"During the testing sessions I was surprised at how little noise emanated from the two fans even at full test load. Since both Assassin II fans are on one PWM fan hub controller, they both ran the same speed and hit 1280 RPM at full Load testing. Any appreciable noise was a "smooth" flow sound, and not the "whooshing" type noise you normally expect from large fans."
