This CPU cooler is doing what he is and also very good. From this standpoint, clearly 5 star. What I do not understand, however, is this: You buy this cooler if you have a high-end video editing PC needs (as in my case) or even for gaming. However, the cooler is so large that it smoothly 4 (!) My 8 RAM slots projects that are thus unusable. I use the Asus x79 Delux with a total of 32GB HyperX Beast Kigkston RAM. I'll send the cooler back and probably buy me a water cooler. So do not make the same mistake as I informed you before buying but if it fits.
