XtremeComputing has posted a review on the Titan Eagle VGA Heatsink
The large copper base provides an excellent cooling with load temperatures 12C cooler than the stock cooler and the quiet fan makes sure you don't have to compromise silence for temperatures too, which is excellent. The looks might not be everyone's thing with all that gold on the copper version, but if that is the case there is the aluminium version available which is silver.Titan Eagle VGA Heatsink Review
