WEBVTT 00:00:00.000 --> 00:00:05.400 Just about 20 years ago to the day, my wife, Yvonne, took me shopping for my birthday. 00:00:05.400 --> 00:00:09.000 My present, a window-mounted air-conditioning unit 00:00:09.000 --> 00:00:13.040 that I promptly disassembled on the lawn so that I could chill my gaming CPU 00:00:13.040 --> 00:00:17.960 to sub-zero temperatures. She a keeper or what? Anyway, it's my birthday again, 00:00:17.960 --> 00:00:21.480 and this time I decided to spend a little more 00:00:21.480 --> 00:00:25.200 on my air-conditioner. How much? 30. 00:00:25.200 --> 00:00:30.280 Oh, that's actually a thousand. What? We already have numerous exotic coolers, 00:00:30.280 --> 00:00:35.400 including an industrial water chiller right there. Why did you spend $30,000 on this one? 00:00:35.400 --> 00:00:39.160 Because seeing this unique item, 00:00:39.160 --> 00:00:43.600 hand-built by overclocking legend, Charles Fuggerworth, 00:00:43.600 --> 00:00:47.900 is what inspired me to learn about sub-zero cooling in the first place, 00:00:47.900 --> 00:00:52.960 which is what led to my PC tuning obsession, which is what led to me standing here today. 00:00:52.960 --> 00:00:57.560 And you know what the craziest part is? His price for this thing, like literally, 00:00:57.560 --> 00:01:01.440 me one that inspired me. It's not even unfair. 00:01:01.440 --> 00:01:05.440 While most chillers use a single compressor and refrigerant, 00:01:05.440 --> 00:01:10.240 this is a cascade system and uses a total of three compressors, 00:01:10.240 --> 00:01:15.240 not to mention unobtainium gases to reach ungodly low temperatures. 00:01:15.240 --> 00:01:19.640 This very unit has been used to set countless performance records over the years, 00:01:19.640 --> 00:01:23.080 including live on stage and until launch events. 00:01:23.080 --> 00:01:26.960 And it comes with an extra special perk, 00:01:26.960 --> 00:01:32.640 hand delivery from the man himself. Charles, who flew up here to help me unbox it, 00:01:32.640 --> 00:01:36.200 verify that it works, and talk me through what makes his creation, 00:01:36.200 --> 00:01:40.920 arguably, the greatest CPU cooler on the planet. 00:01:40.920 --> 00:01:45.760 You got my money, right? Uh, no, but you know who does? 00:01:45.760 --> 00:01:56.840 Our sponsor. I'm gonna pick some muscle. 00:01:56.840 --> 00:02:01.440 They're pushed on a screwdriver to not strip them out. 00:02:01.440 --> 00:02:07.440 Are you saying you don't think I have muscle? Yeah. What is it with everyone who's a guest on this channel? 00:02:07.440 --> 00:02:10.560 And they just immediately open with the sick burns. 00:02:10.560 --> 00:02:14.560 Next, are you gonna ask me if I can reach all the way up there? I should get you a little stool. 00:02:14.600 --> 00:02:18.760 You're not even that much taller than me. I am so excited. 00:02:18.760 --> 00:02:24.200 I haven't even seen a picture of this thing since back when I was like browsing extreme systems. 00:02:24.200 --> 00:02:29.080 Now, I dreamed back then of commissioning you one day 00:02:29.080 --> 00:02:35.000 to build something like this for me. And I remember you did a handful of commission builds, 00:02:35.000 --> 00:02:38.240 if I recall correctly, but like really a handful. 00:02:38.240 --> 00:02:44.440 How many of these have you actually built? 22 stages, one, this is the only three stages I built. 00:02:44.440 --> 00:02:48.000 So you're saying this is a completely unique item then? 00:02:48.000 --> 00:02:51.520 Correct. Only a very few of these have been attempted in the world. 00:02:51.520 --> 00:02:55.040 And what is the difference just further uninitiated 00:02:55.040 --> 00:02:58.480 between a two-stage and a three-stage? Well, most of the two stages 00:02:58.480 --> 00:03:02.360 have never really achieved 100 below zero Celsius. 00:03:02.360 --> 00:03:07.280 And as far as this one achieves 100 below zero, actually it exceeds 100 below zero. 00:03:07.280 --> 00:03:11.760 I mean, architecturally, two stages versus three stages, 00:03:11.760 --> 00:03:18.400 what's the difference in the level of complexity having two compressors, one kind of cooling the first, 00:03:18.400 --> 00:03:21.680 versus having three, one cooling the next one, 00:03:21.680 --> 00:03:25.280 cooling the next one? The guesstimates getting the third-stage gas, 00:03:25.280 --> 00:03:30.880 the uptending of the third-stage gas, first of all. You can get like a poly-cold or the Revco units 00:03:30.880 --> 00:03:34.440 and try to work with one of those three-stage gases, but you won't have the capacity. 00:03:34.440 --> 00:03:38.320 You'll have to buy several of them or have to supplement the third-stage gas and you won't have the capacity. 00:03:38.320 --> 00:03:42.360 So if I wanted to build like a sperm storage unit or something like that, 00:03:42.360 --> 00:03:45.440 I could get like a nice low temperature or something. Or a freezer, yeah. 00:03:45.440 --> 00:03:52.400 Right, but if I want to cool something that is actively kicking out 500, 600 watts of heat. 00:03:52.400 --> 00:03:55.760 Correct, correct, correct. I need this. Correct, yes. 00:03:55.760 --> 00:04:01.040 This is the only one. Right. I gotta tell you, I didn't realize how heavy it was. 00:04:01.040 --> 00:04:04.280 Yeah. Before we started, I gave it the old, okay, it couldn't be that. 00:04:05.780 --> 00:04:10.920 It's really freaking heavy. Literally, it's this or a vehicle. 00:04:13.280 --> 00:04:18.360 Everything about this thing screams 00:04:18.360 --> 00:04:22.040 hand-built in the best possible way. 00:04:22.040 --> 00:04:28.960 When I originally built this, I didn't have very much refrigeration experience, so I built all of my lines as the crow flies. 00:04:28.960 --> 00:04:35.720 I've been many, many, many years. I perfected everything as I went. Now, you said that others have attempted three phases. 00:04:35.720 --> 00:04:39.120 Yes. Has anyone succeeded that you know of? 00:04:40.120 --> 00:04:42.160 No, not with the balance. 00:04:43.520 --> 00:04:47.920 I've seen some other attempts, but I've never actually seen it in use. 00:04:47.920 --> 00:04:49.200 I'll get ready to catch it. 00:04:52.600 --> 00:04:56.000 Don't drop it on me, hey? All right, I'll hold it. 00:04:56.000 --> 00:04:59.640 Thanks. You can hold 350 pounds, right? 00:04:59.640 --> 00:05:02.680 Oh, yeah. This is light work. 00:05:02.680 --> 00:05:07.720 Now, I couldn't help noticing, Charles, that my brand new purchase has some dust and rust on it. 00:05:07.720 --> 00:05:11.560 No, it doesn't. What did this thing was? 25 years, 26 years. 00:05:11.560 --> 00:05:16.360 So she's been around the block. Been around the world, twice, three times now. 00:05:16.360 --> 00:05:19.760 How would you rate this packing foam, Linus? Zero out of 10? 00:05:19.760 --> 00:05:22.080 Oh, well, let's hope I got here in one shape. 00:05:23.280 --> 00:05:28.000 That's fine when you made it here. When it's crate-chipped like this, realistically, 00:05:28.000 --> 00:05:33.080 that's not doing anything, it's just sitting on top of it. I'm just having fun at work. 00:05:33.080 --> 00:05:34.680 I know, I'm sorry, sorry, sir. 00:05:36.080 --> 00:05:36.920 That's better. 00:05:39.400 --> 00:05:42.480 I'm waiting for the camera to stop rolling. Keep it rolling. Stop it. 00:05:42.480 --> 00:05:44.160 You can't hit me while it's rolling. I guess. 00:05:47.000 --> 00:05:50.080 Sorry, how many power cords? Three. 00:05:50.080 --> 00:05:54.080 How much power does this thing draw? 45 amps, at max. 00:05:54.080 --> 00:05:59.320 Over 5,000 watts? Could be. What do you mean could be? 00:05:59.320 --> 00:06:03.200 So why does it need to draw 5,000 watts when it's only cooling 500 watts? 00:06:03.200 --> 00:06:06.400 Yeah, professor. Overkill. 00:06:08.640 --> 00:06:11.880 I didn't want to undershoot, that's okay. 00:06:11.880 --> 00:06:15.680 Okay, but in all seriousness, there are efficiency losses, 00:06:15.680 --> 00:06:19.200 especially as we make our way through multiple stages. 00:06:19.200 --> 00:06:24.000 So our main stage, our biggest one that cools the second, 00:06:24.000 --> 00:06:29.720 that in turn cools the third, has to be absolutely enormous, monstrous overkill 00:06:29.720 --> 00:06:33.800 from my understanding then. Well, here, let's get it up on the table, 00:06:33.800 --> 00:06:39.440 and then maybe you can walk us through where all the gases flow, 00:06:39.440 --> 00:06:42.880 in order to make it work its magic. Here, I just want to get this under it, 00:06:42.880 --> 00:06:46.920 so maybe we can get some fingers under it so we can maybe lift it. Oh God, I don't want to get fingers under that. 00:06:46.920 --> 00:06:51.040 Oh wow, you really don't, because Charles, in his infinite wisdom, 00:06:51.040 --> 00:06:57.200 built it with sharp corners. It's designed that way, so you get a nice clean cut. 00:06:57.200 --> 00:07:00.360 Right, if it's a poor cut, it's hard to attach again. 00:07:00.360 --> 00:07:04.440 You want to take it off right at the segment. No, it's just for the stitches go clean. 00:07:06.040 --> 00:07:10.080 Are we doing okay? We're doing great. Let's get Linus's end on first, 00:07:10.080 --> 00:07:13.720 because he's by himself. I'm good. 00:07:13.720 --> 00:07:17.080 You're good? Yeah, I'm good. Okay, put your corner down. Okay. 00:07:17.080 --> 00:07:20.680 My fingers are now being squished, but that is okay. Do you need help? 00:07:23.160 --> 00:07:26.200 My fingers were stuck. It's good. 00:07:26.200 --> 00:07:29.480 No. Okay, there's stuff in here. You just, 00:07:30.920 --> 00:07:35.320 I'm glad you're here to tell me how it works. I found the three compressors, 00:07:35.320 --> 00:07:38.640 and I found the cold end that goes on the CPU. 00:07:38.640 --> 00:07:42.280 I found what looks like a K-Probe or something like that. 00:07:42.280 --> 00:07:47.760 That's a K-Probe? Perfect, so that's going to tell us what the temperature is at our VAP head. 00:07:47.760 --> 00:07:52.120 I'm going to need you to kind of walk me through it. So where's our first stage? 00:07:52.120 --> 00:07:56.880 This is our first stage compressor. This is a Danfoss SC-12 MLX, low temp compressor. 00:07:56.880 --> 00:08:00.840 It's basically a half horse compressor. So basically this is for sub zero temperatures. 00:08:00.840 --> 00:08:05.560 And it has R507, it's a common gassage you can use for refrigeration. 00:08:05.560 --> 00:08:09.920 So this gets about 40 below zero. And it runs into our heat exchanger back here, 00:08:09.920 --> 00:08:15.240 which is an electron brace plate heat exchanger, 40 plate. Okay, so then normally, right, 00:08:15.240 --> 00:08:18.520 you would have your condenser side, 00:08:18.520 --> 00:08:23.600 which is where you have your fans and your aluminum fins or whatever, right? 00:08:23.600 --> 00:08:28.640 And then you would have your evaporator side, which would, in the case of like an air conditioner, 00:08:28.640 --> 00:08:33.040 more aluminum fins and a fan that blows the cold air into the room for you to enjoy. 00:08:33.040 --> 00:08:36.360 Or in the case of our refrigerant based CPU cooler, 00:08:36.360 --> 00:08:41.160 it would go to the evaporator head, which would go to your CPU, but we're not doing that. 00:08:41.160 --> 00:08:46.040 Because this is a multi-stage, we're taking our cold side, our evaporator side, 00:08:46.040 --> 00:08:50.560 and we're going to a heat exchanger. So then that means this inside here 00:08:50.560 --> 00:08:56.280 is the cold side of stage one, and the hot side of stage two. 00:08:56.280 --> 00:09:00.480 So that refrigerant, which for stage two starts 00:09:00.480 --> 00:09:04.280 at negative 40C on the hot side. 00:09:04.280 --> 00:09:08.320 Okay, where does that go? Well, the hot side goes into the, it's called a desuper heater first, 00:09:08.320 --> 00:09:12.160 before it even goes into the heat exchanger. So I'm actually stripping off the heat 00:09:12.160 --> 00:09:17.200 before it goes into the heat exchanger. Oh, to make it easier for our first stage to cool it. 00:09:17.200 --> 00:09:21.120 To condense, correct. Oh, God. I'm bringing it down to ambient. So we pre-cool it. 00:09:21.120 --> 00:09:25.920 Correct. Brilliant. So where does it go from there? 00:09:25.920 --> 00:09:29.000 It actually goes into the expansion valve. Okay. 00:09:29.000 --> 00:09:32.720 And it goes into the second stage compressor. There's an expansion valve on this side. This is a pressure expansion valve. 00:09:32.720 --> 00:09:35.840 Yeah. And it has a little knob on the side over here 00:09:35.840 --> 00:09:39.320 that you can adjust. And... I won't. No, you don't have to. 00:09:39.320 --> 00:09:43.680 It's already preset. Oh, good. And then I don't see another heat exchanger. 00:09:43.680 --> 00:09:47.640 Oh, it's all built. It's all inside of here. Oh, so you're telling me then 00:09:47.640 --> 00:09:51.280 that we actually have two heat exchangers in here. Correct. 00:09:51.280 --> 00:09:56.760 One that is using the first stage to chill the hot side of the second stage to minus 40. 00:09:56.760 --> 00:10:02.500 Correct. And then one that's using the cold side of the second stage, minus 80, you said? 00:10:02.500 --> 00:10:06.180 Yes. To cool the hot side of the third stage? 00:10:06.180 --> 00:10:09.380 Yes. Which is at minus 80 Celsius. 00:10:09.380 --> 00:10:14.700 Now this, my understanding goes, is where kind of the black magic and the tuning 00:10:14.700 --> 00:10:17.940 and the unobtainium gases really come into play. 00:10:17.940 --> 00:10:23.780 Correct. Condensing the third stage gas. Okay. So I did notice that our third stage compressor, 00:10:23.780 --> 00:10:28.420 which is this guy over here, looks a little gruntier. 00:10:28.420 --> 00:10:31.700 No, it's exactly the same. They're all the same compressor. Wait, it looks bigger. 00:10:31.700 --> 00:10:36.900 No, it's all the exact same. Okay. I need to use whatever trick it's using with my wife. 00:10:38.900 --> 00:10:43.300 Ha ha ha ha. I did notice there are a few components 00:10:43.300 --> 00:10:46.980 that we haven't talked about much. Okay. We didn't mention the oil separators. 00:10:46.980 --> 00:10:52.540 Correct. What's their role in this system? To keep the oil separated from the system 00:10:52.540 --> 00:10:58.500 because we're working at temperatures that are sub zero and when you get the oil inside the lines, 00:10:58.540 --> 00:11:03.260 it can cause flogging and that'll cause the system to fail 00:11:03.260 --> 00:11:07.380 and you don't want the system to fail. No, I don't. One of the major problems that I had with my cascade 00:11:07.380 --> 00:11:14.260 was system volume. And one of the early things I did with the create system volume was I pig-tailed my line 00:11:14.260 --> 00:11:18.700 trying to think that I was adding volume to my system by adding- Oh, just making them a helix. 00:11:18.700 --> 00:11:23.740 Kind of like you do on the traces of a PCB to make sure that all the traces to the memory slots 00:11:23.740 --> 00:11:27.020 are at the same length, for instance. Right, but I'm trying to add volume to the system 00:11:27.020 --> 00:11:31.680 by adding more length to the thing, but I wasn't very knowledgeable at the time. 00:11:31.680 --> 00:11:35.100 But in time, I realized I could get suction accumulators 00:11:35.100 --> 00:11:40.540 and add more volume to the system. And so what these do is these are like right before 00:11:40.540 --> 00:11:44.660 the line set and they add more volume to the system. 00:11:44.660 --> 00:11:48.100 Okay, so these are just a giant reservoir, essentially. 00:11:48.100 --> 00:11:51.140 Reservoir, exactly. Of refrigerant gas. Correct. 00:11:51.140 --> 00:11:55.060 Wrap my brain around this one. And this time I don't actually know the answer before I'm asking you. 00:11:56.060 --> 00:12:00.420 How does having a large volume of the gas 00:12:00.420 --> 00:12:03.500 that isn't actively participating 00:12:03.500 --> 00:12:07.060 and being cooled as far as I can tell, it's not insulated. 00:12:07.060 --> 00:12:11.020 How does that help us? Boy, oh boy, oh boy. I don't know how to explain this 00:12:11.020 --> 00:12:13.580 that you guys can understand it. Oh. 00:12:14.580 --> 00:12:18.980 Damn! Damn! 00:12:18.980 --> 00:12:22.220 I always had capacity issues. 00:12:22.220 --> 00:12:25.420 And I always had to add more gas to the system. 00:12:25.420 --> 00:12:31.020 And I had a problem with adding more gas and then having the pressures on the system too high. 00:12:31.020 --> 00:12:35.980 So in order for me to add more gas and not have the pressures too high, 00:12:35.980 --> 00:12:39.180 I had to increase the volume. 00:12:39.180 --> 00:12:42.180 And so by adding the suction accumulator, solve that problem. 00:12:42.180 --> 00:12:47.100 So it's almost like buffering you against pressure volatility, in a sense. 00:12:47.100 --> 00:12:50.260 Like what role is it playing in there? More gas. 00:12:50.260 --> 00:12:54.900 I need more gas to go to the block. Okay, but if the gas isn't actively being... 00:12:54.900 --> 00:13:01.460 More liquid. I need more liquid to go to the block. So it gives you just more fluid overall 00:13:01.460 --> 00:13:05.180 because liquid is so much denser than gas. 00:13:05.180 --> 00:13:08.580 But then when you weren't running it, 00:13:08.580 --> 00:13:11.660 the pressure would be astronomical because it's all in its gashes form. 00:13:11.660 --> 00:13:15.620 Right. Well, I had to put more gas in the system and the pressure would go up higher. 00:13:15.620 --> 00:13:18.540 And then I went into like a... Understood. 00:13:18.660 --> 00:13:23.580 This just gives us enough. So realistically, when we're running, 00:13:23.580 --> 00:13:27.300 this is not like high density gas storage at that time 00:13:27.300 --> 00:13:31.780 because so much of it is in liquid form. But this gives it somewhere to go 00:13:31.780 --> 00:13:35.620 when it all becomes gas. Right. Okay, I think we got it. 00:13:35.620 --> 00:13:40.020 Yes. See, I could understand that. Yeah, great explanation. 00:13:40.020 --> 00:13:43.460 There is one thing we missed. Yes. 00:13:43.460 --> 00:13:46.540 Do I need to pay attention to these? Like if these go to the red line, 00:13:46.580 --> 00:13:49.780 do I freak out and pull all the plugs I like? No, no, no. 00:13:49.780 --> 00:13:55.860 These just let me know, like if the second stage and the first stage are running, so if my pressures go up, I can pull the plugs. 00:13:57.020 --> 00:14:00.060 Basically, when we shipped it, I could, you know, like when you took the picture, 00:14:00.060 --> 00:14:02.340 I can know if the gases leaked or not. 00:14:03.540 --> 00:14:07.060 In the future, like we can mark the pressures right now 00:14:07.060 --> 00:14:10.860 and like a year from now, we can see if we lose the pressure and we can charge the system. 00:14:10.860 --> 00:14:15.060 Right, but not the third stage. I mean, do you have a bottle of the third stage? 00:14:15.060 --> 00:14:19.060 No. Sure, yeah, yeah, yeah. 00:14:19.060 --> 00:14:22.460 No. It's kind of making it sound like there's a bit of a, 00:14:22.460 --> 00:14:27.180 like fire up procedure for this. Correct, there is a procedure for firing up. 00:14:27.180 --> 00:14:30.820 Can we do it? You want to fire it up? I mean, yeah. 00:14:30.820 --> 00:14:34.660 Okay, do we pull some cords and we can fire it up? All right, so this is going to take about 10 minutes 00:14:34.660 --> 00:14:40.260 to come down. Well, are these labeled? No, I just know, but we'll label them before we go. 00:14:42.660 --> 00:14:46.420 What should I be monitoring here? I mean, obviously I can see some of my fluid 00:14:46.420 --> 00:14:51.020 flowing through here, am I looking at pressures? How do I know when it's down to temperature? 00:14:51.020 --> 00:14:54.580 Okay, so right now we just got to wait a few minutes and we're going to watch for some ice build up 00:14:54.580 --> 00:14:59.460 on the first stage. The ice will build up right here on the backside of the suction line. 00:14:59.460 --> 00:15:03.340 Okay. And so once we get a little bit of ice built up on there, we can fire up the second stage compressor 00:15:03.340 --> 00:15:07.380 and we watch for the same thing on the second stage compressor, we watch for a little bit of ice building up on the back of the second stage compressor. 00:15:07.380 --> 00:15:12.100 Now riddle me this, if someone were to irresponsibly 00:15:12.100 --> 00:15:15.900 fire the second stage compressor when we are not cooling 00:15:15.900 --> 00:15:19.900 the first stage, what happens? I don't know, never done that. 00:15:19.900 --> 00:15:23.540 Neat. Now let's say I don't like learning things the hard way. 00:15:23.540 --> 00:15:26.900 Right? Where are the do not touch no touchy places? 00:15:26.900 --> 00:15:30.300 This would be one of them. Oh, there's a thing that was burned on there. 00:15:30.300 --> 00:15:33.660 Yes, this would also be one of them. Yes. And this would also be one of them. 00:15:33.660 --> 00:15:37.380 Okay. That's the only three spots that are danger zones. 00:15:37.380 --> 00:15:41.500 Oh, look at that, hey, we're frosting. Now, should I care about that at all? 00:15:41.500 --> 00:15:44.740 Like a little drip and rust? No, no, no, once I fire up the second stage, 00:15:44.740 --> 00:15:48.380 that'll evaporate. And I assume the second stage is the middle one? Yep. 00:15:48.380 --> 00:15:54.020 Good assumption. All right. Go for it. Okay, it's a little bit not quite straight, but hey, 00:15:54.020 --> 00:15:58.700 aren't we all? Okay. So when I plug in this third stage, this spot, this one, actually this one's gonna drop. 00:15:58.700 --> 00:16:03.260 Yeah. And then about 15 or 20 seconds later, 00:16:03.260 --> 00:16:08.420 this is gonna start to drop. Oh, the temperature at the evap head for the third stage. 00:16:08.420 --> 00:16:11.540 And this is where we cool our CPU. Okay. 00:16:11.540 --> 00:16:15.580 There we go. Big moment. Here we go. It's not that flat, Charles. 00:16:15.580 --> 00:16:18.780 What do you mean? I just mean, you know, the quality of the workmanship. 00:16:18.780 --> 00:16:22.900 It's perfectly flat. The quality of the workmanship is just, you know, it's a. 00:16:22.900 --> 00:16:28.860 Sub-zero. In all seriousness, when you have this level of cold 00:16:28.860 --> 00:16:33.700 up against the CPU, the macro flatness of the surface 00:16:33.700 --> 00:16:37.620 does still matter. You don't want like a big bump coming out of it 00:16:37.620 --> 00:16:41.900 that's giving you bad contact, but little pock marks like that, 00:16:41.900 --> 00:16:45.320 they don't actually matter. You might want to resurface it. Oh, whoa. 00:16:45.320 --> 00:16:49.180 She's really going now. So it'll stop around negative nine until we put a load on it. 00:16:49.180 --> 00:16:54.020 Negative 90. So you're saying it goes lower when we put a load on it? 00:16:54.020 --> 00:16:59.080 Yeah. This is a thermal expansion valve on this side here. The more load we put on it, the more it'll open the valve. 00:16:59.080 --> 00:17:03.580 You're at negative 69, baby. Whoa, buddy. It started sublimating. 00:17:03.580 --> 00:17:08.260 So you're saying if I licked it, that would be bad. Your tongue would stick to it instantly. 00:17:08.260 --> 00:17:11.740 Oh, that's so tempting. Yeah, we have to give you one to the hospital. 00:17:12.980 --> 00:17:16.700 What are we at? Negative 90? Negative 83. Oh, we still got boys to go. 00:17:16.700 --> 00:17:21.180 Oh, okay. Oh, okay. So we would wait until she's completely down to negative 90 00:17:21.180 --> 00:17:25.220 before we put a load on her. We don't have to. It doesn't matter. It will just expansion valve and then. 00:17:25.220 --> 00:17:30.020 Yeah. Wow. Eh, eh, eh. 00:17:30.020 --> 00:17:33.340 Woo. It's snowing, boys. 00:17:33.340 --> 00:17:37.380 So when this is bolted to the CPU and the CPU is put under full load, this will drop about one or two degrees, 00:17:37.380 --> 00:17:40.900 maybe even three degrees. And another critical thing 00:17:40.900 --> 00:17:45.580 that is so cool about this system is that it won't go up. 00:17:45.580 --> 00:17:53.100 So our temperature stability compared to basically any other solution is unheard of. 00:17:53.420 --> 00:17:56.460 Like even when you're dealing with liquid nitrogen, for instance, 00:17:56.460 --> 00:18:02.140 one of the big hassles of overclocking with LN2 is that you are constantly micromanaging 00:18:02.140 --> 00:18:06.100 the liquid nitrogen in your pots because you don't actually want your CPU 00:18:06.100 --> 00:18:09.380 necessarily at negative 150 degrees. 00:18:09.380 --> 00:18:13.340 That can be problematic. You can run into cold bugs. So you got to like, you got to bring it up 00:18:13.340 --> 00:18:17.460 in order to boot. You got to put it back down when it's time to do your run. 00:18:17.460 --> 00:18:19.380 With this system, we're just 00:18:20.740 --> 00:18:24.100 Exact. At minus 90 all the time. 00:18:24.100 --> 00:18:29.140 Idle, load, doesn't matter. No bulls***, no micromanagement. 00:18:29.140 --> 00:18:32.220 One thing I don't have to deal with is crashing a lot. 00:18:32.220 --> 00:18:35.620 So once we're stable, we're good to go for the full bench session. 00:18:35.620 --> 00:18:38.820 We can bench for 16 hours straight and like crash once or twice. 00:18:38.820 --> 00:18:42.280 Okay. Now it's going to be a separate video, but can we tease them a little bit? 00:18:42.280 --> 00:18:48.300 Can you show us one of these golden chips, which had been rumored for many years to exist. 00:18:48.300 --> 00:18:51.420 It's been rumored that reviewers get golden samples, 00:18:51.420 --> 00:18:54.500 hand selected by Intel. That's bulls***. We don't. 00:18:54.500 --> 00:18:57.700 He does. Can I see one? Sure, sure. 00:18:57.700 --> 00:19:02.460 Well, it looks like any other 1400KS. 00:19:02.460 --> 00:19:06.220 How do you know it's special? It's probably been like one of... 00:19:06.220 --> 00:19:09.660 Some number. Now, when you have a chip of this quality, 00:19:09.660 --> 00:19:13.860 I don't think it's a big secret that Intel has had some degradation challenges 00:19:13.860 --> 00:19:18.380 with their 13th and 14th gen silicon. Do you kind of do the early testing 00:19:18.380 --> 00:19:21.580 with your sacrificial lambs and then save your best chip 00:19:21.580 --> 00:19:24.880 for like when it's time to break the record? Yes. Okay. 00:19:24.880 --> 00:19:31.900 I guess my only last question then is why on earth are you selling this? 00:19:31.900 --> 00:19:35.460 I'm going to build another. I already started. Oh. 00:19:35.460 --> 00:19:38.820 So actually, I'm kind of funding V2 then in a way. 00:19:38.820 --> 00:19:42.740 Are you using the proceeds to fund the next one? 00:19:42.740 --> 00:19:46.460 Yes. All right. It's the second one going to be so much better 00:19:46.460 --> 00:19:49.980 that I'm going to feel like I need a new one. You're going to have to tell me 00:19:49.980 --> 00:19:51.500 because it's going to be yours. 00:19:53.980 --> 00:19:57.100 Wait, what? Yeah, I'm building you a second one. I know I haven't told you yet, 00:19:57.100 --> 00:20:00.340 but I had to break it to you somehow. You are? 00:20:00.340 --> 00:20:03.780 Do you know about this? No. Does anybody know about this? 00:20:03.820 --> 00:20:07.020 Really? Oh, we're building you a second one. 00:20:07.020 --> 00:20:10.700 When was this decided? I thought we were building you a second one. 00:20:10.700 --> 00:20:14.100 Yeah. Oh, not a three stage though. Oh, okay. 00:20:14.100 --> 00:20:17.660 What? We're building a single stage, I guess. 00:20:17.660 --> 00:20:20.380 What? It just needs another $30,000. Oh, yeah. 00:20:21.380 --> 00:20:25.060 Okay, no, no, but what? No, no, I'm sorry. Hold on. 00:20:25.060 --> 00:20:28.180 What's the plan? We're building a single stage. Oh, we're talking about that. 00:20:28.180 --> 00:20:31.620 Right. Yes. A custom single stage. Yes. 00:20:31.620 --> 00:20:35.180 Exotic single stage. We actually have a couple more things coming. 00:20:35.180 --> 00:20:38.500 So this is setting up a whole series with Charles. 00:20:38.500 --> 00:20:42.420 We're doing the unboxing here. Part two, we're gonna set some world records. 00:20:42.420 --> 00:20:46.220 Part three, I'm gonna do an everyday 00:20:46.220 --> 00:20:50.300 sub-zero CPU and GPU build for home. 00:20:50.300 --> 00:20:53.780 That's what you're talking about. Yeah, and plus, I'm gonna build another three stage 00:20:53.780 --> 00:20:56.980 myself. For yourself, okay. Most likely, I'm gonna build a two stage. 00:20:56.980 --> 00:20:59.980 I'm happy to be part of the journey no matter what you build next 00:20:59.980 --> 00:21:03.100 because I just love seeing enthusiasts 00:21:03.100 --> 00:21:06.180 go out of their comfort zone and just do cool shit like this. 00:21:06.180 --> 00:21:11.740 And it's been such a pleasure to have you here and it's gonna be such a pleasure to continue 00:21:11.740 --> 00:21:15.660 to have you here as we work our way through all of the incredible sub-zero adventures 00:21:15.660 --> 00:21:20.340 we have planned. Well, thank you for helping me on my journey and your proceeds will definitely go towards 00:21:20.340 --> 00:21:25.780 another build and I'll make sure it's better than this one. And you know what else is gonna be better than this one? 00:21:25.780 --> 00:21:29.660 Some future segue to our sponsor. If you guys enjoyed this video, 00:21:29.660 --> 00:21:34.260 why not check out the first time that I got to play around with refrigerant cooling 00:21:34.260 --> 00:21:38.380 with the LDPC V10, I think it was from little devil. 00:21:38.380 --> 00:21:42.340 It was a PC case that had a single stage CPU cooler 00:21:42.340 --> 00:21:47.660 built into the basement of it. It was woefully impractical, but very cool.
