techPowerUp posted a review on the Zotac Passive GeForce 8600 GT ZONE Edition
Zotac's new GeForce 8600 GT ZONE Edition is running without any form of active cooling. It also has an audio input which allows you to feed external audio into the HDMI stream which is output via DVI plus an adapter, which is included of course. For a price of $129, or about $10 over a regular 8600 GT you will get several added benefits for very little extra cost.Zotac Passive GeForce 8600 GT ZONE Edition Review
