its actually a speaker

Hhahahaahhaah

Oh yea, another useless thing they added I guess, the brushless motor's PWM duty cycle and mosfet frequencies are modulated with varying music amplitudes/frequencies. I.E. Fan is singing

Cooler Master didn't show jack so far. The first commercial attempt will be in mid/late 2015. It was Coolchip themselves.

Kawayolnyo Theryre apparently a division of CM.

Yeah the actual product was shown off in the CoolerMaster suite. Both Linus Tech and JayzTwoCents did videos on the cooler from the CoolerMaster suite. the final commercial cooler will be sold under the CM brand.

Applebloom Nope. Not at all. Coolchip basically just rented Cooler Master's suite on CES, to introduce it's technology, while Cooler Master made a contract with Coolchip to release the very first commercial version of the product utilizing this technology. But Coolchip doesn't belong to Cooler Master. They just have contract to release first Coolchip-designed cooler under the Cooler Master's name/brand. David Dewis Yes, they did rent Cooler Master's suite's space to showcase their product at CES, but they don't belong to Cooler Master. They just have a contract with Cooler Master to release the very first commercial version of this cooler under the Cooler Master's name and brand.

Kvarnholmen. The fan blades may look the same, but the underlying technology is completely different I believe.

***** Yeah, maybe the 1/10th of a mm with some "cold plasma" like energy transfer (compressed air) could do the trick. But still, its too sci-fi for me. Even ordinary coolers need thermal paste to fill in microscopic cracks... And I stand by my deadloop thing. I see a high potential of air getting re-used :/

***** You can easly test this on your own computer: take off you cooler and install it without any thermal paste. Run some temp program. Install the cooler again with thermal paste... compare temps with and without paste. There is also a VERY VERY thin layer of air there. Ok, to give some thought to it: the "cold plasma" thing i mentioned. There could be a channel for heat-energy through high pressure gas. Maybe even motion can contribute at "grabbing" heat and transfering it. But still. I think such transfer is very inefficent :/

I agree, when I was watching this I thought to myself, how the hell is the heat from the chip getting to that heatsink, since it's basically floating above a base plate... Or are they planning on floating the cpu around too lmao xD

exactly what I thought

Your fans are plastic and spin much slower.

ISFiYIywAFIBc6qAIIIIIIIIIIIIIIIIQrXTJiCtY3Asd4WF did you watch the video? The heatsink/fan spins at 2000rpm. cpu/case fans spin at upto 3000rpm. most commonly around 2000rpm for high static pressure fans. And so what if my fans are plastic? I can buy a 212 evo which has a smooth finish on the plastic and it'll still be covered in dust after a few weeks or so.

It's in the design. The typical fan blade cuts through air, each time pushing a slice of air forward, perpendicular to the blade, this creates lots of friction and static electrostatic, trapping dust on the blades themselves. With this design, air is centrifugally flung out of through the gaps between the blades with higher velocity so even at 200 rpm, the exit velocity is much higher. But I do see two problems with this though. First being that the viscosity of the air doesn't change and fluid dynamics would suggest that a layer of turbulence will still form along the surface of the blades, trapping some dust along with static created from the friction. But because the velocity is much higher, larger dust particle should be pushed through more easily. Second, dust have to land somewhere, if not on the blades, then on the heatsink down the line. The way the fan is implemented (ie, by Cooler Master) would mean that dust fling off the fan will just get caught by the heatsink. Another interesting thing, however, is the switch in how air is pulled into the fan, from a planar nature to a turbine-ish system, this would make it easier to filter the air beforehand if needed.

Get a proper case with good dust filters. I've got no problems with dust in my Fractal Design Define R3.

I recommend water cooling a watermelon

Zajebex i came here to find something to cut my watermelons. and found it.

That's exactly what happened, then it grew sentient and decided to go where boldly no fan has gone before.

i....is that an Amazo reference?! o.o

Coller Master use that. I forget the name of it but you can find it.

Cooler Master has a similar technology that it's working on nowadays.

Thermaltake Engine 27 1U

It works independent of orientation The most common misconception seems to be that the Sandia heatsink only works in a horizontal orientation. In the KZfaq video released by Sandia the cooler is demonstrated like this, so it seems reasonable to assume the air bearing heatsink only operates on a horizontally plane. Yet as we all know, most computers have the motherboard vertically oriented... According to the developers, the Sandia cooler is in fact orientation agnostic - meaning the air bearing is not affected by gravity and the spinning aluminum fins will operate vertically, horizontally, upside-down or at an angle. A compression spring is used to hold the impeller and base together, not gravity.

even if orientation were the problem, it wouldn't be too difficult to setup an appropriate mounting sollution

magnets

those might actually create to much distance...

Hey, alysdexia? Hard drives work sideways because they have **a solid shaft running up the middle**. This thing is floating on a cushion of air. Trying being a nicer person next time. teh_r4serei says Sandia released a statement somewhere else saying the device uses a compression spring to hold the rotor in place, and it seems reasonable enough to me that I'm not going to double-check his source.

+No Lucks Given , cooler master redoing it and probably making mad bucks on it

denisgsv well hopefully normal people like me can buy them wothout spending too much

+No Lucks Given its all about conspiracy, some kind like Gas Fueled engine VS Electrical Engine

***** Well I hope you are wrong, because I wouldn't mind something like this. That being said a simple closed loop has so much performance per dollar, what really is the point right?

www.google.com/#q=cooler+master+sandia+cooler&newwindow=1&safe=strict&tbm=isch

I know 1one negative, if you toch the coooler with your finger you will suffer a lot of pain

do you realize that it usually takes around 10 years for new technologies to reach the market? That said, they compare it to regular heatsinks, and not stuff like cpu tower coolers with heatpipes, so I doubt they'd prove beneficial in regular computers for quite a while. Application in the industry is probably already happening at a small scale.

10 years? were have you been living? As far as I know most great inventions blew up on to the market 2-3 years after first prototypes.

Dmitri Felbinger that must be why we had heatpipes in computers in 1960.. OR, we didn't, which shows that in some cases it takes a MUCH longer time. especially when it is things that were made for industrial application and not consumer products. You can expect that this will be in some industrial use now(which would then be considered a corporate secret, and you wouldn't know about it), OR within a few years, when efficiency has been further improved. And you can expect it to take a LONG while before we see these in consumer products.

Dmitri Felbinger also in most consumer products you will probably never see this, since piezoelectric fans will probably be available before this, at least for laptops. There are already being researched on by Fujikura etc. which make a large amount of the cooling systems for laptops now. watch?v=Hm5fXj-hUpk#t=191

Complexity itself is complex. Not being math able I cannot have a sufficient grasp on it. Neither can the teleprompter and cue cards team makers.

I did my NDI testing there at Sandia National Labs and there are some really good people there. I think they could have emphasized a little better how this is a little more of concept than FINAL design. It does these men and women working there a great disservice.

LimitedWard He obviously didn't look to far in the "literature" because Nikola Tesla describes the "boundary effect", adhesion etc. in his Fluid Dynamics and Tesla Turbine Patents, that was in 1909.

LimitedWard 2015 they already did one for inside a computer... it work pretty well and quiet

+enzawashballs Tesla talked about diminishing the boandary effect by using a rotating object? Or did he just describe the boundary effect in general? Also, do you know why so many uneducated people think Tesla is hot-shit? No mention of Maxwell, Newton, Euler, Helmholtz...Maybe because they are also conspiracy nuts? I mean, Tesla is definitely a smart guy, but he is a dwarf of a genius compared to most other famous scientists. It's very strange

ab cd Maybe because all modern scientists have to refer to Tesla patents, not Einstein's, not Edison's, not Maxwell's, not Newton's, nor Euler or Helmholtz. Thats unless you include Edison's rock crusher and electric chair, using GE's A/C patents. (The electric chair used by Edison was not Tesla's A/C patents, GE's A/C is different patents) And GE's initial A/C patents didn't work so good electrocuting people.

Good reviews and very small

I have tons of dust on my fans. Just cleaned some off today.

im lucky to try out server grade stuff certificated for 24/7, and thats cooler is spins at 7000rpm, louder than a vacuum cleaner, but able to blow the dust off from itself and the heatsink fans (the normal fans i tried are dusting and needs regular cleaning ~1500-2500rpm)

Either that, or matte plastic surfaces designed to constrict airflow along the axis of spin aren't comparable to smooth aluminium surfaces designed to encourage said airflow.

The difference probably isn't the RPM, but the fact that those gaps are so narrow and there aren't diagonal slopes. The air is forced through at presumably higher speeds and more uniformly (less weird aerodynamic effects happen at the blade surfaces and allow dust to collect).

I we seen 8000 rpm fans with dust on their blades 2000 rpm stands no chance

@krap101 The insulative air as you call it is reduced by the spinning effect of the central column aka a mini vortex or mini tornado. Cool air drawn in from the top hits the base expands and is expelled by the fins. Like stirring a tall glass of water. the faster you churn the water in one direction the deeper the vortex goes relative to the rate of initial turn.

There's no hole at the bottom. Also look up what a boundary layer is.

krap101 is talking about from the stationary eg. CPU mounted part to the fin.

I have the same question. The way Cooler Master uses this (in another video) is to have another heatink surrounds the fan.. same old design we see in stock gpu cooler.

Amaroqdricaldari We have the technology.

Would be insane cooling for small form factor. Maybe around $150 for like 200w tdp.

+GoogleMinus listen to what they say in the video; "nearly noiseless with a ducting cover", its a prototype!

mtohrw Nearly noiseless, so it will be very quiet but still the same sound.

GoogleMinus that, we do not know. The sound it does in the video seems typical to an early stage product without proper shielding. What I'm trying to say is that we dont know anything except from that they more or less promise it'll make less of a sound than regular fans. Modern quality regular fans hardly makes any sound a part from the "waterfall air noise" they speak about in the video so we can assume it has a pretty attractive performance to noise ratio. also, you have to take into account that due to it "hovering" it wont cause vibrations which causes A LOT more noise than most people think.

mtohrw The difference is with regular fans you can put rubber vibration isolators on the fan contact points because it doesn't need to conduct the heat...

L

This was 9 years ago dude

exactly, this is the biggest question. it's like putting a heatsink without thermal paste.

@Hoshimi Draws because heat transfer coefficient of air is vastly less than that of metal, normal heat sinks have very large surface area and a thermal paste on the contact pad. even a thin layer of air at the contact pad significantly reduces the entire device's capacity to transfer heat, that's why traditional heat sinks practically stop working if you leave a gap in your thermal paste layer. in this proposal there's an air gap without thermal paste at all.

shhh

8 years on are you still waiting?

Its a blower with extra surface area xD You have one in your ac units. There is no innovation here xD

Richard Smith don't really have ac in the uk but i get what you mean, they have these type of fans in many things like hoovers and water pumps just with different blade designs.

Richard Smith The innovation is using the surface area of the blades to dissipate heat. Instead of using a blower and a heatsink.

Patrik Manni I dont understand how exactly that works with a pocket of air between the processor and blower tho... that would make an excellent insulator, the opposite of a heat transference medium.

On the contrary, the speed at which it's spinning brings the size of the gap down tremendously, making for excellent heat interchange. This is a really cool solution to cooling, actually. But there are some big engineering hurdles to get past. Like how to make it work when it isn't standing flat on a table. And how to best use the blades to bring air further down the impeller without creating lift, like most blade solutions would.

Dust gets stuck on both heatsink and fan, some on the underside of the blades and some on the cutting edge of the blade but also on and in the heatsink fins. It's why i usually keep a small toothbrush in my computer kit, so i can get between the blades and brush the dust from there as well and a can of air duster for the heatsink.

@QuantumBraced most modern fans are plastic. This is Metal. Less grip for dust particles and or static resistance may also inhibit the dust. If you run a metal desktop fan and a plastic equivalent and the same speed for the same length of time in the same environment you will find the plastic one gets clogged/coated easier / faster than the metal one.

Smoother surface. It's like a pearl forming in an oyster or a raindrop forming in a cloud. The more polished the metal is, the less chance particulates will have a chance to grip on to it.

Yes, that's why they call it the dust devil.

Always. Just ask the wifey

might it be dual too? "duel RAM/engine-bleed air cooling turbine " ..... chose your weapon !! LOL

That's the main concern I've actually spotted so far. Modern top-of-the-line god tier air coolers like Noctua's NH-D14, Cryorig's R1 Ultimate, and other massive towers, have their fans oriented that way so they exhaust the hot air at the back of the case, where the actual exhaust is. This technology's design (and even Coolchip's improved model's), on the other hand, obviously just throws the hot air out everywhere, in all directions, which is an actually extremely bad thing if you have shitty air cooling chart in your PC case by default, and especially if you're putting something like this in a SSF factored systems like ITX or HTPCs. That's a massive problem. And how these guys (or hell - even Coolchip itself) are going to fix this problem, if they're able to anyway, which I doubt, is beyond me, until I'll see the goddamn thing working by my own eyes, in a consumer build.

Good question, since it's powererd by heat convection i think a diferent design based on the same principal would be needed to work on it's side.

Kawayolnyo Most non reference design GPUs also just eject heat everywhere, as long as you have good airflow through the case it shouldn't be a problem. I'm more concerned about dust getting stuck in the air bearing. (I know he talks about dust but he doesn't mention the probablility of dust getting stuck in the bearing).

Denmon >Most non-reference GPUs also just eject heat everywhere You're saying this in such of a tone like it's an actually alright and absolutely tolerable thing for hardware manufacturers to do. Which it isn't.

Kawayolnyo You're completely missing the point here though, as long as you have good airflow over the mobo area most heat should be exhausted anyway. It doesn't even take much, two fans in the front for intake and one in the back for echaust will move enough air that whatever heat gets blown around in there will be exhausted without much issue anyway.

Any day now lol

the stationary base is mounted to the CPU, and the thin layer of air transfers the heat to the spinning heatsink.

The air bearing is just as efficient a thermal insulator as the boundary layer on a conventional heat sink.

That I do not understand. How can air conduct the heat efficiently to the fins yet we need massive amounts of fins to remove that heat from them.

Thank you, I was looking for this answer, will look it up some more.

kyle krone lol i thought it was me

+BlackWing Cyper I thought these were ads xd

You mean "efficient"

haha yea that feel like a dumb-ass for not proofreading that

taitaylor86 :D

***** I'm planning to build a horizontal PC (the true desktop computer), either by modding an old case, or with something like a Node 202. Or maybe even build it in my broken Xbox 360's case. But I really need something like this, a low profile cooler with the highest TDP cooling.

I forgot to mention that I'll be building my next PC in 2017, when AMD launches Raven Ridge. So I'm hoping by then they would have launched their cooler and would have an AMD mounting solution. I don't intent to go that extreme with liquid cooling, I prefer a low profile heat sink and add small case fans for airflow. If it can run under 65°C, I'm happy (I don't live in a hot climate).

***** Yes, my current build is an unlocked and overclocked Sempron 145 (now dual core 3.2 GHz), 2 GB of RAM and an Asus 6670 GDDR5 edition. For my small gaming rig I'll use the best 65W APU with highest clock RAM and no dGPU (anyway, an APU's iGPU with HBM will be an improvement over my 6670). I like small and silent builds. I had a monster tower PC with FX 4100 (OC @4.2 GHz and turbo to 4.4 GHz), 8 GB of RAM and the same GPU, but sold it and bought a Windows tablet (Toshiba Encore WT8-A - which I'm typing from right now). It was pretty noisy because of case fans and it ran pretty cool (never exceeded 58°C). But I don't play hardcore games anymore, just light things like Asphalt 8. At first, I was pretty tempted to buy an Intel Skull Canyon NUC and use AMD X-Connect, but I like building PCs myself (I feel more accomplished). Anyway, thanks for your feedback. Much appreciation. :D

***** I thought I said I _had_ a FX (I sold it to buy my tablet and kept my old rig). I'm not really planning to upgrade the Sempron, as it has 2 GB of RAM and it's motherboard has a broken SATA port (for whatever reason, it won't recognize anything plugged in it). Also, being SATA II it won't help, since I want an SSD. Upgrading it might save me some money in the short run, but I plan to do it for the long run. Indeed, the Athlon II x2 have great unlock rates, but my motherboard was cheap to begin with, I'm not really trusting it anymore. Also, it's HDDs are dying as well. It has a 320 5400 RPM laptop HDD and it loads very hard, like 10 minutes to boot and use Windows 10 (it was the same with 8.1). When opening apps, it takes around 2 minutes to open things like Opera. After the apps have been opened, they run fairly well though. On the bright side, it's other 80 GB 5400 RPM laptop HDD runs Ubuntu and it's pretty fast except for boot times. After boot, it loads things almost instantly (and this one is at least 5 years older than the 320 GB one). On the bigger picture, I'm not living where my PC is anymore (I moved in another city), so I'll make sure that PC is running smoothly for my mom to use a small accounting software in Windows, while I build another rig (and I want to get a bigger resolution and dimension monitor. I used 17 inches 1280x1024 and now I want something around 22 inches or bigger 1080p or 1920x1200 (I like 16:10 aspect ratios). My plans are for the best 65W Raven Ridge APU (hopefully it will have HBM), 16 GB of DDR4 3200 MHz or higher (I'd love the juice of up to 4133 MHz RAM, but I'm not sure the motherboard will support it), a mini-ITX motherboard and a 256 / 512 GB SSD (if the motherboard will have M.2, I'll get something like a 64 GB for the OS and a 256 GB SATA SSD for storage), a low profile air cooler and 1 or 2 case coolers, depending on the space of the case (and some dust filters while I'm at it). No dGPU. Money aren't really a problem (of course I can't afford $3000 builds, but something around $800 is fair enough for me to spend).

***** Well, I kind of want a 40 in TV :D. I plan on 16 GB just for quad channel that I hope Zen will support (4 x 4 GB DDR4). And hopefully there will be mini-ITX motherboards with 4 DIMM slots (there are some on Intel's part). Also, quad channel is _almost_ double the bandwidth of dual channel DDR4, which will help an APU's iGPU a lot. I'm hoping it has HBM, but I too take it with grains of salt. HBM will drive the cost a lot on AMD's side, so I don't think they want to risk it. Quad channel DDR4 3200 is ~100 GB/s bandwidth, which is very close to what 1 stack of HBM gen 1 can achieve (128 GB/s). Paired with something like a 4 x86 cores and 12 gpu cores (for a total of 16 CU), without taking into consideration Zen architecture and Polaris improvements, I think 1080p high settings AAA gaming is achievable without anti-aliasing. Also, being sick of 2 GB of RAM only and seeing that games these days require 8 GB of RAM, I kind of want to future proof this build. I know it's overkill, but I might run some VMs on it (my main OS will be Linux), so 16 GB might be worth it (considering I won't be changing this build for ~7 years).

it's silent as my ass.

***** And you may pretend that you don't fart, but you do.

Apparently you didn't catch the part about boundary layer effects. Maybe you didn't listen at all?

cheif10thumbs I did. I'm not saying that the connecting part will be making the noise, I'm saying that the blades will cut the air and make a familiar airy sound.

jusk i think you are right because the video at a certain point was claiming it could potentially be 'silent' in it's final itereation, though overall in the video I think they were claiming it is significiantly quieter than traditional fans, while also being more efficient at cooling - not that it would be completely silent.The CoolChip cooler prototype that was shown at CES this year in this video: kzfaq.info/get/bejne/l86XobmjurLVhac.html, which liscences the Sandia technology claims to be 20db quieter than a commercial fan at the same RPM while removing more heat. There's various reports online about this prototype which confirm that it does seem significantly quieter.Not really fair to nail the design by interpreting the claim of being quiter as claiming it will be silent, and that accumulating less dust as accumulating no dust. I'm excited about a consumer cooler that is 20db quieter, while being say 50% more efficient.

The air gets heated and moves outwards through natural convection. It then blows air through a heat sink that surrounds it.

considering most cases have a fan positioned to dissipate cpu heat I imagine a blower like design could easily direct the air out the back of the case the same way gpu blower fans work?

***** Correction: the air gap acts like a very, very bad thermal conductor. That's why we need thermal paste in conventional CPU coolers, where the gaps are in micrometers.

My guess is that the fan they're using is a PoC (Proof of Concept)

The sound is explained in the video, that's the noise any motor makes when you take the shrouding off.

It's loud... anything turning that RPM is loud period.. good luck.

ISEE YOU Not necessarily.

Hλwk978 Yes.. actually. Been building custom PCs for 15 years.. been through a lot of cooling solutions from back in the day when pond pumps were used for water cooling. I am sensitive to high pitched noises and you can tell how loud it is in the video......

He even says it's the motor making the noise! When he let's it coast it is no longer being driven.. well DUH its going to be quiet!

Not very humble are you.
