00:00:00.160 --> 00:00:07.040
thanks to AMD packing a huge number of processing cores into their recent

00:00:04.720 --> 00:00:13.280
consumer cpus we are currently undergoing a big leap in the performance

00:00:10.400 --> 00:00:17.520
of home computers and consequently we're also undergoing a huge leap in the

00:00:15.679 --> 00:00:21.680
cooling requirements of the aforementioned

00:00:19.359 --> 00:00:26.480
this CPU is sucking

00:00:23.119 --> 00:00:29.760
over 500 watts

00:00:26.480 --> 00:00:31.599
which is why we have this

00:00:29.760 --> 00:00:36.160
the ice giant oh

00:00:33.280 --> 00:00:40.960
pro syphon elite and i know okay okay it doesn't look

00:00:38.800 --> 00:00:45.920
like much right now but stay with me here guys this

00:00:42.399 --> 00:00:48.960
is just a prototype and i i know it's

00:00:45.920 --> 00:00:51.600
kind of bulky but in our testing

00:00:48.960 --> 00:00:55.520
it actually managed to beat this

00:00:53.680 --> 00:00:59.920
ridge wallet is the sleek way to keep wallet bulge down with its compact frame

00:01:12.799 --> 00:01:19.040
to understand why this cooler is important we first need to talk about

00:01:16.320 --> 00:01:22.960
how CPU cooler designs have evolved as each generation has reached its

00:01:20.799 --> 00:01:27.920
theoretical performance limits we started with simple aluminum heatsinks

00:01:25.280 --> 00:01:33.600
on chips that output anywhere from 5 to 70 watts and they served us so well for

00:01:30.960 --> 00:01:39.119
so many years that you might think well if some little fins are good then more

00:01:36.479 --> 00:01:43.119
bigger fins must be better unfortunately it doesn't work that way as you get

00:01:41.200 --> 00:01:48.560
farther away from the original heat source along a fin the temperature of

00:01:45.680 --> 00:01:53.040
said fin will drop once that temperature gets near to the ambient temperature so

00:01:51.040 --> 00:01:57.759
the temperature of the air around it no matter how much longer you make the fin

00:01:55.360 --> 00:02:02.399
you will get no additional heat transfer from it

00:01:58.719 --> 00:02:05.759
so as modern cpus stretched into the 75

00:02:02.399 --> 00:02:08.319
to 150 watt range or even higher in some

00:02:05.759 --> 00:02:11.840
cases thermal engineers to turn to what at the time was a much more exotic

00:02:10.479 --> 00:02:19.920
cooling method heat pipes now a heat pipe doesn't inherently add

00:02:16.560 --> 00:02:22.800
more cooling to a cooler what it does do

00:02:19.920 --> 00:02:28.000
is transport heat much more efficiently than metal on its own by using both

00:02:24.959 --> 00:02:31.040
conduction and convection this is what

00:02:28.000 --> 00:02:34.239
allows massive heatsinks like the Noctua

00:02:31.040 --> 00:02:36.800
nhd15 to work effectively

00:02:34.239 --> 00:02:42.720
but we've got a problem under normal operation the fluid inside a heat pipe

00:02:40.000 --> 00:02:47.040
boils travels through the vapor chamber to the condenser end where the heatsink

00:02:44.800 --> 00:02:52.160
fins are attached and then is returned in liquid form to the heat source via a

00:02:49.840 --> 00:02:56.000
wick normally a sintered metal inner layer

00:02:53.040 --> 00:03:01.200
unfortunately if you pump too much heat into the system as you well might given

00:02:58.800 --> 00:03:06.879
AMD threadripper and Intel's high-end desktop chips these days can easily

00:03:03.200 --> 00:03:09.840
output 300 to 400 watts when overclocked

00:03:06.879 --> 00:03:14.400
you get what's called heat pipe dry out where the fluid isn't just turning to

00:03:12.159 --> 00:03:18.800
vapor in the vapor chamber but also in the wick causing it to not return to the

00:03:16.560 --> 00:03:24.959
heat source greatly increasing the thermal resistance of the heat pipe

00:03:21.599 --> 00:03:28.319
which brings us to thermosyphons and why

00:03:24.959 --> 00:03:30.560
this cooler right here is dope as all

00:03:28.319 --> 00:03:35.519
hell as the kids say instead of using a wick to transport the

00:03:33.280 --> 00:03:40.480
fluid back to the evaporator like a heat pipe a thermosyphon simply uses gravity

00:03:39.200 --> 00:03:45.280
and with a little bit of clever engineering this can be turned into a

00:03:42.799 --> 00:03:49.599
loop basically using the evaporation of the fluid as the pump all of this is

00:03:48.000 --> 00:03:53.920
nothing new though and it's actually pretty common in high heat output

00:03:51.680 --> 00:03:58.319
industrial applications the special sauce that ice giant has patented is

00:03:56.080 --> 00:04:03.120
some internal geometry here that allows the cooler to not just

00:04:00.879 --> 00:04:08.239
be mounted on your computer like this where you know gravity's effects are

00:04:04.560 --> 00:04:11.680
pretty obvious but also like this

00:04:08.239 --> 00:04:14.400
so in typical use this plate right here

00:04:11.680 --> 00:04:19.199
will contact your CPU the refrigerant inside will boil causing it to move up

00:04:17.120 --> 00:04:24.000
into the condenser somewhere in here where it will turn back into liquid and

00:04:20.959 --> 00:04:26.080
make its way back down to the evaporator

00:04:24.000 --> 00:04:30.880
this gives you in theory two main advantages one heat pipe dry out is

00:04:28.960 --> 00:04:35.360
avoided allowing for overclocking of super high performance chips and two

00:04:33.520 --> 00:04:39.840
since there's no pump involved the reliability is greater than a

00:04:37.280 --> 00:04:43.680
traditional aio like this one now ice giant couldn't say for sure what

00:04:42.000 --> 00:04:46.960
the reliability is and they're only planning for a six to seven year

00:04:45.360 --> 00:04:51.840
warranty but according to their simulations they figured this thing

00:04:48.960 --> 00:04:55.360
should last around 10 lifetimes give or take

00:04:53.440 --> 00:05:00.080
enough gibberdabber though let's give it a shot and see how it

00:04:57.520 --> 00:05:00.080
stacks up

00:05:05.520 --> 00:05:10.960
so as you guys can obviously tell from the current state of the mounting

00:05:08.800 --> 00:05:16.560
hardware the ice giant pro siphon elite is currently in the prototype stage of

00:05:14.160 --> 00:05:21.120
development but that's actually good news for a couple of reasons first and

00:05:18.800 --> 00:05:25.759
foremost of which is that the thickness of the unit is actually going to be

00:05:22.800 --> 00:05:30.639
decreased from 103 millimeters down to just 30 millimeters so that's less than

00:05:28.000 --> 00:05:34.800
a third and they figure they can do this without losing any performance this

00:05:33.120 --> 00:05:40.400
helps not just in terms of making the thing less ridiculously bulky and heavy

00:05:37.680 --> 00:05:43.199
but also in terms of performance because uh here we go

00:05:43.520 --> 00:05:50.880
it solves an issue where the fans would end up starved by a graphics card that's

00:05:48.560 --> 00:05:54.880
installed in the top slot here now one thing we expected was that the

00:05:52.720 --> 00:05:59.520
fans in the top of the case would help out the pro siphon a lot but it turns

00:05:57.680 --> 00:06:04.639
out they actually assisted our regular air coolers more

00:06:01.680 --> 00:06:07.199
now our prototype here is also only for thread

00:06:05.440 --> 00:06:13.520
but the final version is expected to have compatibility with lga 115x 2066

00:06:11.280 --> 00:06:16.800
and am4 and that's it

00:06:15.120 --> 00:06:21.440
the install process especially compared to an aio is pretty

00:06:19.280 --> 00:06:24.960
painless about the same as putting in a high-end air cooler so we've got three

00:06:23.280 --> 00:06:30.800
different profiles in here stock speed which is around 250 watts a 320 watt

00:06:28.240 --> 00:06:35.600
profile which is 3.6 gigahertz all core and

00:06:31.759 --> 00:06:37.759
400 watts yi mode which is uh 3.8

00:06:35.600 --> 00:06:42.720
gigahertz all cores on a 2990 wx so that is a 32 core

00:06:41.360 --> 00:06:46.880
processor let's go straight to that shall we now

00:06:44.720 --> 00:06:52.720
it should be noted that our fans are set to max speed on the CPU

00:06:49.440 --> 00:06:54.639
so you know well here goes nothing

00:06:52.720 --> 00:06:59.360
look at her go so hardware info has our package power

00:06:56.960 --> 00:07:02.479
reported at around 385 watts i can already feel

00:07:00.560 --> 00:07:06.000
the heat coming off the CPU just from the case fan at the back here

00:07:04.400 --> 00:07:14.960
and impressively our CPU temp so tdy is just 65 degrees

00:07:12.639 --> 00:07:20.080
that's gonna be tough to beat wow that is a darn impressive result we

00:07:18.960 --> 00:07:25.280
just just about cracked 71 degrees

00:07:23.680 --> 00:07:28.720
then again none of that is a surprise because we already ran a bunch of

00:07:26.960 --> 00:07:34.479
numbers in a more controlled environment before turning on a camera duh what is a

00:07:32.400 --> 00:07:41.199
surprise though is that our pro siphon prototype beat not only Noctua's thread

00:07:37.759 --> 00:07:42.160
ripper specific single tower cooler but

00:07:41.199 --> 00:07:47.280
even arctic's eight heat pipe dual fan

00:07:45.680 --> 00:07:50.720
monstrosity of a heatsink here

00:07:49.039 --> 00:07:56.080
so that's impressive but of course you guys have got to be

00:07:52.800 --> 00:07:59.280
wondering what about water cooling

00:07:56.080 --> 00:08:01.840
thing is unlike a heat pipe water

00:07:59.280 --> 00:08:07.199
doesn't have a point where it dries up in the CPU block or at least if

00:08:05.520 --> 00:08:12.879
it does you have much bigger problems to deal with so in theory our thermosyphon

00:08:10.560 --> 00:08:18.319
should get left in the dust but it doesn't

00:08:14.960 --> 00:08:21.319
so our Corsair h115i cooled system

00:08:18.319 --> 00:08:25.440
managed to thermal throttle at just

00:08:21.319 --> 00:08:28.400
320 watts though in Corsair's defense

00:08:25.440 --> 00:08:35.200
the h159i isn't made for a chip this size and doesn't cover the entire die

00:08:31.440 --> 00:08:36.560
as for our ek phoenix 360 well it didn't

00:08:35.200 --> 00:08:44.399
thermal throttle but shockingly it still lost and there's

00:08:40.560 --> 00:08:47.200
no excuse here because it's as bulky

00:08:44.399 --> 00:08:52.880
it's heavier we put a threadripper specific block on it and it even managed

00:08:50.000 --> 00:08:56.880
to make a comparable amount of noise if not more

00:08:54.480 --> 00:09:01.920
a note on that by the way ice giant is currently using delta fans that are as

00:08:59.680 --> 00:09:05.519
you guys can obviously hear far from quiet we're not sure if these

00:09:04.080 --> 00:09:09.040
are going to make it into the final product but they did say that they're

00:09:07.279 --> 00:09:14.240
going to be prioritizing extreme performance over acoustics so i'm not

00:09:12.080 --> 00:09:18.560
really expecting this to be a silent solution

00:09:15.600 --> 00:09:23.440
also guys i want to make it clear that we aren't ready to declare the ice giant

00:09:21.040 --> 00:09:27.200
pro siphon the best cooler we've ever tested because i would consider the two

00:09:25.760 --> 00:09:32.399
or so degrees of difference we've seen to be within the margin of error of our

00:09:28.959 --> 00:09:33.800
test and our measurement method and also

00:09:32.399 --> 00:09:38.160
guys we are working with a pre-production model we don't know if

00:09:36.399 --> 00:09:43.360
when they slim it down to a third it will actually perform exactly the same

00:09:40.800 --> 00:09:47.920
with that said i see a ton of potential here because the craziest thing about

00:09:45.519 --> 00:09:53.040
all of this so far is that the pro siphon elite here is still made of all

00:09:50.800 --> 00:09:58.560
aluminum for easier manufacturing at these early stages so in the future a

00:09:55.760 --> 00:10:04.000
potential v2 made out of copper could reduce temps a further 5 to 10 degrees

00:10:02.399 --> 00:10:07.920
though it should be noted of course that that's only applicable to these very

00:10:05.920 --> 00:10:12.240
high heat output cpus if you're running like a 9700k at stock speed or something

00:10:10.720 --> 00:10:16.399
you're not going to see that dramatic difference and i think they're going to

00:10:14.079 --> 00:10:20.880
have like a passive version for you guys bottom line then should you buy one of

00:10:18.240 --> 00:10:26.480
these well with the projected price of 130 to 150 dollars

00:10:23.760 --> 00:10:30.880
i guess i'd give it a pretty big i guess so if you want a top-tier cooler

00:10:29.120 --> 00:10:34.640
and don't mind this gigantic thing hanging off your socket

00:10:32.480 --> 00:10:39.839
like it is considerably more expensive than the air coolers that we looked at

00:10:36.720 --> 00:10:42.240
but it's cheaper and managed to

00:10:39.839 --> 00:10:46.399
outperform our aio meaning that there's probably an

00:10:44.880 --> 00:10:50.000
argument to be made for it so we're gonna have a link below to pre-order the

00:10:48.240 --> 00:10:53.839
production version or if you're in europe it'll be available on case king

00:10:52.079 --> 00:10:57.920
hopefully in the first half of 2020 although i did tell them i thought that that was pretty

00:10:56.720 --> 00:11:03.519
optimistic big thanks to katie from ice giant by the way for lending her expertise in
