Samsung tired of people tearing into the Note 9 cooling, shows us exactly where the carbon is
The Galaxy Note 9’s cooling was a hot topic long before the phone was officially announced, but when it was called Water Carbon Cooling System during the release event, it really got people’s attention. Naturally, as soon as the phone reached tech reviewers and consumers, people were eager to find out exactly how it works. Multiple Note 9s gave their lives in the name of science and the consensus among the examiners was that while there was water in some form in the cooling, carbon is nowhere to be found.

Well, Samsung had seen enough guessing work and decided to set things straight once and for all. In a post on its website, the cooling system of the Note 9 is explained with visual aids and simple language.

The “Tech Lab Notes” confirm the water part of the system: it turns to steam from the processor heat, travels through the porous filler of the copper pipe and turns back to water on the other end, once it has cooled down enough.

The Carbon comes into play as a Thermal Interface Material (TIM) that sits directly on top of the chip and helps conduct heat to the copper thermal spreader. According to Samsung, the carbon fiber TIM is nine times more conductive than silicone, which is why it’s the preferred material for the job.


Considering the size of the processor and the thickness of the carbon layer (likely measured in microns), it’s not hard to miss, especially if you don't know exactly where to look for it. But it is there, it helps with the cooling and we’re glad the dispute is finally settled. There is carbon and there is water, there are no marketing tricks or gimmicks involved in the Water Carbon Cooling System of the Note 9. Case closed.

Both PA and Samsung are right Samsung are right to say water carbon cooling system Its a cooling system with water and carbon But its not water cooling, which many others have called it Don't believe Samsung has called it water cooling They've been specifically careful to say water carbon cooling system Its many media sites and fans who need correcting (and other OEMs who say water cooling for their heat pipes/vapor chambers)

Heat pipes and vapour chambers are not water cooling or liquid cooling They are liquid/vapor heat transfer systems Or thermal spreaders as shown in this graphic Same applies to heat pipes/vapor chambers in other phones e.g. Google, Huawei, LG, ROG, Razor, ... To be fair to Samsung, water carbon cooling system is actually accurate But water cooling is not So Samsung aren't being as misleading as most OEMs who straight up lie and say water cooling

Edit timed out Water carbon cooling system is actually accurate Its a cooling system with water and carbon But people who say not water cooling are not right

Well, it's not like it's a full blown gaming PC with room for an actual water cooling system.

So that gives other OEMs the right to lie and call it water cooling? Not in my book Its if an OEM advertised having a full frame sensor when theirs is 1/2" Oh its OK because its not like it's a full blown camera with room for an actual full frame sensor

Yeah whatever, the thing it's that 999€ for the crappy Exynos version it's ridiculous. It should be cheaper than the snapdragon, cause it's way worst.

Not so sure about exynos being worse:https://youtu.be/B65ND8vUaKc

f**k, forget about speed tests, what about gpu department, adreno 630 it's far better than Mali g72 mp18, for god sake even adreno 540 it's far beter than the Mali on the note 9 exynos.

If playing heavy games on your smartphone is your thing, then yes, exynos with mali g72 mp18 is not as good as adreno 630.

Here we go Exyons better than snapdragon https://youtu.be/rZ-mxershFE

There are more fun things to do in life than play games on smartphone. That's why GPU is mostly irrelevant for me.

If both side of the wafer is producing heat. How is the THIN carbon cooling system cools down the processor to its normal operating temperatures?

Silicone is a poor heat conductor, no wonder carbon might be better but it's not better than copper as a conductor of heat at all. Imo, Samsung used marketing words an got caught and now are trying to bury that. Carbon is very very poor heat conductor, it's more of a shield like wood than it does to help remove heat.

Saying carbon isn't saying anything. What's a diamond made of? Diamond is over twice as conductive as copper. And you don't slap two pieces of copper together and expect good conductivity. They're using it as a gap filler. Unless the parts are smooth down to the atomic level you're going to need something to keep the air out, and that's where they put the "carbon". Their engineers aren't stupid. They didn't spend money to put an insulator in their product. And it works well so they did something right. I trust them more than anyone around here.

Let's not forget that Graphene is also a form of carbon that is far more conductive than copper. Carbon has so many forms and can be found in millions of different compounds that simply saying Carbon doesn't even narrow the possibilities

Sure. They are feeling it.
