Gigabyte 9600 GT Review
 

Today's double-slot width passive cooler works quiet well: it is made with higher quality materials, and is able to rapidly radiate excess heat. The "Multi-Core Cooling" (as Gigabyte calls it) refers to two copper cooling nodes, which help control convection, leading to better thermal dispersion. Heat flows from the GPU via copper pipes to be dissipated out of two separate banks of aluminum fins. Furthermore (and I believe Gigabyte is only company to feature this) cooling fins extend through the rear bracket of the card, directly outside of your case, which is a nice touch, as it keeps internal case temperatures down just that little bit more than usual, in comparison with other passive cooling solutions.
