frankly i'm not even 100 sure where to start with this one meet
a data's spectrex d80 ddr4 memory as
they're calling it the world's first RGB ddr4 memory with
hybrid liquid air cooling system
using a combination of a liquid heatsink and an aluminum heatsink to deliver
effective thermal cooling water cooled memory
welcome my friends to [ __ ] manufacturers
say this
this is water-cooled memory
throughout this video Linus will refer to the liquid as water this is
inaccurate the liquid is in fact 3m novak however Linus is having some
well-deserved time off making a vocal correction impossible so here i am rock
you like a hurricane here i

description well we're off to a good start the shutdown button doesn't work
brilliant who needs to shut down their computer anyway
what am i supposed to do
now i could just chart all over this stuff based on
pure principles of cooling theory because i
actually don't need to plug them in in order to know that the water cooling on
them is really not doing anything but i
at least try to take manufacturers claims somewhat seriously i want to give
them every opportunity to prove me wrong
here so what i'm going to do is devise an experiment one thing's for sure they
look pretty cool other than that they have a red heat spreader on an RGB RAM module on a more
positive note this is hours of fun
look there's a little bubble oh this is interesting
it makes no meaningful thermal contact
outside of it looks like this part of the spreader might go under there
with the actual memory chips let's start i guess with the standard stuff then or
no let's make sure this stuff even boots up first show me the post yes
all right now that we're booted up let's go ahead and
press start on a stress system memory test hopefully
our fleer camera will tell us some interesting things about what's going on
here we can see the heat is clearly concentrated directly over the actual
dram modules the second thing that we can see is that my suspicion
that there was some kind of contact between
this medallion here and the water cooling at the top was
probably not correct it looks like the only places
where heat is being transferred up into the top chamber
are kind of over here and i'm not sure why
and then kind of over here so those are almost the same temperature
as the spot directly over the chips so you can see if we look directly over top
of it the water cooling portion is still quite
cool okay so after a few minutes of testing our thermals have stabilized anywhere
from around 47 to 50 degrees depending on where exactly we're looking on the
spreader here but that's not that interesting we were expecting that what
we did figure out that is interesting is why we're seeing those little
centers of activity of thermal movement up here
that actually came from perusing a data it's very optimistic by the way diagram
of how these modules work so
heat gets generated by these uh dram packages right here
with you so far then it gets
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
spreader here that then somehow theoretically heat up
or something anyway the point is once the assembly is put together there's an
actual heat spreader portion here and here that's causing those hot zones on
these sides the reason this one doesn't work is because on a standard ddr4
memory module there is no chip in the middle so there's
no heat for this to carry away this is more efficient than this chunk of metal
so we're going to go ahead and throw my regular test bench memory back in here
and we'll compare against that so we still need a few more minutes with
our other memory modules here but it looks like we're going to end up
somewhere in the 40 to 40 something mid
range so it took a little longer thanks to the
additional thermal mass of these trident z modules but we are back up to
anywhere between about 50 degrees and 47
degrees just like last time so
the rules of the game have not in fact changed RAM doesn't really need cooling
unless you're you know extreme overclocking it to break records and
heat spreaders don't really do a whole lot for it regardless of the design of
them so what conclusion can we draw about this thing then i guess the best
way i could describe it would be this
the water on the top of these RAM modules
it's not hurting anything it's like homeopathic pills where they just
contain basically nothing
but it's not helping anything and as much as we love our friends over
at adata to say that it is water cooled
is about like it would be for me to say that this CPU with a bubble of water on
the middle of it is water cooled water does not inherently cool anything
you have to have surface area that's why water cooling
still needs radiators that's why heat sinks need fins and not just heat pipes
well that whole thing was enlightening isn't learning fun
brilliant.org sure thinks so brilliant
is a problem-solving website that teaches you to think like a computer
scientist by diving in and doing things for yourself rather than just trying to
passively learn from lectures and videos they believe that a great education
shows you how to solve new and unfamiliar problems by using critical
reasoning skills with that said you do need a toolkit and a framework in order
to work through things fortunately they also provide you with that so they'll
take learning concepts break them up into bite-sized pieces present clear
thinking in each part and then build back up to an interesting conclusion

disliked this video then um
you know i'm sorry to hear that it's a sad time for all of us but if you
liked it hit like get subscribed and maybe consider checking out where to buy
the stuff we featured at the link in the video description
i mean to be very clear you guys it's not like it's bad memory you could still
buy it if you're into just like RGB memory with a cool bar on the top
