“With the Radeon HD 4870 X2 using two RV770 graphics
cores, this graphics card is quite long (about 27cm) and the cooler
itself is quite large. There is a single (but quite powerful) fan
that pulls air through this very large copper heatsink and is then
pushed out the back of the second slot on this graphics card. Due
to this large heatsink, the graphics card is quite heavy as
well.”
