Sandia Develops Amazingly Efficient CPU Cooler

But will it blend?

i do not know that this is viable as a motorized rotating unit. where is the wired plug going to come out from and how do you keep the wires off this spinning saw blade?
unless it comes from the underside or the center of the hub and straight over the top, which if it came out from the center out the top how long do they make the cable to reach the various positioned plugs on each motherboard and how do you keep it from getting tangled or chopped off by the rotating blades of the heat sink even if it has a plastic sleeve to brace the wires and keep the wires erect and off the hub.

that part of this has me puzzled and i don't wish to take the time to make my ramblings make sense to every one.

[citation][nom]IndignantSkeptic[/nom]I wonder if they can put this technology in smartphones and tablets because then those devices would be able to generate more heat which means their processors can run faster. Correct?[/citation]

That is correct but much besides the point of a mobile device.
You want less heat and no active cooling because it's violently murders the battery life.
The reason why mobile devices will always be behind in terms of performance is that they are using (arguably) old school tech with bleeding edge manufacturing processes and software.

Case in point:
Mobile phones use RISC cpus that run typically between 550mhz and 1200mhz (some now with dual core) and have and almost a yearly OS overhaul.
Phone battery: 3.3v, 2100mAh

Desktops and laptops typically use (arguably) inefficient x86 chips at much higher clock rates, dedicated VGA, mechanical HDD's with tons of storage and a 2-3 years between OS overhauls.
Laptop battery: ~14.4v, 4400mAh


Mobile devices can typically spend 12 hours or more of constant normal use while laptops have typically less than 4 hours of normal use despite having a higher battery capacity.

The main focus of phones and tablets are not raw performance but rather the energy efficiency. Unfortunately cooling solutions have little to do with these devices as the hardware does generate much heat. If it does then think of it as battery juice leaking out. You don't want to have heath to begin with and even less have to use battery juice to disperse it.

Good Tom's didn't post their youtube video! kkkkk
Looks promissing, but it will for sure slice your finger out! ;p

read the original article, after plowing thought it, i came to the conclusion the it is a great idea for a/c units.

because the fan blades tend not to foul, and compared to a radiator that is clogged this is alot more efficient to less maintenance to keep at top efficiency.

I don't think the idea is to blow the air down on the supposedly copper plate. The idea is the temperature to be transferred to the upper aluminium part, although I don't see how exactly /through that thin air gap???/ where it's taken from by the air, blown away through these curvy channels.
And another problem is that this hydrodynamic thin air layer bearing works only if this thing is with a perfectly vertical axis with the copper base down /can't work upside down/.

Interesting tech. This looks promising.

 

[$hawn]

@husker According to newtons law of cooling, higher the temp difference, faster the rate of cooling. So basically thing thing will work even better at higher temps!!

They would be better off stacking cpus on fluidic chips cooling them if you want to save space thats way to go.

 

[gaborbarla]

[citation][nom]nieur[/nom]great design. hope they don't patent it[/citation]

lol you got really voted down, I guess people don't understand that if it get's patented then we will likely not get to use it for free. Perhaps we would never get to use it.

 

[draphius]

this cooler spins at extremely high rpms, somewhere above 6K if i remember right. this is meant for enterprise solutions and not the avg consumer. imagine if a bearing failed in that thing... pcb shrapnel has to be a pita to get out of your flesh

 

[Guest]

does the author know what absolute thermal resistance is? 0.05'C/W is much better than 0.2'C/W, not a quarter of it.

 

[Guest]

That compact design might have some implication for those noisy ITX computers or 1U/2U servers. Who cares if it doesn't cool more efficiently. I'm all for a smaller foot print.

WTF are you talking about man? Did we just read the same article?

 

[zzz777]

Too bad the hottest components are off-middle on the cpu, not centered. It's a fantastic idea, but you can't just shift a cpu heatsink a couple inches and expect it to work for most people. Expect some pretty exotic shapes.

 

[dark_lord69]

I'm seeing words like motor and bearing...
Does the top heatsync part rotate like a fan?
The article doesn't say...

 

[CheesyHotDogPuff]

Me wants.

 

[cats_Paw]

Yeah, yeah, When it comes out for my PC?

 

[prophetzarquon]

Dear DIY community,

Please get right on this.

 

[cats_Paw]

Looks promising. Id be interested in this quite a lot if i wasent alraedy on the watercooling level.
I wonder however if this can be used on GPU coolers to make them smaller than todays behemonts that we get from powerfull GPUs.

and it can slice potatos for a dinner!

Call me back when the heat is easier to remove from the chip itself. I've seen an older i7 (in person) cooled to 60 with a Hyper 212 Evo, despite the 130W TDP.
