This CPU cooler is a mistake of Deepcool marketers =) It's too good for its price, it's easy to install, you don't need to throw off the motherboard, but just click and you're done, from the previous Deepcool cooler with 2 heat pipes and an 80 mm fan, cut off 12-15 degrees in cooling in the load from the overclocked 3570K. It was 75-77, it became 60-65 =) An excellent solution for any processor not higher than + - 110 warm watts. At the same time, I can call it silent, at 100% rpm, it makes noise just like blowing fans. Runs mostly at 50% = 750 rpm.
