The TECs did not draw the full amount of power expected because the supply voltage was too low. Looking at the data sheet for TEC1-12710, these modules will need up to 17V, but the supply used was only 12V.

I spent a couple of years playing with TEC's, successfully building out a universal whole case cooler that dropped the CPU temp by 20c while maintaining a case temp of around 10c. So a few things, mounting pressure on the TEC plate is EXTREMELY important, you need even pressure across both sides or performance takes a serious hit. We ended up threading out own bolts with a very high thread density, counting the turns and confirming with calipers. You also need to have a neoprene gasket (cut a hole for the TEC and sandwich between the heatsinks) we used quarter inch high density neoprene, but your application may need something different. We also used 600w TEC's (24v @ 25a) which required a special switching PSU (30v@30a), and HUGE melcor nickle plated copper heatsinks that were cooled with 120mm 120cfm sillverstone fans. The HS's were 120x120x90mm, and each weighed about 5 pounds, with each tec using TWO. You can simply drop the cold side into a container of water, and use as many as you like. The other important thing, you're much better off using high power TEC's like the 600w we used, and undervolting it. At lower power, TEC plates are much more efficient. Basically you're better off using 8 600w TEC plates, running 75w each than you are using 1 plate running full load. I would have to check my 15 year old forum posts, but i'm pretty sure we found that 30% load was the sweet spot in terms of efficiency, though i'm really not sure if that's a flat metric or simply applied to our 600w plates. Either way, i'd suggest taking another run at this, you should be able to get much better results using much fewer parts and a less janky set up.

@Daniel-hj5jt Рік тому
@@heygek2769 I'm sure it is, but they've taken a couple runs at TEC coolers for various applications, and in each instance they've done it rather poorly, ended up with bad, or at least insanely inefficient results, and perpetuate the idea that TEC's are useless. I freely admit, this is a personal pet peeve and this was clearly done for the entertainment value, but...if you're going to do something, you really should try to do it as well as you possibly can. One of the simplest things that is consistently overlooked, is using a TEC to cool the back of your CPU socket. There have actually been a few cases in recent years that have employed fans behind the motherboard tray for this purpose, using a TEC in this was is simply more beneficial, and less complicated than trying to directly cool the chip. Like i said before, i spent years playing around with TEC designs, and ended up with several very viable solutions that i simply didn't have the money to see through, and now i just don't have the time. These guys do, and i'd like to see them make a serious attempt.

You can't push the fluid in a system like that, because when the fluid hits the second manifold, it is going to try and push the fluid back into the other intakes. You need to pull the fluid, and drop it into a reservoir so it can be pulled back through the system again. Naturally, some runs that are easier are going to flow more, so you will have to test the flow for each. Also, would be a good idea to pull the fluid out in smaller manifolds, each with their own pumps, and own reservoir.
@randoedits6906 Рік тому
Nah they don't need to do all that. Their problem is a circulator pump makes no head pressure, raise the pump above the system and it will cancel out the head pressure created by gravity, also each 90elbow fitting will add at least .5 psi to the head pressure (they have like 30 of them as each nipple on the manifold changes the direction of flow) and they have like 30ft+ of pipe which will also add friction increasing the head requirement. This pump is a circulator pump that likely doesn't make more the 5ft of head pressure, probably .5ft to 1ft as it was meant to circulate in a small closed system, not a monstrosity that is feet above the discharge of the pump lol.

I feel like in a previous video, it was established that if you want to do this, you should first run the hot water through a radiator to get the temperature down for most of the way and then run it past the TECs to go sub-ambient.
@indigenous.rabbit2877 Рік тому
I believe you ran the cooling to the peltiers in parallel, that would completely explain why the coolant was not getting there. Water always takes the easiest route so there was no need for it to go through the top ones, it could just go through the bottom ones. Also rethink the diameter or your water tubes, the tubes going to the waterblocks were really thick and the one going to the pumps was only a little thicker. No wonder there was almost no flow in some areas. You would probably be fine with those flimsy 5mm ish tubes going to the individual units on the hot side. Maybe for a second iteration of this split the cooling system up into groups of like 4 peltiers cooled in series with smaller separate radiators. Also have the water in the cold loop flow the other direction from that in the hot loop to make sure the water doesn't get reheated by the higher temperature peltiers (because they are in series the last one gets a lot warmer cooling water and thus will cool less far on the cold side). I think by hooking up the cold side in groups of 4 (or so) with their own pump and combining the output with a splitter to the CPU plus the aforementioned changes you could optimize this setup.

For a manifolded assembly like that you want it to be horizontal rather than vertical so gravity affects each one the same. Then you can have radiators attached to the hot side drawing cool air from the cold tubes on the bottom and the cold side blowing chilled air over the hot tubes on top for a small performance boost in the setup.

1. Use a few distribution blocks (eg Phoenix PTFIX) instead of soldering 80 wires. Or good old Wagos. You'll hate yourself less. 2. I would do a 5s4p connection instead of 20p to save on tubing effort while having some redundancy. E: any manifold connection has potential for unequal flow so you need to watch out for that. Big benefit of series tubing is you have the same flow rate everywhere.

@todorow22 Рік тому
He could tune the flow rates with flow controls. reducing flow in the lower peltier devices would probably balance the flow up to the peltier devices that are much higher and thus need more head pressure. If you are feeding the same head pressure to each row the top will never get good flow.

i think you might get better results if you use a large high reservoir above each loop and let the pumps just pump the liquids up, then let gravity let the liquids flow through the coolers this would probably get equal flow through each cooling element. that way you could also store some cold liquid in the reservoir and run a benchmark from the stored cooling capacity of the reservoir.

@eduardocarrasco8830 Рік тому
Alex, the way you connected the pumps is not giving you double the head pressure, you are basically connecting them in tandem. This mean that one pump discharges just to feed the suction tank to the next. There is not pressure transmission doing that, so basically is just the last pump working, the first is just feeding the second tank, that’s it. If you want to connect the pumps in series to double the head pressure you need to connect directly the discharge side of pump 1 to the inlet side of pump 2. If you want to double the flow, then both pumps must be connected to a discharge pipe at the same time, but the total head is equivalent to one pump.

You gotta connect those blocks on the peltier-s in parallel (at least in blocks). You could do four groups of TEC-s with each group having their own pump and radiator combo so you have higher crossection for the water to flow through. If you connected everything here in series, I would imagine, the pressure needed to push the coolant through the whole system is too much with just a tubes diameter of cross section for coolant flow.

You have to create strings and parallel streams with your cooling liquid. The way have it now you would need an open reservoir which presents NO pressure at all. Best way to to this would be to have the water coming from top into the reservoir like a small waterfall. With that much parallel water flow you actually hampered the whole performance. Also add some automatic air reliefs at the top to get the air out as fast as possible. We have the same concept in out town water system where I'm responsible of. You need strings and parallel flow correctly done or else you have no flow at all...

Also these peltier things are horribly inefficient at full power tech ingredients did a video using these to create a freezer and fridge really cool vids i highly recommend watching them (as well as the ones alex mentions in this video) if this kind of tech is truly interesting to you. Awesome video! I would honestly watch a whole channel dedicated to alex doing random stuff like this.

Honestly, I love these types of videos, even if the result doesn't exactly pan out! Sometimes you get a wild and crazy result, and we all benefit by learning!

@AKOsiMORRIS Рік тому
from how I understand piping in general (I am not an expert) the reason there is so much air trapped is because they don't have any pressure release valve located on the highest point of the loop so the air just gets trapped on whichever place gets the water flow last... it's basically a one-way valve that traps liquid below it while release any air upwards without giving it a chance to get back into the loop (I think the show The Good Doctor made a decent demonstration of this)
@kylepawlaczyk6293 Рік тому
It is not just a pressure issue, it is a flow issue too! You need to assess the temperature drop of the coolers and then use Q = M.C.DT to work out the total flow required.... then assess the flow of the pumps against the head pressure of the assembly.....

I love these engineering videos. Please keep them going in any way you can.

I'm here for more of Alex's off-the-wall cooling ideas! As in, he comes up with the ideas by "throwing shit at the wall to see what sticks", then makes videos out of what does /not/ stick.
@RabterPlaying Рік тому
You need to put the pumps in parallel to get a higher flow rate. You dont need more pressure you need a high flow rate to feed all the tubes. Since there are so many tubes in parallel the pressure is instantly dropping (because of the low flow rate) thus not reaching the top. What also would help is mounting the pumps on the top so the pump is higher than the rack

We are slowly getting to a point, where our CPU coolers will need their own coolers.
@Exilir8 Рік тому
@Ahmed Jones but If we get a cooler for the CPU cooler's cooler, then we'd also need another cooler for the cooler for the CPU cooler's cooler.
@ColeRees Рік тому
I can’t believe you guys are doing ANOTHER peltier cooler video right as I’m designing a stupidly crazy design for a giant observatory telescope chilling system. So thankful!!
@Running_Wakko Рік тому
Please don't use Alex as a starting point. He is making so many stupid mistakes. Main stupid thing was that he did not place the header tank on the top of the loop.
@ColeRees Рік тому
@@Running_Wakko don’t worry, we aren’t using this is a guide! Our system is going to be far more complex as it has to work in all orientations. The water blocks will be changing orientation as the telescope mirror moves around, so we have to account for everything. We’re gonna build a working model before we even try out the real thing.
@pwnzcrewgaming Рік тому
to prevent bubbling and air lock, I would have put the pumps & res above the circulation loop height instead of trying to pump and maintain fluid pressure up-hill into the loop, Great build though Monster cooling setup, very awesome!
@matthewfaithfull1893 Рік тому
I built one of these for real and fitted it in a case last year. 380W and 46900 in CB23, 3970X 6900XT, 7 TECs, 3000W of PSU.
@fvckyoutubescensorshipandt2718 Рік тому
I think my Prometia cooler only drew like 800w and could keep a 500W load at -20C. I just got tired of dealing with condensation, so went with water chiller that keeps the loop at 1C above ambient.

@RTDragonCommando Рік тому
I think the pumps needed to be split up among the different sets of coolers, so a pump and a "one in five out" manifold per level of that tower. Getting the water/coolant to cycle properly through all the blocks would probably make a huge difference, and if I understand how they work correctly, may actually get the TECs to draw more power. The reason for that being they have temperature limits on the hot side, once it reaches a certain point it just can't push more heat across, and will drop off.
@deidyomega Рік тому
Those tecs need 17v, they were giving them 12v. So the devices were underpowered, thus under delivering.
@chrols1 Рік тому
love alex's strange, wierd and amazing cooling ideas! best one yet!
@Bangie Рік тому
Do a version 2 of this cooling idea! More optimized, compact, make a frame or something so it can be used for future overclocking videos. Put it all in a box that can be transported around etc
@seanthenry Рік тому
Run the coolers in series and not parallel, that would simplify the lines and reduce the total liquid needed.
@upholsteredhero5216 Рік тому
The way you do this is to buy larger water blocks. You can get blocks that are longer so that you can attach 4x or even 8x pet's per block. The correct way to do it is to add a pet inline wired up to an inverted furnace thermostate so that you can temp controle power on and off the pet's. Best way to go sub ambiant is with geo thermal heat sinking though. Your coolant should stay a constant inline temp between 10-15 degrees. Heres is another hint people condensation requires a temp differential based on humidity in the air. So if your pc was in an airtight humidity controlled enviroment like a mineral oil case or a freezer you can eliminate the opertunity for condensation to occur.
@KuramaKitsune1 Рік тому
Should have had those tec modules in series and parallel behind each other cooling the hot side of the other tecs for a multi-stage
@Zephyruxs Рік тому
alex is easily my favorite person to see leading a project
@AlistairBroomhead Рік тому
I'd be interested in seeing what happens if you can attach 4 peltier coolers to the CPU via a vapour chamber and then run an open loop with a 360 rad for each. That should be about 340W of cooling with a much simpler setup (no loop on the cold side, only 4 blocks and rads on the hot side). I'd think that the vapour chamber should help reduce condensation on the socket, as IIRC it becomes less efficient at lower temperatures, helping to keep equilibrium somewhere around or above ambient?
@Dukes3677 Рік тому
Jake getting sprayed after asking if he can just crack it real quick had me cackling
@crazzywolfie Рік тому
i think you should try improving this. you should mount the pump/reservoir up high to prevent air lock and pressure issues if you want to keep testing the in parallel like you are. i would recommend each row of coolers in series and then have the rows connected in parallel. it would really force the coolant to circulate through the coolers and likely require less force and make the water much cooler.
@amiryousefi5374 Рік тому
actually u just write my toughts 😅😅😅
@tobiasjames6949 Рік тому
Exactly, never understood why most liquid cooling setups in typical computers have the res down lower either, should be the highest point - even higher than the rad - makes it much easier and would automatically deaerate
@jessery475 Рік тому
Peak Alex. Best addition to the team. Been watching since the days of just Linus and luke and having Alex onboard feels like a breath of fresh air.

I helped write the book on Peltier cooling back in the day chasing the 3ghz overclock of the Barton single core chips, it was a 240w arrangement that saw my name belated on the scoreboard and it lasted a week too, crazy thing it was a 1700M AMD rated at half the 3.1ghz I melted out the poor thing. I had two independent water systems running with the Peltier attached to a sandwich block then two water blocks and all built into the epic Antec Skeleton I had customised sprayed toxic green with blood spatter and more UV lighting you could shake a stick at hehe What made the difference was the DFI Lanparty boards which allowed you to up CPU volts but hold back ram and PCI volts which was the bane of the overclock, locking the PCI and RAM volts mean't you didn't murder your video card and ram and I taught both XFX and OCZ the wise thinking of having too open a lifetime warranty with both companies on the nth exchange of murdered ram and vid cards that they would not honour any further warranty claims after this final one... Sadly at the end of the week long fun, everything just cratered out, cpu, board, ram, the only thing working still was the HDD and PSU, still got the bits in a box somewhere with a tub full of melted AMD cpu's and burnt out Peltier's.
@skogach Рік тому
You could scale down this system to 2-5 peltier elements add a thermal sensor to monitor cold water temperature and use something like an arduino to turn on and off the elements to keep temperature just above the dew point. Then you could use one power supply and fit it neatly inside the case. This config can potentially be used indefinitely as a viable cooling solution.

Only time I've used a peltier was for a DIY dehumidifier, they're terribly ineficient, just don't use them.

Having them all be at least 2 in series would make the flow massively more uniform.
