I did have more noise til I straightened the metal fins that were ever so slightly bent. I swear it is a mix of the fins whistling from being barely bent to the right angle for the fan speeds, and also I think there has to be something wrong with the regulator in the cooler. It only whistles when its running slow. If I start up a complex program it stops with the sound. How do you fix this?
