Liquid Metal Cooling on Sapphire Graphics Cards!
Hey, in case you haven't heard, Sapphire has announced that they are coming out with some crazy new cooling technology using liquid metal to cool some of their graphics cards. Supposedly the liquid metal is 65X more thermally conductive than water, uses no moving parts and is nearly silent. This is freakin' crazy! You've all got to read about this. Here are some links. Check it out...

Nice tip, trowand! I wonder where that will lead to in the CPU HS department...

"Liquid Metal" a.k.a. Mercury? Well I just hopes the pipes don't break because it's conductive and posionous.
Cool ideas - but how many people even use water cooling? |

I use water cooling but this sounds great! Anyone know where I can get a bucket of mercury........
Poisonous, bah I used to play with it when I was a kid and only grew an extra arm.

That will probably add a lot to the cost to the card
 ... but that seems like a pretty sweet idea. I was sorta thinking of that the other day, just like put a bag of water (or mercury  ) ontop of a card to cool it. LOL

Let's hope liquid metal performs better in this application than it does in making softball bats - Rawlings Liquid metal softball bat is terrible.
Okay - I know there's no point to this - but I just got back from playing in a softball tourny and I saw a Rawlings Plasma (liquid metal) softball bat and it didn't hit any better than a $20 WalMart bat.

I heard that the liquid metal would probably be something like iron in a liquid base.

I was thinking, how about covering the whole card, making it looks just like a dead box with only connector pins seen outside. And it's not just an ordinary dead box. It's a non-conductive cool-liquid-metal
It's not just cooling the chip but also all other components. It's a cool, dead box...

As far as I've experienced and read, Murcury is EXTREMELY heavy. If it was cooled with murcury, the card would weigh a couple pounds. You'd have to support the card somewhere or it would end up damaging the PCI-e slot.

These products don't use mercury. There's no way that a new product containing a significant amount of liquid mercury would get past the CPSC and EPA.
There are a number of specialty alloys that melt at very low temperatures. For example, Rose metal (mp = 212 F) and Wood's metal (mp = 160 F). The alloy that Nanocoolers is using is made from gallium, indium, and tin, and apparently is liquid at room temperature. It certainly has a high heat capacity and thermal conductivity. Whether this substance is a substitute for old-fashioned fans and heat sinks is another question. If one of these contraptions leaked, the highly conductive metal certainly would short everything under the hood, and it probably would be difficult to clean up. Maybe Billy Mays can come up with a new product: Kaboom, Liquid Metal Edition. Guaranteed to dissolve gallium residue, or your money back!

Nice tips, that was in the expos a couple of months ago but its nice to see its gone past the usual vaporising promises of innovative tech...

Darn, it was too good to be true.
Apparently this was just more ATi vapourware, announced in May btw http://theinquirer.net/?article=25164 For those of you asking about the metal it is in fact "a cocktail of gallium and indium with a dash of tin which flows freely at temperatures as low as 10 degrees centigrade" fedz
