Danamics - a revolutionary cooling system?!

[Ket]

^^ Kind of reminds you of the Ageia PhysX cards, doesn't it? Ageia tried to be "clever" by making their PPU with a PCI interface, even though in the labs the cards were PCI-E. Why change the bus? Simple, so Ageia could make a "gen 2" of the PPU which was nothing more than the original design. If Ageia had gone with the original PCI-E design to start with, chances are we would all have a PPU n our systems today. I'll spare you the long story of why that would probably be true

Wait, so it's OK that they released a hugely over-priced, poorly-designed monstrosity because lab tests with PASSIVE environments showed more promise? That's lame. Did they really test it against other top performers in that same environment? Further, why would anyone pay that kind of money for a PASSIVE heatsink (which is almost by definition alone beat out by ACTIVE heatsinks)? Why did they feel that was a good idea?

The cooler was not designed for the people here at XS. I can understand your disappointment. They wanted to niche it to people who wanted a quiet cooler that could run in small or crowded cases where ambient temperatures are higher than average. They did test it against other coolers and found it to be on par with the competition with an edge in passive tests and high ambient temperatures. It did perform better than TRUE without fan, actually 9 degrees better with the overclocked processor in the Orthos test. That's the niche they wanted to find, unfortunately it is still too expensive.

A passive cooler makes no noise, an active cooler does. I thought that was kind of obvious?
People do pay for silence these days, quite a lot actually. This one is too expensive though.

Again, I know it's not easy getting funding, but if you design a bad product you don't release it - all that does is scam people. Given this costs multiples of what better-performing and readily-available items do, that's all it can be called - a scam. Not something that I consider good for anyone. No two ways about it - if you buy it, you're either dumb or you've been tricked by marketing designed to make you pay 4x what it's worth.

If it was truly better by, say, 3-4 degrees versus high-end air cooling then you may give some water-phobes something to think about. But you cannot defend the mass-production of this product.

It's not mass production, it's a limited quantity product. Mass production would be down-right stupid, I agree with you there. You should more consider it a demonstration of new technology than a perfected product.

They do make some very quiet fans these days - like, literally you-cannot-hear-them-in-a-closed-case kind of quiet.

It's a ridiculous niche market that would have the requirements:
1. High cooling requirement (induced by OCing only, really - stock coolers or cheap third-party coolers would be fine otherwise)
2. Case size is unusually small (inducing a high in-case temp)
2. No noise is produced (apparently meaning even yate loons or volt-modded other fans are too noisy?)
3. Refuses to try alternative cooling (ie. water) which could offer the same noise levels and work better by an order of magnitude

Basically they'd have to sell an uber-enthusiast priced product to a complete non-enthusiast... who likes to OC?


As long as they're taking niche market requests, I'd like to request a design for people that have the following design requirements:
1. High cooling requirements
2. Must operate with very limited oxygen availability
3. Must operate in low gravity situations gravitational aid
4. Must be able to withstand high levels of radiation bombardment


...but seriously, that's all beside the point because I (and others) stand by the simple point that the very foundational design of the heatsink itself is terribly flawed. Even if they do manage to sell a few of them, the fact is that they're about as good a product as the last batch of submarines Canada bought from England (they all leaked).

I'm confused how exactly the leaks are stopped, you said that the metal would simply plug up the hole, I guess it would be similar to blood clotting, but would the metal still not be exposed to the atmosphere?

I'd just like to point out I'm not really trying to defend their business plan, just telling you what I know.

They do, but fans wear and tear. Passive solutions do not.

Not saying it's a big niche or even a good one. Just what I have been told.

Their first attempt, they hope to do better with the next one.

The metal reacts with the air and become solid and non-reactive, and plugs the whole. The highly reactive liquid metal remains inside the pipe behind the plug.

If it is going to react with air, it will react with the moisture in the air, causing a large amount of heat, and hyrdogen gas (which will ignite). It wont simply become "solid" and inert. Also, there IS moisture in the air inside and around computer cases, why do you think insulation is required for subzero cooling? No to mention, it poses a risk if it becomes damaged while being shipped or stored, as it is more likely to come into contact with water (as well as moisture in the air). This is silly, I dont think you really understand the potential danger present with the use of NaK.

First of all, sorry for the late reply (Notifications from XS seems to come in groups of 40-60 nowadays and not directly).

I'm well aware of what happens chemically, my Master of Science in Chemistry should be enough to prove that. I wanted to keep it simple, because not everyone knows chemistry that well or don't speak English that well. Sorry if I was a bit short, but I've been working a bit too much lately.

The thing is that if there would occur a leak the hole will be small and the amount of NaK coming in direct contact with H2O will be quite little, it will then form KO2 that will plug the hole a bit like a scab.

This will of course also result in the formation of hydrogen gas, volume expansion and energy being released. This is course bad, but the amount is still within margins that it will not be harmful to you, the electronics may be damaged if the sudden leak is great enough, but that does seem highly unlikely with the testing they do before shipping.

The pipes are hermetically sealed and thoroughly tested before shipping. I don't think the EU would approve sales of a product that had potential of exploding and causing damage to the buyer. I would not be scared of having the cooler inside my computer. The build quality and quality assurance before shipping is quite meticulous.
