Thank you! I couldn't have asked for a better response to my question on the previous video.

[@GregSalazar]

Thanks for watching!

[@CoalitionGaming]

The expandable fractal Celsius AIO kits are similar copper/aluminum kits, and they also include a separate additive to slow galvanic corrosion. Interesting solution, good video!

[@cl4ster17]

Coalition Gaming The previous Fractal AiO series was manufactured by Alphacool and had a copper radiator.

[@CoalitionGaming]

[@CoalitionGaming]

bouke Kalkwijk Yes that's what I said, thanks.

[@MrGarkin]

TLDW: they use anti-corrosion coolant. That's all. 12 minute video with 20 bytes of information.

[@lefthandright01]

So, what we have discovered here is: 1) A.I.O's have a planned obsolescence. Either the pump will give out, water will evaporate, or it will slowly corrode to death. 2) Open loops will last longer..but only with constant maintenance and upgrading of blocks as you change hardware and regular system cleans. 3) Focusing on good air flow and investing in a reputable air cooler (And being reasonable with your overclocks) is priceless and infinitely more convenient. Gotcha. Good talk.

[@4G12]

The automotive world has been using many different metals in their liquid cooling loops for over a century. Nowadays, if you use a good OAT or HOAT coolant and change it often enough, the corrosion would be relatively minimal. The recommended change interval can be as long as 50,000km or 5 years, whichever comes first.

[@mattsmechanicalssi5833]

When Chroming steel, the process is to plate copper, then nickel, then chromium. Stainless steel also has a high nickel content to keep it from corroding.

[@jasongooden917]

Put water in an AIO, it becomes the AIO. Put water in a Loop, it becomes the Loop. Water can flow, or it can crash your system... Be water my friend.

[@VigneshBalasubramaniam]

An all aluminium kit is perfectly fine though. I feel like that should be mentioned more. Car cooling systems are often aluminium. This is also why EK has all aluminium kits. In general, for custom loops, one should avoid mixing metals. Either get all copper or all aluminium.

[@feelingtardy]

thank you. god, this obsession with copper loops. the difference is literally a couple degrees c, if that.

[@michaellesak6912]

cars have been on mostly aluminum cooling systems for decades, the cost and weight benefits far outweigh the performance gains of copper/copper alloys. but most people going with custom loops are looking for every last performance gain they can get, and weight really doesnt matter for a pc. but for budget orientated kits, aluminum should be a no brainer.

[@mjc0961]

The way people shit on aluminium, you'd think it was 30 degrees worse or something. But no. It's damn near identical. Haters gonna hate, I guess.

[@HappyBeezerStudios]

The copper used in cooling stuff isn't pure copper anyway. And the used alloyes are actually not that far above aluminum. Both are fine to use, just mixing isn't the greatest idea.

[@TrueMegaManiac]

Cars also mix metals in damn near every instance as well.

[@Likely_Alucard]

Great informative video. I am going to try out water cooling for the first time with my current build I am working on. This is a big help. I will keep this info in mind.

[@AutodidactEngineer]

I know this is old but for people that want to use aluminium radiators with copper blocks you can, just you have to use a 33% regular antifreeze to 66% distilled water!

[@flandrble]

Been using engine coolants for 20 years, galvanic corrosion isn't anything to be a concern. From the outset, it's been designed for mixed metals and plastics so zero issues.

[@MrMoxes]

A great topic for SCY. I learned this while working as a mechanic. "All metals with eventually break down to their original state", they want to return to their old states, before they were the materials we use now.

[@Vladek16]

Good video. But I hopped you'll also precise one thing : even with an all copper loop you need to have an anticorrosive (and a growth inhibitor) in it. Distilled water will erode the metal just by friction, by touching it so can still have build up of copper particules in a full copper loop that's why you need to use an anticorosive. I see too much people recommanding to use distilled water without anything in it for custom watercooling and it's a very big mistakes that a lot of people still make. That's why I hopped to see you make a video about this :/

Tech Ownage also the answer is in the first like 2 minutes when he mentions car radiators. Why everyone isnt using high performance automotive coolant is beyond me. If it runs through aluminum heads into a iron block into a copper or aluminum radiator and you get to make tire smoke with it for like 100000 miles, I feel like it will survive 60c temps for....ever.

[@mjc0961]

1. Additives. 2. You don't usually take apart/service an AIO to notice any corrosion. 3. The manufacturer is hoping for the pump to die or the liquid to permeate so you need to buy a new one anyway.

[@mjc0961]

Yeah so I was basically right, I feel kind of silly for overlooking leaks though.

[@probablynotabigtoe9407]

Wonder why they don’t use Aluminum Bronze 90%copper 10%aluminum... Very low reactivity with water. Gold color that doesn’t tarnish. high heat transfer rate. Very hard/scratch resistant. Much better material compared to pure aluminum or pure copper. I bet it’s a major cost issue, but should be the one of the best materials for the job. I think it is marketable though, AIO’s are a top end system component. So a high$ top end AIO should have a place in the market, many people would pay top dollar for something that is 2X better than the competition. FYI it is used in Marine boat Propellors because of its corrosion resistance. If I’m missing something plz explain in a reply.

[@MalcolmBlk]

My guess would be that the actual temperature differences aren't large enough to justify the price increase. Even when you compare copper and aluminum, although thermal conductivity of copper is 2x that of aluminum, the temperature difference is like 2-5 degrees. The only reason they can still sell copper kits instead of aluminum is that the price difference isn't too large.

[@fuxseb]

What about using different metals while taking care to not make any electrical connection between the two? When there's no path for electrons to flow, then ions don't flow and no electrochemical reaction occurs. Galvanic corrosion is much like a short circuit on a battery cell. My reasoning is that without the short circuit (i.e. insulate either the rad, block or both) there's nothing to push the metal ions into water. What do you think?

[@bueb8674]

With the only contact being the water itself, it will still happen, just slowly, but increasingly as the water becomes more conductive. Physically distancing(longer tubes) them will help slow it.

[@lloydcadiz5797]

While watching this, it felt like I am having my chemistry class.

[@vevenaneathna]

this is why on hondas you should only use honda coolant coz of the AL block and AL rad and if youre too cheap to use hondas 10x price coolant, I say just dont change it or use a new drip pan and decant it back in after draining. also why using that blue devil copper based gasket repair stuff, even if you follow the directions, it will cause a bunch of issues a few weeks-months later likely with the heater core getting clogged and ur heater not working after you finally decide to spend the money to fix the head gasket lol i wonder whats in the honda rad fluid, maybe some EDTA/chelation and/or alumn salt or a sacraficial zinc? might be useful for computers if u have like a data center and the brand name coolant is crazy expensive in "bulk"

[@danman1012]

Cut open a asetek gen 6 pump/rad combo. IE: h150i pro rgb, there is a clear coating in the radiator runs. It's not just chemicals anymore.

[@GregSalazar]

Most AIOs still run pure aluminum rads and copper/nickel-plated blocks.

[@danman1012]

Science Studio oh I'm not saying you were wrong, just the newest OEM Corsair AIO's do it differently than any other OEM asetek does currently. Probably because Corsair is actually solid on replacing components damaged by their AIO's if they leak/fail so they probably spend more than other OEM's

[@amessman]

This is gonna help with an upcoming project where I have to mix an aluminum rad with a copper block

[@mothafus]

I have an Enermax LIQMAX II 120S and it had massive corrosion clogging up all the copper fins in the block. That in turn made most of the liquid evaporate and the system would not run after 2 years.

[@blueckaym]

What about using full-aluminium loop parts? Like the ones in EK's FluidGaming series? And besides ThermalTake's alu-radiators, do you know of other reliable brands that make aluminium liquid loop parts (for full-aluminium loops)?

[@greybuckleton]

You will see in the thermaltake marketing material that their aluminum radiators are zinc coated on the inside. So the interacting metals are normally zinc-nickel. Both of these materials are used routinely as corrosion protection, galvanized nails ect. Any type B automotive coolent mixed with distilled battery water should prevent corosion. Green for 5 years Red for 10 years. Cars have used and still use mixed metal cooling loops without any issue.

[@xdassinx]

Change the fluid at recommended intervals. I have little doubt people never change their fluid for 5 years and were shocked at the damage. I'm still running a Thermaltake Big Water loop that I got in January 09. No problems. I completely flush the system nearly on time with their fluid.

[@elliotm01]

I bought an Enermax Liqtech 360 TR4 in Jan 2018(S/N 17...). Went bad Aug 2018. Received by RMA S/N 18... Went bad Feb 2019. It's 2 year warranty, so now Enermax is sending me Liqtech 360 TR4 II (ooh, RGB). Probably still has aluminum rad. I'm grateful I'm getting replacements, but it's a great inconvenience when it occurs. My 1950X Threadripper is often at 600MHz, at this time. Researching all this shenanigans has me more confident in pursuing custom loop in the future, on the upside.

[@animered1986]

Greg is right about the AIO's cycling particles over a long time, I have a Corsair H100 with an expired warranty. I noticed my CPU temps climbing, so I figured I had nothing to lose by opening it up. Sure enough this black and green crud/gunk was all over the cooling plate. I scrubbed it clean with a hard bristled toothbrush and flushed out the radiator with vinegar and water 50/50 mix. I cleaned the pump as best I could. it looked in good shape overall. I then flush everything with distilled water a few times. Also, I did keep the old coolant and filtered it thru a few coffee filters. I added more anti-corrosive and anti-bio to the coolant and filled the system back to full. It's been running now for over 18 months now and is keeping my overclocked aging fx-8350 under 55c under heavy load. I so need to upgrade my system :-p. with prices showing signs of dropping ill keep an eye out for good sales after summer. Oh for those that want to know how I refilled it. I just bought a large syringe minus the needle, one the fit the small hole inside the cooling plate housing and filled it holding the pump up in the air. just be very careful not to spill coolant onto the electronic part of the pump. I wrapped mine with few paper towels while filling it just in case of spillage :-)

[@Enju23]

Does this mean I can change my CPU block and GPU block and keep my aluminum rads, and get TT's C1000 clear fluid until I can afford the proper copper or nickel plated rads? 🤔

[@JimboJamboYT]

Everything in tech revolves around this one phrase.... "planned obsolescence" . Make your products work just long enough to create incentive for people to buy the next iteration of their design. If everything was created with indefinite life cycle in mind then their profits wouldnt be nearly as much as they are.

[@Austin1990]

That is not necessarily true. The longer something lasts, the more it will cost to make. Take product A that will last 5 years and cost $100. Then, consider product B that will last 10 years and cost $500. You are paying 5x the cost for 2x the life. Simply replacing product A after 5 years will cost less. It is about considering the cost over the life of the product.

[@parsastrife6629]

Just get a high-end air cooler and it will last 15+ years before the fan dies and then you can just replace that

[@chrisrawr6177]

Indeed and when you air cooler fails nothing on your PC is at risk (even without a fan on a heatsink most will not reach shutdown temps and even if they did modern cpus have thermal limits) and will cost you $15 or less you replace a fan.

[@Austin1990]

@@parsastrife6629 That is related to diminishing returns. You pay much more money for a technology that can dissipate more heat than air cooling alone can provide. But, PC hardware usually does not need the extra cooling, especially not enough to justify the additional cost and risk.

[@monkeyplayer1]

You should try and get a sponsor to help you do this since it’ll be a little expensive but you should set up 3 custom loops exactly the same with a mix of aluminium and copper and try three different coolants. One distilled water(make sure it’s a high quality one) one with something like propylene glycol or ethylene glycol. (Not sure which one destroys the tubes maybe both) maybe something else. And the last one the best pc specific coolant or additive you can find. I hope this makes sense what I’m trying to say without typing a whole page...

[@emmanuelnoel7668]

Thanx dude ,that question of mixing aluminum and copper was driving me crazy ,i will take your advise

[@illitero]

I'm at a loss as to how different metals interacting in a cooling system are any sort of mystery. The automotive industry has worked out various coolant formulas over the last two decades that are non-corrosive, non-conductive, and considered "lifetime" coolants because of the change intervals. I mean, I'm not saying to dump DexCool into your water setup (car-guy joke 'cause DexCool suxxxxx) - but I am saying that it's probably worth looking into other fields for tested and affordable solutions.

[@FM4AMGV]

The channels in cpi blocks are smaller, so its easier to clog them. That said youtubers using stupid colored coolants tend to have more problems

[@illitero]

Ziv Zulander I'm sure there's a LOT that I'm not considering concerning a few things, haha. Coolant concentrates are diluted, but even then viscosity isn't too much off from water. There are small hoses and channels that coolant flows through in the engine block and heads, but that's also around 10-15psi once the engine is under load. I know that I've read of people doing that before with ethylene glycol (green stuff) with results on par with PC equivalents, and that's not surprising. BUT ethylene glycol is no longer used by manufacturers because of the potential for corrosion if not regularly maintained. The only other thing I can think of that could be an issue is how certain plastics break down and become brittle when exposed to certain coolant formulas. Maybe somebody with a chemistry background can hop in and skool me on why my unoriginal idea is bunk lolol

[@CyberDenSystems]

illitero the only real breakdown issues you would have is with glycol based fluids, and petg tubing. The "G" in petg stands for glycol. So the fluid would inevitably break the tubing down. As far as soft tubing, that eventually starts to break down with whatever you put in it. P.s. also a car guy. Lol

[@timothygibney159]

They are not. Easy greed! There is a financial incentive for cheap Chinese manufactorers to fight over saving $.35 per unit. Also there is an incentive to make sure your product fails after 2 years so you go back to the store and buy another one. More money WahoO!! Car manufacturers have lemon laws and smarter consumers. PC users buy based on brand and love wasting money for that green Nvidia logo or an Intel CPU because it is about class and brand. In other words PC users generally are dumb and with no lemon laws and lawsuits it makes sense to screw consumers to make them repeat customers

[@Austin1990]

I have heard that anti-freeze works well in liquid cooling loops because it contains a corrosion inhibitor (at least I am told that it does). Corrosion inhibitors can be insanely effective. However, the inhibitor would need to be a a chemical friendly to plastic. I do not know what inhibitor anti-freeze uses. From a marketing perspective, anti-freeze is ugly. People want all these fancy colors and effects in their cooling loops.

[@ppn7]

problem with AiO closed loop : -You can't purge liquid inside like you do with your car and the coolant. Why car manufacturer advise you to change coolant like every 2 years ? Because they mix different type of metal. So if you don't do that with your car, radiator will start to leak, like an AiO problem even if you use only cooper parts, or only aluminum : -Radiators are solder. And the solder is neither aluminum, nor copper. It's something more corrosive than alu and cooper. So it could start to leak if you use only distilled water

[@twitchbook-1]

[@TK199999]

Galvanic corrosion is unstoppable, it's just property of metal when exposed to a liquid with a water base. Since its unstoppable, even if every piece is made of the same metal, in all custom and AiO liquid coolers mitigate the corrosion so that the system will have realistic/economical lifespan. That said there are non-H2O based coolants, but they still very expensive to make and are not used outside of high grade commercial or scientific server setups and even then many still use it only as a fire retardant.

[@cweber9112]

My question is why don’t they make an aluminum block for the cpu in AIO’s? Wouldn’t that be cheaper as well than to pay for a copper block? That would also fix the problem of corrosion. More curious than anything...

[@bigsportsman]

If you want another way to slow down galvanic corrosion add a small piece of zinc to the loop. Zinc will oxidize before the Al and Cu. When the zinc is about 75% gone remove what left and add more zinc.

[@Zrzyck]

Thats not how it works.

[@AtiCrossfireX]

I wouldn't stress it too much. Add silver to your loop as well. If mixing metal's

[@alecnordlund1679]

It's kind of a shame that they use aluminum since it forces them to use glycol. Often the performance decrease is caused by the glycol, as a solution (20-30% by weight) has a lower heat capacity, so less cooling capabilities.

[@DaemonJax]

In a copper + aluminum loop, the aluminum will corrode -- the copper will be fine. You got that backwards in the vid. Same with brass + copper loop, although the brass will corrode much slower than aluminum. Conversely, in a nickel + copper loop, the copper will corrode. Your best bet is to use all copper blocks and rads, then use brass fittings and copper plate them yourself with copper sulfate and a battery.

[@1222dss]

all rads are brass tanks with copper thins. Brass and copper corrosion is nearly nonexistent and will take ages to deal any significant damage even you gonna use tap water, let alone if you will use proper coolant.

[@datjamaicanjerk1230]

Love your content! You're always so informative and thorough. In my custom loop, I have copper waterblocks on the CPU and GPU with 2 aluminum radiators (one rad, I salvaged from an old AIO) and a silver coil in the reservoir.

[@TheRedneckAtheist]

Why do AIOs use aluminum radiators? Because aluminum makes a better radiator despite copper/brass being a better conductor, the mechanical superiority of aluminum(far larger tubes and much thinner fins) outstrips the dissipation advantage of copper/brass by a fairly wide margin. You want your loop to last longer, change the fluid more often.

[@a88pockets]

"we're gonna talk about galvanic corosion" Suprising you didn't lose me immediately.

[@TheSickness]

Aio‘s are throw away items and are not intended to be reused, reconfigured or anything, ideally from a company standpoint it were best if it failed 1 day past the guarantee period to sell you the next one. Anti corrosive enough is adequate for those

[@FrozenKopi]

cant the aluminium radiator be reused?

[@TheSickness]

FrozenKopi No, not really. On Aio’s at least they usually don’t have a reusable method of fixing other tubes back on to the radiator, normally they just little fixed barbs and cant fit G1/4 Fittings or barbs in a decent size for normal sized tubing. Sure you could diy it somehow. But as mentioned above Aio’s are a throwaway item and the connections are fixed on and the system is typically not serviceable (no decent fill/drain ports) So if a Aio sounds funny, cooling capacity degrades - it’s trash

[@williammurdock3028]

So if you used flex tube versus the rigid stuff with that TT kit, then I guess you would need new fittings to hook it up to.

I have a Custom loop with a fractal 360mm aluminium rad and an alphacool 280mm copper rad and Alphacool Crystal Red fluid. Should i change one of the rads out?

To be honest, the reason I don't trust AIO, isn't the material being used by it. It's actually the risk of leakage when used overtime. Hence, air-cooler FTW.

nickel acts as a suicidal cathode preventing the copper ri8?Like they use chromium and zinc in case of iron ?

[@dylanangel2870]

propylene glycol and water

[@ELGWAPITOZ]

which is better?

[@rheticus6673]

another thing that AIO do is use plastic fittings to eliminate electrical contact between the two metals

[@tiziofalzoni3998]

is there any AIO kit with copper radiator?

[@SuperTsogo]

damn this video is even nerdier than it has to.

[@alexandernguyen8203]

does the fittings for the loop effect galvanic corrosion?

[@1gatomon]

my thermaltake kracken 62 lasted only about a year and a couple of months and died.

Propelyne glycol

But we like it when you get scientific. It is 'Science Studio' after all. :)

If they use any aluminum in their base I can't even get their AIO I plan on getting whatever flagship CPU Zen 2 will have and a new motherboard and liquid metal for between the Ihs and the base because there isn't much point to delid on Ryzen CPUs.

You guys saying if i have full custom build with alluminium parts just GPU block is copper. If i use that coolant it will be okay? And i have 2 questions help me with them please; 1-)Do Alluminium fittings cause galvanic corrosion if other parts are copper? 2-)Brass and Cobalt mix in water cooling cause galvanic corrosion? Thank you..

I thought brass radiators were the norm in custom loops.

[@timballam3675]

Anti corrosive addertives? Distilled water is a good insulator.....

[@buckleyjteams]

Would putting radiator inhibitor into the system help?

[@buckleyjteams]

What I mean by this is a house heating system are very similar (apart form being larger) and when i fit a new central heating system we have to put inhibitors into the system

[@DIYTech21]

What about brass fittings and copper ?
