A new breed of passive graphics card coolers have just made their way onto several mid to high-end graphics cards from Inno3D, these dubbed the "i-Chill" series.
The coolers themselves are actually those of the Accelero S1M and S2M from swiss mob Arctic Cooling, quite unsurprising given they're the best in the biz after all.
You can get to the press release on 'em over at Inno3D's website folks.
Hong Kong 5th March, 2007 - Inno3DŽ i-Chill series are excited to introduce noiseless passive cooling solutions with Arctic Cooling Accelero S2M (2pipes) for mainstream, and S1M (4pipes) for high-end NVIDIAŽ 7 series graphics cards design. It effectively helps remove heat from the graphics card and silently keeps all the components cool.
The Accelero S2M & S1M features a copper base and heatpipes that extend directly from the GPU centre to provide the ultimate heat conductivity and larger surface area. Heat from the GPU can rapidly reach through the Aluminum fins that extend beyond the height of the graphics card. The Aluminum fins are specially designed to allow air flow pass through easily and remove heat efficiently.
