00:00:00.080 --> 00:00:08.480
there are six 10 000 computers completely

00:00:05.120 --> 00:00:11.040
submerged in here like no really this

00:00:08.480 --> 00:00:16.480
entire rack is filled with a solution that cools better than water dissolves

00:00:14.000 --> 00:00:19.680
in water and it's absolutely 100

00:00:17.680 --> 00:00:26.320
safe but how can fellow canadians hypertech get away with dunking in this

00:00:22.400 --> 00:00:27.920
very expensive gear like their luke aka

00:00:26.320 --> 00:00:31.119
slick pc i'll tell you how

00:00:29.359 --> 00:00:36.800
right after i tell you about our sponsor MSI MSI's back-to-school sale is on now

00:00:34.559 --> 00:00:41.120
where you can save on laptops desktops and components there's also a giveaway

00:00:39.040 --> 00:00:45.640
to win some sweet prizes learn more at the link below or at the end of this

00:00:42.640 --> 00:00:45.640
video

00:00:52.480 --> 00:00:59.199
anyone who's been a fan of the channel will know that we've built several total

00:00:56.879 --> 00:01:02.800
immersion mineral oil pcs so like what's new here

00:01:01.440 --> 00:01:07.360
well this isn't mineral oil nor is it some

00:01:04.879 --> 00:01:11.920
flammable alternative this tank which is a show tank that's about half the actual

00:01:09.520 --> 00:01:16.400
length is filled with a dielectric or non-conductive mixture that's

00:01:14.159 --> 00:01:20.159
significantly lighter than most popular alternatives while also being better at

00:01:18.720 --> 00:01:24.080
conducting heat given that's pretty much its only

00:01:21.840 --> 00:01:28.960
purpose any improvement there is obviously welcome to add insult to

00:01:26.560 --> 00:01:33.680
injury the mixture is also a lot better for the environment it breaks down

00:01:31.280 --> 00:01:37.759
safely in water mineral oil by comparison is a petroleum byproduct with

00:01:36.000 --> 00:01:42.880
a laxative effect at best and is a carcinogen at worst i'm told that this

00:01:40.479 --> 00:01:46.159
mix is straight up safe to drink not that i really wanted to try it after

00:01:44.640 --> 00:01:50.240
being on the showroom floor for three days but i did end up getting some

00:01:48.399 --> 00:01:54.720
splashed into my mouth so i can tell you that it doesn't taste great that was

00:01:52.000 --> 00:01:59.840
warm also i tasted some i'm assured that it's not 3m's novak 649 as well

00:01:58.000 --> 00:02:05.119
that stuff likes to boil and is dangerous to inhale they wouldn't tell

00:02:02.000 --> 00:02:07.840
me what this stuff is exactly but it's

00:02:05.119 --> 00:02:12.560
also not a hydrofluoroethane like novak 7000 either

00:02:09.599 --> 00:02:17.040
your guess is as good as mine oh and they're making the chassis out of ocean

00:02:14.400 --> 00:02:20.560
recycled plastics by end of year as well at least that's what they hope to do but

00:02:18.959 --> 00:02:25.520
let's back up a sec server racks in data centers are already

00:02:23.280 --> 00:02:30.000
cooled by high-end air coolers and even liquid coolers so why are we even

00:02:28.319 --> 00:02:34.080
talking about this well there's a few reasons first and

00:02:32.080 --> 00:02:38.640
foremost this rack has zero fans and is basically silent by

00:02:36.480 --> 00:02:43.360
comparison it works by pumping the coolant through a loop to an exterior

00:02:40.879 --> 00:02:47.840
box that looks a bit like an hvac unit that box exchanges the thermal energy

00:02:45.360 --> 00:02:52.480
from the hot mixture to a cold water source in a single phase arrangement

00:02:50.400 --> 00:02:57.280
that means practically all of the noise it does make so the pump basically ends

00:02:55.200 --> 00:03:01.599
up well outside of the room because the installation doesn't require

00:02:59.360 --> 00:03:05.120
raised floors or bulky chiller units inside the data center it's relatively

00:03:03.599 --> 00:03:09.599
easy to retrofit into existing architecture what's more because all the

00:03:07.760 --> 00:03:14.800
heat is exchanged well outside of the rack the rack itself needs no hvac to

00:03:12.720 --> 00:03:20.400
cool it something we've struggled with in our own relatively tiny server room

00:03:18.080 --> 00:03:24.800
that means significant power savings because not only does hvac that's beefy

00:03:22.560 --> 00:03:28.560
enough to cool an entire server room or data center require a massive amount of

00:03:27.680 --> 00:03:35.519
juice so too to the high performance fans that you hear screaming inside of those racks

00:03:33.360 --> 00:03:39.760
hypertech claims a 30 to 40 percent reduction in cooling costs compared to

00:03:37.280 --> 00:03:44.720
hvac alone along with a 60 percent better hardware lifespan and to achieve

00:03:42.080 --> 00:03:48.879
that they painstakingly remove all of the fans from the hardware inside of the

00:03:46.560 --> 00:03:52.400
systems and replace their RPM sensors with sensors to monitor the temperature

00:03:50.319 --> 00:03:57.040
of the cooling solution as well as updating the BIOS to understand that

00:03:54.799 --> 00:04:00.720
this results in far less moving parts which are typically the most likely to

00:03:58.560 --> 00:04:03.920
fail all while retaining the original warranty thanks to their partnerships

00:04:02.319 --> 00:04:07.760
with hardware vendors like our good friends at NVIDIA

00:04:05.680 --> 00:04:11.680
speaking of NVIDIA they're part of the reason why hypertech is here to begin

00:04:09.519 --> 00:04:16.160
with with this immersion rack rumor has it that the upcoming newer

00:04:13.519 --> 00:04:20.000
generations of gpus and cpus alike are going to be designed to draw more and

00:04:18.079 --> 00:04:24.479
more power meaning that traditional cooling solutions will struggle to keep

00:04:21.759 --> 00:04:28.639
up without more exotic cooling solutions like hypertexts hypertech says that

00:04:26.720 --> 00:04:33.840
their solution can handle basically any load they can foresee up to nearly a

00:04:31.280 --> 00:04:37.199
hundred kilowatts and they can tailor the installation to meet the demand if

00:04:35.440 --> 00:04:42.560
for some insane reason that's not enough to dissipate all the heat your rack's

00:04:38.720 --> 00:04:44.240
blasting out or i guess soaking out

00:04:42.560 --> 00:04:48.720
now in a traditional data center the systems inside it generate a boatload of

00:04:46.479 --> 00:04:53.120
waste heat like effectively 100 of the electrical energy a computer consumes

00:04:50.880 --> 00:04:57.600
ends up converted to thermal energy or heat

00:04:54.560 --> 00:04:59.600
then we had to use even more electricity

00:04:57.600 --> 00:05:03.120
to get rid of said thermal energy which we call cooling now we've already told

00:05:01.840 --> 00:05:06.880
you how this takes the cooling electricity draw out of the equation but

00:05:05.280 --> 00:05:10.639
what if i told you that the heat electricity draw which there's no way

00:05:08.800 --> 00:05:16.320
around we need that for computers to work could be used for something else

00:05:13.919 --> 00:05:20.560
hypertech claims that 99 of the heat generated inside the loop can be

00:05:18.160 --> 00:05:24.000
captured as water they already have deployments that dump

00:05:22.400 --> 00:05:27.680
the heat into a building's hot water loops and in-floor radiant heating to

00:05:25.680 --> 00:05:31.199
either provide extra thermal capacity to those systems or even power them

00:05:29.919 --> 00:05:35.039
outright that works out to a significant energy

00:05:33.120 --> 00:05:39.600
savings because not only do you then not have to deal with hvac you're also not

00:05:37.600 --> 00:05:42.240
footing as big a bill for water boilers especially

00:05:40.720 --> 00:05:45.199
otherwise you'd have to upgrade a loop as your knees expand

00:05:43.919 --> 00:05:49.360
one thing you might be wondering at this point is

00:05:46.960 --> 00:05:53.759
aren't those ports submerged too and yeah i was wondering the same thing

00:05:51.520 --> 00:05:58.639
when we built our mineral oil pc we let the i o ports on the motherboard and GPU

00:05:55.680 --> 00:06:02.560
exposed but here all hardware maintenance is done with a dielectric

00:06:00.320 --> 00:06:05.600
mix already in the tank and that includes plugging and unplugging

00:06:04.560 --> 00:06:11.440
connectors i'm told that the mixture is thin enough that electrical connections can be made

00:06:09.039 --> 00:06:14.800
reliably although fiber optic cables need to be plugged into their sfp

00:06:12.800 --> 00:06:18.800
transceivers first because of how sensitive they are a thin film of

00:06:16.800 --> 00:06:21.840
dielectric is enough to prevent reliable transmission if you were to just shove

00:06:20.160 --> 00:06:25.280
it in there and speaking of shoving things in there like while you don't

00:06:23.600 --> 00:06:28.800
have to worry about dust build up as you do on traditional air cooling you're

00:06:27.280 --> 00:06:33.199
meant to work directly inside the dielectric so that means oils bacteria

00:06:31.600 --> 00:06:37.520
and yes dust particles will collect inside the loop from time to time

00:06:35.280 --> 00:06:41.120
that's where the loop itself comes in because the coolant is constantly

00:06:39.120 --> 00:06:44.639
cycling they can filter it later down the chain in the easy to access panel

00:06:42.880 --> 00:06:48.160
that makes cleaning much easier than a traditional rack where you'd have to

00:06:45.919 --> 00:06:51.440
dust them individually from time to time they told me you could theoretically

00:06:49.600 --> 00:06:56.000
drop a coffee in there and it'd be okay thanks to that filtration although i'm

00:06:54.240 --> 00:06:59.039
sure they wouldn't recommend trying it if you can help it

00:06:57.280 --> 00:07:03.199
under normal conditions they expect that the coolant will last for about 15 years

00:07:01.680 --> 00:07:08.560
this compared to the two phase coolers that are available now that use evaporation that need topping up every

00:07:07.360 --> 00:07:12.720
two years because they're actually losing the coolant and when the time

00:07:10.479 --> 00:07:16.400
comes for the solution to be recycled the solution can actually be

00:07:14.080 --> 00:07:18.800
reconstituted with a simple dialysis you don't even need to drain it and

00:07:17.599 --> 00:07:24.720
replace it on the show floor here they're trying to attract media companies with render

00:07:22.080 --> 00:07:27.160
farms that need massive GPU horsepower a full-size tank of one of these can

00:07:26.240 --> 00:07:32.560
contain 144 xeon render blades with gpus and

00:07:31.280 --> 00:07:37.199
with the stuff that NVIDIA has been showing off with photogrammetry and ai

00:07:34.639 --> 00:07:41.680
digital twin simulations it's becoming ever more important for some even

00:07:38.960 --> 00:07:46.400
smaller outfits that have access to that kind of compute if the TDP rumors are

00:07:44.000 --> 00:07:52.000
true of NVIDIA's upcoming rtx 40 series aka 8 and lovelace then achieving that

00:07:50.080 --> 00:07:55.599
will come at a significant cost to upgrade existing server racks and that's

00:07:54.000 --> 00:08:00.400
to say nothing of the environmental impact traditional setups will have not

00:07:58.160 --> 00:08:04.960
just running but cooling all of that extra hardware

00:08:01.919 --> 00:08:07.440
it's unorthodox but it might just be a

00:08:04.960 --> 00:08:11.840
crazy like a fox kind of situation that makes more sense the more you think

00:08:09.280 --> 00:08:15.120
about it maybe i can convince Linus to submerge our server room so we don't

00:08:13.440 --> 00:08:19.919
have to stop filming every time the door opens and maybe i can convince you to hear

00:08:17.599 --> 00:08:24.400
about our sponsor MSI MSI's back-to-school sale is on now

00:08:22.960 --> 00:08:29.680
looking for a new laptop for next semester they got those or what about a

00:08:27.199 --> 00:08:34.640
desktop pc that is totally for school and not for gaming mom i swear

00:08:32.320 --> 00:08:39.200
well you're covered there too and if you're into building your own pc they

00:08:36.000 --> 00:08:41.360
even have components on sale MSI is also

00:08:39.200 --> 00:08:47.440

and how you can win these prizes in the link below thanks for watching guys we

00:08:56.160 --> 00:09:02.160
don't typically cover siggraph but this year we felt we almost had to for more

00:09:00.399 --> 00:09:06.240
server room shenanigans go check out our end game storage solution of 270 hard

00:09:04.640 --> 00:09:09.519
drives oh right i guess that means that it can't be

00:09:07.839 --> 00:09:12.240
submerged oh well
