"Colorful is the first manufacturer to develope a completely passive cooler for Nvidia’s GeForce GTX 680 graphics card. Called the Colorful iGame GTX 680 Passive Edition. The main heat sink design consists of 140 aluminum fins, and heat from the GPU is transferred by seven 8 mm-thick heat pipes. The main GPU block has grooves for an additional six 8 mm-thick heat pipes that bridge it to the optional, secondary heat sink that can be attached to the reverse side of the card. Together, the two heat sinks provide a 20,000 cm2 surface area for heat dissipation
