Active Liquid Cooing vs Passive Liquid Cooling
- Thread starter life24
- Start date
I believe that this is passive water cooling, but I did not realize it was possible until I watched this video:
Active cooling means it uses fans to cool the radiator. AFAIK. And pretty much all water cooling is "active". Passive cooling would require a massive radiator like in the video above.

Jay2Cents has no clue on how to efficiently do LCS, without making it look blingy to feed his Youtube Subs and Channel.
Because that is the stupidest thing possible to do. Its beyond face Startrek Piqard Face Palming... Its straight up my doberman Face Palming with a big *Sigh*.
Why? because those rads are not designed for anywhere near passive cooling period.
Anyhow as others stated passive cooling means no fans running at radiator at all.
Your using straight convection.
Active cooling means you use a fan to actively cool the radiator.
Now that being said, passive watercooling is horrendous unless you plan it right.
You need a radiator with really low FPI (fins per inch) to allow convection to efficiently work out.
Hence if i was gonna passive cool, i would probably have used a MORA instead of those EK's.
Ive seen people near passive cool a mora, fine.
This is a MORA for reference:
Second i would of laid the radiators flat, and not horizontal so the heat can rise up more efficiently without resistance , and pool cool air from below up as it rises. Vs standing it up vertically, which again is why i said Jay2Cents a clown because he has no clue on how to efficiently plumb a system and is only after views on Youtube to feed his channel.
Because (Blingy > Efficiency) always to the new adopters, which is where Water cooling has regressed to, after it took off in 2010.

You are nit picking and ego tripping. His video was cool. And he's popular for a reason. Where's your YouTube channel again?Jay2Cents has no clue on how to efficiently do LCS, without making it look blingy to feed his Youtube Subs and Channel.

Again which he has successfully fed his subers and viewers...
If you think its cool, im happy you feel that way.
However me and a lot of other people think his builds are way too blingy, and he tries to push off being a expert when he seems to know very little about fluid dynamics, or even the rules of thermodynamics when doing a proper loop.
Or maybe he does, and he realized a proper build doesn't look blingy enough to make people like you think he's cool and not get his subbers.
But would i recommend anyone to copy his builds?
Maybe a couple ive seen from him would be OK, however when it comes to a more proper build i think BitWit does it better, and has a better ground on how to Loop things properly.
But thats just me....

I just like his channel, personally. Him, Linus, and Elric from Tech of Tomorrow are my favorites. I don't usually watch YouTube videos but when I do those are the guys I watch. I found the passive water cooling video interesting because I did not realize it was even possible and his results were actually stunning. In fact that level of cooling is probably what Intel needs for their new 28 core chips if they're going to overclock them.
Would a true passive loop allow a pump at all, our would you need to design it in such a way that convective flow actually moves your fluid? I personally find pump noise more offensive than fan noise, so if you could do a complete passive water system without using something like Novec that would be pretty neat.

OCZ Tony from a long time ago actually experimented with the idea on complete passive along with the pump.
The theory behind it was that hot water rises, while cooler water would go down.
So he had a radiator sitting up top and tested that concept.
It turned out in a case like this what is important is Volume.
But even then it was deemed a poor concept because in a closed loop system, thermodynamics fundamentally states that the carrying capacity of water is in direct relationship to the flow it.
That means, the more flow you have, the better cooling potential you get, until you reach a apex in that curve, where you start getting massive diminished returns.

Yeah, I'm not sure how you would end up building such a system. Delta T is going to be the engine that drives the flow of liquid in such a system, and traditionally you would want that as low as possible.
For a truly noiseless system, remote pump and radiators would probably be a simpler and more performant setup.
