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.
