Yeah, it not only keeps the CPU cool it keeps the entire system cool since I have pretty good airflow. The Room I'm in is around 75F and my case will always remain at 20C. My CPU always remains in the 30's celsius and will only go into the 40's if A) I don't turn my CPU fan up all the way and atleast put one of the side blowers on half, or B) If it's just really hot in the room or something.
