The specifications for the GPU cooler posted on Cooler Master's website show us that they have used a copper core and three copper heatpipes with aluminum fins. The heatsink itself is not large, however with the large fan shroud and air duct it appears the cooler will take up most of the size of the graphics card. With modern video cards however it is not uncommon for the stock cooler to nearly cover the entire card. Something noticeably missing from the product description is a list of exactly which video chipsets the CoolViva Pro is compatible with. Cooler Master simply claims a universal clip design to fit both ATI and nVidia based cards.
