Possessing an i5 3570k with motherboard MSI Z77A-G45, playing my processor has climbed over 70 degrees after hours of game and other things open at once (with cooler original Intel). After installing the cooler be quiet, I do not ride more than 51 degrees in charge !!! And then what silence !!! It's simple, once properly adjusted fan, rest is inaudible and support I hear a sentence. So it is worth its price. Please note all times, the bug is large and can not be mounted on your motherboard. On mine the assembly passes right. Would recommend without worries
