ASUS is going to launch their HD 6770 DirectCU Silent graphics card which uses a passive cooler. More details inside.
ASUS is not the only manufacturer to design a passive cooler for the AMD Radeon HD 6770 graphics card. Back in May, we posted one of the article featuring GIGABYTE's HD 6770 passive graphics card as well (link here). Similar to the GIGABYTE card, the ASUS HD 6770 DirectCU Silent sports a big heatsink (about 95% bigger than the reference HD 6770's heatsink) and DirectCU heatpipes allowing the ASUS passive card to run 16% cooler. It also has HDMI, VGA and DVI outputs.
