holy sh are you trying to tell me that
this box has a workstation PC sort of gaming
PC in it yes I am in fact it came all the way
from France and was sent to us by a company called calos who specializes in
silent cooling yes my friends cooling
with no fans no pumps no
water get the hell out of here oh
man there it is
and okay had no real chance of
extracting this thing on my own I'm going to go round up a poy we'll be
right
back
Mast drop is Now featuring the new flagship IM from dzat featuring a 6.8 mm
Dynamic driver check them out at the link in the video description so the
first thing I want to know is why couldn't I move this exactly how heavy
is this bastard so let's take it over to the scale here if you can help guide me
onto it yep okay wow
722 lb for this bastard 722 lb what kind
of what kind of bull crap is that like what is going on in here well let's have
a look at exactly what's going on in here so we've got a
5820k processor we've got four dims of
uh what is that yep hyperx Predator ddr4 memory we've got an MSI x99s SLI plus
we've got this is a 500 w superflower
passive power supply we've got an SSD and finally we've got a GTX 1080 but
none of that I mean especially given this is in an aluminum case it's not
even heavy none of that accounts for the
weight so the weight all seems to come
from cio's cooling solution so this is a
gigantic what looks and feels like aluminum heat sink all across the back
of the case here it's got to be about 2 and 1 half 3 in thick with these
gigantic fins and a secret sauce inside
that they specifically contractually forbidded me to open and
look closely at but the basic principle is on their site instead of what you
might normally use in a heat pipe which is sometimes even water they're actually
using a refrigerant called hfc 245 FAA
so this is Penta floan yes I had to look
at a cheat sheet in order to remember that they're using that along with these
uh these capillaries and you can actually see them here passing from the
heat sink over to the CPU area and then there'd be another one down by the GPU
so they're using these these presumably copper tubes that are carrying fluid
down the one side so that'll go in the
fluid side to the CPU block then what happens is it's evaporating here and the
vapor is going out this way now they're able to move it without a pump thanks to
a very similar principle to how heat pipes work and that is like these micro
pores in the metal itself how they keep it directional how they have it flowing
fast enough in order to achieve the temperatures they claim on their website
though that is still a mystery to me so
naturally I'm not just going to take their word for it but the basic premise
here is pretty straightforward calos is
using the same technology that got them 45 million of investment funding back in
2014 to take the technology that they
developed for data center cooling that
basically eliminates the problems with air that is that it's hard to direct the
heat somewhere that you want it to go and it's not as effective and the
problems with water which is that maintenance is an absolute Nightmare and
bring it to the desktop so no moving Parts no noise and they claim great
performance that's cool I mean I don't know how cool it is
it's really quiet though that's for sure so step one with my test bench Drive
installed is going to be to let it sit for like half an hour and idle because I
want to know what kind of temperatures it runs at when we're not putting any kind of load on it like if you were just
you know using a Word document for example
and that is not bad so the CPU is sitting around 39° the GPU is sitting at
around 30° but of course idle is not the
test of a cooling solution so the next
thing I'm going to do is throw up an Ida 64 test where we put it under load and
would you look at that 45 minutes later CPU still sitting at 67° on the package
and perhaps even more more impressively I mean these are like decent aircooler
temps perhaps even more impressively is
that the heat sink is handling that load with pretty much no difficulty
whatsoever so you can look at these thermal camera shots and see that even
our hottest point is well within what I would consider to be the comfort zone so
that leads us then to our last test
Crisis 3 I want to sit and run this game
game Let's Just Launch origin I want to run this game for 1 hour and see if it
can still hold up when we dump all that GPU heat load into the
system okay so uh we're back for the end
of our 1our GPU test although I should
probably point out that it's actually been 3 days though that's even more
impressive because check this out not only is our game still running let's
just yep not only is our game still running but it's actually still running
at 80 FPS which means that whatever The Thermals are of the rest of the system
it's at least not thermal throttling so I'm going to whip out the thermal camera
and get all the readings that I need in
order to put together kind of an after test for you guys so the GPU the
CPU memory uh I want that vrm solution that
like homemade vrm solution up there as
well as the power supply and finally I
want to get readings from the
back wow honestly I think this might be
the most impressive part the hottest point on this entire
finay here oh man I can barely move
it okay the hottest point on this entire
fin array is down here at about 40 4° so
to put that in perspective the entire thing like you can feel the heat coming
off it like an aura but the entire thing
is not so warm that it's uncomfortable to touch which is just mind-blowing
like okay we'll deal with that later in the meantime back to the system so I
first heard about this back in July there was a post on the Forum and it was
like oh these guys claimed to have a completely silent workstation I kind of
went ah yeah right this is always being claimed but as soon as you put a fan or
a pump in a system it is not silent and
for that matter even this one with no moving Parts in the cooling system is
not silent because you can hear a little
bit of electrical noise and like electrical switching noise in the power
supply even though this is nothing close to what I would consider to be coil wine
but what it is is phenomenally quiet
like to the point where you can only hear that stuff because it's so quiet
and even more impressively this is where
I really got shocked GPU Temps at 99% usage of 65
degre 65° CPU package temperatures of 55° it
not only is a silent cooler but it
actually outperforms most other cooling solutions that I have
seen Short of like high-end water
cooling with like a triple or quadruple
radiator of course though I don't entirely expect you guys to take my word
for it so I'm going to fire up my digital sound level
meter and let's fire up our
game okay so this tells us not a whole hell of a lot other than that when I
talk even from over here we see peaks of about 80 DB we need to get somewhere
quieter away from our server room what is this a computer I've never seen a
heat sink this Ballers it's like a car heat sink it's actually nothing like a
car heat sink car heat sinks have a very high fin per inch count we missing over
there why are these not aligned um there were any cats at the office they would
be all over this thing it's probably true it is not
just Gaff tape it just Gaff tape that on I can't GA tape it that won't work if
you don't go get the Gaff tape I will forget it let's just move it
okay I know that I'm having a great time where are we going okay but you're in
the wrong spot hey it is quieter back okay so at about 35 DB this is the
quietest spot in our warehouse so I'm going to plug the system in and power it
on and that made no difference whatsoever
okay well that's cool lus it actually works holy cow how do I get one um
that's kind of a complicated answer they say and I believe them because if you
look closely at their website this is clearly the exact same system that's in
all of their promotional materials that this is the only prototype in existence
right now I suspect this is just kind of like a weird side project for one of the
people who works there um but they do have
plans beyond the availability of this configuration if you buy a whole system
if you like contact them for pricing they do have plans to release something
in the future for they saying about 500
bucks for the cooler and a custom enclosure that you'd be able to
integrate your own system into and they figure that'll be
available sometime around CES of this
year but in the meantime
this is a very cool proof of concept and
a very heavy proof of concept and I hope
you guys enjoyed this episode of
holy a legitimately
fanless computer well there's lots of fanless
computers but this one has a GTX 1080 in it so thanks for watching guys if you
