Happy birthday, V. Here's my present.
Previously on LT, I showed you guys this incredible $30,000 CPU cooler that is
designed for one reason and one reason only, to chase PC performance records.
But while you guys might have expected me to turn a CPU blue, instead it was
your balls >> because I teased it, but never actually
hooked it up to any hardware. Well, that changes today. And our goal is simple.
Break a world record. And overclocking
legend Charles Fuggerworth here gave me his personal guarantee that we will do
it. So, uh, what are we waiting for? Well, we got to prep the motherboard. We
got to insulate the socket. We got to update the BIOS. We got to upgrade the
VGA BIOS. We got to install the Windows. We got to tune the Windows. And we got
to prep the uh VGA driver. >> And uh, we got to get some power cords.
Oh. Oh. Oh, no. We got those. We got the power cords. Um, we've got seven
circuits to work with. >> Just seven? >> Wait, is that not enough?
>> I think seven will work. >> Okay. As for the rest of it, well, um,
it's a good thing we've got the whole day booked for this. And we've got the next 20 seconds booked for our sponsor,
Delete Me. They can take back your private information from the hands of
bad acting data brokers who might be selling it to the highest bidder online.

Before
we can begin, one of the key enemies of sub-zero overclocking is condensation.
See, the air around us is full of moisture, and it will gather on any cold
surface, turn to liquid, and drip all over your sensitive electronics. Now,
there are a number of different ways of approaching this problem. The board I'm
holding in my hand uses a very similar approach to what you guys saw recently
when we were chasing world records with our RTX 5090 Astral. You basically take
Plasti Dip, suck it up into a syringe, and drip it all over the sensitive
components, being sure to keep it away from any contact pins, say in PCI
Express sockets or in your power plugs. Next, you find a high quality neoprene
like closed cell foam, cut it up into nice little shapes, and fill in any big
gaps. Of course, that's a ton of work. Makes your board super ugly. And in the
event that anything goes wrong, Asus certainly isn't taking this back for an
RMA. So, Charles has a technique that he likes better, and it's to use nothing.
>> Absolutely not. I just use a kingpin socket heater.
>> Oh, so that goes on the back here. >> Yeah, it goes on the back of the board.
It's a couple hundred watts heating element. >> So, counterintuitively, you're heating
the CPU area. >> Correct. Correct. Correct. It it prevents uh moisture from uh building up
on the back side of the board. >> Okay. And then what about the front? >> Um I use a little bit of uh insulation.
Oh, >> just neoprene. >> Just kind of like this. >> Yeah, just a little bit of neoprene. No
>> glue or anything. >> No, no, no heat. And then I use a WD40.
Uh WD40 specialist. >> Shut up. >> No, >> you put WD40 in your CPU socket.
>> I spray it directly in the socket and I I fill the socket and I can actually
fire the system up with the socket wet. >> Now, you told me that you thought a
manufacturer like wouldn't be able to tell you'd put that in there. Is that
true? >> Correct. It's undetectable. Completely undetectable. Um,
>> that's a tech tip. Little bit of RMA fraud tips. We're not actually
advocating for that. >> Oh, you need your board clean.
>> We're actually going to be using the first board today, though. And it looks great. Like, we could probably run
Subzero for hours, days at a time on
this. But there is one small problem. Um, Noctua probably doesn't make a
secuer mounting bracket for your Cascade chiller. So, how do we get the thing on
the thing? >> I make my own custom 3D printed brackets. Um, these are for different
sockets. Um, that's for X299. >> Oh, cool. Okay.
>> And this is for AMD, AM5, AM4. >> Oh, cool. Hey, got the Extreme Systems
logo on there. >> Yeah. >> Now, it looks like you're using Oh,
crap. >> Nylon. >> It's the Oh, >> that's the HP Multijet Fusion.
>> Wow. It feel You can't break it. >> Feels great.
>> It's the HP Multijet Fusion 4200. Like I I don't think I could break this.
>> No. >> Just in case I ever have to swap it. Can you show me how to do it? You said you
wanted a screw. >> Yeah. Yeah. >> So, just just pull it back a little bit.
Expose the O-ring. >> Uhhuh. >> Pull the O-ring. >> And I just give it the old Ow. I stabbed
myself. Well, we're off to a good start today. Okay, there we go. Okay, O-ring's
off. And that's that. Zip tie engineering.
Now, have you ever shown anyone what's inside this evap head?
>> Uh, 20 years ago. >> Super cool. And can you can you kind of
describe it for us? Like is it a maze style or like like what are >> this is this is a spiral evapor. This is
this is the prototype spiral evaporator. This is the first one I ever made. >> What's better about the newer ones?
>> The newer ones are a thinner material. Um so better the faster heat transfer.
>> Now if I wanted to swap it out for AMD then do you want to show us what that
would look like? >> This is a mounting plate. >> Yeah.
>> Goes into the adapter. >> Just goes right on.
>> Goes on like that. >> Install the O-ring. Oh, that's actually
shockingly elegant. Now, are these O-rings on one time use? Did you just
>> No, no, no. They're they're multi-time use, but I got a lot of them. >> Oh, I see. Okay. You were just worried I
was going to ruin it. >> Yes, I was being honest. I've watched your videos.
>> Why is it Why does he have the sickest burns >> for the coldest machine?
>> Yeah. Now, is there a reason that we're going Intel today? Specifically, the
285K. >> The 285K um is great for the benchmark
that we're going to run. An NPU boost is extremely strong in the benchmark.
>> Last question for you. Did you choose nylon for its ruggedness or for its
insulating properties or both? >> Both. I went with a PLA at first and the
PLA broke right off the bat. >> Before I put this on, maybe dumb question, but how flexible is this?
>> Um, okay. The hose itself, this part is
flexible. That part is not. >> Okay. So, is everything I'm doing okay?
Okay. Yep.
Okay. Oh, great. We don't even have any thermal compound. But here's the thing,
you can't use just any thermal compound. What would you go with?
>> Probably some thermal grizzly cryionut. >> And the reason for that is that certain
thermal compounds might perform great at
ambient temperature or hot, like uh liquid metal, for instance, highly
thermally conductive. But here's the thing. We're not going to be at room
temperature. We're going to be way below. And that liquid metal would become solid metal.
Not too great. >> Also, liquid metal is a bit messy. You're not into the mess.
>> No, not at all, actually. >> Yeah. I guess you do this for enough years, you just you become not into the
mess. And it just goes on like this. >> Okay, hold on one more second here. We got one more piece. I got a new piece
got new piece of neoprene here. >> Right. For around the bottom here.
>> Correct. Correct. I need to cut it. So, it needs to clear the memory slots cuz
these are dual channel or dual dim board. >> Oh, sure. And then that just goes on
there a little something like that. >> Once you get to there, then we'll bring it down another about a centimeter.
>> About a centimeter. Okay. Now, it's funny. You were making fun of me the
other day for using a rando mixture of imperial metric units, but I just heard
you use a centimeter. >> Well, it was less than an inch, so I had to use something else.
>> You're measuring things like a Canadian now, boys. >> Well, I'm in Canada.
>> And what's special about this particular Viper kit? >> That's the new ultra set from uh
Patriot. That's the uh 6000 C28. >> So, just super tight latencies and and
good rated speed. >> Correct. With CPUs, you know, you guys
would take the time and you would hand bin. But in the case of memory, do you
basically trust that the top kits from someone like a Patriot are already
binned enough or do you bend those further? >> We bend them further.
>> Okay. So, this is a particularly nice kit of this. >> Correct. Super bend. God bend.
>> The last thing we're going to need before we can fire up our bench is a GPU. Now, we're not going to need RTX
5090 performance for the first record we're chasing because it's solely
concerned with CPU benchmarks, but it's here already anyway. It's sub-zero
prepped with plasti dip all over it, not to mention paper towel, and it's hooked
up to Bruce Chillis, our industrial
chiller, which we don't have to run at sub-zero speed, so we're probably just
going to run it at, you know, 10 20 C for starters. Let's get this on here.
Now that the bench is together, it's time to fire up the chiller. But there's
a specific launch sequence starting with the first phase. If you haven't seen
part one, this is a cascade system that essentially uses a refrigeration system
to cool a refrigeration system to cool a
third refrigeration system in order to reach ungodly low temperatures. We're
expecting 90 Celsius on our CPU. Rock
freaking solid. But we can't just turn
on the compressors willy-nilly. We've got to turn on the first phase first,
which is the bottom one. Correct. Neat.
Because Charles actually legitimately doesn't know how much power it draws.
This will be fun for both of us. We got a few kilowatts and we're going to hook
them all up in line with Here we go.
Power. Ah, it's alive.
>> Well, what do we got? What do we got? >> Oh, 116.7 volts. One sec. 941 941 watt
>> just a few. >> So, you can see why Intel's recent woes
around power consumption of their chips doesn't bother him. His cooler a third
of it >> draws 1,000 W. Now that the first two
phases are kind of settled in, they're at 700 750 W each. But we haven't even
added the third phase yet. >> I can't read it. What does it say?
>> It said 250. Oh, that's not bad. >> And then it jumped to 1100.
>> That's That's a lot more more. And now we're settling in around the same. Now
we know how much power it consumes. Now let's see how much power it can make. Oh
wow, we're already at 13 below 17 20. I
guess we can turn on the computer. Hey, Charles actually brought up an overclocking buddy of his. They're a
member of the same team. This is Max at is actually his memory that we're
borrowing. >> Yeah. And board. >> So do you want to tell us what you're changing? >> We're going to change the performance
preferences from the Intel default settings to the ASUS advanced OC
profile. Little multi-core enhancement. We are going to enable and remove all
the limits. We're going to set manual for our AI overclock tuner.
>> NPU boost level three DRM timing control. The Apex has a lot of nice
useful profiles. You have 9 Gear 4 for
the 24 gig sticks. >> Oh, cool. >> 9,000 for the 16 gig sticks and the 24
gig sticks. So, we're going to run 9,000 on the 24 gig sticks and just leave it.
>> You don't even have to like tune any of the sub timings or any of that crap.
They just did all the work for us. >> Yep. Make it really easy. Now, is that something that you would find on
anything other than like, you know, an Apex, like a top tier board?
>> Um, I think the lower end boards do have some features. >> The Stricks does have that. The Stricks
has that as well. Very. >> They aren't as aggressive. I I don't think you're going to be running 9,000
on a, you know, Ford D. >> Cash is uh 49.
>> 49. Seems high, but >> you want to go 48? That's fine.
>> All right. We'll go 48 for the start. We'll take it at 48.
>> Hacking the main frame. >> So, the D2D ratio is the interconnect.
Uh, Aerake is a chiplet design. So you
have your SOC on here, your memory controller is I think on there too.
>> And if we cared about onboard GPU performance, for instance, maybe we'd
care about that or >> Yeah, it increases performance across the board. Uh memory memory bandwidth at
really high speeds with like no NPU boost on this,
>> right? The IMC is on a separate chiplet, isn't it?
>> Latency is a kind of an issue. >> Intel, it's okay. You'll get them next
time, boys. >> It's a very strange design. It's a effectively a monolithic CPU that is
chiplet on a single die. So, we're going to change our Vcore to 1.35 volts.
That's all we need. Huh. >> You tend to not need as much voltage as you would uh the colder you go, but it
really is dependent on the chips. There's a leakage factor, which is how much power these chips draw. And
typically, a higher leakage chip will require less voltage and will scale
better with temperature. >> Ironically, the leaky chips are not
necessarily the ones that Intel wants for the chips that going to ship to
consumers. Uh they tend to not be as efficient when you're operating them
normally. And then we're going to change it to from regulation mode, which is using the
uh DLVR on the CPU. >> So the VRM will output a higher voltage
to the CPU and the CPU steps it down. We're going to bypass that with power
gate mode. >> Got it. So we're just going to let our board do the work because we know that
we have an outstanding board that's going to deliver nice stable power. >> Yep.
>> Something we'd never recommend that you actually do for real world performance,
but if you're just trying to chase the highest possible number, >> it is very fun. Once we're done running
PC Mark 7, it'll have the the screen up with the with the result.
>> We're going to open up four copies of the CPU ID. Yep. >> We're going to set up four boxes. We're
going to set up the CPU, the motherboard, the memory tabs.
>> Okay. >> And then we're going to do a screenshot. And then we're going to have a world
record for you. >> That That easy. >> That easy.
>> You got to be kidding me. >> Well, we got to save the result. >> I
All right, here we go. PC Mark 7. Let's go, boys. Wait, before we actually do
the run, I mean, can can we can we just put it under load and and see how stable
the temperatures are? >> Okay, sure. >> Okay. W prime. >> Yep.
>> Okay. >> Are we at 64.4? >> Yeah. Okay. >> It's a very popular older benchmark.
>> Wait, >> we got >> Did that run? >> Yeah.
>> It didn't even move. >> That is crazy. It's gone up a degree and
a half. >> And so my expansion valve will kick in and it'll compensate for the load
balance out now. >> That is so cool. And we're going the
other way now in temperature. Look at this. >> That's the wrong way.
>> He's right. We're going back. We're going back down. We went from negative
104. 4 to like.5.6
back to 0.5. Still >> it'll fluctuate a little bit. >> We're within like
three.5. Yeah. But with the EC cores on and
running around uh 5.8 or 5.7, we might
have like a 2°ree fluctuation. And that's with a 285K with the Raptor Lake.
We might have like a four degree, >> right? She's on the Intel team, but you
know, if we're being honest, she was a hungry boy.
>> So, we're just finishing up and we're at our coldest temperature yet. >> So, we're pretty damn stable if we're
able to run like a stability test right now. >> Yeah. So, this is a thermal expansion
valve right here. And this thermal expansion valve responds under load.
>> So, now it'll go back down in temperature again as we're we have no load,
>> right? Okay. But then it'll go, "Oh, hold on a second. We're good. I don't
need all of this extra coolant and it'll back it off.
>> Yeah, >> because there's nothing you can do about the temperature of the refrigerant,
right? It's within reason, right? You're not going
to run your compressors at like a variable load. This is not a
sophisticated, you know, modern heat pump or air conditioning system. These
are these are running at a at a fixed speed. So, what you would do then to
achieve this kind of temperature control is you're adjusting the flow rate
through the evaporator head. So, it's the that my understanding is the
temperature of the refrigerant should be basically the sameish.
>> Correct. >> But we just juice it way more when we
need more cooling. >> Right. It opens up the valve more.
>> Cool. Are we ready to do the run or did you guys need to go double check
something? >> No. No. We're all good to go. We just got to press the go button. >> Yeah. You can uh really see how much he
runs benchmarks. >> That is that the current world? >> Yep, that is.
>> Do you ever run actual video games? >> Yeah. Oh, okay. I mean, some people get
they get so into the benchmarking they don't actually game. What's your game
right now? >> Well, I just finished up Battlefield 4 as Riker Recker. Sorry.
>> He's still working his way through his backlog. >> Yeah. >> Okay. >> Okay. So, we're going to go click the go
button. >> All right. I click go. I mean, we're all on the same page that just because I
click go doesn't mean I set the record. Like this is >> No, no, no. You click go, you set the
world record. >> Yeah. I really don't think that's how it works. >> That's how it works. >> I really I set the rules. That's how it
works. >> How long does this take to run? So this is 15 20 minutes. But actually what's
hard about this for the L&2 guys is the duration of this benchmark and pouring
and keeping this thing under a consistent load. As to where the Cascade
can keep this under a very consistent load for a very long duration in case
you have to rerun it and rerun it again and rerun it again.
>> Um the Cascade you can just rerun this thing all day long and have it, you know, consistent runs every single time.
So it's going to be extremely hard to catch your score. >> Right. Got it.
>> It's going to be extremely hard. >> My score. You're going to be on the world record rankings for a long time
>> and let the other guys chase you down. Good luck.
>> We didn't get it on the first run. >> That's his fault. >> Can you stop assigning blame to everyone
around here? >> Hey, he told me what settings to put in. >> He did do that. >> But you had the RAM set up, though.
>> That's weird. That's not memory. >> That could be that could be memory.
>> That is CPU. I know for that CPU. We'll need a minute.
>> Now, you guys tuned one more thing. This is our third run. What did you guys
change? Uh, the NPU boost. I dropped it down. >> But we're still at 9,000 mega transfers
on the memory. >> I think about there. It's got to be 15,7.
>> So, it'll take two runs. >> So close.
We're so close. >> We got this.
>> Okay, we got this. We got this. >> Graphics 315. We just need to bring up
our GPU just a little bit. >> Oh, yeah. We could do that. >> Just bring up our GPU a little bit and
we're we're there. >> And now we play the waiting game. Here
we are. Our run number two. Well, three, but who's counting?
>> Oh. >> Oh, no. >> Oh, this data file corruption. >> Yeah.
>> Seriously, we made it this far and then it's upset that it doesn't know the CPU
name. Third times a charm. >> This is a third run, right? Sure. I
mean, it's movie magic. It can be whatever run you want it to be. >> If you edit it, it could be the first.
>> All right. >> Oh, we went down. >> How do we go down?
>> Our frames per second to go up. You didn't put any GPU clock on it, man. Oh,
cuz I reboot I rebooted. >> One moment, please.
Time to get the results from our second attempt.
>> Movie magic, right? >> The same error again.
>> Get CPU name. Big moment.
>> First run.
>> Next plan. We're going to try and adjust the cache speed a little bit. Maybe try
to tune the CPU speed up a little bit. >> We got second place again, but not quite
first place. What do you think's up? >> Well, if we look at the GPU Z tab here,
we have our 59. Is it 6x? It says it's at 16x, right? Gen 5
>> running it, >> but it's actually 8x. The um SSD is in
the wrong slot. I had it in the correct slot earlier. I don't know if somebody moved it or not.
>> It got pulled and put back in at one point. >> Mine isn't here, so we'll blame him.
>> I'm pretty sure we have it on video that it was him. >> Okay, then let's move that over and
let's try again. >> Whoa, whoa, whoa, whoa, whoa.
>> Whoa, whoa. You guys blamed me for putting in the S. I didn't put in the
SSD. Yeah, because you moved the 5090. >> I actually I actually know who put it
in. >> Oh, who? >> Unlike you guys.
>> It was not me. >> I'm not a filthy rat, so I would never
rat. Do Wait, do you do you have footage of who put it in? >> No, I I don't. Maybe. Editor, roll the
clip if there is one. >> Oh. Oh my god.
>> Seriously? Well, fortunately, it's only our first
run. In case you're curious about the finer details, we juice the CPU clocks a
little bit, juiced the cache, and this this is going to be it.
>> Ninth >> run. First try. >> Yeah, first try.
>> Man, it's going to be cool when we nail this. >> We got this >> on the first try.
>> Oh my god, it's so close. >> So close. >> Th00and watt BIOS,
>> huh? >> I think so. I think that will do it. >> On the next first try, we're going to
nail it. >> On the next first try. >> Hey, there it is.
>> Nice. First place. Good job. >> Taiwan number one. It's
>> only first time. >> You got a world record. >> The bad news is this took all day. So, I
guess we're not going to get to 3D Mark today. But hey, this is staying here.
