Cons: Large and tall. Especially tall! Did not fit in my two cases. The fan blows parallel to the line between the two clip anchors on the AM2 socket. With my two motherboards, that would have had it blow to the top of the case rather than the back where my exhaust is.
Summary: I did not find assembly to be a big problem, although the instructions provided could be better.
Pros: Very quiet fan - not audible at the highest RPM. Fairly efficient cooling. Still need to test under full CPU load, but I am pretty sure it can handle 130W thermal design power envelope
Cons: 1. The thing is tall - it does not fit in most standard ATX mid-tower cases. I have 3 different cases from different manufactureres, and it does not fit in any of them. It's too tall by about 10 mm. This is especially annoying since it did not need to be this tall. Now I have to make a cut-out in...
