"The companies newest videocard heatsink is called the Zalman
VF900-Cu, and it offers wider GPU compatibility
with the large variety of ATI and nVidia videocards that on the
market. In fact, five different mounting hole styles are supported! Unlike the
ZM80D-HP which used heatpipes and front and rear mounted aluminum cooling fins,
the Zalman VF900-Cu occupies space on the front of the videocard only.
about 96mm in diameter, the VF900-Cu is entirely constructed of copper
components, with two 5mm diameter heatpipes looping around the outside of
its many thin cooling fins."
