Oh, great. We don't even have any thermal compound,","speaker":null,"is_sponsor":0},{"start_s":358.92,"end_s":362.84,"text":"but here's the thing. You can't use just any thermal compound.","speaker":null,"is_sponsor":0},{"start_s":362.84,"end_s":366.44,"text":"What would you go with? Probably some thermal grizzly cryonaut. And the reason for that","speaker":null,"is_sponsor":0},{"start_s":366.44,"end_s":372.5,"text":"is that certain thermal compounds might perform great at ambient temperature or hot,","speaker":null,"is_sponsor":0},{"start_s":372.5,"end_s":375.68,"text":"like a liquid metal, for instance, highly thermally conductive,","speaker":null,"is_sponsor":0},{"start_s":375.68,"end_s":378.94,"text":"but here's the thing.

You just, you become not into the mess","speaker":null,"is_sponsor":0},{"start_s":393.04,"end_s":396.04,"text":"and it just goes on like this. Hold on one more second here. We got one more piece.","speaker":null,"is_sponsor":0},{"start_s":396.04,"end_s":400.28,"text":"We got a new piece of neoprene here. Right, for around the bottom here.","speaker":null,"is_sponsor":0},{"start_s":400.28,"end_s":403.44,"text":"Correct, correct.

Oh, sure.","speaker":null,"is_sponsor":0},{"start_s":407.04,"end_s":410.24,"text":"And then that just goes on there or a little something like that. Once you get to there,","speaker":null,"is_sponsor":0},{"start_s":410.24,"end_s":413.88,"text":"then we'll bring it down another, about a centimeter. About a centimeter, okay.","speaker":null,"is_sponsor":0},{"start_s":413.88,"end_s":419.92,"text":"Now it's funny. You were making fun of me the other day for using a rando mixture of imperial and metric units,","speaker":null,"is_sponsor":0},{"start_s":419.92,"end_s":424.4,"text":"but I just heard you use a centimeter.

That's the 6000 C28.","speaker":null,"is_sponsor":0},{"start_s":436.24,"end_s":439.56,"text":"So just super tight latencies and good rated speed.","speaker":null,"is_sponsor":0},{"start_s":439.56,"end_s":442.8,"text":"Correct. With CPUs, you know, you guys would take the time","speaker":null,"is_sponsor":0},{"start_s":442.8,"end_s":447.8,"text":"and you would hand bin.

Here's my present. Previously on LTT, 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. An overclocking legend Charles Fuggerworth here gave me his personal guarantee that we will do it. So what are we waiting for? Well, we've got to prep the motherboard, we've got to insulate the socket, we've got to update the BIOS, we've got to upgrade the VGA BIOS, we've got to install the Windows, we've got to tune the Windows, and we've got to prep the VGA driver. And we've got to get the power cords. Oh, oh no, we've got those, we've got the power cords. We've got seven circuits to work with. Just seven? What, is that not enough? I think seven will work. Okay, as for the rest of it, well, 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. Before we can begin, one of the key enemies of subzero 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 PlastiDip, 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 of heating element. So counter-intuitively, you're heating the CPU area? Correct, correct, correct. It prevents moisture from building up on the backside of the board. Okay, and then what about the front? I use a little bit of insulation, just neoprene. Just kind of like this? Yeah, just a little bit of neoprene. Any glue or anything? No, no, no, I'll eat. And then I use WD-40, WD-40 specialist. Shut up. No, I- You put WD-40 in your CPU socket. I spray it directly in the socket, and 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. 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 gonna be using the first board today though, and it looks great. Like, we could probably run Sub-Zero for hours, days at a time on this. But there is one small problem. Noctua probably doesn't make a secu-firm mounting bracket for your Cascade Chiller, so how do we get the thing on the thing? I make my own custom 3D printed brackets. These are for different sockets. That's for X299. Oh, cool, okay. And this is for AMD, AM5, AM4. Oh, cool. Hey, got the Extreme Systems logo on there. Now, it looks like you're using, oh, crap. Nylon. It's the, oh. That's the HP Multi-Jet Fusion. Wow, it feels, you can't break it. Feels great. It's the HP Multi-Jet Fusion 4200. Like, 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? Sure. You said you wanted a screw? Yeah, yeah. So just pull it back a little bit. Expose the O-ring. Uh-huh. 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? 20 years ago. Super cool. And can you kind of describe it for us? Like, is it a maze style or like, what are- This is a spiral evap-er. This is the prototype spiral evap-er. This is the first one I ever made. What's better about the newer ones? The newer ones are a thinner material. So better, 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, goes right on. Goes on like that. Install the O-ring. Oh, that's actually shockingly elegant. Now, are these O-rings one-time use? Did you just- No, no, no, 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, come on. 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 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 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 cryonaut. And the reason for that is that certain thermal compounds might perform great at ambient temperature or hot, like a liquid metal, for instance, highly thermally conductive, but here's the thing. We're not gonna be at room temperature. We're gonna 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. I guess you do this for enough years. You just, you become not into the mess and it just goes on like this. Hold on one more second here. We got one more piece. We got a 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 because these are dual dim board. Oh, sure. And then that just goes on there or 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 and 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 sets from Patriot. That's the 6000 C28. So just super tight latencies 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 bin those further? We've been them further. Okay, so this is a particularly nice kit of this. Correct, super binned. God binned. The last thing we're gonna need before we can fire up our bench is a GPU. Now, we're not gonna 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 subzero prepped with plastic 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 subzero speed. So we're probably just gonna 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 negative 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 gonna hook them all up in line with, here we go, our power. Ah, it's alive. Oh, what do we got? What do we got? Oh, 116.7 volts. 941, 941 watts. 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 watts. Now that the first two phases are kind of settled in, they're at 700, 750 watts each, but we haven't even added the third phase yet. I can't read it. What does it say? Said 250. Oh, that's not bad. And then it jumped to 1,100. That's a lot 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, it's actually his memory that we're borrowing. And board. So do you wanna 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. Well, multi-core enhancement, we are going to enable it and remove all the limits. We're going to set manual for AI overclock tuner. NPU boost level three, DRAM timing control. The Apex has a lot of nice, useful profiles. You have 9,600 gear four for the 24 gig sticks. Oh, cool. 9,000 for the 16 gig sticks and the 24 gig sticks. So we're gonna run 9,000 on the 24 gig sticks and just leave it at that. So you don't even have to 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 an Apex, like a top tier board? I think the lower end boards do have some features. The Strix does have that. The Strix has that as well, very good. We aren't as aggressive. I don't think you're going to be running 9,000 on a four dim stick. Well, the cache is 49. 49? Seems high, but. If you want to go 48, that's fine. All right, we'll go 48 for the start. We'll take it to 48. Hacking the main frame. So the D2D ratio is the interconnect. There 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. Memory band with really high speeds, with like no NPU boost on this. That's right, the IMC is on a separate chiplet, isn't it? Latency is kind of an issue. Intel, okay, you'll get them next time, boys. It's a very strange design. It's effectively a monolithic CPU that is a chiplet on a single die. So we're going to change our V-Core to 1.35 volts. That's all we need, huh? You tend to not need as much voltage as you would going to 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 they're going to ship to consumers. 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 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. 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 PCMark 7, it'll have the screen up with the result. We're going to open up four copies of the CPU ID. We're going to set up four boxes. We're going to set up the CPU, the amount of the board, the memory tabs. And then we're going to do a screenshot. And then we're going to have a world record for you. That easy? That easy. You got to be kidding me. Well, we got to save the result. All right, here we go. PCMark 7, let's go boys. Wait, before we actually do the run, I mean, can we just put it under load and see how stable the temperature is? Okay, okay. W prime? Yep. Okay. Are we at 64.4? Yeah, okay. It's a very popular older benchmark. Wait. We got down. 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. It is so cool. And we're going the other way now in temperature. Look at this. Yeah, he's right. That's the wrong way. He's right. We're going back down. We went from negative 104.4 to like 0.5, 0.6, back to 0.5 still. It'll fluctuate a little bit. We're within like 0.3. 0.5, yeah. But with the e-cores on and running around 5.8 or 5.7, we might have like a two degree fluctuation. And that's with a 285K. With the Raptor Lake, we might have like a four degree. Right. He'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. So this is a thermal expansion valve right here. And this is a expansion valve that responds under load. So now it'll go back down in temperature again as 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. Cause 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 running 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, my understanding is the temperature of the refrigerant should be basically the same ish. 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 really see how much he runs benchmarks. Is it 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 four is Riker. Riker, sorry. He's still working his way through his backlog. Yeah. Okay, so we're ready. Okay, so we're gonna 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. It'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 Ellen too 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. Right. The cascade, you can just rerun this thing all day long and have it consistent runs every single time. So it's gonna be extremely hard to catch your score. Right, got it. It's gonna be extremely hard. My score. You're gonna be on the world record rankings for a long time and let the other guys chase you down. Good luck. Oh, 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. Yeah. That's weird, that's not memory. Yeah, because it meant that that could be memory. That is CPU, I know for a fact it is. That wasn't CPU, we'll need a minute. Now you guys tuned one more thing. This is our third run. What did you guys change? 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 gotta be 15,017. Oh. 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 there. And now we play the waiting game. Here we are, run number two. Well, three, but who's counting? Oh no. Oh, it was data file corruption. Yeah. So we made it this far and then it's upset that it doesn't know the CPU name. Third time's 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 can be the first. All right. Oh, it went down. How'd we go down? You're on frame for a second to go up. You didn't put any GPU clock on it, man. Oh, 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 gonna 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 16X, right, gen five. Running it. But it's actually 8X. The SSD is in the wrong slot. 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. Linus isn't here, so we'll blame him. Yes, 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 SSD. I didn't put in the SSD. Yeah, because you moved the 5090. 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. Wait, do you have footage of who put it in? No, 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 just the CPU clocks a little bit, just the cache, and this is gonna be it. Ninth run. First try. Yeah, first try. Man, it's gonna be cool when we nail this. We got this. On the first try. Oh my God, it's so close. It's so close. Thousand watt BIOS? Ah? I think so. I think that would do it. On the next first try, we're gonna nail it. On the next first try. Yay, there it is. Nice, first place. Good job. Taiwan number one. It's only first try. You got a world record. The bad news is, this took all day, so I guess we're not gonna get to 3DMark today, but hey, this is staying here, so you can expect to see plenty of shenanigans make sure you absolutely pound that subscribe button. Like I'm talking a hole in your TV or monitor so you don't miss any of the future sub-zero updates with Charles coming up here in the future to build a single phase, and also just, I don't know, man, Elijah, we're gonna have to play with this thing like lots. Sounds good to me. Just like I'm gonna play with our sponsor. It's weird, right? Yeah. If you guys enjoyed this video, maybe go check out part one where we unboxed what I am calling the Beast, which it turns out, isn't that exactly what you call it? Yes. Cool. We both named it the same thing. Ironically, yeah. Good job on the world record."}
