The TECs did not draw the full amount of power expected because the supply voltage was too low. Looking at the data sheet for TEC1-12710, these modules will need up to 17V, but the supply used was only 12V.

"Engineering". Michael Reeves is more of an engineer than Alex is. So is Electroboom, Adam Savage, Simone Giertz, Integza, Joel Creates... heck, even Dan, on this very channel, is a better engineer.
His video ideas are the most interesting thing on the channel for sure. I'd be way more into the boring "we bought a mansion" videos if Alex was doing all the HVAC.
I spent a couple of years playing with TEC's, successfully building out a universal whole case cooler that dropped the CPU temp by 20c while maintaining a case temp of around 10c. So a few things, mounting pressure on the TEC plate is EXTREMELY important, you need even pressure across both sides or performance takes a serious hit. We ended up threading out own bolts with a very high thread density, counting the turns and confirming with calipers. You also need to have a neoprene gasket (cut a hole for the TEC and sandwich between the heatsinks) we used quarter inch high density neoprene, but your application may need something different. We also used 600w TEC's (24v @ 25a) which required a special switching PSU (30v@30a), and HUGE melcor nickle plated copper heatsinks that were cooled with 120mm 120cfm sillverstone fans. The HS's were 120x120x90mm, and each weighed about 5 pounds, with each tec using TWO. You can simply drop the cold side into a container of water, and use as many as you like. The other important thing, you're much better off using high power TEC's like the 600w we used, and undervolting it. At lower power, TEC plates are much more efficient. Basically you're better off using 8 600w TEC plates, running 75w each than you are using 1 plate running full load. I would have to check my 15 year old forum posts, but i'm pretty sure we found that 30% load was the sweet spot in terms of efficiency, though i'm really not sure if that's a flat metric or simply applied to our 600w plates. Either way, i'd suggest taking another run at this, you should be able to get much better results using much fewer parts and a less janky set up.
@@heygek2769 I'm sure it is, but they've taken a couple runs at TEC coolers for various applications, and in each instance they've done it rather poorly, ended up with bad, or at least insanely inefficient results, and perpetuate the idea that TEC's are useless. I freely admit, this is a personal pet peeve and this was clearly done for the entertainment value, but...if you're going to do something, you really should try to do it as well as you possibly can. One of the simplest things that is consistently overlooked, is using a TEC to cool the back of your CPU socket. There have actually been a few cases in recent years that have employed fans behind the motherboard tray for this purpose, using a TEC in this was is simply more beneficial, and less complicated than trying to directly cool the chip. Like i said before, i spent years playing around with TEC designs, and ended up with several very viable solutions that i simply didn't have the money to see through, and now i just don't have the time. These guys do, and i'd like to see them make a serious attempt.
Alex, Jake & Dan are perfect trio. Alex "should be fine" frankenstein inventions are lawful evil. Jake's persona is chaotic good. & Dan is the true neutral with pinpoint accuracy reactions. I can't imagine the LTT/LMG without them.
I think the whole bubble trapping thing could've been solved if they mounted each row in series and not all of them in parallel but i still love the idea!
Alex, the way you connected the pumps is not giving you double the head pressure, you are basically connecting them in tandem. This mean that one pump discharges just to feed the suction tank to the next. There is not pressure transmission doing that, so basically is just the last pump working, the first is just feeding the second tank, that’s it. If you want to connect the pumps in series to double the head pressure you need to connect directly the discharge side of pump 1 to the inlet side of pump 2. If you want to double the flow, then both pumps must be connected to a discharge pipe at the same time, but the total head is equivalent to one pump.
that WOULD be really cool to see if it could ever be really good at what it's supposed to do... but on the flip side, "optimized and efficient" isn't really the reason we click on these videos, is it? xD
There is a channel called "Этот Компьютер", in his playlists there is a playlist called "Пельтье", there he assembled his cooling system on peltier modules with a solution to the problems that Alex encountered(these videos are two years old)
Indeed. I remember his first videos... he was paired with Riley and I believe Anthony also had some videos here and there. They both sucked. Riley was always a natural. I bet he cheated. But now Alex has found his own style and it''s fantastic.
Still waiting for a video where they do sub-ambient cooling without electrical worries, by sealing the whole PC in a different atmosphere without water in it. Someone needs to do it!
I believe you ran the cooling to the peltiers in parallel, that would completely explain why the coolant was not getting there. Water always takes the easiest route so there was no need for it to go through the top ones, it could just go through the bottom ones. Also rethink the diameter or your water tubes, the tubes going to the waterblocks were really thick and the one going to the pumps was only a little thicker. No wonder there was almost no flow in some areas. You would probably be fine with those flimsy 5mm ish tubes going to the individual units on the hot side. Maybe for a second iteration of this split the cooling system up into groups of like 4 peltiers cooled in series with smaller separate radiators. Also have the water in the cold loop flow the other direction from that in the hot loop to make sure the water doesn't get reheated by the higher temperature peltiers (because they are in series the last one gets a lot warmer cooling water and thus will cool less far on the cold side). I think by hooking up the cold side in groups of 4 (or so) with their own pump and combining the output with a splitter to the CPU plus the aforementioned changes you could optimize this setup.
You need a separate res at the top of the loop for this to work. pump at the bottom, res at the top, then you're not fighting gravity. come on guys this is water loops 101!
also the clamps idea was alright, but you can make mini clamps out of 2 sections of dowel and 2 wood screws. then you can make 1 adjustable clamp for each inlet and dial in the restriction perfectly!
1. Use a few distribution blocks (eg Phoenix PTFIX) instead of soldering 80 wires. Or good old Wagos. You'll hate yourself less. 2. I would do a 5s4p connection instead of 20p to save on tubing effort while having some redundancy. E: any manifold connection has potential for unequal flow so you need to watch out for that. Big benefit of series tubing is you have the same flow rate everywhere.
But that means potentially trying to remove 600W from a small 40mm x 40mm waterblock. I don't think you can get a fast enough flowrate through it to make that happen.
He could tune the flow rates with flow controls. reducing flow in the lower peltier devices would probably balance the flow up to the peltier devices that are much higher and thus need more head pressure. If you are feeding the same head pressure to each row the top will never get good flow.
I feel like in a previous video, it was established that if you want to do this, you should first run the hot water through a radiator to get the temperature down for most of the way and then run it past the TECs to go sub-ambient.
As not an engineer. But knowing something about something. I 3th this Also using different hardware for the distribution would've made it more efficient
these kind of videos are the most interesting you guys put out; just let Alex and the other engineers do whatever crap they come up with, its super entertaining
It’s great that they always happen at the onset of the new generation. Then legit coolers come out, then the next generation changes it up again and the cycle repeats
I've never gotten cracked up by these sentence but when Dan came up to them and said "What the fuck is this abomination?", "What are you cooling?" and "What are you heating with this?" all at the same time I audibly laughed
You gotta connect those blocks on the peltier-s in parallel (at least in blocks). You could do four groups of TEC-s with each group having their own pump and radiator combo so you have higher crossection for the water to flow through. If you connected everything here in series, I would imagine, the pressure needed to push the coolant through the whole system is too much with just a tubes diameter of cross section for coolant flow.
As I understood it, they were connected in two parallel blocks of 10. The frame's left side supported 10 TEC-s, and the right supported the other 10. Front was cold, back was hot. Am I missing something? These aren't connected in series at all.
@@TorgieMadison They all had their own circuit, which makes for a very long pipe in sum. When you group 4, you almost cut that length by /4 -> less pressure is needed.
@@VealCalf1 If you make yourself familiar with these particular physics you will learn that the relation of pressure needed to length of the pipe is not linear. Spreading out the pumps to different positions in the circuit could help with that.
You need a manifold that distributes to each of the lines with a constant volume flow rate. In other words, the fluid is taking the path of least resistance, like the lower TECs and shorter tubing runs.
Thank you Thank you Thank you LTT, 1 wk ago it was so close to buy the 1/10th of your test parts on Aliexpress, still try to convince myself, then you did it for me, saved he heaps effort, and made my mind to keep standard water cooling. thank you again...
Always enjoy mad Alex engineering. You definitely need to revisit this with debauer's delidding tool and whatever tips were on the GN N2 overclocking stream! Also great seeing you guys host this content without Linus. It amazing how everyone has grown their presenting skills over the years!
I SEE IT. He has the engineer eyes now. You know, the sort of sunken, passion deprived gaze that is earned by answering emails and attending team meetings instead of doing ACTUAL work. Congratulations.
I did the same but in smaller dimensions (about 400W). I wasn't happy with the results. So i tried the outdoor mod. Placing my 9x120mm radiator outdoors at about negativ 5 degrees celsius improved the result greatly. The cool side of the peltier element was extremely cooled and the cold side could get insanely cold (not gonna spoiler, try it out its crazy!!!. Its easy to realise If mother nature provides you with the right circumstances. Shouldnt be a problem in Canada i guess. I would love to see you stepping the project up with the "oudoor mod". Sorry for my terrible english and greetings from Austria
For a manifolded assembly like that you want it to be horizontal rather than vertical so gravity affects each one the same. Then you can have radiators attached to the hot side drawing cool air from the cold tubes on the bottom and the cold side blowing chilled air over the hot tubes on top for a small performance boost in the setup.
Hot side in series would only make most of them non-functional as they'd be "cooled" with hot water (heated by earlier ones). OTOH the "cold side" in series would freeze the antifreeze, as the cooling effects would keep stacking.
I'm here for more of Alex's off-the-wall cooling ideas! As in, he comes up with the ideas by "throwing shit at the wall to see what sticks", then makes videos out of what does /not/ stick.
I used to have the "Ultra" brand peltier tower air cooler hybrid. It actually worked very well. With how it was set up it kept the CPU at one temperature when under load, didn't cool it too much or too little. Gimmicky, yeah. But it was cool as hell and still did a fairly good job. Not the best, but good. This idea takes that to the max. I like these ideas lol
I can’t believe you guys are doing ANOTHER peltier cooler video right as I’m designing a stupidly crazy design for a giant observatory telescope chilling system. So thankful!!
Please don't use Alex as a starting point. He is making so many stupid mistakes. Main stupid thing was that he did not place the header tank on the top of the loop.
@@Running_Wakko don’t worry, we aren’t using this is a guide! Our system is going to be far more complex as it has to work in all orientations. The water blocks will be changing orientation as the telescope mirror moves around, so we have to account for everything. We’re gonna build a working model before we even try out the real thing.
Honestly, I love these types of videos, even if the result doesn't exactly pan out! Sometimes you get a wild and crazy result, and we all benefit by learning!
I think my Prometia cooler only drew like 800w and could keep a 500W load at -20C. I just got tired of dealing with condensation, so went with water chiller that keeps the loop at 1C above ambient.
i think you might get better results if you use a large high reservoir above each loop and let the pumps just pump the liquids up, then let gravity let the liquids flow through the coolers this would probably get equal flow through each cooling element. that way you could also store some cold liquid in the reservoir and run a benchmark from the stored cooling capacity of the reservoir.
I think the pumps needed to be split up among the different sets of coolers, so a pump and a "one in five out" manifold per level of that tower. Getting the water/coolant to cycle properly through all the blocks would probably make a huge difference, and if I understand how they work correctly, may actually get the TECs to draw more power. The reason for that being they have temperature limits on the hot side, once it reaches a certain point it just can't push more heat across, and will drop off.
At this point Alex is just living out his wildest cooling dreams. I feel he probably left instructions that, in the event of his death during one of these LTT projects, there will be an engraving "worth it" on his tombstone. In all seriousness though: while we enjoy all the messing around, please stay safe dude!
I really was hoping they'd go all out and like machine a whole water block manifold for the in side and outside. I would love to see a rig they make that actually has some bananas cooling and could be used later on for other experiments. Kinda like their air conditioner cooler.
16:06: I like how they black out the password, like anyone wants to break into their warehouse, ignore all the expensive equipment, and take a motherboard covered in vasoline 🙄
If i was Linus i would be so proud of Alex and his mad ideas. Also he got so much better in front of camera, i'm so happy to see him do this kind of stuff with this confidence. Go Alex!
i think you should try improving this. you should mount the pump/reservoir up high to prevent air lock and pressure issues if you want to keep testing the in parallel like you are. i would recommend each row of coolers in series and then have the rows connected in parallel. it would really force the coolant to circulate through the coolers and likely require less force and make the water much cooler.
Exactly, never understood why most liquid cooling setups in typical computers have the res down lower either, should be the highest point - even higher than the rad - makes it much easier and would automatically deaerate
You should have used the 'Tichelmann-System' for tubing. That's a plumbing/piping technique. This way you would have the same resistance in every loop so the Water would spread properly between all loops.
Don't you have a pretty well-equipped workshop with a CNC? Don't you think making yourself a nice channelplate from a copper (or aluminium) block might have ended up being easier than assembling 40 of this tiny waterblocks? And also probably add less flow-resistance to you water-loop? Also, much less problems with the massive height-differences? Also putting the full voltage on the TECs might not be the bestest Idea, once the hot side loop isn't capable at staying near ambient temperatures anymore, the cold side is still going to give you a temperature difference, but now it's only relative to the luke-warm water on the hot side. And 1400W on the (maybe) 100 l/h you get from a D5 means: 1400W / 4.2 J/g/K / (100 kg / 3600 s) => at least 12K heat-up per cycle, not sure at which temperature your radiators will manage to remove 12K per cycle? By the way, if the TEC is specified to a maximum heat transfer of 120W, than this is the heat it can take from the cool side, at 0K temperature difference. While being operated at maximum specified current, and usually at a very low efficiency. Which means 120W is by no means the maximum of heat it can offer at the hot side, that is more likely to end up between 360W and 600W. So with your 3kW of PSU-power, you wouldn't have been remotely on the safe side if you had given them their maximum voltage. But for a small TEC that want's to move 120W this voltage is probably above 12V anyways, right? All I'm really trying to say: There is a way to build an effective, and reasonably efficient, chiller from 20 TECs with 120W peak capacity each. But there is also a way to just yolo it for a funny video ...
I like how Alex be like "Linus, we are really need all of these several thousands of dollars CNC's" and his actual projects be like "clamps, duct tape and blessings of Gork and Mork ".
The TECs did not draw the full amount of power expected because the supply voltage was too low. Looking at the data sheet for TEC1-12710, these modules will need up to 17V, but the supply used was only 12V.
Makes sense indeed. I was sure something was off. This was it. Thanks for confirming

If you connected everything here in series, I would imagine, the pressure needed to push the coolant through the whole system is too much with just a tubes diameter of cross section for coolant flow.
As I understood it, they were connected in two parallel blocks of 10. The frame's left side supported 10 TEC-s, and the right supported the other 10. Front was cold, back was hot. Am I missing something? These aren't connected in series at all.
@@TorgieMadison They all had their own circuit, which makes for a very long pipe in sum. When you group 4, you almost cut that length by /4 -> less pressure is needed.
I mean, yeah. But if you do that and lay the frame down so that you don't need the pumps to lift the coolant 3 feet it would work a whole lot better.
@@VealCalf1 If you make yourself familiar with these particular physics you will learn that the relation of pressure needed to length of the pipe is not linear. Spreading out the pumps to different positions in the circuit could help with that.
You need a manifold that distributes to each of the lines with a constant volume flow rate. In other words, the fluid is taking the path of least resistance, like the lower TECs and shorter tubing runs.
This is the right answer.
Restrict the lowers, use separate pumps, or series up several of the TECs
just have loops for few tec's each going to a tank and a different loop from the tank to the cpu.
@@lasskinn474 makes more sense
I failed thermofuids 3 times and even I was frustrated he didn't lift the red above the techs
I played too much factorio/satisfactory to know this 🤣
Thank you Thank you Thank you LTT, 1 wk ago it was so close to buy the 1/10th of your test parts on Aliexpress, still try to convince myself, then you did it for me, saved he heaps effort, and made my mind to keep standard water cooling. thank you again...
Jake getting sprayed after asking if he can just crack it real quick had me cackling
Always enjoy mad Alex engineering.
You definitely need to revisit this with debauer's delidding tool and whatever tips were on the GN N2 overclocking stream!
Also great seeing you guys host this content without Linus. It amazing how everyone has grown their presenting skills over the years!
I love how positive Alex’s energy is
He loves cooling of course he's a chill dude
Alex must be having the time of his life because we all know weird ideas pop into our heads but everyone get the chance to implement them.
POV: You have the Linus budget and a crazy idea. But it somehow works at the end.
I SEE IT.
He has the engineer eyes now.
You know, the sort of sunken, passion deprived gaze that is earned by answering emails and attending team meetings instead of doing ACTUAL work.
Congratulations.
Stuff like this is why I'm subscribed. By far my favourite clip from LTT in ages.
Just a pity Linus wasn't there to drop it.
I did the same but in smaller dimensions (about 400W). I wasn't happy with the results. So i tried the outdoor mod. Placing my 9x120mm radiator outdoors at about negativ 5 degrees celsius improved the result greatly. The cool side of the peltier element was extremely cooled and the cold side could get insanely cold (not gonna spoiler, try it out its crazy!!!. Its easy to realise If mother nature provides you with the right circumstances. Shouldnt be a problem in Canada i guess. I would love to see you stepping the project up with the "oudoor mod".
Sorry for my terrible english and greetings from Austria
Austrians and their cooling solutions smh
This was so insane and felt fast-paced, I'm amazed that this video exists
For a manifolded assembly like that you want it to be horizontal rather than vertical so gravity affects each one the same. Then you can have radiators attached to the hot side drawing cool air from the cold tubes on the bottom and the cold side blowing chilled air over the hot tubes on top for a small performance boost in the setup.
Alex is the best learning source of how to do water cooling, by pointing out ALL of the "don't do this" examples. A true master of his own craft.
Alex: Something is not okay with this computer
*Also Alex making Alien stuff just to cool the CPU*
Alex's introduction to tecs and cables has probably taught me more than the 8 years of physics class I had so far
what?
We are slowly getting to a point, where our CPU coolers will need their own coolers.
@Ahmed Jones but If we get a cooler for the CPU cooler's cooler, then we'd also need another cooler for the cooler for the CPU cooler's cooler.
You do know you can get 40x120 aluminum water blocks so you can reduce you hose usage by a factor of nearly 4. J/s Hilarious fun build though! 🤘🏼🤘🏼
You should connect the blocks in series. So you solve the pressure problem and equalize blocks temps.
Agreed. Would've made it really easy to bleed the whole system
Hot side in series would only make most of them non-functional as they'd be "cooled" with hot water (heated by earlier ones). OTOH the "cold side" in series would freeze the antifreeze, as the cooling effects would keep stacking.
@@muffinconsumer4106 Would require a lot of smaller radiators, couldn't use these big liquid cooling radiators they did.
I'm here for more of Alex's off-the-wall cooling ideas! As in, he comes up with the ideas by "throwing shit at the wall to see what sticks", then makes videos out of what does /not/ stick.
I love these engineering videos. Please keep them going in any way you can.
I used to have the "Ultra" brand peltier tower air cooler hybrid. It actually worked very well. With how it was set up it kept the CPU at one temperature when under load, didn't cool it too much or too little.
Gimmicky, yeah. But it was cool as hell and still did a fairly good job. Not the best, but good.
This idea takes that to the max. I like these ideas lol
0:43 oh-oh, watch me **Double-tap**
I can't look away from your cooling ideas, just like you said.
I love them.
Please, keep doing what you do, Alex. It's great entertainment!
I can’t believe you guys are doing ANOTHER peltier cooler video right as I’m designing a stupidly crazy design for a giant observatory telescope chilling system. So thankful!!
Please don't use Alex as a starting point. He is making so many stupid mistakes. Main stupid thing was that he did not place the header tank on the top of the loop.
@@Running_Wakko don’t worry, we aren’t using this is a guide! Our system is going to be far more complex as it has to work in all orientations. The water blocks will be changing orientation as the telescope mirror moves around, so we have to account for everything. We’re gonna build a working model before we even try out the real thing.
Honestly, I love these types of videos, even if the result doesn't exactly pan out! Sometimes you get a wild and crazy result, and we all benefit by learning!
alex is easily my favorite person to see leading a project
Every time Alex says something to the lengths of "It's fine." / "It's gonna be fine." / "It should be fine." I know it's going to be a good video.
This was great, we need more Alex and Jake making amazing jank
This is absolutely insane and im so glad you guys made it. 9:21 best part
These guys could never be plumpers! Or anything else than RUclipsrs! 😏
I think my Prometia cooler only drew like 800w and could keep a 500W load at -20C. I just got tired of dealing with condensation, so went with water chiller that keeps the loop at 1C above ambient.
love alex's strange, wierd and amazing cooling ideas! best one yet!
This whole video feels like 2 kids got left unsupervised with dad's tools over a school holiday. I love it
Okay this is way cooler than I was expecting. You need a better thumbnail.
Alex, Jake and AliExpress in one Video.
And its exactly as insane as expected!
i think you might get better results if you use a large high reservoir above each loop and let the pumps just pump the liquids up, then let gravity let the liquids flow through the coolers this would probably get equal flow through each cooling element.
that way you could also store some cold liquid in the reservoir and run a benchmark from the stored cooling capacity of the reservoir.
I think the pumps needed to be split up among the different sets of coolers, so a pump and a "one in five out" manifold per level of that tower. Getting the water/coolant to cycle properly through all the blocks would probably make a huge difference, and if I understand how they work correctly, may actually get the TECs to draw more power. The reason for that being they have temperature limits on the hot side, once it reaches a certain point it just can't push more heat across, and will drop off.
Those tecs need 17v, they were giving them 12v. So the devices were underpowered, thus under delivering.
I keep coming back to alex's videos. They are always so full of controlled chaos that they are the most fun videos of this channel.
At this point Alex is just living out his wildest cooling dreams. I feel he probably left instructions that, in the event of his death during one of these LTT projects, there will be an engraving "worth it" on his tombstone. In all seriousness though: while we enjoy all the messing around, please stay safe dude!
Should have had those tec modules in series and parallel behind each other cooling the hot side of the other tecs for a multi-stage
Exposed wiring, lots of water everywhere. Loving it.
Alex and Jake are a funny team doing Frankensteiny stuff. More please!
Me: "Man this headache sucks, I hope it doesn't get worse"
My head: 9:43
I love this idea. Also Dan coming in was gold.
Alex is the mad scientist of LMG 😂
I really was hoping they'd go all out and like machine a whole water block manifold for the in side and outside. I would love to see a rig they make that actually has some bananas cooling and could be used later on for other experiments. Kinda like their air conditioner cooler.
16:06: I like how they black out the password, like anyone wants to break into their warehouse, ignore all the expensive equipment, and take a motherboard covered in vasoline 🙄
If i was Linus i would be so proud of Alex and his mad ideas.
Also he got so much better in front of camera, i'm so happy to see him do this kind of stuff with this confidence.
Go Alex!
Man, Alex literally has the best job. He gets to build outrageous concoctions, for fun, at the cost of his employer lol.
i think you should try improving this. you should mount the pump/reservoir up high to prevent air lock and pressure issues if you want to keep testing the in parallel like you are. i would recommend each row of coolers in series and then have the rows connected in parallel. it would really force the coolant to circulate through the coolers and likely require less force and make the water much cooler.
actually u just write my toughts 😅😅😅
Exactly, never understood why most liquid cooling setups in typical computers have the res down lower either, should be the highest point - even higher than the rad - makes it much easier and would automatically deaerate
Bloody fantastic! Alex has the best and craziest idea's, the things we have all thought of doing but would never do, But he pulls them off. Love it
Peak Alex. Best addition to the team. Been watching since the days of just Linus and luke and having Alex onboard feels like a breath of fresh air.
the amount of chaos in this video is incredible. Im down for more alex and jake videos like this haha
Best combo, Alex‘s wacky builds an Jakes jokes and ideas go a long way for great entertainment!
Alex, Jake and Dan doing mad science cooling. Love it!
I think with the new AMD cpu and Nvidia gpu all the time the user will be thinking about the Electricity bill
'Borrowing' from a friend.
then again, you wouldn't need heating at all during winter, so the expenses might cancel out
Only time I've used a peltier was for a DIY dehumidifier, they're terribly ineficient, just don't use them.
this channel has gotten me through some hard times and every time I hear the intro song I smile
You should have used the 'Tichelmann-System' for tubing. That's a plumbing/piping technique.
This way you would have the same resistance in every loop so the Water would spread properly between all loops.
@Steve King hm?
9:26 I bet Lulu wants a taste then
Don't you have a pretty well-equipped workshop with a CNC? Don't you think making yourself a nice channelplate from a copper (or aluminium) block might have ended up being easier than assembling 40 of this tiny waterblocks? And also probably add less flow-resistance to you water-loop? Also, much less problems with the massive height-differences?
Also putting the full voltage on the TECs might not be the bestest Idea, once the hot side loop isn't capable at staying near ambient temperatures anymore, the cold side is still going to give you a temperature difference, but now it's only relative to the luke-warm water on the hot side. And 1400W on the (maybe) 100 l/h you get from a D5 means: 1400W / 4.2 J/g/K / (100 kg / 3600 s) => at least 12K heat-up per cycle, not sure at which temperature your radiators will manage to remove 12K per cycle?
By the way, if the TEC is specified to a maximum heat transfer of 120W, than this is the heat it can take from the cool side, at 0K temperature difference. While being operated at maximum specified current, and usually at a very low efficiency. Which means 120W is by no means the maximum of heat it can offer at the hot side, that is more likely to end up between 360W and 600W. So with your 3kW of PSU-power, you wouldn't have been remotely on the safe side if you had given them their maximum voltage. But for a small TEC that want's to move 120W this voltage is probably above 12V anyways, right?
All I'm really trying to say: There is a way to build an effective, and reasonably efficient, chiller from 20 TECs with 120W peak capacity each. But there is also a way to just yolo it for a funny video ...
I was thinking the same thing
I like how Alex be like "Linus, we are really need all of these several thousands of dollars CNC's" and his actual projects be like "clamps, duct tape and blessings of Gork and Mork ".
12:30, just as i zone out from whatever the point was for this very entertaining & funny mess
Jeez, & I thought the RTX 4090 was a power guzzler.
