Pros: Awesome cooling even in passive mode. Lowered a VisionTek 4850 from 79c Idle/90c load to 43c idle/60c load. That's serious. Gonna strap a 140mm yate loon to see how much cooler it goes.
Cons: HUGE - not really a con if you have the case for it. Fins can be sharp. Be careful.
Overall Review: Voltage heat sink is too long for the 4850. I ended up using zalman ram sinks (the blue ones). There are 4 screws that let you adjust the plate position. The 4850 requires the alternate position for clearance. Pretty simple, though.
