Cooling An AIO with ANOTHER AIO

Have you ever wondered if it was possible to cooler a CPU cooler with another CPU cooler, Probably not but thats not the point. I like to answer the questions your didnt know you had, so i decided to take and AIO and try to cooler another AIO with it just because it was fun.

Yay I was right! Though I thought you'd just put the ice inside of the "cooling tower" or even just on top of the radiator. If you still want to follow your dry ice idea, you could make an open loop with two cpu blocks and no radiators at all, and try it that way. It should be a bit more efficient.

[@davidr0013]

I was going to ask to do a double cpu block, but you beat me to it.

[@beauregardslim1914]

I agree. Two CPU blocks, a pump, and just the dry ice hopper. Unfortunately that will mean using custom-loop components or disassembling AIOs. Don't freeze your coolant. Seal your hopper with paint or epoxy.

[@sarme5044]

Use acetone in the container with the dry ice. It'll optimize the heat transfer from the block and it won't freeze. Although, with the way that thing was leaking....

[@1991apfel]

Also mount a radiator on the Block to increase the surface.

[@MajorHardware]

No problem if you ever think of something that u think is way out there let me know I'll probably give it a shot

[@bikerboy3k]

@@MajorHardware Sounds great. One of the things i keep thinking about is to apply somehow the principle of automobiles intercoolers to pc cooling. If not efficient, at least will make for a badass experiment in engineering. So i was thinking given how an intercooler cools air down and cool air occupies less space than warm air, you can jam more of it into cylinders which means more fuel mix overall=bigger explosion=better performance. What you did here in this video to be fair is kinda that let's be frank, in terms of heat exchange. But still, i don't know, just throwing it out there. Maybe to add another radiator with a fan on it between cpu and the main aio radiator?. To use maybe an eclectric motor to suck air into a radiator with a fan on it, and then use a pump to force that cold air into an encasement for a cpu air cooler with another method of sucking the air out and re-circulating it again into a radiator for cooling or maybe just exhaust it away ? Or to use the exhaust heat to power a small stirling engine type of mechanism that now will also aid the main pump to push in even more air ? This is all stupid stuff bred from a bored mind-again dude. I am really interested in the application of mechanical means of cooling i will be honest. The noisier the better. it's just something quirky i personally think would be-like i said- at least a nice experiment in engineering. Thanks for taking interest and proposing i shoot an idea. Very nice of you. All the best brother.

[@first-thoughtgiver-of-will2456]

This is very helpful information for my current project thank you! I am creating a very similar design (I shared in a previous videos comment the BOM rough draft). I am using atomizing emitters by setting the diameter of the emitters to 0.4 (or less-- work in progress) and creating as many as necessary to equate my tube's inner diameter. Atomizing emitters should increase the drip surface area and maximize evaporation of relatively hot particles, possibly at the cost of extra water due to mobilizing cold particles as well given airflow. The equation: tube_area = n*pi*(0.2)^2 where n is the number of emitters to solve for given tube_area which is the cross section: pi*(tube_diameter/2)^2 If your water is colder than wet-bulb ambient temperature you will essentially warm the fluid and cool the ambient air.

[@Championjcc608]

TEC's are just not designed for it sadly. they're good at removing small amounts of heat in the long term.

[@TheHarleyEvans]

you need a larger thermal conduction plate at the cooling end, the problem is that the dry ice didn't have the surface area to efficiently cool the AIO loop, also it would be way more efficient to skip the cold loop altogether and the cooling tower, by placing the hot radiator in the bucket of dry ice

[@amon_san]

are AIOs directional in their hear transfer or does it work interchangeably in each direction? would attaching the cpu side of the second loop to the first loop radiator do you any good?

[@avrel820]

That was fun i enjoyed the video :-) I finally got RGB Fans..Corsair HD 120 /DF RGB Led series (Orang/pink/purple on the picture on the box)... Replaced the Aio rad fans with the corsair les fans so that it will light up the inside of my PC ( Aio rad is at the top). The original Fractal design fans now replace the front fans on my PC.. As my case is a Nzxt H440 the front fans cannot be seen as there is a front panel so i went for best easy option... Thanks to you i have RGB in my PC and it cools slightly better. Thanks :-)

[@MajorHardware]

Rgb makes everything better

[@TefenCa]

The outside of the radiator isn't meant to be wet with water. There is steel on the outside and usually copper/brass for the fins. Adding water will promote/cause galvanic corrosion. This test is obviously possible to do for short term but the device would not be good to use long term even if it worked well.

I wonder if 2 120s would have performed better? Half of the 240 being warm could be keeping the water from cooling off.

[@7236399]

well the tower cooling is a pretty good idea! use the dewpoint to your favor

[@TotoGeenen]

Can you make a custom loop with two cpu blocks and no radiator. Then hook up a cooler to the second cpu block. Could be an aio, a tower cooler or even a gpu cooler.

[@kosmonautazkambodzy3679]

Could do an experiment with water cooling where the pump and radiator are 5 m away from the block. I wonder what the temperature difference on the CPU will be.

[@anderssorenson9998]

I was way off I thought that you would have two rads pressed toghether push fans on the cold and pull on the hot, with chilled water circulating. In retrospect it would be a sub ambient system and fudge up the machine

[@MrGHOSTMAXX]

it would be neat to see some sort of tunnel that would holds dry ice and have a fan blow over it and into a air cooler

[@MajorHardware]

thats thinking with your dip stick jimmy ill keep that in mind

[@kadentstructuraldesign9929]

Seal off all of the external air and just have a fan inside the case blowing on the dry ice and circulating the chilled air

[@fromaflafl2198]

you cut definitely make it work. the main problem is the heat transfer from the dice to the cold plate is bad. and if you had an interface fluet like isopropanol it woot help immensely and make it work. but it woot properly be easier to just at the dice to the water. ore if you want some nice low temp make an open loop with at big res and youse ethanol as coolant and just drop the dice straight in the ress

[@jensL.]

You could try to switch around the radiator positions. Your current tower cools down the air inside the tower, befor cooling down the CPU radiator. If the CPU radiator was on top the water would give a little heat to the air inside the tower and fresh cold water from the pool would be pumped over the hot radiator.

[@MrBigZN323i]

remake your cooling tower to house the larger radiator with the water droppers dropping water directly onto the radiator and right at the top have a fan blowing down , this works great in industrial applications

I would be interested to see if two rads could be cooled by one fan. Imagine a 3D printed housing which aligns a rad, an air gap, and another rad, air sealed so only the outer rad fins are exposed. On top of that construction sits a 120mm or 140mm fan that pulls air through both rads into the air gap and outside of the housing. How would it perform and how noisy would such a solution be in comparison to a single rad?

[@mrdr9534]

@Major Hardware Thanks for another entertaining video, but I (like others in the comments) wondered why You didn't simply put the "dry Ice" directly into the water container ?? Best regards

[@ktmarvin300]

you could try using smaller pellets to increase the surface area of the dry ice which is in direct contact to the coldplate. Or (even better) use Isopropanol, if it doesn't dissolve 3D printed stuff. I'm pretty sure, that the reason why the system is not working is an unsufficient heat transfer rate between the coldplate and the dry ice.

[@marekhorak4453]

The good part is you have that big beach beer cooler ! Buy some cheep used small freezer and carefully dismantle that internal freezing rad,without braking any pipes, and submerge it in to the antifreeze liquid poured in to that big cooler. Than just place that CL rad in it and use that small pump to circulate that antifreeze. Turn it on,adjust the temps, and enjoy. Give dry ice to kids to play with. Lol

[@RawSiafu]

Try a pressure pump with some mister nozzles similar to what is used for aeroponics or patio misting. Misting nozzles with smaller orifice maybe better cooling. Put inside a tower a few feet high with some good air flow through the mist. Can use multiple nozzles up the tower and reservoir collects at the bottom. I setup aeroponics in some 4" diameter PVC pipes tower (round and square) about 10 feet high and the water would get very cool and last a long time without a refill needed. I had a bucket at the bottom for the reservoir. Tower was put through a hole in the bucket lid. Simpler way is you could also just use 1 sealed bucket with a couple of holes in the lid for the mister/pump hose. Bucket can be quarter full and spray into the bucket. Anyway the point is the mister gives good surface area on the water to cool.

[@flyingunderwear]

Remember, everything in the chain needs to be able to dissipate the heat of the components before it. The cpu is obvious, the pump in the aio will add heat, the pump in the cooling tower will add some, tge pump in the other aio. Ect ect. If you want to get the "cold" out of the dry ice you are going to need a pot like they use in extreme overclocking and your choice of fluid with an extremely low freezing point. It's all about contact with the dry ice. I'm sure you've seen the equipment they use in dry ice overclocking.

[@AlexMullerSA]

What about a big custom cpu block that you can attatch two AIO to co cool?

[@emancesooh]

Take a 240 rad and cool it with water instead of air/fans. Use evaporating the water from the reservoir as an evaporative cooler for the room. Increase the flow of water passing through the cooler and have a couple gallons of water that it's able to go through and a fan blowing across that water. Sure water will evaporate away... But you could actually cool the room and cool the CPU... Everyone needs more humidity in the winter anyways! If you want to incorporate dry ice still, you could use it best to make a condenser on top of the reservoir that recycles water/humidity back into the system. Be the hero we need! ;)

[@oscarcharliezulu]

So what I’d like to know is can you chain 2 x 120/140 2 AIO is series

[@ChrisGR93_TxS]

You could just cool the radiator with flowing water... that was my first thought.... or with air&water(evaporative cooling) flow to take advantage the evaporation and desapate heat from the fins faster. Like big companies do to cool down their server rooms.

[@oliverscorsim]

I really wanna see methanol with dry ice as the cooling fluid it's what we do on race cars for intercoolers gets the intake temps under zero

[@vanebooo5134]

You sould try to design and make a waterpump for pc with a fan motor.

[@richh9570]

The noise was your pump on the radiator burning up. If you flip the radiator so the hoses face down, you would avoid that problem. Would also cool better

[@k1e1v1i1n]

BEST PROJECT EVER,

[@HardwareHorizon]

You should try Evaporative cooling. You'd need to have water trickle down the fins, then use a fan to push air across the water. As the water evaporates, it pulls heat from the radiator into the air. That said, you'll always have to refill the reservoir, but it could be a fun experiment to try.

[@newlinedetails]

I would try submerging both radiators in 1 pool of water. Have the pump pull the water across both of them.

[@kmemz]

Instead of cooling an AIO with an AIO, what if you took advantage of the cooling effect that water gets from the drip effect? Make the tower much taller (make it into multiple slot-together pieces perhaps?), remove one of the radiator slots, probably get a more powerful pump that can push water three or four feet up vertically, and see if the water can be drip-cooled with a few fan slots to keep the air fresh. I remember seeing serveral mentions of drip-cool solutions as an exotic form of cooling capable of minor sub-ambient operation once upon a time, but I'm curious if you can adapt it from what you showed off here.

[@GeneralLeeIrritable]

[@woodysgaming1294]

The water is passing through both radiators to fast. You need to get the water to stay around the cooling radiator a little longer so it can get to a colder temp before it hits the cpu cooler

[@lekmannen9990]

It would be fun to see you put a fan ,with dry ice in front of it, that blasts cold air on the water coming from the ”showerhead”

[@ArtosDeDraconum]

Submerge the 240mm rad in an antifreeze solution, use the tiny pump to circulate that anti-freeze and introduce the dry ice to the antifreeze solution to directly chill the fluid around the radiator, and let the AIO take that chilled fluid inside the radiator and circulate it to the CPU. This is the way.

[@needforsuv]

most complicated setup: put two radiators together and run water over them one rad/AIO goes to the cpu and the other goes to the largest (non heatpipe?) air cooler thats mounted back to back to the 'cooling' aio and you removed heat from the air cooler at the end or add coolness so it's an (air)cooled 'water'cooled-cooled AIO

[@hellureitaalla5224]

Id say benefit lf customloop is better than aircooling at cooling but what aio is actually meaningfully better than noctua d15?

[@metaleater9]

Here's an interesting idea, Mate 2 copper CPU blocks together face to face and use it as a heat exchange between two cooling loops such as an internal and external system. There are niche practical benefits and uses but most people will just use this idea to run a parallel loop for the different color liquids but without most of the cooling performance loss.

[@yazmo109]

this could be working , if you submerge the entire cooler. or have the water drop on the entire rad. give it a try REV 2.0 xD i luv these videos

[@SergeyPupkoMusic]

This is similar to putting the cold plate on the CPU without adding thermal paste. The contact between ice and cold plate is imperfect and the conductivity is minimal at best so you're getting little to no heat transfer... Or, I guess, in this case, cold transfer, since you're trying to transfer the cold from the ice into the cold plate of the cooling block. Not a wasted effort though, at least we know it doesn't work (at least in this configuration. :)

[@madjimms]

Should have just put the dry ice into the water so the surface area for cooling is greatly increased. Trying to get dry ice to sit flush on a flat surface isn't very effective.

[@dirkryan5962]

an alternative solution could be like the large, thin, flat custom PC case (link below) that another KZbinr (DIY Perks) made. his system uses water-cooled heatsinks w/ 2 large radiators. it's actually rather large (approximately 10" x 30" x 30"), but since it attaches vertically to the wall, it really doesn't take up any useable space. and because he made it w/ wheels and even fabricated an external port hub (USB, HDMI, headphones, mic, etc.) which connects to the computer using a custom single-line connector he made, surprisingly, it's rather easy to transport. plus, it's excellent for overclocking and is _essentially_ silent. btw, i apologize if it seems like i'm trying to one-up your idea. over the years, i too have thought a lot about different ways to cool a computer, and when i saw that custom wall-hugging system, i was blown away by it (because i really never considered just making the case bigger and thinner, but in such a way that it's still easy to move). perhaps you could do a video of you adding your own touches to a similar build. my new--videos-notification is set, and i look forward to seeing what you do!

before you reach for the hot glue, try plumber's tape on the pump connection

[@Dvantways]

Get a small fish tank fill it with oil then strap the two rads together with a fan between. And replace the hopper with a glass of dry ice and isopropyl alcohol (both have a -40 and -43 degree freeze point)

[@dirzz]

One crazy idea that I have is what if you could cool your CPU without the heatsink directly by liquid. Like if you could glue some sort of a funnel on top of a CPU and push water through it like you would with normal liquid cooler. It'll be pretty easy to fry your PC with a leak on that one, but if you use distilled water instead I think it could be more or less safe :)

[@H3adcrash]

"Now that I have your attention" Nu uh! Still focusing on the doggo! :D

[@Evoluzione069]

Problem you have is surface area only the edges of the dry ice are touching the block you need to add a liquid to act like a thermal compound on a cup to give better heat transfer as other people have said using acetone would do that but then your over complicating the process. You would be best dunking the aio from the cpu into a liquid with the dry ice to directly chill the radiator

[@kiklop8362]

Man, get an AIO what can be opened, disconnect the radiator from AIO and put one hose to shower head and the other one to the bottom of your cube. You will have much better heat transfer to the watter. And use alcohol / aceton with dry ice. But this idea works, I put one extra CPU block to my custom loop for fun and use snow to help cooling it. The problem was that snow was melting so fast and water was all over my table :)

[@MARTINREN1231]

My CPU is air cooled (ID Cooling SE 207) and my GPU is watercooled (An RX 580 with ID Cooling Frostflow 120VGA) I got these 2 since they are cheap and works really well. got the CPU cooler for about $40 and the gpu cooler for $33. My overclocked Ryzen 5 3600(4.3 Ghz all core) is at most about 75C and the gpu (Core: 1.45Ghz and memory at 2.1 Ghz) is at most about 65C

[@TefenCa]

1 major problem with anything trying to involve sub-ambient cooling is that you need to insulate everything very well to keep heat energy from getting into the cold loop/parts. The whole box full of water etc. is absorbing heat energy from the room and warming the water up. That would need to be insulated properly for it to work any better. ^_-

[@abdelrahmaneweis107]

if you wanted better results you should have turned on the pump of the 120 aio (top one) to transfer the cooling of the dry ice faster
