Cool with this CPU cooler Intel i7-2600K and am idling at 22 degrees, which I only did not believe. Under load (computer games) the temperature of the CPU is between 40 and 50 degrees. It cools with thanks to its size and the top-flow design, the motherboard and the memory. I was skeptical at first whether he really is the right one for my system, but it has proven to be a complete success. At this price, you get nothing better, as long as you pay attention, that the monster also fit into the case. Strong buy recommendation from my side!
