Thermaltake DuOrb VGA Cooler Review
 

Many vendors of cooling systems use the open fan designed implemented in the Thermaltake DuOrb VGA cooler, however Thermaltake put two smaller fans and heatsinks on this design in order to spread the cooling love to the entire surface of the video card, including the RAM. While it doesn't appear to help much for full-load temperatures, the DuOrb certainly keeps the idle temperatures down. ThinkComputers has the review.
