I think just running one of those aquarium coolers after the radiator would suffice. Putting a peltier into the reservoir would add complications. It may be better for space. But it's not necessary for a proof of concept. Something custom would have to be designed and possibly 3D printed in order for that to work. For a commercial product, (assuming a peltier helps) it would sound like a good idea though.

@@UltraNoobian Sure, no doubt, it's a ridiculous amount. Really nothing uses that much power besides like a fully operating entertainment system, a computer, some power tools. I've got a fan that uses 384 watts, it can pull all the air out of a 12x14 room in a matter of seconds, so for that to be just a very poor quality cooler... nah. Would probably be more energy efficient to use an ACTUAL FRIDGE with a huge spool of tubing in it lol.

[@1234567890CAB]

Watts = Volts × Amps Anyway the reason it needs to draw so much is because it is actually working as a heat pump. Basically all refrigeration are heat pumps where heat is being pulled out of a low energy state (your cold food or room) and being "pumped" up and out into a higher energy state (ambient external air). But in order to do that the pump needs to be powered with equal the amout of energy being moved plus efficiency losses. So if the CPU is consuming 100W a perfect refrigeration system that's 100% efficient would have to consume 100W to bring the CPU back to ambient temperature and even more to get it below ambient.

The power consumption was nearing 900w but with 2 360mm radiators and the water temperature around 30C, I was able to cool i7 940 (yeah I not gonna use this on anything too new) at 4.4ghz at 1.43v while remaining sub ambient.

The Peltiers becoming an insulator is absolutely true. I bought 2 of them as a kid to cool a CPU and if the CPU gets too warm, they basically become heaters and the more power you dump into them, the more heat comes from both sides…

[@zainrei4917]

@@marioj6330 well a peltier module has a ratio of what maximum heat it can dissipate. lets say if your hot side is on 50 C then the cold side will be 5 C. but attach an radiator at the hot side to reduce the tempt to 25 C then the cold side will be lower than 0 C. now back to your question. it cannot reduce the heat of a cpu because the cpy destroys the hot and cold ratio on the 2 sides of the peltier module. the radiators or lets say heat dissipation system is not instantaneous and not 100% efficient as it can only draw such heat from the source. Thats why when the cpu is running and getting hotter, the peltier follows that hot and cold side ratio but with the cpu running the cold side is 30 C warmer(still increasing) and the hot side is already burning hot 70 to 100 C. the figures i said is just for representation and not its true value if applied in its formulas. but you can get the point of why it does not reduce the heat of a cpu

I had an idea a few years ago, but have lacked the motivation to try it out. You keep the traditional water loop setup including rad, but insert a peltier device into the loop after the radiator. You have a thermocouple on the water block that is connected to the peltier and a humidity and temperature sensor measuring the ambient air hooked up to a micro-controller which controls the voltage applied across the peltier device. The micro-controller ensures that the temperature of your coolant never goes below dew-point, so you don't have to worry about condensation, and the peltier does not draw as much current. There is definitely some risk here of your radiator actually working in reverse and heating the coolant, depending on the thermal output of the system, but if you had a loop that cools not only your CPU, but also GPU and potentially MOBO chip-set (and maybe even RAM - because after all this is a crazy idea in from the get-go), I think there is little chance of the coolant reaching the rad at sub-ambient temperature.

A coarse estimate told me i can expect 175W out of the CPU package on my current overclock. I think i can do more than 300W at least.

[@SianaGearz]

​@@technologyanimals Yeah well certainly not brave, broke and indecisive. Phenom II is no longer fully usable. While the performance is still borderline tolerable (but it's been 9 years since it used to be a high-end CPU), the compatibility plain isn't, newer software frequently demands SSE4.2 or SSE3S and those are left missing from the CPU. But i paid mere 110€ for the CPU new from a store, and it served a fair good while. There was a time a few months ago when all the stores were dumping their FX-series stock and i could get something like an FX-8350 for 70€, but those are gone now, now you'd have to pay silly prices on the used market, completely indefensible. Will be considering a full system rebuild with an older-gen Ryzen. Alternatively i could snatch up a cheap FX-6300 or something - while the performance is likely to be a wash, at least the compatibility would be better and i can probably limit the power draw quite a bit. I am awaiting delivery of Shenmue 3 and i'll probably be interested in CP2077 and probably Watch_Dogs Legion. Then again i won't pay full price for Legion so that'll have to wait a year anyway. Legion won't run on the Phenom, if all the last year's Ubi releases are anything to go by, and a severe suspicion that Shenmue 3 and CP2077 won't either.

[@SI-GOD]

The TECs can stacked. The TECs give approximately a 30°F difference. So when you run water across 1 and then another, you give it more time to lower the water temp but can never get below the limit of ~30° before ambient temp. However, if you put 1 TEC directly on top of the other, then you can get ~60° drop in ambient temp. Now try putting the TECs directly onto the CPU (using thermal paste). You can then put a water block on the hot side to send the fan cooling to another location. You can also use antifreeze in the water which absorbs heat better than plain water alone. There are other chemicals that absorb heat even better but some of those are expensive or they are poisonous to breath (ammonia) and so not good for residential use.

I had a CoolIt! cooler (whatever their higher end one was called) back in the day. The design was quite different from this; it was effectively an AiO cooler that had TECs between the loop and the radiator. Worked quite well for several years, up to the point that I ultimately had a pump failure.

[@brandonroeder2461]

The pumps always fail on these units. Im still using a modified FreezeOne that works on modern cpus. Replace the pump, the fan ( 120mm mod ) and the block and you have a great cooler.

[@lalPOOO]

[@GuigEspritDuSage]

I remember to have done the calculations for Peltier cooling on the late 90's or early 2000's and the numbers get really fastly big. When you use a peltier, you want: 1°) deltaT (hot temp - cold temp) as big as possible. 2°) hot side (and so cold side) as cold as possible. Then comes the problems: A peltier element can achieve his maximum deltaT when the heat input in 0w. When the eat input match the peltier maximum power, the deltaT become 0°C. It means that a peltier has to be much powerfull than a CPU if we want it to be well-cooled. So for example a 25W AMD K6-2 from this old times, to be quite well cooled, you need a 80W+ peltier. A 80W peltier means 80W power absorption capacity. And so 80W+ power consumption and eat generation. So the cooling system have to be big enough to evacuate 25 + 80+ = 105+W heat instead of the 25W from the CPU alone. Also sometimes, a peltier fries. So he become a powerful heat generator, leading to to the CPU to follow it in his death.

[@XtremeConditions]

@@SimonWoodburyForget I guess, but isn't the whole point of an air conditioner is that the reactions that occur outweigh the added heat of its power consumption, if that makes sense? Well, certainly in that it pumps the heat away, so I guess it doesn't outweigh per se. Or does it..? That's interesting and a whole other question I guess. This almost sounds like you're pumping electricity directly INTO the device that needs cooling. But I guess that's not quite what's happening either the way Alex explained i. It just seems like this whole thing is a waste and that if it ain't broke, don't fix it, you know?

[@Chris.Davies]

I successfully used an 80-watt peltier on my PC back before you guys were begging for happy meals. I inserted it between the CPU and the heatsink, and used lots of silver-based thermal goop. With the exact same fan speed settings, I was able to drop the core temps by 6 degrees C, and thus achieve a 67% overclock, compared to a 50% overclock. That meant I saved about $1,000 on the CPU. So the extra power wasn't really an issue. More recently, I designed and built a Peltier-based stove fan for atop our fire. It uses an alloy base to absorb the heat, and a massive old Coolermaster heatsink with 6 heatpipes. The temperature differential drives a 12" RC plane propellor which blows air over the heatsink, and maintains a 40-50 degree C difference between the two sides of the peltier. This generates 1.3 volts, and enough current to drive the propellor sufficiently quickly to remove a huge amount of heat from the flue. To avoid heat-soak, the device has to sit perched right at the front of the fire, so that cool air from in front of the fire can be pulled in to cool the heatsink. The thing is so well made, that it starts automatically when you light the fire, and it runs until the firebox cools to the point you can just touch it.

[@gregorymalchuk272]

Exactly. A properly designed thermoelectric cooler system can definitely work well. Stacking 2 of them in a multistage configuration also tends to increase the Coefficient of Performance (COP) and decrease electrical consumption for a given amount of cooling.

[@johnjamison4579]

The Peltier needs to be PID controlled to maintain a constant CPU temp. There's not really a need to keep the CPU so cold. A proper PID will be able to regulate the peltier to keep the CPU from getting too cold. The PID also needs to be limited so that the Peltier doesn't operate at currents much higher than the COP maximum. That way when the CPU outpaces the Peltier the PID doesn't go past I_max and cook everything.

[@tubesman7]

If you look at how to cool an electronic device you will see one concept. Thermal resistance. A CPU connected to a heat pipe connected to a heat sink cannot cool better than the same heat sink connected directly to the same heat source. Every interface raises the thermal resistance, and causes the temperature of the heat source to be higher. The purpose of thermal grease is to get rid of a CPU, air, heat sink interface. Thermal grease is a lousy conductor of heat. But, it is much better than air. If a Peltier device is connected directly between the CPU and heat sink, it will work better than between a CPU, heat pipe and heat sink. The only reason I can imagine for a heat pipe is to put the heat sink someplace more convenient. A more modest goal in temperature reduction, of like 20-30 degrees above ambient would be doable and adequate, as long as the ambient isn't 80C! It would have no risk of condensation. Keep the CPU above the dew point, instead of trying to go cryogenic. If someone wrote a program that would keep the CPU at a fixed temperature or fixed temperature differential with a Peltier, instead of flat out max power, I'd be interested.

I would love to see a project where you have an array of Tec coolers cooled on both sides by two large water blocks, where the cooling capacity is greater than the max power consumption of the cpu & gpu. You have the hot side a water loop to dump heat to probably 3 rads each with 3 120mm fans. Then the chilled side, a water loop to your cpu & gpu. It seems key to me to have the TEC coolers controlled by an arduino, that is monitoring the discharge cold water temp from the TEC, and comparing it to the local dew point inside the case, cutting power to the TECs when you’re within 2 degrees of the dew point. It would probably be a good idea to have thermal mass in the cold water loop, for when cpu and gpu ramp up and down. Maybe an insulated LTT tech bottle? Probs wouldn’t hurt on the hot side, but not entirely necessary. Little things I would then geek out on are the cpu and gpu being piped in parallel on the chilled water loop, with balance valve so you could divert flow for optimum temps between the two. I’d prob have all the hot flow go through 1 rad first (as it would be at high temp and thus dump heat quickly with the air), and then the second rads in parallel, running at lower temps but having a lot of air to approach ambient. Maybe experimenting with arrangements here would be fun. But the key part of it all is that arduino monitoring chilled water temps, as to not have condensation on the cpu or gpu. Which I think is one of the main faults with the coolers shown in this video, second only to their cooling capacity being much lower than the max power consumption (thus heating capacity) of the cpu.
