Do you hear anything? No? Good!
Looking for a challenge for your next PC build? Try piecing together a quiet system that will hardly let you know it's running without jamming your ear to the side of the case. Not only is it entirely possible to build such a system, but you can build a quiet PC that's still powerful enough to play games, it just takes a little research. One component that could help you along the way is Powercolor's new SCS3 HD7850 , a passively cooled Radeon HD 7850 graphics card.
The card uses G-shape heat pipes that Powercolor says provide the same cooling effect as dual U-shape heat pipes, but with an enlarged surface. It's also armed with solid copper cooling base that fully covers the GPU and lots of aluminum fins to whisk heat away from the card.
Powercolor opted for high quality components to further enhance reliability, such as a Ferrite Core Choke and solid capacitors. As for standard specs, the card's core clockspeed is 850MHz, and its 1GB of GDDR5 memory runs at 1200MHz on a 256-bit bus.
