Pros: Easy to install. Inexspensive. Smaller size doesn't interfere with with ram or other componets unlike some of the cartonishly large air coolers.

Cons: The fan tended to get really loud when the processor actually called for cooling. Was not at all noticeable under idle loads, but when it kicked on, boy did you notice. Also did a below average job of actually keeping the CPU cool. Have noticed 15-20 degree temp drops on my new cooler, so a pretty big difference.

Overall Review: This cooler went in easy and is fairly cheap, but ultimately I would recommend going with a better unit. The 2011 series chips aren't cheap, so in my opinion you might as well protect them with a good cooler. I ended up switching to Intel's liquid cooler and while that was a bit annoying to install, it does a WAY better job of cooling, while staying quiet and is not really that much more expensive.
