Pretty much what everyone else stated and to add: I'm not a fan of that CPU cooler, it's difficult to mount the fan on the heatsink using the rubber pieces. Sliced my finger open with the aluminum fins when I did it the first time. I would get something more user friendly. Perhaps a Zalman or a Thermalright or Noctua or scythe HSF? There's a lot out there and they're all roughly about the same performance wise and they have a flat solid base.
