Pros: About what you expect from a new Core i5 processor. Four fast cores, plenty of heat, nice performance.

Cons: Supplied heatsink is mostly useful as a shiny paperweight.

Other Thoughts: The stock Intel cooler is barely passable. Suggest getting a third party heatsink as it seems the days of being able to use a stock CPU cooler are long gone.

Pros: Keeps a hot CPU quite cool and is very quiet.

Cons: How do I count the number of ways it was a PITA to install this cooler?
-The instructions are worthless. Throw these away and Google a guide from a third party.
-The included screwdriver is barely useful. Better not to use it if you don't like stripped out screws.
-The X shaped retention bracket barely fits under the cooler, and you have to blindly line it up in the center and with a pin that clocks it into place. The 'clocking' by the way keeps it from rotating about +/- 5 degrees.
-Have to install the fan dead last, but there's no easy way to get it on or off the cooler without twisting it around due to the slop in clocking.

Other Thoughts: There must be better options out there. Although the price on this model is pretty good, I'm not sure I would buy it again.
