Pros: Very Quiet, Solid (You can feel it in it's weight), Better than my E8400 Stock's fan (Stock fan ran at 40C, this runs at 31-32C idle), moves a good amount of air. Runs at 55C full use (using the CPU Stability Heat Warming test after 10 minutes)

Cons: Shipping is a bit expensive for a small product like this.

Overall Review: Fits in a P5E Motherboard, stockfan for the E8400 doesn't fit in there unless you clip some plastic off.

Pros: Price is Great (Got it for Free), it is infact Readyboost ready.

Cons: None

Overall Review: Great Product!
