3:55 Pro-Tip: When draining a closed liquid loop, open an air-intake near the top of the loop before opening the drain port. It'll drain faster, and flow more smoothly. By "more smoothly", I mean you will avoid the -glug glug glug- type of flow that causes the stream to alternate between gushing and dribbling as it allows air to enter through the same hole the liquid is trying to exit from.
Not just a PC tip, any closed liquid system that has more than one possible opening. Great tip when you're changing your car's oil for example, open up the fill cap up top, then the plug on bottom.
@@askmeaboutmyscrotum3527 That was only removed after the cut, and at that point the pc was almost dry. We never actually see it drain with that cap off and a sizeable amount of liquid in it. I cant believe I had to point that out.
I love how everyone on this channel is supremely gifted in their knowledge of how computers work, but are some of the clumsiest human being on the planet.
@Tyler Perhaps ‘gifted’ wasn’t the most correct term to use. I simply mean that they are very knowledgeable about computers and tech in general. Far beyond that of the average person, at least. But that wasn’t even really the point of my post. I just find it amusing that people extremely skilled in one area can be lacking in another, seemingly simpler area. It does make for more entertaining videos though.
Yeah it turns out that thermal conductivity doesn't matter for a transfer fluid that much. The thermal conductivity mainly comes from the metal waterblock, which can be enlarged or shrunk quite easily to have better heat exchange with water. What is needed is thermal capacity in the water to soak up more heat, or a bigger pump. If you'd want any reasonable increase in performance and have thesame tubing and waterblock setup, you'd need to swap the liquid out to ammonia.
Why ammonia? I mean, yea, if you turn the whole thing into a refrigeration cycle that would do, but as a liquid ammonia has about half of water's heat capacity. Actually, water is just about the best medium for heat transfer between 280 and 400-ish K you can find. Nothing (I know) beats its heat capacity. You're right in that a larger pump would likely help out more just because it helps with the temperature gradient in the block. However, I suspect the bottleneck in this particular system is the water/air transfer, mostly because it always is. In fact, the higher conductivity liquid would probably show the largest improvement in settings where the pump is severely undersized. Any flowing liquid will form what's referred to as a "boundary layer" on solid surfaces, which is essentially a stationary film that heat must pass through by conduction rather than convection. This boundary layer is thicker when the flow velocity is lower.
@@misterjonas6991 About the heat capcity of water being higher? Depending on the temperature, ammonia has a higher heat capacity per litre. It defenately has higher heat capacity, but it's less dense. Point is, you don't really have to care about heat transfer that much if you're cooling to such extreme colds.
A 1% graphene addition to cooling fluid increases thermal conductivity by 61% and reduces viscosity by 31%. Note: is really only useful at high flow rates to give benefits over other coolants as it absorbs/dissipates heat quicker, but has identical heat capacity. What we would have needed to see in this test, is a high-flow pump setup, as you don't get the max benefits until you hit around 6L/m flowrate to take advantage of the increased thermal conductivity of the fluid. In addition, you could probably use a single pass high flow radiator for increased performance with this fluid with its higher heat transfer rate, instead of the 2 pass rad installed.
I agree, I enjoy Linus and other staff too, but Alex has a calm light-hearted demeanor about him that makes his videos feel like a breath of fresh air!
Der8auer already did thermal testing, about 2K less temperature, so quite within the margin of error. I assume you would need much more graphene particles to get a decent effect, but then you would probably have to change the naming from water cooling to syrup cooling or something like that.
The only way to improve on water is with a fluid that has more thermal capacity not thermal conductivity. Thermal conductivity is how air coolers work.
@@Mrx1080 water already has an enormous heat capacity. But it's all meaningless if you don't get rid of it fast enough (unless you have a massive reservoir, then maybe)
not really, this isnt the type of foaming they are meant to prevent, i made a post apart, the liquid is meant to prevent cavitation bubbles, these are bubbles that generate due to the drop in pressure in certain parts of the pump, they are an issue because when the pressure rises back up they will implode, and the incoming pressure of the liquid will be like the tiniest pistol shot ever, ohh so slightly eroding the surface in which the cavitation bubble had happened.
@@revdarian That's a good point, but i think those would form from shaking a bottle aswell. Though I'm not sure about that. Maybe for the cavitation bubbles to form you would have to hit the top of the bottle (lightly) with a hammer. Like when you hit a glass bottle on the top and the bottom pops off due to cavitation. Imho still slightly easier than Alex's drill method.
What did they say about the resistance across a little distance of coolant ? I would have thought graphene would act as wires if it really changed the water? I think its such a tiny amount added to make it go black,that the electrical conducivy didn't change much. The fluid will just be glycerine or something, which will just boost specific heat a bit... Or its the antifoaming agent only making a change?
That is actually interesting, the water must somehow get less conductive (unless its just clogged but im ignoring that) I cant remember off the top of my head what it could be, but it has to be something
@@defiantgg1831 I think it’s just impurities that it collects overtime. Or having it heat up & cool down over & over. Somehow changes the water, everything is clean. Fans & rad. No dust ect but my water always goes up 5-6c noticeably over time. I just put it down to impurities within the water that’s it’s gathered from the loop. Could just be micro impurities but enough to change the temps. Wouldn’t know without a microscope & comparing. The used water with new liquid.
@@Near2Future might be some of the particles of whatever is in the water, since there is still some even in distilled water that gathers, and blocks/slows down the flow or something im not at all sure, but its possible
The anti-foamer may be doing something, we don't know what their solution did without it, could be much worse. Also, I'd be afraid of the graphine buildup in the block and radiator.
I mean, technically speaking as long as the graphene doesn't completely block the flow it is conductive, so its not like it'd be a problem even if it coated it up since it would still transmit heat through itself.
@@Adierit Im starting to think thats exactly what needs to happen in order for it to work even better. A graphene tunnel where the water pushes the thermal load
also suspended particles will stick to the boundaries between the liquid and gas phase and reinforce the bubble boundary so therefore ensure the bubbles stay around for much longer, but if you overdose the suspended particles it can have opposite effect and just shred bubble formation
@@Adierit Theoretically a very small amount of buildup along the radiators would probably increase performance. Better thermal transfer rate material touching a larger amount of liquid to dissipate heat.
@@ImOnyxRS I don't buy it. Normally your heat flow would go from copper cold plate to water directly. You're saying adding another (imperfect) thermal interface would improve it? So the heat would go from copper to coated graphene particles to water. There's no way that's better, especially since the coating will be nonmetallic.
@@christopherjc54 As a Chemist, I'd say you'd have to re-engineer not only the fluid, but also the cooling setup. A more volatile fluid is better at taking heat away, but it comes with a whole lot of problems itself. A denser fluid can also improve thermal conductivity with the same nanoparticles, but I wouldn't be sure if that could make the trick.
As an automotive engineer; I'd say if you re-engineer the cooling system you can get pretty much any cooling power you'd want with regular old tap water. No need for any carbon dirt.
@@Nevir202 And you would be absolutely right about that my good sir. There are several other properties that will impact the overall heat transfer, but the material properties of the particles and fluid impact it the most.
"Bring in the engineers!" Two guys show up; one is exactly what you'd expect an engineer to look like, the other looks like he's there to take the first guy's lunch money, girlfriend, and job

"We recommend flushing the system of your previous coolant with de-ionised water before adding Go Chiller for maximum performance." Theirs a notice to flush the system, idk if that was done, or would alter the testing, Im bigggg interested in this coolant for 3 loops based off the color profile.
It would make sense, if the liquid were ionized I suppose you would expect the nano particles to align in direction, and preventing an optimal randomized directionality in the particles.
“Graphene has been discovered in 2004 and been theorized to do… everything… well except leaving the lab” That was gold Edit: thanks for all of your likes I didnt expect it🤣
@@Skylancer727 I dont know.. i ran mayhams nano fluid for 2½ years and there was no build up in the blocks.. it had a little in the pump but not that bad.. if its anything like PRIMO CHILL VUE then its bad.. How ever Graphite is a lubricant. so it might work out OK
agreed. Would somebody need to build a system designed to keep the fluid agitated by keeping it moving quickly and not having many horizontal lengths of tubing? What happens if it does settle, can it be re emulsified?
this one time i mixed two different mouth washes one was green one was purple. it made this very strange reaction where it was iridescent and constantly flowing all throughout it even days later. i've never replicated that but i'd love to see something like that in a coolant. seeing the turbulence in the water looks so sweet
This video was amazing. Typical LTT shenanigans, making an absolute mess. Also really appreciate that you got the engineers in, and re-ran the test as you weren't happy. (Glad you did the complex system too though, as it looked sick!) Also "I have my highly technical, little agitator here. Normally Linus is good but he's on vacation unfortunately." - May be the best LTT joke ever.
I'd love to see the long term results with using this for a few months and if any issues come up. I can't shake the feeling that it'll gunk up components over extended periods of time. Hopefully I'm wrong. Because it DOES look cool in a custom loop.
Graphene's hardness is pretty low so optimistically it won't grind up components, while graphene is electrically conductive it seems the suspension limits that to something similar to salty water or comparable cooling solutions. My only worry is it clogging up the impeller in the pump or the micro-fins in the cooling element since it seems to only barely be in suspension. A longer-term test would be great to see because it does look amazing even if you ignore the marginal cooling efficiency improvements.
I wonder how the graphene particles affect the inside of the tubes and pump over time... Like does it scratch up/cut the inside of soft, hard plastic or rubber tubing?
@@honeybadger6275 yeah i don’t even give a damn about its „superior performance“ either. Just call it fancy coolant and people would still buy it all I’m concerned about is that stuff coming out of suspension literally everywhere constantly and forcing me to clean out every single component of my loop regularly cause that’d just be much more of a pain than fancy looking coolant is really worth to me
I would expect a greater effect if smaller radiators were used. The pump speed also plays a role, why didn't you try to test low, medium and high speeds?
the speed of the coolant negligibly effects heat transfer unless you slow it way, way down. you're the first person to make the correct assumption that a smaller radiator would have shown a greater effect though.
the issue is the temperature delta. In a car the coolant is around 100c (212f), and ambient air is going to be, let's say 25c (or 77f). That's a 75c (165f) difference between the coolant and the air you are trying to dissipate heat into. In a watercooled rig what's the delta between coolant temp and ambient? 10, may 15c (50-59f)? There's just not all that much improvement to be had from the coolant itself. Even differences in the radiator itself are going to be minimal with those kinds of delta numbers. I'm sure water wetter would help, but the difference it will make is going to be very minimal. If we want to see significantly lower core temps, we need to either improve the thermal conductance of the die itself, or go sub ambient.
Iirc, the water-wetter helps by preventing localized boiling at hot spots in the engine block. If your die never gets near the boiling point of the coolant that's probably not benefit to you.
As the other comments say, I don't it will really do anything or something significant, but, "this is LTT!" (Read as in "this is Sparta!") So yeah! They should do that video Ltt style.
Water wetter will not make you engine run cooler, it raises the boiling point significantly so you can be safe at the high temps you see at the drag strip. IIRC it was meant to be added to engines running straight water. If you have antifreeze/coolant already it will do nothing they aren't already doing.
Seems like a very cool fluid! But im also very interested in a long term test vs. a „normal“ coolant to see if there is more or less abrasion on the coolers and if there is more or less residue from the particles falling out of solution. Evaporation-rate shouldn’t be significantly changed vs. normal coolant or distilled water and Evaporation-rate is also dependent on how airtight your loop is.
When comparing keep in mind your cryofuel was used. It would have picked up ions over it's life in the loop. Fresh fluid might be less conductive. Same goes with water, after a while of running in a loop it will pick up ions from the loop components.
I prefer the stock Noctua paste. Insanely good for paste (almost as good as liquid metal), and nearly impossible to fuck up. And it's free with your cooler!
The bigger your radiators are, the less temp-difference you'll see... It is better to invest in a bigger radiator. This kind of fluid is only useful if you have small radiators en high temps!
When he said "you don't want bubbles forming on the microfins", well for that, where would the air come from? On the contrary you actually want surfactants (tensides) in your liquid that would break the surface tension and allow it to flow around the microfins better; but tensides are literally dish soap, so at the surface, they can tend to form air bubbles. I also think a small amount of surfactant can help remove the air better wherever it can be in the loop. Maybe the resulting foaming can be disconcerting, so maybe they added tensides to improve performance, and added anti foaming agents to then make it... not foam over in the reservoir and not look so scary.
The graphene would have to come in contact with the walls for this to work effectively, the boundary layer of a flowing liquid should prevent most of that from happening.
So in other words the graphene does not do much except add a sort of liquid charcoal look. It IS is amazing looking though, very different from just a black fluid. If I has a water cooled PC I might even buy some, provided it does not clog the system up.
I guess the other stuff creating a coating around the graphene particles (as they guess in the conductivity part) doesn't help either. i guess all it really does is making the liquid look fancy and be wayyy more abrasive at the same time...
this is not correct at all, please do some research on nanofluids. the heat transfer mechanism is still up for debate but there are very concrete gains in conductivity with nanoparticle suspensions. that being said i would never put them in a pc cooler as suspension stability is the hardest part of the equation - an engineer with research experience in nanofluids.
I'd be curious to know what the specific heat capacity of the coolant is. I dont see the conductivity being a big deal, but instead how much energy it can hold and how hot it gets. I could see conductivity being a big deal on a heat pipe, but for water cooling you are just putting heat into the water at the block, then physically moving it to the radiator to offload it. If it holds more energy with less of a temperature rise it could be very interesting.
Thermal conductivity is everything in coolants. For reference watch this: th-cam.com/video/-SVYKeSKBhY/w-d-xo.html Short term you are right, the heat capacity will be more important as it will essentially offset the temperature increase by some time. For long running and heavy processes however, basically any coolant will absorb enough heat for its temperature to rise. The point then, is to be able to absorb as much as possible while near the hot parts and to off-load it while near the radiators. Since there's a flow the time each molecule has to absorb and radiate the heat is limited which is why thermal conductivity is important.
Like the previous commenter said, the thermal conductivity is a very important factor. In addition to absorbing heat more readily, it also disposes of heat more readily. This makes your entire system more efficient. The loop they did was very small, but I imagine in a larger loop, possibly with multiple radiators, this would have an even greater performance gain.
@@BL1zZ4Rth I have been digging around trying to find some stuff out, and the science gets really complex considering specific heat capacity, conductivity, viscosity, density, and I'd need to have a proper sit down with the science to get my head around it. It would certainly be interesting to see how the graphene infused coolant compares on the numbers though, especially considering that water has great properties as a coolant and most of the conventional options perform less well in terms of heat capacity and conductivity. I'll check out the link when I get a spare ten minutes and thanks for commenting. I really appreciate you commenting and making me think more deeply about the issue. Thanks
there is a company in Australia that has a process for refining graphene and is implementing it into things like mining buckets and other stuff, making the buckets last 6x longer than the original ones. It's a wonder material.
You may be referring to GMG. The have a graphene based product that coats the fins and makes HVAC 15-20% more efficient. They are also working on a killer aluminum ion battery impregnated into it's proprietary graphene.
Tried this stuff in my water cooled laptop build because it looks SICK. Within a week my dry break quick disconnects started to become less and less dry break. They never leaked but they went from next to no fluid coming out to needing to keep a paper towel on hand when moving the laptop because about .5ml would be coming out. Looked great but with how quickly it was gunking up the connectors I flushed it.
Coolant additives will never have much effect, the heat still has to conduct through a layer of water to get to the graphene particles. Heat capacity of the coolant also doesn't matter much if you can simply make the pump run faster. The limit is always conduction into and out of the fluid.
Actually, the limit is usually the radiator and heat transfer from liquid to metal to air. In my system, running the pump faster does literally nothing to temps. That's because there is already PLENTY of heat transfer into the liquid, but the radiator is the limiting factor. Most water-cooling loops would be the same - unless you have an enormous amount of radiators, it's the radiator capacity that limits the system
id like to say the anti foaming agent is required because they have to use a surfactant to keep the graphene from coming out of solution. surfactants are like soap latching onto the water and the dirt/graphene so it would foam up. comparing this fluid to how much water foams up isnt a fair comparison since it doesnt have a surfactant.
I don't see how it's not a fair comparison. They compared it to both distilled water and water with coolant in it. There's really not anything else to compare it to.

@@Dibromatic my point was that neither distilled water or a coolent with additives would need an antifoaming agent anyway. saying the anti foaming agent sucks because theres still foam in the fluid isnt fair because we dont know how foamy the fluid was before the anti foaming agent was added. imagine having a glass of soapy water and stiring it and theres millions of bubbles in it, now add a anti foaming agent and now theres a hundred. wow that anti foaming agent sucks because theres still foam? just no.
Well... Yes. Technically they should rephrase it into "this still foams more than [insert name here] but at least we all get the point. It's not the foaming agent's fault but the "problem" exists.
They also should've measured the temperature of the fluid at different parts of the system to see if the fluid was the bottleneck or the radiator (is the cpu/gpu not getting it hot enough or is it that the fluid entering the cpu/gpu is already pretty hot)
I didn't watch the vid, but there is a product called Water Wetter, for automobile cooling systems that actually does enhance cooling. A magazine test said 2 bottles, instead of the 1 recommend on the label, actually increased cooling. So, I bought a couple bottles and tried it. Sure enough my coolant temp dropped about 5C. During the summer, I ran mostly purified water with a couple bottles and it worked with typical coolant or plain water. I'm not sure how compatible it would be with pc liquid cooling parts and you'd have to refigure the rate of 2 bottles to 1 gallon of water for your reservoir, but the product did actually work.
That face his helper made when Alex said, "You are no longer needed" while seting up the second test bench. He thought for a second he was fired from the job ......
I'm guessing rather than vacation, Linus is busy helping his parents at the new cabin on their own island. Now that it has fast internet, he can take the kids and camp out there.
I continue to be fascinated by PC Water Cooling enthusiasts that seem to have no bloody idea how to drain or fill a system without making an enormous mess.
I wonder what happens to the fins on the pump after a few years of running what's effectively nano-scale blades of carbon? Also I would highly recommend against touching this stuff, being 1 atom thick, it could slice through anything from cell walls to DNA.
it isn't really just 1 atom think, it's multiple layers of 1 atom thickness. do you believe you'd be able to hold any sheet of 1 atom thick material in your hand like that without tearing it apart?
@@moos5221 It's a liquid. You can't hold it in your hand at all. Stop pretending the sheet he used for demonstration purposes is the fluid going through the pump.
Distrust ANYTHING that says "graphene" or "diamond" on the label... :) The main ingredients in that snake oil is most probably pulverized graphite and a suspension/dispersion agent. No "graphene" has ever been near that bottle :) Also, like with all dyes and additives - the real test is letting the system run for a year. My guess is that you can just as well throw that system in the bin after a year, one bad thing about highly conductive additives is that they bond like superglue to metals after long exposure :/
This. If it clogs your system, is abrasive or somehow solidifies over time you're better off with the old liquid. If not, it's selling point is pretty much "it looks interesting".
@@ragetist graphene is a lubricant, it is not abrasive. It wouldn't solidify, and it wouldn't clog because the particles are so small. It is 3-4 degrees cooler, so clearly its selling point is beyond "it looks interesting".

I'd want to see how it turns out looking after a few months of consistent usage before buying, but if that was good I'd definitely consider using this to build some sorta like dark matter themed build
Hey I noticed right from the start of your testing, you had introduced some major flaws. You said the micro graphene bits are what rapidly take hold of the heat from the CPU and then cools more rapidly in the radiator. One problem I noticed right from the first attempt, was that you never vigorously agitated the micro graphene bits into the GoChiller coolant liquid properly. You were leaving a huge amount of the graphene sludge particles in the bottoms of the containers. The test bed system, needed to be tested with water, then drained and dismantled to allow the water to evaporate or at least blown dry with compressed air. If you don't, then any residual water left behind in the rad or hoses, would have diluted the GoChiller and possibly even made it loose some of its coating properties. You also contaminated the GoChiller product, when you added it to the 1st PC which was full of that red coolant's sludge. To be thorough you should have added only brand new bottles of properly mixed GoChiller graphene, to a clean dried out PC for it to work at its full potential. It was very entertaining to watch, so keep up the awesome content.
Although what nobody mentioned was; you should, after you filled that graphene stuff in, let the system "always running" or rather - you shouldn't let it sit to long on its own.
I’d be curious as to what the graphene deposits look like after long term use in the microfins. The pump will remain well lubricated but I’m more curious of the deposition in the blocks. Then again it is curiosity more than anything as I am still a long way away from wanting a custom loop.
I'd be interested to see if any of the graphene settles out of solution while the PC sits for a while. With large reservoir pump combos I could see that being an issue where the graphene could build up and clog the pump.
You should do a long term (6months or so) of constant use with a heavy load put on for like 3-4 hours a day to see if the heat causes the graphine to solidify to cooling fins in a cpu/gpu water block and since its more viscous and heavier per millilitre than distilled water and see what wear/flow it does on the pump
Curious if the graphene in this liquid could also offer a potential lubricating effect on the pump or other parts of the system, judging from the lubricating properties of graphene and graphite.
I'm super curius if the distilled water or the other coolant impacts the black liquid. It almost seems to be separating. A nice clean and dry to start with test bench would be cool. Also hope the liquid used in the machines isn't the same in both tests to prevent contamination. Nice video thanks for making it!
They should've used carbon nanotubes instead of graphene, or something quantum. Artificial intelligence, blockchain and golden ratio would probably also help.
I can see that Alex is now improving in hosting videos thanks to talking what's in his mind rather than reading what's on the teleprompter and switch to a humanoid bot body language. I like it!
the most effective custom loop liquid is a rare formula called dihydrogen monoxide, with necessary additives of course. premixes that are just distilled water + additives are also valid.
The bubbles in the foam test were from you not using a clean tool every time. It's like mixing 2 different vehicle oils because of the residue on the tool, will foam 100% of the time.
With all sorts of unknowns about the chemistry of the "moss killing" and "anti-foaming" coolants, I wouldn't be handling them without skin protection and something that will definitely keep even tiny droplets from getting in my eyes, nose, or mouth. Yeesh!
Graphene might conduct heat better, but it's specific heat pales in comparison to pure water. However, you're never going to get a lower temperature than the environment. (entropy)

Have to say this title confused me, thought it was a cooler promising to keep your CPU at 7°c. Which seems impossible but dropping temps by 7°c seems like a more possible claim? *watches video*
Place a small, spirally bent wire into the drain, facing downwards (with a parabolic curve if you have the pipe sideways) and it should do the trick, just make sure the wire is somewhat same size as the drainage pipe. The draining stream should follow it.

3:55 Pro-Tip: When draining a closed liquid loop, open an air-intake near the top of the loop before opening the drain port. It'll drain faster, and flow more smoothly.
By "more smoothly", I mean you will avoid the -glug glug glug- type of flow that causes the stream to alternate between gushing and dribbling as it allows air to enter through the same hole the liquid is trying to exit from.
I was very surprised he didn't do that in the video.

Yeah it turns out that thermal conductivity doesn't matter for a transfer fluid that much. The thermal conductivity mainly comes from the metal waterblock, which can be enlarged or shrunk quite easily to have better heat exchange with water. What is needed is thermal capacity in the water to soak up more heat, or a bigger pump. If you'd want any reasonable increase in performance and have thesame tubing and waterblock setup, you'd need to swap the liquid out to ammonia.
And then your PC would smell GREAT
That's why I use my own piss as coolant
Why ammonia? I mean, yea, if you turn the whole thing into a refrigeration cycle that would do, but as a liquid ammonia has about half of water's heat capacity. Actually, water is just about the best medium for heat transfer between 280 and 400-ish K you can find. Nothing (I know) beats its heat capacity.
You're right in that a larger pump would likely help out more just because it helps with the temperature gradient in the block. However, I suspect the bottleneck in this particular system is the water/air transfer, mostly because it always is. In fact, the higher conductivity liquid would probably show the largest improvement in settings where the pump is severely undersized. Any flowing liquid will form what's referred to as a "boundary layer" on solid surfaces, which is essentially a stationary film that heat must pass through by conduction rather than convection. This boundary layer is thicker when the flow velocity is lower.
@@misterjonas6991 About the heat capcity of water being higher? Depending on the temperature, ammonia has a higher heat capacity per litre. It defenately has higher heat capacity, but it's less dense.
Point is, you don't really have to care about heat transfer that much if you're cooling to such extreme colds.
A 1% graphene addition to cooling fluid increases thermal conductivity by 61% and reduces viscosity by 31%. Note: is really only useful at high flow rates to give benefits over other coolants as it absorbs/dissipates heat quicker, but has identical heat capacity. What we would have needed to see in this test, is a high-flow pump setup, as you don't get the max benefits until you hit around 6L/m flowrate to take advantage of the increased thermal conductivity of the fluid. In addition, you could probably use a single pass high flow radiator for increased performance with this fluid with its higher heat transfer rate, instead of the 2 pass rad installed.

@@salluna1957 not significant contamination, but yes
👏👏👏 you did it.
not really, this isnt the type of foaming they are meant to prevent, i made a post apart, the liquid is meant to prevent cavitation bubbles, these are bubbles that generate due to the drop in pressure in certain parts of the pump, they are an issue because when the pressure rises back up they will implode, and the incoming pressure of the liquid will be like the tiniest pistol shot ever, ohh so slightly eroding the surface in which the cavitation bubble had happened.
@@revdarian That's a good point, but i think those would form from shaking a bottle aswell. Though I'm not sure about that. Maybe for the cavitation bubbles to form you would have to hit the top of the bottle (lightly) with a hammer. Like when you hit a glass bottle on the top and the bottom pops off due to cavitation. Imho still slightly easier than Alex's drill method.

What did they say about the resistance across a little distance of coolant ? I would have thought graphene would act as wires if it really changed the water? I think its such a tiny amount added to make it go black,that the electrical conducivy didn't change much. The fluid will just be glycerine or something, which will just boost specific heat a bit... Or its the antifoaming agent only making a change?

@@Near2Future might be some of the particles of whatever is in the water, since there is still some even in distilled water that gathers, and blocks/slows down the flow or something
im not at all sure, but its possible
its probably your thermal paste drying up.
The anti-foamer may be doing something, we don't know what their solution did without it, could be much worse. Also, I'd be afraid of the graphine buildup in the block and radiator.
I mean, technically speaking as long as the graphene doesn't completely block the flow it is conductive, so its not like it'd be a problem even if it coated it up since it would still transmit heat through itself.
@@Adierit Im starting to think thats exactly what needs to happen in order for it to work even better. A graphene tunnel where the water pushes the thermal load
also suspended particles will stick to the boundaries between the liquid and gas phase and reinforce the bubble boundary so therefore ensure the bubbles stay around for much longer, but if you overdose the suspended particles it can have opposite effect and just shred bubble formation
@@Adierit Theoretically a very small amount of buildup along the radiators would probably increase performance. Better thermal transfer rate material touching a larger amount of liquid to dissipate heat.
@@ImOnyxRS I don't buy it. Normally your heat flow would go from copper cold plate to water directly. You're saying adding another (imperfect) thermal interface would improve it? So the heat would go from copper to coated graphene particles to water.
There's no way that's better, especially since the coating will be nonmetallic.
Did my master thesis on this and yes depending on the ratio and the material suspend in the nanofluid this is entirely plausible.

@@christopherjc54 As a Chemist, I'd say you'd have to re-engineer not only the fluid, but also the cooling setup. A more volatile fluid is better at taking heat away, but it comes with a whole lot of problems itself.

As an automotive engineer; I'd say if you re-engineer the cooling system you can get pretty much any cooling power you'd want with regular old tap water. No need for any carbon dirt.
I would think though, that the compounds used to maintain suspension of the particles would be a bigger factor than the particles themselves, eh?

I can't shake the feeling that it'll gunk up components over extended periods of time.
Hopefully I'm wrong. Because it DOES look cool in a custom loop.
Yep will be pleasantly surprised if there isnt a major downside, from the universe's pain in the ass rules n laws.
It does look like the graphine comes out of the suspension pretty easily. Noticed it when he was pouring out of the glass into the fill port.
It may not sand down oxidized material the same way vue does. Depends on graphenes hardness I suppose.
of course!!!!!
Graphene's hardness is pretty low so optimistically it won't grind up components, while graphene is electrically conductive it seems the suspension limits that to something similar to salty water or comparable cooling solutions. My only worry is it clogging up the impeller in the pump or the micro-fins in the cooling element since it seems to only barely be in suspension. A longer-term test would be great to see because it does look amazing even if you ignore the marginal cooling efficiency improvements.
I wonder how the graphene particles affect the inside of the tubes and pump over time... Like does it scratch up/cut the inside of soft, hard plastic or rubber tubing?
Was wondering the same thing.
I imagine it doesn't. Graphite is used as a lubricant and graphene coatings are used for abrasion resistance.
I'd be more interested to see if it gunks up the microfins over time or if it foams up in the pump and kills that prematurely.
@@honeybadger6275 Exactly, 30 minute tests for a new type of liquid are almost useless.
@@honeybadger6275 yeah i don’t even give a damn about its „superior performance“ either.

I would expect a greater effect if smaller radiators were used. The pump speed also plays a role, why didn't you try to test low, medium and high speeds?
the speed of the coolant negligibly effects heat transfer unless you slow it way, way down. you're the first person to make the correct assumption that a smaller radiator would have shown a greater effect though.
Id like to see them try the automotive coolant additive called "water wetter", they claim up to 20°F cooler temps when used in a car.
the issue is the temperature delta. In a car the coolant is around 100c (212f), and ambient air is going to be, let's say 25c (or 77f). That's a 75c (165f) difference between the coolant and the air you are trying to dissipate heat into. In a watercooled rig what's the delta between coolant temp and ambient? 10, may 15c (50-59f)? There's just not all that much improvement to be had from the coolant itself. Even differences in the radiator itself are going to be minimal with those kinds of delta numbers.
I'm sure water wetter would help, but the difference it will make is going to be very minimal. If we want to see significantly lower core temps, we need to either improve the thermal conductance of the die itself, or go sub ambient.
Iirc, the water-wetter helps by preventing localized boiling at hot spots in the engine block. If your die never gets near the boiling point of the coolant that's probably not benefit to you.
As the other comments say, I don't it will really do anything or something significant, but, "this is LTT!" (Read as in "this is Sparta!") So yeah! They should do that video Ltt style.
Or Engine Ice
Water wetter will not make you engine run cooler, it raises the boiling point significantly so you can be safe at the high temps you see at the drag strip. IIRC it was meant to be added to engines running straight water. If you have antifreeze/coolant already it will do nothing they aren't already doing.
Seems like a very cool fluid!
But im also very interested in a long term test vs. a „normal“ coolant to see if there is more or less abrasion on the coolers and if there is more or less residue from the particles falling out of solution.
Evaporation-rate shouldn’t be significantly changed vs. normal coolant or distilled water
and Evaporation-rate is also dependent on how airtight your loop is.
When comparing keep in mind your cryofuel was used. It would have picked up ions over it's life in the loop. Fresh fluid might be less conductive. Same goes with water, after a while of running in a loop it will pick up ions from the loop components.

The bigger your radiators are, the less temp-difference you'll see... It is better to invest in a bigger radiator.
This kind of fluid is only useful if you have small radiators en high temps!
12:31 Maybe the "anti-foaming agent" is more of a film that traps bubbles on the surface and prevents more air from getting in?
When he said "you don't want bubbles forming on the microfins", well for that, where would the air come from? On the contrary you actually want surfactants (tensides) in your liquid that would break the surface tension and allow it to flow around the microfins better; but tensides are literally dish soap, so at the surface, they can tend to form air bubbles. I also think a small amount of surfactant can help remove the air better wherever it can be in the loop.
Maybe the resulting foaming can be disconcerting, so maybe they added tensides to improve performance, and added anti foaming agents to then make it... not foam over in the reservoir and not look so scary.
The graphene would have to come in contact with the walls for this to work effectively, the boundary layer of a flowing liquid should prevent most of that from happening.
So in other words the graphene does not do much except add a sort of liquid charcoal look. It IS is amazing looking though, very different from just a black fluid. If I has a water cooled PC I might even buy some, provided it does not clog the system up.
I guess the other stuff creating a coating around the graphene particles (as they guess in the conductivity part) doesn't help either. i guess all it really does is making the liquid look fancy and be wayyy more abrasive at the same time...
Yeah. Hearing how graphene conducts heat, it seems like it would be more useful as a heat pipe than something mixed in with the coolant.
@@bilateralrope8643 I thought so too, like integrate it into a new "heatsink" design
this is not correct at all, please do some research on nanofluids. the heat transfer mechanism is still up for debate but there are very concrete gains in conductivity with nanoparticle suspensions. that being said i would never put them in a pc cooler as suspension stability is the hardest part of the equation - an engineer with research experience in nanofluids.
I'd be curious to know what the specific heat capacity of the coolant is. I dont see the conductivity being a big deal, but instead how much energy it can hold and how hot it gets. I could see conductivity being a big deal on a heat pipe, but for water cooling you are just putting heat into the water at the block, then physically moving it to the radiator to offload it. If it holds more energy with less of a temperature rise it could be very interesting.
Thermal conductivity is everything in coolants. For reference watch this: th-cam.com/video/-SVYKeSKBhY/w-d-xo.html
Short term you are right, the heat capacity will be more important as it will essentially offset the temperature increase by some time. For long running and heavy processes however, basically any coolant will absorb enough heat for its temperature to rise. The point then, is to be able to absorb as much as possible while near the hot parts and to off-load it while near the radiators. Since there's a flow the time each molecule has to absorb and radiate the heat is limited which is why thermal conductivity is important.
Like the previous commenter said, the thermal conductivity is a very important factor. In addition to absorbing heat more readily, it also disposes of heat more readily. This makes your entire system more efficient. The loop they did was very small, but I imagine in a larger loop, possibly with multiple radiators, this would have an even greater performance gain.
@@BL1zZ4Rth I have been digging around trying to find some stuff out, and the science gets really complex considering specific heat capacity, conductivity, viscosity, density, and I'd need to have a proper sit down with the science to get my head around it.

Tried this stuff in my water cooled laptop build because it looks SICK. Within a week my dry break quick disconnects started to become less and less dry break. They never leaked but they went from next to no fluid coming out to needing to keep a paper towel on hand when moving the laptop because about .5ml would be coming out. Looked great but with how quickly it was gunking up the connectors I flushed it.
Coolant additives will never have much effect, the heat still has to conduct through a layer of water to get to the graphene particles. Heat capacity of the coolant also doesn't matter much if you can simply make the pump run faster. The limit is always conduction into and out of the fluid.
Actually, the limit is usually the radiator and heat transfer from liquid to metal to air.
In my system, running the pump faster does literally nothing to temps. That's because there is already PLENTY of heat transfer into the liquid, but the radiator is the limiting factor. Most water-cooling loops would be the same - unless you have an enormous amount of radiators, it's the radiator capacity that limits the system
id like to say the anti foaming agent is required because they have to use a surfactant to keep the graphene from coming out of solution. surfactants are like soap latching onto the water and the dirt/graphene so it would foam up. comparing this fluid to how much water foams up isnt a fair comparison since it doesnt have a surfactant.
I don't see how it's not a fair comparison. They compared it to both distilled water and water with coolant in it. There's really not anything else to compare it to.

The first thermal test was run on furmark which cooked their GPU pretty good. I don't personally know of anything better to peg the GPU with.
They also should've measured the temperature of the fluid at different parts of the system to see if the fluid was the bottleneck or the radiator (is the cpu/gpu not getting it hot enough or is it that the fluid entering the cpu/gpu is already pretty hot)
I didn't watch the vid, but there is a product called Water Wetter, for automobile cooling systems that actually does enhance cooling. A magazine test said 2 bottles, instead of the 1 recommend on the label, actually increased cooling.
So, I bought a couple bottles and tried it. Sure enough my coolant temp dropped about 5C. During the summer, I ran mostly purified water with a couple bottles and it worked with typical coolant or plain water. I'm not sure how compatible it would be with pc liquid cooling parts and you'd have to refigure the rate of 2 bottles to 1 gallon of water for your reservoir, but the product did actually work.

Also, like with all dyes and additives - the real test is letting the system run for a year. My guess is that you can just as well throw that system in the bin after a year, one bad thing about highly conductive additives is that they bond like superglue to metals after long exposure :/
Wonder how the liquid holds together after being in use for long while
This. If it clogs your system, is abrasive or somehow solidifies over time you're better off with the old liquid. If not, it's selling point is pretty much "it looks interesting".
@@ragetist graphene is a lubricant, it is not abrasive. It wouldn't solidify, and it wouldn't clog because the particles are so small. It is 3-4 degrees cooler, so clearly its selling point is beyond "it looks interesting".
If it's incredibly thin & unidirectional... wouldn't the more obvious cooling application be in heatsinks fins?
It would conduct to the fin edge while insulating the whole face
if you coated the inside of a heat pipe with it, that could work very well.
That might have been the most engineers-i-need-your-help thing i've ever seen.
That is the complete situation that it needs to be, but instead we're having a meeting with 12 people (of whom 8 are completely unnecessary or even remotely close to the problem)
6:03 - 6:25 This is what it could be like, this is my heaven
Id really love to see how that coolant works out in the long run, regarding building up gunk etc
I can get to 8°c by playing inside my room.
This room is a damn freezer

Man I would love to trade rooms with you, mine sits at a toasty 28-30°C for most of the day :')
The flow from around @9:58 is amazing...
I'd want to see how it turns out looking after a few months of consistent usage before buying, but if that was good I'd definitely consider using this to build some sorta like dark matter themed build
“It’s the most conductive material in existence”
Imagine your system leaking…
Not like they addressed that directly in the video.
Oh wait, THEY DID.
@@falxonPSN ok, give me a timestamp for where they talk about it leaking.
@@etfoltz it was right after they said it was electrically conductive they said "so not very good for your pc"
4:05 “she’s bleeding, it smells bad”
Totally feel you bro.
Hey I noticed right from the start of your testing, you had introduced some major flaws. You said the micro graphene bits are what rapidly take hold of the heat from the CPU and then cools more rapidly in the radiator. One problem I noticed right from the first attempt, was that you never vigorously agitated the micro graphene bits into the GoChiller coolant liquid properly. You were leaving a huge amount of the graphene sludge particles in the bottoms of the containers. The test bed system, needed to be tested with water, then drained and dismantled to allow the water to evaporate or at least blown dry with compressed air. If you don't, then any residual water left behind in the rad or hoses, would have diluted the GoChiller and possibly even made it loose some of its coating properties. You also contaminated the GoChiller product, when you added it to the 1st PC which was full of that red coolant's sludge. To be thorough you should have added only brand new bottles of properly mixed GoChiller graphene, to a clean dried out PC for it to work at its full potential. It was very entertaining to watch, so keep up the awesome content.
Although what nobody mentioned was; you should, after you filled that graphene stuff in, let the system "always running" or rather - you shouldn't let it sit to long on its own.
have you not watched test #2 where they got to test it on new test bench?
You guys really missed the point on this one. The Graphene was cooling the rooms.

I’d be curious as to what the graphene deposits look like after long term use in the microfins. The pump will remain well lubricated but I’m more curious of the deposition in the blocks. Then again it is curiosity more than anything as I am still a long way away from wanting a custom loop.
I'd be interested to see if any of the graphene settles out of solution while the PC sits for a while. With large reservoir pump combos I could see that being an issue where the graphene could build up and clog the pump.

"The coolest coolant" would have been a great title
@Ľîñùş Țęçh Ţíp what the heck? Get a life scammer.
You should do a long term (6months or so) of constant use with a heavy load put on for like 3-4 hours a day to see if the heat causes the graphine to solidify to cooling fins in a cpu/gpu water block and since its more viscous and heavier per millilitre than distilled water and see what wear/flow it does on the pump

That fucking homunculus...
If Alex grew out his hair he could look like Hohenheim
"Except leave the Laboratory" made me bark a laugh out loud.
“You know what’s also awesome? The Segway to our sponsor” He’s slowly turning into Linus…
Curious if the graphene in this liquid could also offer a potential lubricating effect on the pump or other parts of the system, judging from the lubricating properties of graphene and graphite.
I'm super curius if the distilled water or the other coolant impacts the black liquid. It almost seems to be separating. A nice clean and dry to start with test bench would be cool. Also hope the liquid used in the machines isn't the same in both tests to prevent contamination. Nice video thanks for making it!
They should've used carbon nanotubes instead of graphene, or something quantum.
Artificial intelligence, blockchain and golden ratio would probably also help.
Or just upload all the heat into the cloud and download new RAM
That looks so cool. If it isn't catastrophic I would definitely love to make a build around that :o. "My machine is cooled by darkness!"
Alex: "Keep holding it right there, I'm gonna blow."
Me: "That's what she said."
I can see that Alex is now improving in hosting videos thanks to talking what's in his mind rather than reading what's on the teleprompter and switch to a humanoid bot body language. I like it!
Big companies: * stop including chargers *
Volta: " It's free real state "
the most effective custom loop liquid is a rare formula called dihydrogen monoxide, with necessary additives of course. premixes that are just distilled water + additives are also valid.
When he says: *conductive*
I felt that!

As someone who writes calligraphy it's looks just like the ink we use. This is a great learning experience.
Try water wetter. They use it in race cars and I think it drops their coolant like 12°f
The bubbles in the foam test were from you not using a clean tool every time. It's like mixing 2 different vehicle oils because of the residue on the tool, will foam 100% of the time.
The first minute and half the only thing i could think was "He is going to drink it"
With all sorts of unknowns about the chemistry of the "moss killing" and "anti-foaming" coolants, I wouldn't be handling them without skin protection and something that will definitely keep even tiny droplets from getting in my eyes, nose, or mouth. Yeesh!
He's actually hoping to become the symbiote
Graphene might conduct heat better, but it's specific heat pales in comparison to pure water. However, you're never going to get a lower temperature than the environment. (entropy)
As a chemist, I'm chuckling at "one-atom thickness." Sheets with a weak bond are nothing new.
So how long will the pump handle the abrasion of the graphine particles?
Exactly my same thought. How long until it builds up on the tubes or components and you have to buy a new set because it looked cool for 3 months

Have to say this title confused me, thought it was a cooler promising to keep your CPU at 7°c. Which seems impossible but dropping temps by 7°c seems like a more possible claim? *watches video*
me too LOL
Place a small, spirally bent wire into the drain, facing downwards (with a parabolic curve if you have the pipe sideways) and it should do the trick, just make sure the wire is somewhat same size as the drainage pipe. The draining stream should follow it.
