Pros: I used the stock CPU fan/heatsink from my Intel i5-4570 and it was getting much too hot for my liking. When I stress tested with Prime95 two of my cores reached 101°C before I could even finish the test according to Core Temp 1.0. After installing this fan/heatsink and performing the same stress test my maximum temperature on any core was 52°C. Can't hear it over my graphics card.

Cons: Much bigger than I was expecting,but it still fits in the case.

Overall Review: You could probably get the same results with something cheaper; but this just gets the job done right, and gets it done quick.
