GV-N650OC-4GI features Triangle Cool Fan Technology, which integrates a patented triangle-shaped aluminum block into the aluminum extrusion module. The triangle design not only minimizes the turbulence between extruded aluminum fins, but also enhances heat dissipation to improve cooling efficiency for the whole fansink. GIGABYTE is able to maximize fan size to 10cm with the upgraded cooling design. With a 10cm fan, the card is virtually silent. With a modified instinctive user interface it is easier to monitor & adjust all important settings. The card supports up to four displays on a single card. Satisfy your multi-screen setup, high definition & extreme gaming experience.
