It sounds too good to be true but also technically plausible. I really hope that this actually works because it makes so much sense in our modern energy economy.
This is super true, it is already used in a lot of places where installing aircondition is a problem. You can actually go further and use the heat to warm the building... so you save more energy. So, technically is possible, but you might find a little problem getting the permision to play arround with some many systems, and that was my main problem working with for the last 3 years. The owners of the buildings are usually pretty stupid.
Because it is. Water isn't conductive. The stuff IN water is conductive. And the microscopic bits of metal and other residue that this winds up with inside it will wind up conductive eventually too.
This is one of the coolest things I've seen in a while. Imagine in 15 years if this is common practice for large server setups, paired with renewable energy from solar/wind etc. Renewable energy to power the server farm and surrounding equipment, and re-using the heat generated to help power the building or provide heating.
There are plans in Germany to push waste heat from data-centers into the teleheating network. And yes, we need more of that. Why just dump the (useful) heat into the atmosphere?
The energy recovering is the most interesting part. It can still do work properly harnessed and hopefully we see more of that soon. Pretty cool they could have it integrated with this system
All water cooling have that advantage, but on servers you don't use water cooling due to risk of leakage that can damage not only the server, but the entire rack. And home PC will just produce too little heat for it to make sense to recycle it. But with this, you can "water" cool an entire server room and produce so much hot liquid for it to make sense to reuse that stuff.
its not poisonous but probably not perfectly hand safe either, would be really interesting to see how this is better than the other dielectric fluids, some of which are banned in the US or the EU or both

I wouldn't say innovative, innovative basically implies new prospects. This is a new chemical for old functions. Like they even say in the video, we already have evaporative NOVEC and mineral oil. It's just a slightly different chemical with a similar function to NOVEC.
@@demp11 it's more like saying biofuels are innovative, they're literally just a different way to make the same material. Or that ethanol based gasoline is innovative over lead based gas. It's safer no doubt, but it does the same thing in the same way. That's the definition of iterative not innovative. The first cellphone would be a mix of both for example, we already had radio transmitters and microphones, making them smaller and lower power was iterative, giving it a battery and make it portable is innovative. The majority of invensions are iterative over innovative. We already have such deep material and physics based studies, it just takes putting them together in the right configuration or using them in a way we haven't before to be iterative. Simply put, the difference between iterative and innovative is iterative is doing something better than before or improving on it , a hydrogen fuel cell car is still a car for example, and innovative is making something that is either completely new or brings new value like the invention of the touch screen or maglevs.
This is actually a really neat idea. I work in a large datacenter, and managing hot/cold containment is a huge pain in the ass. No matter what we do, our containment either leaks air somewhere or the return CFM isn't strong enough to pull the hot air out. Most of the racks we get are full of 4-node chassis that look just like the ones demonstrated here. Those produce a boatload of heat....Supermicro, Lenovo, etc. Each rack gets a pair of switches that all the nodes connect to over cat6 RJ45 cabling. Those switches have fiber optic uplinks that go upstream to the network. Those switches, or at least the fiber ports, could remain exposed so there wouldn't be any problems with the fiber. Switches don't produce that much heat anyway, so either they could remain partially exposed or fully. This would be a really neat way to do heat containment!
I’d imagine fibre connections that were designed for submersion will start to appear. Also all those 50W fans will be adding to the heat load, simply getting rid of those must cut it quite a bit
@@____________________________.x They do have DAC/F (Direct Attached Copper/Fiber), those are basically just cables with a built in SFP transceiver, but there's a massive downside to those - can't replace the SFP. If it goes bad, gotta replace the whole cable. Would be nice if they made a protective cover or something that would seal up the SFP once the fiber is connected
Im so glad to see us considering what more we can do with our “waste” energy. Its kind of absurd when you look at all the ways we pay money to generate heat then chuck it out the window, when there are easy ways like this to actually make that same heat do some work.
Yeah there are a few things finally starting to take advantage of it. Obviously data centres have been starting to harness waste heat to heat water/air but there are so many other cool technologies to better manage heat energy. My house has a ventilation system with a standard heat pump (heat pumps are fairly new in America, but extremely common in my country) built into the system and a heat exchanger so fresh air is drawn from outside, passes over a heat exchanger which transfers heat from old air being removed from the house and then either straight inside or topped up by the heat pump. Means we're not venting warm air outside or pulling cold air in, some energy is kept inside the house even as the air itself is refreshed. Not perfectly efficient, of course, but better than nothing.
@@helplmchoking air conditioning literally is a heat pump and america is known for AC. though its nice that someone realized out you could turn it around (or just run it backwards) so it can be used to heat things too, and took it to market.
A yes. Reminds me back in 2015 when I was mining crypto in my dorm in the winter and could turn off the radiators and keep the window open all day long for a nice comfy temperature. In the summer it was less fun though.
Hi! Waste of energy presents a great opportunity for monetization and innovation! We're excited to keep exploring these ideas with our partners; keep an eye on our social channels!
I so prefer seeing Anthony host when he does. The just pure knowledge and humbleness he puts off is a breath of fresh air. No ego, no attitude, just a dude that loves tech and seems very approachable and down to earth.
they are using servercenter heat for district heating here in Denmark, so it can be done if they are willing to do so. So that helps heat houses and water all year round (well no house heating during summer but it helps make hot water so people can shower and such) and during winter it helps with whole house heating, district heating is quite widespread in Denmark and powerplants spare heat is used for that.
I wonder how viable it is to use thermoelectric panels to convert the heat back to electricity, or at least recover some of it. I think they're more efficient when there's a cold side, so I feel like that would fit into water cooling pretty well compared to the backside just being warm air.
Our company hooked a small heat exchanger between our server and the underfloor heating tubes, its great during day time since server is going full blast, it actually saved us when electricity went out for some time and our emergency power only covers the server.
I agree 100%. even though i don't personally understand a lot of the things mentioned nor have a use for them I always appreciate his genuine interest, explanations and overall fascination with the topics he covers. anthony absolutely kills it every time he's on camera and the videos he hosts are almost always my favorite for being so informative.
@@ChilliCSGO Yes everything is scripted, but you must also realize someone or multiple individuals created said script. These scripts aren't just magically created by consuming a wish from a genie. Someone actually puts in the leg work. And I've noticed, when Anthony is present, the writing is way better. Probably because he WROTE the script. Love linus to death, he is an amazing host and contributes his own character to the channel. But let's be honest here, when Anthony is on screen, the show get's way more intelligent. His Persona is way different from anyone else. That isn't a coincidence. The writers aren't purposely making him smart. He does it himself. So I can almost guarantee, when he hosts, he has a hand in the script. As the entire segment/video exudes his character. You know an Anthony video top to bottom. You absolutely know what you are going to get from him. That isn't some random writer. That's him. As it's way too "routine" to explain otherwise. His videos are way too consistent to be from a writer team. As they'd carry that spirit over into other segments on LTT.
It's great to see new cooling solutions like this also being water-efficient, especially with water usage concerns becoming more common these days. Seems like an awesome solution and the ability to easily use the waste heat is such a great feature. I know that one of the big office buildings in my area uses heat from their servers in the building to help heat their big atrium in the winter.
Anthony is the best host you can imagine for these kind of show/conference coverages !! I've always been bored to see the conference coverages elsewhere but Anthony makes it all the interesting. GG LTT. Anthony is a gem
@@sermerlin1 not all HDD's are vented. For example HGST's helium drives were entirely sealed due to their helium gas component. They could completely survive immersion. You'd just have to buy the right drives.
I really hope Linus gives him more air time. The man is extremely knowledgeable and us geeks know when he shows his face, we are in for a treat! Seriously, anthony means = complex, interesting tech. We love him for it.
this seems like a very smart solution that not only fixes the main problem but also goes that extra mile and fixes other problems, and is future-proofed too, i love it omg
Can't wait for immersion cooling tech to enjoy widespread adoption in data centers. It'll simplify so much. The approach of flowing hot and cold air around contained aisles is decades old and ready for a fundamental update.
I will never get used to seeing plugged-in electronics submerged in liquid. Everything I was taught growing up about the hazards of mixing liquid with electricity makes this video not sit right with me, even if I know it's safe 😆
This is like how it's counter intuitive that Microsoft's undersea servers prototypes have a better longevity that normal servers. But because they are in a submarine-grade water and airtight hull filled with pure pressurized nitrogen, there is no oxygen nor humidity inside to corrode the hardware.
that's water, not liquid you shouldn't mix with electricity. De-ionized water is also fine BTW, it's the ions that make water conductive, it's otherwise dialectric.
@@Freshbott2 technically yes but the water outside allows for better heat transfer because it is colder than the air on surface level and way better at taking heat away
Plus submerging the data center helps reduce the strain on the hull if they choose the right depth. Having the internal pressure and the external pressure being equal is the ideal scenario and even outside the ideal scenario, the smaller difference between internal and external pressures the better.
I hope that they release the fluid to enthusiasts because I've been wanting to build a submerged pc but didn't want to deal with the oil and pc components failing from the deteriorating effects oil has on plastics
I hope so, but I kinda doubt it. This is the kind of stuff that usually only comes to datacenters as the costs are vastly more than even water cooling. I mean it literally needs a cooling tank beyond your computer.
The way the heat is more efficiently used in other areas of the building reminds me of what Iceland does with it's hot water as a by-product to the geothermal energy it produces. Iceland produces so much hot water that there are man-made hot springs where people can have a dip... I'm sure there are other uses but that's the only one I can remember. I can imagine a future where Little Timmy's PC gaming is the cause to the whole house being heated rather than relying on central heating.
Anthony appreciation post. He simultaneously is helpful to people who are experienced with the subject matters he talks about, while also not talking down to people who are newer to topics. I know this because for some of these subjects I'm new at, and I can always feel welcomed... and other topics I know a lot about, but I can always appreciate those, too, in different ways. t takes a charismatic person to be able to do this effectively with presentation. Anthony rocks.
Big agree, he never feels like a gatekeeper, he's very welcoming and has really good energy as a host Also he gets excited about crazy shit like this and it makes it more fun as a viewer
Wow, this is genius, practical, and insanely efficient. Give this technology more time to mature and we may see underwater server racks be the norm in the future.
I love how the LTT community will roast linus any chance they get and tease the other hosts lightly, but when it comes to Anthony everyone just loves the guy. I mean how can you not? Hes great!
i did it way back when. over ten years ago with mineral oil works great but like anthony said it can be messy when you have to upgrade or replace parts. this new liquid looks like something i would like to try. my old mineral oil pc cools itself with a aftermarket trans cooler a fishtank pump and two case fans mounted to a custom plexiglass backpanel behind the fishtank. great fun project and overclocking is fun i got my q6600 intel cpu to 3.4 ghz without issues. Used it for a ventrillo server and a clan webpage and forum back before youtube and facebook.
If It would reduce energy consumption in the long run I would consider the investment, but a server with an embedded celeron and an i5/3050 system being my top power chompers, it wouldnt be worth the investment.
I love this amazing idea to integrate with building heating especially with the brute force approach of all the electronics manufacturers. Exactly the sort of content I love this channel for
I thoroughly enjoyed watching this video. I honestly cannot decide if I had liked listening to Anthony speak or listening to him speak about the product. Or all of it. Awesome video, awesome new tech on the way.
I'll be honest, I wasn't sure about Anthony when I first saw him, but he really showed how great he is at literally like most things tech. Super happy that he's on LTT!
I assume the liquid is mostly dimethyl sulfoxide. It is used to protect cell cultures when frozen. Up to 10% of the water can be replaced with dimethyl sulfoxide without killing them. The ice of this mix does not expand as water ice, so the cells do not burst when frozen. But dimethyl sulfoxide that has been used as a coolant should never be drunk as it can over time dissolve water-insoluble compounds such as plasticizers and therefore become toxic. Pure dimethyl sulfoxide melts at 19°C, so an additive is used here to make it more fluid at room temperature. This additive probably also removes water that is absorbed from the atmosphere.
I really can't imagine a practical use for this in a data center except for very specific applications. I worked in a data center for a couple years and to apply it and I see a lot of challenges. But still I would love to see this implemented
Agreed. A suite of these would require so much floor reinforcement its unfeasible, for edge nodes maybe on premise, but for a DC that's not happening without big changes. Equally, I wonder how manufacturers warranties are affected by use of their hardware in submerged cooling. I can see that being a great limitation for many companies.
I can see this fluid being a major game changer for those who are interested in water cooling but are worried about potential leaks. Is this something that would be made available to the general public eventually?
what a cool innovation, url looked up and sent to my support team already! can see hundreds of applications for immersive cooling in our ECA and pharma manufacturing labs. Kudos Anthony superb presentation and you can see the passion for all things tech with you sire! keep it up mate.
In our country is one datacenter with fully submerged servers with IO too, but in "old way" - mineral oil. They use the heat from servers to heat up offices in winter and city pool which is near in summer...they have been working on that idea about 5 years before they even started building the datacenter. They even have contract with some of the big names in server world that they have warranty even if the hw is fully covered in oil... :)
I feel like in the future, after a few years or so, this will become the mainstream server cooling for major companies and probably also for commercial use.
Most important thing about that is the easy possiblity to connect it to heating. Large Server farms are a crazy emitter of heat, which could be used for heating in winter.
@@Freak480 can you give an intervie on something on that. I am genuinely interested in knowing more here because gas exchange in the lungs is completely passive and the gases just flow in and out through a stupidly thin cell layer into capillaries. I can imagine it must feel awful to have your lung filled with a pressurised fluid and akso that the musclrs you use for ventilation must really not like that. Honestly scary thought
This is the best marketing this company has gotten, I've been practicing my spanish watching their old youtube videos in spanish with 30 views. They should send you a system to play with lol.
I am curious to see how they would deal with contamination, this filter thing, as it could potentially make the liquid conduct electricity and damage everything.
@@waynesallee-com Well pure water does not deliver electricity, its the contaminations in water that do that. I somehow get the feeling this is distilled water they are using with some anti corrosive chemicals added to protect the system, these being somewhat low boiling point chemicals around 100C so it can be cleaned via distillation. Maybe you could even run distillation by running the heated water in batches to separate container that gets heated and distilled in phases to remove contaminations. Cool system and i would love to know more about what this liquid might be, but hard to say. Tried looking into Hypertech patents to see if there was any info, but could not find anything related on their name, though patent could be under someone elses name, to try and hide the information, so those that are into this dont just try reverse engineer this stuff based on patent information for personal use, or they havent done the patent application, though i doubt that. Well we will know in future and yeah home pc with this system would be pretty nice, specially on hot days, to be able to dump that heat outside. I wonder if this stuff freezes easily..
@@Hellsong89 Yes, it is true that pure water does not conduct electricity, and that it's the impurities that cause water to conduct electricity, but keep in mind that any bare metal coming in contact with the water will add metal ions to the water, and gasses dissolved in the water affects it's conductivity. Trying to keep water non-conductive would be more trouble than it's worth. And while it's possible that they may have done as you have said, that would not work long term, because the water would soak into areas that have very slow to almost no flow. As the water slowly dissolves metal and other impurities, the conductivity in those spots would slowly increase uncontrollably. Water could make for a great illusion at a trade show, but it would not work long term. Also, if you read the spec sheet, that stuff is flammable.
At first I was like, "Oh it's just a better mineral bath." But the fact you can just dump the heat into water easily is SUPER cool. That's a great use for the waste heat.
Thats useful, but I wonder if its cost effective, we'd need to know hot water temperatures and mass flow rates to decide whether or not there's a lot of exergy there
This sounds quite amazing. Next to removing the need for a strong HVAC it also solves the problem of fire for many Datacenters - if I understand correctly. If all systems are sumberged in a non-flamable liquid you should be able to skip a costly Halon- or Oxygen-reduction system in your DC.
I love this! I've always loved the idea of a submersed computer, but oil has too many downsides. This seems way better. Hopefully you guys can do a new aquarium build with this.
@@The_Keeper I mean there was a gap between the two where it was somewhat better, with intakes on the side panels for direct GPU cooling even being a common and in style thing. Then came tempered glass...
This product suffers the same problem for why mineral oil never become a big hit. If there needs to be any maintenance it becomes a big liquid mess. Its really awesome and I support liquid becoming normalized. But until its a clean self enclosed unit as part of the package. Its just not practical for most applications. Despite the energy savings. I also dont see any company tying this into any of this drinking water as mentioned in the video. All kind of regulations that idea would break...
If you ask me something like this is clearly the future. Not only does it save energy, it also allows for much much higher power densities (which will give you increased performance) and server farms can be smaller.
Yup, even small % savings in energy costs and hardware longevity results in millions (if not more) in cost reduction. When you're working on the scale of data centers like Google it's a no brainer assuming it does what they say. If the tech works and isn't a giant hassle to install into data centers and maintain that is.
Yes normally this type of system is used in large GPU and ASICs crypto farms if you research a little you will find a lot of people using this type of tanks
My university degree final thesis is to create a hw simulation of GPU load to submerse in another coolent and analyze the quantity of heat it's able to disipate. This video is a very good summary of all but in a more advanced stage. I very much like your story telling of the picture :)
We'll see this deployed at LMG when? No doubt Linus will want to play with this! *note* - I commented before the end of the vid. Anthony mentioned deploying it at LMG seconds after I had hit the summit button 🤣
Weird, I just finished season 3 of the Prime series Hanna last night and one of the episodes featured a farm of tank-based servers like these and I figured it was just pure imagination on the part of some production designer
I've dealt with Mineral oil data centers (and the company I work for partners with Hypertec) for 10 years now, this is a welcome upgrade for those centers.
Super cool, literally. I am seriously doubting the environmental/safety claims until they release what's in it, preferably getting a proper MSDS. Even if it didn't meet those claims, it's still definitely worth for industrial applications.
Even if the solutions aren't so enviormentally friendly, the efficency and potential waste heat recycling could be enough for a breakthrough, hopefully.
If you added Peltier heat pumps to the heat exchangers then numerous server racks could all export heat to the same master loop which could run extremely hot and run a steam turbine. Some server farms use insane amounts of electricity, far more than would be needed, recouping this for the office or local facilities or back to the grid would be an outstanding solution!
I work in cnc machine and we used some thing almost identical to this its called EDM fluids. This fluid is able to handle heats up to and hotter than the surface of the sun..in atomic level of course but add a standard 1/2 water chiller for vacuum mold coolers and you can run this stuff at sub temps cause it doesnt frezze.
This is great. Could potentially be very powerful alongside some kind of "server source" heat pump, making heat pumps an option in large buildings where they otherwise wouldn't be

Means we're not venting warm air outside or pulling cold air in, some energy is kept inside the house even as the air itself is refreshed. Not perfectly efficient, of course, but better than nothing.
@@helplmchoking nice! Yeah those type of heat pumps are great, and pay themselves off pretty easy.
@@helplmchoking air conditioning literally is a heat pump and america is known for AC. though its nice that someone realized out you could turn it around (or just run it backwards) so it can be used to heat things too, and took it to market.
A yes. Reminds me back in 2015 when I was mining crypto in my dorm in the winter and could turn off the radiators and keep the window open all day long for a nice comfy temperature.
In the summer it was less fun though.
Hi! Waste of energy presents a great opportunity for monetization and innovation!
We're excited to keep exploring these ideas with our partners; keep an eye on our social channels!
I so prefer seeing Anthony host when he does. The just pure knowledge and humbleness he puts off is a breath of fresh air. No ego, no attitude, just a dude that loves tech and seems very approachable and down to earth.
I love when he gets pissed and cusses out hardware makers 😂😂
I have been a firm advocate of utilizing "waste" heat in so, so many applications, compute heat specifically.
they are using servercenter heat for district heating here in Denmark, so it can be done if they are willing to do so. So that helps heat houses and water all year round (well no house heating during summer but it helps make hot water so people can shower and such) and during winter it helps with whole house heating, district heating is quite widespread in Denmark and powerplants spare heat is used for that.
I wonder how viable it is to use thermoelectric panels to convert the heat back to electricity, or at least recover some of it. I think they're more efficient when there's a cold side, so I feel like that would fit into water cooling pretty well compared to the backside just being warm air.
Our company hooked a small heat exchanger between our server and the underfloor heating tubes, its great during day time since server is going full blast, it actually saved us when electricity went out for some time and our emergency power only covers the server.
@@5PYZ3R those panels are highly inefficient
Can the heat be used to pump the liquid?
Anthony is amazing. Seeing his confidence in this video is so natural.
Loved this video. Great job Anthony!
I agree 100%. even though i don't personally understand a lot of the things mentioned nor have a use for them I always appreciate his genuine interest, explanations and overall fascination with the topics he covers. anthony absolutely kills it every time he's on camera and the videos he hosts are almost always my favorite for being so informative.
Anthony's such a legend! His knowledge in everything he shows and does is extremely impressive. Always enjoy vidoes he's in!
No doubt the guy is a technical mastermind but remember its all scripted and read from a screen.. Like news presenters.
@@ChilliCSGO Yes everything is scripted, but you must also realize someone or multiple individuals created said script. These scripts aren't just magically created by consuming a wish from a genie. Someone actually puts in the leg work. And I've noticed, when Anthony is present, the writing is way better. Probably because he WROTE the script. Love linus to death, he is an amazing host and contributes his own character to the channel. But let's be honest here, when Anthony is on screen, the show get's way more intelligent. His Persona is way different from anyone else. That isn't a coincidence. The writers aren't purposely making him smart. He does it himself. So I can almost guarantee, when he hosts, he has a hand in the script. As the entire segment/video exudes his character. You know an Anthony video top to bottom. You absolutely know what you are going to get from him. That isn't some random writer. That's him. As it's way too "routine" to explain otherwise. His videos are way too consistent to be from a writer team. As they'd carry that spirit over into other segments on LTT.
It's great to see new cooling solutions like this also being water-efficient, especially with water usage concerns becoming more common these days. Seems like an awesome solution and the ability to easily use the waste heat is such a great feature. I know that one of the big office buildings in my area uses heat from their servers in the building to help heat their big atrium in the winter.
Anthony is the best host you can imagine for these kind of show/conference coverages !! I've always been bored to see the conference coverages elsewhere but Anthony makes it all the interesting. GG LTT. Anthony is a gem
I wish they made a small version for home servers, this looks absolutely sick...
Yeah! I'd love to be able to shove 2 PCs and a small personal server in there for home use without breaking a bank. That would be awesome!
And for home gaming PCs please.
wouldn't work on a NAS =(
@@Scotschie it will if it's SSD storage. But Yeah not with HDD.
@@sermerlin1 not all HDD's are vented. For example HGST's helium drives were entirely sealed due to their helium gas component. They could completely survive immersion. You'd just have to buy the right drives.
I thought there’s no video today. Good to see Anthony is having fun!
Anthony has become such a great host. I am so happy Linus gave the push he needed. Just look how awesome the videos are now
I really hope Linus gives him more air time. The man is extremely knowledgeable and us geeks know when he shows his face, we are in for a treat! Seriously, anthony means = complex, interesting tech. We love him for it.
I was thinking thinking the same thing. He used to be super awkward to watch. Now i love watching him. Need Moar Anthony Plz
this seems like a very smart solution that not only fixes the main problem but also goes that extra mile and fixes other problems, and is future-proofed too, i love it omg
Can't wait for immersion cooling tech to enjoy widespread adoption in data centers. It'll simplify so much. The approach of flowing hot and cold air around contained aisles is decades old and ready for a fundamental update.
The perfect excuse for linus to build another " FIVE PETEBYTE server" and I'm stoked to watch every second of that 22 minute video haha
@@nemesis2264 I think you right
I will never get used to seeing plugged-in electronics submerged in liquid. Everything I was taught growing up about the hazards of mixing liquid with electricity makes this video not sit right with me, even if I know it's safe 😆
This is like how it's counter intuitive that Microsoft's undersea servers prototypes have a better longevity that normal servers. But because they are in a submarine-grade water and airtight hull filled with pure pressurized nitrogen, there is no oxygen nor humidity inside to corrode the hardware.
that's water, not liquid you shouldn't mix with electricity. De-ionized water is also fine BTW, it's the ions that make water conductive, it's otherwise dialectric.
@@18earendil can’t they just do the pressurised nitrogen hull and keep it at the surface?
@@Freshbott2 technically yes but the water outside allows for better heat transfer because it is colder than the air on surface level and way better at taking heat away
Plus submerging the data center helps reduce the strain on the hull if they choose the right depth. Having the internal pressure and the external pressure being equal is the ideal scenario and even outside the ideal scenario, the smaller difference between internal and external pressures the better.
I hope that they release the fluid to enthusiasts because I've been wanting to build a submerged pc but didn't want to deal with the oil and pc components failing from the deteriorating effects oil has on plastics
sooooooooon
Did some digging on the company's website and it looks like they're using Lubrizol's CompuZol IM2015 fluid.
@@x3of9 could be a part of this new mixture yeah
I hope so, but I kinda doubt it. This is the kind of stuff that usually only comes to datacenters as the costs are vastly more than even water cooling. I mean it literally needs a cooling tank beyond your computer.
@@Skylancer727 custom heat exchanger interop with the hvac fan system, perfect for the 2x0.5 foot closet where the water heater lives
I love having Anthony get screen time, he’s very knowledgeable but he can talk in a way that less informed people like myself can understand.
The way the heat is more efficiently used in other areas of the building reminds me of what Iceland does with it's hot water as a by-product to the geothermal energy it produces. Iceland produces so much hot water that there are man-made hot springs where people can have a dip... I'm sure there are other uses but that's the only one I can remember.
I can imagine a future where Little Timmy's PC gaming is the cause to the whole house being heated rather than relying on central heating.
I love these segments. Anthony’s passion comes through in these and the information is great.
Anthony appreciation post. He simultaneously is helpful to people who are experienced with the subject matters he talks about, while also not talking down to people who are newer to topics. I know this because for some of these subjects I'm new at, and I can always feel welcomed... and other topics I know a lot about, but I can always appreciate those, too, in different ways. t takes a charismatic person to be able to do this effectively with presentation. Anthony rocks.
Big agree, he never feels like a gatekeeper, he's very welcoming and has really good energy as a host
Also he gets excited about crazy shit like this and it makes it more fun as a viewer
It's a joy to watch these videos with anthony, he's the ideal 'on the ground reporter' for this kind of stuff.
Anthony is such a good addition to the channel, and he's getting better at presenting as well. 10/10
Wow, this is genius, practical, and insanely efficient. Give this technology more time to mature and we may see underwater server racks be the norm in the future.
I love how the LTT community will roast linus any chance they get and tease the other hosts lightly, but when it comes to Anthony everyone just loves the guy. I mean how can you not? Hes great!
I'd love to do something like this with a home PC.
im gonna
i did it way back when. over ten years ago with mineral oil works great but like anthony said it can be messy when you have to upgrade or replace parts. this new liquid looks like something i would like to try. my old mineral oil pc cools itself with a aftermarket trans cooler a fishtank pump and two case fans mounted to a custom plexiglass backpanel behind the fishtank. great fun project and overclocking is fun i got my q6600 intel cpu to 3.4 ghz without issues. Used it for a ventrillo server and a clan webpage and forum back before youtube and facebook.
Well prepare for the maintenance cost lmao
If It would reduce energy consumption in the long run I would consider the investment, but a server with an embedded celeron and an i5/3050 system being my top power chompers, it wouldnt be worth the investment.
Something like this is only practical for large-scale computers rather than something that sits on your desk.
This should be fun Anthony videos are always entertaining
mans is like an amazon review where they dont even get the product yet but they leave a review 💀

@@slyticular4710 very funny very cool everyone is very fond of u
I love this amazing idea to integrate with building heating especially with the brute force approach of all the electronics manufacturers. Exactly the sort of content I love this channel for
I thoroughly enjoyed watching this video. I honestly cannot decide if I had liked listening to Anthony speak or listening to him speak about the product. Or all of it. Awesome video, awesome new tech on the way.
This is so cool to see, I hope to see it more
The environmentally friendly approach is also a really great plus!
Unless they disclose what the compound is, “environmentally friendly” is a broad unsubstantiated claim
@@chrisrobbins6783 At some point they’ll have to, if for no other reason than OSHA and safety data sheets.
I love this style of video and it’s truly interesting to the fullest extent
I'll be honest, I wasn't sure about Anthony when I first saw him, but he really showed how great he is at literally like most things tech. Super happy that he's on LTT!
I assume the liquid is mostly dimethyl sulfoxide. It is used to protect cell cultures when frozen. Up to 10% of the water can be replaced with dimethyl sulfoxide without killing them. The ice of this mix does not expand as water ice, so the cells do not burst when frozen. But dimethyl sulfoxide that has been used as a coolant should never be drunk as it can over time dissolve water-insoluble compounds such as plasticizers and therefore become toxic.
Pure dimethyl sulfoxide melts at 19°C, so an additive is used here to make it more fluid at room temperature. This additive probably also removes water that is absorbed from the atmosphere.
I really can't imagine a practical use for this in a data center except for very specific applications. I worked in a data center for a couple years and to apply it and I see a lot of challenges. But still I would love to see this implemented
Agreed. A suite of these would require so much floor reinforcement its unfeasible, for edge nodes maybe on premise, but for a DC that's not happening without big changes.
Equally, I wonder how manufacturers warranties are affected by use of their hardware in submerged cooling. I can see that being a great limitation for many companies.
I can see this fluid being a major game changer for those who are interested in water cooling but are worried about potential leaks. Is this something that would be made available to the general public eventually?
Anthony's growth as a host is really wholesome. I'm so glad to see him more often!!
I really hope energy recovery from waste heat will become more of a standard, at least in data centers.
what a cool innovation, url looked up and sent to my support team already! can see hundreds of applications for immersive cooling in our ECA and pharma manufacturing labs. Kudos Anthony superb presentation and you can see the passion for all things tech with you sire! keep it up mate.
In our country is one datacenter with fully submerged servers with IO too, but in "old way" - mineral oil. They use the heat from servers to heat up offices in winter and city pool which is near in summer...they have been working on that idea about 5 years before they even started building the datacenter. They even have contract with some of the big names in server world that they have warranty even if the hw is fully covered in oil... :)
This is actually super cool hopefully it becomes common practice
I feel like in the future, after a few years or so, this will become the mainstream server cooling for major companies and probably also for commercial use.
Depends if they can make enough of the fluid or not.
Most important thing about that is the easy possiblity to connect it to heating. Large Server farms are a crazy emitter of heat, which could be used for heating in winter.
I have missed content like this over the last three years. This is the coolest thing I’ve ever seen!
I really like seeing Anthony host, im never a massive fan when other hosts get on(with any channel not just LTT) but Anthony smashes it. Well done 👏
4 a.m., the best time for enjoying LTT
Yes it is 😄
I don't know why this reminds me of the movie "abyss" where they essentially flood diver lungs with oxygen rich fluid
Thats a real thing btw. Breathable liquids have been around for a while and do work but they take s lot more effort to breath.
@@Freak480 apparently it also feels like drawing as you go between mediums. Very not pleasant.
@@Freak480 can you give an intervie on something on that. I am genuinely interested in knowing more here because gas exchange in the lungs is completely passive and the gases just flow in and out through a stupidly thin cell layer into capillaries. I can imagine it must feel awful to have your lung filled with a pressurised fluid and akso that the musclrs you use for ventilation must really not like that. Honestly scary thought
Fun fact, the part where they did the test with the rat was the actual liquid, the rat was breathing liquid on camera
This is the best marketing this company has gotten, I've been practicing my spanish watching their old youtube videos in spanish with 30 views. They should send you a system to play with lol.
2:45 Patrick basically moved the fans somewhere else. Lol
This is an exciting development, and I appreciate the environmenal friendly focus here.
I figured this video had to be special given that the upload was super-late. And hey, we’re one step closer to Atlantis being more feasible.
Anthony is a friend everybody wishes they had
Imagine a big server farm that heats up all the buildings around it. All that data center energy being useful. What a great invention.
I friggin love the Anthony videos. Dude is as interested in the tech he is reviewing as I am.
I am curious to see how they would deal with contamination, this filter thing, as it could potentially make the liquid conduct electricity and damage everything.
Yes, like the fluid might tend to absorb water out of the air.
@@waynesallee-com Well pure water does not deliver electricity, its the contaminations in water that do that. I somehow get the feeling this is distilled water they are using with some anti corrosive chemicals added to protect the system, these being somewhat low boiling point chemicals around 100C so it can be cleaned via distillation. Maybe you could even run distillation by running the heated water in batches to separate container that gets heated and distilled in phases to remove contaminations.
Cool system and i would love to know more about what this liquid might be, but hard to say. Tried looking into Hypertech patents to see if there was any info, but could not find anything related on their name, though patent could be under someone elses name, to try and hide the information, so those that are into this dont just try reverse engineer this stuff based on patent information for personal use, or they havent done the patent application, though i doubt that. Well we will know in future and yeah home pc with this system would be pretty nice, specially on hot days, to be able to dump that heat outside. I wonder if this stuff freezes easily..
@@Hellsong89 Yes, it is true that pure water does not conduct electricity, and that it's the impurities that cause water to conduct electricity, but keep in mind that any bare metal coming in contact with the water will add metal ions to the water, and gasses dissolved in the water affects it's conductivity. Trying to keep water non-conductive would be more trouble than it's worth. And while it's possible that they may have done as you have said, that would not work long term, because the water would soak into areas that have very slow to almost no flow. As the water slowly dissolves metal and other impurities, the conductivity in those spots would slowly increase uncontrollably. Water could make for a great illusion at a trade show, but it would not work long term. Also, if you read the spec sheet, that stuff is flammable.
It's just so fascinating to me that ports and electronics are perfectly fine underwater.
its not water
At first I was like, "Oh it's just a better mineral bath." But the fact you can just dump the heat into water easily is SUPER cool. That's a great use for the waste heat.
Thats useful, but I wonder if its cost effective, we'd need to know hot water temperatures and mass flow rates to decide whether or not there's a lot of exergy there
Can't wait to get me new HEDT aquarium when I need a new build!
This sounds quite amazing. Next to removing the need for a strong HVAC it also solves the problem of fire for many Datacenters - if I understand correctly. If all systems are sumberged in a non-flamable liquid you should be able to skip a costly Halon- or Oxygen-reduction system in your DC.
This would certainly eliminate my anxiety about my AIO that should go out at any time now that it is two years old.
I'd love to drop a stack of mac minis into a rack of this stuff. I bet a clever "intake" at the bottom could give it some nice laminar flow too
im a simpler person,
i see a LTT vid,
i click LTT vid
I love this! I've always loved the idea of a submersed computer, but oil has too many downsides. This seems way better. Hopefully you guys can do a new aquarium build with this.
I love seeing Anthony in his element! He's loving this even though he was possibly poisoned by the "safe" cooling liquid.....
I love that this video was 100% Anthony
Just imagine being in a stat center with like 100s of these stacked on top of each other. That's dope
The synergy loop of this great.
It'll be great to see the liquid available to use in custom liquid cooling loops as well.
Man, i remember when Aquarium cooling was a big thing, back when most cases were trash on airflow
" back when most cases were trash on airflow"
Yup. These days its "only" 50/50 whether or not the case sucks for airflow.
@@The_Keeper I mean there was a gap between the two where it was somewhat better, with intakes on the side panels for direct GPU cooling even being a common and in style thing. Then came tempered glass...
This product suffers the same problem for why mineral oil never become a big hit. If there needs to be any maintenance it becomes a big liquid mess. Its really awesome and I support liquid becoming normalized. But until its a clean self enclosed unit as part of the package. Its just not practical for most applications. Despite the energy savings.
I also dont see any company tying this into any of this drinking water as mentioned in the video. All kind of regulations that idea would break...
Ben Franklin once said, “nothing is certain but death, taxes and how people always feel the need to oddly mention how they love Anthony’s hosting”
I dont know why but I really like these videos, thx Anthony for hosting.
If you ask me something like this is clearly the future. Not only does it save energy, it also allows for much much higher power densities (which will give you increased performance) and server farms can be smaller.
This coolant would be a great option for traditional water cooling so your pc doesn't explode from leaky tubes
It's probably gonna be way too expensive for home PCs, but for server farms this could be the future
Yup, even small % savings in energy costs and hardware longevity results in millions (if not more) in cost reduction. When you're working on the scale of data centers like Google it's a no brainer assuming it does what they say. If the tech works and isn't a giant hassle to install into data centers and maintain that is.
Yes normally this type of system is used in large GPU and ASICs crypto farms if you research a little you will find a lot of people using this type of tanks
I wonder if there's longevity issues for components like mineral oil with the liquid they're using.
any video that anthony is in is like a khan academy video but fun. this guy made me get into building pcs and now installing Linux distros.
My university degree final thesis is to create a hw simulation of GPU load to submerse in another coolent and analyze the quantity of heat it's able to disipate. This video is a very good summary of all but in a more advanced stage. I very much like your story telling of the picture :)
We'll see this deployed at LMG when? No doubt Linus will want to play with this!
*note* - I commented before the end of the vid. Anthony mentioned deploying it at LMG seconds after I had hit the summit button 🤣
Weird, I just finished season 3 of the Prime series Hanna last night and one of the episodes featured a farm of tank-based servers like these and I figured it was just pure imagination on the part of some production designer
Talk about water cooling, this seems pretty interesting
I've dealt with Mineral oil data centers (and the company I work for partners with Hypertec) for 10 years now, this is a welcome upgrade for those centers.
Outstanding video.
Tell me what the animation on the left of the screen looks like at 0:10. It's not _hard_ to figure out
I'm so immature, I giggled like a schoolgirl 😂
Super cool, literally. I am seriously doubting the environmental/safety claims until they release what's in it, preferably getting a proper MSDS. Even if it didn't meet those claims, it's still definitely worth for industrial applications.
Even if the solutions aren't so enviormentally friendly, the efficency and potential waste heat recycling could be enough for a breakthrough, hopefully.
have a nice day if you read this
Hahahhaha😂
If you added Peltier heat pumps to the heat exchangers then numerous server racks could all export heat to the same master loop which could run extremely hot and run a steam turbine. Some server farms use insane amounts of electricity, far more than would be needed, recouping this for the office or local facilities or back to the grid would be an outstanding solution!
Data centers used to have this years ago. IBM had some mainframes with water chilling. I have seen water connections on many data centers in B.C.
I'm almost looking forward to having to get dive certified to go into a future server farm.
That would make datacenters even cooler than they already are! Both in appeal and temperature.
@2:10 No Anthony, my guess is NOT as good as yours.

I work in cnc machine and we used some thing almost identical to this its called EDM fluids.
This fluid is able to handle heats up to and hotter than the surface of the sun..in atomic level of course but add a standard 1/2 water chiller for vacuum mold coolers and you can run this stuff at sub temps cause it doesnt frezze.
This is great. Could potentially be very powerful alongside some kind of "server source" heat pump, making heat pumps an option in large buildings where they otherwise wouldn't be
I love Anthony's delivery. He's just got a "friend next desk over" feel to him.
