Summary: Because most people don't buy this processor for the cooler, I'll overlook that. However, the cooler does seem to work fine, and probably will for most as this particular unit is not overclockable like the 4670K is. Used in a hackintosh, this chip paired with good ram and an SSD will fly. It has been very reliable so far and the performance boost from my 3 year old Macbook Pro (1st gen i5) is astounding. If you never plan to overclock, get this one.
Summary: I returned this unit to go a different way. I'm sure this is a fine product like all Intel products. My decision to go with an AMD fx8320 was simply based on performance per dollar. The AMD device was on sale at amazon, so I took advantage of their offer.
