This Cooler DRAWS 545W!!? Bad Cooling Ideas #2

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 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 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 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 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 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 do you need a beautiful website without all the hassle well Squarespace has got you
