Captherm Systems MP1120 CPU Cooler"500X high heat compacity to liquid?"

[douglasjordan1]

I only hear of this because I am a follower of Bitfienix on facebook and the case used was a prodigy.. I am having trouble understanding this so if someone could clarify.

I found this

Still kinda stumping people but from the forum

The liquid supposedly boils at a very low temperature. According to one guy over on XtremeSystems, the liquid would boil simply on the heat your hand gives off. If that's the case, when it's super-heated on a CPU, it transfers heat away from the CPU very quickly. From what I understand about thermodynamics, liquid is an extremely good conductor of heat, which is why liquid-loops are so effective. For water cooled loops, the liquid remains in a liquid state throughout the process and is moved via a pump.

In this design, no pump is required, and heat is moved away more quickly. Think of it like a heatpipe on some really beefy steroids, but the liquid is far better, so heat transfer is more efficient.

I wouldn't be surprised if this is better than a custom water loop for temps. We'll just have to wait and see.

 

 

no temps, benchmarks.. or  ces coverage from anyone I follow. very intrigued

[Kilerbomb]

Woah that's awesome.

[That Norwegian Guy]

Hey this is not bad. Probably going to be ages before we see a consumer product though.

[Ineko]

Hm, interesting. I wonder what temps will be like.

[Razioer]

Well he says its multi-phased in the video, that means its a liquid-gas system.

Having a liquid cover the area where heat is absorbed, and then it turns into a gas an moves to the radiator by itself. Once there, it condenses back to liquid, giving off heat in the process.

 

Going from one phase to another takes a lot of extra energy on top of reaching the temperature where the phase change happens. Throw in the fact that the pressure inside that thing increases as temps increase, I suspect that they use that to their advantage, maybe it drives up the boiling temp of the liquid, increasing the amount of heat dispersed, and limiting how much of their compound can be in the gas phase, so the CPU is covered in the liquid at all times.

 

If they've found a liquid where the energy absorbed (and released when it condenses) is incredibly high, this could be very exciting.

I suspect it also adds some limitations on the orientation you mount this in.

 

 

Although, if the fan ever failed, I'd be massively paranoid about my system quite literally blowing up in my face.

I would love to get some benchmarks. It probably didn't get much coverage simply because CES is really big and there are tons of small booths like this one that no one ever has time to see. I do hope this gets off the ground and becomes successful though if it has really good performance that is.

There are phase change cooling solutions on the market now, I wouldn't be terribly worried.

OP, this is a pretty decent explanation of this cooling system. 

 

The phase change from liquid to vapour allows for much more energy to be absorbed by the fluid. This in turn with the high pressure of the system will make it very efficient.  Whatever fluid they are using it must really be efficient at heat transfer to allow for such a small radiator to condense it back down to liquid state.  You are right there will probably be orientation limitations.

 

In terms of it exploding, I have a feeling they have some sort of valve(s) that will open if the system pressure gets too high.  It's almost entirely solid state so the chance of failure will be very small.  I believe the fluid is entirely non conductive so it won't ruin your components if it leaks. My concern is with the lifetime of the fluid as it is continuously undergoing phase changes.

So long as it is in a completely sealed environment to avoid any matter escaping and no chemical reaction can occur, you can evaporate and condense something as often as you want. Think about refrigerators. They last decades, and use a phase-change cooling system.

Correct you are, but this fluid is different than those in refrigerators.  I studied something very similar to be used in solar water heating systems and one of the issues was a lot of the fluids used degraded over time. System was completely sealed as is this cooler (to the best of our abilities).  There is some "phenomenon" that occurs, I just can't find the article on it and the term escapes me.  Basically it has been observed in some new phase-change fluids with no real pattern and there really isn't any good explanation for it.  This fluid might not suffer it of course

It works exactly like a fridge or an air conditioner but doesn't require any sort of electrical energy except for the fans on the radiator.

[Andrew48]

I think silverstone had something similar

End of Q1 beginning of Q2. So before we see DDR4 or Maxwell.

 

 

Interesting idea, hopefully it takes off and isn't too expensive. Awesome to see a Canadian company pump out something sweet. Hopefully they don't get bought out by Google.

So, with the right fans, as quiet as a passive cooler with better performance than a water loop?

[gatecrasherlok]

I saw this video and it makes cooling a little more interesting. Nice to see that there is another option available.

[mgsstar]

Pretty surprised that this won multiple awards and never heard of it. But it looks pretty cool with the liquid flowing and can't wait to see the benchmarks. 

[Prophet of Entropy]

they just need to make some units that will fit on sli/crossfire rigs.
