feels like every time i come in this room it's some crazy cooling experiment
usually with you the air con is good in here
which is
and that actually probably makes sense because this room isn't big enough for
us to actually hold meetings in here anymore and because we're at it yet again this right
here is a bizarre cooling product this is the
ic graphite thermal pad
the last thermal interface you will ever need
they claim that this thermal pad
performs as well as thermal paste
it is extremely durable so it could last for decades
and it's reusable
let's investigate shall we
after i tell you about private internet access pia is the vpn service that
encrypts all of your internet traffic and uses a safe protected ip and it's
got lots of other useful features as well you can check it out at the link
below
ow
well it conducts heat yeah really well especially in the x y
all right so what the hell is this thing
so that's totally graphite um which i guess is carbon
i don't know exactly what to say for the what exactly is this i have notes um
this is the innovation cooling graphite thermal pad
the goal of it is to replace traditional thermal pastes in long-term applications
its main advantages are its easy application there's no guessing how much
to put on it's extremely long life and
it's high resistance to thermal changes which make it also good for extreme
cooling scenarios where liquid metal or normal thermal paste might freeze
so in a nutshell what they're saying is that this pad
even though it will be so thick compared to a paste has no real disadvantage
compared to spreading goop on your CPU
well one disadvantage is that it
is electrically conductive so
one yeah like two ohms
which is like better than a wire but if you just toss it on your motherboard
it's going to fry it so
okay so you do have to be more careful but unlike liquid metal it's not going
to seep out yeah it's not going to just go everywhere you can
get it pretty on there so would you just cut it to size if you had something that
was yeah so the main spec on this is its thermal conductivity 35 watts per meter
kelvin but i think probably most people wouldn't have a ton of context for what
that means so compared to like ic diamond that's
really high so this is like four and a half watts per meter kelvin so it should
be able to conduct a lot of heat through it
but what is a watt per meter kelvin
you don't know exactly do you no why do i even employ these people i'm looking
it up right now unfortunately there are differing definitions for these terms
okay so quantity of heat that passes in a unit time through a plate of
particular area or thickness when opposite faces different
temperature by one kelvin
so that means that if there's one kelvin difference between the two
you can conduct 35 watts per meter so it
actually makes a lot of sense when you think about it like that cool let's try it
this is trippy man like
cleaning all of the paste off
and having it just like dry mounted
like there are things in life that feel natural to mount dry
and there are things and there are things that don't
uh so an advantage to this dry approach
is that there's no liquid
like you know most thermal compounds are some kind of a suspension of some sort
so there's no liquid to eventually evaporate or dry out or mush out or
anything like that it's just that's just it you just plunk it on there this is
crazy just for the sake of you know transparency
no thermal paste double screw on the driver oh you
finished first now i feel awkward
okay it's trippy like it seems like it it's
not right you know so we're looking at this is a 7980xe
with liquid metal in it okay so we're looking at an average
temperature across all cores of 50.56
and that was with ic diamond yeah so i see diamond might not be the highest
performance thermal compound but it's very respectable they're all within what
like two degrees of each other at the high end yeah i mean we had that bulk stuff that
didn't perform particularly well that video is worth watching you can check
that out here well nothing's immediately concerning nope that looks very
impressive yeah what did we get on icy diamond
max 58 average 50.56
like it should perform in everything that i've read
one to two degrees worse but
i mean that's part of the argument for a solution like this
that there's no room for user error
yeah like i might have done a bad core application or a bad mount so at the end
of the day that's the conclusion of this video alex is a bad man
we won't know for another uh 20 minutes or so
or maybe five minutes i don't know
all right so it's been
hours yeah yeah okay cool how do we do
plus 50 plus what's the point of even having a fancy
ass calculator if it doesn't get it right well it's not the calculator's fault
so it's the user heatsink's barely warm which i guess
makes sense it still trips me out so this one from
alex's pre-testing has actually been used a couple times
and innovation cooling told us that they've had people beta testing these
that have reused them like over 20 times
over 50 even over 50 yeah over 50. all
right so our average is 51.7
so exactly what we expected okay so all
that's left for me then is
i want to i want to see like is it thinner yeah like i don't know like
let's shut it down all right oh one thing that is cool about it is
that it has um the 35 watts per meter
kelvin that's in the z direction so like up and down
but it's 800 ish 800 000 they're not totally sure
what's per meter calvin from side to side oh so that's why it burned me when
i torched it yeah so that's really good if you have like a hot spot on your CPU
it'll get it out to the heat pipes really well
one thing i don't like about it that much is the size
why well
i mean that looks fine for a core i9 but if i was cooling something like a
threadripper or one of Intel xeon scalables or something like that like a
really big chip i
kind of feel like you could actually have die area
can you just use potentially not covered i i don't know it's a wonderful question
i don't know the answer to that so it should be like that in
theoretically nothing would ever happen to it at all yeah they said lifetime
it should be about the same i think the coolest thing about this for
me is like you know for the last 10 20 years you know every other month there's
like a big article about how you know
carbon nanotubes or this other novel implementation of carbon is going to
completely revolutionize everything and up until now at least in the thermal
space although theoretically it has great thermal properties we haven't
really seen anything and now here it is you can buy it you
can stick it in your computer yeah completely commercial
and it works

community for ooh i'm sorry and our community forum which you should totally
join so like theoretically there's no reason
for us to ever apply thermal goop again we just throw
these on everything from now on and just reuse them forever like i guess we could
yeah take that thermal paste
no no it's like
you've got so much of it though
