Danamics - a revolutionary cooling system?!

[Swatrecon_]

He just wants to watch his DirecTV!

[DeltZ]

definitely needs a fan or something. Fins would just heat up and become passive cooler surely

[eXa]

Well, Duh!

Liquid Metal Cooling from quite a few years ago... ...Electro-magnetic pump 'n all...

came in here to post this.

revolutionary my ass.

Edit: wait, I've already posted in this thread? forum necormancers!!

[BulldogPO]

Yeah, I'm also booked up for review sample for http://mato78.com , I will propably test it against IFX-14 and few other coolers like Xigmatek and Noctua products and decent DIY watercooling.

This was posted on Engadget a few days ago with a pic

Although theres no mounting hardware/holes in the picture, i bet fans will be used.

that's not a new pic:p

The 17th to be exact. I have more information, but none to share.

repost, look a few threads down

[Calmatory]

If the metal is liquid, it does not matter that much how well it conducts. Even if it were to conduct as well as copper, thats still pretty slow. (Have you ever held a copper bar on one end and heated the other?)

Having a higher heat capacity is better, because then it takes a lot more heat energy to heat up the water per degree, which is what you want in a waterblock.

The only reason i can think of for using liquid metal is to use a magnetic pump, so they don't have to rely on moving parts

When the copper bar heats from another end to another, which takes e.g. 3 minutes, for same amount of water in same shape(keeping the water still) it would take 30 hours, if not more.

[WaxCactus]

Wow Thats hell of a bump

this liquid metal thing sounds promising

[Slovnaft]

anything that characterizes itself as 'revolutionary'...

[iddqd]

FWIW I'm pretty sure hydrogren is the champion, but there are also alot of polar organics that are much higher than water as well and won't blow up so easily :p.

Water is a pretty good coolant. Good heat conductivity, and excellent capacity (although you can get away with low capacity, you'll just need to pump more coolant or pump it faster).

[Calmatory]

Tbh the heat conductivity of water is terrible at best. Better than air though, but FAR from any metal.

What does heat conductivity have to do with cooling in the case of a moving liquid tho? About nothing?

How does water cooling work then ?

[dinos22]

hey Rob
you got any numbers to show us

[Monkeywoman]

from what i found, the "liquid" is Galinstan which is an alloy of gallium, indium, and tin.

source; http://en.wikipedia.org/wiki/Galinstan

so the conductivity is 16.5 Wmk for Galinstan and Water is 0.691

source; http://hypertextbook.com/physics/thermal/conduction/

soo this cooler should kick ass.

[cabbspapp]

Any ideas on how much this thing is gonna cost us?

[Calmatory]

What does heat conductivity have to do with cooling in the case of a moving liquid tho? About nothing?

Quite a bit, depending on the turbulence of the liquid. If the conductivity is zeroish, then extreme turbulence is needed for the same results for liquid with good(+100 WmK) conductivity. Though, this issue is minimal ad unnoticeable but under special circumstances it could become an issue. Then again, thats far from average computer water cooling system.

To the topic: Danamics - TRUE with EXTRAHYPERVERYGOOD heatpipes, double the price.

I'm mostly worried about the pumping capacity, not so much the base design, liquid and fins. We'll know shortly.

[nefariouscaine]

I remember lurking on this when it got blasted on Engadget forever and a day ago - if I had price and performance number I am open to looking more at this but I'm not too optimistic on it performing much better than higher end heatpipe coolers

[Caveman787]

It looks like it's got 5 8mm heatpipes, if that's so and it's got good liquid flowing well around the heatsink, it may work well.

Problem I see with it is how will it be cooled, even water needs a fan and it doesn't look like a fan would would hit but 1 heatpipe.

nothin yet, im trying to get a sample, i do have the coolermaster v8 and some others on the test bed and i have a preview coming up of new commander unit power supplys from in-win, we got 2 of the 1200 watt units so one is headed off to jonny guru (oklahoma).
