this is the fastest gaming CPU on the planet right now installed in an 1100
rog motherboard but you know what it's just not fast enough for me we need
to go faster so today we're going to be taking Intel's core i9 12900k
putting a healthy little dollop of dielectric grease
all in these CPU pins there oh don't worry this is
for its own good and we are going to be taking it sub zero with our 3
000 watt CPU chiller that's right we're
hooking an air conditioner directly up to the CPU socket and it's going to be a
lot of fun ladies and gentlemen let's see how fast we can make this thing go
and who's sponsoring this mess see sonic wow that makes sense they'll sponsor
anything what 1300 watt powers apply oh
yeah i guess it kind of makes sense it makes a little sense you try and do stuff like this without a good quality
power supply you're gonna have a real bad time
go check out seasonic linked down below
you guys did your best on the installation job for part one here no we
didn't but i'm definitely glad that i'm here to supervise this time here's the
thing when i said that i was doing this for the CPU zone good that's the truth
the goop that i'm sticking into the pins in the CPU socket here is called
dielectric grease and it serves a very important function because while the
chiller project was an enormous success we managed to get this core i7 this is
an older one down to minus 20 degrees
celsius there are some inherent risks
that come with going that cold namely condensation so because you can't stick
you know a big old thing of foam into your CPU socket pins you want to use a
non-conductive grease like this dielectric grease that i'm smearing
around in here to make sure that we don't have any uh
moisture causing a short between the pins that would be a real bad time and
probably kill our CPU something to note guys is that as messy and awful as this
looks it's not harming the motherboard in any way and this board could continue
to function for years with this dielectric grease in the socket it's
it'll just be messy you'll be a messy boy give me give me more give me more
free brittany moore
it should be criminal to have this much fun at work it's hilarious
now normally at this stage we would install the CPU and use the hold down
and retention ARM to keep it in place but when you're going sub-zero you can't
afford to have any little air gaps around the CPU because that's where all
the cold refrigerant is going to be delivered and the thing is
something like this absolutely impossible to perfectly
insulate so you're going to get these little pockets where you get moisture condensing on the cold metal and then
dripping is it possible to both hate and love
something this much clearly
yeah because i'm doing it
your fingers are greasy it's probably fine
yeah it's pretty shielded oh yeah it's actually got a whole like plate on the
back and everything wow it's Linus proof
this is a disaster why did you guys do this is there another one
yep all right thank goodness yeah that one was already pretty shot the good
news is that we aren't going to do anything like that to it this time
because you don't really have to this is a cool feature of this board by the way it has not only the lga 1700 holes which
are standard but it also has the older style lga 1000 series holes so when
you've got an old cooler you can just put it on there you get it you just get
on there little buddy how much how much frost did you guys get on the back of
the board last time uh outside of that pad outside of that
pad yeah then the back plate's coming off i wish i hadn't put the dielectric
grease in just yet but hey that's what life is about learning
through my mistakes the good news is that none of this stuff that's got a
thermal pad on it on the back here is gonna need to be cooled
i should probably explain that pcbs or boards like this are made predominantly
of copper so copper happens to be an excellent conductor of heat which means
that if you cool this CPU socket area
it will actually cool a huge amount of the board around it
especially when the CPU isn't working real hard because there's just not
enough heat from these surrounding components to overcome the frost spread
now they apparently didn't find this when they were insulating last time
around but i actually have a motherboard
sized and with all the holes already punched through it piece of this
insulation foam here then i'm going to take the part for the CPU
i'm gonna put it right there and we're gonna stab all the way through and that
should pretty much do it for installation for the back of the board
so where are the uh where are the stabbies
uh over there okay
how many of them are three all of them oh they're all through yeah
oh nailed it um i think you might be mistaken though i think the
might be the outer one it doesn't matter though it doesn't make a difference to what we're doing
i mean we could just use the threads to kind of
oh no eliminate the gap between them this is a trippy kind of eraser that i
had actually never heard of in my life until i tried to subzero cool a machine
a few years back and learned that you like you like put
it down on the paper and then lift it up you don't like rub with it anyway it's
super malleable and it's a nice cheap way to
insulate around a CPU socket so this allows us to kind of push into you know
little gaps that we otherwise wouldn't be able to
to properly protect this is more for if you wanted to like daily drive sub-zero
cooling which by the way people used to do back in the day like there was a huge
small community um at like extreme
systems and stuff like that that would build you know custom phase change
coolers and and actually 24 7 their cpus
at subzero you always need to make sure that
you're focusing your your insulation on
places where you could potentially have moisture drip
so i'm going to make sure that i pack things in really good down around the bottom here
it's been so long since i've insulated a board feels good feels
nostalgic back when overclocking was fun you know maybe if i just will it to be
fun and have a point again it will we want to go right up to the RAM slots
because the last thing you want man i can't think of anything you want less
than moisture in your RAM slot uh metal chips i mean yeah metal chips okay i
mean it's not a competition alex now what we need is to get our
insulation up to the same level as the ihs of the CPU so the top of the metal
spreader we're going to use this for that
doesn't have to be the most crazy precise thing in the world
what's nice about sticking this stuff onto the artist eraser is that you can actually clean up the board reasonably
well when you're done you know it's another way to get no air
in there put it in a vacuum sealed container
no i refuse it's awful alex
i will not do that to this board not perfect not bad
now we need to un this defy this
now do you want this thermal probe in there yeah we need the thermal probe in there so we're gonna go right there
we're going to kind of force it into this crack
i want to get this probe cover just oh hold on hold on i lost the thermal loop
okay right there yep this is why i wanted it to be round by
the way i know i i know that it wasn't possible
okay so now we just have to get it down to the level of the
uh cold plate like you probably need a solid three layers of this stuff
over every part of it do you want to wrap that for me
oh yeah the adhesive on this isn't very good no it's really worn out this is
super old is there an orientation does it matter no okay
oh my god honestly this is like not that stupid
i'm serious it's really not so you'll want to do
another round of that and then don't bother trying to like poke holes or like
cut it perfectly just like put it on and just like poke it through the hardware
and then tighten down the hardware just like right on top of it just just make
sure you've got a pretty decent amount of pressure all right this is like going
to work now just more insulation
and hopefully we're good to go
now we want this tight but not
super duper tight but also pretty super duper tight
because it is holding in the CPU last time we had some issues with these
lines also getting all frozen and condensationy so with any luck
this will help prevent that oh
that's really on there freaking
heck yeah
should be so much better than last time
yeah yeah yeah
i mean that's pretty fine i think
uh where's our GPU at i like it i like it high enough performance that our
benchmark scores will still be like good and not bottlenecked but we're not
risking anything too expensive we've got a 30 60 going here
you know what's the craziest thing about this chiller
is that it is conceivable that we could actually hook a GPU up to it as well in
the future just with like a splitter or something like that off here yeah it
won't go a whole lot colder like you'll be able to see the
condenser temps right here but it can definitely pull a lot more
heat out of stuff yeah it'll be really nice to have just like a ready-to-go
sub-zero cooling solution just
like that uh oh our RAM is gone oh yeah that's
pretty important i don't want to lose that ddr5 RAM this stuff's expensive as
fragi isn't it uh yes oh yeah this is the 6000 cl 36 stuff
um this stuff better not die
i mean that's okay g skill you would you'd forgive us right g skill watching
like i'm so damn excited right now are you
ready uh sure should we make sure this turns
on first oh yeah right if okay if we were daily driving the thing normally
people set up a relay so that when you press the power button on your computer
it also fires up your compressor and your fan for the condenser but no we don't
have that so yeah go ahead never do this
this this is mains power never this yeah none
of this none of this the only reason we have it still
connected at all is because you can't just
plug in a modern compressor and condenser and expect it to just run full
tilt all the time and you wouldn't even necessarily want it to that wouldn't be healthy for it so this is the controller
that has all the safeties like say for example the safety that turns it off if
the evaporator fan turns off which is why we have this sitting here spinning
oh i'm gonna let go of that all right let's turn this on fire it up
come on okay we'll see if it starts we might need to warm this thermal probe up
a bit
oh huh there we go there we go the fan spinning i really
hope it posts especially after i lectured you guys
about your way of insulating if my way doesn't work better then i'm
gonna look like a jackass oh it's officially sub-zero nice come on
baby i see flashing on the floor there we go yes
okay that's step one step two is ignore fan monitoring oh
yeah these are already frosting
definitely need to cover these up you see what i'm doing here brandon i'm
just covering up that exposed metal from the the bolt through brandon there's a
little display on this ridiculously fancy motherboard if you come over to
where i am you can see it's gonna pop up CPU package zero degrees
there it is it could very well be lower but that might be the limit of what it'll display
yeah the radiator inlet's currently at 16 and a half degrees which is ambient
so we are not able to get any colder than it's 14 right now negative 14 minus
14. okay well i mean hey that's not a bad start
yeah it's not warm yeah do we have any parts of it that are
sort of scary cold and we're worried about condensation on
uh
some of these bits around the top are very cold
like right here yeah okay uh the good news is at least to the
touch it feels not bad
what you would normally do assuming you actually wanted to 24 7 this thing is
you would keep the computer off during this kind of testing like where you're
you know looking at temperatures and checking for condensation because that
way any moisture is not going to harm it then what you would do is you would make
sure you'd run it for like 24 hours take it all apart kind of go okay did we
actually get any moisture pockets anywhere and then if you didn't
then it's safe to fire up your phase change cooler and go to town because if
it doesn't if it doesn't get condensation on it when there's no load
on the CPU it definitely won't when the CPU is generating some heat
and it looks like that worked so we are uh
we're turboing which i guess we expected
CPU is like oh yeah i think i got some thermal headroom yeah i feel like if we
just use ASUS's ai overclocking crap in the
BIOS we can probably get it going pretty fast
real quick uh
i sincerely doubt that it's related to the chiller right now it's probably just
this RAM being bleeding edge uh have we
updated the BIOS of this board uh no we haven't we should probably make
sure we've got whatever the latest retail BIOS is as well brand new
platforms man you just stuff happens
that's why whenever you've seen us update our editing workstations for example i've seen criticism from people
like oh you guys aren't even using the fastest seven like no dog
we go with something proven when we need to actually get work done gaming machine
sure whatever you get a blue screen once a month who cares but like
no no not when you're working task manager just in case we need that for
whatever reason okay we are
apparently at zero degrees should we try putting a little load on it just to see
what happens sure make sure that it doesn't freak out
our score to beat is 27 000. oh my god
our CPU is running at 30 degrees on the
package running cinebench
i think we've got a little bit of headroom yeah i think it's working
so score 26 866. did we thermal velocity boost more than
we did before no okay so it's basically the same yeah
okay well then it's time to uh time to turn
up the juice you just cranked it all the way to the right yeah which you can do
whatever you want it's probably do like a half a volt offset that probably makes
sense what is that even based on you're just dragging sliders around yeah so
okay what we're looking for is like 1.42
1.43 volts that'll get you like
pretty fast on these okay
so then we want about 0.25 then
yeah that probably makes more sense
we'll not be able to recover to a valid state automatically
hold on oh brandon didn't see that yeah that was an amazing error message sorry
you missed it it basically said your system will not be able to recover to a
valid state automatically if this thing crashes
it's going to crash let's see what happens if we actually put a load on it
60 degrees now 80.
i think we have a thermal bottleneck alex
i think our we're also drawing 420 watts our interface is not good enough nice
boost though 28 605 well it's faster let's run it again and
let's have a look at our CPU frequencies
5.2 on all performance cores and 4.0 on
all efficiency cores why is it supposedly reaching 100
degrees and thermal throttling
but keeping that frequency the whole time yeah it's kind of weird
i would expect it to drop if it was actually that hot i wonder if it's not
actually reading it properly how high are these efficiency cores
supposed to go i haven't actually looked into this at all the highest that i've
seen people get them is like 4.1 4.2 but they'll do four pretty easily
well let's go for 4.2 all right i mean how many times do you live right
for this board maybe once there they go
doing it okay so the core temperatures are saying that it's at 60 this time despite it
running faster i think it was just bugged before
29.097 that's really fast that's really fast
we are dangerously close to 32 core threadripper 2990 wx territory we have
half as many cores guys half as many cars boys
okay well the only responsible thing to do at this point is to take our two active
cores and see if we can do like 5.5 you know what let's just try
plus 0.3 volts and see what happens ah
uh yeah i don't think our CPU is happy
i'm a little bit suspicious that our problem is current and it's going to
cause our voltage to drop when we hit all the cores at the 5.4
and that's why it's shutting down we also might just be at where the silicon
like its absolute limits but i feel like we can push it a little
bit faster now i have the multimeter hooked up
to the pins here so we can see the core voltage on our multimeter
and i feel like when i hit go it's going to go up to like 1.4 and then it's going
to drop and then the system's going to crash but let's see
the core temperatures are going fine so it must have just been a problem with
the reporting before once it was over 100 degrees
we drew 264 amps during that run often
i think we need to leave xtu for a little bit
and go into some real hardcore settings here
by hardcore settings i mean just disabling all current limits we'll just
come in here oh don't crash oh damn it
you crashed oh you piece of we bring out the camera and this is what you do
well we beat the threadripper um i guess it's not quite stable
i guess at the last two cores we tried to get to 5.4 gigahertz they're not very
happy there uh 5.3 seems to be where they want to be the rest can do 5'4
but this is basically what we're doing so for every CPU you have your voltage
and frequency curve 4.5 gigahertz you come over here it's like
1.15 whatever volts is what you're getting so first thing that we have to
do is extend this so it goes to like 5.2 right now we want to
go just kind of up here and then we just offset the
whole thing by a point zero
five volts or something like that raise the whole thing up so hopefully it's
more stable hopefully we don't get as much droop although it's an insane
amount of voltage this thing is taking right now it's like
over 400 watts it's pretty stupid but it seems to be working i would very
strongly recommend scatterbenches alder like overclocking guide it's like an
hour and a half long but the amount of information in there is obscene if you
want to actually overclock these things go and watch that but anyway
all of the cores are at 5.4 gigahertz
except for the last two there are 5.3 they don't seem happy at 5.4
all of the efficiency cores are still at 4.2 gigahertz
and we're running what only 1.3 volts
although it does get higher than that as you're going to be able to tell from
here so it's saying we're drawing 371 watts oh
no
oh why did we turn on the camera brandon
it was working before
that's how it always works thirty thousand fifty four to beat also
not crashing to beat
oh 3064.
heck yeah beat it by 10 points
that's pretty crazy given that we have literally half as many cores as the 2990
wx i'm getting slightly concerned i can see that where the thumb screws are
there's a little bit of condensation if you look like over here
the amount of frost is obscene this thing is so freaking cold that gives you
an idea of what it's like inside that CPU and why
if we didn't have all insulation be having a real bad time
now let's come over here i upped the voltage just a tiny bit
it's probably going to crash we've the second that we brought the camera is
just been crash city because of course it is
yep piece of crap did we get there
we did we beat it by 700 points and then stupid brandon had to turn his camera on
we can't do it again yes this is your fault brandon we didn't
get it once on camera we only beat it by 10 points i think it meant stupid
situation brandon had to turn his stupid camera on it's not the brandon that's
stupid it's everything else oh my god we did beat it like look it's
within 55 points on this run you know what
i'm calling that a victory i'm calling that a victory it's obvious there's
still work that we could do whether it's on our evaporator design whether it's on
the flatness whether it's on our mounting pressure or whatever the case
may be but i think also with just like it's a
pretty cool setup we're in real like tweaking the little list of
voltages and frequencies and stuff like we're right on the edge in terms of if
you've got an outstanding cooler what to expect from alder lake
this is about it yeah just like you'd always expect me to
tell you about our sponsor what is there to say other than sea sonic they make
great power supplies that that's right can deliver
watts nice over the 8-pin CPU power connectors
and do it nice and stably so that you're not going to be giving up any potential
overclocking headroom because you got a crummy power supply so go check them out
they've got up to 12-year warranties like what
and we've got them linked down below okay let's shut it down and have a look
at the yeah the nonsense whoa okay well there's
definitely some frost yeah i was a bit concerned about those i think everything
else might be fine
so this all there's a little bit of moisture right
in here right around the CPU the rest seems dry
this also is all dry that worked fantastic
back of the motherboard oh yeah that's totally dry bone dry back
there this worked really well well i'm super stoked that we were able
to get this processor faster than 2990 wx that's
frigging insane huge thanks to see sonic for sponsoring
