First Completely Passively-Cooled Graphics Card Developed

Computer, Coolers, Heat Pipes, Heat Sinks, New Products

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 card uses a completely silent cooling assembly for the 3.5 billion transistor GPU.

The card itself is longer than most GTX 680 graphics cards in the market, with a large aluminum fin heat sink spanning its entire length. 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.
