The Alpha is an architecture that will be around for the next 20 years
For starters, guys showed a concept design for HD2900XT, and we know of at least one partner that plans to bring this product to market. This Reference Series is stackable, so CoolIT in CrossFire or even more should not be out of reach.
Very clean design should even enable LED perversions, if acrylic cover is used...
Like other products from CoolIT, these coolers are maintenance-free, so when the factory-sealed system is delivered, there is not much that can go wrong.
Guys from CoolIT worked with folk from former ATi HQ, now known as AMD Thermal Laboratory, and cooler utilizes micro-channel technology for highest percentage of heat-dissipation, putting the design of this cooler back to single-slot world. As soon as we get the system, we'll get back to you with the test results.
Something important is not to be missed here. Even in the generic press release, is it noted that this cooler is fully compliant with Hammerhead reference board, or putting no less than four R600 cards onto the same system. Quad Crossfire? You can bet on that. ยต
