The ACTUAL Computer from the Saturn V Rocket - ft. SmarterEveryDay

1. and welcome to the wine show. Ladies and gentlemen, we're a little bit late, but at least we got the video done right. No, no, we didn't we didn't. Actually it was all for nothing. I'M really frustrated. We are doing a thermoelectric cooled computer, but instead of doing it kind of the like the the janky way well to be clear, it's still janky, it's probably the janki's thing we've ever made. We recently did a video on Peltier or tech cooling, with the basic conclusion being that it's a giant boatload of suck. We spent about $ 300 to get pretty much the same, not actually worse, performance than with a standard water, cooling, radiator and at the fantastic cost of a couple hundred watts of power consumption. So we've taken all those learnings and we have crumpled them into a big ball and put them in a fire, because today's video is all about taking Peltier, cooling and amping it up a notch pun intended this right here is a 545 watt tell chain, thermoelectric cooling Module so we are gonna Pump, a walk 10 occur, insert we're gonna have a hot side. We'Re gonna have a cold side, and we are gonna have potentially a real good time or a real bad time, either way. It'S a great video right. Speaking of great videos, this great video is brought to you by our sponsor. I fix it. The I fix it. Marlin screwdriver set features, five specialty, precision, screwdrivers and you can get yours at the link in the video description, [, Music ]. So I noticed that you designed a water block. Is there a reason that other than flexing check my source the new workshop here, that we didn't just use a standard water block and put it on top of the tech yeah? So a water block like this, even though it looks size- wise like it's, should be a pretty frigid yeah CPUs only on the die. They really create a lot of heat. No water blocks only really cool the center right, so the actual fin structure of a typical CPU water block is only about this big. So what happens then to our tech? If we only cool the center of it, it just won't be as efficient and it's gonna get really hot around the edges got. Oh, we had to design this fairly massive block like if you it's hard to get a sense of the scale when we're looking at it like. So how big is it the scale like these mounting holes right here? Yeah are the same, but but the actual site we're actually going almost right to it. So it's quite a bit like yeah, it's like about this big, so we have a 65 millimeter in our channel thing, which is just a bit larger than the diameter of this. So it should work pretty well unless it doesn't another reason we had to design. Our own block was that it needs to have some special functionality like okay, it's great in theory to say you stick this on top to cool the hot side and then the CPU gets cooled by the cold side. But what keeps this in place? Not just in place but clamped against the cooling element so that it gets optimal thermal transfer. Well, that's where this type of sandwich design comes in, so you can see. We'Ve got our cooling element here on the top, and then you can actually see this very nice attention to detail by the way. I think I like this, the Polli it's going and everything you can see. The Peltier element is sandwiched in between. Then we've got these right here. These bolt throughs are going to hold these pieces together, really really tightly and bind them to this. This cold plate at the bottom. So for much the same reason as we can't just attach a tiny cooling element to the top of the hot side of the Peltier and expect optimal efficiency. We can't take the cold side of the Peltier and put that against a tiny, little CPU and hope that we're getting the most cooling out of it. So we need to have something to spread the cooling and that's gonna be another copper plate on the bottom. That it's also sandwiched around it yeah. So another problem that we have is that if you just put this on a full-bore like, if you just attach it to a power supply sure it's gonna cool down really really fast, I'm really cold yeah. So we could end up with condensation. I mean really condensation yeah condensation a lot to get water around your CPU, not a great time. So that's why we have this guy right here, it's a PID controller, and do you know what PID is? Actually, I don't know what it stands for proportional, integral and derivative okay. So in a nutshell, this is like an on-off switch. Temperature goes in and it says yes that is okay or no. That is not okay, and if the temperature is okay, then it sends a signal to this guy and says: don't turn on the Peltier, and if the temperature is not okay, it's too high it's higher than what we want. You know say: hey hell, shake kick on and this will turn on our block yeah. So that's all well and good, although it's a bit sketchy to just have all of that electronic stuff put on the table, mm-hmm yeah. So all that's going in this nice little box right here, fun, which you might have noticed this doesn't quite fit. So we can either cut a hole in the top and have a big old fan, or we can cut a slot and have it just sticking out the side. I'M a fan of that one, because it's easier, hmm, okay, it sticking out the side cool. You might be looking at this rather primitive block and thinking there's no way that's going to cool a 545 watt Peltier, so I'm going to prove it should be fine using solidworks flow simulation for the simulation. We'Ve got a 545 watt heat source, some thermal paste and a fluid input with the flow rate of a d5 pump. The only real assumption that I've, the water would reach a steady state temperature of about 42 degrees, which seems reasonable enough. Given the huge radiator that we're using after running the simulation, we can see that the flow does a reasonably good job of going through the fins and the water, ASIS and temperature by about two degrees, while making its way from one side to the other. A temperature of the Peltier Rises quickly at first, but it

2. hits steady-state at around 54 degrees after a minute or two, which seems slightly low to me, but basically confirms that if we have, a problem is probably not due to bad cooling. Oh man, this is gonna, be like the most full send video we've done in a while, but it's done right, it's like done, but not to like, where I normally would get it before a video. Are you sure yeah? So we have the bottom bit. This also known as the base. Yes, the base, yep CPU contacts, the bottom here, yeah Peltier, that's pretty flat yeah. Actually, you left the stuff, oh okay. Well, that explains it so yeah Peltier. It goes on there Wow, which way not sure we need to turn it on to find that out and there's okay, there's a little trace. That'S in there. That'S where our thermocouple goes. Okay, neat yeah! There we go, we've got the also Labbit yep, also left. All the surfaces were left in this okay and we're good to go all right. So why don't we get this mess assembled and see where we go from there yeah? We basically have two tasks to do here: okay, one: we need to make a water cooler gloop and maybe equip this motherboard for Sub Zero. Depending on how we're feeling - and the other thing is this sketchy box here, he needs to be turned into a sketchy box that works, so everything that needs to be here is there, but none of it is so none none of it soldered yeah, so they get To watch off solder and cringe again, yeah they're gonna be really happy about that. So this right here is our solid state relay it's gonna just turn our tech on and off, based on how cold it is, and if it's gonna cause condensation and crap pretty much all it's going into there. We have these two power supply leads that they're, just Kayla, Maude, cable extensions goes in. There goes to the solid state relay and then out through this port here to the Peltier and should be good okay. So I've got a bit of an update for y'all. First of all, here is our weight. Update. Number two is this: is the radiator Alex was talking about, so this actually had a dedicated video on the channel like five years ago or something like that, but it's the phobia G changer 1080. Basically, it's three triple 120. Mil rads glued together to make for a nine by 120 millimeter radiator, so we're gonna we're gonna pop that, like it's hot and it's gonna cool things down good news, everyone, oh! What'S up, I found the perfect fans to use for our radiator here. These are actually the ones from whole room water, cooling from the last setup that we did. That was this ridiculous and all of these someone who disassembled it just left all of the screws like in the fans, so I don't even have to go, find radiator screws. I just put these in just wrapping builtwith.com/?https%3a%2f%2frouterhosting.com up the radiator here and that's it. However, many friggin watts of cooling that is these are dirty in like a really unsettling way: okay, Kate. Okay, so if I said I was five minutes from Waterloo completion, how close are we so everything in here is wired up, except that we need to do the painful bit. These two guys right here need to get the chop-chop and then what they get soldered together. Go to here and there and we're good to go. Oh, I see okay yeah. What else do we need to do? Besides that these two holes are experienced at the restaurant at all my favorite yeah? All right, I guess I'm gonna thread. This thing wait. We have a proper tap now, don't we do? We have a beautiful candle? Yes, whoa, yeah. Look at that thing! Look at this Wow, it's almost like it was made to do this. I'Ve never been this excited to have leverage. It only needs to be straight enough. Oh okay: well, this is not going well, so you won't be able to see it very well, but basically, I'm checking if the o-ring is squeezed against the plexi there and it looks like they are squeezed all the way around all right. I think I got him this box right here might be the sketchiest thing I've ever done like look at this. It'S just it's a bit of a mess. It'S a bit of a mess and we're putting like there's AC power in here. We'Ve got. What'S going to be nearly like 600 Watts going through freaking lever nuts, are we going to start a fire? It'S all within the rating? Okay, these are 32 amps rated at that and we're expecting 32 amps. So so, where do I connect this to so we need to put some wires onto here, yep and then those I was thinking, maybe just love or not them to those. So we can disconnect it if you want got it yeah soon, very soon. Okay, this is probably the cold side, so we're gonna gamble and I'm just gonna start assembling it. Alright. Alright, here comes all the thermal goop. This is disgusting. This stuff is nasty. Wait hold aside heat absorb, oh crap, I put it in upside down. Oh no oh, come on. How could I do that? We were gonna have to give up and start wearing show at some point here, though yeah. So what was that about? Not wanting to do this project the sketchy way cuz. I seem to recall you saying something about that. Oh I just remember like at the start. I had so many aspirations, so this would not be totally gee. I want to see this thing: fire up yes'm and I'm at the point where, even if it is literal fire, I will settle for it. Okay. So before I put this, I should show you guys to finished assembly. So here's where our water cools the hot side of the Peltier, which is sandwiched in there and then here, is where the cold side cools our CPU Alex. I can just put this on now right, yep and you're good to do your soldering on the leads for the text just like on here right, yes, sure, good, because that's what you're doing okay! This is not an amazing mounting mechanism, but I happen to have some screws. Oh, that are almost exactly the right length, so we are going for a hard mount that is gnarly. The good news is you're gonna get all that mounting pressure. You wanted yep the bad news is we might crack this piece of acrylic all right. Well, I'm gonna plug this in here. If I have to blast a Titan r-tx, I'm gonna be so pissed off all right. So it's a

3. power supply. I'M going to turn it on nothing died. Yet that's a good sign! So now I'm gonna put this on and if bad things happen, I'll just flick the switch and turn it back off. So three two one the fan didn't turn on should it have. Hmm. Imagine something being potentially miswired in there all right. We should probably go to you and show yep, okay, so heat. We don't want that. We want cool yay, we did it, so I can put this down yep. Okay, all right. So this right here is set right. Now it's just 220 degrees, mm-hmm, okay, but that seems fine. The solid state relay actually is working like. How do you know because this right here has a sketchy connection yeah? So if you pull it out, I'm here clicking and when you put it in you can hear it go cool coming in hot. What the hell! Well, I couldn't find a big jug, so that was such a good opportunity to like plug the merchant. Have the merch to I just need more, do you have the water bottle yeah, I know, but that also has my ice water in it. I was drinking that so we could have used like three all right. Let'S fill this thing. Okay. Well, there's one mug down all right: now the game is on. Oh, it's not leaking, so that's good! So is there water running through that loop yeah? Oh, you can also see that the bubbles are coming in here and they're, going not just through the middle, but also all the way around too okay, and so so the block design is working as intended. Oh my god. So that means the radiator is full, which is good. Oh ballsacks, my well, it's a good thing. Those fans were dead. The tech is so close to working. Yeah yeah, are you sure, not 100 %? As you said it a couple times now. I am slightly more confident this time. That'S nice, if only confidence was what it took to make something work, then the Hindenburg probably couldn't have been quite such a disaster. What how is that related at all? Well, they were confident it was gonna work. I bet, or they wouldn't have put a bunch of people in it yeah. It worked really well for quite a while. So we didn't run into this when we were using just a small Peltier, but it occurred to us that with so much power we might be running into over current protection limits on the PCI Express connector. So I thought well, why don't we use the eight pin EPS connector, which is the CPU power connector instead and see if we can overcome the problem? That way, and what's really convenient is that this is not by design, and you shouldn't ever do this. If you can avoid it but fun fact, you can jam an EPS male connector into a PCI Express female receptacle and all the pins will make contact. It'S just really like it's kind of a back to get it back out. So all we have to do is redo the the wiring here, your adapter, so it's actually a pretty it's almost a plug-and-play solution, plug in tray. More like it all right. Good luck! Everybody, oh well! Temperatures dropping temperatures dropping very fast, really at 20 degrees. 19. Don'T touch that we're at 16 degrees yeah, that's, definitely working okay, whoa, so we're ready to rock yes. Should we see if our relay works, because maybe there really wasn't the problem before well, if we want to just jam the other ones into this than the other power supply? Might work wait? Oh right, the relay is a good right yeah. We want the relayed. Oh yeah, okay, okay, oh man, I told you this is hard to take out so theoretically, this turns on yeah drops to 15 degrees and then the relay and what stops it? Really? Okay, all right! It'S on! Okay, the temperatures are up and real fast now, so we just went past 15 degrees, Oh yep, and the thing the thing hit turned off. Oh, this definitely needs some tuning, though oh yeah, so just auto-tune, if you hold that that was not necessary, jeebus, okay and so the relay doesn't work Alex. I'M not totally sure you just have it configured wrong because our oh it is this thing. The negative temperatures seems like no fun. It was great so because the relay now serves absolutely no purpose. We don't have to deal with its limitation when it comes to reading negative temperature values, check it out. The old, yellow and gray multi logger thermometer makes an appearance. It'S back from the dead baby, okay, so CPU temps are dropping, dropping we're at 15, 11. 4 3 on the tack. So we need to hit this thing with a load because we had idle like this is such cooling overkill, but it is ridiculous, like we can't. We can't keep turning it on and off like this all the time so which one classroom I'm gonna, maybe BMW. What'S the speed out right now? Okay, look! Stop yeah, okay, so BMW CPU! Here we go! Okay! Here we go. Cpu 10s are up in the 50 60 70 s get that tech turned on baby. Oh yeah, it's on. Can you overwhelm it already? Oh yeah, it's just 34 35 rattling degrees come on. There'S no way that we did all of this ports just crap out like that. Oh we're crawling were throttling. We throttled son, we overwhelmed the tech, okay hold on a second. Let'S stop that stop the blender! Stop the fire wait hold on stop escape yeah, and now it's dropping like from 40. It'S dropping fast, Alex insisted. We get our hands on a variable voltage power supply, so here's a 15 to 24 volt power supply. Let'S fire this thing up and you need to be more excited. This is we're doing work, we're testing it. It'S gonna work, it's gonna be great. I don't actually believe what I just said: okay testing. Oh, it's going up going up fast, but I can turn up the voltage now. Wobb wobb wobb wobb wobb wobb, we're at 330 watts, now 380 watts how's your temperatures there we're at 22 volts we're at 373 watts. How we do is going up fast there. I actually didn't bother. Okay, I'm just gonna stop this test great hold on we're at 24, volts 744 watts. I would probably keep the test on. We are dropping temperature quickly. Here we are at 22. We are 21 we're at 20 degrees, 19 degrees of the feet on the block here, whoa that copper is hot. Okay, I'm sweating right now, yeah the pumps running holy crap, all right, we're at 900 watts on this thing, all right, we're

4. already up to 90 degrees. On the CPUs up, if we're doing 90 watts on the tele 900 we're doing down underwater yeah, we're at 105 degrees that coppers the end of hot somethin smells like burning. We got to turn this off. Okay, if we're drawing like 900 watts - and it still is thermal throttling - there's no way Tech's are ever going to cool at 7,900, I told you yeah so in a nutshell, tech cooling is and was a bad idea and everything that I told you in your first Week here was true: yeah, it's a bad idea and nobody should do it because, even with a super high-powered tech, the power and efficiency, the fact that you need so much more cooling capacity to enough to cool the CPU and all the waste heat off of your Tech, the complexity of the setup and the relays and crap that you need to setup in order to avoid condensation and the fact that you are still going to be limited to like high-end consumer processors at best that you can actually effectively cool with the tech. All these limitations - oh yeah, cost you got go on. I mean that tech cooling is a pretty bad time. There'S no way. We can just finish like this.

So thanks for watching guys sorry, this was such a disappointment to you and Alex oh, like wow. We just totally didn't even have to build this relay box to just find out. It wasn't gonna work, yeah a lot of work hey, but it was a learning experience yeah about listening to your boss next time. What
