- 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😊
Nice video great information without exploding music and wild graphics Thanks !
Really good information for feature projects. Thanks for sharing! :D
thank you for the comparison. i was planning to use one for a power source project. 👍
Incredibly helpful video, i've bought some 12703 modules for a project I want to work on.
Thank you for the test!!! I am trying to make a chilled mirror dewpoint sensor!
I appreciate your hard work. A very informative and helpful video!
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.

Thank you soo much , your work made my project very easy❤🎉❤
Great video! Just what I was looking for!
Thank you for this video. It helped me decide what module to use.. ❤❤❤
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.
This man is creating a whole snow mountain but it is very useful thank you bro❤❤❤❤❤🎉🎉🎉🎉🎉
Thank you so much!!!
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!!
Oh my god, you are really a good man, please carry on, thanks
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
This is a very good share, thanks man.
Thanks bro, this was very useful
Good to know!! Thank you it helpful!!😊🙏🥰🥰
Amazing! I've thought of upgrading a small mini fridge i have, wanna try fan first then maybe a new module. Thanks!
Good job 👍🏽 Thanks for the information
Thankyou, very informative ❤
Cool. Literally. (and... I changed my mind about ordering the 06).
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.
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
Thanks bro for this important video😘😘
Thanks a lot glad I watched this
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
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
Uma ótima comparação, parabéns pelo conteúdo
what happens after 12 hours
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.
Thanks 👍🏻🙏🏻🙏🏻🙏🏻 very informative and technical video
Awesome comparison, now I know why 12703 cost more than double...
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
Great stuff!
It is great for aquarium cooling ! Every new summer temperature are going higher and higher . Thank you
Really good information thanks brother I like it
sorine imi place mult e faci si mult succes
tnx for the info ❤❤
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 researh done!
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!
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?
Thank for sharing
Ooo, esti Roman, m-am abonat instant
Are you planning a cloud chamber Sorin?
Thanks for your information🥰
From Bangladesh
great video love it❤
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
Nice video!👍
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
How does these modules compare under bigger loads
Like cooling of 500ml water
thank you sir
Hi Sorin, Thank you for posting this video. If I were to use a Peltier module in reverse, to apply heat to generate a small amount of electricity, would the 03 module be best choice for being the most efficient, and producing the most electrical energy? Thank you
Hi. I haven't tried it. I think this is a good idea for a future video.
Sir, I really appreciate your hard work and I request you to make a Tesla Coil in your next video, I will be waiting.....
Interesant. Poate in viitor o metoda de a produce energie electrica din aceste module . Eventual atasate pe spatele unei sobe ?
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.
THXYOU
Lots of love ......from India🍃🐣
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.
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.
Beautiful sharing
I think there is new update for our mini fridge video 😁😁. Waiting for it.
Excellent 👍👍👍
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.
Thanks
Excelente amigo😊
Nice video ❤❤ more video
Since nowadays many things are usb powered I wonder if you can do a similar comparison with 5V peltier devices
Yes, I will probably test them in a future video.
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.
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.
Please try some taste with SR-4902 thermoelectric element , can we use this as mobile cooling system
good job
Please try some test with SR-4902 or TES1 -07125 23x23mm thermoelectric element , can we use this as mobile cooling system
Sir I am interested if the peltier can work continuously for 3 hours without burning
Yes, with proper cooling on the hot side.
Great video, is it possible to add a 12702 peltier module in your twst? Thanks.
Thanks! I will make a second video testing Peltier modules, but I will focus on more powerful modules.
nice video
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.
Please try some taste with SR-4902 thermoelectric element , can we use this as mobile cooling system 5:07
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.
That 03 module is as cold as my freezer, fain
Can you make induction heater example on a next video, maybe something to boil water to prepare tea or coffee on the workshop :D
Can it be possible to have a bigger size of a radiator so it can produce bigger ice ?
Hi, I was wondering where you got the ice from even though you didn't use any water? Was it the thermal paste that developed the ice?
Hi, moisture in the air turns to water on the cold surface, then to ice.
@@Sorin_DIY Thank you, this is very helpful.
Hi sir, if we use that peltier module alone without heat sink and fan, module can be damaged?
Yes, it will burn.
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 :)
Hi. Tell me, what type of Peltier do I use for a "Philips perfect draft" machine? Thanks. David.
Hello. I didn't work on this unit, but I found on internet that it has a 70W peltier element and the similar cheap alternative is the 12708. But in my opinion you should buy the 12703 and 12706 modules as well and test which one works better. they are cheap.
actually the results will depend on cooling of hotter side, So next time do it with larger heat sink or with water cooling.
Which SMPS you r using sir
I have Peltier module TECH1-12706 DC I need out put heat so plz how Many volt and ampere have to give thx
Bro im making a mini ac with 4 peltiers of 12v 6amper i have a SMPS of 20A
My question is. Should i use one yellow wire and one black wire from SMPS for all 4 or i should use connection separately for each peltier?
It depends on the thickness of the wires. I suggest you use separate wires for each module, or use a 2.5mm2 wire for all of them.
In those peltier modules, can you test how long it can turn 100L of water to 0⁰C? and power usage.
Would it be better than using a ref. Compressor?
Thank you
Peltier modules are very inefficient. They are good only for small devices or hobby. you should use a refrigerator compressor system.
Teşekkür
why my 703 not like that only 2degree how could you do that -19degree on 703?
Long time Sorin...
Is it possible to run it for some minutes without the active cooling? Can I use a powerbank to run the peltier? How can I calculate how long my 2000mAh would last with the 03 peltier?
You cannot use the Peltier module without a heatsink, it will heat up in a few seconds. using a 5V power bank will have a low efficiency, you should make a battery pack and connect it directly to the Peltier module.
@@Sorin_DIY how big would that battery pack be? I am a total beginner somehow... is that batterypack portable... listen: I want somehow a way to cool down my shoes ... I know I know.. but I have a gen defect that gives me blisters in summer if it is too hot...
