I just got an email from AMD yesterday evening that AMD is shipping out coolign kits to reviewers, this must be it. A watercooling bundle for AMD's 8-core FX "Bulldozer" chips. It's unknown which models will be available with this cooler, which looks rather similar to the Antec Kuhler H2O 920.
The Asian site XFastet has posted up four pictures of the new water cooler that AMD will be offering for improved cooling of the new 8-core processors.
