Pros: Very quiet. Cooling very well: temperature dropped from 90s to 40s (Celsius degrees)

Cons: Installation instruction very stingy. Parts for other model, which does not fit with Radeon HD 4850. A little too big (had to remove modem)

Overall Review: In comparison to my original HD4850 cooler, this one is huge, but also the difference is huge. My temp. recently was going up to 107 Celsius degrees, now it is between 45 and 49.
