Over at CES ASUS is showing of a rather huge ASUS Radeon HD 6970 DirectCu II Graphics Card.

"The EAH6970 DirectCu is perhaps the largest among the company's graphics cards that use a "direct-copper" GPU cooler in which heat pipes make direct contact with the GPU die. Such is the size of the cooler, that the card requires three expansion slots in your system. To make optimal use of the expansion brackets, ASUS wired out all TMDS links from the GPU, yielding a display connectivity consisting of two DVI and four full-sized DisplayPort 1.2 connectors.

The GPU cooler makes use of a large aluminum fin array which uses at least three 8 mm thick copper heat pipes. The aluminum fins are cooled by the airflow of two 120 mm fans. The card uses 2 GB of high-speed GDDR5 memory over a 256-bit wide memory interface, it packs 1536 VLIW4 stream processors. The card also seems to be using a 9-phase VRM that allows software voltage control. Power is drawn in from two 8-pin PCI-E power connectors" as Techpowerup reports.
