Spinning heatsink

thats a nice find, but i doubt they will introduce them to the market anytime this or even next year, besides i wouldnt want something like that just spinning around in my case,
 
They show some rigs there with what looks like a Noctua heatsink(0:50).. They must have done some kind of comparisons... Though, I wanted to actually see some results... :\

explain?

Maybe better for OC? (ie open rigs?)

Looks quite intresting. But as it isnt on the market yet, i doubt tom will get one anytime soon.

Still im kinda worried how this is installed. As it should not directly connect to the CPU the installation might come uber-complicated..

Ah okay, so the baseplate sits directly on the CPU ?

Yeah it does look like the alphacoolpumps lol.
 
That's what it looks like.
I think the fact that it's spinning also creates some air which cools the plate, as well as the fact that hot air rises and the fins are being cooled from the spin...
Not sure how effective it will be on a CPU, though if they say it works well with LED lights (and they get pretty hot) then it might be good...
We'll have to see some real results.. It's just a matter of time before a PC heatsink manufacture decides to do something similar...
 
:(

Oh well...

Yeah, I agree that having a rotor would generate noise, though I do wonder how loud it will be. At 3:04 they say "Level of noise is pretty impressive."

I am quite disappointed. I need more results.

Some more digging showed me this:

It looks like they are testing it on Intel CPUs : https://ip.sandia.gov/techpdfs/Sandia Cooler-Fact Sheet for the Microelectronics Market.pdf
With their presentation they say "very quiet" (https://ip.sandia.gov/techpdfs/Sandia Cooler presentation.pdf)
^ page 9 shows cutout... with Thermal pad very similar to CPU heatsinks...

Detailed report: https://ip.sandia.gov/techpdfs/Fundamentally New Approach.pdf

Oh well, I guess we'll see how long it takes to bring to market, with reviewers testing it out..

P.S. Sorry, I'm sounding like a marketer :\

edit: Not to talk about the dust that would get in the air gap... Going to a real pain to clean...

Although it may be a little noisy, it is an interesting new way to cool a CPU. If more development is put into this, maybe we'll be seeing such things in PCs in the future :)

LOL I dont think I want too..... spinnning = motor = noise. It will be noisier than a fan.

I don't think it will though tom.

Looking at the diagram shown, its more of a passive heatsink. most of the noise in PC is down to the sound of the air being forced through objects, Heatsink, rads, grilled fan mounting points etc. The Brushless motors nowdays dont make a sound. Even the hefty brushless motor that powers my converted HPI baja doesnt make a sound. the only sound you hear is tyre noise from the friction.

By looking at the drawing it seems as though all this does is spin in order to create both convection and conduction.

So take for example.

The heat from the cpu travels to the base plate and from the base plate to the rotor. the center of the rotor is the hot area and the edges the cold. With conduction the heat will travel to the coldest areas in order to expand thus taking the heat away from the center. and then as the edges of the rotors begin to heat up Convection takes over, and the heat from the edge of the rotor transfers into the cooler air and as the air gets hot it rises out of the area. thus cooling the edge of the rotor in order for the Conduction to continue.

It is a great idea to create a silent running heat sink. However. my concerns are. wile yes it will work. The worry is Just how economical the the heat transfer will be, Also as said about air noise. that rotor is cutting through the air. But its a case of balancing air penetration with low noise levels.

I am intrigued by this though. Its great to see people coming up with new ideas. if it turns out to be terrible. Well none of us loose anything.
 
I don't care about the 'hows' and 'whys' right now.

If it's cheap enough, cool enough and quiet enough - I'd buy it.

Two out of the 3 probably won't be a reality.
