News - Spinning Sandia CPU Cooler is 30 times more efficient

[Malphas]

Well I'm sorry but I still doubt most of you are actually qualified enough to really know what you're talking about (as in the majority of people here are not thermodynamic engineers for Lockheed or similar). That was my secondary point though, the main thing is there's not enough information here to make qualified assertions on its effectiveness, if you somehow think it is then again that kind of backs up my "don't know what you're talking about" point. No credible engineer would be jumping to conclusions based on a short video.

Also I wasn't attempting to kill discussion, kalniel, only point out the ridiculousness of statements like "Surely the fact that it's so shallow will reduce cooling effectiveness?", which are clearly baseless.

It's a discussion - not a jump to conclusion forum. Hence why I added the informal question mark at the end to prompt somebody to explain why it WOULDN'T reduce cooling effectiveness.

My statement has enough backing for a discussion:
- With a typical fan, air travels in one side and out the other. With this fan, one side is blocked by the CPU and hence I can't see how there can be significant airflow.

It was NOT a riculous statement and for your information I'm studying at the top university in the country for Electronic Engineering so actually, I think I'm qualified to make educated conversation about how it might work.

Your original post wasn't even an attempt to contribute to the discussion.

Well I found it a ridiculous and ill-informed sounding statement, to be honest, and I still do. And I don't think being a student/intern qualifies you of anything in itself, frankly. Sorry if you find that offensive, but it's just my opinion. We can agree to disagree.

[DeludedGuy]

Malphas, either way look at it, you are out of line. Yes, not all of us are qualified in this field, but we can raise questions so that we can be enlightened the users who do have knowledge in the field.

You don't have to be a professor in x to discuss x. There will be better and less-well informed people on this forum, some of whom can share their knowledge and enlighten the rest of us. Saying "you don't understand it so don't ask questions about it" is what is ridiculous.

So using your view point does that mean i cant,

Question the performance of a microprocessor in certain areas (e.g. performing worse in game x than game y due to different architectural designs) because im not a professor in semiconductor processing or manufacturing?

That is a bit of a silly statement/point of view, thankfully i know an expert in the semiconducting field but would i need to pass my question on to him and have him post it personally with his qualifications?. This is a discussions forum, its asking questions by everyone that makes it important... some experts can forget the very basics of their products so the target market arent getting a great product, it sometimes takes a person from outside of that field to pop a generic/low difficulty question to address something so simple!.

Also how does being a student/intern remove your opinion or ability to answer? Im pretty sure someone who is actually being educated in the field would be able to give a little insight. Might want to open up your mind a bit mate, let others question .

Thank you - Hexus cavalry!

I've got a strange feeling of deja vu..

Ah yes.. This time last year in fact:

Why is Hexus writing about year old news?

There's a new video from the company showing and discussing the cooler and details of licensees signing up to make these now. To answer some other queries: The linked PDF also says there are no issues if you want to use this cooler in any orientation. “Q: Can the device be mounted in any orientation? A: Yes—the air bearing assembly is held together by magnetic attraction (between the stator and permanent-magnet rotor).”

oooh... friendly in this one, isn't it?

It could be worse - you could have a Camel spitting in your face or a grumpy Elk molesting your car.

Another great solution for no contact cooling; http://www.greenlinecomputers.com/wp-content/uploads/2012/04/ComputerCooling.jpg

This is phenomenal btw. I will be getting my hands on one of these soon.

I'm not qualified in You but I am forming an opinion quite rapidly!

[Percy1983]

I am qualified and I think it should work great.

Problem is my qualification is in accounting...

Interesting concept, I do wonder why they've left the top open though and haven't ducted the exhaust either.

They could find a fair amount of pumping efficiency from the fan with good ducting as it's only essentially a centrifugal fan.
The air gap is going to be a limiting factor and will have to stay very small as conduction via air is so low. They wont be able to increase the surface area either.
I wonder how much of the heat is transferred by radiation (much higher factor with heat transfer through air)

Just in case anybody cared i have an meng in mechanical engineering specialising in thermodynamics and fluid mechanics.
