A motherboard will usually have a fan speed control graph where you can set speeds based on cpu temperature.
The default will usually ramp up as the cpu load increases.
You can choose to lower the points on the curve which will result in quieter operation.
900 rpm is usually quiet. 600 rpm is all but inaudible.

Placing the tower further away will make the pc sound quieter.
