does
a very good job of cooling that CPU but
coursers liquid cooler fans are not
silent they're quiet but they're not
silent now how important this is to you
depends entirely upon your personal
noise sensitivity
I'm very noice n sitive I like silence
furthermore this is going to be my live
streaming PC port which so I want a
completely quiet system so we are
installing these two 120 millimeter fans
onto that we're also replacing the rear
140 millimeter fan on the back it's a
blue LED fan I don't want a blue LED fan
I want a completely blacked out system
with no lights in it for when I'm
live-streaming so we'll replace that as
well to establish a baseline here's the
sound from the room with nothing on the
computer is completely off you can see
we're just under 43 decibels with the
system turned on we're just under 49
decibels this is with the stock cooler
master and Corsair fans on the liquid
cooler and in the case now a decibel
rating is fine but that doesn't account
for the war or pitch or tone of the
sound these fans aren't bad but they're
not great the knock Tora fans are great
and it really is worth replacing if you
want a completely silent system now you
can see the fans replaced you can see
the knock to our fans installed and
we've cut about half of the sound of the
system out we were just under 43 with
the system turned off we were just under
49 with the system turned on before now
we're at about 45 and a half most
importantly the systems
sounds much nicer we have our case open
and laid on its side and we have our
three fans here to 120 millimeter fans
which will replace our liquid cooler and
a single hundred and forty millimeter
fan which will replace the rear fan now
that fan is actually quiet enough but
the blue LEDs bother me I want no lights
anything this is a completely blacked
out system so we're replacing that fan
with this excellent one when it comes to
quality of packaging you just cannot
beat these things it includes multiple
ways of mounting including tooless
pushpins
there are several cables including a Wye
splitter included an extension cable and
this is really cool these fans are a max
1500 rpm but if you use this cable it
slows them down to a max 1200 rpm so
it's either fixed 1200 rpm or if it's
PWM connected to one of the four pin
connectors on the port then it's
variable with a max speed of 1200 so you
can either have a high performance or a
quiet fan all in the same packaging you
don't have to choose when you purchase
because the fan will do both jobs taking
the packaging out of the box I've said
before I'll say it again quality
products come in quality packages cheap
products come in cheap packages take a
look how nice this is here is an
extension cable there is the low noise
adapter I mentioned and then there is
the Wye splitter the nice thing is the
cable that is actually on the fan isn't
too long and they're sleeved in these
very nice quality black sleeves just as
a side note black nut Torah fans are now
available with colored tabs so you don't
have to get this color if you don't want
them the first step is to simply unscrew
the existing fan using a screwdriver
these four screws are actually the same
type that are included with the new fans
so we can reuse these we don't have to
use the new screws if we don't want to
and with those four screws disconnected
we simply unplug it and take it out of
the case I'll save this for use in some
other build where I do want a blue LED
fan when you install the new fan think
about where the power cables gonna go
where it plugs into the motherboard
because you can these are square you can
orient them in any of the
actions that you want and also think
about the intake versus exhaust the fan
generally blows towards wherever the
label is so as the fan spins it's going
to blow air in this direction because we
want this as an exhaust we want to put
it in this configuration the fan is now
screwed securely into place and we have
the power cable plugged into the
motherboard I am not using the extension
or the low power adapter that might
change in the future but for now I'm
just plugging it straight in I am now
going to change the top two fans on our
liquid cooler one of the things I love
about this case is the fact that these
screw mounts can be undone at the top
and we can remove the cooler without
having to access the rest of the system
this means that I can change the fans
without having to take everything out of
the case these Corsair 120 millimeter
fans are very effective at cooling they
are not silent and so the primary reason
to change these fans is because I want
silence we do want to reuse the existing
screws that came with the liquid cooler
because they are sized to fit into the
holes properly so we take the existing
Corsair screws and run them through each
of the holes and we just screw it right
back on and we take our second fan and
we simply put our Corsair screws through
it and we will screw that into place now
you can see that our two screen if our
two fans are screwed into place we take
our two cables and plug them into the
pump head no it does not matter that
these are not Corsair fans they're just
fans they're PWM fans the cooler does
not care and now we'll just reattach
everything even though these are thumb
screws still use the screwdriver to make
sure they're securely in place not too
tight just tight enough now to keep the
cables out of the fans and off the
system memory I am zip tying them off
yes I'm zip tying to the hose I am NOT
tying that tightly that there's actually
slack here this is not very tight this
is important never tie anything you see
how they're slides
never tie anything tight to these hoses
it's not ideal but it's really the only
place I have to tie it off make sure
it's slack because this way it's not
going to dig into the hose overtime note
I don't show it here but after doing the
sound test I went and changed the front
two fans with knocked or 140s it took
another decibel off the sound and
further improve the acoustics of the
machine so all five fans are now knocked
arose with the upgrade complete you can
now see that the sound volume has been
reduced but the actual decibel level is
not tremendously lower the biggest
difference is the pitch or the actual
frequency of the volume sitting here
next to this machine there is a
noticeable and perceptible sound
improvement versus the Corsair and the
Coolermaster fan that was installed it
is not massively quieter from a decibel
reading point of view it's much more
pleasant to listen to
and for me totally worth doing so if you
have an existing system that's just a
bit noisy or maybe the pitch or the
sound of the fans is not up to your
liking these knock tour fans are an
excellent choice they're about twenty
dollars apiece yes that's a lot for just
fans but they're very very well made
fans with wonderful accessories and easy
installation options you will find link
down in the video description below

fans go check them out and if you're
