You didn't miss a thing that 90% of the makers do: Make something not only functional but also neat. Great job.
I clicked the like button the moment you applied the thermal paste correctly.
Pretty cool science fair project, will have to save this for when i have kids, definitely a fun way to use some old CPU coolers
Nice work. Well executed. Even criticisms from super-nerds are helpful in machines like this because one can't think of everything.
this is really well produced. well done mate
finally, someone else using these beasts. I thought I was the only one
At first i was like where the hell is he gonna put the cpu.
i once tested a setup similar to this on a Athlon 2 core and was disappointed
@@johndoe-rd6jn for cooling something like a cpu you need atleast twice the cooling area as you would need for a normal air cooler because you are cooling under room temperature usually and its not terribly efficient
@@johndoe-rd6jn Get a better peltier.
Definitely building this for my PC. It's always running hot. Like 75C +
Back in the day, it was a CPU, adapter plate (copper or aluminum), Peltier, Water block (copper), surgical tubing, transmission cooler, fans of course, and viola... sub freezing temps all day, distilled ice all over the cpu and sometimes board, and all the overclocking of a FCPGA 370 celeron, PIII, etc that one could want. This dates back to say the P233MMX or so as well, and anything in between. This was in the days of Overclockershideout.com, which I think still exists, but likely isn't what it was. What it was, was overclock databases, a marketplace where machinists, creative types, etc to sell and exchange their wares. Was where I sourced the tank, pump, and tubing for my cooling system. A bench-top power supply drove the peltier and fans, with a separate case with various wired together ATX PSU's doing the entire job of computer and cooling prev to that. Those were the days... Pushing a Celery to beat the newest and best PII or PIII numbers. Pushing your RIVA 128, Voodoo Banshee, V2, V3, V5, etc all the farther it could be pushed... Playing games when games were breaking boundaries and rules the same way you were in the convention of PC building. I miss the good ol days
Yea, that's some really old school overclocking there! I had some of that hardware but never oc'd it like that. So what did you get in DooM? Like an extra 5 FPS? I upgraded my whole computer so I could play that damn game. ;-) Cheers!
@@krissebesta Depending on the era, it was any number of crazy combinations. Though once I mastered the original socket 370 platform, I then found the Abit BP6, dual socket 370 board. This was right around the advent of Win2k, so there was the OS that would bridge the gap between mainstream use, and NT level support for multiple CPU's. As back then, there were no "multicore" anything, no hyperthreading... just one cpu, one core. But I had two, lol... both with direct peltier cooling, then water cooled... for wonderful ice and overclocks. This was an incredible era because chips were topping out via intel or AMD at clock rates under 1Ghz... a Ghz wasn't even a term yet... we were at maybe 500Mhz on PII's at that point... and I was pushing two Celerons from 433 to about 800, and just destroying everything else made. It then went to an Abit VP6 with two similarly cooled and pushed FCPGA Celerons. Then the same board with two 933Mhz PIII's the Coppermine FCPGA obviously... pushed well beyond 1.2Ghz before they were officially even breaking the barrier. And it was such an ALIVE scene. Pushing these boundaries and seeing the very tangible results.. believe me, it was far more than 5fps increases, lol... we are talking about exponentially more power than any originally conceived mainstream machine back then, more than servers and the most power house of top end rigs... This was experimental, unconventional... with multiple CPU cores working on calculations in a time where this just wasn't even a thing... plus the massive overclocks on each of them :) . It was a very rewarding time to be involved in the game, where as today it is more or less just... turn key. You buy an unlocked cpu, meant to be selectively and easily "overclocked" from the factory... with a warranty that even allows for this. Back then overclocking was pushing things beyond that of their design, not buying a kit that makes it the most simplistic and easiest process imaginable. It was a talent, a skill, and something that took considerable commitment. Was fun... then it all sort of dissolved into this mainstream blah of today.
Do you have any info about the actual cooling power you get out of this thing? For example how long does it take to cool 1L of water by 1°C? Also, what power are the Peltier elements rated? Thanks!
just a fyi.. That aluminum tape was a bad idea since you are transferring heat to the cold side that way thus killing efficiency a bit...and the proper placement of components will also help quite a bit as mentioned below (hot sides upwards etc. ).
Im waiting on some parts from china to do something similar BUT that cold water you have as a result will have a submerged 12v pump that will feed a 240mm radiator with 4 fans(push pull) blowing cold air into a small bedroom. Like a small a/c unit...
No, not really. The glue on the tape is a crap conductor.
it really doesn't matter how much of heat output you would have on water side - TEC12710 peltier is unable to transport anymore then 93.5W at 12V, anything above that stay where it originates
Sorry for this noob question but.. What is Peltier Water Cooler for? Just to make the liquid icey?
A 100W peltier with perfect thermal transfer (which won't ever happen) is capable of transferring approx 340~ BTU...so not a huge amount of heat transfer capability. So even a cheapish 3000BTU AC is so much more efficient at moving heat from the cold side to the hot side (cold inside, hot outside)
GreekRage also, I was wondering how to mount a peltier to the CPU heatsink. I bought thermal grease but it looks like I need some glue instead.. How would you have mounted it?
Wow I just now found out about these chips! It’s so weird how something like that can get cold just from electricity. I want to build one of these
To maximize your cold output, you need to apply a higher pressure on the peltier/heatsink/waterblock junction. Also insulating the hozes will yield another couple of degrees. Nice project though :-)
Kurt Andersen As Phil Stillwell said, it could also help to orient the heat sinks such that the cooling blocks are on the bottom. I didn't know it but those copper heat pipes are filled with refrigerant.
Yes, it's true but horizontal alignment is also OK. What you really don't want is to mount upside down. Refrigerant agent vaporize with contact of middle section and then condenses in side sections. It transfer heat much faster but this is not the point in this project.
check out Ryans projekt here: www.overclock.net/t/1606680/peltier-tec-hybrid-water-cooling I made a similar setup but with Water cooling the hotside.
I've read somewhere that letting the hot side getting "more hot" will make cold side much colder, some kind of that principle. Has anyone ever tested that by reducing fan speed on the hot side heatsink??
Nice project, some good comments about increasing pressure and removing conductive tape etc. Also better cooling may be achieved by reducing the voltage across the peltiers, My rig using TEC-1-12715 gives best efficiency at 8.5 amps. The most important thing when using peltiers is removing the excess heat from the peltier. The chips generate far more heat than they transfer at higher currents.For example my TEC-1-12715 running at 8.5 amps and 10 volts will transfer about 33 Watts but increasing the current to 11 amps at 14 volts only has a heat transfer of about 28 Watts. The reason is my CPU cooler can work fairly well with 118 Watts (85 W from chip 33 W from heat transfer) but the cooler struggles with 182 W (154 W from chip 28 W from cooling). So I guess I am saying you have to match your operating current to your CPU cooler. Don't just think stronger peltier will give better cooling the heat sink needs improving as well.
I considered doing something similar to this in a PC watercooling setup. getting a high end water block with fine copper channels and attaching it to the peltier to pre-chill the water before it enter's the CPU's waterblock. Allowing the water going to the cpu to be lower than ambient temps.
Thankyou very much for the video i have been thinking about building a cooler for my still so I don't need to use bags of ice to cool the water for the condenser I run the still for 8+ hours at a time I'd definitely need to make a fairly large unit I think something capable of keeping 60l of water below 5° do you think they could handle it or be capable of keeping the water at that temp for extended periods?
This is a cool project! I have some thoughts that you might consider to get a little better cooling out of this. I think your contact pressure between the peltiers, heat sink, and water blocks can be improved to get some better cooling. Zip ties could be a quick solution as a test, but more long term, maybe some cheap metal bracket fashioned together from straight pieces of aluminum across the top and bottom sides, with long bolts running on the outside to squeeze together. You'd need to insulate the cold side from this bracket, or heat will transfer from the hot side through the bracket. Perhaps some thin insulation from an insulated lunch box would be enough to separate the bracket from the block, yet still be stiff enough to squeeze it together stronger.
Ditch the metal tape. it will conduct (a small amount of) heat thus lowering efficiency.
Have you considered running these peltiers in series? As in, Hot side of peltier A to the heat sink. Hot side of B to the Cold side of A, and Cold Side of B to the water block. The Pelties can only maintain a certain amount of delta T across them, based on current (higher current = higher delta T). To make the cold side colder, you can cool the hot side more aggressively. If the hot side is begin cooled by the cold side of another peltier, you may be able to double the delta T (or close to it) across the whole apparatus. Your heat sink will need to dissipate twice as much heat, so it will be much warmer to the touch and the fan will need to run at full speed. if each Peltier is 5 amps, that would mean 120 watts of heat to dissipate. A medium to high end computer heat sink fan combos for a CPU can usually do at least this much (sometimes up to 150 Watts), while keeping the hot side below 60 C. You would only need a delta T of 30 C on each peltier to freeze the water, in that example.
Insulate the water tubes to further minimize the losses.
Some have suggested that the orientation of the heat sink is important. I'm not sure about that. Most computers have their CPU heat sink oriented sideways, just as you have in your device. The conventional wisdom is that heat rises. This is true in a medium like air, which is less dense at higher temperatures at constant pressure. The copper/aluminum isn't going to work that way though. For one, the metal isn't circulating in a convection current. the heat pipes in the heat sink have a small amount of liquid that evaporates at a set temperature. It then travels through the tube to the cool side (fins), and condenses, releasing heat. It travels back along the inner walls of the tubes due to capillary action, to be delivered to the hot side of the heat sink again, where the cycle repeats. This does not depend on the orientation at all. It does mean that you have to warm up the heat sink to that evaporation point to get the most effective cooling out of your setup.
Good project though. I like it!
This is great! Thank you for such a detailed walk-through - great pace. Has anyone asked about trying this to make a an air conditioner by running the chilled water through a radiator and then blowing air over the coils?
It is possible, you would have to ventilate the heat to outside and depending on the size of the room, you would also have to scale the unit to produce the amount of BTU's you need to cool.
Nice work.
I want to see this done for a pc watercooling set up.
I wanna see it on a PC water cooling system!
would be interesting to put one of these into pc cooling loop to see if it helps cool water better
i once tested a setup similar to this on a Athlon 2 core and was disappointed
@@picklesthegreatest I know about that I meant to use it as extra cooler in the loop just for the water
@@picklesthegreatest where's the point in putting a peltier element between a normal cooler and the cpu? you'd get worse performance because a peltier element will put out more energy than it can take out of the cpu?!
It wont help whatsoever, unfortunately. The reason for this is because every cooler has a specific heat output. A peltier device creates more heat than what it is cooling down and therefore creates even more heat for the heatsink to output. Not only that, but a peltier device also have poor thermal transfer compared to the standard copper/aluminum block. What it can do is cool down your heatsink so that there is more ΔT of the mass to heat up, but eventually even this would equalize and the poor heat transfer of the peltier would still allow the cpu to be significantly hotter than the mass anyway. Lastly, anything that is cooler than the air around it will condense the moisture in the air and this pose a risk to most electronics.
This man is so dapper, I am sure he wears bow ties everyday and is so swell.
How long it will take to reduce the temperature from 31 deg Celsius to 24 deg Celsius . Can i use it as aquarium chiller ?
good video, and good work
Hey dude, I am just looking into this whole "peltier cooling" thing for my own PC. I personally love the aesthetic of an aircooler and so I am going modify it by simply putting the peltier plate between the heatsink and the CPU... with thermal paste on each of those surfaces.
I wanted to know what power rating (if that's the right term) your peltier plate was in this video. I have seen 50w, 100w, 150w... etc and I wasn't really sure which would do the job for a CPU.
Do you have any ideas?
Just saw this, i need it for my dwc im working on for my vegetables. Thanks bro! I will say that links for the components would have been very helpfull or even a list of things needed
Really cool video, I used this system in my room air cooler :D
Really nice.
So I have a smaller 4 inch cooler like you built with a 100w chip I have it recirculating water in an insulated 10 gallon beverage cooler to cool a 10' copper line coiled inside of it. The copper tubing comes In from another container to cool my co2 laser tube but I do not seem be be getting any cooling effect from the peltier, even if I cool down the water with ice to the proper temp it need to be the peltier will not keep the water temp maintained. Any suggestions?
I have a question regarding the peltier chips. In order to transfer let's say 100w of heat through them do I need a 100w peltier chip or they just speed up the transfer between both sides no matter the power. I'm wondering if there is a benefit to using a small power peltier chip between my cpu and cpu block to accelerate the heat transfer. thanks.
The peltiers have naming conventions that mention its maximum current intake and its operating voltage you can calculate the power from there. You should look it up :) for example in "tec1 12706" tec stands for thermo electric cooler, 12 is the vlots and 06 the current in amperes. idk about the 7 and 1 lol ..
Loved your vid
Great video, just subscribed :)
Do you have a redo for where I should buy my peltier coolers?
practical and imaginative thankyou
I need one help from you
How long time put it on peltier device
Actually I was thinking making one small AC with 10 peltier device and water radiator behind the fan
And I am using AC fan smaller size
And I was decide to make cabinet minimum 2 by 2 feet
And all the heat sink I will keep front side of the fan
How is my concept please help me by comments
4:33 Aha! You called out exactly what I was here for.
Can you adjust the temp, like put in a potensiometer in it?
How long can this continually run? /hours, days..
> looking for options on running the output through a small hose, looped through several feet /length to cool down aquariums in summer & maintain certain temperatures for coldwater animals.
Chillers are pretty expensive; other Peltier units I'd seen only knock down a few degrees, though this one seems much better.
Awesome video
Hello this is good job. What is your mini color screen thermometer name or model?
What happen if you connect feltier chips directly on the CPU? Just like you did in this video. It would properly cool down CPU? or it won't be cooled as effective as intended?
THANKSGIVING
Great concept coupling, I have one point that can improve your efficiency. The heat sinks you used are designed to function only in one direction (oriented in one particular direction). Be sure to orient them in the same direction that they were in while they lived in the CPU. If I’am not mistaken the copper is a pipe or tube containing a refrigerant if so it’s a heat tube, relying on the phase of the refrigerant from liquid to gas, and back from gas to liquid.
You're right the, tubes contain a refrigerant. But they don't have to be oriented upright as the interior walls are lined with a porous sintered metal powder which acts as a sponge, constantly drawing liquid back to the hot end.
Great video
You have links on where you got the parts?
That project is awesome. I want to build something like that but i dont know if the materials on my list are compatible, can you help me?
150 watts ,now how much power is a micro compressor and efficiency vs this system?
good clip, i didnt know about the inside of the water cooling block, but one question :- in the water circuit are you relying only on the temp gradient to allow the water to circulate, is the water pot open ? and not simply the pipe going through it trasnferring cooling ? Im building one of these to up the cooling of one of those chinese protable fridges - as its not cool enough. I dont think you explained the heat transfer mechanism enough :-)
hello did you manufcature the water block yourself? im looking to cool water through tbis method as well for a project but lack this very interesting aluminium piece where the water runs through
could you add this to a water cooling loop for a pc to keep the actual water cold in the loop
I wanna try it...thank you.
How does it compare relative to a normal cooling set-up?
Hey dude, thanks for the video! Can I ask you where you got that awesome thermometer at 4:14?
this set up can cool a 50liter reservoir?
what glue u used to stick pilter ???
Great video, how long did it take for the water going from ambient temperature to 6°C?
So using two systems is just to make it cool faster? I'm attracted to the first one as my setup is quite small tank, 30*30 cm. would 1 be enough?
i'm wanting to grow tomato's hydroponically outside in a 5 gallon bucket, root rot is something of concern because of high water temps.
if i use this to recirculate the water in the same bucket, (into itself through a watering ring), do you think it would cool the water to a reasonably lower water temp?? temp outside is like 90 degrees.
Hailea HC Series Water Chiller, it just works with no messing about..
I cant help thinking your results would be sooo much better without that round of insulating tape between the blocks. Still, great video, great cooling rig and a thumbs up for you.. well done buddy!
Sir , Would plz mention the market names of each part so that I can
make myself. You workmanship is unique. AMAZING
Ok it’s stupid question the thermal grease dose it ever get hard like glue or dose it just stay soft and only transfers heat and cold?
Can I use the piltier with laser machine chiler "cooler" because the cooler is law quality and didn't down water temperature
Could u use that to cool a CPU with the cooled water ran to a CPU block
Good project; and you can flip the PELTIERS CHIPS YOU CAN GET WATER FROM AIR AND YOU NEED TO COOL HOT SIDE . BY condensation of water vapor
Good, now that it's in place and worked... How are you going to use it? I mean in what way does that thing supposed to be used?
trying to do something similar but run the chilled water through ~15' of tubing. Can you provide info on the TEC you used, pump, heat sinks etc? thanks
Tom DeNapoli Each TEC was 60W so I used 1 CPU cooler for each one. most CPU cooler have a cooling power of at least 80W so there should be plenty of extra cooling power to run the chips. The pump I used was just a cheap eBay pump. 240 L/hr. Now bear in mind that if you're going to run 15' of tubing, you're going to be losing a lot of cold. Use a well insulated tube and try to keep the length as small as possible if you want your water to stay cold.
Were you using tec1 12706 chips?
what hoses did he use? Like what Inside diameter ?
i wish you've shown the results of the cooling on the pc hardware.
Daria certo eu usar esse sistema para tentar resfriar o ar da admissão do meu carro visando ganho de potência ou não compensaria?
You can improve the overall performance simple turn your assemble 90°. The reason is that the sifon effect will works better, because the hot fluid inside the copper pipes of the heatsink always goes up, allowing the more dense cold fluid flow down. Try and see.
this seems like a long time ago but why do you need two peltiers systems to cool a small amount of water?
im about to build one of these but i think i will submerge the hot heat sink in a pool of water instead of using a fan which would blow heat into the room. I would love to know how hot the heat sink gets. and what CPU cooler you used on this
Crypto Noob If you submerge the heat sink in water then the water will heat up and your heat sink will no longer have anywhere to dump heat.
how hot is the air exhausting it with the fan?
I like your video very much but I don't know where the peltier is found
ebay
liked it , now how do I use this for my pc ???? I live in Mississippi one of the hottest places, as its also with the highest humidity!Which can result in very hot chips. Show me!!!
hey bro, I am using small heat sink and fan attached for a CPU with fan dimension : 70X70X25mm, heat sink dimension : 80x67x25mm, with fan speed : 2500+- RPM, via adapter 12v and 5amp, for a cold water dispenser, it comes with 3 wires, black, yellow and read, I connected plus terminal to red and minus terminal to black, it it really slow, takes ages to cold, am I doing it wrong?
Bishorjit Meitei Try connecting the 12V supply to the yellow wire instead. It may spin the fan faster. If that's not it then I would point to efficiency. Make sure your water tank and hoses are all insulated so that the air isn't warming up your water. Depending on how much water your trying to cool, you may consider using multiple cooling chips like I did. The more you have working, the faster heat will be drawn away from the water and the more it will be able to resist losses to the air. meaning it can get colder.
What was the orginal water temperature?
can i have the list of the equipments.
Inside like a dioda? Positivfe and negative?
Can you please let me know what CPU coolers those are? I have yet to find ANY CPU cooler that has a 40mm X 40mm base, most are 35x35mm i have found 35x40mm but cant seem to find any that are 40x40 or larger for the contact area. Also i am curious what that reservoir is called that the water is in? Thank you!
Check my Peltier-related videos, I share the exact parts I use in the description of the videos. I also had the same issue as you, the coolers I found were only 35x35 mm. I found some cheap, 6-heatpipe mode which can cover the Peltier perfectly.
what if you put two peltiers stacked and used single fan?
Would this work well for overclocking cpu/gpu with proper condensation isolation, or you don't think it is efficient/strong enough to keep temperature down. Because i heard those tec chips aren't all that efficient compared to a proper ac refrigeration unit.
leomastersxd It would depend on how many of them you have. A 100W heat sink can move 100 Joules of energy (heat) per second but it will bottom out at room temperature. If you put a peltier chip between the heat source (CPU) and the heat sink, your heat transfer efficiency will be lower (the chips are lower than 100 watts) but you have a lower minimum temperature. Having more chips with heat sinks could negate the efficiency loss. But obviously if you have to have multiple heat sinks then you would need to run it as a water cooling setup. Simply because you can't fit more than one heat sink on a CPU. But ultimately, this is a less efficient way to dump heat than a compressor style cooler. Although it depends on your needs. A compressor is more efficient but it's louder and bulkier. Peltier chips are less efficient but they're small and quiet.

Magneto! Only way to know for sure is to test it.
How much power does this Peltier module based water cooler consumer I want to make a similar project but worried about the power consumption in a month in comparison to a normal compressor based cooler
The power consumption will depend on the thermal load, the efficiency of the chips, the ambient temperature, and how well heat transfers within the system you build. These chips are rated at 60 watts each. Although I didn't measure, I suspect they were operating at a lower power consumption due to the factors listed above. If efficiency is desired, compressor style refrigeration is far more efficient than Peltier chips.
Where is the water pump to move the water, or cooling fluid?
Nice video.I need one information.I live in southern India where in summer temperature goes up to 40 deg c and humidity will be 77%.The roof of my house is made of concrete and to reduce heat I gave metal sheet roofing still I cant find any difference in reducing the heat inside the room especially during night time.I would like to know if I could moisten the metal roof by fixing flexible vinyl tubing on top of the metal roof and putting finer holes on these tubes.These tubes can be connected to the super cooled water from Peltier and circulate the water using a medium size aquarium pump, so that the roof gets cooled down and the room temperature will be reduced.But will this idea work ?
No,your best bet is to hook this thing up to a computer radiator and let it cool your room.
Could you do the same concept but to cool a CPU? It's gonna be very interesting to see the results!
The problem is that kind of pelter would draw several times the CPU wattage and you'd need to cool the hot side down.
Pelter are very inefficient.
Hey bro it’d be dope if you could answer this, you said it will last for hours but do you have any idea how long? I’m trying to keep it on for 24 hours a day
Is it possible to use these chips to make a cooling jacket with tubing and water or some coolant. (My work is hot)
Yes. But but be aware that the amount of heat released from hot side of the chips is much greater than the amount of heat absorbed by the cold side. Depending on how large the place you're working is, the exhaust from the heat sinks might make the air warmer. I hope you'll build it but don't forget the cooling power of a wet T-shirt and a fan.
@@SafetyLucasthank you
how many time for 14c?
Can you use this for a dwc application, as it runs 24 hrs a day.
Great video been looking for something like this.
from where I can get that peltier .......
cpu,or laptop?
Its not from a computer or laptop (except for few exceptions where you could get a performance cooler like cooler masters V10 i think it was called) these modules can be found in simple car fridges or bought at electronics hobby shops
how can you limit how much power it draws?
The critical thing with peltiers is not so much the power of the module itself, but the temperature differential between the hot side and the cold side, or the delta-t. In order to maximise the cooling on the cold side, you have to dissipate the heat that is being moved to the hot side efficiently. You will not achieve that with a heatsink and fan, which can only cool to room temperature at the very best. If you cool the hot side with a water cooling solution, the cold side will become MUCH colder with the same 'power' peltier.
Good but please add more peltier combined as one
Is it possible to just put one of the modules over a cpu? Directly exchanging heat without water block.
No, these modules are not efficient enough to keep up with the cooling demands of a CPU. You would need multiple chips in series connected with a water loop to cool a CPU.
Why not use thermal-conducting epoxy between the two waterblocks? I'm not sure how strong those are, but they do provide better conductivity.
The electrical tape fucks the contact b/w both plates well done 👍
Where did u get the heatsink from?
0:39
What about using an air pump or a fan connecte to a funnel, to send high speed air through a smaller pipe to the entrance of the liquid cooling square (which is put on top of the CPU/GPU), to deliver high speed airflow for cooling, instead of water? The downside would be that the cooling square would have to have thin sheets of metal to act as a more efficient heatsink.
if you just want cool air, flip the peltiers and use the water to remove the heat.
ghetto AC
@@lordsqueak Just take 2 of those heatsinks and put a peltier inbetween then. Cold side heatsink blows in and hot side out.
But why?
@@lordsqueak because then you'd get an ac... but youd have to use it as a window ac to blow the hot air out
But that's what the water is for. removing the heat.
But my reply was just a quick answer to the original poster, instead of doing all that, just flip the peltier.
Of course now things have gotten way too serious, but if you really want pelters to cool air, more permanently, the best way of doing it is to use tap water to remove the heat. (wastes water, but that's besides the point here)
all in all though,, using peltiers is not optimal.
Is this food/drinking safe?
i was gonna say pump the cold water over the cold side of TEG. but then i realized.. lol, nice build. i want to use TEG to cool solar panel.
