holy sh are you trying to tell me that
0:05
this box has a workstation PC sort of gaming
0:10
PC in it yes I am in fact it came all the way
0:17
from France and was sent to us by a company called calos who specializes in
0:23
silent cooling yes my friends cooling
0:27
with no fans no pumps no
0:32
water get the hell out of here oh
0:37
man there it is
0:45
and okay had no real chance of
0:48
extracting this thing on my own I'm going to go round up a poy we'll be
0:52
right
0:58
back
1:04
Mast drop is Now featuring the new flagship IM from dzat featuring a 6.8 mm
1:10
Dynamic driver check them out at the link in the video description so the
1:15
first thing I want to know is why couldn't I move this exactly how heavy
1:21
is this bastard so let's take it over to the scale here if you can help guide me
1:26
onto it yep okay wow
1:31
722 lb for this bastard 722 lb what kind
1:37
of what kind of bull crap is that like what is going on in here well let's have
1:42
a look at exactly what's going on in here so we've got a
1:46
5820k processor we've got four dims of
1:50
uh what is that yep hyperx Predator ddr4 memory we've got an MSI x99s SLI plus
1:56
we've got this is a 500 w superflower
1:59
passive power supply we've got an SSD and finally we've got a GTX 1080 but
2:07
none of that I mean especially given this is in an aluminum case it's not
2:11
even heavy none of that accounts for the
2:15
weight so the weight all seems to come
2:19
from cio's cooling solution so this is a
2:23
gigantic what looks and feels like aluminum heat sink all across the back
2:30
of the case here it's got to be about 2 and 1 half 3 in thick with these
2:34
gigantic fins and a secret sauce inside
2:39
that they specifically contractually forbidded me to open and
2:45
look closely at but the basic principle is on their site instead of what you
2:50
might normally use in a heat pipe which is sometimes even water they're actually
2:54
using a refrigerant called hfc 245 FAA
2:58
so this is Penta floan yes I had to look
3:02
at a cheat sheet in order to remember that they're using that along with these
3:07
uh these capillaries and you can actually see them here passing from the
3:11
heat sink over to the CPU area and then there'd be another one down by the GPU
3:14
so they're using these these presumably copper tubes that are carrying fluid
3:20
down the one side so that'll go in the
3:23
fluid side to the CPU block then what happens is it's evaporating here and the
3:28
vapor is going out this way now they're able to move it without a pump thanks to
3:33
a very similar principle to how heat pipes work and that is like these micro
3:38
pores in the metal itself how they keep it directional how they have it flowing
3:43
fast enough in order to achieve the temperatures they claim on their website
3:46
though that is still a mystery to me so
3:49
naturally I'm not just going to take their word for it but the basic premise
3:54
here is pretty straightforward calos is
3:57
using the same technology that got them 45 million of investment funding back in
4:06
2014 to take the technology that they
4:10
developed for data center cooling that
4:13
basically eliminates the problems with air that is that it's hard to direct the
4:18
heat somewhere that you want it to go and it's not as effective and the
4:23
problems with water which is that maintenance is an absolute Nightmare and
4:27
bring it to the desktop so no moving Parts no noise and they claim great
4:35
performance that's cool I mean I don't know how cool it is
4:40
it's really quiet though that's for sure so step one with my test bench Drive
4:45
installed is going to be to let it sit for like half an hour and idle because I
4:52
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
4:57
you know using a Word document for example
5:01
and that is not bad so the CPU is sitting around 39° the GPU is sitting at
5:07
around 30° but of course idle is not the
5:12
test of a cooling solution so the next
5:16
thing I'm going to do is throw up an Ida 64 test where we put it under load and
5:21
would you look at that 45 minutes later CPU still sitting at 67° on the package
5:28
and perhaps even more more impressively I mean these are like decent aircooler
5:32
temps perhaps even more impressively is
5:36
that the heat sink is handling that load with pretty much no difficulty
5:41
whatsoever so you can look at these thermal camera shots and see that even
5:45
our hottest point is well within what I would consider to be the comfort zone so
5:52
that leads us then to our last test
5:55
Crisis 3 I want to sit and run this game
5:59
game Let's Just Launch origin I want to run this game for 1 hour and see if it
6:07
can still hold up when we dump all that GPU heat load into the
6:12
system okay so uh we're back for the end
6:16
of our 1our GPU test although I should
6:20
probably point out that it's actually been 3 days though that's even more
6:23
impressive because check this out not only is our game still running let's
6:28
just yep not only is our game still running but it's actually still running
6:33
at 80 FPS which means that whatever The Thermals are of the rest of the system
6:38
it's at least not thermal throttling so I'm going to whip out the thermal camera
6:43
and get all the readings that I need in
6:46
order to put together kind of an after test for you guys so the GPU the
6:52
CPU memory uh I want that vrm solution that
6:58
like homemade vrm solution up there as
7:01
well as the power supply and finally I
7:05
want to get readings from the
7:08
back wow honestly I think this might be
7:12
the most impressive part the hottest point on this entire
7:17
finay here oh man I can barely move
7:22
it okay the hottest point on this entire
7:26
fin array is down here at about 40 4° so
7:30
to put that in perspective the entire thing like you can feel the heat coming
7:35
off it like an aura but the entire thing
7:38
is not so warm that it's uncomfortable to touch which is just mind-blowing
7:50
like okay we'll deal with that later in the meantime back to the system so I
7:54
first heard about this back in July there was a post on the Forum and it was
7:58
like oh these guys claimed to have a completely silent workstation I kind of
8:02
went ah yeah right this is always being claimed but as soon as you put a fan or
8:07
a pump in a system it is not silent and
8:10
for that matter even this one with no moving Parts in the cooling system is
8:15
not silent because you can hear a little
8:18
bit of electrical noise and like electrical switching noise in the power
8:22
supply even though this is nothing close to what I would consider to be coil wine
8:27
but what it is is phenomenally quiet
8:30
like to the point where you can only hear that stuff because it's so quiet
8:34
and even more impressively this is where
8:37
I really got shocked GPU Temps at 99% usage of 65
8:46
degre 65° CPU package temperatures of 55° it
8:51
not only is a silent cooler but it
8:57
actually outperforms most other cooling solutions that I have
9:04
seen Short of like high-end water
9:07
cooling with like a triple or quadruple
9:11
radiator of course though I don't entirely expect you guys to take my word
9:15
for it so I'm going to fire up my digital sound level
9:19
meter and let's fire up our
9:26
game okay so this tells us not a whole hell of a lot other than that when I
9:30
talk even from over here we see peaks of about 80 DB we need to get somewhere
9:36
quieter away from our server room what is this a computer I've never seen a
9:42
heat sink this Ballers it's like a car heat sink it's actually nothing like a
9:46
car heat sink car heat sinks have a very high fin per inch count we missing over
9:51
there why are these not aligned um there were any cats at the office they would
9:54
be all over this thing it's probably true it is not
10:00
just Gaff tape it just Gaff tape that on I can't GA tape it that won't work if
10:04
you don't go get the Gaff tape I will forget it let's just move it
10:08
okay I know that I'm having a great time where are we going okay but you're in
10:13
the wrong spot hey it is quieter back okay so at about 35 DB this is the
10:21
quietest spot in our warehouse so I'm going to plug the system in and power it
10:28
on and that made no difference whatsoever
10:33
okay well that's cool lus it actually works holy cow how do I get one um
10:39
that's kind of a complicated answer they say and I believe them because if you
10:43
look closely at their website this is clearly the exact same system that's in
10:47
all of their promotional materials that this is the only prototype in existence
10:53
right now I suspect this is just kind of like a weird side project for one of the
10:57
people who works there um but they do have
11:02
plans beyond the availability of this configuration if you buy a whole system
11:07
if you like contact them for pricing they do have plans to release something
11:11
in the future for they saying about 500
11:15
bucks for the cooler and a custom enclosure that you'd be able to
11:19
integrate your own system into and they figure that'll be
11:22
available sometime around CES of this
11:27
year but in the meantime
11:30
this is a very cool proof of concept and
11:33
a very heavy proof of concept and I hope
11:37
you guys enjoyed this episode of
11:40
holy a legitimately
11:44
fanless computer well there's lots of fanless
11:48
computers but this one has a GTX 1080 in it so thanks for watching guys if you
11:53
dislike this video hit that dislike button but if you liked it hit the like
11:56
button get subscribed maybe even consider checking out where to buy okay
12:00
