What's the biggest volume in your setup?
It seems you're dealing with your case fans. You might consider swapping a few low-dB fans for the case fan and/or CPU cooler fans. Noise can feel like trying to catch a dragon's tail—you eliminate the loudest source and then notice others become louder. In the end, replacing the case fan or adding another could help keep everything cooler and quieter.
