Sapphire Showcases Radeon Video Cards with Vapour Chamber Coolers
ATI's official partner Sapphire Technology is showcasing a new type of video card cooling at CeBIT 2009. The VGA heatsink incorporates Vapour Chamber technology and will be featured on some of the Sapphire Radeon HD 4850 and Radeon HD 4870 video cards to come. The Vapour Chamber technology is a rather new kind of cooling technology for video cards, and until now it was used only by ASUS. In essence, it is very similar to the heat-pipe technology we've seen plenty of times before, taking heat and transferring it away from its source to a cooler area. However, in the Vapour Chamber technology the cooling effect is achieved not by a gas, but by a vacuum chamber. The heatsink occupies two PCI slots, and also features a big fan on top. Unfortunately, that's all the information we have for now.

It was not the coolest cooler for the Prescotts , but for this use , it possibly helps well. :)
This new version of the Vapor-X cooler is more of a revamp, than anything really new. Bigger fan, redesigned heatsink with "vapour chamber" technology, and a different shroud.
Interesting, to say the least...
FUNNY!I thought my SAPPHIRE 3870 TOXIC had vapor chamber too...
They must really take customers for idiots!!!!!!!!
Not even the hd2900 nor any of the x2 cards had 2 of those and from what i see its 6x2
I agree its very strange if it does have that many connectors.
Damn I feel dumb :laugh:
A silent system is the best...
To Vacum the heat thru the heatpipes could work, but the outer layer of the heatpipes would have to be engineered to compensate in cases of heat being too much for the vacum system.
Its not a new idea, and it probably hasnt kicked off yet because im sure they would suffer the above symptom untill improved in time. The Fan makes sure the card stays at ideal temperatures.
Damn thermal resistance. . .
Newton's law of cooling pisses me right off!
You can see the connector on the first pic, its sticking out a bit.
The first and last pics are of the same card, using 1 6-pin PCI-E connector. Mainly showing off the "new" cooler. Could be a HD4850.
The middle pic is of a different card, using 2 6-pin PCI-E connectors. Mainly showing off the backside memory heatsink. Could be a HD4870 with 2GB GDDR5 memory (hence the memory heatsink on the back).
