I am running a 3950x and have some ramp up of fans but nothing like you are experiencing. Im on a noctua d15 and its so quiet even when it does ramp up. I dont know much about your bios but i know in my MSI I had to set the fans to pwm and they got even quieter, they were defaulted to voltage control. They never got real loud but I guess they followed with the issue you have, I am running noctua case fans so I guess that may be why they are so quiet.
I would do as alyen says and set low end temps higher
