"The Zalman VF700-AlCu LED videocard graphics processor
intended to cool quietly, with a little
blue LED illumination to spice things up. The heatsink is constructed of
the same fan-shapped fin design that has made Zalman a well know
manufacturer, and it's a design that has many positive thermal attributes.
With its mix of aluminum and copper fins, the Zalman
VF700-AlCu LED is a slightly lighter option for GPU cooling than its VF700-Cu
cousin, weighing 180 grams. The 80mm illuminated fan is set askew slightly from
the center of the VF700-AlCu so that exhaust air passes through the copper and
aluminum cooling fins to adjacent videocard memory, offering some nice
additional cooling to these warm components."
