Review: Ok. - Ok.
Review: Good Product! - This is a good product for the price and will cool CPU only @ OC 4ghz (Intel i7 2700k) to about 30c ambient temp. and under full load playing Crysis 3 for 2-3 hours highest it got to was 58c. My advice if that's not cool enough, get a bigger radiator. But I'm very happy with the result as stock was 40c ambient temp. and 85c after 10 minutes of Crysis 3!
