- Hello, my friends!
I received a lot of questions about Peltier modules, especially about the TEC1-12706 type, which is actually the least efficient.
But which is the best one? In this episode I will test a few Peltier modules to find out.
A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.

That was fascinating, many thx for sharing and I’m pleased to see your assistant is still working hard keeping those tricky capacitors off the table 😀👍
Not at all😊
What you're seeing is the effect of joule heating. Basically you were able to manage the hot side of smaller peltiers better because heatsinks were larger in proportion.
06 is not rubbish. It has to be planned & executed properly.
Thank you - it would have been nice to see how warm the large heat sync was getting. Liquid cooling would have significantly improved this test.
@@RCToys09 I guess there's a reason why the manufacturer make different types with different price or costing. I bet it not only related with size but also with quality. Using liquid cooling required more electricity as input. So if using same input give different output then we can conclude which is more efficient.
thats it, there was just so much not even considered here, mostly heatsinks...
cold side temp means nothing without hot side too.
lol, heat blocks dont appreciate frozen water. go all bulgy :)
i had to see what it would do with no pump.
do you know what the best peltier model is
Thanks for taking the time to explain to us the difference. I am pretty sure that the 4-5-6 didn't perform as well as the 3, only because it didn't reach the appropriate amp. to perform 100%. On the other hand, to get -20C with only 38 Watts of energy is fantastic! Exactly what I am looking for. Thanks
How do you get it to reach the appropriate amperage? My Peltier chips always run at around 3 amps - far lower than their rated amperage. I have been wondering about this.
yes. each module operates in a different sweet spot. more extensive testing needed
@@FHDesert It does reach the maximum amp. but his cooler is not good enough to remove 72W plus the amount of heat energy from the little cold Radiator. So the hot side gets hotter as it should. That follows that the cold side doesnt get as cold as when he used the 12703
Nice video great information without exploding music and wild graphics Thanks !
thank you for the comparison. i was planning to use one for a power source project. 👍
Really good information for feature projects. Thanks for sharing! :D
Best video about TEC!! Saved me A LOT OF math and guess work!! Thank you sir!!!
This man is creating a whole snow mountain but it is very useful thank you bro❤❤❤❤❤🎉🎉🎉🎉🎉
I appreciate your hard work. A very informative and helpful video!
Great video, but I have Concerns.
Later on, you chose the TEC-12703 because it cools down to the lowest temperature. In the mini-fridge you've build, the Amount of heat the Peltier has to remove is much higher, and the Qc of the 12703 is very low. Dont you think the 12706 does a better job when the amount of heat that has to be removed is quite high?
Thanks! TEC1-12706 may be a little better in a closed box, but it draws more current and it needs a bigger heatsink, so the entire cooler will be bigger, more expensive and will draw more energy.
I will make a more detailed Peltier test video soon, with more powerful peltier modules, bigger heatsink and different voltages.
@@Sorin_DIY I'll enjoy your new video :) I hope you're maybe cooling a liquid or gas with the different peltier Modules, so that we can see how much heat energy is removed through the TEC's. Looking forward to it :)
Repeat the test and track the temp of the large heat sync. You will find that the large heat sync can't keep up with the heat generated by the larger peltier, and it will be hotter with the 12705 than with the 12703. This explains why the temp was greater at 60 minutes than at 30 minutes - the ambient temp of the heat sync rose. A peltier is designed to create a thermal difference between the hot and cold side of the peltier. The colder the hot side is, the colder the cold side will be. For air cooling, the 12703 is better. With liquid cooling, the 12705 will remove more heat than the 12703.
Thank you for the test!!! I am trying to make a chilled mirror dewpoint sensor!
Good to know!! Thank you it helpful!!😊🙏🥰🥰
Thanks for the great video with detailed comparisons. I am making a small (5l) 12v cooler/chiller for my motorcycle trips as I could not find anything remotely suitable. As I am looking to have a compact design within the wall of the cooler, your video has reminded me that I need to allow for condensation dripping off cooled element.
I think you ar romanian so Salut! Chiar imi doream în ultimul timp sa realizez un proiect cu aceste module, iar videoclipul tău ma ajutat enorm!Mulțumesc!!
Great video! Just what I was looking for!
Incredibly helpful video, i've bought some 12703 modules for a project I want to work on.
Finally a comparison review worth watching, hope you can come up with same videos focusing on possible effecient products/model against each other. Keep it Up! Thank you.
Great info and not boring at all to those interested in the field and info
Thanks for the vid and info will help me for sure
Thanks for this beautiful video 🫴🏼❤️🇵🇰
Please do another video like this one, but in the next video, apply heat & determine which module produces the most electrical power when you use the optimal heating for each module design. From what I see online, the TEC1-12706 can produce 57W at 50C, which is 1.425W/mm2. That means ~702 of the TEGs could produce 1 kW of power with an input heat of 50C
Currently working on making a pretty sick Portable AC using these chips. Alot of design is going into it these chips are amazing especially when used correctly.
I'm doing something similar! But with a pillow. How many are you using, you'd need a lot to make any sort of difference even in a tiny personal fan. And you'd have to vent the heat elsewhere or else the net difference is just heating up the room! I'd be interested in seeing your creation.
Thank you, I wouldn't even consider different types without seeing this video
Your speaker video is still the best on youtube that I could find.
If you would build a ribbon type (or rubanoide) speaker that would be crazy.
Test is very good, but only for this size of radiator. If u get bigger radiator with better cooling , u get better results on more power peltier module. so this test is only for this small radiator on hot side.😊
Quite similar as to what I was thinking. Smallest-size peltier (12704) performed "best" compared to the group because of its smallest physical size in proportion to the (heat) radiator. Increasing the cooling capacity (ie: Larger radiator or more fan cooling) in proportion to wattage output needs to be considered to make a fair comparison.
@@Schrimpieman yeap, thats right ;)
@@Schrimpieman you got it.
Thank you for this video. It helped me decide what module to use.. ❤❤❤
Thank you soo much , your work made my project very easy❤🎉❤
I have been searching for this info from a long time finally I landed into correct place very useful info abt peltier module if I had watched this video early I would have not buy 12706 module.
Are you planning a cloud chamber Sorin?
Oh my god, you are really a good man, please carry on, thanks
Great! Could you please make also tests with TEG Modules to make power from heat? Ive noticed that there a great differences by modules and prices.
+1
Yes I would like to understand the differences in energy generation also maximum temperature each on can handle
Awesome comparison, now I know why 12703 cost more than double...
This is a very good share, thanks man.
Thank you very much beatiful video best Science ❤❤❤❤❤❤
It is great for aquarium cooling ! Every new summer temperature are going higher and higher . Thank you
Very helpful! Thanks a lot!
Thank you for the useful content 👍👍
crazy and almost magical technology I was unaware of until lately. I would be curious about this same experiment with numbers on the heat side also
Thankyou, very informative ❤
Cool. Literally. (and... I changed my mind about ordering the 06).
excellent information that was what I was looking for to know what power each peltier plate has. I bought 127015 and it consumes a lot of current and the temperature drops. if your information is correct I go Buy peltier 12703
Thanks bro for this important video😘😘
Thanks for fantastic tutorial👌❤️
Excellent video straight to point...❤❤❤❤❤
Sir, I really appreciate your hard work and I request you to make a Tesla Coil in your next video, I will be waiting.....
Ooo, esti Roman, m-am abonat instant
Good work bro🤜
Can you test all 4 as thermoelectric Generator?
The ones he tested are TEC modules. What you want to see are TEG modules. One creates heat/cold and the other electricity - TEC can be used for both purposes, but probably not with the same result.
Super! Thank you very much!
The TEC1-12706 needs a bigger cooler then TEC1-12703, with the correct cooling the 12706 can reach quickly to -18 - 20 Celsius.
What if u add the bigger cooler to the 03 module?
It could reach -40 even
Lots of love ......from India🍃🐣
Thanks bro, this was very useful
How does these modules compare under bigger loads
Like cooling of 500ml water
Thanks a lot glad I watched this
The modules have different electrical specs and they're being driven with a fixed voltage, the ideal way of driving a peltier module is using a constant current (CC), as resistance varies with temperature. Idealy the module should be driven within 60-70% of its maximum current to maximize lifespan. The last digit of the modules indicates their maximum current. The TEC1-12703 has a maximum current of 3A and is being driven a little above its maximum current. So, this module is being overdriven.
My suggestion would be to compare them using CC at the same percentage of the maximum current of the module being tested.
Thanks for the suggestion. I bought some new Peltier modules and I will test them in a future video.
Amazing! I've thought of upgrading a small mini fridge i have, wanna try fan first then maybe a new module. Thanks!
Hii, nice video sir ❤ can you make this topic on 5v Peltier module from 3 Amps to 1 Amps ? Please sir 🙏
Thanks 👍🏻🙏🏻🙏🏻🙏🏻 very informative and technical video
Uma ótima comparação, parabéns pelo conteúdo
I was planning on making a peltier water cooler, I planted on using some 12706 modules I already had, but I think I'll get some 03 ones instead. Thanks for uploading!
sorine imi place mult e faci si mult succes
Thanks for sharing.
I think there is new update for our mini fridge video 😁😁. Waiting for it.
I built an ice chest air conditioner. At bottom of cooler is ice cold water and a bed of 20lbs of ice Sitting on a wire frame. Just over the ice layer is an internal lid effectively separating the ice chamber from the air intake chamber. 2 radiators ; one is for intake air the other is for the precooled air blower fan. My question requires your expert peltier knowledge. Cam I usea few peltiers to create a mini freezer keep ice colder longer or make circulating water even colder with salt? I'm concerned about cooling the hot side without heating my ice water. Thank you for your channel and all you do to help us
Hi. my next video is a project with Peltier modules, it will clear a lot of things about your project. I will upload it in a few days.
Nice researh done!
Useful test.
Great stuff!
Thanks for your information🥰
From Bangladesh
Really good information thanks brother I like it
Nice, salamat bro
Very amazing ❤
Thank you so much!!!
great video love it❤
You tested the modules on the same heat sink for the hot side!! Tec1 12706 modules require bigger heat sinks to dissipate more more power and so that the hot side doesn't get too hot. It is because the 12706 module has the highest temperature on the hot side that the cold side is lower than the rest peltier modules tend to want to maintain constant temperature difference on a particular electrical power input if the hot side is too hot the cold side will not be cold enough
Hi. I recently made another Peltier test video [test 2], please watch it, because I explained all this.
Thank for sharing
Nice video!👍
Thank You. Please do test for 27 & 19 series. 27145 and 19906
tnx for the info ❤❤
3:18 as the condensation forms it changes phase so heat is added to the system. This is the opposite of sweating.
Hey I have a request for you test the Peltier modules as a generator... apply hot and cold to each side, and see what kind of output the module produces. What happens if you put 20C on cold side and 30C on hot side? What kind of voltage and current is produced?
That 03 module is as cold as my freezer, fain
i think you need to supply 12v 6amps for the 12706 module, for its full load to work.
it wont draw 6 amps at 12v, it needs 14v or higher.
another reason It might do better after 30 minutes than 60 is the ice forming on the cold sidn acting as an inulator, not allowing for thermal transfer
Interesant. Poate in viitor o metoda de a produce energie electrica din aceste module . Eventual atasate pe spatele unei sobe ?
Thanks 🙏 ❤❤❤❤❤❤❤❤❤
Nice video and analysis. Could you please suggest best PELTIER module for heating application? Thanks in advance
Hi. I haven't tested Peltier modules in heating applications, maybe in a future video.
Least efficient at cooling would likely be best for heating. Peltiers move heat from one side to the other but in doing so they convert a lot of the input electricity to heat which goes out the hot side. In other words they put a lot more energy out the hot side than they take in the cold side.
actually the problem with TECs are the larger current you run them at the more cooling they can do but the more heat they produce
so it is quite likely the reason 12706s are underperforming is due to inadequate cooling.
It might be more of a fair test to run them at the same current rather than voltage, iirc peltiers are mostly current affected.
Hi, I recently posted another Peltier test video with a better cooler, you can check the results.
muchas gracias por la info
Excellent 👍👍👍
Beautiful sharing
thank you sir
Which would be better for generating electricity from a heat source? Does the efficiency work in both directions?
I haven't tested them in this way. I will try in a future video.
now i know what the number means thank you
Excelente amigo😊
Moral of this that isn't shown in the video: The Less load you have, the smaller peltier is more efficient always. If you have a heavier load that makes the module stay at a warmer temperature the entire time (Say water cooling something) you want a larger module to pull more heat at a given time. Same thing happens with a Portable cooler fridge.
This is why water cooling something on the cold side is alot better of a load than a heat sink most of the time because the water will add it's heat energy to the cold side 25 times faster than air.
However sometimes water cooling the hot side is the only water cooling that's needed to get better efficiency out of the correct size module.
The Smaller the volume, the smaller your module should be for efficiency. If its 1 Cubic foot of volume however, you'll want about a 10 Amp rated module instead so that the module can remove more heat at a given time. If the module stays cold on the cold side the entire time, your not fully utilizing the cooling capacity of the peltier unit and are just wasting energy. So always test to make sure it's enough power to get to your target temp, and keep going smaller until it's no longer enough cooling capacity then you'll know what is the best current rating for your project.
excelent analysis bro🎉
i am a newbie😢 tryin to build diy air cooler for home
which module and amps u suggest
and u recomend both sides water cooled or
Thank you, let's talk about your thermal load. How much room in Cubic feet are you trying to cool? A Thermoelectric system on a large scale wouldn't be very efficient. But that's not going to stop me from giving you the numbers your looking for. With a load as large as this, and for the CFM needed, yes its mandatory to have both sides water cooled.@@coolmonkey5269
Thankyou thankyou thankyou❤
Very informative video. Thanks for sharing. Do you mind revealing what thermal paste you used? I am finding in my own testing that this is making a big difference in temperatures I am measuring on the cold side. I changed thermal paste on a peltier/heatsink module that I had purchased and the temperature I was measuring was at least 7 degrees C warmer than it was before the paste change.
Hi. In this video I used a medium quality thermal paste from aliexpress. With better quality/more expensive thermal paste I would probably get better results.
5:07 Is there an error? The chart shows the 12703 Takes 3.18AMP but in the background the PSU shows 3.27AMP
Hi. There is no error. the cooling fan also draws 0.09A from the power supply, so the total fan+peltier consumption is 3.27A
Oh! I gotta recalculate some stuff then! Thank you! I bought 20x of these Peltier modules you posted@@Sorin_DIY
I would be glad if you could make a test of temperature drop in a space of 1 cubic feet for example.
I made a Peltier cooler box, you can check out that project and use it as a reference.
Nice video ❤❤ more video
I have reached -27/28° C after some minute with 12706 peltier on a cooler master hyper h412r heatsink, with 7 amps of current at 15 volt
