00:00:00.320 --> 00:00:10.240
frankly i'm not even 100 sure where to start with this one meet

00:00:04.960 --> 00:00:11.840
a data's spectrex d80 ddr4 memory as

00:00:10.240 --> 00:00:20.720
they're calling it the world's first RGB ddr4 memory with

00:00:16.720 --> 00:00:23.439
hybrid liquid air cooling system

00:00:20.720 --> 00:00:28.800
using a combination of a liquid heatsink and an aluminum heatsink to deliver

00:00:25.920 --> 00:00:35.760
effective thermal cooling water cooled memory

00:00:32.399 --> 00:00:37.200
welcome my friends to [ __ ] manufacturers

00:00:35.760 --> 00:00:40.079
say this

00:00:38.800 --> 00:00:44.160
this is water-cooled memory

00:00:42.239 --> 00:00:48.399
throughout this video Linus will refer to the liquid as water this is

00:00:45.920 --> 00:00:52.559
inaccurate the liquid is in fact 3m novak however Linus is having some

00:00:50.800 --> 00:00:58.440
well-deserved time off making a vocal correction impossible so here i am rock

00:00:55.280 --> 00:01:01.490
you like a hurricane here i

00:01:04.400 --> 00:01:11.840

00:01:20.720 --> 00:01:26.400
description well we're off to a good start the shutdown button doesn't work

00:01:24.720 --> 00:01:29.759
brilliant who needs to shut down their computer anyway

00:01:29.759 --> 00:01:32.880
what am i supposed to do

00:01:32.960 --> 00:01:38.159
now i could just chart all over this stuff based on

00:01:36.720 --> 00:01:42.880
pure principles of cooling theory because i

00:01:40.720 --> 00:01:48.960
actually don't need to plug them in in order to know that the water cooling on

00:01:45.600 --> 00:01:51.280
them is really not doing anything but i

00:01:48.960 --> 00:01:56.799
at least try to take manufacturers claims somewhat seriously i want to give

00:01:53.439 --> 00:01:59.439
them every opportunity to prove me wrong

00:01:56.799 --> 00:02:02.960
here so what i'm going to do is devise an experiment one thing's for sure they

00:02:01.759 --> 00:02:11.039
look pretty cool other than that they have a red heat spreader on an RGB RAM module on a more

00:02:07.280 --> 00:02:13.840
positive note this is hours of fun

00:02:11.039 --> 00:02:19.280
look there's a little bubble oh this is interesting

00:02:15.599 --> 00:02:21.280
it makes no meaningful thermal contact

00:02:19.280 --> 00:02:26.959
outside of it looks like this part of the spreader might go under there

00:02:24.000 --> 00:02:31.040
with the actual memory chips let's start i guess with the standard stuff then or

00:02:29.440 --> 00:02:36.800
no let's make sure this stuff even boots up first show me the post yes

00:02:34.959 --> 00:02:39.360
all right now that we're booted up let's go ahead and

00:02:38.160 --> 00:02:45.920
press start on a stress system memory test hopefully

00:02:43.200 --> 00:02:51.200
our fleer camera will tell us some interesting things about what's going on

00:02:48.480 --> 00:02:56.319
here we can see the heat is clearly concentrated directly over the actual

00:02:54.000 --> 00:03:02.080
dram modules the second thing that we can see is that my suspicion

00:02:59.200 --> 00:03:06.319
that there was some kind of contact between

00:03:03.599 --> 00:03:10.720
this medallion here and the water cooling at the top was

00:03:08.800 --> 00:03:14.480
probably not correct it looks like the only places

00:03:12.319 --> 00:03:19.120
where heat is being transferred up into the top chamber

00:03:16.239 --> 00:03:22.800
are kind of over here and i'm not sure why

00:03:20.640 --> 00:03:27.120
and then kind of over here so those are almost the same temperature

00:03:24.959 --> 00:03:29.680
as the spot directly over the chips so you can see if we look directly over top

00:03:28.720 --> 00:03:32.799
of it the water cooling portion is still quite

00:03:32.000 --> 00:03:38.959
cool okay so after a few minutes of testing our thermals have stabilized anywhere

00:03:36.400 --> 00:03:42.720
from around 47 to 50 degrees depending on where exactly we're looking on the

00:03:41.040 --> 00:03:47.440
spreader here but that's not that interesting we were expecting that what

00:03:44.640 --> 00:03:52.159
we did figure out that is interesting is why we're seeing those little

00:03:49.920 --> 00:03:56.080
centers of activity of thermal movement up here

00:03:53.440 --> 00:04:01.280
that actually came from perusing a data it's very optimistic by the way diagram

00:03:59.120 --> 00:04:03.920
of how these modules work so

00:04:02.159 --> 00:04:08.560
heat gets generated by these uh dram packages right here

00:04:07.120 --> 00:04:11.599
with you so far then it gets

00:04:10.319 --> 00:04:15.599
like i don't know it goes through these holes i'm not sure what they're talking about but there's there's a heat

00:04:14.000 --> 00:04:21.040
spreader here that then somehow theoretically heat up

00:04:18.320 --> 00:04:25.759
or something anyway the point is once the assembly is put together there's an

00:04:23.040 --> 00:04:30.240
actual heat spreader portion here and here that's causing those hot zones on

00:04:28.080 --> 00:04:35.919
these sides the reason this one doesn't work is because on a standard ddr4

00:04:32.960 --> 00:04:40.080
memory module there is no chip in the middle so there's

00:04:37.759 --> 00:04:43.520
no heat for this to carry away this is more efficient than this chunk of metal

00:04:42.160 --> 00:04:47.680
so we're going to go ahead and throw my regular test bench memory back in here

00:04:45.759 --> 00:04:51.440
and we'll compare against that so we still need a few more minutes with

00:04:49.520 --> 00:04:57.280
our other memory modules here but it looks like we're going to end up

00:04:52.880 --> 00:04:58.639
somewhere in the 40 to 40 something mid

00:04:57.280 --> 00:05:02.400
range so it took a little longer thanks to the

00:05:00.560 --> 00:05:08.320
additional thermal mass of these trident z modules but we are back up to

00:05:05.120 --> 00:05:09.440
anywhere between about 50 degrees and 47

00:05:08.320 --> 00:05:14.880
degrees just like last time so

00:05:12.560 --> 00:05:20.240
the rules of the game have not in fact changed RAM doesn't really need cooling

00:05:18.160 --> 00:05:25.440
unless you're you know extreme overclocking it to break records and

00:05:23.039 --> 00:05:30.880
heat spreaders don't really do a whole lot for it regardless of the design of

00:05:28.080 --> 00:05:35.360
them so what conclusion can we draw about this thing then i guess the best

00:05:33.280 --> 00:05:38.479
way i could describe it would be this

00:05:36.639 --> 00:05:41.600
the water on the top of these RAM modules

00:05:39.680 --> 00:05:45.280
it's not hurting anything it's like homeopathic pills where they just

00:05:44.000 --> 00:05:49.520
contain basically nothing

00:05:47.039 --> 00:05:56.720
but it's not helping anything and as much as we love our friends over

00:05:52.880 --> 00:05:58.720
at adata to say that it is water cooled

00:05:56.720 --> 00:06:03.759
is about like it would be for me to say that this CPU with a bubble of water on

00:06:00.960 --> 00:06:08.800
the middle of it is water cooled water does not inherently cool anything

00:06:07.120 --> 00:06:13.199
you have to have surface area that's why water cooling

00:06:10.960 --> 00:06:18.720
still needs radiators that's why heat sinks need fins and not just heat pipes

00:06:17.199 --> 00:06:24.000
well that whole thing was enlightening isn't learning fun

00:06:21.000 --> 00:06:25.520
brilliant.org sure thinks so brilliant

00:06:24.000 --> 00:06:30.560
is a problem-solving website that teaches you to think like a computer

00:06:27.759 --> 00:06:35.280
scientist by diving in and doing things for yourself rather than just trying to

00:06:32.880 --> 00:06:39.280
passively learn from lectures and videos they believe that a great education

00:06:37.360 --> 00:06:44.160
shows you how to solve new and unfamiliar problems by using critical

00:06:41.840 --> 00:06:49.039
reasoning skills with that said you do need a toolkit and a framework in order

00:06:46.639 --> 00:06:53.919
to work through things fortunately they also provide you with that so they'll

00:06:51.600 --> 00:06:58.080
take learning concepts break them up into bite-sized pieces present clear

00:06:56.319 --> 00:07:02.240
thinking in each part and then build back up to an interesting conclusion

00:07:00.240 --> 00:07:08.080
head over to brilliant.org forward slash Linus tech tips and try it you get 20

i mean to be very clear you guys it's not like it's bad memory you could still

00:07:27.840 --> 00:07:34.720
buy it if you're into just like RGB memory with a cool bar on the top
