passive watercool loop

[Edmond Dantes]

i was thinking of doing a water cooling loop but a fan-less one. instead of rads i will use the passive tubes like Alphacool Cape Cora and even use those as the hard line tubes. what do you think will that work. maybe linus needs to make a video on that but make sure to give me a credit.

[SavageNeo]

I mean it will probably work. but how well? I do not know. the thing i know is that that is a waste of money since the cooling potential would be pretty bad.

[Eigenvektor]

They had something like this already

 

Ok, it's pumpless, not fanless. But a cooler without fans that simply relies on convection is going to be very inefficient. You'll need a much larger surface area.

GIVE ME CREDIT FOR AN IDEA

 

This has been done by many people, in different variations.  Anything can work if the science backs it (and does in this case) with enough money.

 

Or just get a full size car radiator, DIY to get the piping together, have enough pump power, and voila probably just as passively able to cool.

if you're not doing it "for the sake of checking the 'fanless' checkbox", you're wasting your time and money.

you need so much surface area to make passive cooling make sense, that it's really not worth the effort compared to a loop with some decent fans at minimum fan speed.

 

having that said.. you need airflow anyways to cool the rest of your components like VRM's, so a fanless loop is just an invitation for more problems to solve.

there is gonna be huge surface area though. there is gonna be a bunch of these Alphacool Cape Coras instead of rads like 20 pieces plus its all gonna be in the case with mad case fans. the idea im talking about, no one did it before i never seen it.  instead of the rads its gonna be a bunch of Alphacool Cape Coras connected to each other. even the tubes connecting the rads, its gonna be a Alphacool Cape Cora.

 

another thing that i have not seen, is someone using a aquarium water chiller to chill the water. maybe instead of the water reservoir, there is a water chiller.

im talking about a system that can be placed on a desk though. if you talking about DIY like that, might as well incorporate the swimming pool into the loop. lets see the cup/gpu heat that up.

or a river in the backyard (its on youtube)

 

If you want to spend your money on an incredible amount of tubes (get familiar with thermal equilibrium, heat soak, etc) do so Im just saying its not original, expensive, and no real credit to be had - real talk - if you got the money why not just post pics and a build log on it!

Basically this is another "Simpsons Did It" on Youtube.  Chilled water, ice water, peltier, fridges, freezers.

passive only on the loop, in a case with fans for airflow. or a open case with no fans at all. also what im talking about i have not seen. i seen people do bunch of stuff like a river even linus did a bunch of stuff, but what im talking about its something thats practical and looks good. something if you saw at the store you could buy.. i have not seen anyone build a custom loop using something like the  Alphacool Cape Cora instead of rads, and even using the cape cora tubes instead of the hardline or soft tubing. fans only on the case for air flow inside the case or a open case like a lian le 011 case with the glass taken off and no fans or glass on with fans for air flow.

 

the water chiller method is another idea that you can incorporate with the loop. i seen this done but it was a unpractical situation. with a big water chiller chilling water in a bucket and the rads are in the bucket. what im talking about is a small chiller that can be in the case all together part of the loop.

this is a unpractical solution though. he has pipes running thru the garage and everything. what im talking about its all in the case. also it doesnt look good with diy parts. what im talking about is all retail parts u can buy from the store and plug and play.

a fanless watercooling loop will be pointless and very inefficient... why? because of airflow direction... with fans built into your system, there will always be a predictable airflow direction in which you can orient your fans to help or deter your system (depending on which orientation you take)

the heat of the system is dispersed already by the radiator fins, the main purpose of adding fans to radiators is mostly to direct the heat to whichever direction you want that heat to go to... having no way to control airflow in a system where you are trying to regulate heat will simply result in warm air continuously recirculating within your system with no real way to efficiently disperse...

i guess. but those cape cora tubes look way nicer than a rad though.

yes they do... but you will still need fans to direct your heat to the closest exhaust holes in your system so it will not get recirculated... you can try it with your current system right now, compare the temperatures at idle with and without your fans turned on, and you will immediately see quite a difference in temperatures... optimizing the airflow path in the system is just as important as choosing the cooling solution for it (there are quite a good number of videos regarding this topic on YouTube)

i probably communicated it incorrectly, i was pretty much saying, instead of having ugly rads with fans on them you can use this and still have fans in the case for airflow, or use a open case. and even use these as part of the tubing.

What we are saying is, due to HEAT SOAK, that you will need an inappropriate amount of these tubes to have enough surface area to mitigate the fluid temperature.  A radiator, uses multiple tubes with fin stacks - which create a ton of COMPACT surface area.  You then cool this SURFACE area down so that it can CONTINUE to build HEAT SOAK into the materials.  You want to have enough surface area so that the eventual heat soak doesnt overwhelm the system.

 

So like...100 of those MIGHT be enough for a CPU loop, who knows - the best question you may have is - how many licks does it take .... I mean how many of these tubes does it take to passively cool.  Hell there may even be a math equation that could solve that if we knew the surface area of those tubes.

 

But can it?  Sure with enough tubes.  Should you - yes if you have money to burn, tell us all about it we love to see crazy shit here.  Can you?  Sure.  Do we think you are going to waste your money, time, space, etc - doesnt matter its your money, time, space, etc.

 

On that note - I do think these tubes are cool.  But for me, its not in my budget compared to the same price for 9 feet of tubing for an entire loop + leftovers vs 1 of these.

these tubes have fins too though i think this will work for sure but how well. plus it looks cool. these actually cost less then a rad. so its in budget trust. its got like 8 huge fins and 4 of those square things also there seems to be a bunch of science in the tube too.

Well, the science is nothing new.  Surface area and material type, heat soak, etc etc.

 

You do you bro - you are right, with the correct amount this works.  But the correct amount is going to be more than you expect.  You can passive cool a system, generically speaking, using a full size car radiator - in terms of fin stacks...you can do the quick visual equation.

 

Anyhow - you dont have to "sell" your idea to me, do it!  I think its neat, but extremely cost conflating for no reason beyond learning.  Which is cool too if you can afford it.

i guess your right. if its completely passive. but thats not what im saying there is still gonna be pc case fans, or a open case so there is air flow on the fins. im not selling anything. im just sayin its a dope idea. im not sayin you do it. it might be old science but its still science, and its in the tube. i think your just hating on my plan cuz i came up with it and u want to use it later and take the credit i swear, this is the best idea soon everyone is gonna make these tubes. btw your avatar is lookin real sweet

From what I understand, this is basically 1 step further than the "OMG I can use copper tubing to replace all the radiators" idea (which I guess doesn't need explaining that it doesn't work), and while the whatever thing that is being floated looks like it has more surface area than just copper tubing, it is likely to be far from enough surface to be functionally equivalent to even a small radiator.

 

Of course if you put oodles and oodles of this tubing into your case, then you may at some point achieve enough surface area, but then at that point it'll look so crappy and have such bad air flow that you might as well have put a radiator in.

 

As a side note, I don't really see how that tubing is any better looking than a radiator, but thats just my opinion.

you connect a bunch of them together. i found some PCs that did it and it worked.

So... basically barely keeping the components (i7 970....) at 80 degrees while using a radiator larger than the PC chassis itself, and you think that replacing some tubing with this stuff is going to be able to keep modern components (assumed) which are much hotter under control...Anyway, I have my opinions, but you are free to explore your ideas, keep a good log and let us know how it goes.

the guy did it and it worked. he reached those temps under stress. no one is stressing their pc like that. dunno why everyone is hating on me over this. all im sayin is it works and it looks cool.
