its really not, the only problem i see here is the surface area the radiator covers vs the waterblock. the water goes through so many small tunnels with a bunch of fins on the side that cool the water instantly and efficiently with a radiator and the waterblock well its just a block of copper. try cooling a bucket of water with an ice cube.

@@rookm13 Actually it is a terrible idea. The TECs power consumption would need to be higher than the thermal output of the CPU and since the TEC also produces heat, the cooler would need to get rid of the combined heat of CPU and TEC. I am to lazy to calculate this, but with modern CPUs that's a lot of heat. Probably way north of 300W.

@@andreasvogler1875 ah, maybe he could put it in line with the existing radiator. That way he could extract heat from an "already cool" line

The Peltier element has a certain cooling capacity, once you put enough heat on its cold side it gets overwhelmed and the heat stays trapped in the water loop. Off the top of my head, when I was cooling Pentium III CPUs which had a TDP of around 35W, my 60W Peltier (12V 5A) couldn't keep up and I got worse temps than without the TEC. I would say you need to put at least 3x TDP's worth of power into your TEC, or across multiple TECs, in order to get any cooling at all. So for a ~90W TDP CPU you would need at least 270W worth of TECs. That would be 5 60W elements. You should go for at least 7 or 8 to have some margin, and maybe even to get sub-ambient at low loads. Is this expensive and outrageously inefficient? Yes. But it should be cool. EDIT: I should also add - don't stack your Peltiers, keep them at 1 element per tower cooler, and chain the water block+Peltier+tower cooler assemblies in a water loop. Maybe add a radiator without fans into the loop to provide a sort of heat buffer, without a radiator the total thermal mass of the loop is small and you might get large spikes in temperature.

IIrc they are about 1-5% efficient. so at 2%, you're looking at a 12710 (154w) cooling 3,08w which means you'd need 35 to cool a 3950x (105W) though you could bring it close to ambiant with a 3x3 radiator, and use like 2kw of tecs to bring it down a few degrees below ambiant. but the best option is probably salvaging an old ac unit and make a chiller with it. (or cool antifreeze with it.)

I think if you had the fin stack the right way up, helping with convective heat transfer it would probably help a little better.

Oh hey, I just recently graduated with a thesis based on trying to cool a CPU with Peltier. The result of that is pretty simple: Unless you have an IHS the size of a Peltier that is capable of moving MORE heat than the CPU produces - you cannot cool the CPU. Heat transfer rate of such Peltier module is way too low, hence it must be stronger than the heat source. And the moment you start pumping say 100W from the CPU you have over 200W of heat to take from the hot side. I've used a 40x40x3.2mm (TEC1-12715) module with Qmax of 144W, at peak efficiency at 13.2V (powered from a PSU that supplied my PC, had to use DC-DC boost converter :D) it I still got a score of 59C under 65W of load, as a reference I've used Liquid Freezer II 360mm, which managed to keep that temperature under 95W. And boy, was the radiator of that LF II warm when it cooled the Peltier under this 13.2V. The only way of "efficiently" using Peltier module is for a burst stress testing, such as a CPU-Z validation. Also, sides of the Peltier are terribly wavy, you need to spread the paste manually.

But that’s compared to say my over 100% cooling efficiency of my phase cooler (where it uses about 350w when cooling a 350w CPU at -35c, which is the hottest I have ever seen it get, just a basic Vapochill LS and I was testing an FX-8350 at 1.7 Vcore but my garbage board with only a 4 phase VRM could only get it to 5.5 GHz rock solid, or 6 GHz single core, but it would basically be 9900k at 6 GHz at that temperature for modern comparisons with similar power draw since they get much more efficient at these temps, I’d guess the FX was 35% more efficient because with the power draw scaling it would have been around 500w if by some miracle a waterblock could have cooled that volcano below thermal shutdown). I think it can handle a little more heat load (especially if it’s just a burst (maybe 400w cooling capacity at some temp maybe like -25c), but it’s far too small for my Threadripper (which sits happily on a 120mm AIO chugging through compression encodes all day long at 450w with it overclocked).

@@satibel that "over 100% efficiency" is just an artifact of how you are calculating that efficiency. If the system is at equilibrium and we are assuming it is an ideal system then if you are putting 350W in at the pump and getting 700W out of the hot side then you are pulling 350W from whatever it is you are cooling. And the proper way to calculate efficiency for this type of device is, desired/input in this case the energy transfer of the cold side is our desired metric so: 350W/350W=1.0 or 100%. Just knowing work in at the pump and energy out of the heatsink isn't enough to calculate the actual efficiency of the system. In actuality the efficiency is likely closer to say 0.9 so if you are putting 350W in at the pump you will be pulling 315W from whatever it is you are cooling.

One thing that may have an affect is the direction of your air cooler. The heat pipes are designed to bring heat away, but it might be more difficult with the air cooler upside down. The fluid in the pipes will rise when it gets hot.

There was actually a KZread video on someone doing this a good couple of years ago on the "Then Blazing Fast" AMD Athlon. They had the xavt same issues, and resorted to conformally coating their MB in something to avoid destroying their setup. If recall correctly, they were averaging around the 5° mark as well 🤔

In the realm of techtubers, you've definitely solidified your place as the Mad Scientist between stuff like this and the ongoing fan experiments. I love it! Revisiting this with a better peltier and a larger/better waterblock would be a worth it. Maybe place your reservoir between the blocks so the CPU block is receiving the coldest water?

Dell offered a water loop with a Peltier block called H2C. The XPS 710/720/730 had it as an expensive option. It was regulated to not go below ambient temperature. If it goes below ambient temperature the radiator starts adding heat into the loop. This also avoided condensation issues. It had 2x Peltier chips after the radiator. Peltier can easily go well below ambient if you have enough of them. But then condensation will need to be considered.

Now im curious as to how that would work without the Peltier element.

i have been waiting for you to do projects with peltier coolers :).. i have a little idea.. try put the peltiers on the radiator , or peltiers in a closed box and then have the heatsink with the hot side stick out of the box so that does not generate heat inside the box, and for better cooling performance you could add a heatsink or some other metal block to the cold side on the peltier inside the box with the radiator i think that might think that could work , also remember to add rgb light for extra cool performance

Yay. The idea behind it was based off one of those ancient fad coolers that had a peltier built in. This was before there were dedicated water loops so I was wondering if the new water loop tech and new heatpipe tech would make it worth giving peltiers another look. I was thinking it would at least allow for supplemental cooling or relocating a big tower cooler. I am bad at math, and a lot of the comments below seem to confirm this. Running off 12v just doesn't seem like enough juice and the thing just gets saturated too quickly. To get around that (if still possible, which it's probably not) would require additional crap that would defeat its intended purpose. I am just glad this didn't set you back too much.

I had an all in one, CoolIt peltier setup years ago and that definitely worked. It had 3 peltiers sandwiched between 3 little water blocks (joined together in a loop) on one side, and a round central doughnut like radiator in the middle, on the other side. One end of the radiator doughnut was closed and had a waterpump bolted to the back side, the other open end had a fan sucking air out the back of my case. It used a lot of power but my temps never exceeded 20 degrees celsius.

Since you already have all the components try this simple modification: CPU block -> radiator -> peltier block -> back to CPU block Let's see if is possible to achieve sub ambient coolant temperature. Added bonus, use your water cooled air cooler to cool the peltier for extra lols! And if you use the cooling tower to cool the coolant of the water cooled air cooler it would just be PERFECT!

Now I know the definition of “contraption”, thanks! 👍

you need more peltiers than 1 in order to cool a cpu. I'd say get 7 more and then try again. But this will work you just need more peltiers

it's gonna freeze on the surface of the TEC

Try running through a rad to drop the temps to near ambient, then run it through the peltier to reduce temps even more.

Here's a challenge for you: somehow merge two water blocks into a single double sided one and put one of those air coolers on each side

I used to have a pair of 40x40 TECs to cool a water loop. I customized a DangerDen 5.25" Acrylic Tank by removing the bottom piece of acrylic and replaced it with a 1/16" piece of aluminum sheet metal. The TECs were attached to that with a couple of CPU coolers and fans. The loop was Tank -> CPU -> Pump -> Radiator w/Fan -> Tank. The idea being that to get the coldest coolant (read automotive antifreeze basically) possible it needed to spend a lot of time resting on the TEC and be as close to ambient room temp as I could get it. I think I managed to get about a reasonable drop over ambient room temps but it was a PITA and these weren't the cheap wish.com style ones either. Honestly, I wouldn't run that type of setup again, modern water cooling systems are much more efficient than the early 2000s when I used to tinker with trying to OC a CPU to within an inch of its life and such.

Im no scientist but I think the reason this didn’t work is because the surface area of a water block is so much smaller than one of a radiator maybe if you put the then cooler between the cpu and block it would work better

You deserve way more subscribers.

Betteridge's law of headlines. Betteridge's law of headlines is an adage that states: "Any headline that ends in a question mark can be answered by the word no."

Need more! How many Tek/heat-sinks does it take to actually cool? 5? 10? 20?

I really think if you get some decent waterblocks and a couple better peltiers and but them in a series to cool the water, you could get some cool results

Use a rad to cool the water coming from the cpu, then a Peltier+air cooler to chill the water below ambient before it reaches the cpu's waterblock

MJ you are the king of crazy cooling, would love to see you do the same with crazy case mods especially cheaper cases

If you want it to work then either you want the Peltier modules to be directly on the CPU and have a water block on it or you could have an fan cooler on it.

*@Major Hardware* Where do you think the bottle neck is in that peltier setup? The water cooler?

I always thought the best way to do this would be to use a peltier + air cooler in addition to the radiator. AFAIK the peltier's goign to be sucking X number of watts out of thermal energy out of the water regardless of delta, right? So have the water go out of the cpu into the radiator first to dump as much into the air as possible that way, then when the delta is lower use the peltier to push the water temperature down even further.

Peltiers can move heat using electricity, but they're very bad heat conductors. This means that while yes, they can cool down things by transporting heat away form them, they do it at a very slow speed, therefore they only really work for things that don't generate heat by themselves, like the inside of a cooler, or a can of beverage. You would need a massive surface area covered with dozens (hundreds? thousands?) of Peltiers to cool down the wattage of a CPU!

possible with two TEC of good quality (Made in USA, not the Chinese ones with wrong specs) and a strong Qmax. Did it with three waterblocks, two to reject heat with water and the center block get cold from both side. Not power efficient!

Now hook this up to your air-cooler-turned-liquid-cooler. "Yo dawg, I heard you like coolers. So we put an air cooler on your liquid cooler on your air cooler"

Peltier works. I remember even Cooler Master adding one on their V10. It was a gimmick at that price, but it added something. It just that even if it can make a temperature difference on both sides, it's limited in how much thermal power it can transfer.

As soon as I read Peltier in the title: Nope. Doesn't work. Whatever it is, it doesn't work.

This is something to revisit when you can get your hands on an Ice Giant Prosiphon. And a better peltier. Or maybe stack peltiers.

That's interesting cause by design, thanks to the tech, it should be able to go under ambiant temp! Try again with lots of Peltier in series !

I like that you did it

Have you tried it with the cooler in the designed position? Either sideways, or with the heat source at the bottom? Heat pipes tend to work in the right orientation

Try to incorporate it into a loop with radiator and place the thermoelectric heater before the cpu.

I think the solution is a combination. Open loop, exhaust water from the cpu goes through a rad to cool down a bit, then, connect a series of cpu blocks with peltier/cooler modules, to further chill the water, then send it back to the cpu.

keep adding them up

I know I'm super late to the party, but put that block in-line after your radiator. You stand a small chance of hitting sub-ambient temps. If you're using a $4 peltier its probably able to suck out about 15W of heat, at the absolute best. I've got two "225W" peltiers around here somewhere, and their curve shows they'd be able to move about 90-100W of power. If you wanted to cool a modern CPU you'd need about 3 of them. Also, keep in mind, if you do get sub-ambient you'll need to seal things up to keep condensation from dripping on your board.

i did peltier cooling for a science experiment like 5 years ago. i got a monster of a pad like 300 watts and attached it to a h105 aio with some 9000rpm fans. i was able to keep a pentium 4 at 1c for extended periods. possibly lower since i dont think the motherboard read temperatures below that. loads of fun to do but 100% totally impractical. im surprised how well the motherboard held up considering i was a total noob at sub ambient cooling back then. i put kneading eraser around the socket to help but there was still so much frost buildup on the backside. i still have the cpu and motherboard and they still work!

Hi! I tried to put in the loop, after the radiator. I cooled the peltier with a cpu cooler without fans, just for testing, and i got 3 celsius decrease. Not so efficient, but did something ;)

I don't like the phrase "suck the heat out", peltier cooler doesn't do that, it actively cools the water by consuming power. So weather it's going to work or not purely depends on the cooling power of the peltier. You'd need it's cooling power to exceed the heating output of the CPU. The cooling power is not the actual power consumption of peltier, the actual power will be about 50% more as peltiers efficiency is about 65%.

So the reason why this would never work is that what's happening in the radiator is that the hot water is being cooled via the surface area. The fans push air through the radiator to better dissipate the heat, but really it's just making the radiator work at maximum efficiency. If you wanted the Peltier to cool the water in any meaningful way you'd need to slow the water passing through the Peltier, in this case, you'd need a LONGER Path over the Peltier to increase the surface area of the water. Additionally: The CPU block is designed to draw heat up to the water for the water to then carry the heat energy away, not for the heat energy to be absorbed back down. Basically, it doesn't work going the other way (with the heat source going through the fins and down to the Peltier). So to get this to work, you'd need a way for the water to Zig/Zag over a larger Peltier in such a way that the Peltier has time to cool the water enough so that it no only cools the water down completely, but also can soak the heat energy created by the CPU.

Nothing wrong with experimentation . That fan that you were printing seem intriguing . Add ,remove blades. Looks cool

What would happen if you sandwiched the peltier directly between the CPU and an air cooler instead of using thermal paste (similar to using a thermal pad)? Would the effectiveness of the air cooler increase at all?

peltier coolers were all the rage in early 2000's ...even had freezer towers as well :) however they were woefully inefficient

Better idea? Maybe: put the Peltier cooler on the loop between the rad and cpu, so the rad cools the hot cpu coolant and the peltier cools it down further? Worth a shot!

I think using the radiator with the peltier would be interesting. So as help for the radiator. Thatd be cool

Did you try they same setup, without the peltier cooler in the middle? Just the water block with the air-cooler.

C´mon man, you know that Peltier´s works on a temperature delta. Heat + eletricity = cold on the other side. Cold + heat = eletricity. It´s more efficient to put heat on the hot side and use the cold side to cool the radiator. I think you won´t need the fan.

The peltier chip doesn't directly transfer energy from the water block to the fin. If you're gonna use peltier chips with water blocks you want to use them to keep the liquid cool but they'll need their own way to exhaust heat.

This project can be done to create a water chiller. The main problem is having enough surface area on the cold side. And a massive slab of copper would be quite expensive right now. I actually had a idea similar to this utilizing and dual loop and a heat exchange block in between. Planned to cool the pelts with the alphacool cape cora which is a classic favorite of mine which I have bought. Never got around to the project / extensive video editing.

How about put that setup in line either before and or after a radiator and see how it effects cooling, of at all.

More Peltiers and a larger waterblock to use with them for lower temps, but then I'd suggest monitoring the temp to ensure the liquid doesn't freeze.

I'm wondering if you put a stock or low profile heatsink on the cool side and stick it in a box would it cool a couple sodas or beers?

They sell those... that’s what they use in cars to cool the drinks (they are the $20 soda fridge), of course the heat dumped into your car is 10x higher than what it’s extracting so they use huge amount of power (maybe 30x more power than a regular fridge), but they do use them for that, it’s just terribly slow and inefficient.

Waiting for temps to drop with your hand right on the water block 😂 nice test bud

you should try ading that peltier + air cooler to the rad. loop to see if it make any difference versus the rad alone

Does having the heatsink upside down have any affect on the way the heat flows through the heat pipes?

Did the peltier have enough current supplied? These things can take a lot

I had a similar concept ,except my version consists of a custom-made water block where the inlet and outlet pipes of the water block are mounted from the side of the block, instead of being mounted to the top of the water block, and connected to a radiator. This then allows you to mount an air cooler to the top of the water block to further assist the radiator in helping cool the cpu. Can you see any logic with this method???

One thing pretty much always overlooked is that the peltier cooler will require more cooling than the cpu alone. You're effectively trying to dissipate the heat of the cpu, plus the heat created by the tech. Also, the bigger the temperature delta, the less efficient it gets, and rather rapidly. So good cooling of the tech is essential. So with your setup here, you're effectively cooling the cpu with just the air cooler, plus several thermal transfer layers, plus a heater.

how to make it work: you need a res with the peltier cooling water connected in parallel to the main loop with some kind of valve and thermostat control. the peltier comes on and cools a quantity of water as low as it can go. the thermostat opens allowing the cool water into the loop and new water into the res. repeat. only way to increase the heat capacity is more powerful peltier. if it could rapidly cool the fluid in the res (im thinking 5-10 seconds) and the res holds a similar quantity to the main loop you should be able to do some good cooling.

Cheap Peltier coolers are about 10% efficient. That looks like a 40mm Peltier, guessing about 80w max (power is inverse to temperature differential, so it's most efficient at 0º differential). At that 0º is can pull about 8w off the cold side, delivering 88w to the warm side. That Peltier isn't even close to cooling a CPU, and one that could would take HUNDREDS of watts of power.

I would have liked to see if it would help running inline with the rad. How many deg it would drop (if any) with the peltier in the loop.

Your videos are awesome. I'm binging them right now and I'm kinda angry at the algorithm for not recommending then earlier.

At least you put them to the test instead of just waving them off!

You should try connecting the peltier to the exit of the radiator and run both of them together to see if it does make a difference

I'd love to see a temperature sensor on the tower cooler for this setup, see how it performs, also maybe it'll perform better if the radiator replaces the tower cooler (so, not the same test any more lol)

"Pretty much everything I do on this channel doesn't make sense" LMFAO 😂

The way i used the peltier was doing a chilled water setup. Hooked up the peltier on the side of a reservoir with an air cooler attached and a thermostat controlling the peltier. Placed the thermistor inside of the reservoir. It did work to cool the water down to 5 degrees celcius.

Also, a little advice for using peltiers. The cooler you can get the hot side of it, the colder the cold side will get. If the temperatures that you are trying to cool are too warm for the cold side and you have inadequate cooling on the hot side, the hot side temp will start to bleed through. This will turn it into nothing but a glorified heater. Also, try not to run the peltier at the maximum 12 volts. Run it at say 9 volts. I used a dc to dc converter for this. I also insulated the cold side to prevent the ambient air from interfering with the performance of the cold side.

Your bottleneck is the noctua cooling the TEC. The generated heat must go somewhere so that the Pelt can sustain the diff in temperatures between cold and warm face.
